Answer:
∠C=90°
∠A=67°
∠B=23°
Step-by-step explanation:
For angle C:
Thales' Theorem states that an angle inscribed across a circle's diameter is always a right angle.
Therefore, since AB is the diameter(hypotenuse) then angle C is the right angle. (90°)
For Angle A:
The measure of arc BC= 134 degrees. We can just use a formula for an inscribed triangle. ∠A = 1/2 (mBC)
∠A= (1/2)134
∠A= 77°
For angle B:
All triangle angles all add up to 180. We can just subtract angles A and C from 180°:
∠B = 180-(90+67)
∠B = 23°
The answer would be -26
-(-4)^2-10
-4 squared is 16 times -1 is -16
-16-10
-26
200.
Twenty groups of ten = 20x10
20x10 = 200
Question 21
Selling price = 18 + 18 x 36/100
Question 22
Discount price = 80 - 80x10/100
Selling price = discount price + discount price x 7/100
use the domain {-4, -2, 0, 2, 4} the codomain [-4, -2, 0, 2, 4} and the range {0, 2, 4} to create a function that is niether one

Answer:
See attachment
Step-by-step explanation:
We want to create a function that is neither one-to-one or on to given that:
The domain is {-4, -2, 0, 2, 4}
The codomain is [-4, -2, 0, 2, 4}
The range is {0, 2, 4}
The function in the attachment is an example of such function.
The function is not one-to-one because there are different different x-value in the domain that has the same y-value in the co-domain.
It is not an on to function because the range is not equal to the co-domain.
