Answer:

Below.

Step-by-step explanation:

You find the values of y by substituting the values of x in the expression x^2 + 3x - 1.

So f(-4) = (-4)^2 + 3(-4) - 1 = 16-12-1 = 3

in the same way  f(-3) = -1, f(-2) = -3, f(-1) = -3,

f(0) = -1 and f(1) = 3.

Now plot the points (-4, 3) , (-3, -1) and so on  

Then you can read the values off this graph.

Answer:

graph attached

when y=3,   x=1, x=-4

when x=-3.5, y=-23.75

just input the value of x in the equation:-3.5^2+3(-3.5)-1=-23.75

minimum value is the vertex:(-3/2,-13/2)

The width of a rectangle is 6 2/3 inches. The length of the rectangle is twice its width. What is the perimeter of the rectangle
hichkok12 [17]
A perimeter of a rectangle is:
2(l+w)

They give you the width, but let's convert it to an improper fraction first:
6 \frac{2}{3} =  \frac{20}{3}

The length is twice the width so it is:
\frac{20}{3}*2 =  \frac{40}{3}

Now, we are ready to solve, plug in values in the perimeter formula:
2(  \frac{40}{3}+ \frac{20}{3}) =  2(\frac{60}{3}) =  \frac{120}{3} = 40

So, 40 is your answer.

4^3= 64
2^6= 64

Therefore, n=6.
You can also figure this out if you know that 2^3*2^6=2^9. When you multiply exponents with the same base, add the exponents. 3+6=9

Final answer: n=6

A gyroscope of radius 18 centimeters rotates 35 times per minute. Find the linear velocity of a point on the edge of the gyrosco
Keith_Richards [23]

In one full rotation/revolution, a point on the edge travels a distance equal to the circumference of the gyroscope, or 2<em>π</em> (18 cm) = 36<em>π</em> cm. Convert the angular speed, 36<em>π</em> cm/rev, to linear speed:

(36<em>π</em> cm/rev) • (35 rev/min) = 1260<em>π</em> cm/min ≈ 3958 cm/min
