Answer:

The answer is letter A.

(8x³ + 2x² - 7x + 2) ÷ (2x - 1)

8x³ + 2x² - 7x + 2 ÷ 2x - 1

(2x-1)(4x²+3x-2)÷2x-1

cancel 2x-1 so that the answer is 4x²+3x-2.

Which irrational number can be multiplied by - J41 to get a product that equals 1?
andreyandreev [35.5K]

Answer: -√1/✓41

Step-by-step explanation:

Let y be the irrational number that will be multiplied by -√41 to get the product that equals 1.

y × (-√41) = 1

We then solve for y, by dividing through with -√41. This will be:

[y × (-√41)]/-√41 = 1/-√41

y = -1/√41

y = -√1/✓41

The irrational number is negative root one over root forty one.

A soccer player uses her head to hit a ball up in the air from a height of 2 meters with an initial vertical velocity of 5 meter
Mandarinka [93]

Answer:1.32 s

Step-by-step explanation:

Given

The initial height of ball H=2 m

Initial velocity u=5 m/s

Height of ball at any instant is given by

H=-4.9t^2+5t+2

The ball will hit the ground when h=0

-4.9t^2+5t+2=0\\4.9t^2-5t-2=0\\t=\dfrac{5\pm\sqrt{25+4(4.9)(2)}}{2\times 4.9}\\t=\dfrac{5\pm\sqrt{64.2}}{9.8}\\t=\dfrac{5+8.01}{9.8}=1.32\ s\quad\text{Neglecting negative value of t}
