Pls help me thanks so much

Answer:

y=8x+55

255 gallons

Step-by-step explanation:

Linear equation: y=mx+b

In this equation you can go ahead and start off with your Y intercept (b) which is where you begin and you begin with 55 gallons. As for the m and x section in the linear equation your m is how much it increases at a constant rate in a minute and that will be eight so you can go ahead and put 8 and then X which is the amount of minutes.

To figure out how many gallons there are in 25 minutes you can use the same equation so you can multiply 8 which is the amount of gallons per minute * 25 and that gives you 200 then you can go ahead and add the y-intercept which is 55 and that gives you 255 gallons in 25 minutes.

Answer:

Counting from the top:

fist option

fourth option

fifth option.

Step-by-step explanation:

Any set that has a multiplicative outcome, such that the total number of outcomes is 24.

Remember that if we have a combination of two events, one with N outcomes and the other with M outcomes, the total number of outcomes is:

M*N

This is the main thing we need to see.

Let's analyze each option:

1) flip a coin (2 outcomes)

  flip a coin again (2 outcomes)

  roll a 6 sided dice ( 6 outcomes)

total number of outcomes:

2*2*6 = 24

2) Selecting a number from 1 to 16 (16 outcomes) and rolling a dice of 8 sides (8 outcomes).

The total number of outcomes is:

8*16 = 128

We wanted only 24.

3) Selecting a number from the set {1, 3, 5, 7, 9} (5 outcomes)

   flip a coin (2 outcomes)

   flip the coin again (2 outcomes)

total number of outcomes:

2*2*5 = 20

We wanted 24, we can discard this.

4) Spin the thing (3 outcomes)

   roll an 8-sided dice (8 outcomes)

Total number of outcomes:

8*3 = 24

This is a correct option.

5) Select a card from A to D (4 outcomes)

Roll the thing (6 outcomes)

total number of outcomes:

6*4 = 24

This is a correct option.

6) Select a card from A to N {14 options}

   Roll the thing once (10 outcomes)

Total number of outcomes:

14*10 = 140

We wanted 24, so we can discard this option.

Then the correct options are:

first one, fourth one, and fifth one.

Given:

The relation S is:

[tex]S=\{(4,9),(-9,4),(0,-9),(6,6)\}[/tex]

To find:

The domain and range of S.

Solution:

If a relation is defined by the set of ordered pairs (x,y), then the domain is the set of x-values and range is the set of y-values.

Let R be a relation defined as [tex]R=\{(x,y):x\in R,y\in R\}[/tex], then [tex]Domain=\{x:x\in R\}[/tex] and [tex]Range=\{y:y\in R\}[/tex].

The given relation is:

[tex]S=\{(4,9),(-9,4),(0,-9),(6,6)\}[/tex]

Here, x-values are 4,-9,0,6 and the y-values are 9,4,-9,6.

So, the domain and range of the given relation S are

[tex]Domain=\{-9,0,4,6\}[/tex]

[tex]Range=\{-9,4,6,9\}[/tex]

Therefore, [tex]Domain=\{-9,0,4,6\}[/tex] and [tex]Range=\{-9,4,6,9\}[/tex].

Answer:

[tex]\displaystyle \sin(2\theta)=\frac{2\sqrt{418}}{49}\approx0.8345[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaystyle \cos(\theta)=\frac{\sqrt{11}}{7}[/tex]

Where θ is in QI.

And we want to determine sin(2θ).

First, note that since θ is in QI, all trig ratios will be positive.

Next, recall that cosine is the ratio of the adjacent side to the hypotenuse. Therefore, the adjacent side a = √(11) and the hypotenuse c = 7.

Then by the Pythagorean Theorem, the opposite side to θ is:

[tex]b=\sqrt{(7)^2-(\sqrt{11})^2}=\sqrt{49-11}=\sqrt{38}[/tex]

So, with respect to θ, the adjacent side is √(11), the opposite side is √(38), and the hypotenuse is 7.

We can rewrite as expression as:

[tex]\sin(2\theta)=2\sin(\theta)\cos(\theta)[/tex]

Using the above information, substitute. Remember that all ratios will be positive:

[tex]\displaystyle =2\Big(\frac{\sqrt{38}}{7}\Big)\Big(\frac{\sqrt{11}}{7}\Big)[/tex]

Simplify. Therefore:

[tex]\displaystyle \sin(2\theta)=\frac{2\sqrt{418}}{49}\approx0.8345[/tex]

Answer:

Step-by-step explanation:

A vertical reflection is given by the equation y=−f(x) and results in the curve being "reflected" across the x-axis. A horizontal reflection is given by the equation y=f (−x) and results in the curve being "reflected" across the y-axis. You can see that the reflections are presented in the terms of a function.

As for translations, the function would just increase or decrease based on the translations.  

In translation the graph of function moves certain distance and in reflection the graph of function reflected along the axis of reflection.

"It is a transformation in which the graph of function is moved from one location to another location without changing its size, shape or orientation."

"It is a transformation in which the graph of function is reflected along the line of reflection."

"It defines a relation between input and output values"

Consider a function f(x).

Translations in function f(x):

1) When function f(x) is transformed to f(x) + k, it means function f(x) is translated vertically up by 'k' units.

2) When function f(x) is transformed to f(x) - k, it means function f(x) is translated vertically down by 'k' units.

3) When function f(x) is transformed to f(x + k), it means function f(x) is translated horizontally left by 'k' units.

4) When function f(x) is transformed to f(x - k), it means function f(x) is translated horizontally right by 'k' units.

Now consider reflections in function f(x):

1) When function f(x) is transformed to -f(x) , it means function f(x) is reflected over X-axis.

2) When function f(x) is transformed to f(-x) , it means function f(x) is reflected over Y-axis.

Therefore, in translation the graph of function moves certain distance and in reflection the graph of function reflected along the axis of reflection.

Answer:

[tex]f(x)=9*\frac{5}{3}^x[/tex]

Step-by-step explanation:

When x equals 0, that means a is going to be multiplied by 1 since any number to the power of 0 is 1, so [tex]f(0)=a=9[/tex]. When x equals 1, that means that [tex]f(1) = 9b=15[/tex], so [tex]b=\frac{15}{9} =\frac{5}{3}[/tex]. This means that the equation should be [tex]f(x)=9*\frac{5}{3}^x[/tex].

Step-by-step explanation:

Given:

The pair of similar triangles.

Base of smaller triangle = 10 in

Base of larger triangle = 14 in

To find:

The ratio of the perimeters and the ratio of the areas.

Solution:

Ratio of perimeter of similar triangles is equal to the ratio of their corresponding sides.

[tex]\text{Ratio of perimeters}=\dfrac{10\ in.}{14\ in.}[/tex]

[tex]\text{Ratio of perimeters}=\dfrac{5}{7}[/tex]

[tex]\text{Ratio of perimeters}=5:7[/tex]

The ratio of area of similar triangles is equal to the ratio of squares of their corresponding sides.

[tex]\text{Ratio of areas}=\dfrac{(10)^2}{(14)^2}[/tex]

[tex]\text{Ratio of areas}=\dfrac{100}{196}[/tex]

[tex]\text{Ratio of areas}=\dfrac{25}{49}[/tex]

[tex]\text{Ratio of areas}=25:49[/tex]

Therefore, the ratio of the perimeters is 5:7 and the ratio of the areas 25:49.
