A third-degree polynomial function f has real zeros -2, ½, and 3, and its leading coefficient negative. Write an equation for f.
Rom4ik [11]
F(x) = k(x+2)(2x-1)(x-3), where k is some constant
= k(2x^3-3x^2-11x+6)
= k(-2x^3+3x^2+11x-6)

k defines some vertical stretch, so there are an infinitely many solutions for f(x).

Mom can't go until she finishes the housework is dependent on events

independent events. [Dependent events]

<h3>What is probability?</h3>

The probability exists in the analysis of the possibilities of happening of a result, which exists acquired by the ratio between favorable cases and possible cases.

Conditional probability directs to the possibility that some outcome happens given that another possibility contains also occurred.

Justine only goes when her friend goes [Conditional probability]

Independent events exist as those possibilities whose occurrence exists not dependent on any other event.

Mom going to PROM and Justine going to PROM are separate events. [Independent events]

Dependent events exist that depend upon what occurred before.

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 2 units,
Serggg [28]

Answer:

2

Step-by-step explanation:

he value of K would be 2 because the function f(x) is the equation of a line. K is represented as the y-intercept. When a line is shifted down 2 units, the y-intercept also gets shifted down 2 units. In f(x) the y-intercept is zero. So the difference would be 2 units

⦁The areas of two similar triangles ABC and DEF are 100 cm2 and 144 cm2. If EF = 15 cmthen find the length of side BC.
ch4aika [34]

we know that


area larger triangle (DEF)=[scale factor]²*area smaller triangle (ABC)

solve for scale factor

scale factor=√[area larger triangle/area smaller triangle]

scale factor=√[144/100]------> scale factor=1.2


therefore

measure EF=scale factor *measure BC

solve for measure BC

measure BC=measure EF/scale factor-------> 15/1.2------> 12.5 cm


the answer is

measure BC is 12.5 cm
