Answer:

Step-by-step explanation:

If the population of wolves is increasing, then the function will represent exponential growth. So the number inside the parentheses must be greater than 1. That narrows it down to the last 2. But it's exponential growth, so it includes an exponent. D doesn't have an exponent, so you're left with C :)

B, it's the most logical; 6% as a decimal is (.06 and that's what B has)

Deena drove 585 miles in 9 hours. Kristen drove 605 miles in 11 hours. Who drove at a faster rate? How do you know?

Rashid [163]

Divide miles driven by time and compare them.

Deena: 585 /9 = 65 miles per hour

Kristen: 605 /11 = 55 miles per hour

Deena drove at a faster rate because 65 is greater than 55.

Help please!! I’ve gotten this wrong twice and if I get it wrong again then I’m going to fail.

Answer: Choice A (yes it is a function; one range value exists for each domain value)

Put another way, each x corresponds to exactly one output only. We do not have any repeat x values. Any input you specify, there is only one output. If for example we had the two points (3,5) and (3,7) then the input x = 3 leads to multiple outputs y = 5 and y = 7 at the same time. This example is a non-function because of this. In this case, we don't have such repeated x values so that is why we have a function.

Try graphing out the four points given. You'll notice you cannot draw a vertical line through more than one point. Therefore, this graph passes the vertical line test. The vertical line test is to see if it's possible to draw a vertical line through more than one point on the graph. If so, then the relation fails to be a function.

X^2-8x+16=5 what are the solutions?

svp [43]

Hey!

The first step to solving this equation would be to subtract 5 from both sides of the equation.

Original Equation :
$x^{2}$ - 8x + 16 = 5

New Equation {Added Subtract 5 to Both Sides} :
$x^{2}$ - 8x + 16 - 5 = 5 - 5

Now we solve our new equation.

Old Equation :
$x^{2}$ - 8x + 16 - 5 = 5 - 5

Solution {Old Equation Solved} :
$x^{2}$ - 8x + 11 = 0

The next step would be to solve with the quadratic formula.

Quadratic Equation ( 1 ) :
$x = \frac{-(-8) + \sqrt{(-8)^{2} -4 * 1 * 11 } }{2*1}$

Quadratic Equation ( 1 ) {Solved} :
4 + $\sqrt{5}$

Quadratic Equation ( 2 ) :
$x = \frac{-(-8) - \sqrt{(-8)^{2}-4 *1*11 } }{2*1}$

Quadratic Equation ( 2 ) {Solved} :
4 - $\sqrt{5}$

So, our final solutions for the equation $x^{2}$ - 8x + 16 = 5 are...

x = 4 + $\sqrt{5}$

and 

x = 4 - $\sqrt{5}$

Hope this helps!
