What’s the answer thank you

Mathematics
1 answer:
Usimov [2.4K]3 years ago
5 0

Answer:

C

Step-by-step explanation:

Division can be done by "cross multiplying", or multiplying the first equation by the reciprocal of the second equation.

In answer c, the first term remains the same, but the second is the reciprocal of the original.  Also, the operator has changed from division to multiplication, so C is the correct answer.

2x^3-3x^2+kx-1 is divided (x-1),the remainder is 2 find k
Debora [2.8K]

Answer:

k = 4

Step-by-step explanation:

if f(x) is divided by (x - h) then f(h) is the remainder

f(x) = 2x³ - 3x² + kx - 1

divided by (x - 1) , so h = 1 , then

2(1)³ - 3(1)² + k(1) - 1 = 2

2 - 3 + k - 1 = 2

- 2 + k = 2 ( add 2 to both sides )

k = 4

A tank currently holds 5 gallons of water. It is being filled at the rate of 1/4 gallon per minute. How long will it take for th
Verdich [7]
So we know the tank already has 5 gallons and we need 9. This means we need 4 more gallons in order to fill up the tank.

If 1/4 gallon is being filled per minute we need to find out how many 1/4 gallons makes up 4 gallons in total.

4 of the 1/4 gallons makes up 1 whole gallon. So since we need 4 whole gallons we would need 16 of the 1/4 gallons.

This means that it will take 16 minutes for the tank to hold 9 gallons of water.
