Answer:
1. tan
2. standard
3. y=16.8
Step-by-step explanation:
1. Trigonometic functions are:
sinA=opposite/hypoteneuse
cosA=adjacent/hypoteneuse
tanA=opposite/adjacent.
We have the opposite side (20) and the adjacent side (y), but not the hypoteneuse, ao we have to use tan.
2.Inverse is only used when we dont know the angle measure, so we use standard.
3.tanA=opp/adj
tan50=20/y
1.19175359259=20/y
y=16.7819926235 or 16.8

review the graph. given a pair of complex numbers, z1=5 and z2=-6i, let z3=3i+z1 and z4=z2-2. In which quadrant is z3-z4 located?
A. Quadrant 1
B. Quadrant 2
C. Quadrant 3
D. Quadrant 4
Answers
Answer:
A
Step-by-step explanation:
z₃ - z₄ is located in Quadrant 1, the correct option is A.
What are complex numbers?The numbers that can be expressed in the form of a + ib are called Complex numbers, i is called the iota, whose value is equal to the square root of -1.
These are imaginary numbers.
The complex numbers are
z₁ = 5
z₂ = -6i
z₃ = 3i +z₁
z₃ = 3i + 5
z₄ = z₂ - 2
z₄ = -6i -2
The mathematical operations in all the complex numbers are performed similarly in real numbers,
The like terms are grouped together.
The subtraction of the complex numbers has to be determined.
z₃ - z₄ = ( 3i + 5) - ( -6i -2)
z₃ - z₄ = 3i +6i +5 +2
z₃ - z₄ = 9i +7
The constant and the imaginary term depict the x and y coordinate respectively.
As both the terms are positive, it lies in Quadrant 1.

In the accompanying diagram ab is tangent to circle O at B and ACD is a secant.
If AB=9 and AD=27, find AC
Answers
Answer:
AC = 3
Step-by-step explanation:
Based on tangent and secant theorem, thus:
AB² = AC × (AC + CD)
AB = 9
AD = AC + CD = 27
Plug in the values
9² = AC × (27)
81 = AC × 27
Divide both sides by 27
81/27 = AC
3 = AC
AC = 3

If my radius is 10 what is my circumference
Answers
Answer:
Radius, r = 10 cm
Radius, r = 10 cmWe know, Circumference = 2πr=2×π×10=20π cm
The circumference of the circle is
20π cm or about 62.8 cm.
Here's how I did it:
The formula for a circumference of a circle is 2πr , where r is the radius. We can plug our known value of the radius ( 10 cm) into the formula and solve.
2π 10=20π cm or about 62.8 cm.
Step-by-step explanation:
The radius is half as long as the diameter, so the diameter can be thought of as 2r. Keeping this in mind, you can write down the formula for finding the circumference of a circle given the radius: C = 2πr. In this formula, "r" represents the radius of the circle.

A store is randomly giving away gift cards to the first 150 customers. They are giving 130 gift cards that have a value of $5 each and 15 gift cards that have a value of $50 each. The rest of the gift cards have a value of $100 each. Which is the probability that a customer will get a $100 gift card?
Answers
Answer:
1/30
Step-by-step explanation:
The total number of cards is 150. Subtract the numbers of the other values, 130 and 15 to get the number of $100 cards.
150 -145 = 5
5/150 is the number out of the total.
Simplify to get the probability: 1/30

What is the area of this figura?
Answers
Answer:
total area of the figure is: 1568 yd^2
Step-by-step explanation:
The area of the figure is the addition of the areas of a square and a rectangle:
The square on top that measures 28 yd times 28 yd, therefore its area is:
28^2 yd^2 = 784 yd^2
The rectangle at the bottom measures: 56 yd times 14 yd, therefore its area is:
Area rectangle = base x height = 56 yd x 14 yd = 784 yd^2
Then, the total area is the addition of these two:
Area of square + area of rectangle = 784 yd^2 + 784 yd^2 = 1568 yd^2
