Answer:
Not if store closes at 5pm. The time store closes isn’t mentioned.
Step-by-step explanation:
If it takes her 35 minutes to drive to the hardware store, she would arrive at 5:05 (4:30+:35 minutes)
The given functions are
![1.\, f(x)= \frac{3}{4}( \frac{7}{4})^{x} \\ \\2.\,f(x)= \frac{2}{3}( \frac{4}{5} ) ^{-x}\\\\3.\, f(x)= \frac{3}{2} ( \frac{8}{7} )^{-x}\\\\4.\,f(x)= \frac{1}{3} ( \frac{9}{2} )^{x}](https://tex.z-dn.net/?f=1.%5C%2C%20f%28x%29%3D%20%5Cfrac%7B3%7D%7B4%7D%28%20%5Cfrac%7B7%7D%7B4%7D%29%5E%7Bx%7D%20%5C%5C%20%5C%5C2.%5C%2Cf%28x%29%3D%20%5Cfrac%7B2%7D%7B3%7D%28%20%5Cfrac%7B4%7D%7B5%7D%20%29%20%5E%7B-x%7D%5C%5C%5C%5C3.%5C%2C%20f%28x%29%3D%20%5Cfrac%7B3%7D%7B2%7D%20%28%20%5Cfrac%7B8%7D%7B7%7D%20%29%5E%7B-x%7D%5C%5C%5C%5C4.%5C%2Cf%28x%29%3D%20%5Cfrac%7B1%7D%7B3%7D%20%28%20%5Cfrac%7B9%7D%7B2%7D%20%29%5E%7Bx%7D)
Evaluate the functions.
1. Because 7/4 > 1 and the exponent is positive,
the function does not decay.
2.Because 4/5 < 1 and the exponent is negative,
the function does not decay.
3. Because 8/7 > 1 and the exponent is negative,
the function decays.
4. Because 9/2 > 1 and the exponent is positive,
the function does not decay.
A composite plot the functions verifies the answer.
Answer:
Answer:
5 × 12 + 3.5 × 12
Step-by-step explanation:
Given:
Number of cupcakes in each box = 12
Number of boxes ordered by Sean for his sister’s graduation party = 5
Number of boxes ordered by Sean for the variety show party = 3.5
To find: an expression that shows the calculations to find the number of the cupcakes Sean orders.
Solution:
( Number of boxes ordered by Sean for his sister’s graduation party × Number of cupcakes in each box ) + ( Number of boxes ordered by Sean for the variety show party × Number of cupcakes in each box )
= 5 × 12 + 3.5 × 12
If the roots are 3, 2 and -3 then the function is created by multiplying
(x-3) * (x-2) * (x+3)
x^2 -5x +6 * (x+3)
x^3 -5x^2 +6x + 3x^2 -15x +18 = 0
x^3 -2x^2 -9x +18 = 0
