Answer:

(x-8)(x+6)

Step-by-step explanation:

We have been given a trinomial x^2-2x-48. We are asked to factor the given trinomial.

We will use split the middle term method to factor the given trinomial. We need two numbers, whose sum is -2 and product is -48. We know two such number are -8\text{ and }6.

Split the middle term:

x^2-8x+6x-48

Make two groups:

(x^2-8x)+(6x-48)

Factor greatest common factor of each group:

x(x-8)+6(x-8)

Use distributive property  backwards:

(x-8)(x+6)

Therefore, factorized form of the given trinomial would be (x-8)(x+6).

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line. y2
HACTEHA [7]

This question is incomplete, the complete question is;

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line. y2 = 2x, x = 2y; about the y-axis

Answer:

V = π (512/15)

Step-by-step explanation:

Given that;

region of rotation

y² = 2x, x = 2y

Region is rotated about y-axis as shown in the image

for the point of intersection,

y²/2 = 2y

y² - 4y = 0

y(y-4) = 0

∴ y = 0, y = 4

so the region lies in 0 ≤ y ≤ 4

Now cross section area of washer is

A(y) = π(outer radius)² = π(inner radius)²

A(y) = π(2y)² - π(y²/2)²

A(y) = π(4y²) - π(y⁴/4)

A(y) = π(4y² - (y⁴/4))

now volume of the solid of revolution is

V = ⁴∫₀ A(y) dy

V = ⁴∫₀ π(4y² - (y⁴/4))dy

V =  π {4⁴∫₀ y² - 1/4⁴∫₀y⁴ dy }

V = π { 4/3 [y³]₀⁴ - 1/20 [y⁵]₀⁴ }

V = π { 4/3 [4]₀⁴ - 1/20 [4]₀⁴ }

V = π { 4/3 [64]₀⁴ - 1/20 [1024]₀⁴ }

V = π { 256/3 - 1024/20 }

V = π { (5120 - 3072) / 60 }

V = π (512/15)

Elan Coil [88]

Answer:

42/81 or 0.5185185

Step-by-step explanation:

7/9 × 2/3

The hcf of 9 and 3 is 9

7/9 × 2/3

2/3 × 3= 6/9

7/9× 6/9 = 42/81 or 0.5185185
