To two decimal places, find the value of k that will make the function f(x) continuous everywhere. f of x equals the quantity 3x
Fiesta28 [93]

Given function is

f(x)=\left\{\begin{matrix}3x+k & x\leq -4 \\ kx^2-5 & x> -4\end{matrix}\right.

now we need to find the value of k such that function f(x) continuous everywhere.

We know that any function f(x) is continuous at point x=a if left hand limit and right hand limits at the point x=a are equal.

So we just need to find both left and right hand limits then set equal to each other to find the value of k

To find the left hand limit (LHD) we plug x=-4 into 3x+k

so LHD= 3(-4)+k

To find the Right hand limit (RHD) we plug x=-4 into

kx^2-5

so RHD= k(-4)^2-5

Now set both equal

k(-4)^2-5=3(-4)+k

16k-5=-12+k

16k-k=-12+5

15k=-7

k=-\frac{7}{15}

k=-0.47

<u>Hence final answer is -0.47.</u>

given data

He bought a video game system for $299

=0.0733*397

=29.1001

total cost = 29.1001+397

=$426

vagabundo [1.1K]

Answer:

260

Step-by-step explanation:

Number of hours in one year = 365 x 24 x 60 = 525600

(365 days, 24 hours per day, 60 minutes per hour)

One prize is won every 2018 minutes so in 525600 minutes

525600 / 2018 = 260 prizes will be won  (The answer is 260.46, which rounds to 260)
