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:
<u>114</u>
<u>Steps listed below</u>
Set up the proportion:
<u>36</u> <u> x </u>
120 380
Cross Multiply to get:
120x and 13680
Divide each side by 120:
<u>120x</u> <u>13680</u>
120 120
Answer:
<u>x=114</u>
Answer:
- ASA stands for "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal.
- If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
Step-by-step explanation:
To solve this problem we must substitute

Answer:
Step-by-step explanation:
Although I cannot graph this here, I can solve it.
2(x-8)+4x=20
2x-16+4x=20
6x=36
x=6
Hope this helps!
