Answer:

h = V3B

Step-by-step explanation:

V = 1/3B · h

Divide volume by 1/3 B to get h by itself

V/1/3B = V3B

What is the value of the leading coefficient a, if the polynomial function P(x) = a(x + b)2(x − c) has a multiplicity of 2 at th

kirill115 [55]

If the polynomial function $P(x) = a(x + b)^2(x-c)$ has a multiplicity of 2 at the point (−1, 0) then the factor (x-(-1))=(x+1) twice enters the polynomial representation. So, you have known one part of the left side of the polynomial function that is $P(x) = a(x + 1)^2(x-c)$ .

If polynomial function passes through the point (7,0), then $0 = a(7+ 1)^2(7-c)$ and since $a\neq 0$ you have that c=7.

At last, if polynomial function passes through the point (0,-14), then $-14 = a(0+ 1)^2(0-7)$ and $-14=-7a$ , so a=2.
Answer: a=2.

31x-4+120 =180 How would I solve ? Any tips ?

KIM [24]

Answer:

x=64/31

Step-by-step explanation:

31x-4+120=180

31x+116=180

subtract 116 from both sides

Simplify

Divide both sides of the equation by the same term
