Find an angle between 0° and 360° that is coterminal with the angle 2595°.
Answer:
The angle between 0° and 360° that is co-terminal with the angle 2595° is 75°
Step-by-step explanation:
To find the angle between 0° and 360° that is coterminal to a given angle use this rule
The angle that is co-terminal to Ф = Ф - n × 360, where
Ф is the given anglen is the number of the complete turns∵ The given angle is 2595°
∴ Ф = 2595°
→ To find n divide Ф by 360 and equate n by the whole number only
∵ 2595 ÷ 360 = 7.2083333
→ That means the number of complete turns is 7
∴ n = 7
→ Substitute the values of Ф and n in the rule above
∵ The angle that is co-terminal to 2595° = 2595 - 7 × 360
∴ The angle that is co-terminal to 2595° = 2595 - 2520
∴ The angle that is co-terminal to 2595° = 75°
∴ The angle between 0° and 360° that is co-terminal with the angle
2595° is 75°
How long will it take a car to accelerate from 15.2 m/s to 23.5 m/s if the car has an average acceleration of 3.2 m/s2?
Answer:
t=2.59s
Explanation:
v=23.5m/s u=15.2m/s a=3.2m/s^2 t=? using equation v=u+at t=(v-u)/a t= (23.5-15.2)/3.2=8.3/3.2=2.59s
REALLY NEED HELP WITH THIS
Answer:
62.28
Step-by-step explanation:
Ok, so since we know the radius of the circle and the area of the shaded region, we can find the fraction of the whole circle the shaded region is, and apply that to the total circumference to find the length of the arc.
1. area of whole circle = 17^2*3.14 = 907.46in^2
2. 529.35/907.46 = 0.5833314967
3. circumference of whole circle = 2*3.14*17 = 106.76
4. length of arc = 106.76*0.5833314967 = 62.2764705877 --> 62.28

The graph below compares plant height to the age of the plant, in weeks.
A graph titled Plant Height has Weeks on the x-axis and Height (inches) on the y-axis. A line has a regression equation of y = 1.3 x minus 0.8.
Based on the graph, which is the best prediction of the height of the plant at 5 weeks?
4 inches
5 inches
6 inches
7 inches
Answer:
if you look at the graph and follow up from 5 weeks it almost hits the point 6 inches so you would say six inches the answer is 6 inches
Step-by-step explanation:
The best prediction of the height of the plant at 5 weeks is 6 inches, the correct option is C.
What is a Graph?Graph is a mathematical representation of relation between two objects.
The graph shows the comparison of the plant height to the age of the plant, in weeks.
The x axis has number of weeks.
The y axis has height in inches.
The regression equation that represent the graph is
y = 1.3x - 0.8
A regression equation is used to find the relation between the data, if there exists.
The regression equation is of the form Y = a+bX, Y is the dependent variable and X is the independent variable.
The prediction of the height of the plant at 5 weeks has to be done.
On observing the graph and drawing a straight line at x = 5 on the graph, the point at which it intersects is y ≈ 6 inches.
Your question seems incomplete, the complete question is attached with the answer.

Answer:
it takes 2.56 (or 2 14/25) months
Step-by-step explanation:
Edmond has $45 in his saving account. He wants to purchase a computer that costs $768. He starts to babysit for his cousin and gets paid $90/week. He plans to spend some money and deposit $75/ week in his account. Define a variable and write an equation and solve to find how many months it takes for him to buy the computer. Assume that every month has 4 weeks
Even though Edmond is getting $90 a week, he's only depositing $75
Based on this information your equation would be:
75w = $768 where w = week
To solve that divide 75 by 768
w = 10.24 or 10 6/25
If there are 4 weeks in a month then your new equation would be
w/4 = m where m = months
To solve this, substitute w for 10.24 or 10 6/25
(10.24)/4 = m
m = 2.56 or 2 14/25

the average elecation of new Orleans, Louisiana is -8 feet. the elevation of madras hometown is 8 feet higher then new Orleans.what is the elevation of madras hometown?
Answer:
The elevation of Madras hometown is 0 ft ( representing the surface level elevation)
Step-by-step explanation:
Here, we want to get the elevation of madras hometown
From the question, we are told that Madras home town is 8 feet higher
-8 feet symbolizes a height that is below the surface
Adding 8 to -8 , we have an elevation of -8 + 8 = 0 feet
What this means is that the elevation is exactly at the surface

Adding which terms to 3x^2y would result in a monomial? Check all that apply
Answer:
[tex]-12x^2y[/tex] and [tex]4x^2y[/tex]
Step-by-step explanation:
Given
[tex]3x^2y[/tex]
Required
What added term would make it a monomial
Options
[tex]3xy[/tex]
[tex]-12x^2y[/tex]
[tex]2x^2y^2[/tex]
[tex]7xy^2[/tex]
[tex]-10x^2[/tex]
[tex]4x^2y[/tex]
[tex]3x^3[/tex]
The given expression, [tex]3x^2y[/tex] has 2 variables; x and y
x has a power of 2 and y has a power of 1.
This implies that, the next term to be added must have y to the power of 1 and x to the power of 2
From the list of given options, only 2 options satisfy this condition.
[tex]-12x^2y[/tex]
[tex]4x^2y[/tex]
When these two terms are added to [tex]3x^2y[/tex], the result is a monomial.
i.e.
[tex]3x^2y - 12x^2y = -9x^2y[/tex]
[tex]3x^2y + 4x^2y = 7x^2y[/tex]
