The answer should be 2x -7y is less than or equal to 14. I’m not sure if that’s an answer option. But I couldn’t see it but that’s what I think it should be. I’m sorry if I’m wrong

Given: FPST is a trapezoid, FP=ST, m∠F=45°, PF=8, PS=10 <br><br> Find: The midsegment MN.
kodGreya [7K]

Answer:

4\sqrt{2}+10

Step-by-step explanation:

In trapezoid FPST, FP=ST, then this trapezoid is isosceles, so

m\angle F=m\angle T=45^{\circ}.

Draw the height PH. Triangle FPH is right triangle with two angles of measure 45°. This means that FH=HP. By the Pythagorean theorem,

FH^2+PH^2=PF^2,\\ \\2FH^2=8^2,\\ \\FH^2=32,\\ \\FH=4\sqrt{2}.

Since trapezoid FPST is isosceles, the base FT hasthe length

FT=2FH+PS=8\sqrt{2}+10.

Then the length of the midline is

MN=\dfrac{FT+PS}{2}=\dfrac{8\sqrt{2}+10+10}{2}=4\sqrt{2}+10.

Raj’s bathtub is clogged and is draining at a rate of 1.5 gallons of water per minute. The table shows that the amount of water
Grace [21]

The range of this function is all real numbers such that 0 ≤ y ≤ 40.

<h3>What is a range?</h3>

A range is the set of all real numbers that connects with the elements of a domain. This simply means that, a range is the solution set on the y-axis.

<h3>How to determine the range?</h3>

Based on the table (see attachment), we can logically deduce that when the time (x) is zero (0), the amount of water remaining in the bathtub (y) is 40.

Therefore, the range of this function is all real numbers such that 0 ≤ y ≤ 40.

      A light plane flew from its home base to an airport 255 miles away. With a head wind, the trip took 1.7 hours. The return
ryzh [129]
The speed from home base to airport was:
v=255miles/1.7h\ /:1.7\\v=150mph
The speed from airport to home base was:
v=255miles/1.5h\ /:1.5\\v=170mph
Average speed of plane was:
\frac{170mph+150mph}{2}=160mph
Average speed of wind was:
x\ -\ wind\ speed\ (mph)\\150+x=170-x\ /+x\\150+2x=170\ /-150\\2x=20\ /:2\\x=10
Answer: Average speed of plane was 160mph and average speed of wind was 10mph.

I hope I helped :D
