Hey there! Here is your answer:

102,600 would be in a group. 19 would not be in a group.

Step-by-step explanation:

We can figure this out by doing 102,619 divided by 57. This gives us:

1,800 R 19

Now we need to multiply 1800 by 57 to see how many residents there are:

1,800 x 57 = 102,600

Our remainder tells us how many residents would not fit into a group. Since our remainder is 19, 19 would not be in a group.

I hope this helps!

Answer:

f(x) = y

Step-by-step explanation:

Think of it as a input-output function machine, where you give a number as input to the machine, and the you get a number as the output from the machine. The input is x which goes inside of the ( )'s, and the output is f(x). The output 'f(x)' is sometimes called the y-value because y = f(x).

For example f(-2) = 4. The number you give to the machine is -2 since it's the x-value and the number is in ( )'s. The output number the machine gives back to you is 4, which is the y-value.

Answer:

A. Rosa

Step-by-step explanation:

Since both measurements of time are using the same units, minutes, we can simply compare them and decide which one is the smallest number. The smallest number represents who took the least amount of time and therefore shows who completed their lab first.

35.7 _ 36.5

35.7 < 36.5

Rosa with 35.7 minutes, completed her lab first.

Answer:

Rosa would have finished first

Step-by-step explanation:

If Rosa finished her chemistry lab in 35.7 minutes and Dale in 36.5 it doesn't matter about the decimal 35 comes before 36 therefore Rosa finished first.

Step-by-step explanation:

We have that the  first term of the progression is

b=4

From the Question we are told that

Third terms of a Geometric Progression is 48

Sum of third and fourth terms is 144

[tex]x_3+x_4=144[/tex]

Generally the equation for the common ratio  is mathematically given as

   [tex]\frac{br^2+br^3}{br+br^2}=\frac{144}{48}\\\\\frac{br^2+br^3}{br+br^2}=3[/tex]

Answer:

Step-by-step explanation:

The vector AP is in the same directionas AB but its length is 1/3 of AB

No AB = (7-(-2)) i + (-2-4)j = 9i -6j.

It follows that AP = (1/3)(9i-6j) = 3i - 2j.

Now OP = OA +AP = (-2i + 4 j ) + (3i-2j) = i + 2j

So P(1,2).

Answer:

-4%   -1/25

Step-by-step explanation:

To convert a decimal to a percentage, multiply it by 100.

-0.04 * 100 = -4

To convert a decimal to a fraction, put the decimal as a fraction over 1 and multiply until the numerator (top number) is a whole number and then simplify.

[tex]\frac{-0.04}{1}[/tex] x [tex]\frac{100}{100}[/tex] = [tex]\frac{-4}{100}[/tex]

-4/100 simplified = -1/25 (because 4 goes into 100 25 times)

An equation for the nth term of the arithmetic sequence is aₙ=9-3n.

An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is aₙ=a+(n-1)d.

The given arithmetic sequence is 6,3,0,-3,...

Here, first term a=6 and common difference is 3-6=-3

Substitute a=6 and d=-3 in aₙ=a+(n-1)d, we get

aₙ=6+(n-1)(-3)

aₙ=6-3n+3

aₙ=9-3n

Therefore, an equation for the nth term of the arithmetic sequence is aₙ=9-3n.

Hello there!

Formulas

[tex] \displaystyle \large{ \sin (2 \theta) = 2 \sin \theta \cos \theta} \\ \displaystyle \large{ \cos (2 \theta) = \begin{cases} 2 { \cos}^{2} \theta - 1 \\ 1 - 2 { \sin}^{2} \theta \\ { \cos}^{2} \theta - { \sin}^{2} \theta \end{cases}}[/tex]

First, we have to find cos(theta). We know that the theta lies in Q3 which is negative for both sin and cos. To find cos, you can use the identity or Pythagoras.

Recall

[tex] \displaystyle \large \tt{ \sin \theta = \frac{opposite}{hypotenuse} } \\ \displaystyle \large \tt{ \cos \theta = \frac{adjacent}{hypotenuse} }[/tex]

Finding cos, I will use Pythagoras.

Recall Pythagorean

[tex] \displaystyle \large{ {a}^{2} + {b}^{2} = {c}^{2} }[/tex]

From sin = -1/6

[tex] \displaystyle \large{ {1}^{2} + {b}^{2} = {6}^{2} } \\ \displaystyle \large{1 + {b}^{2} = 36 } \\ \displaystyle \large{ {b}^{2} = 36 - 1 } \\ \displaystyle \large{ {b}^{2} = 35 } \\ \displaystyle \large{ {b} = \sqrt{35} }[/tex]

b is our adjacent. Hence,

[tex] \displaystyle \large{ \cos \theta = \frac{ \sqrt{35} }{6} }[/tex]

Since theta is in Q3, cos < 0 or in negative.

[tex] \displaystyle \large{ \cos \theta = - \frac{ \sqrt{35} }{6} }[/tex]

Finding sin(2theta)

[tex] \displaystyle \large{ \sin \theta = - \frac{ 1 }{6} }[/tex]

Hence,

[tex] \displaystyle \large{ \sin 2 \theta = 2( - \frac{ 1 }{6} )( - \frac{ \sqrt{35} }{6}) } \\ \displaystyle \large{ \sin 2 \theta = ( - \frac{ 1 }{3} )( - \frac{ \sqrt{35} }{6}) } \\ \displaystyle \large{ \sin 2 \theta = \frac{ \sqrt{35} }{18} }[/tex]

Recall

Finding cos(2theta)

The cos of 2theta has multiple formulas. All of them are same and also identity to each others.

I will be using the first one as it only involves cos, not sin.

[tex] \displaystyle \large{ \cos \theta = - \frac{ \sqrt{35} }{6} }[/tex]

Therefore,

[tex] \displaystyle \large{ \cos2 \theta = 2 { ( - \frac{ \sqrt{35} }{6} )}^{2} - 1 } \\ \displaystyle \large{ \cos2 \theta = 2 (\frac{ 35}{36}) - 1 } \\ \displaystyle \large{ \cos2 \theta = \frac{ 35}{18} - 1 } \\ \displaystyle \large{ \cos2 \theta = \frac{ 35}{18} - \frac{18}{18} \longrightarrow \boxed{\frac{17}{18} }}[/tex]

Answer:

  similar by AA

Step-by-step explanation:

Each of the smaller right triangles shares an acute angle with the original (largest) triangle, so all of the triangles are similar by the AA similarity postulate.

[tex]\text{x}=5\\\\2\text{x}^2+\text{x}(100-15\text{x})=2\cdot5^2+5\cdot(100-15\cdot5)=\\\\=2\cdot25+5\cdot(100-75)=50+5\cdot25=\\\\=50+125=\boxed{175}[/tex]

[tex] \boxed{ \boxed{ \mathrm{ \: \: \: \: \: \: \: \: \: 175 \: \: \: \: \: \: \: \: \: }}}[/tex]

Plugging the value of x as 5 in the given expression we get,

[tex] \hookrightarrow \: 2 {x}^{2} +x (100 - 15x)[/tex]

[tex] \hookrightarrow \: 2(5) {}^{2} + 5(100 - (15 \times 5))[/tex]

[tex] \hookrightarrow \: (2 \times 25) + 5(100 - 75)[/tex]

[tex] \hookrightarrow \: 50 + 5(25)[/tex]

[tex] \hookrightarrow \: 50 + 125[/tex]
