What is the area of this triangle?
mafiozo [28]

We use the vertical side as the base: it is a vertical segment, so it's length is the difference of the y coordinates of its endpoints:

b = y_2-y_1

The height would be the segment starting from (x_3,y_3), perpendicular to the base. Since this is a horizontal segment, its length is the difference of the x coordinates of its endpoints:

h = x_3-x_1

So, the area is given by

A = \dfrac{bh}{2} = \dfrac{(y_2-y_1)(x_3-x_1)}{2}

Will give brainliest answer, there has to be two answers to give one of you the brainliest
Oksi-84 [34.3K]

Answer:

C

Step-by-step explanation:

({8}^{ { - 9})^{ \frac{ - x}{9} } }

when putting a power to another power, then these two powers are multiplied.

so, -9 × (-x/9) = (-9 × -x) / 9 = 9x/9 = x

so, this reduces to the original

{8}^{x}

and therefore C is the right answer.

The table shows the travelling time to work of 50 people.
Crank

Answer:

24.8 mins

Step-by-step explanation:

Time > timemark > frequency

0 – 10 > 10/2 = 5 > 5

10 – 20 > (10+20)/2 = 15 > 15

20 – 30 > (20+30)/2 = 25 > 13

30 – 40 > (30+40)/2 = 35 > 10

40 – 50 > (40+50)/2 = 45 > 7

The mean time for the 50 people is given by:

Mean = summation (mid time x frequency) / total frequency

Mean = [5x5 + 15x15 + 25x13 + 35x10 + 45x7] / 50

Mean = [25 + 225 + 325 + 350 + 315] / 50

Mean = 1240 / 50

Mean = 24.8 mins
