The number of people playing a new phone app game triples every month. When the app first launched, 800 people started playing the game right away. There are currently 194,400 people playing the game. Write an equation to represent this situation, and determine the number of months, t, that have passed since the app launched.

Answer:

Step-by-step explanation:

First we calculate (-3)÷10 = -0.3

Then 12÷(-0.3) = -40

After that -4 + (-40) = -44

3(-2) = -6

Finally -44 + (-6) = -50

For this case we have that the order of algebraic operations is determined by PEMDAS:

P: Perform any calculation inside the parentheses, making the most internal ones first.

E: Simplify any exponential expressions.

MD: Do all the multiplications and divisions, from left to right, as they appear.

AS: Do all the addition and subtraction, from left to right, as they appear.

Then, we have the following expression:

-4 + 12 ÷ (-3) ÷ 10 + 3 (-2) =

-4-4 ÷ 10 + 3 (-2) =

-4-0.4 + 3 (-2) =

-4-0.4-6 =

-4.4-6 =

-10.4

Answer:

-10.4

Answer:

The range is 19

Step-by-step explanation:

First, you have to order the numbers from least to greatest:

-9.5, -3.1, 3.1, 3.2, 4.7, 4.9, 5.4, 6.3, 9.5

Then, you have to find the difference between the largest number and and smallest number. You do this by subtracting them:

9.5 - (-9.5)= 19

So, the range is 19

Answer:

[tex]P(green)+P(yellow)=\frac{3}{8}+\frac{1}{8}[/tex]

[tex]P(green)+P(yellow)=\frac{1}{4}+\frac{1}{4}[/tex]

[tex]P(green)+P(yellow)=\frac{3}{7}+\frac{1}{14}[/tex]

Step-by-step explanation:

The given probabilities are:

[tex]P(red)=\frac{2}{7}[/tex]

[tex]P(blue)=\frac{3}{14}[/tex]

Their sum is [tex]P(red)+P(blue)=\frac{2}{7}+\frac{3}{14}[/tex]

The probabilities that will complete the model should add up to [tex]\frac{1}{2}[/tex] so that the sum of all probabilities is 1.

[tex]P(green)+P(yellow)=\frac{2}{7}+\frac{2}{7}\ne\frac{1}{2}[/tex]

[tex]P(green)+P(yellow)=\frac{3}{8}+\frac{1}{8}=\frac{1}{2}[/tex]

[tex]P(green)+P(yellow)=\frac{1}{4}+\frac{1}{4}=\frac{1}{2}[/tex]

[tex]P(green)+P(yellow)=\frac{5}{21}+\frac{11}{21}\ne\frac{1}{2}[/tex]

[tex]P(green)+P(yellow)=\frac{3}{7}+\frac{1}{14}=\frac{1}{2}[/tex]

Answer:

According to the information you provided, a probability model includes P(red) = 2/7 and P(blue) = 3/14. The probabilities that could complete the model are P(green) = 5/21 and P(yellow) = 11/21. This is because the sum of all probabilities in a probability model must equal 1. In this case, 2/7 + 3/14 + 5/21 + 11/21 = 1.

For this case we must find the quotient of [tex]x ^ 2 + 11x + 24[/tex] between [tex]x + 4[/tex]

As you can see in the figure, we must build a quotient in such a way that when multiplied by the divisor, we eliminate the terms of the dividend until we reach the remainder.

Answer:

D

Step-by-step explanation:

Value of the function [tex]\lim_{x \to 4} \dfrac {g}{h}(x)[/tex] is zero.

Correct option is b.

Limits are defined as values ​​to which the function approximates the output for given input values. The limit is the unique real numbers. Given a real-valued function "f" and a real number "c", the limit is usually defined as [tex]\lim_{x \to c} f(x) = L[/tex]. We read that "the limit of f of x is equal to L as x approaches c". "lim" represents the limit, and the right arrow indicates that the function f(x) approaches the limit L as x approaches c.

Given functions,

[tex]\lim_{x \to 4} f(x) = 5 , \lim_{x \to 4} g(x) = 0, \lim_{x \to 4} h(x) = -2[/tex]

[tex]=\lim_{x \to 4} \dfrac {g}{h}(x)[/tex]

[tex]=\lim_{x \to 4} \dfrac {g(x)}{h(x)}[/tex]

[tex]=\dfrac{\lim_{x \to 4} g(x)} {\lim_{x \to 4} h(x)}[/tex]

= 0/-2

= 0

Hence, 0 is the value of function [tex]\lim_{x \to 4} \dfrac {g}{h}(x)[/tex] .

