Question

maria [59]

Answer:

y = m x + b equation of a straight line

m m' = -1 condition for perpendicular lines

If y = 4 x - 7 then m = 4 so m' = -.25

Y = -.25 X + A we need to find A

A = Y + .25 * 8 = 2 + 2 = 4

Y = -.25 X + 4

Check:

2 = -.25 * 8 + 4 = -2 + 4 = 2

Find the volume of the given prism.<br><br>Ans:60cm^3

taurus [48]

Answer:

60 cm³

volume of triangular prism : area of base * Length

Given:

side of triangle : 4 cm

side of triangle : 3 cm

angle between 4 cm and 3 cm : 90°

Length : 10 cm

Find area of base:

$\rightarrow \sf \dfrac{1}{2} * side \ 1 \ * side \ 2 \ * \ sin (\theta)$

$\rightarrow \sf \dfrac{1}{2} *\ 4 \ * \ 3 \ * \ sin (90)$

$\rightarrow \sf 6 \ cm^2$

Volume :

A * L

6 * 10

A cylinder with a radius of 6cm and height of 15 cm has a cylindrical cut out of the

suter [353]

Answer:

$V = 518cm^3$

Step-by-step explanation:

Given

$h = 15cm$

$R = 6cm$

$r =5cm$

Required

The volume of the remaining cylinder

Before the cut-out, the cylinder has a volume (V) of:

$V = \pi R^2h$

After the cut-out, the cylinder has a volume of:

$V = \pi [R^2 -r^2]h$

So, we have:

$V = 3.14* [6^2 -5^2]*15$

$V = 3.14* [36 -25]*15$

$V = 3.14* 11*15$

$V = 518cm^3$
