Answer:
b.
Step-by-step explanation:I think so
I believe its
40*2*1/2*pi meters per second
which is just
<h2><u><em>
40pi meters per second</em></u></h2>
if you need it simplified, its
<h2><u><em>
125.66370meters per second</em></u></h2>
Answer:
22 degrees.
Step-by-step explanation:
Please find the attachment.
We have been given that a man is in a tree-house 10 feet above the ground. He is looking at the top of another tree that is 22 feet tall.The bases of the trees are 30 feet apart.
To find the angle of elevation from the man's feet to the top of the tree, we will use tangent because we know adjacent side and opposite side to angle x.
Now, we will use arctan or inverse tan to solve for x as:
Upon rounding to nearest degree, we will get:
Therefore, the angle of elevation from the man's feet to the top of the tree is approximately 22 degrees.
Answer:
X+ 6
Y+ 1
Step-by-step explanation:
The image of point A after the reflection along the x-axis the is A(-5,-2).
When this point was translated the new point became A(1, -1). The is means the translation from (-5, -2) to (1, -1) can be given by:
for the x-coordinate
-5 + x = 1
x =6
for the y-coordinate;
-2 + y =-1
y = -1 + 2
= 1
Answers are
x + 6 and
y + 1
Answer:
59°, 71°
Step-by-step explanation:
This is a "sum and difference" problem. All problems of this type have the same answer: the larger of the two numbers is the average of those given.
Then the larger angle is (130 +12)°/2 = 71°. The smaller is 71° -12° = 59°.

<em>More detailed solution</em>
There are several ways to get there using equations. You can, for example, let L represent the larger number. Then L - D will be the smaller one (where D represent the difference). The sum of the two numbers (S) is ...
L + (L -D) = S
2L = S + D . . . . collect terms, add D
L = (S+D)/2 . . . the larger number is the average of the sum and difference
