Consider the following literal equation.
galina1969 [7]

We can solve this in many ways, let's try this one.

T∧2 = 4 pi∧2 * a∧3 / GM    First we will multiply whole equation with variable( or parameter) M and get

M * T∧2 = 4 pi∧2 * a∧3 / G  After that we will divide whole equation with variable ( or parameter )  T∧2 and get

M = 4 pi∧2 * a∧3 / G * T∧2

This is correct answer

Good luck!!!

Numerically estimate the slope of y = f(x) at r = a. 1. f(x) = x^2 - 2x, a = 2 2. f(x) = sin 2x, a = 0
REY [17]

Answer:

1. Slope at a=2 is 2.

2. Slope at a=0 is 2.

Step-by-step explanation:

We need to find the slope of y = f(x) at x = a.

1.

The given function is

f(x)=x^2-2x

It can be written as

y=x^2-2x

Differentiate with respect to x.

y'=2x-2

Substitute x=2 to find the slope of y = f(x) at a=2.

y'=2(2)-2

y'=4-2

y'=2

Therefore the slope of function at a=2 is 2.

2.

The given function is

f(x)=\sin 2x

It can be written as

y=\sin 2x

Differentiate with respect to x.

y'=2\cos 2x

Substitute x=0 to find the slope of y = f(x) at a=0.

y'=2\cos 2(0)

y'=2(1)

y'=2

Therefore the slope of function at a=0 is 2.

What is the solution to –4(8 – 3x) ≥ 6x – 8?
AleksandrR [38]

Answer:

x ≥ 4

Step-by-step explanation:

Given

- 4(8 - 3x) ≥ 6x - 8 ← distribute parenthesis on left side

- 32 + 12x ≥ 6x - 8 ( subtract 6x from both sides )

- 32 + 6x ≥ - 8 ( add 32 to both sides )

6x ≥ 24 ( divide both sides by 6 )

x ≥ 4

Adding and subtracting functions
tangare [24]

Answer:

5x - 1

Step-by-step explanation:

(f + g)(x) = f(x) + g(x), thus

f(x) + g(x)

= 3x - 2 + 2x + 1 ← collect like terms

= 5x - 1
