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
X^2+14x-176=0
(x+22)(x-8)
x=-22,8
This is because the 2 numbers in the factorisation must have multiple of 176& and a sum of 14
Answer:
the first one is proportion
Step-by-step explanation:
and second one is non proportion hope help you
Answer:
y = x + 3
Step-by-step explanation:
y = mx + b
m is the slope
b is the y intercept
if m = 1 and b = 3 then
y = x + 3
Answer:
C(8,14)
Step-by-step explanation:
initial point (-3,-5) and terminal point (5,9)
vector form=(change in x, change in y)
V=(Xf-Xi,Yf-Yi)
V=[5-(-3), 9-(-5)]
V=(8,14)
