ANSWER:
An exponential growth function has constant doubling time.
Step-by-step explanation:
EXPLANATION:
The formula for calculating exponential growth is
A=A'e^kt
here:
A=amount after growth
A'=initial value
e=2.718
k=continuous growth rate
t=time passed
Given : ABCF is a Rectangle
⇒ AB = CF
Given : AB = 6 cm
⇒ CF = 6 cm
Perimeter of a Rectangle is given by : 2(Length + Width)
Given : Perimeter of the Rectangle = 20 cm
⇒ 2(6 + BC) = 20
⇒ 6 + BC = 10
⇒ BC = 4
Given : BD = 9
But, We can See that : BD = BC + CD
⇒ CD + 4 = 9
⇒ CD = 5
We know that :
✿ 
Where : a and b are Lengths of Parallel Sides and Height is Length between those Parallel Sides
In the Given Trapezium :
The Parallel Sides are CD and EF and Height is CF
Given : EF = 3 cm
Answer:
y = (x - 5)(4x + 1)
Step-by-step explanation:
The given function y = 4x^2 -19x - 5
Here we have to find the AC method.
Identify the value of A, B and C
A = 4 , B = -19 and C = -5
AC = 4*-5 = -20
Now find the facotr -20 such that when we add those two factors, we have to get the value of B. That is B = -19
Factors are -20 and 1
1 * -20 = -20
1 + (-20) = -19
y = 4x^2 -19x - 5
This can be written using the factors
y = 4x^2 - 20x + 1x - 5
Now let's factor by group the first two terms, then second two terms.
y = 4x (x - 5) + 1(x - 5)
y = (x - 5)(4x + 1)
That's the answer.
Hope this will helpful.
Thank you.
Answer:
The last one which you was on is correct.
<span>Best Answer: 1) Q is positive therefore the process is endothermic. .769kj+-.810kj=-.041kj
2) Heat is released meaning it is exothermic. -66.9kj+45=-21.9kj
3) 7.29kj. Endothermic.</span>
