Triangle AOC intersects a circle with center O. side AO is 10 inches and the diameter of the circle is 12 inches. What is the le

zvonat [6]

Answer:

$AC=8inches$

Step-by-step explanation:

It is given that triangle AOC intersects a circle with center O, side AO is 10 inches and the diameter of the circle is 12 inches, thus

OC is the radius of the circle and is equal to $\frac{D}{2}=\frac{12}{2}=6 inches$ .

Now, From ΔAOC, using the Pythagoras theorem, we get

$(OA)^{2}=(OC)^{2}+(AC)^{2}$

⇒ $(10)^{2}=(6)^2+(AC)^2$

⇒ $100=36+(AC)^2$

⇒ $64=(AC)^2$

⇒ $AC=8inches$

What is the product of -3a and -6a

Bezzdna [24]

Answer:

18a^2

Step-by-step explanation:

Multiply the numbers together. Multiply the variables together.

(-3a)(-6a) = (-3) * (-6) * a * a = 18a^2

-3 times -6 = 18 since negative times negative is positive, and 3 * 6 = 18.

Also a * a = a^2.

Answer: 18a^2

A sum of money invested at the compound interest payable yearly has interest in

jeka94

Answer:

49% and 30% respectively

Step-by-step explanation:

Step one:

Given data

Principal = Rs. 4,200

Final Amount= Rs. 9282 respectively

time = 2 years and

time = 4 years

Required

The rate of interest for 2 and 4 years

Step two:

the compound interest formula is

A= P(1+r)^t

for 2 years

Substitute

$9282= 4200(1+r)^2\\\\9282/4200= (1+r)^2$

$1+r= \sqrt{\frac{9282}{ 4200} }\\\\1+r= \sqrt{2.21} \\\\1+r= 1.49\\\\r=1.49-1\\\\r= 0.49\\\\$

the rate is 49%

For 4 years we have

$9282= 4200(1+r)^4\\\\9282/4200= (1+r)^4$

$1+r= \sqrt[4]{\frac{9282}{4500} } \\\\1+r=\sqrt[4]{2.21} \\\\1+r= 1.30\\\\r=1.30-1\\\\r= 0.30\\\\$

the rate is 30%

Help me find the answer

elixir [45]

Answer:

y = - $\frac{1}{4}$ x - 3

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 )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (4, - 4) ← 2 points on the line

m = $\frac{-4+3}{4-0}$ = - $\frac{1}{4}$

Note the line crosses the y- axis at (0, - 3) ⇒ c = - 3

y = - $\frac{1}{4}$ x - 3 ← equation of line
