Answer:
[tex]Total = 625x^3 + 125x^2 + 125x[/tex]
Step-by-step explanation:
Given
[tex]Flowers = 25x^2 + 5x + 5[/tex]
[tex]Unit\ price = 5x[/tex]
Required
The total price for 5 days
First, calculate the total for a day.
[tex]1\ day = Unit\ price * Flowers[/tex]
[tex]1\ day = 5x * (25x^2 + 5x + 5)[/tex]
Open bracket
[tex]1\ day = 125x^3 + 25x^2 + 25x[/tex]
For 5 days, the total will be.
Total = days * sales of a day
So, we have:
[tex]Total = 5 * [ 125x^3 + 25x^2 + 25x][/tex]
[tex]Total = 625x^3 + 125x^2 + 125x[/tex]
A ship travels due west for 83 miles . It then travels in northwest direction for 111 miles and ends up 165 miles from its original position. To the nearest tenth of a degree how many degrees north of west did it turn when it changed direction? Show your work.
*see attachment for the diagram of the information given
Answer:
115.8°
Step-by-step explanation:
Due west = 83 miles
Northwest = 111 miles
Distance to its original position = 165 miles
Let x represent the degree north of west that it turned when it changed direction which is the opposite angle of 165 miles.
Thus, to find x, we'd apply the Law of Cosine which is given as:
c² = a² + b² - 2ab*cos C
Where,
C = x
a = 83 miles
b = 111 miles
c = 165 miles
Plug in the values
165² = 83² + 111² - 2*83*111*Cos x
27,225 = 19,210 - 18,426*Cos x
27,225 - 19,210 = - 18,426*Cos x
8,015 = -18,426*Cos x
8,015 = -18,426*Cos x
8,015/-18,426 = Cos x
-0.434983176 = Cos Cmx
Cos x = -0.434983176
x = cos^{-1}(-0.434983176)
x = 115.784223°
x = 115.8°

no files plssssssss!
Answer:
Your answer is the first option, (2,-1).
Step-by-step explanation:
All you have to do is plug the (x,y) values into both equations, then solve and see if they're true.
For the first equation, plug x (aka 2) and y (aka -1) into the places they belong.
2x + y = 3 would become 2(2) + (-1) = 3 after putting the values in the right spots.
Solve.
2(2) = 4.
4 + (-1) = 3
3 = 3.
That means that (2,-1) is the solution for the first equation, however it also needs to be true for the second. Do the same thing and plug the values in their designated spots.
y = x - 3 will become -1 = 2 - 3.
2 - 3 = -1.
So you're left with:
-1 = -1, which means again that (2,-1) is also the solution for that equation.

Molly is using a map with a scale of 12 = 40 molly needs to travel from point x to point y how far does she need to travel
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Ratio=12:40[/tex]
Required
Determine the actual distance between x and y
The question is incomplete, as the scale distance between x and y is not given.
To solve this, we make assumptions.
A scale measurement is represented as:
[tex]Ratio = Scale : Actual[/tex]
So, we have:
[tex]Scale : Actual = 12 : 40[/tex]
Express as fraction
[tex]\frac{Actual}{Scale} = \frac{40}{12}[/tex]
Make Actual, the subject
[tex]Actual = \frac{40}{12} * Scale[/tex]
Now, assume that the distance between x and y is 60 (on the scale), the actual distance traveled will be:
[tex]Actual = \frac{40}{12} * 60[/tex]
[tex]Actual = 200[/tex]

What are the possible numbers of minutes she has used her phone in a month?
Usem for the number of minutes, and solve your inequality for m.
DO
Answer:
1312.5 minutes
Step-by-step explanation:
For her phone service, Lucy pays a monthly fee of $25, and she pays an additional $0.06 per minute of use. The least she has been charged in a month Is $103.72
What are the possible numbers of minutes she has used her phone in a month?
Use m for the number of minutes, and solve your inequality for m.
The term least = ≥ = greater than or equal to
Our inequality equation is given as:
$25 + $0.06 × m ≥ $103.72
25 + 0.06m ≥ 103.72
0.06m ≥ 103.72 - 25
0.06m≥ 78.75
m ≥ 78.75/0.06
m ≥ 1312.5 minutes
The possible number of minutes she used is 1312.5 minutes
The solid shown below is made by combining two rectangular prisms. What is the total volume of the solid?
Answer:
The question has a picture attached of both rectangular prisms which I have attached and solved.

