Mathematics
1 answer:
Slav-nsk [51]3 years ago
5 0

Answer:

C

Step-by-step explanation:

Let's find the area of each of the two circles.

First Circle:

The first circle has a diameter of 10 inches. That means the radius is 5 inches. So, its area is:

A=\pi r^2\\A=\pi (5)^2\\A=25\pi

Second Circle:

The second circle has a diameter twice that of the first. So, the diameter is 20 inches. This means that the radius is 10 inches. Find the area:

A=\pi r^2\\A=\pi (10)^2\\A=100\pi

Now, find the ratio between them by dividing:

\frac{\text{Smaller}}{\text{Larger}}=\frac{25\pi}{100\pi}

Simplify:

\frac{\text{Smaller}}{\text{Larger}}=\frac{1}{4}

1/4 is the same as 1:4

So, our answer is C      :)

Write an equation in point-slope form for the line through the given point with the given slope.
Lilit [14]

The correct answer is D) y + 1 = 4/3(x - 9)

In order to find this, simply take the point and the slope and plug into the base form of point-slope form.

y - y1 = m(x - x1)

Use the slope for m and the point for (x1, y1)

y + 1 = 4/3(x - 9)

Using the discriminant, determine the number of real solutions.
uranmaximum [27]

Answer:

  C.  two real solutions

Step-by-step explanation:

Your quadratic matches the form ...

  ax^2 +bx +c = 0

for the values a=2, b=7, c=-15.

The discriminant is ...

  d = b^2 -4ac

For your values of a, b, c, the discriminant value is ...

  d = 7^2 -4(2)(-15) = 169

The discriminant is positive, indicating there are two real solutions.

_____

When the discriminant is negative, there are no real solutions, only complex solutions.

When the discriminant is zero, there is one real solution.

__

This equation factors as (2x-3)(x+5) = 0 and has solutions x=3/2, x=-5.
