f(x) = (x + 5)(x - 1)
using the ' factor theorem '
given x = a is the root of a polynomial then (x - a ) is a factor
here roots are x = - 5 and x = 1 hence factors are (x + 5) and (x - 1)
the polynomial is the product of the factors
f(x) = (x + 5)(x - 1)
Answer:
The function rule be 100 × x
The independent variables i.e. (2, 3, and 4) are considered to be the domain
The dependent variable (200,300,400) are considered to be the range
Step-by-step explanation:
The computation is shown below:
As we know that
1 m = 100 cm
So
2 m = 200 cm
3 m = 300 cm
4 m = 400 cm
The function rule be 100 × x
The independent variables i.e. (2, 3, and 4) are considered to be the domain
The dependent variable (200,300,400) are considered to be the range
I am 100% positive it is 0 and 5
<span>THE AREA OF THE ROOM IS :A=4*2.4=9.6 m^2
THICKNESS t=0.30 m
DIFFERENCE IN TEMPERATURE dT=18-6=12
q=kAdT/dx=kA*dT/t
q=1.3(9.6)(12)/0.30=4992 W=499.2 J/s
In 1 hour or 3600 sec
P=q*T=(499.2 J/s)(3600 s)=1797120 J=1.8 MJ

- Each person stacks 20 in one minute.
- 5 people can stack 100 in 5 minutes.
If so, how long would 250 take them ?
-- The same 5 people can stack 250 in (250/100)= 2.5 minutes.
