It's 65. Because you add the other angles and get 90+25 and get 115. 180 -115 = 65.

Multiply or divide as indicated. x^-8 • x^-2

gladu [14]

ANSWER

$\frac{1}{ {x}^{10} }$

EXPLANATION

The given exponentiial expression is

${x}^{ - 8} \bullet {x}^{ - 2}$

We simplify using the rule:

${a}^{m} \times {a}^{n} = {a}^{m + n}$

We apply this property to get:

${x}^{ - 8} \bullet {x}^{ - 2} = {x}^{ - 8 + - 2}$

We simplify to get;

${x}^{ - 8} \bullet {x}^{ - 2} = {x}^{ - 10}$

We rewrite as a positive index to get;

${x}^{ - 8} \bullet {x}^{ - 2} = \frac{1}{ {x}^{10} }$

Which equation is equivalent to the formula below?<br>y = a(x – h)^2 + k<br>

PolarNik [594]

Answer:

See below.

Step-by-step explanation:

The given equation is in vertex form. We can convert it to standard form as follows:

y = a(x - h)^2 + k

y = a(x^2 - 2hx + h^2) + k

y = ax^2 - 2ahx + (ah^2 + k) (answer).
