Step-by-step explanation: In this problem, we're asked to state the domain and range for the following relation.
First of all, a relation is just a set of ordered pairs like you see in this problem. The domain is the set of all x-coordinates for those ordered pairs. So in this case the domain or D is {2, 5, -1, 0, -3}.
The range is the set of all y-coordinates for those ordered pairs. So in this case our range or R is {4, 3, -4, 9, 1}.
<span>Semicircle area = circle area / 2 = (pi*r^2)/2
16 in is the radius. Let's call the area of this semicircle s.
3.14*16^2=s
</span><span>Trapezoid area = ((base 1 + base 2) / 2) * h
Here, base 1 is 44 and base 2 is 36. The height (h) is 20. Let's call this trapezoid's area t.
(44+36)/2 *20 = t
</span>
<span>We can remove the area of the semicircle (that created by the windshield wiper) by subtracting it from the area of the trapezoid.
t - s = uncleaned area
[(44+36)/2 * 20] - [3.14 * 16^2] = uncleaned area</span>
Answer:
X=60
Step-by-step explanation:
Sum of the Quadrilateral interior angles:360
360-70-130-100=60
The number is 12.
7 + 5 = 12
12 • 3 = 36
Hope I helped!
Answer:
Step-by-step explanation:
94
Mean = add all the numbers up and divide by how many numbers you added
So add (x +120 + 112 + 130 + 128 + 124 ) divided by 6 =118
x is the score you are looking for and 118 is the average he wants
so (x + 614 ) divided by 6 =118
now multiply both sides by 6
x + 614 = 118 times 6
x + 614 = 708
subtract 614 from both sides
x = 94
