What is the slope of the line whose equation is 5x+2y=10 ?
A. 2/5 C. -2/5
B. 5/2 D. -5/2
Please Help!!
Answers
Answer:
D
Step-by-step explanation:
You can rewrite the equation into slope intercept form and you get Y=10-5x/2 (The whole problem is being divided by 2).
You can leave -5/2 as it is because it's a lot easier to plot the point using Rise over Run or Rise/Run.

the formula of ONE INTERIOR ANGLE of a REGULAR polygon.
Answers
Answer:
180° - (360/n)°, where n is the number of sides of the polygon.
Step-by-step explanation:
Polygon has n sides.
Divide the polygon radially into n congruent, isosceles triangles.
For each triangle:
vertex angle = (360/n)°
sum of base angles = 180° - vertex angle = 180° - (360/n)°
Each interior angle of the n-gon = 180° - (360/n)°
find an angle between 0 degrees and 360 degrees that is coterminal with -240
Answers
The angle between 0 degrees and 360 degrees that is coterminal with -240 is 120 degrees
What are Coterminal angles?Two angles in standard position are called coterminal angles if they have the same terminal side.
When 360 degrees is added to a given angle or when 360 degrees is subtracted from a given angle, we get an angle that is coterminal with the given angle.
Now,
We are to determine an angle between 0 degrees and 360 degrees that is coterminal with -240
To do this, we will add 360 degrees to the given angle
That is,
-240° + 360° = 120°
Hence, the angle is 120 degrees.

A model for consumers' response to advertising is given by the equation N(a)=2600 + 470ln (a) Where N(a) is the number of units sold, a is the amount spent on advertising, in thousands of dollars, & a≥1.
Required:
a. How many units were sold after spending $1,000 on advertising?
b. Find N′(a).
c. Find the maximum value, if it exists.
d. Find lim a→[infinity] N′(a).
Answers
Answer:
a. \(N(1)=2600\)
b. \(N'(a) = 470/a\)
c. N(a) has no maximum value, max N'(a) = 470 (when a = 1)
d. lim a→[infinity] N′(a) = 0
Step-by-step explanation:
a.
the variable 'a' is the amount spent in thousands of dollars, so $1,000 is equivalent to a = 1. Then, we have that:
\(N(1)=2600 + 470ln(1)\)
\(N(1)=2600 + 470*0\)
\(N(1)=2600\)
b.
To find the derivative of N(a), we need to know that the derivative of ln(x) is equal (1/x), and the derivative of a constant is zero. Then, we have:
\(N'(a) = 2600' + (470ln(a))'\)
\(N'(a) = 0 + 470*(1/a)\)
\(N'(a) = 470/a\)
c.
The value of 'ln(a)' increases as the value of 'a' increases from 1 to infinity, so there isn't a maximum value for N(a).
The maximum value of N'(a) is when the value of a is the lower possible, because 'a' is in the denominator, so the maximum value of N'(a) is 470, when a = 1.
d.
When the value of 'a' increases, the fraction '470/a' decreases towards zero, so the limit of N'(a) when 'a' tends to infinity is zero.

Answer:
Initial amount: 934 g
After 80 years: 147 g
Step-by-step explanation:
\( A(t) = 934 (\dfrac{1}{2})^\frac{t}{30} \)
The initial amount occurs at t = 0.
\( A(0) = 934 (\dfrac{1}{2})^\frac{0}{30} \)
\( A(0) = 934 (\dfrac{1}{2})^0 \)
\( A(0) = 934 \times 1 \)
\( A(0) = 934 \)
After 80 years, t = 80.
\( A(80) = 934 (\dfrac{1}{2})^\frac{80}{30} \)
\( A(80) = 934 (\dfrac{1}{2})^\frac{8}{3} \)
\( A(80) = 934 (0.15749) \)

You have a credit card that has a balance of $3589.90 and a credit limit of $5000. How much is the balance over the acceptable debt ratio percentage?
Answers
The balance over the acceptable debt ratio is $1089.90.
What is debt ratio percentage?A debt ratio calculates a company's leverage by comparing its total debt to its total assets.
Although this ratio varies greatly between industries, capital-intensive enterprises typically have significantly larger debt ratios than other types of businesses.
Divide total debt by total assets to find a company's debt ratio.
A debt ratio of less than 100% signifies a corporation has more assets than debt, and a debt ratio of larger than 1.0 or 100% means the opposite.
According to some sources, the debt ratio is calculated by dividing all obligations by all assets.
Given that, credit card balance = $3,589.90
credit limit = $5,000
Debt Ratio percentage = 50% = 0.50
The balance over is given as
balance = Current Balance - (Credit Limit × 0.50 )
balance = 3589.90 - (5000 × 0.5)
balance = 3589.9 - 2500
balance = 1089.9
Hence, the balance over the acceptable debt ratio is $1089.90.

Answers
The monthly income of the first person is $600.
Given that, the average monthly income of three persons is RS 3,600.
The income of the first is 1/5 of the combined income of the other two.
Here, Let income of the first be A, let income of the second be B and let Income of the third be C.
A+B+C=3600 -----(i)
Income for the first person = 1/5(B+C) -----(ii)
Substitute equation (ii) in equation (i), we get
(B+C)/5 +B+C =3600
B+C+5B+5C=3600×5
6B+6C=18000
6(B+C)=18000
B+C=3000 ------(iii)
Substitute (iii) in equation (i), we get
A=$600
Therefore, the monthly income of the first person is $600.

No, there are x values which map to more than 1 y-value.
Given that Matthew examines the relation as shown in the below.

We need to check whether the relation is a function or not,
So, we know that,
A relation can map inputs to multiple outputs. It is a function when it maps each input to exactly one output. The set of all functions is a subset of the set of all relations.
If any x values are repeated, and the corresponding y values are different, then we have a relation and not a function.
