Find k so that the following function is continuous:<br> f(x)={kx8x2if0≤x&lt;5if5≤x.
tankabanditka [31]

Check the one-sided limits:

\displaystyle \lim_{x\to5^-}f(x) = \lim_{x\to5}kx = 5k

\displaystyle \lim_{x\to5^+}f(x) = \lim_{x\to5}8x^2 = 200

If <em>f(x)</em> is to be continuous at <em>x</em> = 5, then these two limits should have the same value, which means

5<em>k</em> = 200

<em>k</em> = 200/5

<em>k</em> = 40

A firm offers routine physical examinations as part of a health service program for its employees. The exams showed that 8% of t
Alexxandr [17]

Answer: A. 0.20

Step-by-step explanation:

Let A be the event of employees needed corrective shoes and B be the event that they needed major dental work .

We are given that : P(A)=0.08\ ;\ P(B)=0.15\ ;\ P(A\cap B)=0.03

We know that P(A\cup B)=P(A)+P(B)-P(A\cap B)

Then,   P(A\cup B)=0.08+0.15-0.03= 0.20

Hence, the probability that an employee selected at random will need either corrective shoes or major dental work : P(A\cup B)= 0.20

hence, the correct option is (A).

Find the value of x. Then the measure of each angle
Shtirlitz [24]
The interior angles of a triangle must add to 180 degrees.

110+5x+2x=180
110+7x=180
7x=70
x=10

Then plug in the x value into each angle expression
5(10)=50 degrees
2(10)=20 degrees
