the equation formula of the circle is (x-h)^2 + (y-k)^2 = r^2
where (h,k) the point of the center of the circle
and (r) is the radius of the circle
so if the center of the circle = (-2,-4)
by subs. in the formula we get (x-(-2))^2 + (y-(-4))^2 = r^2
then the equation will be (x+2)^2 + (y+4)^2 = r^2
now we want to define the radius of the circle r
since point (3,8) lay on the circle so we can
then subs. in the equation to get the radius
(x+2)^2 +(y+4)^2 = r^2
(3+2)^2 +(8+4)^2 = r^2
25 + 144 = r^2
r^2 = 169
r= 13
the radius of the circle is 13
so by subs in the equation we get
(x+2)^2 + (y+4)^2 = 169
so it is the first answer in the choices

What is a Trigonometric equation?

A Trigonometric equation is an equation involving one or more trigonometric ratios of unknown angles.

How to solve?

2cos2x + cosx − 1 = 0

$-3+\cos \left(x\right)+4\cos ^2\left(x\right)=0$

$\cos \left(x\right)=(3)/(4),\:\cos \left(x\right)=-1$

And now,

$x=\pi +2\pi n$

Which is only $x=\pi$ .

Step-by-step explanation:

which of the following are reasonable answers for the product of two negatives and a positive? •20 •10 •-20 •-10

Answers

The product of two negatives and one positive will give you a negative number. Take the three numbers; -1, -1, and 1. There are two negatives and one positive.
-1 x -1 x 1 = 1 x 1 = 1 = positive number
So the possible answers are the positive numbers:

20 and 10

Hope this helps :)

The correct answers are:

20 and 10.

Explanation:

Multiplying two negatives results in a positive product. Multiplying this positive product by another positive number will result in a positive answer. This means the only possible answers from our choices are the two positive ones, 20 and 10.

Dad is 7 times as old as his son. 10 years later, he will be three times as old as his son.find their ages?

Answers

so dad is represented by x
son is represented by y

so x is (x=) 7 times his son (7y)

our first sentence is x=7y

10 years later (x+10, y+10) he will be 3 times as old as his son (x+10=3(y+10))
or 10+x=3(y+10)

so our sentences are
x=7y
and
x+10=3(y+10)
first we subsitute x=7y for x in the second equation
(7y)+10=3(y+10)
7y+10=3(y+10)
we distribute
7y+10=3y+30
subtract 3y from both sides
4y+10=30
subtract 10 from both sides
4y=20
divide both sides by 4
y=5

the son is currently 5 years old
x=7y
subsitute y=5 for y in equation
x=7(5)
x=35
the dad is currently 35 years old
in 10 years
dad is 45 and son is 15

dad=35
son=5

these are the answers
son = 5
dad= 35
