Answer:

Step-by-step explanation:

Set the polynomial equal to 0 first:

99x + 11 = 0. Now subtract 11 from both sides to get

99x = -11. Now divide both sides by 99 to get

x = -11/99 which simplifies down to

x = -1/9 so the first choice is the one you want.

To prepare for a bake-off, Chad used 520 grams of flour each day for 2 weeks. How many kilograms did Chad use in those 2 weeks?

Shalnov [3]

Answer:

7.280 k

Step-by-step explanation:

Given that 1 g = 0.001 k

If he uses 520 grams of flour each day for 2 weeks, since there are 7 days in a week, the total weight of flour used in two weeks

= 520 g * 2 * 7

= 7280 g

In kilograms

Since

1 g = 0.001 k

7280 g = 7280/1 * 0.001 k

= 7.280 k

A catapult launches a boulder with an upward velocity of 120 ft/s. The height of the boulder, h,

Vlad1618 [11]

Answer:

Reaches a maximum height of 235.00 feet in 3.75 seconds.

Step-by-step explanation:

The height of the boulder, h, in feet after t seconds is given by the function is given by :

$h=-16t^2+120t+10$ .....(1)

For maximum height, put $\dfrac{dh}{dt}=0$

i.e.

$\dfrac{d(-16t^2+120t+10)}{dt}=0\\\\-32t+120=0\\\\32t=120\\\\t=3.75\ s$

Put t = 3.75 in equation (1). So,

$h=-16(3.75)^2+120(3.75)+10\\\\h=235\ \text{feet}$

So, the boulder's maximum height is 235 feets and it takes 3.75 s to reach to its maximum height.
