What would be the answer to this question and how would you solve it??
It is #24
Answers
the slope is the change in Y over the change in x
x = the first numbers 5 & 10
y = the second numbers 8 & 12
10-5 =5
12-8 = 4
so slope = 4/5

for the expoential function y= ab^x, which of the following value(s) would produce an expoential decay function?
a. 0<b<1
b. a<0
c. b>1

Answers
A decay function has a distinctive comportment:
"If a < b, therefore f(a) > f(b)"
So, the function must assume smaller values as x grows.
This is accomplished when 0 < b < 1

Jamaal studied h hours for a big test. Karla studied one fourth as long. Write an algebraic expression for the length of time Karla studied. Use this expression to determine the length of time that Karla studied if Jamaal studied for 5 hours and 20 minutes.
Answers
x = (1/4)h
So, if Jamaal studied h = 5 h + (20 min* 1 h/60 min) = 16/3 or 5.333 hours. Thus, Karla's hours would be
x = (1/4)(16/3) = 1.33 hours or 1 hour and 20 minutes.

What are Arithmetic operations?Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
The first trail he hiked on took him 4.5 miles away from his house.
The second trail he hiked took him 2.4 miles closer to his house.
The third trail took him 1.7 miles further away from his house
Here the expression of the given problem and apply the arithmetic operations,
⇒ 4.5 - 2.4 + 1.7
⇒ 2.1 + 1.7
⇒ 3.8
Hence, Andre is 3.8 miles away from his house after hiking the three trails.

translate into an equation Find three consecutive even integers whose sum is negative eighteen
Answers
make x be your first unknown negative even integer. you want your negative x and then negative x minus two and negative x minus four
x1= x
x2= x-2
x3= x-4
you know all three need to equal -18
solve for x:
-18= -x + (-x-2) + (-x-4)
-18 = -x-x-2-x-4
-18+2+4= -3x
12=-3x
12/-3=x
-4=x
then plus x into the first problem.
x1= -4 = -4
x2= -4-2 = -6
x3= -4-4 = -8
so your integers would be -4, -6, and -8
check:
(-4) + (-6) + (-8) = -18

The product of the slopes of two non-vertical perpendicular lines is always -1. It is NOT possible for two perpendicular lines to both have a positive slope because the product of two positives is positive. So for the product of the slopes to be -1, one of the slopes must be positive and the other negative.

A rectangle has an area of 48 cm^2 and a perimeter of 38 cm. what are the dimensions of the rectangle?
Answers
We infer from the question that the dimensions of the rectangle, satisfying both the given area of 48 cm² and the given perimeter of 38 cm, are 12 cm x 4 cm.
Explanation:The topic of this question relates to the geometrical concept of rectangles. We know that the area of a rectangle is determined by the formula Area = length * width and the perimeter is given by the formula Perimeter = 2*(length + width). Given that the area is 48 cm² and the perimeter is 38 cm, we can set up the following equations:
Area = length * width = 48Perimeter = 2*(length + width) = 38Since the Perimeter and Area involve both length and width, we use simultaneous equations to solve this. By trial and error or via substitution method, we find that the dimensions satisfying both conditions are: length = 12 cm and width = 4 cm. Therefore, the dimensions of the rectangle are 12 cm x 4 cm.

A friend eats eats one-fifth of a pizza; you decide to eat half of what was left. How much is left after you eat the pizza?
Answers
If you ate 1/2 of 4/5, you ate 2/5, and you left 2/5. Remember that to find 1/2 of 4/5, multiply the fractions to get 4/10, which simplifies to 2/5.
Final answer: 2/5 of the pizza.
it would be 2/5 since 1/5 is subtracted from your friend, and you are eating half which would be 2/5 since you have 4/5 now and 2/5 = half of 4/5. (Fun Fact: I cant even eat half a pizza).

You’ve written your first novel and, like many first-time authors, can’t find a publisher. So you’ve decided to self-publish your book. You need to work out the cost of printing the book. If the cost of printing the novel includes a base cost of $1,550 plus $4 per book, write a function that represents the cost of printing x copies of the book. Type your response here: If you want to cover the printing costs by printing and selling only 50 copies of the book, at what price must you sell the book?
Answers
selling only 50 copies...
P(50) = 4(50) + 1550
P(50) = 200 + 1550
P(50) = 1750....so the printing cost for 50 copies is 1750
1750 = 50x....x = cost of each book
1750/50 = x
35 = x.......u would have to sell each book for $ 35 <===
Find the exact value for cos π 12 applying sum and difference formulas involving π 3 and π 4 .
Answers
First, split the angle into two angles where the values of the six trigonometric functions are known. In this case, π/12 can be split into π/3−π/4.
cos(π/3−π/4)
Use the difference formula for cosine to simplify the expression. The formula states that cos(A−B)=cos(A)cos(B)+sin(A)sin(B)
cos(π/3)⋅cos(π/4)+sin(π/3)⋅sin(π/4)
The exact value of cos(π/3) is 12, so:
(12)⋅cos(π/4)+sin(π/3)⋅sin(π/4)
The exact value of cos(π/4) is √22.
(12)⋅(√22)+sin(π/3)⋅sin(π/4)
The exact value of sin(π/3) is √32.
(12)⋅(√22)+(√32)⋅sin(π/4)
The exact value of sin(π/4) is √22.
(12)⋅(√22)+(√32)⋅(√22)
Simplify each term:
√24+√64
Combine the numerators over the common denominator.
