Answer:

AB = 8.0

Step-by-step explanation:

Law of Sines

AB/sin53 = 7/sin44

multiply both sides by sin53

AB = 7/sin44 * sin53

use calculator

AB = 8.047766798861355

Find the later area of the figure

o-na [289]

Answer:

$\large\boxed{60\pi\ sq.in.}$

Step-by-step explanation:

The formula of a lateral area of a cone:

$L.A.=\pi rl$

r - radius

l - lateral height

We have the radius r = 6in and the height H = 8in.

Use the Pythagorean theorem to calculate the lateral height:

$l^2=6^2+8^2\\\\l^2=36+64\\\\l^2=100\to l=\sqrt{100}\\\\l=10\ in$

Substitute:

$L.A.=\pi(6)(10)=80\pi\ in^2$

Find the product. 8y 3(-3y 2)

S_A_V [24]

For this case we must find the product of the following expression:

$8y ^ 3 (-3y ^ 2) =$

We have to by law of signs of multiplication:

$+ * - = -$

Also, by definition of multiplication of powers of the same base, we put the same base and add the exponents, then the expression is rewritten as:

$-24y ^ {3 + 2} =\\-24y ^ 5$

Answer:

$-24y ^ 5$
