describe the relationship between the zeros of the quadratic function and linear factors of the expression
Answer:
F(x) represents the zeros of the given quadratic function. i.e. the linear factors represents zero when we resolve the expression
Step-by-step explanation:
Describing the relationship between the zeros of the quadratic function and the linear factors of the expression using an example as shown below
lets describe this using the example below :
quadratic expression : F(x) = ax^2 + bx + c
let the linear factors of F( x ) = 0
F(x) represents the zeros of the given quadratic function above i.e. the linear factors represents zero when we resolve the expression
Help! Solve for the value of x.
Answer:
x=6 degrees
Step-by-step explanation:
I know that 31+(10x-1)=90. Then I have to subtract 31 from 90 to get 10x -1.
That's 59. I solve for x in the equation 59=10x-1.
That is the same thing as 60=10x, which is also the same as 6=x.

Solve the inequality for u.
-10 ≤ - 5u
Simplify your answer as much as possible.
Answer:
u ≤ 2
Step-by-step explanation:
Given
- 10 ≤ - 5u
Divide both sides by - 5 , reversing the symbol as a result of dividing by a negative quantity.
2 ≥ u , then
u ≤ 2
You and your family went to Texas Roadhouse for dinner. Your check was $89.25. If you left the waitstaff 20%, how much was your total bill?
Answer:

Circle geometryCircle geometry are made up of lines and angles
From the given diagram, the sum of angles on the straight line GKH is 180 degrees
arcGM + arcMN = 180 degrees
Given that arcMN = 90 degrees, hence;
arcGm = 180 - 90
arcGM = 90 degrees
Hence the measure of the angle arcGM is 90degrees

To the nearest tenth, what is the length of QR
Answer:
|QR| = 17.6
Step-by-step explanation:
To answer this we need to show that the triangles are similar or to assume that they are similar.
Note the following:
1. The ratio of the longest sides is 12.5 to 25.0, or 1/2;
2. The ratio of the shortest sides is 5.2 to 10.4, or 1/2
Therefore the ratio of the longer legs is 8.8 to QR, also equal to 1/2
8.8 1
-------- = -----
QR 2
Cross-multiplying, we get |QR| = 17.6
Answer:
[tex] \displaystyle B )\overline{ \text{QR }}= 17.6 cm[/tex]
Step-by-step explanation:
we have two similar triangles
we want to figure out the measure of QR
remember that,
the ratio of the corresponding sides of two similar triangles is equal
thus,
[tex] \displaystyle \frac{8 .8}{QR} = \frac{5.2}{10.4} [/tex]
cross multiplication:
[tex] \displaystyle5.2 QR = 91.52[/tex]
divide both sides by 5.2:
[tex] \displaystyle \frac{5.2 QR }{5.2}= \frac{ 9 1.52}{5.2}[/tex]
simplify division:
[tex] \displaystyle QR = 17.6 cm[/tex]
hence, our answer is B

inches. The cone has a radius of 3 inches. What is the height of the cone?
Show your work.
Plz help
Answer: 4 in
Step-by-step explanation:
The volume of the cylinder is
[tex]V=(\pi)(2^{2})(3)=12\pi[/tex]
If we let the height of the cone h, the volume of the cone is
[tex]V=\frac{1}{3}(\pi)(3^{2})(h)=3\pi h[/tex]
Setting these volumes equal,
[tex]12\pi=3\pi h\\\\12=3h\\\\h=\boxed{4 \text{ in}}[/tex]
