Answer:
25 cm^2
Step-by-step explanation:
The side length of square 1 is sqrt(169) = 13
The side length of square 2 is 48/4 = 12
From the Pythagorean Triple 13 - 12 - 5, the side length of square 3 is 5
Finally, 5 * 5 is 25
m + g + 30 = t
If m = 40 and t = 95,
g = t - m - 30 = 95 - 40 - 30 = 25.
Answer:
x=0 x=3 x=-2
Step-by-step explanation:
p(x)= 3x^3 – 3x^2– 18x
Factor out the greatest common factor, 3x
p(x)= 3x (x^2 – x– 6)
Factor inside the parentheses
What 2 numbers multiplies to -6 and adds to -1
-3*2 = -6
-3+2 = -1
p(x)= 3x (x-3)(x+2)
Setting the function equal to zero to find the zeros
0 = 3x (x-3)(x+2)
Using the zero product property
3x = 0 x-3 =0 x+2 =0
x=0 x=3 x=-2
Full question:
A transaction is positive if there is a sale and negative when there is a return. Each time a customer uses credit card for a transaction, the credit company charges Isabel. The credit company charges 1.5% of each sale and a fee of 0.5 % for returns
Let x represent the amount of a transaction and let f(x) represent the amount Isabel is charged for the transaction. Write a function that expresses f(x)
Answer:
f(x)= 0.015(x)
f(x)= 0.005(x)
Explanation:
If Isabel makes a sale, she has a positive transaction and therefore is charged 1.5%(which is 0.015) by the credit company for the transaction. If the product is returned, it is a negative transaction and the credit company charges 0.5%(which is 0.005) for the transaction. The functions for positive and negative transactions would be different as indicated in the answer since transactions( given by x) are different- positive and negative.
