ANSWER
[tex]S_4 = \frac{208}{375} [/tex]
EXPLANATION
The given series is:
[tex]\sum_{n=1}^{\infty} \frac{2}{3} ( - { \frac{1}{5} })^{n - 1} [/tex]
When n=1, the first term is
[tex]a = \frac{2}{3} [/tex]
The sum of terms of a geometric sequence is given by the formula;
[tex]S_n = \frac{a {(1 - {r}^{n} )} }{1 - r} [/tex]
The sum of the first 4 terms is:
[tex]S_4= \frac{ \frac{2}{3} {(1 - { ( - \frac{1}{5} )}^{4} )} }{1 - - \frac{1}{5} } [/tex]
[tex]S_4 = \frac{208}{375} [/tex]
The value for S4 is represented by the third option, [tex]\frac{208}{375}[/tex] .
Geometric SequencesYou can define a geometric sequence when you have a common ratio between the numbers of a sequence. This common ratio can be found when you multiply or divide the previous term by the next term of the sequence and you find the same value. The formula for geometric sequences is:
[tex]a_n=a_1*r^{n-1}[/tex], where:
[tex]a_n[/tex]=[tex]n^{th}[/tex] term
[tex]a_1[/tex]= the first term
Example
2, 4,8, 16, ....
Here, you have:
[tex]a_1[/tex]= 2
[tex]r=\frac{a_2}{a_1}=\frac{a_3}{a_2}=2[/tex] , then: 2 x 2= 4; 4 x 2=8; 8 x 2=16 - Note that the numbers represent the example sequence.
For solving this exercise also it is necessary to apply the formula for the geometric sequence for finite terms since the question asks [tex]S_4[/tex], in the other words, the sum for n=4. Thus,[tex]S_n=\frac{a_1*(1-r^n)}{1-r}[/tex].
For the given series, when n=4, you have
[tex]\frac{2}{3} *(\frac{-1}{5})^{n-4} \\ \\ \frac{2}{3} *(\frac{-1}{5})^{4-4}\\ \\ \frac{2}{3} *(\frac{-1}{5})^{0}\\ \\ \frac{2}{3} *1=\frac{2}{3}[/tex]
Therefore, [tex]a_1=\frac{2}{3}[/tex].
Now, you will find S4 from the formula for the geometric sequence for finite terms
[tex]S_n=\frac{a_1*(1-r^n)}{1-r}\\ \\ =\frac{\frac{2}{3}\cdot \left(1-\left(-\frac{1}{5}\right)^4\right)}{1-\left(-\frac{1}{5}\right)}\\ \\ \frac{\frac{2}{3}\left(1-\left(-\frac{1}{5}\right)^4\right)}{1+\frac{1}{5}}=\frac{\frac{416}{625}}{\frac{6}{5}}=\frac{416\cdot \:5}{625\cdot \:6}=\frac{208}{375}[/tex]

In a recent student government election, the ratio of students who voted for the winner to all the students who voted was 0.64. The number of students who voted was 125. How many votes did the winner get?
Answer:
80
Step-by-step explanation:
The total was 125
0.64 of them voted for the winner.
The number who voted for the winner = ratio * total
Votes for the winner = 0.64 * 125
Votes for the winner = 80
if the driver looks 49 inches above the road bed, at what distances from the tower will the drivers eyes be at the same height as the cable?
Replace h with 49 ( the given height) and solve for d ( distance).
49 = d^2 - 36d +324
Subtract 49 from both sides:
0 = d^2 - 36d + 275
Factor the polynomial, by finding two numbers when added together equal -36 and when multiplied equal 275.
(d-25)(d-11) = 0
Now solve for d by setting both equations to 0:
d-25 = 0
d = 25
d-11 = 0
d = 11
The two distances would be 11 yards and 25 yards.

Given the polynomial 21x 4 + 3y - 6x 2 + 34 What polynomial must be subtracted from it to obtain 29x 2 - 7 ? What polynomial must be added to it to obtain a first degree polynomial?
Answer:
1. 21x⁴+3y-35x² + 41
2. -21x⁴-3y+6x² + x
Step-by-step explanation:
When adding and subtracting polynomials , you can use the distributive property to add or subtract the coefficients of like terms.
1. The polynomial is 21x⁴ + 3y -6x² + 34
To obtain polynomial 29x² -7 , we must subtract some polynomial from it.
Let that polynomial be k.
So, 21x⁴ + 3y -6x² + 34 - k = 29x² -7
k = 21x⁴ + 3y - 6x² +34 - 29x² +7 = 21x⁴ + 3y - 35x² + 41
2. To obtain a first degree polynomial, let that polynomial be x +34
So, 21x⁴ + 3y - 6x² + 34 + K = x + 34
K = x + 34 - 21x⁴ -3y + 6x² - 34
= -21x⁴ - 3y + 6x² + x

