Two skaters are racing towards the finish line of the race.the first Skater has a 40 meter lead and is traveling at a rate of 12 meter.the second skater is traveling at a rate of 14 meter per second.how long will it take for the second skater to pass the first skater?

Answers

Answer:

20 seconds

Step-by-step explanation:

The distance to cover between the lead skater and trailing skater is 40 meters

The lead skater's rate is 12 m/s

The trailing one's rate is 14 m/s

So, we can say:

second skater is accelerating, or covering up the distance, in 14 - 12 = 2 m/s

So, at a rate of 2 meters per second, how long would it take to cover 40 meters??

We use the distance formula, substitute the known and solve for unknown.

Distance Formula = D = RT

Where

D is distance

R is speed/rate

T is time

We know

r = 2 m/s

d = 40 m

t = ?

Now,

D = RT

40 = 2t

t = 40/2

t = 20 (seconds)

Hence,

it will take 20 seconds for the second skater to catch up (pass)

We're given a parabola

$y=x^2-4$

and a line

$y = 2x+b$

The zeros of the parabola are

$0=x^2-4$

$4=x^2$

$x=\pm 2$

We see that (-2,0) is on the line as well:

$y = 2x+b$

$0 = 2(-2)+b$

$b=4$

What does rounding to the nearest ten square feet mean?

Answers

Round to the nearest tens place.

Final answer:

Rounding to the nearest ten square feet means finding the closest multiple of ten to a given area in square feet.

Explanation:

Rounding to the nearest ten square feet means finding the closest multiple of ten to a given area in square feet. This is done by looking at the tens digit of the number. If the tens digit is 5 or greater, you round up to the next multiple of ten. If the tens digit is less than 5, you round down to the previous multiple of ten. For example, if you have an area of 67 square feet, rounding to the nearest ten square feet would give you 70 square feet.

Answer is B. 289

First find the area of the rectangle by multiplying Base x height. 17 x 13 = 221

Now to find the area of the huge triangle, you have to do (Base x height) / 2. So your height would be 8. Now your base would be the same as the length of the rectangle which is 17. (17 x 8) / 2 = 68

221 + 68 = 289

Answer is B. 289.....
