Which equation represents a circle with a center at (–3, –5) and a radius of 6 units?

Shalnov [3]

Answer:

Step-by-step explanation:

The general equation of the circle is:

(x-h)²+(y-k)²=r²

(h, k)=(-3,-5) are the coordinates of the center of the circle.

r=6 is the radius

The equation of the circle is:

(x+3)²+(y+5)² = 36

Kyle divided two numbers in scientific notation using the interactive calculator and found a solution of 3.5E4. If the numerator

Maru [420]

Answer:

a=2, b=5

Step-by-step explanation:

Let

n -----> the denominator

we have

$3.5*10^4=\frac{7*10^9}{n}$

Solve for n

That means -----> isolate the variable n

Multiply by n both sides

$3.5*10^4(n)=7*10^9$

Divide by 3.5*10^4 both sides

$n=\frac{7*10^9}{3.5*10^4}=(\frac{7}{3.5})(\frac{10^9}{10^4})=2*10^5$

therefore

a=2, b=5

Referring to the Fig. in Question #40, find the unknown length Y.

icang [17]

Answer:

tan30°=7/x

$\frac{1}{ \sqrt{3} } = \frac{7}{x } \\ x = 7 \sqrt{3}$

cos30°=x/y

$\frac{ \sqrt{3} }{2} = \frac{7 \sqrt{3} }{y} \\ \\ 7 \sqrt{3} \times 2 = \sqrt{3} \times y \\ \frac{7 \sqrt{3 } \times 2}{ \sqrt{3} } = y \\7 \times 2 = y \\ 14 = y$

tell me if it's wrong.
