Answer:

B and F

Step-by-step explanation:

If we solve the equation $y^3=64$ , we get $y=\sqrt[3]{64}$ . Therefore, B and F are the only correct answers since $4^3=64$ and $\sqrt[3]{64}=4$

Is my answer correct or no? ---> show explanation & details if i am wrong!!!

Answer:

No, because the distance from the origin to point (7 , -7) is greater than the radius of the circle ⇒ 3rd answer

Step-by-step explanation:

From the graph of the circle

∵ The center of the circle F is at the origin

∴ F is (0 , 0)

∵ The circle passes through point (7 , 0)

- The length of the radius of the circle is the distance between

the center of the circle and a point on the circle

∴ r is the distance between points (0 , 0) and (7 , 0)

∴ $r=\sqrt{(7-0)^{2}+(0-0)^{2}}=\sqrt{49}=7$

∴ The length of the radius of the circle is 7 units

Let us find the distance between point (7 , -7) and the origin (0 , 0)

If the distance is equal to the radius of the circle, then the point is on the circle
If the distance is greater than the radius, then the point is outside the circle
If the distance is less than the radius, then the point is inside the circle

∵ The distance = $\sqrt{(7-0)^{2}+(-7-0)^{2}}=\sqrt{49+49}=\sqrt{98}=7\sqrt{2}$

∵ r = 7

∵ $7\sqrt{2}$ > 7

∴ The distance is greater than the radius of the circle

∴ Point (7 , -7) lies outside the circle

The correct answer is:

No, because the distance from the origin to point (7 , -7) is greater than the radius of the circle

Your answer is not correct, the correct answer is the 3rd answer

To subtract two rational expressions that have a common denominator, you simply _____ the numerators.

Gala2k [10]

The answer is subtract.

For example:

$\frac{3x^2 - 3}{x+2} - \frac{x^2+6}{x+2}$

$\frac{3x^2 - 3-x^2-6}{x+2}$

$\frac{2x^2-9}{x+2}$

Clay is flying a helicopter at an altitude of 400 feet in the air. Jason is diving 200 feet below the surface.

aliina [53]

Answer:

They are 600 feet apart from each other.

Step-by-step explanation:

Since Clay is 400 feet away from ground level, which is 0, that sums up to 400. And Jason is -200 below 0, but in this case it is only asking for how much they are apart, so the negative doesn't apply to this. Now all you need to do is 400+200, which gives you the answer of 600 feet.
