Answer:
(c) 65
Step-by-step explanation:
(f ⁰ g)(x) = 3(x² + 4) + 5
(f ⁰ g)(4) = 3(4² + 4) + 5 = 3*20 + 5 = 65
Solve the equation:
3e^(2x + 1) = 12
e^(2x + 1) = 12/3
e^(2x + 1) = 4
2x + 1 = ln(4)
2x + 1 = ln(2^2)
2x + 1 = 2 ln(2)
2x = 2 ln(2) - 1
x = [ 2 ln(2) - 1 ] / 2 <----- this is the answer.
________
Checking:
2x + 1 = 2 ln(2)
2x + 1 = ln(4)
e^(2x + 1) = e^[ ln(4) ]
e^(2x + 1) = 4
3e^(2x + 1) = 3 * 4
3e^(2x + 1) = 12 (checked)
I hope this helps. :-)
Answer: 2.50 dollars
Explanation:
Locate 5 on the x axis, which corresponds to buying 5 kgs of apples.
Draw a vertical line through 5 on the x axis until you reach the blue line. Mark this as point P.
From point P, draw a horizontal line until you reach the y axis. You should arrive at y = 2.5
This tells us that buying x = 5 kgs of apples will cost a total of y = 2.50 dollars.
Answer:
5%
Step-by-step explanation:
The first 20 single digit first numbers are 2,3,5 and 7. Thus they are four.
So next we calculate the percentage:
⇒ <u>4</u> × 100% = <u>1</u> × 100% = 5%
