Answer:

at + vi = vf

Step-by-step explanation:

In order to solve for vf, we need to isolate said variable.

a = vf - vi/t (Given)

at = vf - vi (Multiply t on both sides)

at + vi = vf (Add vi on both sides)

Candace ate 3 over 4 cup of cereal. The box of cereal states that one serving of cereal is equal to 2 over 3 cup. Which fraction

choli [55]

Answer: Candace ate $\dfrac9{12}$ servings.

Step-by-step explanation:

Given: Candace ate $\dfrac34$ cup of cereal.

The box of cereal states that 1 serving of cereal = $\dfrac23$ cup.

i.e. 1 cup = $\dfrac32$ servings [Multiply $\dfrac32$ both sides]

⇒ $\dfrac{3}{4}$ cup = $\dfrac34\times\dfrac32$ servings

= $\dfrac9{12}$ servings [which is the number of servings she ate]

Hence, Candace ate $\dfrac9{12}$ servings.

The points J(-1,-9) and K(5,1) are endpoints of a diameter of circle S. Which equation represents circle S? A. (x − 2)2 + (y + 4

Andrew [12]

Answer:

the equation of the circle is

$(x-2)^2+(y+4)^2 = 34$

Step-by-step explanation:

Recall that the equation of a circle is given by $(x-h)^2+(y-k)^2 = r^2$ where r is the radius, and (h,k) is the center. Recall that given two points that are the endpoints of a diameter, the center of the circle is their correspondent midpoint. Also, recall that given points (a,b), (c,d) their midpoint is obtained by $(\frac{a+c}{2},\frac{b+d}{2})$

In this case we are given the endpoints (-1,-9), (5,1). So the center of the circle is the midpoint obtained by $(\frac{-1+5}{2},\frac{-9+1}{2}) = (2, -4)$ . Recall that the radius of a circle is the distance from the radius to any of the points of the circle. So, the radius is the distance between the center and the point (-1,-9). We will calculate r^2, by using the distance formula. REcall that the distance between points (a,b), (c,d) is given by
