What is the equation in standard form for the circle with center (0, 0) that goes through the point (-5, 12)?

Mathematics

Mumz [18]3 years ago

Start with the standard equation of a circle with center at (h,k) and radius r:

(x-h)^2 + (y-k)^2 = r^2. Substitute -5 for h and 12 for k:

(x-0)^2 + (y-0)^2 = r^2

Next, we substitute -5 for x and 12 for y, with the objective of determining the value of r^2:

(-5-0)^2 + (12-0)^2 = r^2. Then 25 + 144 = 169 = r^2, and r = 13.

Thus, the answer choice "x2 + y2 = 169" is the correct one.

Important: Please use " ^ " to denote exponentiation: x^2 + y^2 = 169.

What can be concluded from the pie chart?
QveST [7]

The information that can be concluded from the pie chart is in 2018, more than one-fourth of the revenue collected for state and local governments in Florida came from sales taxes.

A pie chart is a circular graph that is used to show information. The circle is divided into sectors used to represent a numerical proportion. A pie chart adds up to 100%.

The pie chart in this question shows the sources of state and local revenue for Florida in 2018. The circle is divided into seven sectors that represent the sources of revenues.

The following can be deduced from the pie chart:

  • Excise taxes represent 1.2% of 100% of the circle. This is the smallest source of revenue for the state of Florida. Corporate income taxes represent 2% of the circle. Income from excise tax was less than income from corporate income taxes.

  • The sector that represents property tax is 13.7% and the sector that represents sales tax is 26.1%. Sales tax was a greater source of revenue when compared with property tax.

  • The proportion of sales tax to total revenue is 26.1%. This is more than 25%(1/4) of total revenue.

The original price of a car is entered into spreadsheet cell A1 and the annual depreciation amount in cell B1.
Reil [10]

Answer:

A1 / B1 ;

(D1 - A1) / B1 ;

(A1 - E1*A1) / B1

Step-by-step explanation:

A1 = original price of car

B1 = annual Depreciation amount

Number of years it will take for the car to depreciate totally :

Using the straight line Depreciation relation :

y = mx + c

c = intercept = initial or original value of car

m = annual Depreciation amount

x = number of years

y = value after x years

For total Depreciation, final value, y = 0

0 = mx + c

mx = - c

x = - c / m

Hence, x = A1 / B1

B.)

D1 = car value

Length it will take for car to depreciate to value in D1 :

y = mx + c

y = D1; m = B1 ; c = A1

D1 = B1x + A1

B1x = D1 - A1

x = (D1 - A1) / B1

C.)

E1 = decrease percentage

Time it takes for car to decrease by percentage in E1

y = E1 * A1

E1 * A1 = B1x + A1

(A1 - E1*A1) = B1x

x = (A1 - E1*A1) / B1
