Which function has a removable discontinuity at x = 7?
9514 1404 393
Answer:
(b) see below
Step-by-step explanation:
A removable discontinuity exists when the function is undefined at a point where the limit exists.
Choices A, C, D have no limit at x=7 (does not exist).
__
Choice B can be simplified to ...
f(x) = (x -3)(x -7)/(x -7)
f(x) = (x -3) . . . . . . . x ≠ 7 (domain restriction; undefined at x = 7)
The discontinuity in this function can be removed by defining the function to be f(x) = x-3 everywhere.

B

george has opened a new store and he is monitoring its success closely. He has found that this store’s revenue each month can be modeled by r(x)=x2+5x+14 where x represents the number of months since the store opens the doors and r(x) is measured in hundreds of dollars. He has also found that his expenses each month can be modeled by c(x)=x^2−4x+5 where x represents the number of months the store has been open and c(x) is measured in hundreds of dollars.
the new store will sell 900 items in its fifth month in business
the store will have a profit of $900 after its fifth month in business
the store will have a profit of $5400 after its fifth month in business
the new store will sell 5400 items in its fifth month in business
Answer:
Step-by-step explanation:
The correct answer is that the new store will have a profit of $5400 after its fifth month.
Profit is given by subtracting revenue minus cost:
(R-C)(x) = (x²+5x+14)-(x²-4x+5) = x²-x²+5x--4x+14-5 = 5x+4x+14-5=9x+9
Using 5 for x,
(R-C)(5) = 9(5) + 9 = 45+9 = 54
This is in hundreds of dollars, so it represents $5400.
Sam took his savings to the bank and deposited them in a Certificate of Deposit (CD) account. He was told that he would collect the full interest in 260 weeks. How many years would Sam have to wait to collect the full interest
Answer:
5
Step-by-step explanation:
260 weeks divided by however many weeks in a year which is 365÷7 which is 52.14 so it would be rounded to 52
260÷52⇒5
you look down at an object on the ground. If your eyes are
55 feet above the ground, and the angle of depression is 50º, how far is the object
from you?
i believe it’s 2,750 feet?
Answer:
We can think of this as a triangle rectangle.
We know that you eyes are 55ft above the ground, this can be one cathetus.
We also know that you see with an angle of depression of 50°, from this angle, our known cathetus would be the opposite cathetus.
Now we want to know how far is the object from you, this would be the hypotenuse of the triangle rectangle.
So we only know one angle and the opposite cathetus to this angle, then we can use the relation:
Sin(θ) = (opposite cathetus)/(hypotenuse)
Then if we use this equation, we will get:
Sin(50°) = 55ft/hypotenuse
hypotenuse = 55ft/sin(50°) = 71.8 ft
This means that the distance between you and the object is 71.8 ft.

Write the equation of a parabola in factored form if the x-intercepts are (3,0) and (-5,0) with a maximum point at ( -1,8)
Answer:
y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5)
Step-by-step explanation:
Given the x- intercepts are x = 3 and x = - 5 then the corresponding factors are
(x - 3) and (x + 5)
The equation is the the product of the factors, that is
y = a(x - 3)(x + 5) ← a is a multiplier
To find a substitute (- 1, 8) into the equation
8 = a(- 1 - 3)(- 1 + 5) = a(- 4)(4) = - 16a ( divide both sides by - 16 )
- [tex]\frac{1}{2}[/tex] = a
Then
y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5) ← in factored form

The bases of a cylinder have a diameter of 4 inches. The height of the cylinder is 6 inches. What is the total surface area of the cylinder?
Answer:
Step-by-step explanation:
area of base = π4² = 16π in²
lateral area = 2πrh = 2π·4·6 = 48π in²
surface area = 2×16π + 48π = 80π in² ≅ 251.3 in²
Answer: 100.54 in^2
Step-by-step explanation:
(the area of a circle*2) + (the circumference*the height) = the surface area of the circle
Area of a circle: Pi*r^2
Circumference: 2*Pi*r
