Answer:
none of the above; $531.71
Step-by-step explanation:
Fill in the given numbers and do the arithmetic.
A = $360·e^(0.13·3) = $360·e^0.39 ≈ $360·1.1.47698
A ≈ $531.71
___
None of the offered choices is correct. Have your teacher show you how this problem is worked.
_____
Answer choice c) is approximately correct for an interest rate of 16%. The correct value would be $581.79.
The first thing to do is to set this equal to zero, then move the constant over to the other side of the equals sign so we only have the x terms to worry about.
. Now we're ready to complete the square. We take half the linear term, square it, and add it in to both sides. Our linear term is -6x. Half of 6 is 3, and 3 squared is 9, so we add 9 to both sides:
. Now we will do the math on the right to get 4, and on the left we will express the perfect square binomial we created while completing this process.
. Now we can move the constant back over by subtraction to get
. Now we can see that the vertex is (3, -4). Since this is a positive parabola, it opens upwards, like a cup, which means that the lowest part of the parabola, the vertex, is sitting at the bottom, or at a minimum value. So our answer is C
Answer:
Step-by-step explanation:
The unit rate would be how much she earns per hour.
Divide 24 by 2 1/2
24 / 2.5 = 9.60
The unit rate is $9.60 per hour
What is the square root of 74 to the nearest tenth is 8
