Determine the values of the constants b and c so that the function given below is differentiable. f(x)={2xbx2+cxx≤1x>1
To make the function differentiable, we need to make it continuous at x = 1 by ensuring that both sides of the function have the same value. The values of the constants b and c are b = 1 - c, where c is any real number.
Explanation:The function given is:
f(x)={2xbx2+cxx ≤ 1 x > 1
To determine the values of the constants b and c such that the function is differentiable, we need to make sure that the function is continuous at x = 1 and both sides of the function have the same derivative at x = 1.
To do this, we need to find the limits of the function as x approaches 1 from both the left and the right sides.
From the given function, we can see that when x ≤ 1, the function is a polynomial and is differentiable for any value of b and c.
However, when x > 1, the function is not differentiable unless we choose the values of b and c such that the function becomes continuous at x = 1.
To make the function continuous, we need to make sure that both sides of the function have the same value at x = 1.
Substituting x = 1 into the given function, we have 2b(1)(1) + c(1) = b + c = 1 (since the function should be continuous at x = 1).
Therefore, the values of the constants b and c that make the function differentiable are b = 1 - c, where c is any real number.

given that,
At the sandwich shop, there are four different types of meat and three different types of cheese.
If you select a sandwich without looking,
then we need to find the probability.
Solution
There are four different types of meat and three different types of cheese
Probability = number of required outcome / number of possible outcome
Total amount of meat = number of possible meat = 4
If you only have one favorite type of meat the probability 1/4
Hence, the correct answer is Option B.

The number 1.2795 represents

A camera manufacturer spends $2,100 each day for overhead expenses plus $9 per camera for labor and materials. The cameras sell for $14 each. a. How many cameras must the company sell in one day to equal its daily costs? b. If the manufacturer can increase production by 50 cameras per day, what would their daily profit be?
Here, first we need to find the number of cameras that can be sold, so that total costs are equal to total revenues.
Let the number of cameras that can be sold be "x".
Total revenue = $ 14x
Total costs will be = $ 2100 + $9x
So, the equation that will be formed ⇒
14 x = 2100 + 9x
5x = 2100
x = 420
Thus, in order to make total costs equal to total revenues, 420 cameras are required to be sold.
If instead of 420, 470 cameras are sold, the daily profit will be calculated as under -
Total revenue = $ 14 × 470 cameras = $ 6,580
Total costs = $ 2100 + ( $ 9 × 470 cameras) = $ 6,330
Daily profit = Total revenue - Total costs = $ 6,580 - $ 6,330 = $ 250

Answer: [tex]-7+(-10)+(-13)+(-16)+(-19)+(-22)=-87[/tex]
Step-by-step explanation:
Given finite sequence : -7, -10, -13, . . ., -22.
Difference between first and second term=[tex]-10-(-7)=-10+7=-3[/tex]
Difference between second and third term =[tex]-13-(-10)=-13+10=-3[/tex]

Jim picked a card from a standard deck. What is the probability that Jim picked a heart or an ace?
Answer:
The answer is actually 16/52.
Step-by-step explanation:
There are 13 hearts and 4 aces. However, one of the 4 aces is a heart, so there would only be 3 other aces.
13 hearts + 3 other aces = 16
There are 52 cards in a deck, so the probability would be 16/52.

a tennis ball machine serves a ball vertically into the air from a height of 2 feet, with an intial speed of 130 feet per second. What is the maximum height, in feet, the ball will attain? round to the nearest hundredth
Final answer:
Using the kinematic equation for vertical motion, the maximum height a tennis ball will reach when fired at an initial speed of 130 ft/s from a height of 2 feet is approximately 264.91 feet.
Explanation:
Calculating the Maximum Height of a Tennis Ball
The maximum height that a tennis ball will attain when fired vertically can be calculated using the kinematic equations that describe projectile motion. Given that the initial speed of the ball is 130 feet per second and it is launched from a height of 2 feet, we can use the equation for vertical motion:
v^2 = u^2 + 2gh
where v is the final velocity (0 ft/s at the highest point), u is the initial velocity (130 ft/s), g is the acceleration due to gravity (-32.2 ft/s^2, negative because it is directed downwards), and h is the height gained. Rearranging the formula to solve for h we get:
h = (v^2 - u^2) / (2g) = (0 - 130^2) / (2 * -32.2)
After calculating h, we add the initial launch height of 2 feet to find the maximum height above ground:
Maximum Height = h + 2 feet
By plugging in the values, we can find the maximum height to be:
Maximum Height = (0 - 16900) / (-64.4) + 2 ≈ 264.91 feet (rounded to the nearest hundredth).
Therefore, the maximum height attained by the tennis ball is approximately 264.91 feet.
