Answer:

Use fraction multiplication

Step-by-step explanation:

It isn't to hard just lok at some notes and don't let a calculaotr mess you up.

Add to the starting height or use slope, y-mx+b

What is the vertex of the graph of the function f(x) = x2 + 8x - 2?

vlabodo [156]

Answer:

Vertex is (-4, -18)

Step-by-step explanation:

f(x) = $ax^{2} +bx +c$

Let (h, k) be the vertex

An easy way to find h is to use the formula h = -b/2a

In your case where f(x) = $x^{2} +8x - 2$ a = 2 and b = 8

So, h = -8/2(1) = -8/2 = -4

Substitue -4 in for x to find k

k = ( $-4^{2}$ ) + 8(-4) - 2

= (16) - 32 - 2

= 16 - 32 - 2

= -18

Vertex is (-4, -18)

Note: Another way to find the vertex is to complete the square, but this can really be difficult in some cases

Will give BRAINLIEST Find the area of each circle . Round to the nearest tenth.

Oksi-84 [34.3K]

Answer:

13: 312yd squared

14: 907.5 rounded up but not rounded is 907.46

Step-by-step explanation:

this is because the formula is pi*r^2 so you'd

Step by step:

1. 20yd/2= 10 to get the radius for 13

2. substitute r in the formula pi*r^2 for 10 making it pi*10^2

3. multiply 10 by itself, 10*10=100

4. multiply pi by 100, 3.14*100= 314

314yd^2 is the answer for 13

14:

1. 34ft/2=17 to get the radius for 14

2. substitute r on the formula pi*r^2 for 17 making it pi*17^2

3. multiply 17 by itself, 17*17=289

4. multiply pi by 289, 3.14*289=907.46

5. round 907.46 to the nearest tenth, 907.5

907.5ft^2 is your answer

hope this helps :)

Can someone explain/show me how to do this?Absolute Value Functions

dedylja [7]

Domain: -∞<x<∞
Range: -∞<x<∞
X-Intercept: x=0
Y-Intercept: y=0
Increasing on the interval of 0<x<∞
Decreasing on the interval of -∞<x<0

When A=0, the graph equals y=0
- When A is greater than 1, it makes the graph skinnier than f(x)=|x|
- When A is less than 1 but greater than 0, it makes the graph fatter than f(x)=|x|
- When A turns negative, it flips the graph upside down.

-When B is greater than 0, it translates the graph to the right
- When B is less than 0, it translates the graph to the left

When C is greater than 0, the graph moves upwards
When C is less than 0, the graph moves downwards
