Answers

Answer 1

Answer:

Answer is tan(20 degrees) so, D.

Step-by-step explanation:

Answer 2

As a single trigonometric ratio (2tan(10 degrees))/(1 - tan² (10 degrees)) = tan 2x = tan 20 degree

What is Trigonometric Ratios ?

The ratios of sides of a right angled triangle that can be used to determine the value of angles and sides are called Trigonometric Ratios.

The expression given is

(2tan(10 degrees))/(1 - tan² (10 degrees))

By the property of Tan 2x

Tan 2x = 2tanx /(1 - tan² x)

Therefore from the formula ,

x = 10 in the given expression

Therefore as a single trigonometric ratio (2tan(10 degrees))/(1 - tan² (10 degrees)) = tan 2x = tan 20 degree

Option D is the correct answer.

Answer:

I dont think the way you wrote it was right.

Step-by-step explanation:

Answer:

f(x) = 2x(x - 5)(x -2)(x + 1)

Step-by-step explanation:

Given

f(x)= 2x^4 -12x^3 +6x^2 +20x

Factoring in steps

f(x)= 2x^4 -12x^3 +6x^2 +20x =2x(x^3 - 6x^2 + 3x + 10) =2x(x^3 - x^2 - 2x - 5x^2 + 5x + 10)2x(x - 5)( x^2 - x - 2) = 2x(x - 5)(x -2)(x + 1)

The graph of g is the graph of f translated horizontally 3 units to the left. If f(x) = 2x + 1 what is an equation for the function g?
Group of answer choices

g(x) = 3(2x + 1)

g(x) = 2(x + 3) + 1

g(x) = 2(x – 3) + 1

g(x) = 2x + 1 + 3

Answers

Answer: g(x) = 2(x + 3) + 1

Step-by-step explanation:

When we have an horizontal translation of A units (A is a positive real number) to the right, we write this as:

g(x) = f(x - A)

If the translation is to the left, then we have:

g(x) = f(x + A).

In this case, we have a translation to the left, and A = 3, then:

g(x) = f(x + 3)

And we know that:

f(x) = 2x + 1

g(x) = f(x + 3) = 2*(x + 3) + 1 = 2x + 6 + 1 = 2x + 7

g(x) = 2x + 7

Answer:

536 19/50 cm

Step-by-step explanation:

Volume = length*width*height

It's a cube so the length, width, and height are  8 1/8 cm's

8 1/8 = 65/8

65/8 * 65/8 * 65/8 = 274625/512

274625/512 = 536 19/50 cm

A rectangular yard has a width that is 10 feet longer than the width . If the the area of the yard is 600 squared feet , find the dimension of the yard

Answers

Answer:

length = 30 feet and width = 20 feet

Step-by-step explanation:

Let l is length and b is width of a rectangular yard. The area of a rectangle is given by :

A = lb ..(1)

A rectangular yard has a length that is 10 feet longer than the width.

length, l = 10+b ...(2)

ATQ,

Put the value of l in equation (1),

[tex](10+b)b=600\\\\10b+b^2=600\\\\b^2+10b-600=0\\\\b^2+30b-20b-600=0\\\\b(b+30)-20(b+30)=0\\\\(b+30)(b-20)=0\\\\b=-30\ \text{feet}\ \text{and}\ b=20\ \text{feet}[/tex]

Width can't be negative. The width is 20 feet.

Put the value of b is equation (2),

l = 10+20

l = 30 feet

Hence, the length and width are 30 feet and 20 feet.
