Answer:

p(x) =  - 0.7(x - 3)^{2} (x + 2)

Step-by-step explanation:

We have that the polynomial, has a root of multiplicity 2 at x = 3 and a root of multiplicity 1 at x = -2.

This means the factored form of the polynomial will be.

p(x) = a(x - 3)^{2} (x + 2)

Also, it was given that, the y-intercept is y=-12.6.

This implies that:

- 12.6= a(0 - 3)^{2} (0 + 2)

- 12.6= a(- 3)^{2} (2)

- 12.6= 18a

Divide both sides by 18;

a =  \frac{ - 12.6}{18}

a= - 0.7

Therefore the polynomial is

p(x) =  - 0.7(x - 3)^{2} (x + 2)

Why is (-3,6] a better answer than (-3,6)
Pani-rosa [81]

(-3, 6) includes all numbers between -3 and 6 but it does not include -3 and 6.

when you put square parentheses you include the number on the edge

so if an anwser includes all numbers between -3 and 6 and the number 6 it's correct to write (-3,6]

  • <u> </u><u>Height</u><u> </u><u>of </u><u>the </u><u>house </u><u>is</u><u> </u><u>2</u><u>5</u><u>m</u>

\bold{\underline{ So, }}

\sf{ CE = 25m }

\sf{ AB = AD - CE }

\sf{ AB = 60 - 25  }

\sf{ AB = 35 m }

\bold{tan Φ =}{\bold{\frac{ AB}{BC}}}

\bold{tan Φ =}{\bold{\frac{ 35}{35}}}

\bold{ tan Φ = 1 }

\bold{ tan Φ = 45 °}

\sf{\red{Hence, \: The \:angle \:of \:depression\: is \:45°}}

The function h(t) = 210 – 15t models the altitude of a hot air balloon over time t, in minutes.
Liula [17]
H(10) is the altitude of a hot air balloon overtime after 10 minutes. In order to find h(10)'s value, you just have to substitute 10 as t in the equation. h(10) and h(t) represents the value of y in a linear equation. So pretty much: h(10)= 210 - 15(10). If calculated correctly, h(10)=60.
