answer for blank 1:

2 seconds

Step-by-step explanation:

Given : Heather hits a tennis ball upward with an initial speed of 32 feet per second.

To Find: After how many seconds does the ball hit the ground

Solution:

Formula :

Where h is the height

r is the initial speed

So, initial speed = r = 32 feet per second

Now we are supposed to find After how many seconds does the ball hit the ground i.e. h =0

Substitute h=0 in the formula

Thus after 2 seconds the ball will hit the ground.

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
