1 answer:

7 0

(f ° g) (x) means the composition of the two functions in this order f (g (x) )

So, given f(x) = - 9x + 9 and g(x) = √(x + 1), you must do this:

f(g(x)) = - 9 [ g(x) ] + 9 = - 9 [√(x+1) ] + 9 => f(g(24) = - 9 √(24 + 1) + 9 = - 9√25 + 9 =

= -9(5) + 9 = -45 + 9 = - 36

Answer: - 36

What is 1/7 divided by 252 ?

miskamm [114]

Answer:

In decimal form: $0.00056689342$ (If wanted to round to nearest thousandth, $0.001$ )

In fraction form: $\frac{1}{1764}$ or $\frac{28344671}{50000000000}$

Step-by-step explanation:

$\frac{1}{7}\div \:252=\frac{1}{1764}$

$\mathrm{Convert\:element\:to\:fraction}:\quad \:252=\frac{252}{1}\\=\frac{1}{7}\div \frac{252}{1}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}\\=\frac{1}{7}\times \frac{1}{252}$

$\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}\\=\frac{1\times \:1}{7\times \:252}$

$\mathrm{Multiply\:the\:numbers:}\:1\times \:1=1\\=\frac{1}{7\times \:252}$

$\mathrm{Multiply\:the\:numbers:}\:7\times \:252=1764\\=\frac{1}{1764}$

Hopes this helps you!

Have a wonderful night!

I need help with this question

zhuklara [117]

Answer: 5x - 1 = -6

Step-by-Step Explanation:

We have this diagram here showing numbers and symbols. Just a remainder, "X" is a variable which can be found through and equation of Algebra. Alright, so we have 5 boxes with the symbol "X". Alright, that's a start, so we have 5x as a start of the equation. We have -1 on the same side as well.

Alright, so on the other side- we have Six symbols of "-1".

That concludes to... -6. Alright, notice how all of the symbols are on a Scale, so we can heavily imply that the "=" symbol will take place between the two sets of symbols. Alright, combining them we get.. 5x - 1 = -6.

If you need further instructions/help, don't hesitate to give me a shout out. Bye, and I hope this helps.
