Writing and solving an equation of ratios would seem to be the best way to go.

0.045 sec       3 sec
------------- = ------------
1 image           x

Then 0.045x = 3, and x = 66 2/3 images, best rounded down to  66 images.

What is the average rate of change of F over the interval [0,7]?
ryzh [129]

Answer:

0

Step-by-step explanation:

Note that we start at (0, -4) and end at (7, -4).  Thus, the net change in y over the interval [0, 7] is 0, and the average rate of change of f(x) over that interval is thus

5x−2.5+6x−3= ___ (2x−1)
LiRa [457]

Answer:

5.5

Step-by-step explanation:

So, this is a simple factoring problem. The answer is 5.5(2x-1). So, heres how we get that answer.

So, factoring is basically breaking down the problem into smaller parts. So once we simplify the problem, we can factor it.

Simplify by combining like terms: 5x+6x= 11x and -2.5-3=-5.5

Now we have 11-5.5=?

so, we need to have (2x-1) in our answer because the problem asks for that in the answer.

We need to find a number that satisfies the equation and answer

so, 5.5(2x) is 11x, and 5.5(-1) is 5.5.

5.5 satisfies the equation, therefore is the answer

lakkis [162]

Answer:

GH = 7\sqrt{2}

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = \frac{1}{\sqrt{2} }

sin45° = \frac{opposite}{hypotenuse} = \frac{HI}{GH} = \frac{7}{GH} = \frac{1}{\sqrt{2} } ( cross- multiply )

GH = 7\sqrt{2}
