So here’s a example and formula
Answer:
0
Step-by-step explanation:
First, you plug -9 into g(x) and you get g(-9) = - 1. After that, you solve f(-1), which you then reach the solution of 0 by solving.
Answer:
1, 2 and 4 option - Yes
3 option - No
Step-by-step explanation:
<u>Definition: </u>Vertical angles are the angles opposite each other when two lines cross.
By the definition options
- they are formed by intersecting lines,
- they are opposite to each other
are true.
Vertical Angles Theorem states that vertical angles are congruent. Thus, option
is true.
Option
- they are always supplementary
is false, because supplementary are angles that add up to 180°, but vertical angles can have different measures which do not add up to 180°.
(3.2 • 10^8)(1.3 • 10^9)
= 4.16 • 10^17 in scientific notation
The circumference of the circle based on the equilateral triangle is 63mm.
<h3>How to calculate the circumference?</h3>
The side of the triangle is 20mm. The radius will be:
= 20/2 = 10
The circumference of the circle will be:
= 2πr
= 2 × 3.14 × 10
= 63
In conclusion, the circumference is 63mm.
