Answer:

Some ages that Mark could possibly be are...

16, 17, 18, 19, and 20. I found my answers because to have a job or work at a program, you have to be at <em>least</em> 16. So Mark could be 16, 17, 18, 19, or 20. He would be able to work being 21 because that is the drinking age and you are already in the adult stage and you are old enough to be responsible with what you do.  

Step-by-step explanation:

The ratio of the width to the length of a rectangle is 3:7. The shorter side is 9 inches long. What is the longer side and also
photoshop1234 [79]

shorter side : longer side = 3 : 7


Equate 3 parts tp 9 inches:

3 parts = 9 inches


Find 1 part:

1 part = 9 ÷ 3 = 3 inches


Find 7 parts:

7 parts = 3 x 7 = 21 inches


Area = Length x Width = 21 x 9 = 189 in²


Answer: The longer side is 21in and the area is 189 in²

The hypotenuse of a 45-45-90 triangle has a length of 10 units. what is the length of one of its legs?
Blizzard [7]

the length of a leg on a 45-45-90 triangle given the hypotenuse is half the length of the hypotenuse times sqrt(2)

hypotenuse = 10

 10/2 =5

 so the answer should be 5sqrt(2), which I don't see as a choice

Solve the following function for y when x=5 round to the nearest tenth
Wittaler [7]

In the given question , we have a function given , which is

y= 13(0.5^x)

And we need to find the value of y when x=5.

So we substitute 5 for x and solve for y, that is

y=13(0.5^5) = 0.40625

And on rounding to the nearest tenths, we will get

y=0.4

So when x=5, y=0.4

What kind of question will ask us to use this type of format to evaluate the integral instead of doing the regular integral eval
ANEK [815]

Answer:

Great work!

Step-by-step explanation:

These kind of questions are calculated through Riemann Sum. You can evaluate any definite integral using the Riemann Sum. It should be in the following form:

f(x)dx on the interval [a, b], or

\int _a^b\:f\left(x\right)dx

Now f(x) is simply y. Therefore in this example y = x^3 - 6x. We just need the sufficient amount of data to apply the Riemann Sum, including the interval [a, b] that bounds the area, and the the number of rectangles 'n' that we need to use.

Consider an easier approach to this question: (First attachment)
