Answer:
z = -1
Step-by-step explanation:
add like terms: 13z = -13
divide both sides by 13: z = -1

And, you're not bad at math! You goot this correct! :)
Step-by-step explanation:
c=25.12
we can use this to find the raidus!
-
plug it back into the circumference formula first.
c=(pi)(d)
25.12=3.14*d
divide both sides by 3.14!
d=8 but we need the radius, so we just divide by 2. 8/2 = 4. so the raidus is 4!
-
now we plug it into the area of a circle formula.
π · r2
3.14 * 4^2
3.14*16
50.24
Step-by-step explanation:
with $4,000 invested, Jake has
8% × $4,000 = $320 annually.
in order to have annual interest $628, he has to get more interest $(628-320) = $308.
the rate should be:
308/2800 × 100%
= 308 /2800 × 100%
= 11%

Answer:
A. 6, 24, 96, 384
Step-by-step explanation:
The recursive formula tells you that the next number in sequence is 4 times the previous one.
For first term 6, the second term is 4·6 = 24.
For 2nd term 24, the third term is 4·24 = 96.
For 3rd term 96, the fourth term is 4·96 = 384.
The first four terms of the sequence are ...
6, 24, 96, 384
__
You don't even need to figure all four terms. You know immediately which sequence is correct once you have found ...
