Mathematics
1 answer:
Bingel [31]3 years ago
3 0

Answer:

C. 5,400

Step-by-step explanation:

To find the volume of a rectangular prism, it is length * width * height

The first rectangular prism

15 * 20 = 300

300 * 9 = 2700

The two rectangular prisms are the same so just multiply it by 2

2700 * 2 = 5400

C. 5400 is your answer

Select 2 of the following
siniylev [52]

Answer:

OPTION C: The ratio is a constant.

OPTION E: The ratio is equal to b.

Step-by-step explanation:

Given: $ f(x) = a.b^x $

The ratio of f(x + 1) and f(x) = $ \frac{f(x + 1)}{f(x)} = \frac{a.b^{x + 1}}{a.b^x} $

Since, $ a^{x + 1} = a^x. a $

$ \implies \frac{f(x + 1)}{f(x)} = \frac{a.b^x.b}{a.b^x} $

Cancelling out $ a.b^x $ we get:

$ \frac{f(x + 1)}{f(x)} = b $

This shows that the ratio is always a constant and that constant is equal to b.

What is the value of y when -5 =<br> = y - 7?<br> 9<br> a. -7<br> b.-11<br> C. -38<br> d. -52
weqwewe [10]

Answer:

2

Step-by-step explanation:

You have to cancel the -7 so you would add +7 to each side.

-7+7=0, -5+7= 2

y=2

Although this isn't an answer choice. Did you mistype something?

What is the simplified form of StartRoot StartFraction 72 x Superscript 16 Baseline Over 50 x Superscript 36 Baseline EndFractio
aalyn [17]

Answer:

  StartFraction 6 Over 5 x Superscript 10 Baseline EndFraction

Step-by-step explanation:

Apparently you want to simplify ...

  \sqrt{\dfrac{72x^{16}}{50x^{36}}}

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  1/a^b = a^-b

  (a^b)^c = a^(bc)

__

So the expression simplifies as ...

  \sqrt{\dfrac{72x^{16}}{50x^{36}}}=\sqrt{\dfrac{36}{25x^{36-16}}}=\sqrt{\dfrac{36}{25x^{20}}}\\\\\sqrt{\left(\dfrac{6}{5x^{10}}\right)^2}=\boxed{\dfrac{6}{5x^{10}}}
