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:
If 23-26, that is -3
Well, because 23 can't minus 26, that's why you have to rearrange so that you can find the correct answer by letting -26 + 23.
Answer:
The slope would be 1/2
Step-by-step explanation:
y= mx +b
m= slope
perpendicular lines have slopes that are multiplied in order to get -1
<em>these are important</em>
<em></em>
2x + y = 4
<u><em>subtract 2x</em></u>
y=-2x +4
your slope is -2
-2 * ? = -1
? = -1/-2
? = 1/2
Answer:
-5x
Step-by-step explanation:
-10+5= -5 then you put -5 with x to get -5x
8.25%=8 1/4
8.25% of a gallon is 1.32 cups
Step-by-step explanation:
1/3=33.3%
33.3÷4=8.25%
8.25/1 x 100/100 = 825/100
825+100=8 1/4
