the simplified value of the exponential expression is 1/9
Answer:
18 i hope this helps! :)
Step-by-step explanation:
has 16 to begin with
gets 10 more
16 + 10 = 26
gives 8 away
26 - 8 = 18
Manu has 18 pears left
Answer:
164
Step-by-step explanation:
65+65=130
17+17=34
130+34=164
The answer is 894cm<span> ². 13 x 9 x 2 + 15 x 9 x 2 + 15 x 13 x 2 = </span>894
The vertex form is
f(x) = a(x - (-1))^2 - 108 = a(x + 1)^2 - 108 where a is some constant.
from the y intercept x = 0 when f(x) = -105, so substituting:-
-105 = a (0+1)^2 - 108
a = -105+108 = 3
so our equation is f(x) = 3(x + 1)^2 - 108
for x intercept:-
3(x +1)^2 - 108 = 0
(x + 1)^2 = 108 / 3 = 36
x+ 1 = +/- sqrt36 = +/- 6
x = -7 or 5
so the x intercepts are at ( (-7,0) and (5,0)