The sum of 3 consecutive odd number is 53 What is the second number in the sequence
Answer:
Step-by-step explanation:
Let
x = first odd number
x + 2 = second odd number
x + 4 = third odd number
Total = 53
53 = x + (x + 2) + (x + 4)
53 = x + x + 2 + x + 4
53 = 3x + 6
53 - 6 = 3x
47 = 3x
x = 47/3
x = 15.7
x + 2 = second odd number
15.7 + 2 = 17.7
Second number = 17.7

→XxKim02xXWrite the trigonometric expression in terms of sine and cosine, and then simplify. cot()/sin()-csc()
Answer:
First, we know that:
cot(x) = cos(x)/sin(x)
csc(x) = 1/sin(x)
I can't know for sure what is the exact equation, so I will assume two cases.
The first case is if the equation is:
[tex]\frac{cot(x)}{sin(x)} - csc(x)[/tex]
if we replace cot(x) and csc(x) we get:
[tex]\frac{cot(x)}{sin(x)} - csc(x) = \frac{cos(x)}{sin(x)} \frac{1}{sin(x)} - \frac{1}{sin(x)}[/tex]
Now let's we can rewrite this as:
[tex]\frac{cos(x)}{sin(x)} \frac{1}{sin(x)} - \frac{1}{sin(x)} =\frac{cos(x)}{sin^2(x)} - \frac{1}{sin(x)}[/tex]
[tex]\frac{cos(x)}{sin^2(x)} - \frac{sin(x)}{sin^2(x)} = \frac{cos(x) - sin(x)}{sin^2(x)}[/tex]
We can't simplify it more.
Second case:
If the initial equation was
[tex]\frac{cot(x)}{sin(x) - csc(x)}[/tex]
Then if we replace cot(x) and csc(x)
[tex]\frac{cos(x)}{sin(x)}*\frac{1}{sin(x) - 1/sin(x)} = \frac{cos(x)}{sin(x)}*\frac{1}{sin^2(x)/sin(x) - 1/sin(x)}[/tex]
This is equal to:
[tex]\frac{cos(x)}{sin(x)}*\frac{sin(x)}{sin^2(x) - 1}[/tex]
And we know that:
sin^2(x) + cos^2(x) = 1
Then:
sin^2(x) - 1 = -cos^2(x)
So we can replace that in our equation:
[tex]\frac{cos(x)}{sin(x)}*\frac{sin(x)}{sin^2(x) - 1} = \frac{cos(x)}{sin(x)}*\frac{sin(x)}{-cos^2(x)} = -\frac{cos(x)}{cos^2(x)}*\frac{sin(x)}{sin(x)} = - \frac{1}{cos(x)}[/tex]

Answer:
the slope is 3/2
Step-by-step explanation:
Answer:
1.5
Explanation:
the slope of the line can be calculated by rise ÷ run, or the vertical increase divided by the horizontal increase. we can see that from the point (1,-3) to the point (3,0), the line increases vertically by 3 and horizontally by 2.
since the line is moving upwards, it is positive.
thus, the slope of the line is 3 ÷ 2 = 1.5.

Kate conducts a survey at her middle school to determine the students' favorite sport. Which sampling method would best produce a representative sample of the population?
Incomplete question. The missing options read;
a. Kate surveys every 8th student from a roster of the choir members.
b. Kate surveys the football team.
c. Kate surveys seventh-grade students.
d. Kate surveys every 4th student entering the school.
Answer:
d. Kate surveys every 4th student entering the school.
Step-by-step explanation:
Interestingly, after careful examination of all the listed sampling methods, none except option d would best produce a representative sample of the population.
This is because;
in the first, second, and third option, none of them evenly represents the entire school population; meaning it fails to produce a representative sample of the population.
However, if Kate surveys every 4th student entering the school, then chances of getting a representative sample of the entire school population are very likely; as different grade level students would likely be entering into the school when the survey activity is taking place.

Answer:
Variación de temperatura: 310°C
Step-by-step explanation:
La variación de temperatura entre la temperatura más baja conocida en la tierra (-273°C = 273° bajo cero) y la temperatura promedio de la tierra (37°C) será el valor absoluto de la diferencia de estos dos valores, es decir:
Variación de temperatura: |-273°C - 37°C|
Variación de temperatura: |-310°C|
Como el valor absoluto de un número negativo es su valor positivo (|-x| = x)
Variación de temperatura: 310°CA bag contains 6 green marbles, 5 blue, and 9 red. What is the probability that you will select two green marbles from the bag?
