Answer:

f(g(t)) = 2t² + 1

Step-by-step explanation:

You can solve this simply by substituting g(t) into f(t), and solving for f(g(t)):

[tex]f(t) = 2t + 5\\\\g(t) = t^2 - 2\\\\f(g(t)) = 2(g(t)) + 5\\\\f(g(t)) = 2(t^2 - 2) + 5\\\\f(g(t)) = 2t^2 - 4 + 5\\\\f(g(t)) = 2t^2 + 1[/tex]

and m<7=
PLEASE HELP BRAINLIEST ​

Answers

Answer:

m<5 = m<7 = 127

Step-by-step explanation:

m<2 = m< 8 because they are alternate interior angles.

So angle 8 is 53 degrees.

m<8 + m<7 = 180 because they form a straight angle.

Since angle 8 is 53 degrees as previously established, angle 7 has to be 127 degrees.

And since angles 7 and 5 are opposite angles, they have the same value, so both angles are 127 degrees.

Use the second derivative test to find the relative extrema for f(x)=x^4-2x^2 + 3​

Answers

If f(x) = x ⁴ - 2x ² + 3, compute the first and second derivatives:

f'(x) = 4x ³ - 4x

f''(x) = 12x ² - 4

Solve f'(x) = 0 to get the critical points of f(x) :

4x ³ - 4x = 4x (x ² - 1) = 0

→   x = -1, x = 0, x = 1

Check the sign of the second derivative at each of these points:

f'' (-1) = 8 > 0

f'' (0) = -4 < 0

f'' (1) = 8 > 0

These indicate the presence of

• two minima of f (-1) = 2 and f (1) = 2

• one maximum of f (0) = 3

which makes C the correct answer.

Explain how to get the variable alone in the equation. 3x = 24​

Answers

Answer:

to get rid of the 3 on the x you have to divide it by 3. whatever you do to one side you have to do to the other side so the answer would be x=8

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

To get the variable alone you would divide both sides by 3. You do this because 3 is a common factor that both 3 and 24 have. Once you divide 3 on each side, you have x = 8 as your final answer.

I do not know what to put and this was due yesterday

Answers

Answer:

Your answer will be x=2

Step-by-step explanation:

Five plus 6 times a number is equal to 21 minus 2 times the number

Your equation is this:

5+6x=21-2x

Subtract 6x from both sides

5+6x-6x=21-2x-6x

5=21-8x

subtract 21 on both sides

5-21=21-21-8x

-16=-8x    Divide -8 on both sides

2=x
