A bicycle wheel has a radius of 28 cm. what is the circumference of the wheel?

Answers

Answer:

176 cm

Step-by-step explanation:

You want the circumference of a wheel with a radius of 28 cm.

Circumference

The circumference of a circle is given by ...

C = 2πr

For r = 28 cm, this is ...

C = 2π(28 cm) = 56π cm ≈ 176 cm

The circumference of the wheel is 56π cm, about 176 cm.

The point-slope form of the equation for a line can be written as

... y = m(x -h) +k . . . . . . . for a line with slope m through point (h, k)

Your function gives

... f'(h) = m

... f(h) = k

a) The tangent line is then

... y = 5(x -2) +3

b) The normal line will have a slope that is the negative reciprocal of that of the tangent line.

... y = (-1/5)(x -2) +3

_____

You asked for "an equation." That's what is provided above. Each can be rearranged to whatever form you like.

In standard form, the tangent line's equation is 5x -y = 7. The normal line's equation is x +5y = 17.

Step-by-step explanation:

Suppose you roll a number cube. What is the theoretical probability of rolling a 2

Answers

Answer: $(1)/(6)$

Step-by-step explanation:

We know that a cube has six faces , if we roll a cube then we have chances to roll six different faces with six different number if it is not biased.

Let the number on cube be 1,2,3,4,5,6.

Thus total outcomes = 6

Then the theoretical probability of rolling a 2 is given by :-

$P(2)=\frac{\text{favorable outcome}}{\text{total outcomes}}\n\n\Rightarrow\ P(2)=(1)/(6)$

if theres six sides to the dices then the answer will be 1/6
