A can is in the shape of a right circular cylinder. The circumference of the base of the can is 12 inches, and the height of the
MariettaO [177]

Answer:

the length of the stripe is 20.82inches

Step-by-step explanation:

given

height of can = 5in

circumference = 12in

π = 3.142

the circumference of the base = 2πr = 12

                radius of base = 1.91in

if the stripe wind once round the can (circumference length), it will start from the radius base to the radius top.

the total length of the stripe = 2radius + circumference of can + height

= 2(1.91) + 12 + 5 = 20.82inches

Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined
Annette [7]

Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is x=1 .

<u>Step-by-step explanation:</u>

Here we have to Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined . Let's find out:

We know that for any two points given as P(x_1,y_1),Q(x_2,Y_2)  slope of line is determined by :

⇒ Slope = \frac{y_2-y_1}{x_2-x_1}

According to question we have two points as  P(1,-1),Q(x,7) ∴

⇒ Slope = \frac{y_2-y_1}{x_2-x_1}

⇒ Slope = \frac{7-(-1)}{x-1}

But slope is undefined which is only possible when denominator is zero i.e.

⇒ x-1=0

⇒ x=1

Therefore , Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is x=1 .

Find the midpoint of a line segment whose endpoints are (7, 6) and (2, 3).
Lelu [443]

Answer:

(9/2, 9/2)

Step-by-step explanation:

midpoint formula = (x1 + x2/2, y1 + y2/2)

(7,6) is x1 and y1.

(2,3) is x2 and y2.

Solve:

x-coordinate= (7+2)/2 = 9/2 or 4.5

y-coordinate= (6+3)/2 = 9/2 or 4.5

your final answer is (9/2, 9/2)

decimal form = (4.5, 4.5)

a rule for an example of a nonlinear function that fits the following description. when d is 4, r is 9, and r is a function of d
Anika [276]
Some possibilities:
r = (9√d)/2, so f(d) = <span>(9√d)/2
r = 9d^2/16, so f(d) = </span><span>9d^2/16</span>
r = 9(2^d)/16, so f(d) = 9(2^d)/16

These are examples of non-linear functions of d which fit the description. I think that is what you are asking, but comment if I'm wrong?
