Please Help!!! "What is the area of trapezoid ABCD? Enter your answer as a decimal or whole number in the box. Do not round at a
Alexxx [7]
To find the length of each side of the trapezoid, you need to use the distance formula.
AB = (-3,2) and (1,5)
BC = (1,5) and (7,-3)
CD = (7, -3) and (0, -2)
AD or DA = (0,-2) and (-3,2)
Now, just use the distance formula for each line. Doing so gives us:
AB = 5
BC = 10
CD = 7.071107...
DA or AD = 5
The height is AB, the first base is BC and the second base is CD. We can plug the values for these sides into the trapezoid area formula, which is A = base 1 + base 2 all over 2 times the height. Doing so gives us 37.5 units². Therefore, the answer to your query is 37.5 units². Hope this helps and have a nice day!

The graph shows the results of a race between Parin and Andrew. Both boys begin the race at the same time. Which statements are
vampirchik [111]

Answer:  C, E

The graph shows the results of a race between Parin and Andrew. Both boys begin the race at the same time.

To find the rate of race, we find the slope

We pick two points for Andrew

(0,90)  and (13,0)

Slope = \frac{y_2-y_1}{x_2-x1}=\frac{0-90}{13-0} = -6.9

We pick two points for Parin

(0,100)  and (12,0)

Slope = \frac{y_2-y_1}{x_2-x1}=\frac{0-100}{12-0} = -8.33

Andrew runs the race at the rate of -6.9 yd/s

Parin runs the race at the rate  of -8.33 yd/s

So, Parin runs the race at a faster rate than Andrew



Andrew finishes the race at 13 seconds

Parin finished the rate at 12 seconds

So, Andrew finishes the race 1 s after Parin finishes the race.


Yards from finish line for Parin is 100 yds

Parin is given a 10 yd head start and wins the race.



So , Parin runs a longer race than Andrew.  

Andrew and Parin started the race at time =0

Both of them started at the same time

Find the specified nth term of each geometric sequence.<br><br><br> a4 = 10, r = 2, n = 9
Degger [83]

Answer:

a_{n} = 1.25(2)^{n-1}

Step-by-step explanation:

Geometric Sequence is the sequence in which every digit is the same multiplier of its previous digit.

The formula of Geometric Sequence is: a_{n} = a_{1}(r)^{n-1}

We have given value of 4th term i.e.

a_{4} = a_{1}(2)^{4-1}

⇒ 10 = a_{1} (2)^{3}

⇒ a_{1} = \frac{10}{(2)^{3}}

⇒ a₁ = 1.25

Hence, the nth term of each sequence is: a_{n} = 1.25(2)^{n-1}