Answer:3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Density is mass divided by volume:

ρ = M / V

So mass is density times volume:

M = ρV

If the density is 865 kg/m³ and the volume is 61.25 m³:

M = (865 kg/m³) (61.25 m³)

M = 52981.25 kg

Final answer:

To find the mass of oil in a tank, multiply the tank's volume (61.25 cubic meters) by the oil's density (865 kg/m³), resulting in 52,981.25 kilograms. The mass is not measured in kilometers, which suggests a typo in the original question.

Explanation:

The question concerns the calculation of the mass of oil if its density and the volume of the tank it fills are known. To find the mass, you would multiply the volume of the oil by its density:

Step-by-Step Calculation:

Determine the volume of the oil. In this case, the volume is already given as 61.25 cubic meters.

Identify the density of the oil. According to the question, it is 865 kilograms per cubic meter.

Multiply the volume by the density to get the mass. That is:

61.25 m³ × 865 kg/m³ = 52,981.25 kilograms.

In terms of mass in kilometers, there appears to be a typo, as mass is not measured in distances like kilometers. The correct unit should likely be kilograms.

Answer:

$855355.656503296, but we round to $855355.66

Step-by-step explanation:

Set up an equation where f(x)=650000(1.04)^n. The 1.04 represents the growth because if it were just .04 we wouldn't be including the initial value and it would decay. The 650000 is the initial value, and we put 1.04 to the nth power because it represents the amount of years. To plug in seven years, simply do 650000(1.04)^7 in your calculator.

Answer:

2/5

Step-by-step explanation:

There are 10 marbles and 4 of them are purple. That would give you the fraction 4/10. 4/10 can be simplified to 2/5. So, you have a 2/5ths chance of choosing a purple marble.

The probability of selecting a purple marble from a bag containing 10 marbles, 4 of which are purple, is 2/5.

The question asks: "A bag contains 10 marbles. Four of the marbles are purple. What is the probability you will choose a purple marble from the bag?" To find the probability, you divide the number of favorable outcomes (choosing a purple marble) by the total number of outcomes (all the marbles in the bag). Here, there are 4 purple marbles and 10 marbles in total.

The probability is therefore 4/10, which can be simplified to 2/5. So, the probability of choosing a purple marble from the bag is 2/5.

Answer:

Yes, i believe that the generalization about the measure of a point angle of a star polygon is true.

First we find sum of interior angle of an n-sided star polygon.

number of triangle in a polygon = n - 2

sum of interior angle of a triangle = 180°

sum of interior angle of an n-sided star polygon = ( n - 2 ) × 180°

To find measure of a point angle, we use:

[tex]\frac{|n-2(d)|}{n}[/tex] × 180°                                                            

To find a point angle we eliminate density by multiplying d by 2  in the formula for finding number of triangle, divide the whole by total number of sides and then multiply by the sum of interior angle of triangle(180°).  

Since all the angle of a regular star polygon are equal, we can calculate each pointy interior angle of a regular star polygon using the formula given below:

[tex]\frac{|n-2(d)|}{n}[/tex] × 180°

A.) The graph of f(x) is horizontally compressed.

EXPLANATION

The given absolute value function is

[tex]f(x) = - 6 |x + 5| - 2[/tex]

The parent function is

[tex]y = |x| [/tex]

Since the factor -6 has an absolute value greater than 1, the graph of the given function will be narrower than the graph of the base function.

Hence the graph is horizontally stretched by a factor of 6.

The graph opens downwards because of the negative sign.

Final answer:

To calculate the height of the rectangular prism, we use the formula for volume and the given values to solve for height, resulting in a height of 4.5 inches.

Explanation:

To find the height of a rectangular prism with a given volume where the length is two times the width and the width is known, we use the formula for the volume of a rectangular prism: volume = length × width × height.

Given that the volume is 144 cubic inches, the width is 4 inches, and the length is two times the width, which is 2 × 4 inches = 8 inches, we can substitute these values into the formula:

144 in³ = 8 in × 4 in × height

Next, we need to isolate 'height' by dividing both sides of the equation by the length times the width of the prism:

144 in³ / (8 in × 4 in) = height

144 in³ / 32 in² = height

4.5 in = height

Therefore, the height of the rectangular prism is 4.5 inches.

Answer:

374 miles

Step-by-step explanation:

To see how many miles each gallon gets, divide 102/3 which is 34 meaning there are 34 miles per gallon so if you multiply 34 x 11 gallons it equals 374 miles.

