Answer:

C

Step-by-step explanation:

Hello There!

so

y = -5x^2 + 8x +4

where y = height of ball and x = seconds after ball was thrown

The plus 4 is the y intercept and because y equals height of ball the 4 would represent the height that the ball was thrown at

Do this plz. Don't understand this.
Alexus [3.1K]
I might not be right here but i think its C, now before you just leave to circle the answer, find out why: Multiply 54 and 8 to find out how many TOTAL square tiles you need. The answer would be 432. Then since it says 8 groups of 4 blue tiles, this mean 8*4, which is 32. 32 of the TOTAL square tiles would be blue. subtract 432-32 to get 400 because the question is asking for the WHITE tiles. this is why you subtract the total tiles from the blue tiles to get the white tiles.

We have a right triangle that has am 8 meter and 21 meter leg .Find the hypotenuse
Serjik [45]

Answer:

hypotenuse is 22.47 m

Step-by-step explanation:

The length of both legs of a right angle triangle are 8m and 21 m

We need to find the hypotenuse

To find hypotenuse we use Pythagorean theorem

Hypotenuse is AC  and other two legs are AB  and BC

AC^2 = AB^2 + BC^2

Hypotenuse ^2 = 8^2 + 21^2

hypotenuse = \sqrt{8^2 + 21^2}

= \sqrt{64 + 441}

= \sqrt{505}

= 22.47

So the length of the hypotenuse is 22.47 m

AlexFokin [52]

Based on the fact that Tim forgot to refuel the vehicle and the amount per gallon at the rental place, Tim will have to pay an extra amount of d. <u>$57.88.</u>

<h3>How much will Tim pay?</h3>

According to the conditions, Tim will have to pay for the complete refueling of the car should he forget to refuel. He will also have to pay a $5.00 refueling fee.

The car is almost empty which means he will also pay for the entire capacity of the car.

The amount Tim will pay is:

= (Cost per gallon x Total fuel capacity) + Refueling fee

= (4.50 x 11.75) + 5

= $57.88

In conclusion, option D is correct.
