If f(x)=-2x^2+5x-3 and g(x) is the reflection of f(x) across the y-axis, then an equation of g is which of the following
Ymorist [56]

To reflect a function across the y-axis you have to change

x\mapsto -x

So, the function becomes

f(x)=-2x^2+5x-3 \mapsto f(-x)=-2(-x)^2+5(-x)-3=-2x^2-5-3

What is the measure in degrees for the central angle of a circle whose radius is 9 cm and intercepted arc length is 7.2 cm?
Marina CMI [18]

Answer:

Therefore the measure of the central angle is 45.86°.

Step-by-step explanation:

Given:

Radius = 9 cm

arc length = 7.2 cm

pi = 3.14

To Find:

Central angle = θ =?

Solution:

If the θ  measured in degree then the arc length is given as

\textrm{arc lenght}=\dfrac{\theta}{360\°}\times 2\pi r

Where r = radius, θ = Central angle

On substituting the values we get

7.2=\dfrac{\theta}{360}\times 2\times 3.14\times 9\\\\\theta=\dfrac{2592}{56.52}=45.8598=45.86\\\therefore \theta=45.86\°

Therefore the measure of the central angle is 45.86°.
