Step-by-step explanation:

(2*PI*r_A*h_A) /(2*PI*r_*h_B)=440/3960

r_B=n*r_A,h_B=n*r_A

then n=3

r_A=10

then r_B=30

Answer:

76.5 cm²

Step-by-step explanation:

Given the triangles are similar , then

ratio of sides = a : b , so

ratio of areas = a² : b²

Here ratio of sides = 9 : 13.5 = 2 : 3

ratio of areas = 2² : 3² = 4 : 9

let x be the area of Δ DEF and using proportion

[tex]\frac{4}{34}[/tex] = [tex]\frac{9}{x}[/tex] ( cross- multiply )

4x = 306 ( divide both sides by 4 )

x = 76.5

The area of Δ DEF = 76.5 cm²

Answer:

840 is the correct answer

Answer:

-4/5, -3/7, 1/4, 2/3

Step-by-step explanation:

The last one is the greatest as a positive but because it's both the greatest positive but a negative it is the smallest. Since 2/3 is closest to 1 and is positive it would be the greatest. -3/7 is a smaller value than 1/4 as it's closer to 0 than 1/4 is.

Answer:Group

Step-by-step explanation:

Vertical is group and horizontal is period

Answer: Group

Step-by-step explanation:

For a general quadratic equation, we want to find the equations for the vertex (h, k).

The values of the vertex are:

We start with the general quadratic equation:

f(x) = a*x^2 + b*x + c

To find the x-value of the vertex (h in this case) we need to find the zero of the first derivate of f(x) (because the vertex is a minimum/maximum of the function).

We have:

f'(x) = 2*a*x + b

We solve:

f'(h) = 0 = 2*a*h + b

        -b/(2*a) = h

So we just found the value of h.

To find the value of k, the y-value of the vertex, we need to evaluate the function in the x-value of the vertex, we will get:

k = f(h) = a*( -b/(2*a))^2 + b*( -b/(2*a)) + c

k = b^2/(4a) - b^2/(2a) + c

Then, concluding, we have:

11/9 is the smallest number, sqrt of 5 is 2.2, sqrt of 11 is 3.3, sqrt of 20 is 2*sqrt 5, than 2^3 is the greatest number.

Answer:

m = 55

Step-by-step explanation:

Choose 2 ordered pairs on the number line; i chose (0,125) and (2,235)

The formula for slope (m) is m = y2 - y1 / x2 - x1

In this problem, it would be:

m = 235 - 125 / 2 - 0

m = 110/2

m = 55

Answer:

Slope = 2 and y-intercept = 8

Step-by-step explanation:

Use slope formula

m=y2-y1/x2-x1

m=16-12/4-2

m=4/2

Simplify

m=2

To find the y-intercept use point slope formula

y-y1=m(x-x1)

y-12=2(x-2)

y-12=2x-4

Add 12 to both sides

y=2x+8

So, 8 is the y-intercept or (0,8)

(3.) 2x^3-4x^2-x + (14/(x+6))

Step-by-step explanation:

The expression for the division of polynomials is obtained as  (2x³- 4x²- x) + 14/(x + 6).

The remainder theorem states that that when a polynomial p(x) is divided by another polynomial x + a, then the remainder obtained is given as the value of the polynomial at x = -a which is written as p(-a).

The given problem can be solved by remainder theorem as follows,

Suppose p(x) = 2x⁴ + 8x³- 25x²- 6x + 14.

Now, when p(x) is divided by x + 6, the remainder is given as,

p(-6) = 2 × -6⁴ + 8 × -6³ - 25 × -6² - 6 × -6 + 14

⇒ p(-6) = 14

Thus, by division lemma the following equation can be written as,

2x⁴ + 8x³- 25x²- 6x + 14 = (x + 6)(2x³- 4x²- x) + 14

⇒ (2x⁴ + 8x³- 25x²- 6x + 14) ÷ (x + 6) = (2x³- 4x²- x) + 14/(x + 6)

Hence, the equivalent expression is given as (2x³- 4x²- x) + 14/(x + 6).
