What’s the equation of the circle with the center of five, -4 that passes through -3, two

Mathematics
1 answer:
ratelena [41]3 years ago
4 0

Answer:

(x-5)^2 + (y+4)^2 = 100

Step-by-step explanation:

First you need to know the equation of a circle which is,

(x – h)^2 + (y – k)^2 = r^2

(h,k) is the center point and r is the radius.

To find the radius use the distance formula which is

d=\sqrt(x2-x1)^2 + (y2-y1)^2 when you substitute you will get

\sqrt(5+3)^2 + (-4-2)^2 which simplifies to 10. That is the radius.

Then you will substitute that and the center point back into the equation to get the answer.

A cashier at a store has five dollars in $20 bills if there are six times as many five dollar bills as $20 bills and the total m
erastovalidia [21]
X = $20 bills
6x = $5 bills

x(20) + 6x(5) = 1450
20x + 30x = 1450
50x = 1450
x = 29
6(29)= 174

Write an equation in standard form that is parallel to the line y = 2x - 1 that passes through the point (1, 2). 2x - y = 0 O x
timofeeve [1]

Answer:

2x - y = 0

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x - 1 ← is in slope- intercept form

with slope m = 2

Parallel lines have equal slopes, thus

y = 2x + c ← is the partial equation

To find c substitute (1, 2) into the partial equation

2 = 2 + c ⇒ c = 2 - 2 = 0

y = 2x ← equation in slope- intercept form

Subtract y from both sides

0 = 2x - y , that is

2x - y = 0 ← equation in standard form

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB = 8
Delicious77 [7]

Answer:

x = 32

Step-by-step explanation:

∠BCA = ∠DBA (90 - ∠DBC)

∠A = ∠A

ΔABD similar to ΔACB

AC/AB = AB/AD

x / 8 = 8 / 2

x = 32
