Find the zero of the function.
f(x)= 4x^2– 12x+9

Answers

Answer 1

Answer:

The zero is x = 3/2 = 1.5

Step-by-step explanation:

We recognize that the trinomial  4 x^2 - 12 x + 9 is a perfect square trinomial, which comes from the following squared binomial:

(2 x - 3)^2

Therefore, the zeros are the x-values that verify the following:

(2 x - 3)^2= 0

that is   (2 x - 3) = 0 and solving for "x":

2 x = 3

x = 3 / 2

x = 1.5

Step-by-step explanation:

Rise= ?
Run= ?
Slope= ?

Answers

Answer:

Rise = 0

Run = 4

Slope = 0

Step-by-step explanation:

Slope of straight line = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

Since, given line is passing through two points (-2, -3) and (2, -3),

Rise of the line = -3 - (-3) = 0

Run of the given line = 2 - (-2) = 4

By substituting these values of rise and run in the formula,

Slope = [tex]\frac{0}{4}[/tex]

          = 0

Therefore, Rise = 0

                  Run = 4

                 Slope = 0

Note:  Slope of a line parallel to the x-axis is zero.

           Slope of a line parallel to y-axis is not defined.

Answer:

[tex]\boxed{\boxed {\sf 3. \ 9.4}}[/tex]

Step-by-step explanation:

First, recall the three basic right triangle trigonometry ratios.

sin(θ)=opposite/hypotenuse cos(θ)= adjacent/hypotenuse tan(θ)= opposite/adjacent

Theta (θ) represents the angle. The angle (other than the right angle) is 70 degrees.

We are also given 2 sides: 10 and x.

10 is the hypotenuse, because it is opposite the right angle. x is opposite the 70 degree angle.

Since we have the opposite and hypotenuse, we must use sine.

[tex]sin (\Theta)= \frac{opposite}{hypotenuse}}[/tex]

The angle is 70 degrees, the opposite is x, and the hypotenuse is 10.

[tex]sin(70)=\frac{x}{10}[/tex]

We are solving for x. We must isolate x on one side of the equation.

Currently, x is being divided by 10. To "undo" the division, we must perform the inverse operation, which is multiplication. Multiply both sides of the equation by 10.

[tex]10*sin(70)=\frac{x}{10}*10[/tex]

[tex]10*sin(70)=x[/tex]

[tex]10*0.939692621=x[/tex]

[tex]9.39692621=x[/tex]

Round to the nearest tenth. The 9 in the hundredth place tells us to round the 3 up to a 4.

[tex]9.4 \approx x[/tex]

x is about 9.4

Point R on the coordinate grid below shows the location of a car in a parking lot. A second car needs to park 6 units above R to leave room for a utility truck. What are the coordinates of the location of the second car?

Image of a coordinate grid with point R R located at negative 1, negative 3.
(3 points)

(−1, −3)
(−1, 3)
(5, −3)
(5, 3)

Answers

Answer:

Point R is located at the point (-1,-3)

The car needs to park 6 units above point R.

When you are moving something up or down on the coordinate grid, you are affecting the y- axis. So to find the coordinates we would keep the x value and add 6 to the y value.

Coordinates of the second car

(-1, -3 +6)

(-1 , 3)

The answer to this question is B

Adding a positive to a negative is the same as subtracting.

EX:

We were adding 6 and -3

Adding 6 and -3 is the same as subtracting 3 from 6.

Either way we get the same answer.

B is your answer

Find the volume of a right circular cone that has a height of 11.1 in and a base with a
circumference of 17.6 in. Round your answer to the nearest tenth of a cubic inch.

Answers

Answer:

V = 0.8 in^3

Step-by-step explanation:

Formula:

V = πr^2(h/3)

C = 2πr

Given:

h=11.1

C = 17.6

C = 2πr

17.6 = 22πr

0.8/π = r

V = πr^2(h/3)

V = π(0.8/π)^2((11.1)/3)

V = π(0.0648455575)(3.7)

V = 0.8 in^3

40:10 = 12 :
Equivalent ratio

Answers

40:10=12:3


Solution:

Since
40 : 10 = 12 : X

Then we know
10/40 = X/12

Multiplying both sides by 12 cancels on the right
12 × (10/40) = (X/12) × 12
12 × (10/40) = X

Then solving for X
X = 12 × (10/40)
X = 3

Therefore
40 : 10 = 12 : 3
