Step-by-step explanation:

The length of arc s is calculated as

circumference of circle × fraction of circle

The central angle subtended by arc s is 360° - 114° = 246° then

arc s = 2πr × [tex]\frac{246}{360}[/tex]

        = 2π × 9 × [tex]\frac{41}{60}[/tex]

        = 18π × [tex]\frac{41}{60}[/tex]

        ≈ 38.64 ( to 2 dec. places )

Answer:

  D.  5

Step-by-step explanation:

The discontinuities in the tangent function are found where the argument matches π/2 +nπ for some integer n. If x has the range [0, 4], then x² has the range [0, 16]. We're looking for the number of values of n that satisfy ...

  0 ≤ π/2 +nπ ≤ 16

Dividing by π gives ...

  0 ≤ 1/2 +n ≤ 16/π

Subtracting 1/2, we have ...

  -1/2 ≤ n ≤ 4.59...

The integer values of n in this range are {0, 1, 2, 3, 4}. There are 5 of them, hence ...

Answer:

a=1/3

Step-by-step explanation:

24a=8

Divide both sides by 24, and you will get a=8/24

Divide both the numerator and denominator by 4, and you will get 2/6, which is equivalent to 1/3.

Answer:

a = 1/3

Step-by-step explanation:

Divide both sides of the equation by the same term(24)

24a/24 and 8/24 = a = 1/3

maybe something is missing here, but that is the representation of what you wrote.

The volume of a right circular cone that has a height of 10.6 m and a base with a diameter of 18.5 m is,

V = 949.76cm³

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Height of cone = 10.6 m

Diameter of cone = 18.5 m

Hence, We can solve for radius as;

= 18.5/2

= 9.25

We know that;

Volume of a right circular cone is,

V = 1/3(πr²h)

Here, r = 9.25, h = 10.6, π = 3.14,

Hence, We get;

V = 1/3(3.14)(9.25)²(10.6)

V = 1/3(3.14)(85.5625)(10.6)

V = 1/3(2847.86225)

V = 949.287417

V = 949.76cm³

Thus, The volume of a right circular cone that has a height of 10.6 m and a base with a diameter of 18.5 m is,

V = 949.76cm³

Answer:

0.9

Step-by-step explanation:

14/15 = 0.933333333  IF:

1. You first change it into a decimal by dividing the numerator by the denominator.

       14 ÷ 15

2. You will get a recurring decimal.

     0.933333333

3. The first digit after the decimal is in the position of the 'tenths'

      0.9

4. You should use only two digits after the decimal to calculate

      0.93

5. Since the number 3 is less than five, it will change into a zero and get eliminated.

            ∴ The answer will be = 0.9

Answer:

-4

Step-by-step explanation:

We are given the equation:-

[tex] \displaystyle \large{x + Cy = \frac{1}{4} }[/tex]

Since we wants to find the value of C that makes the line pass y-intercept which is -1/16.

When we talk about y-intercept, our x-value remains 0 and y-value remains any real number.

It can be expressed as (0,b) point where b is any real numbers.

What we have to do is to substitute (0,-1/16) or x = 0, y = -1/16 in the equation so we can find the value of C.

Thus:-

[tex] \displaystyle \large{x + Cy = \frac{1}{4} } \\ \displaystyle \large{0 + C( - \frac{1}{16} ) = \frac{1}{4} } \\ \displaystyle \large{ - \frac{ C}{16} = \frac{1}{4} }[/tex]

Multiply both sides by GCF.

[tex] \displaystyle \large{ - \frac{ C}{16} = \frac{1}{4} } \\ \displaystyle \large{ - \frac{ C}{16} (16)= \frac{1}{4} (16)} \\ \displaystyle \large{ - C= 4 } \\ \displaystyle \large{ C= - 4 }[/tex]

Therefore, C = -4

Step-by-step explanation:

I Had Also Taken The Test And It Was 1 7/18 In Mixed Numbers.

The expression 4(19 + e2) + 3f at e = 13 and f = 16 is 804.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, we have to Evaluate the expression 4(19 + e2) + 3f when e = 13 and

f = 16 is the same as replacing the numerical values of e and f in the expression

4(19 + e2) + 3f which is,

= 4(19 + 13²) + 3×16.

= 4(19 + 169) + 48.

= 4(189) + 48.

= 756 + 48.

= 804.

Step-by-step explanation:

Step-by-step explanation:

Given the general form of the absolute value function, y = a|x - h| + k

The value of k determines how far up or down the parent function is translated. If k is positive, the function is translated k units up.  If k is negative, the function is translated |k | units down.

The value of h determines how far left or right the parent function is translated. If h is positive, the function is translated h units to the right.  If h is negative, the function is translated |h | units to the left.

The value of a determines whether the graph opens up or down.

The value of a also makes the parent function wider or narrower.
