Answer:
Step-by-step explanation:
100(133-380)/380=-65%
So the discount was 65%
Step-by-step explanation:
g(-2)=2(-2)^2 +7(-2) -4
=8 -14 -4
= -10.
j(20)= -5-4(20)
=-5-80
= -85
Answer:
72
Step-by-step explanation:
if you subtract 4 each time then it would look like:
202-4=198
198-4=194
etc. ...
76-4=72
Answer:
Shyla will pay about 63 cents to cover the box
Step-by-step explanation:
Length of the box ( l ) = 7 inches
Width of the box (b) = 11 inches
Height of the box (h) = 8 inches
<em></em>
<em>We can solve this equation by following two simple steps.</em>
1. The first step is to find the total surface area of the box. This is the total area that the decorative fabric will be covering.
We can get this by the following formula:
SA=2( length X width) +2( length X height )+2(height X width)
SA = 2( 7 X 11 ) + 2(7 X 8) + 2 (8 X 11 ) = 442 square inches
2. The second step is to divide the total surface area by the price of the fabric per square inch.
This will be 442 square inches divided by 7 cents per square inch = 63.14 cents
Shyla will pay about 63 cents to cover the box
Answer:
g(x) = x+1
Step-by-step explanation:
Informally, you can see that the function h(x) takes the root of a value that is 1 more than the value under the same radical in f(x). This suggests that adding 1 to x in f(x) will give you h(x). That is, ...
h(x) = f(x+1) = f(g(x))
so
g(x) = x+1
_____
More formally, you can apply the inverse of the function f(x) to the equation ...
h(x) = f(g(x))
f^-1(h(x)) = f^-1(f(g(x))) . . . inverse function applied
f^-1(h(x)) = g(x) . . . . . . . . . simplified
Now f^-1(x) can be found by solving for y in ...
x = f(y)
x = ∛(y+2) . . . . . . . . . definition of f(y)
x^3 = y+2 . . . . . . . . . cube both sides
x^3 -2 = y = f^-1(x) . . . subtract 2 from both sides
So, f^-1(h(x)) is ...
f^-1(h(x)) = g(x) = (∛(x+3))^3 -2 = x+3 -2
g(x) = x+1
