When an exponent is outside the parenthesis, you multiply them.

13*19=247

“C” 2^247 is the answer.

Y= -3x^2-24x-46 write in vertex form

mario62 [17]

ANSWER

$y= -3{(x + 4)}^{2} + 2$

EXPLANATION

The given function is:

$y= -3x^2-24x-46$

Factor -3 for the first 2 terms.

$y= -3(x^2 + 8x)-46$

We add and subtract the square of the coefficient of x.

$y= -3(x^2 + 8x + {(4)}^{2} ) - - 3( {4)}^{2} -46$

Factor the perfect square trinomial.

$y= -3 {(x + 4)}^{2} ) + 48 -46$

The vertex form is:

$y= -3{(x + 4)}^{2} + 2$

I need help with this question asap pleaseeeeee

Answer:

y = 3 $\sqrt{7}$

Step-by-step explanation:

The two inner right triangles are similar, thus the ratios of corresponding sides are equal, that is

$\frac{y}{9}$ = $\frac{7}{y}$ ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = $\sqrt{63}$ = $\sqrt{9(7)}$ = $\sqrt{9}$ × $\sqrt{7}$ = 3 $\sqrt{7}$
