In 8 days, the temperature dropped 12 degrees. If the temperature changed at the same rate for all the days what was the change in temperature per day?
Answer:
1.5° per day
Step-by-step explanation:
Given that :
Total temperature change = drop by 12°
Number of days for the change = 8 days
Rate at which temperature changed is constant
Change in temperature per day :
Total change in temperature / number of days
12° / 8
= 1.5° per day

Answer:
A. 100 per deposit
Step-by-step explanation:
for every one deposit made, you see your y value increasing by 100
Answer: Choice A is correct
=================================================
Explanation:
Each time x goes up by 1, y goes up by 100 (eg: from 50 to 150, so 150-50 = 100).
We then say,
slope = rise/run
slope = (change in y)/(change in x)
slope = (100)/(1)
slope = 100
The rate of change is $100 per deposit
------------------------------
We could also use the slope formula. Pick any two points on the diagonal line. Let's say we picked (1,150) and (3,350)
m = (y2-y1)/(x2-x1)
m = (350-150)/(3-1)
m = (200)/(2)
m = 100
Or we could pick (0,50) and (1,150) as our two points
m = (y2-y1)/(x2-x1)
m = (150-50)/(1-0)
m = (100)/(1)
m = 100
Either way, the slope is m = 100.

plz tell formula of Cotθ plz fully explain
Answer:
1. cos(2π + θ) = cosθ
2. tan(2π + θ) = tanθ, cot(2π + θ) = cotθ.
explanation:
cot(2π + θ) = cotθ. The Trigonometric ratios of angle 2π - θ: Thinking of θ as an acute angle, 2π -θ ends in the 4th Quadrant where only cosine is positive. 2π -θ means going 1 full turn from A to A and then returning to the M' that means as much as θ.
Answer: cos(2π + θ) = cosθ, tan(2π + θ) = tanθ, cot(2π + θ) = cotθ.

can someone help me
Answer:
93°
Step-by-step explanation:
90+38= 128. all angles of a triangle always equal 180. so the last angle inside the triangle is 52°. WYZ is a straight line, so 180-52 will get you the measure of the angle in question, which is 93°

Does anyone know the correct choice for this question? If its correct ill mark you as the best answer choice!
Answer:
Therefore, the line's equation and the correct slope will be:
[tex]y = 3, m = 0[/tex]
Therefore, option J is correct.
Step-by-step explanation:
As the line is perpendicular to the y-axis means the line is parallel to the x-axis.
i.e. m = 0As the line passes through (2, 3)so according to the point slop form
[tex]y-y_{1} =m(x-x_{1} )[/tex]
[tex]y - 3 = 0 (x - 2)[/tex]
[tex]y - 3 = 0 - 0[/tex]
[tex]y = 3[/tex]
Therefore, the line's equation and the correct slope will be:
[tex]y = 3, m = 0[/tex]
Therefore, option J is correct.

2.5
B)
20
C)
40
D)

What is the solution to the equation below?
2(x – 3) = 2x + 5
show your work
Answer:
2(x - 3) = 2x + 5
Multiply out the left side:
2x - 6 = 2x + 5
Subtract 2x from both sides:
-6 = 5
Since this is impossible, this "equation" cannot be solved.

The Sandoval family paid $180 for 2 adult tickets and 3 child tickets to an amusement park. The Martinez family paid $105 for 1 adult and 2 child tickets to the same park. What is the price of a child ticket?
Answer: The cost of a child ticket is $30
Step-by-step explanation:
Let's define the variables:
A = price of an adult ticket
C = price of a child ticket
We know that:
"The Sandoval family paid $180 for 2 adult tickets and 3 child tickets to an amusement park."
This means that:
2*A + 3*C = $180
and
"The Martinez family paid $105 for 1 adult and 2 child tickets to the same park."
This means that:
1*A + 2*C = $105
Then we have a system of equations:
2*A + 3*C = $180
1*A + 2*C = $105
To solve this, the first step is to isolate one variable in one of the equations, i will isolate A in the second equation:
A = $105 - 2*C
Now we can replace this in the other equation:
2*($105 - 2*C) + 3*C = $180
Now let's solve this for C, the price of a child ticket.
2*($105 - 2*C) + 3*C = $180
$210 - 4*C + 3*C = $180
$210 - C = $180
-C = $180 - $210
-C = - $30
C = $30
The cost of a child ticket is $30
Function f(x) represents the population of bacteria x hours after 9 a.m. What does F(2)-F(1) represent?
Answer:
f(2)-f(1) => Difference between the count of bacteria between 11AM and 10AM
Step-by-step explanation:
Here x is the number of hours after 9AM
f(2) means the count of bacteria after 2 hours of 9AM i.e. at 11AM
f(1) means the count of bacteria after 1 hour of 9AM i.e. at 10 AM
f(2) - f(1) will give us the difference between the count of bacteria between 11 AM and 10 AM
Hence,
f(2)-f(1) => Difference between the count of bacteria between 11AM and 10AM
