Alright, lets get started.
Jen picked three fourth in half an hour.
Half an hour means 30 minutes.
At the same rate, how many she can pick in 2 hours.
2 hours means minutes
Now,
In 30minutes, Jen can pick =
In 1 minute, Jen can pick =
In 120 minutes, Jen can pick =
Hence Jen can pick complete 3 in 2 hours of time.
So the answer is 3 : Answer
Hope it will help :)
<em><u>Solution:</u></em>
<em><u>The given exponential function is:</u></em>
<em><u>The exponential function is given as:</u></em>
Where,
y is the future value
a is the initial value
r is the growth rate
t is the number of years
<em><u>Compare both the functions,</u></em>
a = 1
Thus growth rate is:
<em><u></u></em>
<em><u>Evaluate the function when t = 5</u></em>
Substitute t = 5 in given
Thus the value is 18.9 when t = 5
Answer:
The roots of given quadratic equation lies from
Step-by-step explanation:
Given as :
The quadratic equation is x² - x -6 = 0
The quadratic equation is in form of ax² + bx +c = 0
Let x1 and x2 be the roots of equation
Sum of roots
So,
And products of roots is x1 × x2 =
So,
Or, x1 + x2 = 1 ......A
And x1 × x2 =
Or, x1 × x2 = - 6
Now, (x1 - x2)² = (x1 + x2)²+ 4×x1×x2
Or, (x1 - x2)² = (1)²+ 4×6
Or, (x1 - x2)² = 25
So , x1 - x2 = = 5 ......B
Now solve eq A and eq B
Or, (x1 + x2) + (x1 - x2) = 1 +5
Or, 2 x1 = 6
∴ x1 = 3 And x2 = - 2
Hence The roots of given quadratic equation lies from Answer
