Leslie shows a funny video to 5 of her friends. Every hour, the video

Marat540 [252]

Answer:

10,935 views

Step-by-step explanation:

We can first design a formula for this scenario. Since the views triple this means that the initial views (i) needs to be multiplied by 3. Since this happens every hour we need to raise 3 to the power of the number of hours (h) that has passed by. This would give us the total number of views at that hour. Therefore, the formula would be the following...

i * $3^{h}$

We can input the values given to us into the formula and solve it for the total number of view. The initial number of views would be 5 (one for each friend) while we are trying to find the total number of views in the 7th hour.

5 * $3^{7}$

5 * 2187

10,935 views

Evaluate f(x) when x=-10

adell [148]

Answer:

f(x) = 10(10)+3 = 103 when x = 10

Step-by-step explanation:

Given a function piecewise as

f(x) = 2x-4 if -3<x<10

= x^2+3, if 10<=x<13

We see from the definition of f(x) that the function has domain as (-3,13) and two sets defined from (-3,10) and [10,13).

Since 10 less than or equal to sign is there in the second function interval, we find that 10 is included in that.

Hence for finding f(10) we use the function defined for interval including 10 i.e. x^2+3

Substitute 10 for x in x^2+3

f(10) = 10^2+3

=103

Hence answer is 103
