Write the Equation Parabola has a vertex at (2,5) and passes through the point (3,7)

Mathematics

spin [16.1K]2 years ago
6 0
Given a vetex (h,k) of a function parabola, the corresponding equation is:
f(x)=a(x-h)^2+k
With (h,k)=(2,5) we get the equation:
f(x)=a(x-2)^2+5
In order to find a, we use the  given point (3,7) like this:
7=a(3-2)^2+5\\7=a+5\\a=7-5=2
The equation is then:
f(x)=2(x-2)^2+5

a^2b^7

Step-by-step explanation:

dividing exponents is basically subtracting the top exponent by the bottom. So, 3 - 1 = 2, thus giving you a^2, and 9 - 2 = 7, giving you b^7

A ramp 17 1/2 feet in length rises to a loading platform that is 3 1/2 feet off the ground. Find the angle that the ramp makes w
faltersainse [42]

Answer:

The angle that the ramp makes with the ground is 11.54°

Step-by-step explanation:

From the image attached, we can see that the length of 17 1/2 ft corresponds to the hypotenuse in a right triangle, the length of 3 1/2 ft corresponds to the opposite side.

We can use the fact that the sin(θ) = \frac{Opposite}{Hypotenuse} to find the angle that the ramp makes with the ground.

sin(\theta)=\frac{3.5}{17.5}

The angle is equal to

\theta = sin^{-1}(\frac{3.5}{17.5} )\\\theta = 11.54\°
