Mark and Zoe are hiking a trail. Mark starts before Zoe. The expression 2t + 100 represents how far, in meters, Mark has hiked t
olasank [31]

Answer: No

Step-by-step explanation:

The distance hiked of Mark is represented by 2*t + 100

and the distance hiked of Zoe is represented by 2*t

here, you can see that the slope of both equations is equal, this means that in the same lapse of time, Zoe and Mark displace the same amount, but because Mark started earlier, he has a y-intercept bigger than zero, so for every value of t, the distance that Mark hiked will be higher than the one of Zoe.

We can represent this by:

2*t + 100 > 2*t

100 > 0

So the distance hiked by Mark is always bigger than the one of Zoe

The graph of y =(x-3)^2 is shifted left 4 units and down 2 units. What is the axis of
Naddik [55]

Answer:

x = -1

Step-by-step explanation:

The axis of symmetry of the graph y=(x-3)^2 is  x=3 but,

If shift the graph 4 units to the left it would mean the new value of x would be -1 as shown here:

x=3-4\\x=-1

-4 because it shifted 4 units to the left so the axis of symmetry of the transformed graph would be x = -1 and since it shifted 2 units down the y-coordinate of the turning point would be -2 so the turning point of the original graph is (3 , 0) and the turning point of the transformed graph is

(-1 , -2) I attached an image so you can visualize clearly

Find the principle needed to have a balance of $1000 after 10 years invested at 3.25% interest compounded continuously
xeze [42]
You will need to use this formula
Principal = Total / [e^(rate*years)]
(where "e" is the mathematical constant 2.718281828459)
Principal = 1,000 / [e^.0325*10]
Principal = 1,000 /  <span> <span> <span> 1.384030646 </span> </span> </span> <span><span> </span> </span>
Principal = 722.53
