|7m–56|, if m<8 write without using absolute value
Ilia_Sergeevich [38]

Answer:

56-7m

Step-by-step explanation:

l7m–56l m<8

so lets replace m with something smalller then 8, how about 7

so then it would be...

l 7 * 7 - 56 l=

l 49-56 l = l -7 l

but the absulute value of -7 is 7, so how does this help us? well lets see

56-49= 7  this proves that all we have to do is  switch the order giving us the solution 56-7m

hope this helped :)

OverLord2011 [107]

Answer:

At the 3rd day 160 students caught flu.

Step-by-step explanation:

Consider the provided model P = − t ² + 13t + 130 where 1 ≤ t ≤ 6

The total number of students is represents by P.

We need to find the day that 160 students had the flu.

Substitute the value of P=160 in above formula.

160 = -t^2 + 13t + 130

160+t^2 - 13t - 130=0

t^2 - 13t +30=0

t^2 - 10t-3t +30=0

t(t-10)-3(t-10)=0

(t-10)(t-3)=0

Hence the value of t=10 or t=3

But it is given that  1 ≤ t ≤ 6, Therefore select t=3

Hence, at the 3rd day 160 students caught flu.

Form a polynomial with zeros:−2 multiplicity 3; 1 multiplicity 2; 3 multiplicity 1;degree 6 You may leave your answer in factore
Darina [25.2K]

Answer:

f(x) = (x+2) (x+2)^3 (x-1) (x-6)

Step-by-step explanation:

The first zero, -2, corresponds to the factor x+2 of the polynomial.

Given that this zero, -2, has multiplicity 3, (x+2)^3 represent the first three factors of the polynomial.

The next factor stems from the zero 1:  (x-1).

The next 6 factors stem from the zero 6:  (x-6).

Writing the polynomial in factored form, we get:

f(x) = (x+2) (x+2)^3 (x-1) (x-6)
