The diagonals of a quadrilateral QRST intersect at P(-1,3). QRST has vertices at Q(3,6) and R(-4,5). What must be the coordinate

erica [24]

S = (-5,0)

T = (2,1)

Step-by-step explanation:

Step 1 :

Given

Q = (3,6) and R = (-4,5). P = (-1,3)

Let S be (a,b) and T be (c,d)

The diagonals of a parallelogram bisect each other. so in order to ensure that QRST is a parallelogram, P must be the mid point of the diagonals QS and RT.

Step 2 :

P is the midpoint of QS

So we have (3+a) ÷ 2 = -1 and (6 + b) ÷ 2 = 3

=> 3 + a = -2 and 6 + b = 6

=> a = -5 and b =0

So S should be (-5,0)

Step 3 :

P is the midpoint of RT

So we have (-4+c) ÷ 2 = -1 and (5 + d) ÷ 2 = 3

=> -4+ c = -2 and 5 + d = 6

=> c = 2 and d =1

So T should be (2,1)

Step 4 :

Answer :

S = (-5,0)

T = (2,1)

Answer:

593 $mm^{2}$

Step-by-step explanation:

3.14 × $17^{2}$ = 907.46

3.14 × $10^{2}$ = 314

907.46 - 314 = 593.46

The fuel efficiency of one type of car is recorded in a scatterplot where the amount of gas used, x (in gallons), is paired with

sukhopar [10]

Answer:

The y-intercept is 0, which represents the amount of gas used when 0 miles are traveled. The slope is 28, which represents the miles that can be traveled with 1 gallon of gas

Step-by-step explanation:

Let

x----> the amount of gas used in gallons

y ---> the distance traveled in miles

we have

$y=28x$

This linear equation represent a direct variation

The y-intercept is the value of y when the value of x is equal to zero

For x=0, y=0

That means ----> The y-intercept is 0, which represents the amount of gas used when 0 miles are traveled

The slope is $m=28\ \frac{miles}{gallon}$

That means ----> The slope is 28, which represents the miles that can be traveled with 1 gallon of gas

Find the product and represent in the simplest form of 12/17 × 3/8

laila [671]

Answer:

9/34

Step-by-step explanation:

I find when multiplying fractions, its easier to separate them into the numerator and denominator.

So we have 12 x 3, and 17 x 8

12 x 3 = 36

17 x 8 = 136

So we have 36/136

Simplified, that is 9/34
