Prove by mathematical induction that 1+2+3+...+n= n(n+1)/2 please can someone help me with this ASAP. Thanks
Let
[tex]P(n):\ 1+2+\ldots+n = \dfrac{n(n+1)}{2}[/tex]
In order to prove this by induction, we first need to prove the base case, i.e. prove that P(1) is true:
[tex]P(1):\ 1 = \dfrac{1\cdot 2}{2}=1[/tex]
So, the base case is ok. Now, we need to assume [tex]P(n)[/tex] and prove [tex]P(n+1)[/tex].
[tex]P(n+1)[/tex] states that
[tex]P(n+1):\ 1+2+\ldots+n+(n+1) = \dfrac{(n+1)(n+2)}{2}=\dfrac{n^2+3n+2}{2}[/tex]
Since we're assuming [tex]P(n)[/tex], we can substitute the sum of the first n terms with their expression:
[tex]\underbrace{1+2+\ldots+n}_{P(n)}+n+1 = \dfrac{n(n+1)}{2}+n+1=\dfrac{n(n+1)+2n+2}{2}=\dfrac{n^2+3n+2}{2}[/tex]
Which terminates the proof, since we showed that
[tex]P(n+1):\ 1+2+\ldots+n+(n+1) =\dfrac{n^2+3n+2}{2}[/tex]

B. -* + 3y = 0
c. 5x - 3y = 0
D. 3x + 5y = 0
E. -3x + 5y = 0
Answer:
B. 5x + 3y = 0Step-by-step explanation:
Parallel lines have the same slope.
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points A(-3, 0) and B(-6, 5). Substitute:
[tex]m=\dfrac{5-0}{-6-(-3)}=\dfrac{5}{-3}=-\dfrac{5}{3}[/tex]
The line passes through the origin, therefore the y-intercept is equal to 0.
Therefore we have the equation:
[tex]y=-\dfrac{5}{3}x[/tex]
Convert to the standard form [tex]Ax+By=C[/tex]
[tex]y=-\dfrac{5}{3}x[/tex] multiply both sides by 3
[tex]3y=-5x[/tex] add 5x to both sides
[tex]5x+3y=0[/tex]
The equation of the line parallel to AB passing through the origin is 5x - 3y = 0.
The equation of the line that passes through the origin and is parallel to AB is 5x - 3y = 0.
To find the equation of a line parallel to AB passing through the origin, we first need to find the slope of AB, which is (5 - 0) / (-6 + 3) = 5 / -3 = -5/3.
Since the line passing through the origin and parallel to AB has the same slope, its equation will be of the form y = mx. Substituting the point (0, 0) into y = -5/3x gives us y = -5/3x, which simplifies to 5x - 3y = 0.

g(t) = 0.1t^2 - 4t + 70
Find the expression that describes the total trout population in the area after t months, f(t) + g(t).
A. 0.1t^2 + 5.5t +120
B. 0.1t^2 - 5.5t +120
C. 0.1t^2 - 2.5t + 120
D. 0.1t^2 + 2.5t + 120
Answer:
Option C.
Step-by-step explanation:
We know that
f(t) = 1.5t + 50
represents the approximate population of trout in Sky Lake
And
g(t) = 0.1t^2 - 4t + 70
represents the approximate population of trout in Lake Cyan
The total trout population in the area is described as
f(t) + g(t)
f(t) + g(t) = [1.5t + 50] + [0.1t^2 - 4t + 70]
f(t) + g(t) = [1.5t + 50+ 0.1t^2 - 4t + 70]
f(t) + g(t) = [0.1t^2 -2.5t + 120]
f(t) + g(t) = 0.1t^2 -2.5t + 120

Lan pays a semiannual premium of $650 for automobile insurance, a monthly premium of $125 for health insurance, and an annual premium of $450 for life insurance.
The monthly expense is $? with explanation
Answer:
Monthly Expense = $270.83
Step-by-step explanation:
The semi-annual premium is paid twice a year so,
Automobile insurance premium for whole year = 650*2
= $1300
Monthly premium will be paid 12 times a year so,
Health insurance premium for whole year = 125*12 = $1500
Annual premium is only paid once a year.
So adding all the premiums will give us the total premiums for whole year.
Total amount of premium for a year = $1300+$1500+$450
= $3250
The premium amount for whole year is $3250. To find the monthly expense, we will divide it by 12.
So monthly expense is:
= 3250/12
= $270.83 ..
To find the monthly expense, calculate the total annual premium for each insurance and divide by 12. The monthly expense is $187.5.
Explanation:To find the monthly expense, we need to calculate the total annual premium for each insurance and divide it by 12 (since there are 12 months in a year).
For automobile insurance, the semiannual premium is $650, so the annual premium is $650 * 2 = $1300.
The monthly premium for health insurance is $125.
For life insurance, the annual premium is $450.
Now, let's calculate the total monthly expense: ($1300 + $125 + $450) / 12 = $187.5.
So, the monthly expense is $187.5.

