a is a leg b is another leg c is the hypotenuseStep-by-step explanation:
Step 1: Define
Leg a = 9
Leg b = 7
Hypotenuse c = x
Step 2: Solve for x
Substitute in variables [Pythagorean Theorem]: 9² + 7² = x²[Hypotenuse] Rearrange: x² = 9² + 7²[Hypotenuse] Evaluate exponents: x² = 81 + 49[Hypotenuse] Add: x² = 130[Hypotenuse] [Equality Property] Square root both sides: x = √130Related Questions

Answer: It is one-half the area of a rectangle with sides 2 units × 3 units.
It is twice the area of a square of side length 3 units.
It is one-half the area of a square of side length 3 units.
Step-by-step explanation:
Answer:
It is one-half the area of a rectangle with sides 2 units × 3 units.
Step-by-step explanation:
because the base of the triangle is connected in the "quadrilateral way" the base is one-half the rectangle and the units are 2x3 so therefore that answer is the correct one.

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.

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

Answer:The fourth function
Step-by-step explanation:
You can never have repeating x-values. You can have repeating y-values though. Whenever determining whether something is a function, just look at whether it has repeating x-values or not. If it does, it is not a function. If it doesn't, it is a function.
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.
