Answer:
2.5v + 5 < 5v is the correct answer.
Step-by-step explanation:
Given that:
Cost to rent one game at store S = $2.50
Monthly fee = $5.00
Let,
v be the number of video games.
Total cost = 2.50v + 5
Cost to rent one game at store T = $5.00
y = 5v
Now,
Store S < Store T
2.50v + 5 < 5v
Hence,
2.5v + 5 < 5v is the correct answer.

Calculate the speed of a wave with the frequency of 100 hz and wavelength of 250 m, please.
I've been struggling with this one...
Answer:
25000m/s
Step-by-step explanation:
The following formula is used to calculate the speed or velocity of a wave.
V = f * w
Where V is the velocity (m/s)
f is the frequency (hz)
w is the wavelength (m)
First, determine the frequency.
Calculate the frequency of the wave.
Next, determine the wavelength.
Calculate the wavelength of the wave.
Finally, calculate the wave speed.
Using the formula above, calculate the wave speed.

Question 5 (5 points)
(04.05 MC)
Which graph best represents the function f(x) = 4(1.5)x? (5 points)
Question 5 options:
1)
graph of increasing exponential function going through point 0, 2
2)
graph of increasing exponential function going through point 0, 3
3)
graph of increasing exponential function going through point 0, 1
4)
graph of increasing exponential function going through point 0, 4
Answer:
I am guessing the equation you meant to type is [tex]f(x)=4(1.5)^x[/tex]. Based on this information, I know that the answer is:
4) Graph of increasing exponential function going through point (0, 4).
Step-by-step explanation:
I graphed the function in Desmos, and I found that the y-intercept is (0,4). Answer choices 1-3 all have varying y-intercept options, while option number 4 says the graph is going through point (0,4) so we know that's the right answer.
I hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and good luck with the rest of your assignment. I'll attach a photo of the graph below, so you understand the graph.
Answer:
I had the same exact problem on my quiz! The answer is D, because the y intercept is (0,4). Graphing the equation really helped me understand it! :)
A computer software vendor wants to estimate the number of times a computer will crash with its new operating system over the course of a year. A system administrator installs the operating system on a random sample of 34 computers. At the end of a year, the sample mean number of crashes is 5.6, with a standard deviation of 2.2. Find the confidence interval at a 90% confidence level for the mean number of crashes a computer will have with the new operating system over the course of a year.
Answer:
(4.9793, 6.2207)
Step-by-step explanation:
Given the data:
Sample size, n = 34
Sample mean, m = 5.6
Standard deviation, s = 2.2
Confidence interval = 90%
Using the relation :
m ± Zcritical * s/√n
Zcritical at 90% confidence interval = 1.645
Confidence interval ;
5.6 ± (1.645 * 2.2/√34)
5.6 ± 0.6206533
Lower boundary = 5.6 - 0.6206533 = 4.9793
Upper boundary = 5.6 + 0.6206533 = 6.2207
Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the given curves about x = 4. y = 3x4, y = 0, x = 2
Answer: the volume V generated by rotating the regions 281.49
Step-by-step explanation:
Given that;
the radius of the shell ⇒ (4 - x)
then the circumference of the shell is 2π( 3 - x ) i.e 2π × radius
y = 0 and x = 2
the height of the shell is 3x⁴
Now the volume of the solid obtained by rotating
the bounded region about x = 4 is;
V = ²∫₀ 2π ( 4 - x ) ( 3x⁴ ) dx
= ²∫₀ 2π ( 12x⁴ - 3x⁵ ) dx
= 2π [ 12x⁵/5 - 3x⁶/6 ]₀² {BY FTC -2]
= 2π [ (12×32)/5 - (3×64)/6 ] - ( 0-0) ]
= 2π [ 76.8 - 32]
= 2π [ 44.8 ]
= 281.49
Therefore the volume V generated by rotating the regions 281.49
Find the measure of the largest angle in the triangle
shown.
15x
24x
21x
Answer:
72°
Step-by-step explanation:
Find the image of the question attached
The sum of angle in a triangle is 180°
Hence:
15x+24x+21x = 180°
60x =180
x =180/60
x= 3
Get the largest angle
The largest angle out of the angles is 24x
24x =24(3)
24(3) =72°
Hence the measure of the largest angle is 72°
Solve the following inequality: 10t + 7 , 200 > 21 , 000
Answer:
t > 1380
Step-by-step explanation:
Subtract 7200 from both sides
10t + 7200 - 7200 > 21000 - 7200
Simplify
10t > 13800
Divide both sides by 10
10t/10 > 13800/10
Simplify
t > 1380

Square OABC is drawn on a centimetre grid.
O is (0,0) Ais (3,0) Bis (3, 3) C is (0, 3)
Write down how many invariant points there are on the perimeter of the square when
OABC is reflected in y = x
Answer:
No invariant point
Step-by-step explanation:
Yo!
When we translate a form, in this case a polygon We must observe the direction of the vector. Since our vector is:
1) Let's apply that translation to this polygon, a square. Check it below:
2) The invariant points are the points that didn't change after the transformation, simply put the points that haven't changed.
Examining the graph, we can see that no, there is not an invariant point, after the translation. There is no common point that belongs to OABC and O'A'B'C' simultaneously. All points moved.

How many 1/8 are in 13/16?
9514 1404 393
Answer:
13/2 or 6 1/2
Step-by-step explanation:
We can write the question in the form of an equation:
13/16 = n×1/8
Multiplying by 8 gives ...
8×13/16 = n
13/2 = n = 6.5
The number of 1/8 in 13/16 is 6 1/2 or 13/2.

What are the solutions to the absolute value inequality |x − 70| ≤ 3?
Remember, the inequality can be written as −3 ≤ x − 70 ≤ 3
or as x − 70 ≤ 3 and x − 70 ≥ −3.
Answer:
67 ≤ x ≤ 73
Step-by-step explanation:
The absolute value of a real number x is the non negative value of x. Therefore the absolute value of x (|x|) = x for x ≥ 0 and -x for x < 0.
An expression |x - a| = b signifies that x - a = b or -(x - a) = b
Given that |x − 70| ≤ 3, hence:
|x − 70| ≤ 3
x - 70 ≤ 3 or -(x - 70) ≤ 3
x ≤ 3 + 70 or x - 70 ≥ -3
x ≤ 73 or x ≥ -3 + 70
x ≤ 73 or x ≥ 67
67 ≤ x ≤ 73
Hence the solution of |x − 70| ≤ 3 is 67 ≤ x ≤ 73

Natalie went to the store to buy some cherries. The price per pound of the cherries is $6.25 per pound and she has a coupon for $2.75 off the final amount. With the coupon, how much would Natalie have to pay to buy 5 pounds of cherries? Also, write an expression for the cost to buy pp pounds of cherries, assuming at least one pound is purchased.
Answer: 6.25(5) - 2.75 = X
Step-by-step explanation:
Each pond costs 6.25 and she buys 5 pounds so multiply 5.25 and 5. Then subtract 2.75 which is the coupon to get your answer.
The expression is 6.25x - 2.75 = P
P being the total cost

Assume the 72-gon is a regular polygon. The measure of one interior angle is how many
degrees, and the measure of one exterior angle is how many degrees?
9514 1404 393
Answer:
interior: 175°exterior: 5°Step-by-step explanation:
The sum of exterior angles is 360°, so the exterior angle can be easiest to find first.
exterior angle = 360°/72 = 5°
The interior angle is the supplement of this.
interior angle = 180° -5° = 175°
The measure of one interior angle is 175°; one exterior angle is 5°.
