Answer:

$d=10568.76rads$

Step-by-step explanation:

From the question we are told that:

Angular Velocity $\omega=580rpm=>60.74rads/sec$

Time $t=2.9mins=>174sec$

Generally the equation for distance d is mathematically given by

$d=\omega*t$

$d=60.74*174$

$d=10568.76rads$

What is the value of the function when x = 2?

VARVARA [1.3K]

Answer: The answer is -2

Step-by-step explanation:

To make this easier, first draw or imagine a vertical line at x=2

Find where the vertical line and the graph intersects.

Draw or imagine that point of intersection.

Now, draw or imagine a horizontal line that goes through the point of intersection.

That horizontal line tells us the the value of the function by passing through that mark that says "-2"

The function's value at x=2 is -2.

the lengths of the side of a rectangular window have the ratio 1.7 to 1 the area of the window is 2,720 sqaure inches what are d

nignag [31]

Answer:

$Lenght: 68\ in\\\\Width: 40\ in$

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

$A=lw$

Where "l" is the lenght and "w" is the width.

You know that the ratio of the sides of the rectangular window is:

$1.7:1$

Then, let be $x$ the width (in inches) of the rectangular window and $1.7x$ the lenght (in inches) of the rectangular window.

Knowing that the area of the window is 2,720 square inches, you can know that:

$(1.7x)(x)=2,720$

Now you must solve for "x" in order to find the width:

$(1.7x)(x)=2,720\\\\1.7x^2=\\\\x=\sqrt{\frac{2,720}{1.7} }\\\\x=40$

Finally, the lenght is:

$1.7x=1.7(40)=68$

9 students volunteer for a committee. How many different 7-person committees can be chosen?

lorasvet [3.4K]

If order doesn't matter (e.g. all the positions in the committee are essentially identical) then the number of possible choices is $\dbinom97=\dfrac{9!}{7!(9-7)!}=36$ .

Graph y -5 equals -2/3(x +9)

Akimi4 [234]

Answer:

y = -2/3x - 1

Step-by-step explanation:

Let's solve for y.

y−5=−2/3(x+9)

Step 1: Add 5 to both sides.

y−5+5=−2/3x−6+5

y=−2/3x−1