a car drives 52 km at a speed of 13km/h. how long does the journey take
Answer:
The journey took 4 hours.
Step-by-step explanation:
The relationship between distance, speed, and time is expressed in the formula;
[tex]Speed=\frac{Distance}{Time}[/tex]
The car covered 52 km at a speed of 13km/h.
This means that; distance =52km and speed =13km/h
We substitute the given values into the formula to get;
[tex]13=\frac{52}{Time}[/tex]
[tex]Time=\frac{52}{13}[/tex]
This simplifies to:
[tex]Time=4hrs[/tex]
The journey took 4 hours.
The speed is the ratio of distance to time. Then the time taken by the journey is 4 hours.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity.
We know that the speed formula
[tex]\rm Speed = \dfrac{Distance}{Time}[/tex]
Then the time is given as
[tex]\rm Time = \dfrac{Distance}{Speed}[/tex]
A car drives 52 km at a speed of 13km/h.
Then the time taken will be given as
[tex]\rm Time = \dfrac{52}{13} \\\\ Time = 4[/tex]

David is filling out orders for an online business and gets paid $1 for each order he fills out plus bonus of 25 cents per order if the average number of orders he completes per day within any of the given weeks exceeds 20. The ratio of the number of orders he processed during the first week to the number of orders he processed during the second week is 3:2, while the the ratio that compares the number of orders he filled out during the first and the third weeks is 4 to 5 respectively. What amount of money will David make at the end of three weeks if the total number of orders he filled out was 385. If necessary, round your answer to the nearest dollar.
Answer:
David will make $481 (he earns the bonus)
Explanation:
If he makes $1 for each order and he filled out 385 orders, then why can't we say he made $385?
Because of this statement rights here:
"...and gets paid $1 for each order he fills out plus bonus of 25 cents per order if the average number of orders he completes per day within any of the given weeks exceeds 20."
So we need to find out if any of the 3 weeks has an average of 20+ orders per day.
David is filling out orders for an online business and gets paid $1 for each order he fills out(x is the amount of orders he fills out)
profit = $1x
plus bonus of 25 cents per order if the average number of orders he completes per day within any of the given weeks exceeds 20.if any average orders per day is > 20 in any week
bonus profit = $1.25x
The ratio of the number of orders he processed during the first week to the number of orders he processed during the second week is 3:2,first week second week
3a : 2a
while the the ratio that compares the number of orders he filled out during the first and the third weeks is 4 to 5 respectively.first week third week
4a : 5a
What amount of money will David make at the end of three weeks if the total number of orders he filled out was 385?sum of all ratios of a = 385
So we have
3a : 2a (first week to second week)
4a : 5a (first week to third week)
Notice how the first two numbers are both from the first week. Let's use the Least Common Multiple to make them equal while still keeping ratios.
LCM of 3 and 4: 12 = 3 * 4
12a : 8a ( times 4 )
12a : 15a ( times 3 )
Now that we have the same value, we can create a big ratio
first week second week third week
12a : 8a : 15a
we know that these ratios will all equal 385. Since ratios are equal no matter how big we make them, we can say that
12a + 8a + 15a = 385 (a is a variable to scale up the ratio)
which is the same as
(12 + 8 + 15) * a = 385
(35) * a = 385
35a = 385
if we solve for a by dividing 35 on both sides we get
a = 11
This gives us how much to multiply the RATIO by to get the ACTUAL NUMBER of orders completed. Let's plug 11 for 'a' and see what happens.
12a + 8a + 15a = 385
12(11) + 8(11) + 15(11) = 385
132 + 88 + 165 = 385 (Check that out, the number of orders each week!)
220 + 165 = 385
385 = 385
Bingo! All the math works out. So, looking back at the verryyy top of this problem, the reason why it wasn't as easy as $385 was because of the bonus.
The bonus gives David $1.25 per order instead of $1 per order if any of the weeks have an average ORDER PER DAY of anything bigger than 20. If we know the real numbers of orders for every week (132, 88, and 165), then we can divide it by 7 to get the average order per day. Let's choose 165 (the third week) because it is the biggest and has the greatest chance of meeting our goal.
165 orders / 7 days (7 days in a week) = 23.57 orders per day
Is this greater than 20 orders per day?
YES!
So now we can safely say that the bonus is there or not, and in this case, the bonus IS there because there is a week where David had more than 20 orders per day.
So instead of using
profit = $1x
We will use
bonus profit = $1.25x
(x is the amount of orders completed)
So if we know he completed 385 orders, and we know he earned the bonus, we plug in 385 for x for the bonus function
bonus profit = $1.25x
bonus profit = $1.25 * 385
bonus profit = $481.25
If necessary, round your answer to the nearest dollar.
So for the very end, all we have to do is round it to the nearest dollar.
$481.25 rounds to $481.
And we're done!
Answer:
426
Step-by-step explanation:
the three totals of orders per week were 132, 88, and 165. David gets a 25 cent bonus only if the average was 20 or more per day in the week, so we divide by 7 to each. The only one that ends up with a quotient greater than 20 is 165 so we do 165*1.25=206.25. we now add up the three totals. 132+88+206.25=426.25. Now we round to the nearest dollar which is 426. And thats our answer!
Sorry if it is a bad explanation.

