plz answer quickly

Answer:

A. [tex]4^3*6^3[/tex]

Step-by-step explanation:

First, you solve the given equation.

[tex](4*6)^3\\\\=24^3\\=13824[/tex]

You solve the multiple choice afterwards. Since choice A was given first, we managed to find the answer.

[tex]4^3 * 6^3\\\\=64 * 216\\=13824[/tex]

Choice A has the same answer as the given equation, making them equivalent.

Answer:3

7

−

3

6

–6

Step-by-step explanation:

x = 6 and x = -2

Step-by-step explanation:

Put the 12 to the other side

x^2 - 4x - 12 = 0

Now factor this out:

(x - 6)(x + 2) = 0

Therefore, the roots of this equation are

x = 6 and x = -2

Answer:

Answer:

3rd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the rate of change and c the y- intercept )

Given

2x + 8y = - 4 ( subtract 2x from both sides )

8y = - 2x - 4 ( divide terms by 8 )

y = - [tex]\frac{2}{8}[/tex] x - [tex]\frac{4}{8}[/tex] , that is

y = - [tex]\frac{1}{4}[/tex] x - [tex]\frac{1}{2}[/tex] ← in slope- intercept form

with rate of change m = - [tex]\frac{1}{4}[/tex] and y- intercept c = - [tex]\frac{1}{2}[/tex]

Answer:

16

Step-by-step explanation:

Shape C is A trapezoid

Area of trapezoid = [tex]\frac{a+b}{2} h[/tex]

where a and b =  base lengths and h = height

The trapezoid has the following dimensions

base 1 = 3 units

base 2 = 5 units

height = 4 units

Using these dimensions we plug in the values into the formula stated above.

[tex]A=\frac{3+5}{2} 4\\3+5=8\\\frac{8}{2} =4\\4*4=16[/tex]

Hence the area of shape C = 16 square units

Answer:

rectangle A's area: 12, 3 x 4 = 12

Area b: 1 x 4 = 4 divided by 2 = 2, the base is 1 height is 4. Multiply given lengths, then multiply by 1/2 because formula of a triangle is BH x 1/2. To get your answer of 2.

Area C: 3 + 5 = 8, 8 x 4 = 32, 32 divided by 2 = 16, formula of a trapezoid is base 1 + base 2 x height x 1/2. In this case 5 is your base and base 2 is 3. Add them up to get 8. We then multiply 8 by the height which is 4 if you count from the top to bottom in the middle. 8 x 4 = 32. 32 x 1/2 = 16 (basically just dividing by 2).

Answer:

x = 35

C = 18.92

A = 71.07

Step-by-step explanation:

x)

Use the Pythagorean theorem to find the unknown side.

[tex]a^{2} +b^{2} =c^{2} \\\\\\12^{2} +x^{2} =37^{2} \\x^{2} = 37^{2}-12^{2}\\x=35[/tex]

For Angle C

The angle C can be found using the inverse sine function.

C=arcsin(opp/hyp)

C=arcsin(12/37)

C=18.92

For Angle A

The sum of all the angles in a triangle is 180 degrees.

A + 90 + 18.92 = 180

A = 71.07

Answer:

0.4 , 0.1

Step-by-step explanation:

Let number of boys be = b , number of girls = b + 4 . As total students = 20    b + b + 4 = 20  → 2b + 4 = 20 → 2b = 20 - 4 = 16 → b = 16 / 2 = 8 (boys) , so girls = 12

Prob (a random first child is a boy) = boys / total students = 8 c 1 / 20 c1, or =  8  / 20  = 0.4

Prob ( a 'Tina' out of two Tina is the last) = 2 c 1 / 20 c 1 , or = 2 / 20 = 0.1

Answer:

D, 245.0 in^2

Step-by-step explanation:

Formula for the surface area of a cylinder: A=2πrh+2πr^2

A = 2πrh + 2πr^2

A = 2π(3)(10) + 2π(3)^2

A = 60π + 18π  

A = 245.044