Craig has 72 feet of material to build a fence around a rectangular flower bed on his property. If the width of the fence must be 3 feet, what is the length of the fence in yards if he uses all 72 feet of material
Answer:
33 feet.
Step-by-step explanation:
Perimeter of a rectangle = 2*width + 2*length.
So here we have:
2*3 + 2*L = 72 where L = the length.
2L = 72 - 6 = 66
L = 33 feet.
Craig has 72 feet or 24 yards of material, with a stated width of 3 feet (1 yard). Subtracting the width of two sides from the total perimeter (24 yards), we find that the length of Craig's fence is 22 yards.
Explanation:Craig has 72 feet of material to build a fence around a rectangular flower bed, with the width required to be 3 feet. To calculate the length of the fence in yards, we first need to find out the total perimeter in yards. Since Craig is using all 72 feet of material, this is the perimeter of the fence. We know that 1 yard is equal to 3 feet, so we convert 72 feet to yards.
To do this division, 72 feet ÷ 3 feet per yard = 24 yards. So, Craig has 24 yards of fencing material in total.
If one side (width) of the flower bed is 3 feet, which is equivalent to 1 yard, we must subtract the width of the two opposite sides from the total perimeter to find the total length of the fence. 24 yards total perimeter - 2 yards total width = 22 yards total length. Therefore, the length of Craig’s fence in yards is 22 yards.

Speed typist #1 can type 95 words each minute. Speed typist #2 can type 98 words each minute. Working together, how many minutes will it take them to type 2,895 words?
Answer:
It will take them 15 minutes.
Step-by-step explanation:
1. Since you are given the information that the two typists are typing a certain amount of words in the same time frame (ie. one minute), you can add the two values together to obtain the total number of words the typists would type together in one minute:
95 + 98 = 193 words
2. To calculate how many minutes it would take them to type 2,895 words, you would simply take this total number of words and divide it by the number of words they collectively type in one minute (found in 1.). Thus:
2895/193 = 15
Therefor, it will take them 15 minutes to type 2,895 words.
Final answer:
To type 2,895 words, they would need approximately 15 minutes.
Explanation:
To solve this problem, we must first find the combined typing speed of both typists when working together.
Speed typist #1 can type 95 words per minute, and speed typist #2 can type 98 words per minute.
Together, they can type 95 + 98 = 193 words per minute.
Next, we need to calculate how many minutes it will take for them to type 2,895 words at this combined rate.
So, we divide the total number of words by the words per minute:
2,895 / 193 = 15 minutes
Therefore, it will take both typists working together approximately 15 minutes to type 2,895 words.

What is the volume of the cylinder below?
Answer:
[tex]\large\boxed{D.\ 2160\pi\ units^3}[/tex]
Step-by-step explanation:
[tex]\text{The formula of a volume of a cylinder:}\\\\V=\pi r^2H\\\\r-radius\\\H-height\\\\\text{We have}\ r=12\ \text{and}\ H=15.\ \text{Substitute:}\\\\V=\pi(12^2)(15)=\pi(144)(15)=2160\pi[/tex]
The volume of the cylinder is [tex]\( 2160 \pi \)[/tex] units³.
To find the volume of the cylinder, we'll use the formula for the volume of a cylinder, which is given by:
[tex]\[ V = \pi r^2 h \][/tex]
Where:
- V is the volume of the cylinder,
- r is the radius of the cylinder, and
- h is the height of the cylinder.
Given:
- Height h = 15 units
- Radius r = 12 units
We'll substitute these values into the formula:
[tex]\[ V = \pi \times (12)^2 \times 15 \][/tex]
[tex]\[ V = \pi \times 144 \times 15 \][/tex]
[tex]\[ V = 2160 \pi \][/tex]
So, the volume of the cylinder is [tex]\( 2160 \pi \)[/tex] cubic units.
The correct answer is option D: [tex]\( 2160 \pi \)[/tex] units³.

