For this case we must find the product of the following expression:

2y ^ 2 (3x + 5z)

We apply distributive property to the terms within parentheses:

6y ^ 2x + 10y ^ 2z

Finally, the answer is:

6y ^ 2x + 10y ^ 2z

Answer:

2y ^ 2 (3x + 5z) = 6y ^ 2x + 10y ^ 2z

A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t^2+64t+80 gives the height, in feet, of the ball
Wewaii [24]

Answer:

<h3>5 seccs</h3>

Step-by-step explanation:

Given the modeled function of the height expressed as;

h(t)=-16t^2+64t+80

The ball hits the ground when h(t) = 0 (when the height is zero)

Substitute into the function and find t;

0 =-16t^2+64t+80

divide through by -16

0 = t²-4t-5

Factorize;

t²-4t-5 = 0

t²-5t+t-5 = 0

t(t-5)+1(t-5) = 0

(t+1)(t-5) = 0

t + 1 = 0 and t-5 = 0

t = -1 and t = 5

Time can't be negative

Hence it will take the ball 5secs before it hits the ground

Vika [28.1K]
260 quarts * 36 hours = 9,360 quarts
260 * 20 hours = 5,200 quarts ---> 260 quarts / 10 hours = 26 quarts per hour ---> 26 quarts * 4= 104 quarts ---> 5,200 + 104 = 5,304 quarts per day

How many different groups of three kids can you make from seven kids?
katovenus [111]
This is combination problem since the order or arrangement matters. This is easily solvable with your scientific calculator. The formula would be nCr, where n is the total number of persons, and r is the number of persons in a group. So, using your calculator,

7C3 = 35

There can be 35 different groups.
