Well, you can estimate the decimal. For example if you have 1.35678 you can round the three to a four because there is a 5 beside it so the estimated decimal would be 1.4, 1.4 as a fraction would be 1 4/10 which can be simplified down to 1 2/5.
Answer:
f(x) = 2x² + 4x - 16
= 2(x² + 2x) - 16
= 2(x² + 2(x)(1) + 1² - 1²) - 16
= 2(x + 1)² - 2 - 16
= 2(x + 1)² - 18
Vertex: (-1, -18) minimum
Second point can be the y-intercept:
(0, -16)
It should be a concave up
A function has a vertical asymptote where it is not defined, and the logarithm is defined only if its argument is strictly positive: it has a vertical asymptote if its argument is zero, and is not defined if its argument is negative.
So, you have a vertical asymptote where

Answer:
47°
Step-by-step explanation:
In the picture attached, the problem is shown.
When two secants intersect at a point, the angle made is one-half of the difference between the greater arc and the minor arc formed. In this case:
∠ABC = 1/2*(arc DE - arc AC)
Replacing with data from the picture:
∠ABC = 1/2*(142° - 48°)
∠ABC = 47°
Answer:
Melanie is 48 feet away.
Step-by-step explanation:
20% of 25 = 20
20% of 60 = 48
Hopefully it helps, if not I'm sorry...