As a laboratory assistant, you measure chemicals using the metric system. For your current research, you need to measure out 45 grams of sodium chloride. The bottle you are using lists the amount in ounces. About how many ounces of sodium chloride will you need?
Answer: 1.587 ounces of sodium chloride
Step-by-step explanation:
We know that 1 ounce is equivalent to 28.35 gr.
So we use this as a conversion factor to find the equivalent amount of sodium chloride in ounces.
If we need 45 grams of sodium chloride then this equals to:
[tex]45\ g* \frac{1\ ounces}{28.35\ gr} = 1.587\ ounces[/tex]
Finally you need 1.587 ounces of sodium chloride
Answer:
1.587 ounces
Step-by-step explanation:
We need to measure out 45 grams of sodium chloride using the bottle mentioning units of measure in units.
We are to find the number of ounces of sodium chloride that we will need.
We know that:
1 ounce = 28.35 grams
So using the ratio method to find the number of ounces of Sodium Chloride needed.
[tex]\frac{1 ounce}{x} =\frac{28.35 g}{45 g}[/tex]
[tex]= \frac{45}{28.35} = [/tex] 1.587 ounces

False.
b. logₐB - logₐc = logₐ(b/c)
True.
c. log₄(5x+16) = log₄5x+log₄16 = 2 +log₄5x
False.
d. log₄(5x*16) = log₄5x+log₄16 = 2 +log₄5x
True.
e. logₐ(3x)₂ = 2 logₐ3 + logₐx
False.
f. logₐ(3x)₂ = 2 logₐ3 + 2 logₐx
Answer:
a. False
b. True
c. False
d. True
e. False
f. True
Step-by-step explanation:
By properties of logarithms:
a. False: ㏒ₐb-㏒ₐc ≠ (㏒ₐb / ㏒ₐc) does not exists that property
b. True: (㏒ₐb)-(㏒ₐc) = ㏒ₐ(b/c) Logarithm of a Quotient
c. False: Does not exists the property: ㏒ₐ(c+b) = ㏒ₐc + ㏒ₐb
so
㏒₄(5x+16) ≠ ㏒₄5x + ㏒₄16 but, ㏒₄16 + ㏒₄5x = 2 + ㏒₄5x
because ㏒₄16 = 2.
d. True: Logarithm of a Product: ㏒ₐ(c×b) = ㏒ₐc + ㏒ₐb
so
㏒₄(16×5x) = ㏒₄16 + ㏒₄5x = 2 + ㏒₄5x
e. False: Logarithm of a Power: ㏒ₐ(c×b)ⁿ = n ㏒ₐ(c×b) = n (㏒ₐc + ㏒ₐb) = n ㏒ₐc + n ㏒ₐb
so
㏒ₐ(3x)² ≠ 2 ㏒ₐ3 + ㏒ₐx
f. Correct use of property in point e.
Which of the following is an equivalent form of the compound inequality −33 > −3x − 6 ≥ −6?
The given compound inequality doesn't have any solutions because it creates a contradictory situation where x needs to be both greater than 9 and less than 0 at the same time, which is not possible.
Explanation:The given compound inequality is −33 > −3x − 6 ≥ −6. To find the equivalent form, let's solve it step by step.
First, add 6 to all sides, resulting in -27 > -3x > 0.
Then, divide by -3. Remember that when dividing by a negative number, the direction of the inequality changes. So, we get 9 < x < 0.
This indicates that x is greater than 9 but x also needs to be less than 0. This, however, is a contradictory situation because a number cannot be both greater than 9 and less than 0 at the same time. So, there are no solutions for this inequality.

An equivalent form of the compound inequality −33 > −3x − 6 ≥ −6 is x > 9.5 or x ≤ 0.
To find an equivalent form of the compound inequality −33 > −3x − 6 ≥ −6, we can break it down into two separate inequalities:
−33 > −3x − 6
−3x − 6 ≥ −6
To simplify the first inequality, we can add 6 to both sides: −27 > −3x. Then, we can divide both sides by -3, remembering to flip the inequality sign since we are dividing by a negative number: x > 9.5.
To simplify the second inequality, we can add 6 to both sides: −3x ≥ 0. Then, we can divide both sides by -3, remembering to flip the inequality sign: x ≤ 0.
Therefore, an equivalent form of the compound inequality −33 > −3x − 6 ≥ −6 is x > 9.5 or x ≤ 0.
