Answer:
m∠A = 144°, m∠B = 36°
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees.
Substitute 4(m∠B) for m∠A.
4(m∠B) + m∠B = 180
5(m∠B) = 180
<u>m∠B = 36°</u>
Substitute 36 for m∠B.
4(36) = m∠A
<u>m∠A = 144°</u>
The answer is a because they went 48 miles per hour, so when you put 48 in place of a, you will get 192 as your answer, thus prove it’s correct. Please mark me brainliest it would be pretty cash money of you
Answer:y = x 2 − 12 x The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. Interval Notation: ( − ∞ , ∞ ) Set-Builder Notation: { x | x ∈ R } The range is the set of all valid y values. Use the graph to find the range. Interval Notation: [ − 36 , ∞ ) Set-Builder Notation: { y | y ≥ − 36 } Determine the domain and range. Domain: ( − ∞ , ∞ ) , { x | x ∈ R } Range: [ − 36 , ∞ ) , { y | y ≥ − 36 }
Step-by-step explanation:
The formula for the area of a circle is pi times the radius squared. Here are the steps to solving this problem.
1. First, find the radius. Since the radius is allows half of the diameter, then we divide the diameter by two. 50/2= 25
2. Next, we square the radius. 25^2= 625
3. After that we multiply 625 ft by pi(3.14).
625 times 3.14= 1962.5
4. The last step is to round the the answer to the nearest square foot. Since 5 is at the end, we round up to 1,963.
So the answer is 1,963 ft^2.
