Vertex 0,-1 and axis of symmetry is x=0

Answer: See explanation

Step-by-step explanation:

Vertex is the point where two lines meet.

The vertex of the function is (0, -1)

The axis of symmetry is a line that divides the function into two symmetrical lines.

The axis of symmetry is x = 0 since that's the line that meets with the vertex and it makes the lines symmetrical.

Explain how precipitation happens. Use complete sentences and give at least two supporting details​

Answers

Answer:

Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. ... Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth.

Step-by-step explanation:

the sun evaporates the water from a stream or some type of water source and it then gets collected  into the clouds and then condensation and the last step is when the water is too heavy so the clouds release it and that is called precipitation. hope this helps.

Annie went bowling. It cost $3 to rent shoes, plus $4 for every game that she played. She spent $11 total. How would you represent this situation using an equation, and using algebra tiles?

Answers

Answer:

Step-by-step explanation:

3+4g=11, subtract 3 from both sides

4g=8, divide both sides by 4

g=2, so two games were played

3s + 4g= $11

S= means shoes
G= means games

The question is: There are 28 girls and 22 boys on a swim team what percent of the team is made up of boys? explain why pls.

Answers

Answer:

U first need to find out the total number of people

22+28

50

and since they are asking only for boys we need to put the number of boys on the numerator and the total number of people at the denominator

22/50

And now to make it into % we need to ALWAYS multiply the fraction by 100

22/50 x 100

44%

Hope it helps

Answer:

44 %

Step-by-step explanation:

okay so 100% is equal to the whole team or 50 swimmers

100% = 50 swimmers

to find out how much one swimmer is would be to divide the 100% by the total of swimmers.

100% / 50 swimmers

2% = 1 swimmer

so now that we know how much percent 1 swimmer is we will multiply 2% by 22, the number of boy swimmers.

2 x 22 = 44

Answers

Answer:

a. 14

b. 1

c. 2

Step-by-step explanation:

If there are 4 one point questions and 5 two point questions, then 5 multiplied by two is 10 and adding it to 4 is 14. The quiz would be 14 points total. If you scored 87.5% on the quiz then you would know that you got 12 of the questions correct and you would know that by finding 87.5% of 14 which the equation to do so would be 87.5/100= 0.875, then 0.875* 14= 12.25. If you round 12.25 to the nearest whole number then it's 12. And since you got all the 1 point questions right, then you must of gotten 1 two point question wrong.

I hope this helps!

The measure of angle AFB = 78°

Answers

Answer: is C

Step-by-step explanation: you have a 90 so 90-78 is 12

The answer is 12

We know that angles AFB and CFD and BFC sum up to 180

Using this information we can write the equation

AFB + CFD +BFC = 180

Now substitute known values:

78 + 90 (it is a right angle) + BFC = 180

Now solve-
You should get

180-168 which is 12
