I think you mean to say "hypotenuse". If so, then use the pythagorean theorem to get the following

a^2 + b^2 = c^2

16^2 + 20^2 = c^2

256 + 400 = c^2

656 = c^2

c^2 = 656

c = sqrt(656)

c = sqrt(16*41)

c = sqrt(16)*sqrt(41)

c = 4*sqrt(41)

The hypotenuse is exactly 4*sqrt(41) units long

This is approximately 25.612 when you use your calculator.

What is the measure of angle 1?

frutty [35]

Sum of all the interior angles = (5-2)x180 = 540°
540 - 100 - 120 - 100 - 90 = 130°
So the last unknown angle in the polygon is 130°

Sum of all the adjacent angles on a straight line is 180°
Angle 1 = 180 - 130 = 50°

The news stations said that their polls showed that 9% of voters would vote in favor of passing the law 600 of the 6,342 voters

stealth61 [152]

No. 9% of 6,342 is 570.78. Rounded, it's close to 600, but not exact.

$7n \le 21$

Divide both sides by 7.

$n \le 3$

n must be less than or equal to 3. n can be 3 or any number under 3.

For example, n can be 1, 2, 3.

If the discriminant of a quadratic equation is equal to -9, which statement describes the roots?

Mice21 [21]

ANSWER

No real roots.

The roots are complex or imaginary.

EXPLANATION

The quadratic equation

$a {x}^{2} + bx + c = 0$

has discriminant,

$D = {b}^{2} - 4ac$

If the discriminant is less than zero , then the quadratic equation has no real roots.

The given discriminant is -9.

Since -9 is less than zero, it means the quadratic equation has complex or imaginary roots.
