Solution:

The value of r is 19.1 cm

Explanation:

We know the arc length formulas which is shown below.

\theta= \frac{s}{r} \\\\r=\frac{s}{\theta}

Here the angle is in radian.

We have been given that

s = 16 cm, θ= 48°

We know that 1 degree = 0.0174533 radian

Hence, 48° = 0.837758 radian

On substituting these values in the formula, we get

r=\frac{16}{0.837758} \\\\r=19.1 \text{ cm}

Therefore, the value of r is r=19.1 cm

I converted θ to radians, then put that and the length of the arc into the formula shown.

Which compound inequality can be represented by the graph below?
steposvetlana [31]

Answer:

The answer to your question is: letter D

Step-by-step explanation:

The interval graph is (5, 9] , open five, nine close. As an inequality this interval is:

                                   5 < x ≤ 9

a) Letter A is incorrect because it suggests that two sections in the graph must be shaded and in this graph there is only one section shaded.

b) Letter B is incorrect because in the graph we observe that before 5 there must be a parenthesis because the point is open and the point in 9 is shaded so it must be follow by a ].

c) Letter c is alos incorrect because it suggests two sections shaded in the graph and it shows only one.

Hi, What is the lowest positive integer greater than 1, which when divided by 5 or 8 leaves a remainder of 1
ludmilkaskok [199]
Very interesting question!

Let's try to get something that would work for just 5 for now.
Any of these numbers would leave a remainder of 1 when divided by just 5:
6, 11, 16, 21, 26, 31, 36, 41, 46, 51, 56, 61, 66, 71, 76, 81, 86, ...
Notice that they all look like 5*(something) + 1. Basically, they are all multiples of 5 plus 1.

Let's see what would work for just 8:
9, 17, 25, 33, 41, 49, 57, 65, 73, 81, 89, ...

Are there any matches... AHA! It's 81. This is the lowest positive integer greater than 1 that follows the rule for both 5 and 8.

Describe how you would convince a friend that sin(x + y) does not equal sin x + sin y.
Citrus2011 [14]

Answer:

Step-by-step explanation:

PEMDAS

anything done in the parentheses comes first

so you have to add first then multiply

this is not the distributive property unless the two numbers in parentheses are not like terms