Hope this helps!

To solve this problem, we will use the concept of a unit rate, which in this scenario is the car's miles per gallon (mpg). A unit rate compares a quantity to one unit of another quantity. Here's how to do it step by step:
1. **Find the unit rate (mpg).**
  The car travels 102 miles on 3 gallons of gas. To find out how many miles it travels per gallon, we'd divide the total number of miles by the number of gallons of gas used:
  \[ \text{mpg} = \frac{\text{miles traveled}}{\text{gallons used}} \]
  \[ \text{mpg} = \frac{102 \text{ miles}}{3 \text{ gallons}} \]
  \[ \text{mpg} = 34 \text{ miles per gallon} \]
  So the car travels 34 miles per gallon of gas.
2. **Calculate the distance the car can travel on 11 gallons of gas.**
  Now that we know the car travels 34 miles on one gallon of gas, we can find out how far it travels on 11 gallons by multiplying the mpg by the number of gallons:
  \[ \text{distance} = \text{mpg} \times \text{gallons available} \]
  \[ \text{distance} = 34 \text{ miles/gallon} \times 11 \text{ gallons} \]
  \[ \text{distance} = 374 \text{ miles} \]
So, the car can travel 374 miles on 11 gallons of gas.

No, two ordered pairs in this list have a repeated of the domain element.

We know that the definition of functions tells us that a function [tex]f[/tex] from a set [tex]A[/tex] to a set [tex]B[/tex] is a relation that assigns to each element [tex]x[/tex] in the set [tex]A[/tex] exactly one element [tex]y[/tex] in the set [tex]B[/tex]. The set [tex]A[/tex] is the domain (also called the set of inputs) of the function and the set [tex]B[/tex] contains the range (also called the set of outputs).

So here is important to know the term exactly one element, Why? because if you don't have this, you don't have a function. From the figure, two ordered pairs in this list have a repeated of the domain element. This can be proven by plotting these three points as indicated below. As you can see, the element 4 in the domain matches both 2 and -2 in the range. In conclusion, this relation is not a function.

Answer:

2140

Step-by-step explanation:

Sofia paid a total of $7,440 over 24 months for a motorcycle with a sticker price of $5,300. The interest she paid can be found by subtracting the sticker price from the total amount paid, which comes to $2,140. Hence correct option C.

Sofia bought a motorcycle with a sticker price of $5300. If she paid $310 a month for 24 months, first we need to find out the total amount she paid over the 24 months. To do this, we multiply the monthly payment amount by the number of months:

$310 × 24 = $7,440

Now, to find the amount of interest paid, we subtract the original sticker price from the total amount paid:

$7,440 - $5,300 = $2,140

Therefore, Sofia paid $2,140 in interest.

Answer:

Plan A:

C = $80

C = cost

Plan B:

C = 0.15t + 20

C = cost; t = amount of text messages

Step-by-step explanation:

Let C = cost.

Let t = amount of text messages.

Plan A:

C = $80

Plan B:

C = 0.15t + 20

If the next question asks for you to solve when Plan B will be equal to Plan A, set the two equations equal to each other.

80 = 0.15t + 20

Isolate the variable, t. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 20 from both sides.

80 (-20) = 0.15t + 20 (-20)

80 - 20 = 0.15t

60 = 0.15t

Divide 0.15 from both sides.

(60)/0.15 = (0.15t)/0.15

60/0.15 = t

t = 400

Those who use Plan B must send at least 400 text message to have the same price as Plan A.

Step-by-step explanation:

We can first make y the subject of the formula by multiplying both sides of the equation by -1 ;

y = -x + 0

This is the equation of a line with a slope of -1, the coefficient of x, and passing through the origin.

In order to find three points that solve the equation, we can let x be;

0, 1, 2

then determine the corresponding values of y.

When x = 0, y = -(0) + 0 = 0

When x = 1, y = -(1) + 0 = -1

When x = 2, y = -2 + 0 = -2

Step-by-step explanation:

Given function is [tex]F\left(x\right)=x^2+3x+2[/tex].

Function [tex]F\left(x\right)=x^2+3x+2[/tex] is shifted 2 units right and gives result to a new function g(x).

Now we need to find about what is the equation of g(x).

We know that f(x-h) indicates right shift by "h" units.

So to get 2 units shift, replace x by (x-2) into given function

[tex]g(x)=F\left(x-2\right)[/tex]

[tex]g(x)=(x-2)^2+3(x-2)+2[/tex]

[tex]g(x)=x^2-4x+4+3x-6+2[/tex]
