Simplify the following radical expression :<br> 3√12 × 5√6

Hoochie [10]

$3 \sqrt{12} *5 \sqrt{6} = 15 \sqrt{72}$ .

Simplifying the radical, we have <u /> $15 \sqrt{72} = 15*6 \sqrt{\frac{72}{6^{2}} } =90 \sqrt{2}$ , so our answer is $90 \sqrt{2}$ .

Equation of the parabola in vertex form that passes through (4,-7) and has a vertex of (1,-6)

Alina [70]

$y = -\frac{1}{9}(x - 1)^2 - 6$

Step-by-step explanation:

The vertex form of the equation for a parabola is given by

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

where (h, k) are the coordinates of the parabola's vertex. Since the vertex is at (1, -6), we can write the equation as

$y = a(x - 1)^2 - 6$

Also, since the parabola passes through (4, -7), we can use this to find the value for a:

$-7 = a(4 - 1)^2 - 6 \Rightarrow -7 = 9a - 6$

$a = -\frac{1}{9}$

Therefore, the equation of the parabola is

$y = -\frac{1}{9}(x - 1)^2 - 6$

Marcus solved for x in the quadratic equation x2 – 10x + 25 = 0. x = x = x = What is true about Marcus’s work? Check all that ap

aniked [119]

Marcus should have substituted -10for b, not 10
Marcus should have subtracted 4(1)(25) in the square root
This equation, when solved correctly, only has one real number solution

So A, C, D

Answer:

$25.57

Step-by-step explanation:

First, you have to multiply $5.29 by 2 because she wants to spend $5.29 on 2 pairs of socks.

5.29 * 2 = $10.58

Then you want to add $10.58 and $14.99 together.

$10.58 + $14.99 = $25.57
