Step-by-step explanation:
f(x) = 2x² + 9
f(5) = 2(5)² + 9
= 2(25) + 9
= 50 + 9
= 59
21^2/0.219 = 2013.69863
2 significant figures are the 20, so the answer is 2000
Parentheses first. 1-4= -3. 4-3=1. 1-2=-1.
The answer is -1.
Answer:
the angle of this is 80 all havevtobdo is add all the sides of the angle
Answer:
The vertex of this equation is (2, -7)
Step-by-step explanation:
In order to find the vertex of this equation we start with the base form of the vertex form.
y = a(x - h) + k
With this equation (h, k) is the vertex. You can see that 2 lines up with h and -7 lines up with k. This shows that (2, -7) is the vertex.
