Hello,
Part A:
f(2)=4*2²=16
f(1)=4*2^1=8
2-1=1
(f(2)-f(1))/(2-1)=(16-8)/1=8 ; r_1=8
f(3)=4*2^3=32
f(4)=4*2^4=64
(f(4)-f(3))/(4-3)=(64-32)/1=32 ; r_2=32
Part B:
r_2=32=4*8=4*r_1
Explainations:
(4*2^2-4*2^1)/(2-1)=4*2^1(2-1)=4*2
(4*2^4-4*2^3)/(4-3)=4*2^3*(2-1)=4*8=(4*2)*4
Answer:
800 Cm
Step-by-step explanation:
bro typa question is that its common sense that 100 cm = 1 meter
Okay! So to start this problem, we need to look at the given information a little closer to make sure we have everything we need! This is a triangular pyramid, meaning that it has a total of 4 sides, which are all congruent triangles, meaning they all have the same surface area! We are also given the total surface area, which is 2304 cm^2.
If we need to find out how big one of the sides are, we should just have to divide the total surface area by 4, because there are 4 sides with the same surface area! 2304/4 = 576 cm^2, so your answer should be A) 576 cm2!
For this case, we must find the inverse of the following function:

To find the inverse we follow the steps below:

We rewrite the denominator:

We exchange variables:

We solve for y:
We multiply on both sides of the equation by (y-7)

We subtract xy on both sides of the equation:

We add 1 to both sides:

We factor for y:

We divide both sides by (-5-x):

So, we have:

Answer:


L = (1⅕)W= (6/5)W
LW = 480 in²
(6/5)W² = 480
W² = 480 × ⅚ = 400
W = 20 in
L = (6/5)W =24 in
