Find the equation of a circle that has its center at (-4, 3) and has a radius of 5. (x + 4) 2 + (y - 3) 2 = 25

Andreas93 [3]

Answer:

$(x+4)^2 + (y-3)^2 = 25$

Step-by-step explanation:

You can use the center of a circle to write an equation in vertex form. Vertex form is $(x-h)^2+(y-k)^2 = r^2$ and the vertex is (h,k). Notice (h,k) are the opposite sign in the equation then as the point.

Here h = -4 and k = 3. Substitute these values and the value r = 5.

$(x--4)^2 + (y-3)^2 = 5^2\\(x+4)^2 + (y-3)^2 = 25$

Waheeda wants to buy a skateboard. She has $15 in savings. A skateboard costs $75. How much more money does she need? Write and

erica [24]

Answer and Explanation:

Suppose Waheeda needs x more dollars.

Right now, she has $15. She needs x more, so we add x to 15. The end result we hope to have is $75. So, the equation is:

x + 15 = 75

To solve, we simply subtract 15 from both sides: x = 75 - 15 = 60

Thus, she still needs $60.

Hope this helps!

4)What kind of shape do the parametric equations make?X= 7sin(theta), y= 2cos(theta)

Monica [59]

Answer:

Ellipse

Step-by-step explanation:

Given

$x = 7sin\theta$

$y= 2cos\theta$

Required

The kind of shapes with such equations

This answer to this question is(B) Ellipse

The parametric equation of an ellipse is represented as:

$x = asin(\theta)$ and $y = bcos(\theta)$

In this case:

$a=7\ b = 2$

So:

$x = 7sin\theta$ and $y= 2cos\theta$

If h(x) = (fºg)(x) and h(x) = 3(x+2)^2 find one possibility for f (x) and g(x).

JulsSmile [24]

Answer:

$f(x) = 3x^2$

$g(x) = x + 2$

Step-by-step explanation:

Given

$h(x) = 3(x+2)^2$

$h(x) = (fog)(x)$

Required

Find f(x) and g(x)

$h(x) = (fog)(x)$

Rewrite h(x)

$h(x) = f(g(x))$

If $h(x) = 3(x+2)^2$

then

$f(g(x)) = 3(x+2)^2$

This implies that; the expression in the brackets are equal;

In other words; function g(x) on the left hand side is equal to expression x + 2 on the right hand side

So;

$g(x) = x + 2$

To find f(x), substitute g(x) with x

$f(x) = 3(x)^2$

$f(x) = 3x^2$

Final solutions are

$f(x) = 3x^2$

$g(x) = x + 2$
