If f(x)=x^2-2x+11, find f (-2)
Answer: f( -2) = 19
Step-by-step explanation:
plug '-2' into every place 'x' is in
so the new equation would be
f(-2) = (-2)^2 - 2(-2) + 11
and now solve :)
f ( -2) = 4 - ( -4) + 11
f (-2) = 4 + 4 + 11
f ( -2 ) = 19
Glenn has a garden that is shaped like a rectangle.
The perimeter of his garden is 7012 feet.
The length of the garden is 2434 feet.
What is the width of the garden?
21 ft o 11ft o 10 ½ ft o 45 ¾ ft
Answer:
Solution given:
The length of the garden[l] = 2434 feet.
breadth or width [b]=b
perimeter of his garden = 7012 feet.
2[l+b]=7012ft
2434+b=7012/2
b=3506-2434
b=1072
So the width of the garden is 1072ft.

Find the circumference and area of each circle. Include the formula thank you
Answer:
Circumference: 50.27 cm
Area: 201.06 cm²
Step-by-step explanation:
Hi there!
1) Determine the circumference
[tex]C=\pi d[/tex] where d is the diameter of the circle
Plug in the diameter (16 cm)
[tex]C=16\pi\\C=50.27[/tex]
Therefore, the circumference is 50.27 cm when rounded to the nearest hundredth.
2) Determine the area
[tex]A=\pi r^2[/tex] where r is the radius
Plug in the radius (16/2=8)
[tex]A=\pi (8)^2\\A=64\pi\\A=201.06[/tex]
Therefore, the area of the circle is 201.06 cm² when rounded to the nearest hundredth.
I hope this helps!

someone helpp asap plss
Answer:
A. A single fixed point that is half the distance from the parabola as the direction is from the paranola
A single fixed point that is half the distance from the parabola as
the directrix is from the parabola. Therefore, option A is the correct answer.
What is the parabola?A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola.
A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix. The focus lies on the axis of symmetry of the parabola.
Therefore, option A is the correct answer.

If we dcrease the radius of each cylinder by 2m , which one has the greater volume give your answer rounded to the nearest tenth use 3.14 for pi
Answer:
See Explanation
Step-by-step explanation:
Given
The question is incomplete, as the cylinders are not given.
Required
The cylinder with greater volume
To answer this question, I will assume the following dimensions.
Cylinder 1
[tex]r = 5[/tex]
[tex]h = 10[/tex]
Cylinder 2
[tex]r = 7[/tex]
[tex]h = 5[/tex]
Volume is calculated as:
[tex]V = \pi r^2h[/tex]
When the radius is reduced by 2, the formula becomes
[tex]V = \pi (r - 2)^2h[/tex]
For the first cylinder, we have:
[tex]V_1 = \pi (r - 2)^2h[/tex]
[tex]V_1 = 3.14 * (5 - 2)^2 * 10[/tex]
[tex]V_1 = 3.14 * 3^2 * 10[/tex]
[tex]V_1 = 3.14 * 9 * 10\\[/tex]
[tex]V_1 = 282.6[/tex]
For the second cylinder, we have:
[tex]V_2 = \pi (r - 2)^2h[/tex]
[tex]V_2 = 3.14 * (7 - 2)^2 * 5[/tex]
[tex]V_2 = 3.14 * 5^2 * 5[/tex]
[tex]V_2 = 3.14 * 25 * 5[/tex]
[tex]V_2 = 392.5[/tex]
Cylinder 2 has a greater volume because 392.5 > 282.6
Note: Irrespective of the dimension of the cylinders, the above step works fine.

Which measure of center is best to use to determine the expected number of strokes required for the ninth hole? The mean is the best choice because the data is nearly symmetrical. The median is the best choice because data is clustered. The mean is the best choice because the data is skewed to the right. The median is the best choice because the data is skewed to the left.
Answer:
The mean is the best choice because the data is nearly symmetrical
Step-by-step explanation:
Question:
The data from the dot plot obtained from another post of the question are;
[tex]\begin{array}{ccc}Strokes \ Required&& Number \ of \ Players\\1&&2\\2&&3\\3&&4\\4&&5\\5&&5\\6&&3\\7&&2\\8&&\\9&&1\end{array}#[/tex]
From the given data, we have that the mean of the 25 players is 4.24
Mean = 4.24 strokes
The median strokes is 4.5 strokes
Median = 4.5
The values of the mean and median are approximately equal because the data are symmetrical and has the normal shape
Therefore, the mean is the best option due to the symmetrical shape of the data.
Answer:
A) The mean is the best choice because the data is nearly symmetrical

Which line has the greatest slope?
Answer:
Line B
Step-by-step explanation:
Automatically, we can eliminate Line C, because the slope is negative, since the question's asking which one is the greatest slope. However, if you do want to find the slope of Line C, you can use the rise/run method or the slope formula. Using the coordinate sets (0, 0) and (1, -2) and applying y2-y1/x2-x1 = -2-0/1-0 = -2/1 = -2.Line A's slope is 1/2. You can either find this out by applying the rise/run formula (rise = 1, run = 2) or you can find 2 coordinate sets to solve for slope. In this case, I'll use (0, 0) and (2, 1). Using the formula y2-y1/x2-x1... 1-0/2-0 = 1/2.Line B's slope is 2. As stated in Line A, you can find this by applying the rise/run formula or using 2 coordinate sets. I'll use the points (0, 0) and (1, 2). Using the formula y2-y1/x2-x1... 2-0/1-0 = 2/1 = 2.Since the question is asking which line has the greatest slope, the line that has the greatest slope would be Line B. (2 > 1/2 > -2)

Answer:
Q1: 18 degrees
Q2: 60 sides
Step-by-step explanation:
The sum of the exterior angles is always 360 degrees. With this, do 360/20 to get the amount of sides that are within the shape.
360/20 --> 18 degrees.
Now with the interior angles, it can be found with the equation ((n-2) * 180 degrees) / n = Angle Given. With this, plug 174 degres into your equation.
(n-2) * 180 degrees) / n = Angle Given
(n-2) * 180 degrees) / n = 174
180n -360 / n = 174
180n -360 / 174n
360 = 6n
n = 60
It would be 60 sides.
What is y=4x+13
y=6x+19
Must show work
Answer:
x= -3
y= 1
Step-by-step explanation:
y=4x+13
y=6x+19
put them equal to each other
4x+13=6x+19
subtract 4x from each side
13=2x+19
subtract 19 from both sides
-6 = 2x
divide by 2
x= -3
plug x into one of the equations
y=4x+13
y=4(-3)+13
y= -12+13
y= 1
