Hi there! The answer you're looking for is $72.30. Simply multiply $482 by 0.05 (5%) and multiply that answer by three (three years) to get $72.30! Let me know if this helps! <3
Answer: $72.30
Step-by-step explanation: To solve this problem, first begin with the interest formula.
Formula: Interest = principal × rate × time
In this problem, we are solving for the interest.
The principal is the amount invested which in this case is $482. The rate is 5% which we can write as .05 and the time is 3 years.
Interest = (482)(.05)(3)
Interest = 72.3
This means that the interest earned is $72.30.
Please help me with this circle area problem for geometry
Answer:
circle area = PI * radius^2
circle area = 11^2 * PI
circle area = 121 * PI
That would be the area for the ENTIRE area but the circle but we are only dealing with 135 degrees of a circle so the area equals
121 * (135 / 360) * PI

What is the slope of this line? Enter your answer as a number, like this: 42, or, if the slope is undefined, enter the lowercase letter "u".
[tex]\bf \begin{array}{|cc|ll} \cline{1-2} x&y\\ \cline{1-2} {-2}~~\ast&{4}~~\ast\\ 0&2\\ 1&1\\ {3}~~\ast&{-1}~~\ast\\ \cline{1-2} \end{array}~\hspace{10em} (\stackrel{x_1}{-2}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-1-4}{3-(-2)}\implies \cfrac{-5}{3+2}\implies \cfrac{-5}{5}\implies -1[/tex]
The slope of this line is -1.
The slope formula is useful:
m = (y2 -y1)/(x2 -x1)
where:
m is the slope of the line
y1 and y2 are the y-coordinates of two points on the line
x1 and x2 are the x-coordinates of the two points on the line
m = (2 -4)/(0 -(-2)) = -2/2 = -1
The slope of this line is -1.
The points on the line drop 1 unit for each 1 unit to the right.
m = rise/run = -1/1 = -1

Which of the following would best be solved using factoring by grouping?
1) x^2+3x- 10=0
2)3x^2+12x=8
3)x^2=25
4)x^3+ 5x^2- 9x- 45=0
Answer:
The fourth
Step-by-step explanation:
It has 4 terms
ANSWER
4)x^3+ 5x^2- 9x- 45=0
EXPLANATION
Factoring by grouping is used to factor expressions that have four terms.
Among the given options, the fourth option is
[tex]x^3+ 5x^2- 9x- 45=0[/tex]
There are already four terms in this expression.
So we group the first two and the last two and factor.
We can see that x² is common to the first two terms and -5 is common to the last 2 terms.
The fourth choice is correct.
Question: A manufacturer keeps track of his monthly costs by using a “cost function” that assigns a total cost for a given number of manufactured items, x. The function is C(x) = 7,500 + 2.4x a) What is the reasonable domain of the function? b) What is the cost of 3,500 items? c) If costs must be kept below $20,000 this month, what is the greatest number of items she can manufacture? You must show your work
Answer:
a) Domain: -∞ < x < ∞
b) Cost required to manufacture 3500 items is $15,900.
c) Number of items she can manufacture is 5208 if cost is kept at $20,000
Step-by-step explanation:
a) What is the reasonable domain of the function?
The function is C(x) = 7,500 + 2.4x
The domain of the function is the set of values for which the function is defined and valid.
In the given function there is no constraint or undefined points so domain is:
-∞ < x < ∞
b) What is the cost of 3,500 items?
We are given x = 3500 and we need to find the cost.
Putting values in the function given:
C(x) = 7,500 + 2.4x
C(x) = 7,500 + 2.4 (3500)
C(x) = 7500 + 8400
C(x) = 15,900
Cost required to manufacture 3500 items is $15,900.
c) If costs must be kept below $20,000 this month, what is the greatest number of items she can manufacture?
We are given cost, and we need to find x
C(x) = 7,500 + 2.4x
20,000 = 7500 +2.4x
20,000 - 7500 = 2.4x
12500 = 2.4 x
=> x = 12500/2.4
x= 5208.3 ≅ 5208
So, Number of items she can manufacture is 5208 if cost is kept at $20,000

C. 3/70
D. 70/3
The answer is D.
If you multiply them all together the answer (without simplifying), it should equal 210/9, you then simplify the numerator and denominator by 3 and you get 70/3.
Answer:
D
Step-by-step explanation:
Given
[tex]\frac{5}{3}[/tex] × [tex]\frac{2}{3}[/tex] × [tex]\frac{21}{1}[/tex]
Multiply numerators/ denominators
= [tex]\frac{5(2)(21)}{3(3)(1)}[/tex]

