Sketch one cycle of the sine curve. y = -3 sin 4theta

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

We have been given a function:

$y=-3sin4\theta$

We will compare it with the genral equation which is:

$y=asin bx+c$

Where, a is amplitude and period of function is $(2\pi)/(b)$

In given equation a is -3 and b is 4

So, period of the given equation is:

$(2\pi)/(4)=(\pi)/(2)$

Yo can look at the graph in the attachment.

Answer 2

Answer:

The a is the amplitude and the period of the function is $(2\pi )/(b)$

We have been given a function

$y = -3 sin 4 \theta$

What is the general form of sin wave?

$y=asinbx+c$

We will compare it with the general equation which is

Where a is amplitude and period of the function is $(2\pi )/(b)$

In the given equation a is -3 and b is 4

So, the period of the given equation is:

$(2\pi )/(4) =(\pi )/(2)$

You can look at the graph.

Solve 3x^2 = 6x by rewriting the equation. Show your reasoning.

Answers

Solution of the given equation $3x^(2)=6x$ is x=2 and 0

What is an equation?

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given,

$3x^(2) =6x$

Rewrite the equation

$3x^(2) -6x=0$

Solve the equation

$3x^(2) -6x=0\n3(x^(2) -2x)=0\nx^(2) -2x=0$

Therefore the roots are

x=2 and 0

Hence, solution of the given equation $3x^(2) =6x$ is x= 2 and 0

the volume of a sphere is 950 cubic inches. use the formula for the volume of a sphere, V= 4/3(3.14)(r)ratical 3, to find the radius r to the nearest tenth of an inch.

Answers

Given:
Volume = 950 cubic inches

V = 4/3 π r³ ; where π = 3.14

950 in³ = 4/3 * 3.14 * r³
950 in³ = 4.19 * r³
950 in³ ÷ 4.19 = r³
226.73 in³ = r³
∛226.73 in³ = ∛r³
6.09 = r

The radius is 6.09 or 6.10 inches.

50% of what number is 90?

Answers

The answer would be 180 because if 90 is 50% and that's half of 100 then the other 50% would also be 90 and added together that is 180

to get to 100 percent you have to double the number so when you double 90 you get 180

90+90=180.

Rolex worked 40 hours last week. He had 74 deducted from his earnings for taxes. If he had 286 left after the deduction how much does Rolex earn per hour?

Answers

Answer:

Rolex earns $9 per hour.

Step-by-step explanation:

Let the number of dollars he earns each hour be x.

To create our equation we need to find the total number of dollars he earned before his deduction which is 40x.

Then we know that he got 74 dollars deducted from his total earnings leaving him with 286 which gives us an equation. 40x + 74 = 286

40x - 74 = 286 (Equation)

40x = 360 (Add 74 from both sides)

x = 9 (Divide both sides by 40)
