Answer:
Angle OAB = 90°
Reason: tangent theorem of a circle
Step-by-step explanation:
The diagram given shows a tangent line of the given circle with center O. The tangent touches the circle at point A.
The diagram also shows the radius of the circle, OA, drawn from the center to the circle to meet at the point of tangency.
Thus, according to the Tangent Theorem of a circle, the point at which the radius drawn from the center meets the point of tangency = 90°. The tangent is perdendicular to the radius drawn to meet at the point of tangency.
Therefore, angle OAB = 90°
we are given

we can use average rate of change formula from t=a to t=b

Here, we are given from t=1 to t=4
so, we will get formula as

now, we can plug values

now, we can simplify it

the average rate of change in the number of acres cleared for farming between t = 1 and t = 4 is 10 acres/ month.............Answer
Answer:
1376 minutes
Step-by-step explanation:
Alicia sews costumes for schools
She takes 86 minutes to sew one costume
Therefore the time taken to sew 16 costumes can be calculated as follows
86 mins= 1 costume
x= 16 costume
Cross multiply
x= 86×16
= 1376 minutes
Answer: last notation is right N =~ P
Step-by-step explanation: this is because any angle equals 180° but not less than 90° are regarded as supplementary angles. This means N<= 180°, P<= 180°
Answer:
The distance to his office is 2.5 miles.
Step-by-step explanation:
Given : Wade bicycles at a speed of 10 miles an hour and arrives at his office in only 15 minutes.
To find : What is the distance in miles to his office?
Solution :
The relationship between distance, speed and time is

The speed of bicycle is 10 miles per hour.
Time taken is 15 minutes.
Converting into hours,
1 hour = 60 minutes
1 minute =
hours
15 minute =
hours
15 minute = 0.25 hours
Substitute the value sin the formula,


Therefore, The distance to his office is 2.5 miles.
