Find the slope, then use substitute the slope and one of the given points into slope-intercept form.

Slope is change in y over change in x. (7-3)/(-3-1)=-1

Slope-inttercept form is y = mx+b.
3 = -1(1)+b
b=4

y = -x + 4

mote1985 [20]

Answer:

$890.75m^3$

Step-by-step explanation:

Step one:

given data

heigth/depth = 3.5m

radius= 9m

Step two:

The shape is that of a cylinder

Hence the volume of the pool is

$V= \pi r^2h$

substitute

$V= 3.142*9^2*3.5\\\\V=890.75 m^3$

the length of one of the diagonals of a quadrilateral is 10 cm and the particular drawn from the opposite vertices to this diago

loris [4]

Answer:

Therefore the area of the quadrilateral =35 cm²

Step-by-step explanation:

Given, the length of one of diagonal of quadrilateral is 10 cm and perpendicular drawn from the opposite vertices to this diagonal are the length of 2.8 cm and 4.2 cm.

A diagonal divided a quadrilateral into two triangle.

Therefore the area of the quadrilateral

= sum of the area of the triangles

$=(\frac{1}{2}\times 10\times 2.8+ \frac{1}{2}\times 10\times 4.2)$ cm² [ area of a triangle $= \frac{1}{2}\times base\times height$ ]

=35 cm²
