Answer:
Step-by-step explanation:
- Diameter = 42 inch
- Speed = 25 rpm
<u>Circumference of the tire:</u>
- C = πd = 3.14*42 = 131.88 inches
<u>Distance per minute</u>
- 25 revs = 25C =
- 25*131.88 =
- 3297 inches = 274.75 feet =
- 274.8 feet rounded
The measurement of the given angle is 30 degree.
Here we use trigonometric ratio rule which is sin theta= opposite/hypotenuse
Here theta = 30 degree, opposite =7 and hypotenuse =a
So we get
sin 30 = 7/a
a= 7/sin 30
And value of sin 30 = 0.5
So we get , a = 7/0.5 = 14
So the value of a is 14 .
the center is : (-8 , 12)
Answer:
-3.5
Step-by-step explanation:
Whenever the x is 0, the graph hits the y axis
Answer:
The correct answer is 1/49
Step-by-step explanation:
In order to find this, we first can eliminate the negative in the exponent by putting the whole this in the denominator.
(-7)^-2 = 1/(-7)^2
Now we can evaluate the denominator
1/(-7)^2 = 1/49
