Given that a<span> computer manufacturer built a new facility for assembling computers where they paid for construction and new equipment costs. This means that at the start of business by the company, the company has a negative profit.

Given that the company made combined profits of $10 million after 4 years, this means that the graph of the comany's profit against number of years will pass though point (4, 10 million)

Given that profits increased $7.5 million per year, this means that the slope of the graph of </span><span>the comany's profit against number of years is $7.5 million.

The equation of a line passing though point (x_1,y_1) with slope, m is given by
y-y_1=m(x-x_1)

Thus given that the line passes through point (4, 10 million) and has a slope of 7.5 million, the equation of the line is given by
y-10,000,000=7,500,000(x-4)=7,500,000x-30,000,000 \\  \\ y=7,500,000x-20,000,000

At the y-intercept, i.e. when x = 0: y = 7,500,000(0) - 20,000,000 = 0 - 20,000,000 = -20,000,000

Thus the y-intercept is negative 20 million.

At the x-intercept, i.e. when y = 0: 0 = 7,500,000x - 20,000,000
7,500,000x = 20,000,000
x = 20,000,000 / 7,500,000 ≈ 2.7

Thus the x-intercept is approximately 2.7

Therefore, </span>the correct graph of this function is <span>a graph of a line that has a y-intercept that is approximately negative $20 million and an x-intercept that is approximately 2.7 years.</span>

I need qestion number d) solution please help me​
natita [175]

Answer:

It is an identity, the proof is in the explanation

Step-by-step explanation:

csc(A)-cot(A)=tan(A/2)

I'm going to start with right hand side

tan(A/2)=(1-cos(a))/(sin(a))                half angle identity

tan(A/2)=1/sin(a)-cos(a)/sin(a)         separate fraction

tan(A/2)=csc(a)-cot(a)                     reciprocal and quotient identities

At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. T
elixir [45]

Answer:

\text{Exact area of the sidewalk}=40 \pi\text{ m}^2

\text{Approximate area of the sidewalk}=125.6\text{ m}^2

Step-by-step explanation:

We have been given that at a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. The inner edge of the sidewalk is a circle with a radius of 9 m.

To find the area of the side walk we will subtract the area of inner edge of the side walk of lion pen from the area of the outer edge of the lion pen.

\text{Area of circle}=\pi r^2, where r represents radius of the circle.

\text{Exact area of the sidewalk}=\pi*\text{(11 m)}^2-\pi*\text{(9 m)}^2

\text{Exact area of the sidewalk}=\pi*\text{121 m}^2-\pi*\text{81 m}^2

\text{Exact area of the sidewalk}=40 \pi\text{ m}^2

Therefore, the exact area of the side walk is 40 \pi\text{ m}^2

To find the approximate area of side walk let us substitute pi equals 3.14.

\text{Approximate area of the sidewalk}=40*3.14\text{ m}^2

\text{Approximate area of the sidewalk}=125.6\text{ m}^2

Therefore, the approximate area of the side walk is 125.6\text{ m}^2.

What is 5x + 3x equal to
Gekata [30.6K]
The answer is 8x.
You are combining like terms as 5 and 3 both have x so you are simply adding 5+3= 8