Find all solutions for a triangle with B=36degrees b=19 c=30
Answer:
m∠A = 76° , m∠C = 68° , a = 31.4
Step-by-step explanation:
* Lets revise how to solve a triangle
- In ΔABC
- a, b, c are the lengths of its 3 sides, where
# a is opposite to angle A
# b is opposite to angle B
# c is opposite to angle C
- m∠B = 36°
- b = 19
- c = 30
* To solve the triangle we can use the sin Rule
- In any triangle the ratio between the length of each side
to the measure of each opposite angle are equal
- a/sinA = b/sinB = c/sinC
* Lets use it to find a and m∠C
∵ m∠B = 36° , b = 19 and c = 30
∵ 19/sin36° = 30/sinC ⇒ by using cross multiplication
∴ sinC = 30 × sin36° ÷ 19 = 0.928
∴ m∠C = sin^-1(0.928) = 68°
- Find measure of angle A
∵ The sum of the measures of the interior angles in a triangle is 180°
∵ m∠A = 180° - (68° + 36°) = 180° - 104° = 76°
∴ m∠A = 76°
- Now we can Find a
∵ a/sinA = b/sinB
∴ a/sin76° = 19/sin36° ⇒ by using cross multiplication
∴ a = 19 × sin(76°) ÷ sin(36°) = 31.4
* m∠A = 76° , m∠C = 68° , a = 31.4
Answer:
Triangle 1A =75.86, B=36, C=68.14, b=19, c=30, a=31.34
Triangle 2A=32.14, B=36, C=111.86, b=19, c=30, a=17.19
Step-by-step explanation:
We have two sides of triangle (b and c) and an angle (B)
To solve the triangle we use the sine theorem:
[tex]\frac{sin(B)}{b}=\frac{sin(C)}{c} =\frac{sin(A)}{a}[/tex]
We substitute the values of b, B and c in the equation and solve for C
[tex]\frac{sin(36)}{19}=\frac{sin(C)}{30}\\\\sin(C) = 30*\frac{sin(36)}{19}\\\\sin(C) = 0.9281\\\\C=arcsin(0.9281)\\\\C=68.14\°\ \ or\ \ C=111.86[/tex]
The sum of the internal angles of a triangle is 180, then
[tex]68.14 + 36 + A=180\\\\A=180-68.14 - 36\\\\A=75.86\°[/tex]
or
[tex]111.86 + 36 + A=180\\\\A=180-111.86 - 36\\\\A=32.14\°[/tex]
No we find "a" for both cases.
[tex]\frac{sin(36)}{19}=\frac{sin(75.86\°)}{a}\\\\0.03094a=sin(75.86\°)\\\\a=\frac{sin(75.86\°)}{0.03094}\\\\a=31.34[/tex]
or
[tex]\frac{sin(36)}{19}=\frac{sin(32.14\°)}{a}\\\\0.03094a=sin(32.14\°)\\\\a=\frac{sin(32.14\°)}{0.03094}\\\\a=17.19[/tex]

