Answer:
y= 407.54654 ft
Step-by-step explanation:
This is an exponential decay functions
y = ab^x where a is the initial value and b is ( 1 - rate of decay)
a = 520
b = 1- 3%
y = 520 ( 1- .3) ^x
y = 520 ( .97) ^x
We want x to be 8 weeks
y = 520 ( .97) ^8
y= 407.54654 ft
Answer:
The answer is D: 37%
Ignore this answer its wrong, I think. Yeah you're gonna need someone else to figure this out. How do you delete answers on here?
Answer: 2.04
Step-by-step explanation: Hundreth is second from the decimal place on the right so you would remove the 7 since that is the thousandth.
You round up since th e next number 7, is a number you round up and not down
The sum is 4x³ + 3x² + 2x – 6.
Solution:
The correct question is given below.
(4x³ – 2x² + 3x – 1) + (5x² – x – 5). What is the sum?
<u>To find the sum of the polynomial:</u>
Sum of (4x³ – 2x² + 3x – 1) and (5x² – x – 5)
= (4x³ – 2x² + 3x – 1) + (5x² – x – 5)
Remove the parentheses.
= 4x³ – 2x² + 3x – 1 + 5x² – x – 5
Group like terms together.
= 4x³ – 2x² + 5x² + 3x – x – 1 – 5
Add the similar elements. i.e the element with same power.
= 4x³ + 3x² + 2x – 1 – 5
Subtract the constant terms.
= 4x³ + 3x² + 2x – 6
The sum is 4x³ + 3x² + 2x – 6.
Answer:
B. (-3, 0) and (-6,0)
Step-by-step explanation:
x intercept when y = 0
so x^2 + 9x + 18 = 0
Factor
(x + 6)(x + 3) = 0
x+6 = 0; x = -6
x+3 = 0; x = -3
Answer
B. (-3, 0) and (-6,0)
