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
For the right triangle shown, use the trig functions to find the value of x. Round your answer to the nearest tenth.

2. 8.2
3. 9.4
4. 7
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/adjacentTheta (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

what is a preimage and image of triangle in a translation
Answer:
translation to what language?
Step-by-step explanation:
9514 1404 393
Explanation:
The preimage is the original triangle, the figure before any transformation is done to it.
The image is the result of applying a transformation to the preimage.
__
When the transformation is translation, the image is congruent to the preimage, but is located in a different place. It is not rotated or reflected if the only transform is translation.

Step-by-step explanation:
Rise= ?
Run= ?
Slope= ?
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.

24.39 is 9% of what number..........................
Answer:
271
9 percent (calculated percentage %) of what number equals 24.39? Answer: 271.
Step-by-step explanation:
Answer:
2.19 I think. Hopefully this helps. You first turn 9% into a decimal, which is 0.09. Then multiply by 24.39, which is 2.19. You can also use the friendly percentage, 10%.
I don't know if this is correct because I'm not too sure, but I hope this helps.

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)
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.
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
