$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{1 - 11}{-2 - 3} = \frac{-10}{-5} = 2$

y - y₁ = m(x - x₁)
y - 11 = 2(x - 3)
y - 11 = 2(x) - 2(3)
y - 11 = 2x - 6
+ 11 + 11
y = 2x + 5

How do you simplify (2xy2)3

pantera1 [17]

$(2xy^{2})^{3} = (2xy^{2})(2xy^{2})(2xy^{2})$
Now, we can just multiply it and obtain the result
$(2xy^{2})(2xy^{2})(2xy^{2})=(4x^{2}y^{4})(2xy^{2})=8x^{3}y^{6}$

I used law presented on this example
$2^{3}*2=2^{3}*2^{1}=2^{3+1}=2^{4}$

The lateral area of a cone is 19.2π in2. The radius is 2.4 in. Find the slant height.

Alexus [3.1K]

The slant height of a cone with lateral surface are of 19.2π inches squared and radius of 2.4 inches is 8 inches.

<h3>Lateral surface area of a cone</h3>

The formula for the lateral surface area of a cone is described as follows:

Lateral area = πrl

where

r = base radius
l = slant height

Therefore,

Lateral area = 19.2π inches²

r = 2.4 inches

Lateral area = π × 2.4 × l

19.2π = 2.4πl

divide both sides by 2.4π

l = 19.2π / 2.4π

l = 8 inches
