Yes because 5 and 4 are greater than 2.
a2 +b2 = c2
2^2 + 4^2 = 5^2
4 + 16 =25

Pythagorean theorem proves that those side lengths create a triangle as well.

Answer:

x = 6 cm

Step-by-step explanation:

Given ratio of sides of similar figures = a : b , then

ratio of areas = a² : b²

Here ratio of areas = 5 : 45 = 1 : 9 , so

ratio of sides = $\sqrt{1}$ : $\sqrt{9}$ = 1 : 3

Thus side of B is 3 times side of A

x = 3 × 2 = 6 cm

Find the remainder when (x3 – 2) is divided by (x – 1). what is the remainder?

KengaRu [80]

By remainder theorem:

f(x) = x³ - 2

factor, x - 1 = 0

x = 1,

Remainder = f(1)

f(x) = x³ - 2

f(1) = 1³ - 2 = 1 - 2 = -1.

Hence remainder is = -1.

Which equation represents the line passing through the points (3, 2) and (–9, 6)?

prisoha [69]

(3,2),(-9,6)
slope = (6 - 2) / (-9 - 3) = -4/12 = -1/3

y = mx + b
slope(m) = -1/3
use either of ur points...(3,2)....x = 3 and y = 2
now we sub into the formula and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b
so ur equation is : y = -1/3x + 3 <==

Consider a solid spherical ball made of wood. Suppose a hole is bored (drilled) vertically through the center of the ball and th

lbvjy [14]

Answer:

The volume of solid is 268.08 inches cube.

Step-by-step explanation:

The solid spherical ball has height 8 inches that means the diameter of the sphere is 8 inches. So, the radius will be the half of diameter. Thus, radius is 4 inches.

Now use below formula to find the volume of solid sphere.

$Volume = \frac{4}{3}\pi r^{2} \\Volume = \frac{4}{3}\pi (4)^{2} \\Volume = 268.08 \ in^{3}$

Therefore, the volume of solid is 268.08 inches cube.
