To find the scaled version of this rectangle by 1/2, start by identifying what this scale factor does to effect the numbers.

In this case, it causes each to divide by two.
Divide each value on the length and width of the rectangle by two.
This results in:
4/2
8/2

Now, perform the division to find your final answer.
This gives you 2 ft by 4 ft.

Answer choice C is the best option.

I hope this helps! :)

If you get $2,000 for graduation gifts and invest it in an account that earns 1.5% interest
Eduardwww [97]

Answer:

It is VERY important to use the attached formula.

Years = ln (Total / Principal) / rate

Years = ln (6,000 / 2,000) / rate

Years = ln (3) / rate

Years = 1.0986122887 / .015

Years = 73.24 years

This takes a LONG time because the interest rate is extremely low.

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)
