Answer: 54

Step-by-step explanation:

Since the triangles are similar, the sides form s equalivent proportion. The hypotunse of the bigger triangle and the smaller triangles correspond with each other and the base of the smaller and larger triangle correspond so we use this proportion: hypo. of big triangle/ base of larger triangle= hypo of smaller triangle/ base of smaller triangle.

Let substitue: 52.5/x= 5/4: ( I  Reduce 15/12 into 5/4).Cross multiply:    210=5x: Divide by 5 both sides. x=42. Then add the 42 and and the 12 to find the whole distance which is 54.

Answer:

Step-by-step explanation:

Given:

The points are (5,40) and (0,10).

To find:

The equation for the trend line using the given points.

Solution:

If a line passes through two points, then the equation of the line is:

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Two points are (5,40) and (0,10). So, the equation of trend line is

[tex]y-40=\dfrac{10-40}{0-5}(x-5)[/tex]

[tex]y-40=\dfrac{-30}{-5}(x-5)[/tex]

[tex]y-40=6(x-5)[/tex]

[tex]y-40=6x-30[/tex]

Adding 40 on both sides, we get

[tex]y=6x-30+40[/tex]

[tex]y=6x+10[/tex]

Therefore, the equation of trend line is [tex]y=6x+10[/tex].

Expanded Form Will Be: 36000

Given:

The graph of a function.

To find:

The range of the function.

Solution:

Range is the set of y-values or output values.

From the given graph it is clear that,

[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]

[tex]f(x)\to \infty\text{ as }x\to \infty[/tex]

And the value function can be any real number. So,

Range = [tex]-\infty<y<\infty[/tex]

Range = [tex](-\infty, \infty)[/tex]

Range = y is all real numbers.​

Therefore, the correct option is D.

Answer:

D. y is all real numbers.​

Step-by-step explanation:

Range is the set of y-values or output values.

From the given graph it is clear that,

And the value function can be any real number. So,

Range =

Range =

Range = y is all real numbers.​

Therefore, the correct option is D.

Answer:

1.630

Step-by-step explanation:

Answer with explanation:

To prove: [tex]a^2-a[/tex] is divisible by 2 for any whole value of a.

Consider [tex]a^2-a=a(a-1) \ \ \ \ [\text{ Taking 'a' out as common }][/tex]

Here, a and (a-1) are two consecutive numbers such that,

either of them must be an odd number and an even number.

i.e. a(a-1)= Product of even and an odd number = Even number  [Trivial statement]

⇒ a(a-1) is divisible by 2 [Every even number is divisible by 2.]

⇒  [tex]a^2-a[/tex] is divisible by 2 for any whole value of a.

Hence proved.

r=9

Step-by-step explanation:

Answer:

r = 12.1

Step-by-step explanation:

r - 18.7 = -6.6

 + 18.7   + 18.7 ( add 18.7 to both sides)

r = -6.6 + 18.7

r = 12.1

Answer:

Step-by-step explanation:

a) Data and Calculations:

Estimated useful life of a computer = 5 years

Cost of a computer purchased = $2,400

Annual depreciation expense = $480 ($2,400/5)

This means that the business owner chooses to spread (expense) the cost of the computer over 5 years at a rate of $480.

After 3 years, the cost already expensed = $1,440 ($480 * 3)

The Remaining value of this computer after 3 years of use will be $960 ($2,400 - $1,440).

b) Depreciation is an accounting method for spreading (or expensing) the cost of a long-term asset over its useful life.
