Which is an x-intercept of the continuous function in the table?

Airida [17]

we know that

The x-intercept is the value of the variable x when the value of the function is equal to zero

In the table we have

$(-1, 0)$ is a x-intercept, because

For $x=-1$ the value of the function is equal to zero

$(-6, 0)$ is a x-intercept, because

For $x=-6$ the value of the function is equal to zero

therefore

<u>the answer is</u>

the continuous function in the table has two x-intercepts

$(-1, 0)$

$(-6, 0)$

Workout the area of the quarter of a circle with a radius of 8

QveST [7]

Answer:

$16\pi$

Step-by-step explanation:

We need to find 1/4 of the area of a circle with a radius of 8

Let r be radius

Area of a circle = $r^{2} \pi$

Substitute r with 8

Area of a circle = $8^2\pi =64\pi$

Now, to find 1/4 of the area, we can create an equation $\frac{64\pi }{4}={16\pi$

The answer is $16\pi$

Hope this helps :)

Have a spectacular day!
