A toy falls from a window 70 feet above the ground. How long does it take the toy to hit the​ ground?
Korolek [52]

Answer:

2.09 seconds.

Step-by-step explanation:

We are given...

y = 70 feet

v0 = 0 feet/second

a = 32 feet/second^2

We need to find t using the following equation...

y = v0 * t + (1/2) * a * t^2

70 = 0 * t + (1/2) * 32 * t^2

70 = (1/2) * 32 * t^2

70 = 16t^2

16t^2 = 70

t^2 = 4.375

t = sqrt(4.375)

t = 2.091650066

So, it will take the toy about 2.09 seconds to hit the ground.

Hope this helps!

Find the point on the graph of 2x+3y=12 where x=3
mafiozo [28]

Answer:

(3,2)

Step-by-step explanation:

2x+3y=12

substitute x with 3 because x=3

2(3)+3y=12

multiply

6+3y=12

(subtract 6 from both sides)

3y=6

(divide by 3 on both sides)

1y=2

x = 3 and y = 2

I need help..............
vovangra [49]

Answer:

  a_n=-3+7(n-1)

Step-by-step explanation:

The recursive rule tells you the initial term of the sequence is a1 = -3, and the common difference is d=7. (7 is the value added to one term to get the next term.)

Putting these values into the formula for the explicit rule gives ...

  an = a1 +d(n -1)

  an = -3 + 7(n -1)

In a recent survey of favorite sodas 7 students chose coke. If these students represent 17.5% of the students surveyed, how many
katovenus [111]

Answer:

40

Step-by-step explanation:

7 = 17.5% × Y

STEP 2 7 =

17.5

100

× Y

Multiplying both sides by 100 and dividing both sides of the equation by 17.5 we will arrive at:

STEP 3 Y = 7 ×

100

17.5

STEP 4 Y = 7 × 100 ÷ 17.5

STEP 5 Y = 40
