Answer:

Step by step solution:

Not exactly sure what it means to expand the product. But to solve, you always do what's in the paranthesis first. So 2 x 4 = 8. The little number 2 means squared or to the power of, which bascially means you multiply the number by how ever many it tells you. So since it says 8 to the power of 2, you just multiply 8 x 8 which equals 64.

Answer:

y = -1/2x + 1

Step-by-step explanation:

Slope-intercept form:

y = mx + b

Use two of the ordered pairs and find the slope:

m = (1-2)/(0-(-2)) = -1/2

y-intercept is 1 as point (0, 1) is given in the table:

b = 1

The line is:

y = -1/2x + 1

What's the best Approximation? :3

musickatia [10]

Area of shaded region = Area of larger circle - Area of smaller circle.

We know, Area of a Circle = πr²
So, A = πr₁² - πr₂²
A = π (r₁² - r₂²)
A = π(10.2² - 5.4²)
A = 3.14 (104.04 - 29.16)
A = 3.14 (74.88)
A = 235.12

In short, Your Answer would be 235.12 cm²

Hope this helps!

Find the length of the third side. If necessary, write in simplest radical form.

Mazyrski [523]

Answer:

$\boxed {\boxed {\sf 8}}$

Step-by-step explanation:

This triangle has a small square, which represents a right angle. Therefore, we can use the Pythagorean Theorem.

$a^2+b^2=c^2$

Where a and b are the legs of the triangle and c is the hypotenuse.

In this triangle, 7 and √15 are the legs, because these sides make up the right angle. The unknown side is the hypotenuse, because it is opposite the right angle. So, we know two values:

$a= 7 \\b= \sqrt{15}$

Substitute these values into the formula.

$(7)^2+(\sqrt{15})^2=c^2$

Solve the exponents.

(7)²= 7*7=49

$49+ (\sqrt{15})^2=c^2$

(√15)²=√15*√15=15

$49+15=c^2$

Add.

$64=c^2$

Since we are solving for c, we must isolate the variable. It is being squared and the inverse of a square is the square root. Take the square root of both sides.

$\sqrt{64}=\sqrt{c^2} \\\sqrt{64}= c\\8=c$

The third side length is 8.

Write kkkkknn in exponenential form

horrorfan [7]

I count five 'k's there, so that part of the expression is

k⁵ .

Two 'n's form the rest of it, so that part is n² .

The parts are multiplied, so the simplest form of the expression is

k⁵ n² .
