Complementary angles are adjacent angles which add to equal 90 degrees (a right angle). To find m∠A in these figures, set the sum of the known angle measure and the unknown angle measure, A, equal to 90 and solve.

10)
90 = 67 + A
23 = A
m∠A = 23°

11)
90 = 57 + A
33 = A
m∠A = 33°

12)
90 = 44 + A
46 = A
m∠A = 46°

Just subtract what they give you from 90.
For example, #10 would be 90-67=A

Consider the functions f(x) = -2(x-3)² + 2 which is represented by the graph
ehidna [41]

The intervals of the function on the graph are:

  • Domain = (-∝, ∝)
  • Range = (-∝, 2]
  • Increases (-∝, 3]
  • Decreases [3, ∝)

<h3>The key features of the function?</h3>

The function is given as:

f(x) = -2(x-3)² + 2

See attachment for the graph.

From the graph, we have;

Domain = (-∝, ∝)

Because it takes all real values as its input

Range = (-∝, 2]

Because it has a vertex of (3, 2) and the vertex is a maximum

Also, it increases on the interval (-∝, 3] and decreases on the interval [3, ∝)

Point A is at (-1,-9) and Point M is at (0.5,-2.5).
leva [86]
  • Midpoint Formula: (\frac{x_2+x_1}{2},\frac{y_2+y_1}{2})

So firstly, let's start with the x-coordinates. Since we know the midpoint's x-coordinate and point A's x-coordinate, we can solve for point B's x-coordinate as such:

\frac{-1+x}{2}=0.5\\\\-1+x=1\\\\x=2

Next, do the same thing except solve for the y-coordinate and using point A's y-coordinate and the midpoint's y-coordinate:

\frac{-9+y}{2}=-2.5\\\\-9+y=-5\\\\y=4

<u>Putting it together, point B's coordinates are (2,4).</u>

When you forget to add the attachment,, r.i.p. ,, what I said before and all that
kati45 [8]
a.
h = 2c - 3

b.
3h + 1.5c = 201

c.
We have a system of equations from part a and b.
h = 2c - 3   (equation 1)
3h + 1.5c = 201   (equation 2)

We use substitution method to solve this system.
Substitute equation 1 in equation 2 to get
3h + 1.5c = 201
>> 3(2c - 3) + 1.5c = 201
>> 6c - 9 + 1.5c = 201
>> 7.5c = 201 + 9
>> 7.5c = 210
>> c = 210 / 7.5
>> c = 28

Plug this value back in equation 1 to get
h = 2c - 3  
>> h = 2(28) - 3 = 56 - 3 = 53

So, c = 28 and h = 53 implies that <u>28 corndogs</u> and 53 hotdogs were sold.

An employee earns a 12% commission rate on the cameras he sells. If he earns $384 in commission, what were his total sales?
Vlad1618 [11]
I do questions like these a little different than most people so...

384/12= 32 (32 is 1% of his sales)
32*100= 3200

His total sales were $3200.
