Answer:
(D) t^4
Step-by-step explanation:
You have defined ...
a3 = a2·a1
a4 = a3·(a2·a1) = a3²
a5 = a4·(a3·a2·a1) = a4² = (a3²)² = a3⁴
Then if a3 = t, a5 = t⁴
lox (x) = -5
rewrite the equation in exponential form:
10^-5 = x
10^-5 = 1/10000
1/10000 = 0.00001
That is the correct answer.
Answer:
Point D and It is equivalent to 75%
Step-by-step explanation:
Let’s assume that Laura has x$
Jose = 8+ x
Keith= 3x
So the total is equal to
118= x + 8 +x + 3x
118= 5x + 8
Subtract 8 from both sides
110= 5x
Divide 5 by both sides
22$= x which is what Laura has
Jose will have :8+22= 30$
Keith will have :3*22=66$
Step-by-step explanation:
Simplify :
x4−6x3+2x−7+7x3−x+5x2+2−x4
x4−6x3+2x−7+7x3−x+5x2+2−x4
Rearranging and collecting the like terms, we get:
=(x4−x4)+(−6x3+7x3)+5x2+(2x−x)+(−7+2)
=(1−1)x4+(−6+7)x3+5x2+(2−1)x+(−7+2)
=(1)x3+5x2+(1)x−7+2
=x3+5x2+x−5
