Mathematics
1 answer:
Yanka [14]3 years ago
4 0

Answer:

A

Step-by-step explanation:

At the vertex, the quadratic term in this notation must be zero, i.e., the (x-1)  part. This happens for x=1. So you can already rule out answers C and D.

Now fill in x=-2 in both remaining answers and see what happens.

For A: y = -2(-2 - 1)² + 3 = -15

For B: y = (-2 - 1)² + 3 = 12

That eliminates B and leaves A.

A number is 6 times another number and their difference is 30. What are the numbers? ​
Alenkasestr [34]

Answer:

x=36

y=6

Step-by-step explanation:

Let the numbers be x and y

Condition 1

x=6y ----------(1)

Condition 2

x-y=30 ------------(2)

Putting 1 in 2

6y-y=30

5y=30

Dividing both sides by 5

y=6

Now

Putting y=6 in 1

We get

x=6(6)

x=36

The shaded sector above covers 1/3 of the circle. If the radius of the circle above is 3 cm, what is the area of the sector in t
Mekhanik [1.2K]

Given:

The shaded sector above covers \dfrac{1}{3} of the circle.

Radius of the circle = 3 cm

To find:

The area of the sector in terms of π.

Solution:

The area of a circle is

A=\pi r^2

Substituting r=3, we get

A=\pi (3)^2

A=9\pi

It is given that the shaded sector above covers \dfrac{1}{3} of the circle.

The area of shaded sector =\dfrac{1}{3}A

                                             =\dfrac{1}{3}(9\pi)

                                             =3\pi

Therefore, the area of shaded sector is 3π sq. cm.

HELP NEEDED ASAP!! Amani computed in a two-way table the relative frequencies of sales of homes listed with two different real e
guajiro [1.7K]
The answer is c.

When you look at the data, in the first column, the frequency of sales of both are similar. Even the second column shows similar data. Association is determined if there is a significant difference between the data in each column/row depending on what you are aiming to answer.

In this case, we look at it per column because you want to compare the frequencies of sales of each company which are aligned by columns. So we know to look at the columns and not the rows.
