Point B has rectangular coordinates (-5, 12)
Write the coordinates (r, e) for point B. (O in degrees)
Answer:
(13, -67.4°)
Step-by-step explanation:
In the general case, for a point (x, y), the same point written in polar coordinates is (r, θ), such that:
r = √(x^2 + y^2)
θ = Atg(y/x)
Then if we have the point with coordinates (-5, 12)
The polar coordinates will be:
r = √((-5)^2 + 12^2) = 13
θ = Atg(12/-5) = -67.4°
Then the polar coordinates are:
(13, -67.4°)

Which statement about the linear factors and zeros of a quadratic function is always
true?
A. The constants of the linear factors are the opposite of the function's zeros.
B. A function's zeros can be determined by setting each linear factor equal to 0 and
solving.
C. If a function's zero is an integer, then the coefficient of the variable in the linear factor
must be one.
D. Multiplying the constants of the linear factors gives one of the function's zeros, and
adding the constants gives the other zero.
An architect built a scale model of a
sports stadium using a scale in which 3
inches represents 45 feet. The height of
the sports stadium is 180 feet. What is the
height of the scale model in inches?
FOR BRAINLIST!!
Answer:
The right answer is D ( 12 in )
3 in - - - - > 45 feet
x in - - - - > 180 feet
-----------------------------
45*x=3*180 - - > 45*x=540 - - > x=540/45=12
For the past 40 days, Naomi has been recording the number of customers at her restaurant between 10:00 a.m. and 11:00 a.m. During that hour, there have been fewer than 20 customers on 25 out of the 40 days.
What is the experimental probability there will be **20 or more customers** on the forty-first day? Include it as fraction, decimal and percent.
Answer:
the experimental probability for 20 or more customersis 37.5%
Step-by-step explanation:
Given that
The recording of the customers would be in between 10:00 AM to 11:00 PM
In this, they have been fewer than 20 customers on 20 out of the 40 days
We need to find out the experimental probability for 20 or more customers
So,
= (40 - 25) ÷ (40)
= 15 ÷ 40
= 37.5%
Hence, the experimental probability for 20 or more customers is 37.5%

The ratio of the height to the base of a triangle is 3:4. If the base is 24 cm, what is its
area?
Answer:
height = 18 cm
Step-by-step explanation:
Let the height be 'x'
3 : 4 :: x : 24
Product of means = product of extremes
4 *x = 24 * 3
[tex]x = \frac{3 * 24}{4}\\\\x = 3 * 6\\\\x = 18[/tex]
Answer:
216cm^2
Step-by-step explanation:
If the ratio of height to base is 3:4 then
height = (3/4)*base
height = (3/4)*24cm = 18cm
Area = base*height/2 = 24cm * 18cm / 2 = 24cm * 9cm = 216cm^2
It takes Scott 3 times longer to paint a house than it takes James. If they work together, they can paint the house in 13 hours. Write equation that could be used to solve for the amount of hours it takes each of them to paint the house alone.
Answer:
I believe it is 13 - 3x
Step-by-step explanation:
Since we dont know how long it takes Scott to paint the house, we use x in its place. We are subtracting to find out how many hours it takes James. Once you get that answer divide by 3.
The equation that should be used to solve for the amount of hours should be considered to be 13-3x.
Calculation of the equation;Since
It takes Scott 3 times longer to paint a house than it takes James. And, they work together, they can paint the house in 13 hours.
So here we assume x to paint the house
So here the equation be like 13-3x.

A small country emits 130,000 kilotons of carbon dioxide per year. In
a recent global agreement, the country agreed to cut its carbon
emissions by 3.1% per year for the next 10 years. In the first year of the
agreement, the country will keep its emissions at 130,000 kilotons and
the emissions will decrease 3.1% in each successive year. How many
total kilotons of carbon dioxide would the country emit over the course
of the 10 year period, to the nearest whole number?
Answer:1132858
Step-by-step explanation:
The total carbon dioxide the country emit over the course of the 10 year period would be 1,132,858 kilotons.
What is rate of decrease?
The rate of decrease is a constant amount of deduction from a fixed or primary amount.
Here, the carbon dioxide emits by the country per year is 130,000 kilotons.
The rate of decrease of the carbon dioxide emission per year would be 3.1%.
In the 1st year, the carbon dioxide emission = 130,000 kilotons.
In the 2nd year, the carbon dioxide emission = 130,000 × (100-3.1)/ 100 kilotons = 125,970 kilotons.
In the 3rd year, the carbon dioxide emission = 125,970 × (100-3.1)/ 100 kilotons = 122,064.93 kilotons.
In the 4th year, the carbon dioxide emission = 122,064.93 × (100-3.1)/ 100 kilotons = 118,280.92 kilotons.
In the 5th year, the carbon dioxide emission = 118,280.92 × (100-3.1)/ 100 kilotons = 114,614.21 kilotons.
In the 6th year, the carbon dioxide emission = 114,614.21 × (100-3.1)/ 100 kilotons = 111,061.17 kilotons.
In the 7th year, the carbon dioxide emission = 111,061.17 × (100-3.1)/ 100 kilotons = 107,618.27 kilotons.
In the 8th year, the carbon dioxide emission = 107,618.27 × (100-3.1)/ 100 kilotons = 104,282.1 kilotons.
In the 9th year, the carbon dioxide emission = 104,282.1 × (100-3.1)/ 100 kilotons = 101,049.35 kilotons.
In the 10th year, the carbon dioxide emission = 101,049.35 × (100-3.1)/ 100 kilotons = 97,916.82 kilotons.
Hence, total carbon dioxide emission by that country over 10 years = (130,000 + 125,970 + 122,064.93 + 118,280.92 + 114,614.21 + 111,061.17 + 107,618.27 + 104,282.1 + 101,049.35 + 97,916.82) kilotons = 1,132,857.77 kilotons ≈ 1,132,858 kilotons.
