Hey there! :)

Answer:

B.

Step-by-step explanation:

To find the solution to the inequality, we can begin by solving for 'x':

2x + 1 ≥ 3

Subtract 1 from both sides:

2x ≥ 2

Divide both sides by 2:

x ≥ 1.

This means that the graph must contain all values of x greater or equal to one. The only number line that shows solutions greater than 1 is B.

Let f ( x ) = 2 x − 1 , g ( x ) = 3 x , and h ( x ) = x ^2 + 1 , what is h( h ( 5) ) ?
strojnjashka [21]
First you would solve for h(5) by plugging in 5 as your x, then solving it.

h(5) = 5^2 + 1
h(5) = 25 + 1
h(5) = 26

Next you would multiply the 26 by the individual h, which is basically h(1).

h(1) = 1^2 + 1
h(1) = 2

Lastly you multiply your h(1) value by the h(5) value to get your answer.

h(1) • h(5) = 26 • 2
h[h(5)] = 52

Maricel is programming an archery component of a new video game. In her code, she has created an "auto aim" feature that helps p
trasher [3.6K]

Answer:

  • <u>12º</u>

<u></u>

Explanation:

The angle Marcel's code adjust the shot can be calculated using the cosine law:

        C^2=A^2+B^2-2|A||B|cos(c)

For the triangle of the figure:

  • C = 15m
  • A = 50m
  • B = 60m
  • c = ? (the unknown angle)

Substitute and solve for c:

      (15m)^2=(50m)^2+(60m)^2-2(50m)(60m)cos(c)\\\\\\225=2500+3600-6000cos(c)\\\\6000cos(c)=2500+3600-225=5,875\\\\cos(c)=5,875/6000\approx0.97917\\\\c=arccos(0.97917)\approx12\º
