What is the range of the cubic function f(x)=x^3-15

1 answer:

Nina [5.8K]2 years ago

B

The end behavior of a positive cubic function states that as x approaches infinity, y approaches infinity.

Similarly, as x approaches negative infinity, y approaches negative infinity.

This means that when written in interval notation, the range is (-inf, +inf).

Me.perez drove a total of 40 miles in 5 days she drove the same number of miles each day.how many miles did me.perez drive each

ahrayia [7]

Answer:

She drove 8 miles each day.

Step-by-step explanation:

Given that she drove equal number of miles in 5 days. So in order to find the number of miles in each days, you have to divide it by 5,

$5days = 40miles$

$1day = 40 \div 5$

$1day = 8miles$

The coordinates of the vertices of a rectangle are (−3, 4) , (7, 2) , (6, −3) , and (−4, −1) . What is the perimeter of the rect

ki77a [65]

Answrer

Find out the what is the perimeter of the rectangle .

To prove

Now as shown in the figure.

Name the coordinates as.

A(−3, 4) ,B (7, 2) , C(6, −3) , and D(−4, −1) .

In rectangle opposite sides are equal.

Thus

AB = DC

AD = BC

Formula

$Disatnce\ formula = \sqrt{(x_{2} - x_{1})^{2} +(y_{2} - y_{1})^{2}}$

Now the points A(−3, 4) and B(7, 2)

$AB = \sqrt{(7- (-3))^{2} +(2- 4)^{2}}$

$AB = \sqrt{(10)^{2} +(-2)^{2}}$

$AB = \sqrt{100+4}$

$AB = \sqrt{104}$

$AB = 2\sqrt{26}\units$

Thus

$CD= 2\sqrt{26}\units$

Now the points

A (−3, 4) , D (−4, −1)

$AD = \sqrt{(-4 - (-3))^{2} +(-1- 4)^{2}}$

$AD = \sqrt{(-1)^{2} +(-5)^{2}}$

$AD = \sqrt{1 + 25}$

$AD = \sqrt{26}\units$

Thus

$BC = \sqrt{26}\units$

Formula

Perimeter of rectangle = 2 (Length + Breadth)

Here

$Length = 2\sqrt{26}\ units$

$Breadth = \sqrt{26}\ units$

$Perimeter\ of\ rectangle = 2(2\sqrt{26} +\sqrt{26})$

$Perimeter\ of\ rectangle = 2(3\sqrt{26})$

$Perimeter\ of\ rectangle = 6\sqrt{26}$

$\sqrt{26} = 5.1 (Approx)$

$Perimeter\ of\ rectangle = 6\times 5.1$

Perimeter of a rectangle = 30.6 units.

Therefore the perimeter of a rectangle is 30.6 units.

Ava and Addison are saving for a new cell phone. Ava is starting with $100 and adding $5 each week. Addison is starting with $20

diamong [38]

Answer:

it takes 90 weeks for them to have the same amount of money saved which would be 600 dollars

Step-by-step explanation:

100 Addison 200 Ava

1. 10 weeks= $50 1. 10 weeks= $40

2. 10 weeks= $50 2. 10 weeks= $40

3. 10 weeks= $50 3. 10 weeks= $40

4. 10 weeks= $50 4. 10 weeks= $40

5. 10 weeks= $50 5. 10 weeks= $40

6. 10 weeks= $50 6. 10 weeks= $40

7. 10 weeks= $50 7. 10 weeks= $40

8. 10 weeks= $50 8. 10 weeks= $40

9. 10 weeks= $50 9. 10 weeks= $40

Equals $600 Equals $600

Hope this helps took me some time!
