Answer:

x ≤ 1

Step-by-step explanation:

Swapping sides of the inequality requires reversing its sense.

If 1 is greater than x, then x is less than 1.

Find all values of x such that sin 2x = sin x and 0 ≤ x ≤ 2π.

jarptica [38.1K]

Hello :
 sin 2x = sin x and 0 ≤ x ≤ 2π.
all solutions :
2x= x +2kπ or x= π -x +2kπ ..... k in : Z
x = 2kπ or : x = π/2 + kπ
but :
0 ≤ x ≤ 2π
all values of x such that sin 2x = sin x and 0 ≤ x ≤ 2π are :
k = 0 : x=0 , x= π/2
k=1 : x=2 π , x=3π/2

Help please?!?!?!?!?!?!?

nadezda [96]

Answer:

Choice D is correct answer.

Step-by-step explanation:

We have given two function.

f(x) =2ˣ+5x and g(x) = 3x-5

We have to find the addition of given two function.

(f+g)(x) = ?

The formula to find the addition, we have

(f+g)(x) = f(x) + g(x)

Putting given values in above formula, we have

(f+g)(x) = (2ˣ+5x)+(3x-5)

(f+g)(x) = 2ˣ+5x+3x-5

Adding like terms, we have

(f+g)(x) = 2ˣ+8x-5 which is the answer.

A college student Earned $6500 during summer vacation working as a waiter. The student invested Part of the money at 10% and the

Juliette [100K]

Answer:

The amount invested at 10% rate is $ 2200

Step-by-step explanation:

Given as :

The total amount earn by student = $6500

The total interest received at the end of year = $607

Let the amount invested at 10% rate = $x

So, The amount invested at 9% rate = ($6500 - $x)

Let the time for which money invested = 1 year

Now from Simple Interest method :

SI = $\frac{principal\times Rate\times Time}{100}$

Or, SI_1 + SI_2 = $\frac{x\times 10\times 1}{100}$ + $\frac{(6500-x)l\times 9\times 1}{100}$

Or, SI_1 + SI_2 = $(\frac{10x}{100})+\frac{(6500-x)\times 9}{100}$

Or, $607 × 100 = 10x + (6500-x) × 9

Or, $60700 = 10x- 9x + 58500

Or, $60700 - $58500 = x

Or , 2200 = x

∴ x = 2200

So, The amount invested at 10% rate = $x = $ 2200

Hence The amount invested at 10% rate is $ 2200 Answer
