Answer:
The solution sets are 1, 5 and 7
Step-by-step explanation:
Given the polynomial function,
f(x) = x³-13x²+47x-35
If 1 is a zero function of f(x), according to factor theorem, the linear equation x-1 is a factor of the polynomial.
To get the other solution set, we will have to divide the polynomial function by x-1 and factorize the quotient function.
Factorising the resulting quotient function.
Q(x) = x²-12x+35 = 0
= x²-5x-7x+35 = 0
= x(x-5)-7(x-5) = 0
(x-5)(x-7) = 0
x-5 = 0 and x-7 = 0
x = 5 and 7
Answer:
168 ft
Step-by-step explanation:
1. Calculate the total length of the curtains
42 curtains × (48 in/1 curtain) = 2016 in
2. Convert to inches to feet
1 in = ¹/₁₂ ft
2016 in × (¹/₁₂ ft/1 in) = (2016/12) ft = 168 ft
Ariceli will need 168 ft of fabric.
Answer:
125 dogs and cats
Step-by-step explanation:
35 puppies make up 28% of the total dog and cat population
so 28% of the total population is 35
let x = the total population
0.28x = 35
x = 35 / 0.28
x = 125 <=== total dogs and cats
A soma de 3 numeros igual a 8470 seria:
X + Y + Z = 8470
Como é dito que o 1º é 4319 e o 2º 1843, entao
X + Y + Z = 8470
4319 + 1843 + Z = 8470
Z = 8470 - 4319 - 1843
<h3>Z = 2308</h3>
To get the answer you must see how many times 7 can go in 114