The ceiling of Katie’s living room is a square that is 12 ft long on each side. To decorate for a party, she plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner. Katie can buy rolls that each contain 10 ft of crepe paper. What is the minimum number of rolls she should buy? Show your work.
Answer:
The minimum number of rolls she should buy is 9 rolls
Step-by-step explanation:
* Lets study the information in the problem
- Katie wants to put the crepe paper around the perimeter of the
ceiling which shaped a square of side length 12 feet
- And also from each corner to the opposite corner
- She needs the length of the 4 sides of the square and the length
of its 2 diagonals
* Lets find the length of the diagonal of the square
∵ The two adjacent sides of the square formed two legs of a right
angle triangle and the diagonal joining the endpoints of the legs
is the hypotenuse of the triangle
- Use Pythagoras theorem to find the length of the diagonal
∴ The length of the diagonal = √(s² + s²) √(2s²) = s√2
∵ The length of the side of the square = 12 feet
∴ The length of the diagonal = 12√2
* Now lets find the length of the crepe papers she needs
∵ She needs the length of the 4 sides of the square and the length
of its 2 diagonals
∴ The length of crepe papers = 12 + 12 + 12 + 12 + 12√2 + 12√2 = 81.94 feet
∵ Each roll of the crepe papers contain 10 feet
- To find the number of rolls divide the length of the crepe papers by 10
∴ The number of rolls = 81.94 ÷ 10 = 8.194
* She must to buy 9 rolls to have enough crepe papers to decorate
her ceiling
* V.I.N:
- If she decide to buy 8 rolls, some part of ceiling will not decorate
because the 8 rolls have 80 feet only and she needs 81.94 feet
A hypothetical square grows so that the length of it's diagonals are increasing at a rate of 8 m/min. How fast is the area of the square increasing when the diagonals are 4m each?
Answer:
32[tex]m^{2}/min[/tex]
Step-by-step explanation:
We let the length of the square be l, the diagonal be z and the area be A.
Then by Pythagoras theorem;
[tex]l^{2}+l^{2}=z^{2}\\2l^{2}=z^{2}[/tex]
The are of a square of length l is given as;
[tex]A=l^{2}[/tex]
Combining these two equations yields;
[tex]z^{2}=2A[/tex]
[tex]A=\frac{z^{2} }{2}[/tex]
Next, we have been given;
[tex]\frac{dz}{dt}=8[/tex]
We are required to find;
[tex]\frac{dA}{dt}[/tex] when z = 4
By chain rule;
[tex]\frac{dA}{dt}=\frac{dA}{dz}*\frac{dz}{dt}[/tex]
Differentiating [tex]A=\frac{z^{2} }{2}[/tex] with respect to z yields;
[tex]\frac{dA}{dz}=z[/tex]
Therefore,
[tex]\frac{dA}{dt}=\frac{dA}{dz}*\frac{dz}{dt}[/tex] = 8z
When z is 4m the area of the square will be increasing at a rate of;
8m/min * 4m = 32[tex]m^{2}/min[/tex]
The area of the square is increasing at a rate of 32 m^2/min when the diagonals are each 4 meters long. This is calculated using the relationship between the diagonal and the side length of the square, and applying the concepts of calculus.
Explanation:The subject of your question is related to Mathematics, specifically in the field of calculus, which deals with rates of change and accumulation. In this scenario, we're looking at how fast the area of a square is increasing given that its diagonals are increasing at a steady rate.
In a square, the diagonal and the side length 's' have a specific relationship, given by the Pythagorean theorem as diagonal = s * sqrt(2). As the diagonal is increasing at 8 m/min, ds/dt = 8/(sqrt(2)) m/min. Now, the area of a square (A) is given by A = s^2. By differentiating this respect to time 't', dA/dt = 2s*(ds/dt). Substituting the given length of the diagonal (4 m), we find s = diagonal/sqrt(2) = 2 sqrt(2) m. Now, substituting s and ds/dt into the equation for dA/dt, we find dA/dt = 2s*(ds/dt) = 2*2sqrt(2)*8/sqrt(2) = 32 m^2/min. So, the area of the square is increasing at the rate of 32 m^2/min when the diagonals are 4 meters each.

Left by 4 units
Right by 4 units
Left by 8 units
Right by 8 units
Answer:
B, Right by 4 units
Step-by-step explanation:
we want to factor g(x), and the factorization of that would be (x - 4)² as its a perfect square trinomial
when translating on a graph, we determine the translation. the translation of g(x) is a horizontal shift 4 units to the right, as we are subtracting 4. if it was adding 4, we would be shifting to the left 4 units
ANSWER
Right by 4 units
EXPLANATION
The given functions are
[tex]f(x) = {x}^{2} [/tex]
and
[tex]g(x) = {x}^{2} - 8x + 16[/tex]
To obtain how much f(x) is shifted to obtain g(x), we need to rewrite g(x) in vertex form.
Observe that,
[tex]g(x) = {x}^{2} - 8x + ( - 4) ^{2} [/tex]
is a perfect square trinomial.
The vertex form is
[tex]g(x) = {(x - 4)}^{2} [/tex]
When f(x) is shifted 4 units to the right, we obtain g(x).
