Answer:
A) Replace L with the length of the skid mark:
Speed = √(20(208))
Speed= √(4160)
Speed = 64.5 miles per hour
B) set the equation to the speed and solve for L:
47 = sqrt(20L)
Square both sides:
2209 = 20L
Divide both sides by 20:
L = 110.5 feet

For the function f(x) = 3x + 2, find x such that f(x) = 14.
Answers
Answer:
x = 4
Step-by-step explanation:
To find x, plug in 14 into the function
f(x) = 3x + 2
14 = 3x + 2
Solve for x
14 = 3x + 2
12 = 3x
4 = x
So, the answer is x = 4

Sergio puts flowers in vases. He puts the same number of flowers in each
vase, as shown in the table below. How many vases does Sergio need for
112 flowers?
Answers
Answer:
Since there is so table shown here, I advice you to divide 112 with the number of flowers in each vase. Like for example lets say that the amount of flowers in each vase is 16. You would need to divide 112 and 16. Thats 7. So the "answer" would be 7. Do the same (divide 112) with the amount of flowers you have in your table.
Cameron has a balance of $10,200 on his credit card. He threw the card away so he can never use it again. He has 3.5 years to pay off the balance. The interest rate on his card is 21%.
At the end of the 3.5 years, how much money in interest alone will Cameron have paid?
When Cameron finally pays off his credit card, how much will he have paid in all?
Answers
Answer:
the interest is $9,676.91 and the future value amount is $19,876.91
Step-by-step explanation:
The computation is shown below;
The future value is
= Present value × (1 + rate of interest)^number of years
= $10,200 × (1 + 0.21)^3.5
= $19,876.91
Now the interest amount is
= Future value - present value
= $19,876.91 - $10,200
= $9,676.91
Hence, the interest is $9,676.91 and the future value amount is $19,876.91
If 8 minus some number divided by 3 = 6 what is the number?
Answers
Answer:
n = 6
Step-by-step explanation:
Represent the unknown number by n. Then 8 - n/3 = 6.
Consolidate the constants on the left side: 2 - n/3 = 0, or n/3 = 2.
Multiplying both sides by 3 results in: n = 6
1. Student ID number at a certain University are made up of a letter, followed by six 1-digit
numbers, and then another letter (example: L132389M). How many student ID numbers are
possible if the letters cannot be repeated? [4 points]
Answers
Answer:
650,000,000 student ID numbers are possible if the letters cannot be repeated.
Step-by-step explanation:
The order in which the digits or letters are placed is important, which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
2 letters from a set of 26(permutations, as letters cannot be repeated).
6 digits, each with 10 possible outcomes.
How many student ID numbers are possible if the letters cannot be repeated?
[tex]T = 10^6 \times \frac{26!}{24!} = 650000000[/tex]
650,000,000 student ID numbers are possible if the letters cannot be repeated.

Answer:
y = [tex](\frac{1}{2})^{-x} +4[/tex]
Step-by-step explanation:
In order to achieve the following transformation we need to do the following. To get the graph to be reflected accross the y-axis we need to change the sign of the x variable. Since the x-variable in this scenario is a positive we would change it to a negative. Next, we want to shift the graph 4 units up. To do this we simply need to add 4 to the entire equation. This would result in the following equation.
y = [tex](\frac{1}{2})^{-x} +4[/tex]
Both of these graphs can be seen in the image below.

Write an equation such that the area of the rectangle is equal to the area of the square. d. Solve the equation in part (c) to find the side length of the square. e. What are the length and the width of the rectangle?

Answer:
a) w(4w-15)
b) w²
c) w(4w -15) = w²
d) w = 5
e) 5 by 5
Step-by-step explanation:
a) If w is the width, and the length is 15 less than 4 times the width, then the length is 4w-15. The area is the product of length and width.
A = w(4w -15)
__
b) If w is the side length, the area of the square is (also) the product of length and width:
A = w²
__
c) Equating the expressions for area, we have ...
w(4w -15) = w²
__
d) we can subtract the right side to get ...
4w² -15w -w² = 0
3w(w -5) = 0
This has solutions w=0 and w=5. Only the positive solution is sensible in this problem.
The side length of the square is 5 units.
__
e) The rectangle is 5 units wide, and 4(5)-15 = 5 units long.
The rectangle and square have the same width and the same area, so the rectangle must be a square.
