Answer:
Step-by-step explanation:
The domain is the people and the range is the money spent
People would be counted as positive integers, only the last answer choice considers this.
<u>So the answer is:</u>
Distributive property is used when you have a number outside a set of numbers in parenthesis.
Using the distributive property, you multiply the number outside the parenthesis by each number inside the parenthesis.
The first answer is correct because they are multiplying 9 by 20 and adding it to 9 multiplied by 6.
Answer: tan A=4/3
Step-by-step explanation:
Theo đề ta có: 5sinA=4 suy ra: sinA=4/5, mà ta đã biết là: sinA= cạnh đối/cạnh huyền, suy ra: cạnh đối của góc A =4, cạnh huyền =5
Áp dụng định lí py ta go ta đc:
5^2=4^2+x^2
=) x=3
Vậy cạnh kề của góc A=3
Mà tanA = cạnh đối/cạnh kề
Vậy giá trị của tanA=4/3

Answer:
59
Step-by-step explanation:
The sum of the opposite interior angles of a triangle is equal to the exterior angle
4x+11 +51 = 10x -10
Combine like terms
4x+62 = 10x -10
Subtract 4x from each side
4x+62-4x = 10x-10-4x
62 = 6x-10
Add 10 to each side
62+10 = 6x-10+10
72 = 6x
Divide by 6
72/6 = 6x/6
12 =x
We want to find angle D
<D =4x+11
= 4*12 +11
= 48+11
= 59
