Answer:

10 seconds

Step-by-step explanation:

we are given the height (s) which is 1600ft. and the formula—where t is time in seconds— t= 1/4 $\sqrt{s}$ , so we can plug 1600ft in for s and solve:

t= 1/4 $\sqrt{1600}$

t= 1/4(40)

t= 10 seconds

Please completely factor the following expression. e. 3x^2+5xy-2y^2

kramer

3x^2 + 5xy - 2y^2

Simplifying:

3x^2 + 5xy + - 2y^2

Reorder Terms:
5xy +3x^2 + - 2y^2

Factor a Trinomial.
(3x + - 1y)(x + 2y)

Final Result:
(3x + - 1y)(x + 2y)

Hope this helps!!!

What is the product of 9 radical 5 and 5 radical 10 in simplest radical form?

tatuchka [14]

Answer:

Step-by-step explanation:

(9√5) (5√10)

The leading interger product is found by multiplying 9 and 5

The leading integer product is 9*5 = 45

The radical product is (√5*10

Factor 10

radical product = √5*2*5

There are 2 fives underneath the radical. Take one out and ignore the other

radical product = 5√2

The 5 now multiplies by 45 and √2 becomes part of the answer

5*45√2

225√2
