The slope will be 2 because you subtract 1-(-7) which are your y-axis and then subtract 3-(-1)which are your x-axis. which ends up with 8/4. Simplify and you get 2

What is the relationship between the length of one leg and the length of the hypotenuse of an isosceles right triangles?

Ipatiy [6.2K]

Answer:

B) Hypotenuse = Leg ∙ √2

Step-by-step explanation:

This is a well-known ratio in the 45-45-90 right triangle, but we can derive it.

An isosceles right triangle has two congruent legs forming the right angle and the hypotenuse opposite the right angle. The Pythagorean theorem works since it is a right angle.

Normally, the legs are a and b, and the hypotenuse is c, and we have

a^2 + b^2 = c^2

Here the legs are congruent, so we have a = b.

Substituting a for b, we have

a^2 + a^2 = c^2

2a^2 = c^2

c^2 = 2a^2

c = a√2

Answer: B) Hypotenuse = Leg ∙ √2

How much leather is needed to cover a basketball with a diameter of 14 inches?

Zinaida [17]

Answer:

43.96 inches

Step-by-step explanation:

The formula for finding circumference is: 3.14*d(diameter). So if you plug in the 14 in the equation, you get 3.14*14 which is what I did to get the answer.

Hope this helped, mark brainliest and thanks! Have an awesome day! ;D

How do i solve this for g(-3)?

Advocard [28]

Answer: g(-3) is 9 .

Step-by-step explanation:

So there are two functions and the first function says that to get the solution x has to be greater than 4 and -3 which is the input is not greater than 4 so you can't use that function to solve for g(-3).

using the second function , it says that x has to be less or equal to 4. And -3 is indeed less than 4 so you have to use the second function to solve for g(-3)

g(x) = -2x + 3 Input -3 and solve

g(-3) = -2(-3) + 3

g(-3) = 6 + 3

g(-3) = 9

What is the slope of the line tangent to the curve y+2 = (x^2/2) - 2siny at the point (2,0)?

Aleksandr-060686 [28]

Implicit differentiation
take the deritivive with respect to x

first
y+2=(1/2)(x^2)-2sin(y)
take deritivitive
dy/dx+0=1/2(2x)-2(cosy)dy/dx
dy/dx=x-2cosy(dy/dx)
add 2cosy(dy/dx) to both sides
dy/dx+2cosy(dy/dx) =x
undistribute dy/dx
dy/dx(1+2cos(y))=x
divide both sides by 1+2cos(y)
$\frac{dy}{dx}= \frac{x}{1+2cos(y)}$
at (2,0)
x=2
y=0

$\frac{dy}{dx}= \frac{2}{1+2cos(0)}$
$\frac{dy}{dx}= \frac{2}{1+2(1)}$
$\frac{dy}{dx}= \frac{2}{1+2}$
$\frac{dy}{dx}= \frac{2}{3}$
the slope is 2/3

The standard deviation of a normal random variable x is $20. given that p(x ≤ $10) = 0.1841. from this we can determine that the

attashe74 [19]

Let $\mu$ be the mean of $X$ . Then

$\mathbb P(X\le10)=0.1841\iff\mathbb P\left(\underbrace{\dfrac{X-\mu}{20}}_Z\le\dfrac{10-\mu}{20}\right)=0.1841$

For a random variable $Z$ following the standard normal distribution, we have

$\mathbb P(Z\le z)=0.1841\implies z\approx-0.8999$

Transform the random variable to get this critical value in terms of $\mu$ :

$\dfrac{10-\mu}{20}=-0.8999\implies\mu\approx27.997$
