Answer:

f'(x) = 7

Step-by-step explanation:

This is a basic derivative problem. The first derivative of f(x) would multiply the 7 by the power of x (which is one) and get rid of the 8. So, all you have left is 7 times 1 and your answer would be 7.

Answer:

x=-8/7 or -1.1428

Step-by-step explanation:

The roots (zeros) are the x

values where the graph intersects the x-axis. To find the roots (zeros), replace f(x) with 0 and solve for x

The correlation between height and weight for a certain breed of plant is found to be 0.75. What percentage of the variability i
WINSTONCH [101]

Answer:

The percentage of the variability in plant weight is NOT explained by height is  

      p = 43.75%

Step-by-step explanation:

From the question we are told that

      The correlation between height and weight is  r = 0.75

Generally the R-Squared  between height and weight is mathematically represented as

        R - square  =  r^2

substituting values

         R - square  =  0.75^2

         R - square  =  0.563

This R-Squared tells us the percentage of plant weight is accounted by height

and from the calculation we see that it is  56.3%

Now the percentage of plant weight that is not accounted by height is

          p =  100 - 56.3

          p = 43.75%

The Absolute value bars act as the P in PEMDAZ (The P = Parenthesis but it really just means any containing symbols ( (), {}, [], || ) so you distrubute -2 into the bars resulting in the numbers becoming negative then you follow the steps down :)

In Chicago a taxi ride cost $3.25 plus $1.80 for each mile traveled. Debbie has budgeted $19 for a taxi ride (excluding tip) how
frutty [35]
Write an equation based on the problem
3.25 is fixed cost, and 1.80 is variable cost, so the equation will be
3.25 + 1.80x = 19.00
x represents the distance she can travel

Solve the equation
3.25 + 1.80x = 19.00
1.80x = 19.00 - 3.25
1.80x = 15.75
x = 15.75/1.80
x = 8.75

She can travel 8.75 miles for the taxi ride
