. Find f(3) for the following function
[tex]f(x)=3(2)^x+6[/tex]
a.f(3) = 222
b.f(3) = 9
c.f(3) = 24
d.f(3) = 30
Answers
Answer:
[tex]\boxed {\boxed {\sf D. \ f(3)= 30}}[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x)= 3(2)^x+6[/tex]
We want to find f(3), so we must substitute 3 in for x.
[tex]f(3)= 3(2)^3+6[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Solve the exponent first.
2³= 2*2*2= 4*2= 8[tex]f(3)= 3(8)+6[/tex]
Multiply 8 and 3.
[tex]f(3)= 24+6[/tex]
Add.
[tex]f(3)=30[/tex]
For the function given, f(3) is 30.

Samantha bought a refrigerator that is 3 1/2 feet wide, 5 1/2 feet tall, and 2 1/2 feet deep. How much space will the new refrigerator occupy?
Answers
Answer:
48.125 ft³
Step-by-step explanation:
The space occupied by the new generator is the product of it's dimension:
The space occupied = Length * width * height
Space occupied = 3 1/2 * 5 1/2 * 2 1/2
Space occupied = 7/2 * 11/2 * 5/2
Space occupied = (7*11*5) / (2*2*2) = 385 / 8
Space occupied = 48.125 ft³
Which of the following expressions are equivalent to -4/7 - 8/9 + 4/7 + 9/8?
Answers
Answer:
C and D
Step-by-step explanation:
I'm too braindead to explain this, read comments
Answer:
-2 1/72
Step-by-step explanation:
Start by combining -4/7 and 4/7 to make 0, shortening your equation. Then continue by making the fractions remaining, 8/9 and -9/8, have a common denominator. To do this, we multiply -8/9 by 8, and -9/8 by 9. Then, we have -64/72 and -81/72. Then, we can combine the numerators of the fractions, as they have common denominators, and we get the fraction -145/72. We can then simplify this to -2 1/72.

18. A jar contains 200 coins.
• Zack pulls out a coin, records its value, and then puts the coin back into the jar.
• Zack does this same process 8 times and records 1 quarter, 2 dimes, 2 nickels, and
3 pennies.
Based on these results, how many coins in the jar can Zach expect to have a value of
$0.10 or more?
А
75
B.
67
C. 50
D. 25
Answers
Answer:
Step-by-step explanation:
3 coins pulled are 10 cents or more
5 coins are under 10 cents
so 3 out of 8 coins are 10 cents or more
the jar contains 200 coins
This is a ratio problem 3 is to 8 as x (an unknown value) is to 200
3/8 = x/200 solve for x
times both sides by 200
200(3/8) = x solve directly here using a calculator
600/8 = x or keep similifying until you can divide more
300/4 = x easily I kept dividing the numerator and the
150/2 = x denominator by 2 until i got 150/2 = 75
75 = x
You deposit 500 in a savings account that earns 9% annual interest compounded monthly. Enter a function that represents the balance y (in dollars) after t years
Answers
Answer: y = 500 * ( 1 + 0.75%) ^ (t * 12)
Step-by-step explanation:
Formula for calculating the amount of money in an account as a result of compound interest is:
Balance = Amount * ( 1 + rate) ^ no. of periods
This interest is compounded monthly so has to be converted to a monthly rate:
= 9% / 12
= 0.75%
t is in years so has to be converted as well to months:
= t * 12 months
Function is therefore:
y = 500 * ( 1 + 0.75%) ^ (t * 12)

Find the number of sides of a regular polygon if one interior angle is 120 degrees A3 B4 C5 D6
Answers
Answer:
n = 6
Step-by-step explanation
Number of sides = 360/Measure of exterior
Measure of exterior = 180 - interior angle
Exterior angle = 180 - 120
Exterior angle = 60 degrees
Substitute into the formula
number of sides = 360/60
number of sides = 6
Hence the number of sides required is 6
