Answer:

Domain: [-4, 4]

Range: [-3, 5]

Function? No

Step-by-step explanation:

Domain is all x-values that can be inputted in the graph that returns an output.

Range is all y-values that are outputted when <em>x</em> is inputted.

A function has to pass the Vertical Line Test.

A baby pool is shaped like a short, wide cylinder and holds 37 ft3 of water. A medium pool measures 3 times the height and width
Darya [45]

To solve this problem you must apply the proccedure shown below:

1. You have that the baby pool holds 37ft^{3} and the medium pool measures three times the height and width of the baby pool and both have the shape of a cylinder. Then, you can use the formula for calculate the volume of a cylinder, which is:

V=\pi r^{2} h

Where r is the radius (the half of the width), and h is the height.

2. As the height and the width of the medium pool measure three times the height and width of the baby pool, you must multiply the radius and the heigh by 3, therefore, the volume of the medium pool (V2) is :

V2=\pi (3r)^{2} (3h)\\V2=27\pi r^{2} h\\ V2= 27V1\\ V2=999ft^{3}

The answer is: B. 999ft^{3}

Use the quadratic formula with a = 2, b = -5, and c = 1



x = -b ± sq rt b2 - 4ac
-------------------- <---------- Please note: sq rt is over entire expression of b^2 - 4ac
2a


x = - (-5) ± sq rt (-5)2 + 4(2)(1)
-------------------------------- <---------Please note: sq rt is over entire expression (-5)2 + 4(2)(1)
2(2)



x = 5 ± √17

Plzzzzzzzzzz I need help!
Natali [406]
Hey!!

here is your answer >>>

As we know, The formula for the length of a trinagle is

(1/2)(base)(height) !.

Height is 6/5 and area is 2/5, then what is the base, we will just have to substitute these values!.

which is ,

2/5 = (1/2)(base)(6/5)

2/5 = (base)(3/5)

base = (2/5)/(3/5)

base = (2/5)(5/3)

base = 2/3 ft!.

Hope my answer helps!

Answer:

  2)  x = 7

  3)  x = 5

Step-by-step explanation:

When a transversal crosses parallel lines, all of the acute angles are congruent, and all of the obtuse angles are congruent. When it crosses at right angle, all of the angles are right angles.

2) All of the angles are right angles.

  11x +13 = 90

  11x = 77 . . . . . . subtract 13

  x = 7 . . . . . . . divide by 11

__

3) The two marked angles are acute.

  16x = 80 . . . . the acute angles are congruent

  x = 5 . . . . . . divide by 16
