Answer:
solution
given that
ar=8 __________equation 1
r=4
putting r=4in equation 1 we get
a×4=8
a=2
now
t4=ar^(4-1)
= 2×4^3
=2×4×4×4
=128ans
It helps if you have an example, like f(x) = 2x+3
What you typically do, is:
- draw xy axis, label them (ie., 1,2,3,4 along both axes)
- calculate the f(x) values for several x (e.g., -2, 0, 1, 3, doesn't matter).
- plot the calculated values as points. The calculated f(x) is your y value.
- sketch a smooth line through the points. It helps if you know in advance if the line is going to be straight or curved.
- The more points you calculate, the more accurate your graph will be
Since there are three kids, 3x3=9. 80-9=71. Danny and Mark and Evans ages combined is 71 years
The answer is 4+8+16+32+64+128+256+512+1024: This is equivalent to 2044
Step-by-step explanation:
Yes they are equivalent. You get -3 when you try solving the actual equation.
