You can model an arch at your school using the equation $y=-0.5\left(x+4\right)\left(x-4\right)$ , where $x$ and $y$ are measured in feet. The x-axis represents the ground. Find the width of the arch at ground level.
Answer:
8feet
Step-by-step explanation:
Given the equation that models the arch of a school expressed as;
[tex]$y=-0.5\left(x+4\right)\left(x-4\right)$[/tex]
If the x axis represents the ground;
At the ground level, x = 0
Substitute x = 0 into the equation to get y;
y = -0.5(0+4)(0-4)
y = -0.5(4)(-4)
y = -0.5 * -16
y = 8ft
Hence the y axis at the ground level is 8feet
Pythagoras Theorem
A. x=5
B. x=2square root of 1
C. x=square root of 34
D. x=2square root of 61
9514 1404 393
Answer:
B. x = 2√11
Step-by-step explanation:
The square of the length of the diagonal is ...
d² = 6² + 8² = 36 +64 = 100
Then the length of x is found from ...
d² +x² = 12²
x² = 144 -100 = 44 . . . . . subtract d²
x = √44 . . . . . . take the square root
x = 2√11
Draw the graph of the equation
g(x) = -3x +2.
You can refer to the section "Drawing Graphs in Mobius" in the unit "Introduction to
Mobius" for
practice in drawing graphs of lines in Mobius.
Part a: Find one point on the line. Often it's smart to start with the value x = 0 because multiplying by
and adding 0 are easy. In other words, find the y-intercept.
The point (0, Number ) is on the line g(x) = -3x + 2.
Part b: Find a second point on the line. Often it's easier to continue with the value x = 1 as multiplying
by and adding 1 are pretty easy.
The point (1, Number ) is on the line g(x) = -3x +2.
Use DESMOS to graph any function online.
The picture shows the graph of g(x) = -3x + 2.

please I need help
Answer:
n = -6
Step-by-step explanation:
n -12 = 3n
2n = -12
n = -6
Answer:
n=-6
Step-by-step explanation:
So first, you should subtract n from both sides to isolate the number -12. This will make the equation look like 2n=-12. Divide both sides by 2 because you want n to be by itself. This will give you the answer n=-6

What do I do in this problem?
Answer: p=60
Step-by-step explanation:
Angles on a straight line always add up to 180 degrees.
So, because you have an angle on the straight line with the arrow going up, you have to do:
180-110=70
This will give you the angle inside of the triangle that is next to 110.
Then you would find the angle next to 130 (using the horizontal line) by using the same method so you would do:
180-130=50
This gives you the angle inside the triangle next to 130.
Then because a triangle always adds up to 180 you would add up the 2 angles you have figured out like this:
70+50=120
Then you would take the answer away from 180 like this:
180-120=60
So, p=60
Hope this helps :)

Tanner and Zach both play basketball. In a game, Tanner scored six points. Zach scored four times as many times as Tanner. How many points did Zach score?
Answer:
24
Step-by-step explanation:
Tanner has 6 points so T = 6
Zach has four times as many so Z = 4T
4 * T

If a triangle has A as 4 and B as 13, but C, the hypotenuse, is missing, what is C? I already got to square root of 185 but i don't understand what to do because you can't simplify it, please show your work/explain it
Answer:
C = √185 or 13.6 units.
and cannot be simplified any further because it is irrational.
Step-by-step explanation:
Since the triangle has sides A = 4 units and B = 13 units. With C as its hypotenuse side, from Pythagoras' theorem C² = A² + B².
So, substituting A and B into the equation, we have
C² = 4² + 13²
C² = 16 + 169
C² = 185
taking square root of both sides, we have
√C² = √185
C = √185
C cannot be simplified any further because it is irrational. It is best expressed as √185 which is a surd. C could also be expressed as a decimal. So using your calculator and taking √185, C = √185 = 13.605 ≅ 13.6 units.

The area of a rectangular dance floor is 8 1/4
square yards, and its width is 3 1/2 yards. What is the patio's length in yards
A 54
B 2
C 4:
D 5
Answer:
2 5/14 yards
Step-by-step explanation:
Area of the rectangular floor = Length * Width
Given
Area = 8 1/4 square yards
width = 3
1/2 yards
Required
Length
Length = Area/width
Length = (8 1/4)/(3 1/2)
Length = 33/4 ÷ 7/2
Length = 33/4 * 2/7
Length = 33/14
length = 2 5/14 yards
This gives the required length

Answer:
5 and 100
8 and 160
9 and 180
12 and 240
Step-by-step explanation:
Since for every one sweatshirt there is $20 collected. Simply plug this in and do the multiplication and division.
5x20 = 100
8x20 = 160
180/20 = 9
12x20 = 240
Answer:
3, 5, 8, 9, 12
60, 100, 160, 180, 240
Step-by-step explanation: the only values that you have full information for is the first column
3, 60
to get from 3 to 60 you would multiply by 20, so for the next column multiply 5 by 20 to get 100
then 8, 160
for the fourth column you would just divide 180 by 20, 9
and finally for the last column you would multiply 12 by 20 to get
240

A cone shaped party hat has a radius of 3 inches and a height of 6.5 inches. Find the number of cubic units that hat occupies?
Answer:
61.25
Step-by-step explanation:
The of cubic units which hat occupies having a radius of 3 inches and a height of 6.5 inches is 61.26 cubic inches.
What is of volume of cone?Volume of cone is the amount of quantity, which is obtained it in the 3 dimensional space.
The volume of the cone can be given as,
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Here, (r) is the radius of the base of the cone and (h) is the height of the cone.
A cone-shaped party hat has a radius of r=3 inches and a height of h=6.5 inches. The amount of cubic units it occupies is equal to the volume of hat.
Thus, put the values in the above formula as,
[tex]V=\dfrac{1}{3}\pi (3)^2(6.5)\\V=\dfrac{1}{3}\pi (3)^2(6.5)\\V=61.26\rm\; in^3[/tex]
Thus, the of cubic units which hat occupies having a radius of 3 inches and a height of 6.5 inches is 61.26 cubic inches.