A sales representative from a local radio station is trying to convince the owner of a small fitness club to advertise on her station. The representative says that if the owner begins advertising on the station today, the club's total number of members will grow exponentially each month. She uses the given expression to model the number of club members, in hundreds, after advertising for t months. 1.8(1.02)^12t What does the value 1.8 represent?
Answer:
The value 1.8 represent the club's total number of members today or the present number of members
Step-by-step explanation:
Given an exponential function;
[tex]y=ab^{x}[/tex]
b is the base or the growth factor
a is the initial value, that is the value of y when x = 0
We have been given the exponential function;
[tex]y=1.8(1.02)^{12t}[/tex]
The value 1.8 simply represents the initial value of y. Plug in t = 0 in the equation;
[tex]y=1.8(1.02)^{12(0)}=1.8[/tex]
Therefore, the value 1.8 represent the club's total number of members today or the present number of members.
Ieda bakes 73 cupcakes and accidentally drops 5 of them. She divides them equally into 13 containers for a bake sale for the school band. How many cupcakes does Ieda have left
Answer:
3 left
Step-by-step explanation:
If she starts out with 73 and drops 5 she is left with 68, an you cannot evenly divide 68 and 13 so you divide it as much as you can evenly which is five containers leaving 3 extra cupcakes.
For this case we have that initially there are 73 cupcakes, if Leda dropped 5 then we are left with:
[tex]73-5 = 68[/tex]
Now, you must equally divide the 68 cupcakes into 13 containers:
putting 5 cupcakes in each of the 13 containers we have;
[tex]13 * 5 = 65[/tex]
[tex]68-65=3[/tex]
So, we have 3 cupcakes left.
Answer:
3 cupcakes
Given: - 1/2x > 6.
Choose the solution set.
{x | x R, x > -12}
{x | x R, x < -12}
{x | x R, x > -3}
{x | x R, x < -3}
Answer:
It's option 2.
Step-by-step explanation:
- 1/2x > 6
Divide both sides by -1/2:
x < -12 (Note the inequality sign flips when we divide by a negative value).
Answer: {x |x ∈ R, x < -12}
Step-by-step explanation:
Given the following inequality:
[tex]-\frac{1}{2}x>6[/tex]
You can find the solution set by solving for the variable "x".
Then, to solve for the variable "x" you need to multiply both sides of the inequality:
[tex](-\frac{1}{2}x)(2)>(6)(2)[/tex]
[tex]-x>12[/tex]
And finally, you must multiply both sides of the inequality by (-1). Notice that the direction of the symbol of the inequality will change:
[tex](-x)(-1)>(12)(-1)[/tex]
[tex]x<-12[/tex]
Therefore, the solution set is: {x |x ∈ R, x < -12}

John wants to measure the height of a tree. He walks exactly 100 feet from the base of the tree and looks up. The angle from the ground to the top of the tree is 33o . How tall is the tree?
Answer:
The height of the tree is [tex]64.94\ ft[/tex]
Step-by-step explanation:
Let
y ----> the height of the tree
we know that
[tex]tan(33\°)=y/100[/tex] ----> the function tangent is equal to divide the opposite side angle of 33 degrees by the adjacent side angle of 33 degrees
Solve for y
[tex]y=(100)tan(33\°)=64.94\ ft[/tex]
The height of the tree can be calculated using the formula 'Height of tree = tan(33 degrees) * distance from the tree'. Substituting the given values, the tree should be approximately 65.45 feet tall.
Explanation:John can measure the height of the tree using trigonometric principles. In this case, the problem involves a right triangle, where the height of the tree forms one side (opposite to the angle of elevation), the distance John is from the tree forms the base (adjacent to the angle of elevation), and the line of sight to the top of the tree forms the hypotenuse. The tangent of the angle of elevation (33 degrees in this case) is equal to the height of the tree divided by the distance from the tree.
Therefore, to calculate the height of the tree, we need to find the tangent of the given angle and multiply it by the distance from the tree:
Height of tree = tan(33 degrees) * distance from tree
= tan(33) * 100 feet
Approximately, the tree should be around 65.45 feet tall.

3 1/3 divided by 2/3
Answer:
5
Step-by-step explanation:
(3 1/3)/(2/3) = (10/3)/(2/3) = 10/2 = 5
In the above, both the numerator fraction and the denominator fraction have the same denominator (3), so the result is the ratio of their numerators.
____
The other way to divide fractions is to "invert and multiply". For this, the denominator gets inverted (from 2/3 to 3/2) and that is then used to multiply the numerator.
(3 1/3)/(2/3) = (10/3) · (3/2) = (10·3)/(2·3) = 10/2 = 5
You will note that the denominators of 3 cancel, resulting in 10/2 as above.

What is the midpoint of the segment shown below
Answer:
D
Step-by-step explanation:
Using the midpoint formula
midpoint of 2 points (x₁, y₁ ) and (x₂, y₂ ) is
[ [tex]\frac{1}{2}[/tex](x₁ + x₂), [tex]\frac{1}{2}[/tex](y₁ + y₂ ) ]
let (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (5, 5), then midpoint is
[ [tex]\frac{1}{2}[/tex](- 1 + 5), [tex]\frac{1}{2}[/tex](5 + 5) ]
= (2, 5) → D
The midpoint of the segment is (2,5).
To find the midpoint of a line segment with endpoints [tex]\((-1, 5)\) and \((5, 5)\)[/tex], we can use the midpoint formula:
[tex]\[ \text{Midpoint} = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \][/tex]
Given the endpoints:
[tex]\( x_1 = -1 \), \( y_1 = 5 \)[/tex] (coordinates of the first point)
[tex]\( x_2 = 5 \), \( y_2 = 5 \)[/tex] (coordinates of the second point)
Now, let's plug these values into the midpoint formula:
[tex]\[ \text{Midpoint} = \left( \frac{-1 + 5}{2}, \frac{5 + 5}{2} \right) \][/tex]
[tex]\[ = \left( \frac{4}{2}, \frac{10}{2} \right) \][/tex]
[tex]\[ = \left( 2, 5 \right) \][/tex]
Therefore, the midpoint of the segment is (2, 5)
Among the given options, the correct one is option D: (2, 5).
What proportion results in the equation 9m=10n
It might have come from
9/n = 10/m
Answer: Hi, in the equation 9*m = 10*n the proportion is 9 to 10, which means that 9 times the number m is equal to 10 times the number n.
So n is proportional to m in the way that n= (9/10)*m
and m is proportional to n in the way that m= (10/9)*n
This means that the proportion can be written as 9 to 10, or 9:10.
