The length of the arc intercepted by a central angle is the ratio of the angle to 360 degrees times the circumference. From the given values above,
S = (30° / 360°) x 2 x π x (6 ft)
S = π
The angle intercepted an arc which measures π feet. The answer is letter A.

The slope for 5 and 2

Yuri [45]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

As we know, slope (m) is equal to tan θ for a straight line :

$\qquad \tt\dashrightarrow \: m = \tan( \theta)$

$\qquad \tt\dashrightarrow \: m = \dfrac{5}{2}$

So, we can say that it's a positive constant slope

professor190 [17]

Answer: an equation that represents the total costs of the gym membership based on the number of months is

y = 25x + 50

Step-by-step explanation:

Let x represent the number of months that Frank makes use of the gym at LA fitness in order to get better in shape.

Let y represent the total cost of using the gym for x months.

He has to pay a one-time enrollment fee of $50 and then membership costs $25 per month. This means that the total cist for x month would be

y = 25x + 50

(7x10*5)x(3x10*2) in standerd form

marishachu [46]

Answer:

21,000

Step-by-step explanation:

This is more of straightforward multiplication, so I cannot explain much! If you want me to try to do more, then just comment.

(7 * 10 * 5) * (3 * 10 * 2)

= (70 * 5) * (30 * 2)

= (350) * (60)

= 21,000

Thusly, in standard form, the equation given is $\boxed{21,000}$ .

Hope this helps! (:

Answer:

0.7823 = 78.23% probability that the response time is between 3 and 9 minutes.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 7.2 minutes and a standard deviation of 2.1 minutes.

This means that $\mu = 7.2, \sigma = 2.1$
