Answer:
555.94
Step-by-step explanation:
16 x 11 = 176/2
88
since there are two of the same triangle
88 x 2
176
11 is the radius
A =
A = 3.14 ( pie is 3.14, if not then pi) x (11x11)
A = 3.14 x 121 (or 121)
A = 379.94
379.94 + 176 (or 121pi + 176)
555.94
Answer:
<h2>
7°</h2>
Step by step explanation
We know that the diagonals of a square bisects it's angles and every angles of square are 90°
m<BCD = 90°
m<BCA = m< DCA = 4x + 17
m<BCA + m<DCA = m <BCD
4x + 17 + 4x + 17 = 90
4x + 4x + 17 + 17 = 90
8x + 34 = 90
8x = 90 - 34
8x = 56
X = 56/8
x = 7
Hope this helps...

Step-by-step explanation:
Answer:
6 mph
Step-by-step explanation:
If x is the rate of boat (given x = 28)
and c is the rate of Gulf Stream (we need to find this)
The rate downstream is with the current, that is
x+c
THe rate of upstream is against the current, that is
x-c
We also know D = RT
D is distance
R is rate
T is time
It takes same time, so we can say:
t = D/R
So we can equate both to:
We can cross multiply this and solve for c:
The speed of current (rate of Gulf Stream) = 6 miles per hour
Answer:
Step-by-step explanation:
Given
Solving (a): (f o g)(x)
This is calculated as:
We have:
Substitute:
Evaluate the square
Using laws of natural logarithm:
So:
Hence:
Solving (b): The domain
We have:
The above function has does not have any undefined points and domain constraints.
<em>Hence, the domain is: </em>
