Answer:
y = 18
Step-by-step explanation:
Since the triangles are similar, the corresponding sides are in proportion, that is
=
, substitute values
=
( cross- multiply )
14y = 252 ( divide both sides by 14 )
y = 18

Answer:
Step-by-step explanation:
Give the rate of change of sales revenue of a store modeled by the equation . The Total sales revenue function S(t) can be gotten by integrating the function given as shown;
a) The total sales for the first week after the campaign ends (t = 0 to t = 7) is expressed as shown;
Total sales = S(7) - S(0)
= 6,860 - 0
Total sales for the first week = $6,860
b) The total sales for the secondweek after the campaign ends (t = 7 to t = 14) is expressed as shown;
Total sales for the second week = S(14)-S(7)
Given S(7) = 6,860
To get S(14);
The total sales for the second week after campaign ends = 13,720 - 6,860
= $6,860
Answer:
y = - x²
Step-by-step explanation:
Since the vertex is at the origin and the focus at (0, - 4) then the parabola opens vertically down with equation
x² = 4py ( p is the distance from the vertex to the focus )
Here p = - 4 ( focus is below the vertex ), thus
x² = 4(- 4)y = - 16y ( divide both sides by - 16 )
y = - x²
