Answer:
I dont think so I would look at it as how did they get the -2
Use trigonometric ratios.
Use angle(19)
Adjacent side of angle measure 19 is X
The hypotenuse is 21.
Use the cosine
Cos(19)=x/21
Plug in calculator
(21)cos(19)=19.85
Round to the nearest tenth. Which means the 8 rounds up to 9.
Answer: 19.9
Answer:
B
Step-by-step explanation:
In this problem we have points of the form (x^0,y^0) cama Y0 what we must do is replace it of appointing a function Y = 3^x replace x^0 with x and y^0 with 1. The point belongs to the function only if the right side of the equality is equal to the left side
Absolute value is a positive number
So -7-1 = -6
