Answer:
The equation of circle A with radius AC is , or in other words option d.
Step-by-step explanation:
If the radius of this circle is AC, then we can determine the distance between points A ( - 1, 4 ) and C ( - 5,1 ) to come to the length of the radius -
Distance between A and C =
=
= = = 5 units - Which is also the length of the radius of the circle.
So if the radius is given to be 5 in length, knowing that the general equation for a circle is ( where ( h, k ) is the center and r is the radius ) if the radius is 5, , and solution must be option b / option d.
Now if the radius is AC, the center point must be point A ( circle A ). Therefore point ( - 1, 4 ) is the center, and the equation of the circle must be the following -
= - and hence our solution is option d
3 less than a number is an expression.
First we find the slope of the given line by using slope intercept form.
Converting the equation into slope intercept form
Divide both side by 5 we get
On comparing with
We get slope
as the slope of line is negative therefore the line will either "b" or "d"
As line "b" pass from (0,2)
On putting it in given equation we get
Which is not equL to RHS of the line
Therefore b is not the given line
Now putting point (0,-2)
We get
Satisfy the equation and line "d" pass from it
There the give equationis of line "d"
Answer:
a. 72 = 2 x 2 x 2 x 3 x 3
b. 252 = 2 x 2 x 3 x 3 x 7
c. 625 = 5 x 5 x 5 x 5
Step-by-step explanation:
Answer:
1. 1:2
2. x=12
3. $25:$20
4. 15 cats
5. 16 t
6. p=4
7. $15/6 = 2.50
8. 10/5=2 8/2=4 x=4
8b. 8:10=4:5
9. 270/3=90=1 person 90 x 10=$900
you need $900 to bring 10 people on the fishing trip.
