Answer:
Step-by-step explanation:
I think the question is card(A)=20,card(B)=15,card(A∩B)=10, then what iscard(A∪B)
You can solve this question by drawing a picture like this to visualize the problem.
Thus the answer is card(A∪B)=card(A)+card(B)−card(A∩B)=25
-3.618 / 1.8 = -2.01
you can use long division or a calculator to do this, but calculator is a lot easier.
In a right triangle, this formula can be used:
a^2 + b^2 = c^2
when a and b are the legs and c is the hypotenuse.
Substitute the numbers from the problem into the formula.
14^2 + b^2 = 18^2
Simplify.
196 + b^2 = 324
b^2 = 128
b = square root of 128 = 11.3137...
When 11.313 is rounded to the nearest tenth, it is 11.3
The length of the other leg is 11.3 centimeters.

The degree of a polynomial is the greatest exponent. In this case, the degree is 8.
The polynomial is a trinomial because it has 3 terms.
Answer:
y= 5x+10
Step-by-step explanation:
Inverse basically means y is now x and x is now y.
y= x/5 -2 becomes x= y/5 -2
Remember to always leave your equation f(x) = ...
i.e. y =...
x= y/5 -2
add 2 both sides
x+2 = y/5
multiply 5 both sides
5(x+2) = y
Hence,
y= 5x + 10
Hope this helps!
