Answer:
Pythagoras theorem.
hypotenuse²=base²+height²
(18)²=(11)²+h²
324=121+h
324 - 121 = h²
203=h²
[tex] \sqrt{203m} = height[/tex]
Evaluate:
-│-23│ = ____
Answer:
-23
Step-by-step explanation:
Using the absolute rule,
[tex]\left|-a\right|=a[/tex].
Therefore,
[tex]-|-23|=-23[/tex]
(It becomes 23 first, but then you stick the negative sign after)
What is the equation for a line with a slope of
4/5 and a y-intercept of (0,7)?
Answer:
y = 4/5x + 7
Step-by-step explanation:
Use the slope intercept form, y = mx + b, where m is the slope and b is the y intercept
Plug in the slope and y intercept value of 7 to create the equation
y = mx + b
y = 4/5x + 7
So, the equation of the line is y = 4/5x + 7
what is 31=xy+15? for segment addition
Answer:
x = 16/y
or
y =16/x
Step-by-step explanation:
31=xy+15
subtract 15 from both sides of the equation:
xy = 16
x = 16/y
or
y =16/x
Find X. Give your answer in the simplest form.
Answer: 8
Step-by-step explanation:
We can use trigonometry to solve this:
If we call the angle at the top Ф then x is the opposite and 8 is the adjacent
Therefore we use Tan to solve this:
Tan Ф = opposite/adjacent
Tan 45 = X/8
1 = X/8
8 x 1 = X
Therefore X = 8

Answer:
Step-by-step explanation:
Put the quadratic equation y=4x^2-24x+5 into vertex form by completing the square then state the coordinates of the vertex.
Answer:
(3, -31)
Step-by-step explanation:
Factor 4 out of the first two terms:
y=4x^2-24x+5 becomes y=4(x^2 - 6x) +5
Next, complete the square of (x^2 - 6x): It is x^2 - 6x + 9 - 9
Insert this into y=4(x^2 - 6x) +5 in place of x^2 - 6x:
y=4(x^2 - 6x) +5 => y=4(x^2 - 6x + 9 - 9) +5, or
y=4( (x - 3)^2 - 9 ) + 5, or
y = 4(x - 3)^2 - 36 + 5, or:
y = 4(x - 3)^2 - 31
Compare this to: y = a(x - h)^2 + k
We see that the coordinates of the vertex (h, k) are (3, -31), and that a = 4.

The sides of a cube are measured in whole centimeters. Which of the following could not be the cube's volume?
64 cm 3
125 cm 3
8 cm 3
100 cm 3
Answer:
100 cm³
Explanation
• 4³ or 4 × 4 × 4 = 64
• 5³ or 5 × 5 × 5 = 125
• 2³ or 2× 2 × 2 = 8
•10² or 10 × 10 = 100 ( it is in square not cubic)

Each base in this oblique prism is a right
triangle.
What is the volume of the figure?
Answer:
66 cm³
Step-by-step explanation:
Volume of the oblique prism = Area of the base× height
V = Area of the triangular base × height
V = (bh/2)H.................. Equation 1
Where V = Volume of the prism, b = bas of the triangle, h = height of the triangle, H = height of the prism.
From the diagram,
b = 3 cm, h = 4 cm, H = 11 cm.
Substitute these values into equation 1
V = [(3×4)/2]×11
V = 6×11
V = 66 cm³
Hence the volume of the oblique prism is 66 cm³

Jillian and Josie are trying to find the value of the function, 8x^4-12x^3+3x^2-7x+4 at x=-1. Jillian says the only way to find the answer is to plug in -1. Josie says, no, there is another way. Who is right? Justify your answer.
Answer:
Josie is correct.
Step-by-step explanation:
There are other ways of finding the value of the function at x = 1.
For example, one way would be graphing or using a graphing device to graph the function. Once graphed, looking for the y-value where x = 1 would also provide the answer.
x 2 +2x+y 2 =0 what is the center and radius of the circle?
Center = (-1,0) Radius= 1
when you complete the square your equation should look something like
(x²+2x+1) (y²+0) = 1.The 1 on the left side coming from (b/2)² which is (2/2)² which equals 1 and whatever you add to one side, you have to add to the other so when you add 0+1 you get the 1 on the right side. Then factor or use the (b/2) from earlier without the ² so you should get (x²+1) + (y²+0) = 1. Flip the sign so you have negative 1 and 0. For the radius, square the right side and of course, [tex]\sqrt{1}[/tex] is simply 1 so your radius is 1. A lot of 1's huh? lol at least it makes the operations nice and simple :)

The regulation height of a basketball hoop is 10 feet above the court floor. On a scale model of a basketball court the height of the hoop is 5 inches from the court floor. What is the scale of the model
Answer:
1 : 2
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
10 / 5 = 2
1 inch represent 2 feet

Michael buys a car for $14, 999. The tax rate is 6%. What is the total purchase price of the car?
Answer:
15898.94
Step-by-step explanation:
First find the amount the tax is
6% = 0.06
14999 * 0.06 = 899.94
Add the amount of tax to the total amount of the net price (the price before tax)
14999 + 899.94 = 15898.94
What is the length of the unknown leg in the right triangle
Given:
The figure of a right angle triangle, we hypotenuse [tex]\sqrt{113}[/tex] mi and perpendicular 9 mi.
To find:
The length of the unknown leg in the right triangle.
Solution:
According to the Pythagoras theorem,
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
Using Pythagoras theorem, we get
[tex](\sqrt{113})^2=(9)^2+a^2[/tex]
[tex]113=81+a^2[/tex]
[tex]113-81=a^2[/tex]
[tex]32=a^2[/tex]
Taking square root on both sides.
[tex]\sqrt{32}=a[/tex]
It is only positive because the side length cannot be negative.
The length of the unknown leg in the right triangle is [tex]\sqrt{32}[/tex] mi.
Therefore, the correct option is B.
