Answer:

a° = 41°

b° = 139°

Step-by-step explanation:

a° = ∠DB

a° = 41°  

b° + 41° = 180°

b° = 180° - 41°

b° = 139

y = 4/7x - 3

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.

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

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

Answer: 2/5

Step-by-step explanation:

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.

Answer:

9/8

Step-by-step explanation:

The solution of the expression '1/4 divided by 2/9' in a reduced fraction is 9/8.

Used the concept of division which states that,

The division method is used to distribute a group of things into equal parts. The division is just the opposite of multiplications.

Given that,

1/4 divided by 2/9.

Now, divide the numbers and find the reduced fraction as,

1/4 divided by 2/9

It can be written as,

[tex]\dfrac{1}{4} \div \dfrac{2}{9}[/tex]

[tex]\dfrac{1}{4} \times \dfrac{9}{2}[/tex]

[tex]\dfrac{9}{8}[/tex]

So, the solution is 9/8.
