I'll give you a hint. You had to used pemdas stands for: <u><em>p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtracting. </em></u>

First you had to calculate with parenthesis first.

$24/3+2$

Then you divide from left to right.

$8+2$

$=10$

Final answer: $\boxed{=10}$

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

PEMDAS so (9+15)= 24 , 24/3 = 8 , 8+2 = 10

Write an exponential equation in the form y = abx whose graph passes through points (4, 8) and (6, 32).

Artist 52 [7]

Answer:

Option C.

Step-by-step explanation:

The general exponential equation is

$y=ab^x$

It is given that the graph of exponential function passes through points (4,8) and (6,32). It means the equation of exponential function must be satisfied by these points.

$8=ab^4$ ...(1)

$32=ab^6$ ...(2)

Divide equation (2) by equation (1).

$\dfrac{32}{8}=\dfrac{ab^6}{ab^4}$

$4=b^2$

Taking square root on both sides.

$2=b$

Put b=2 in (1).

$8=a(2)^4$

$8=16a$

$\dfrac{8}{16}=a$

$0.5=a$

Substitute a=0.5 and b=2 in the given general exponential equation.

$y=0.5(2)^x$

Therefore, the correct option is C.

The function h(x)=1/x^2+1 is the result of the composition f(g(x)). If g(x) = x^2+1,what is f(x)? A f(x)=1/square root x B f(x)=

HACTEHA [7]

Answer:

Option B is correct

Step-by-step explanation:

Given: $h(x)=\frac{1}{x^2+1}$ is the result of the composition $f(g(x))$ .

Also, $g(x)=x^2+1$

To find: $f(x)$

Solution:

Take $f(x)=\frac{1}{x}$

Now check whether $h(x)$ is equal to $f(g(x))$ or not.

First find $f(g(x))$

$f(g(x))=f(x^2+1)=\frac{1}{x^2+1}$

Also, $h(x)=\frac{1}{x^2+1}$

Therefore,

$h(x)=f(g(x))$

So,

Option B is correct

√75+√3 can you show me the work to solve

vitfil [10]

Answer:

$6 \sqrt{3}$

Step-by-step explanation:

You need to factor out the greatest perfect square factor possible.

$\sqrt{75} + \sqrt{3} =$

$= \sqrt{25 \times 3} + \sqrt{3}$

$= \sqrt{25} \times \sqrt{3} + \sqrt{3}$

$= 5 \sqrt{3} + \sqrt{3}$

$= 6 \sqrt{3}$
