1 answer:

3 0

2x^2 - 7

we can plug any values of x into this The domain is All Real x.

The graph will be a parabola opening upwards with a minimum value when x = 0 and f(x) will be = -7

so the range is f(x) <= -7 or (-∞, -7]

If the length of segment AC equals 58, what is the length of the midsegment DE

Delicious77 [7]

Answer:

B) 29

Step-by-step explanation:

Given:

AC= 58

Point D and E are the midpoints of side AB and BC Respectively.

Solution:

According to Midpoint theorem which states:

"The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side."

$\therefore$ DE= $\frac{1}{2}$ AC

DE= $\frac{58}{2} =29$

Hence length of DE is 29.
