Answer:

C. k is greater than zero.

Step-by-step explanation:

We know that graph is obtained from the function of the form f(x) = a\cdot (x+k)^{1/n} + c. According to the graph and if x + k = 0, we find that:

x = -k (1)

x < 0 (2)

By (1) and (2):

-k < 0

k > 0

Hence, correct answer is C.

A car's speedometer has a percent error of 5%. The speedometer currently shows that the car is traveling at a speed of 60 mph.
Minchanka [31]

Answer:

The actual speed of the car is either 57 mph or 63 mph

Step-by-step explanation:

Given as :

The measured speed o the car = 60 mph

The percentage error in speedometer = 5 %

Let The actual speed of car = x mph

Now, percentage error = \dfrac{\textrm actual value - \textrm measured value}{\textrm measured value} × 100

So, \frac{5}{100} = \frac{x - 60}{60}

or,  \frac{5}{100} × 60 = x - 60

Or, 3 = x - 60

∴  x = 63 mph

Hence The actual speed of the car is either 57 mph or 63 mph . Answer

Answer:

a=2

Step-by-step explanation:

8a +9=3a +19

Subtract 9 from both sides

-9=      -9

8a=3a +10

Subtract -3a from both sides

5a=10

5a=10

5a divided by both sides

5/5

10/5=2

a=2
