Answer:

see explanation

Step-by-step explanation:

Evaluate u for each value of n by substituting value of n into u, that is

n = - 1 → u = - 5(- 1)² + 4(- 1) = - 5(1) - 4 = - 5 - 4 = - 9

n = 0 → u = - 5(0)² + 4(0) = 0 + 0 = 0

n = 1 → u = - 5(1)² + 4(1) = - 5 + 4 = - 1

n = 2 → u = - 5(2)² + 4(2) = - 5(4) + 8 = - 20 + 8 = - 12

Thus

n u

- 1 - 9

0 0

1 - 1

2 - 12

∠3 and ∠4 are supplementary angles. If ∠3 measures 50°, what is the measure of ∠4

Sidana [21]

Answer:

130

Step-by-step explanation:

Supplementary angles are angles that are equal to 180 degree so if one is 50 degrees then the other must be added to it and get 180

180= 50 + ∠4

-50 -50

130=∠4

Compare the graphs below of the logarithmic functions. Write the equation to represent g(x).

Neporo4naja [7]

Answer:

The equation to represent g(x) will be $g(x)=log(x)+4$

Step-by-step explanation:

Considering the logarithmic function

$f(x)=log(x)$

As we know that when a constant c gets added to the parent function, the result would be a vertical shift c units in the direction of the sign of c.

So,

$g(x)=log(x)+4$ is basically the shift up by 4 units, and the graph also showing the same situation.

Therefore, the equation to represent g(x) will be $g(x)=log(x)+4$

Also, the graphs of both $f(x)=log(x)$ and $g(x)=log(x)+4$ is attached where black mark graph represents $f(x)=log(x)$ and red mark graph represents $g(x)=log(x)+4$ .
