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

layers more easily hit their intended targets.
The code works such that if the player is aimed at
A
AA but instead should be aimed at target
T
TT, the game will automatically adjust the angle at which the arrow is fired directly at
T
TT.
If
A
AA and
T
TT are
15
1515 meters apart in the example below, how many degrees will Maricel's code adjust the shot?
Do not round during your calculations. Round your final answer to the nearest degree.

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

The product of two rational number is 7. If one of the number
FinnZ [79.3K]

Answer:

7/12 OR 0.58 (2.d.p)

Step-by-step explanation:

Product means that the two rational numbers are being multiplied to get 7.

The question also tells us that one of them is 12. Therefore we can write an equation to express this information where we represent the unknown rational number using the letter 'r':

r x 12 = 7

Rearrange to find r:

r x 12 / 12 = 7 /12

r = 7/12 = 0.5833....

= 0.58 (2.d.p)

Hope this helped!

Evaluate the expression 3(7 + 4)2 − 14 ÷ 7. 50 361 363 586
Kipish [7]
It appears that none of your option choices are correct,, are you sure you copied them right ? I will show you how to solve this and how I got my answer.
The first step for solving this is to add the numbers in the parenthesis.
3 × 11 × 2 - 14 ÷ 7
Divide -14 by 7.
3 × 11 × 2 - 2
Divide the first 3 numbers together.
66 - 2
Subtract the numbers together to get your final answer.
64
Let me know if you have any further questions.

What is the answer to the Brain Teaser below
lawyer [7]

Answer:

19

Step-by-step explanation:

The boots are the value of 10, since 3 equal 30. The man is the value of 5 since there are two men (10) and one boot (also 10) which made 20. The ribbon is the value of 4 since there is one man (5) and 2 ribbons (8 ) which made 13. add 10, 5 and 4 and you get 19.
