Find The Equation Of The Line Which Passes Through (-2,-2) And (2,-4).
Answer 2

Equation of a line is given by

m (x - x¹) = (y - y¹)

where m is the gradient [tex]m \: = ( {y}^{2} - {y}^{1} ) \: \div ({x}^{2} - {x}^{1} )[/tex]

where (x¹ , y¹ ) and (x² , y²)

(-2,-2 ) and (2 , -4)

m = ( -4 - (-1) ) ÷ ( 2 - (-2) )

m = ( -4 + 1 ) ÷ ( 2 + 2 )

m = ( -3 ) ÷ ( 4 )[tex]m \: = - \frac{3}{4} [/tex]

but equation of a line is given by

m (x - ) = ( y - )

[tex] - \frac{3}{4} (x - ( - 2)) \: = \: (y \: - ( - 2))[/tex][tex] - \frac{3}{4} (x + 2) \: = \: (y \: + \: 2)[/tex]expanding the bracket

[tex] - \frac{3}{4} x \: - \: \frac{3}{2} \: = y \: + \: 2[/tex][tex]y \: = \: - \frac{3}{4} x \: - \: \frac{3}{2} \: - \: 2 \\ \\ y \: = - \frac{3}{4} x \: - \: \frac{7}{2} \\ \\ {y} \: = \frac{ - 3x \: - \: 14}{4} [/tex][tex]multiply \: by \: 4[/tex][tex]4 \: \times \: y \: = 4 \: \times \: \frac{ - 3x \: - 14}{4} [/tex][tex]4y \: = \: - 3x \: - \: 14[/tex]Equation of the line is

4y = -3x - 14

Which of the following functions would give the population Plt) as a function

is growing at an annual rate of 4%?
(1) P(t)=2500(0.96)
(3) P(t)=2,500(1.04)
(2) P(t)=(1.04) +2,500
(4) P(t)= 1.04t +2,500

Answers

Answer:

[tex]P(t)=2500(1.04)^t[/tex]

Step-by-step explanation:

None of your proposed answers has an exponent t.

Here's the logic behind the answer:

Year 0: pop. = 2500

Year 1:  pop. = 2500(1.04)  That is 104% of the previous year's pop.

Year 2: pop. = 2500(1.04)(1.04) = 2500(1.04)^2

Year 3: pop. = 2500(1.04)^2 x (1.04) = 2500(1.04)^3

See the pattern?  The exponent matches the year number.

Jordan sold his used lawn tractor and accessories for $980. If he received nine times as much money for the lawn tractor as he did for the accessories, find how much money he received for the lawn tractor

Answers

Answer: [tex]\$882[/tex]

Step-by-step explanation:

Given

Jordan sold lawn tractor and accessories for [tex]\$980[/tex]

he receives 9 times more money for a tractor than for accessories

Suppose, he receives x amount for accessories

So, for tractor it is [tex]9x[/tex]

total amount is

[tex]\Rightarrow 9x+x=980\\\Rightarrow 10x=980\\\Rightarrow x=\$98[/tex]

He receives [tex]9x=\$882[/tex] for tractor

Marcus is rolling a number cube with sides labelled 1 to 6 .find the probability it will show 10​

Answers

Answer:

Probability of getting number 10  = 0

Step-by-step explanation:

Given;

Total sides of cube die = 6

Find:

Probability of getting number 10

Computation:

Total number of cube = 1, 2, 3, 4, 5, 6

Favorable outcome for 10 = 0

Probability of an event = Favorable outcome / Number of outcomes

Probability of getting number 10 = 0 / 6

Answers

Answer:

7350 J

Step-by-step explanation:

The gravitational potential energy of a body can be found by using the formula

GPE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

We have

GPE = 2.5 × 9.8 × 300

Answers

Answer: The answer is 280 ft.

Step-by-step explanation:

divide the green area into a triangle and a rectangle so it's easier to calculate. Then find the area of the rectangle by multiplying 14 times 16. That should get you 224. Then, find the area of the tringle by multiplying 14 times 18, times 1/2. That will get you 56. If you add 56 to 224, that gets you 280.

8-50. What is the area of a regular decagon if the length of each side is 20 units? Show all your work.

Answers

Answer:

3077.68

Step-by-step explanation:

the Area of the regular decagon is 3077.68

The area of the decagon with side length of 20 units is -

A = 1000√(5 + 2√5) square units.

What is Area?

Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write area -

V = ∫∫F(x, y) dx dy

Given is a regular decagon with length of each side is 20 units

The area of the regular decagon is -

A = (5/2)a²√(5 + 2√5)

We have {a} = 20. So, we can write that -

A = (5/2)(20)²√(5 + 2√5)

A = (5/2) x 400 x √(5 + 2√5)

A = 5 x 200 x √(5 + 2√5)

A = 1000√(5 + 2√5)

Therefore, the area of the decagon with side length of 20 units is -

A = 1000√(5 + 2√5) square units.

Answers

y = 3x - 9

slope: 3
intercept: -9

Answer:

y = 3x - 9

Step-by-step explanation:

Let's start by finding the slope of the line:

The formula for slope is [tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex].

Plug in the numbers and solve:

[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]

[tex]m = \frac{-3 - (-6)}{2 - 1}[/tex]

[tex]m = \frac{3}{1}[/tex]

[tex]m = 3[/tex]

The slope of the line is 3.

The slope intercept form of a line is y = mx + b, where m is the slope and b is the y coordinate of the y-intercept.

Plugging in the number we got for the slope, the equation becomes:

y = 3x + b

Let's solve for b by plugging in an ordered pair for y and x:

y = 3x + b

-3 = 3(2) + b

-3 = 6 + b

b = -9

The y-coordinate of the line is (0, -9).

Now, plugging in the number into our equation, we get:

y = 3x + (-9)

y = 3x - 9

And that's the equation of the line!

Which statement identifies how to show that j(x) = 11.6ex and k(x) = In (StartFraction x Over 11.6 EndFraction) are inverse functions?

Answers

Answer:

The answer is "It must be shown that both [tex]j(k(x))\ and \ k(j(x))=x[/tex]"

Step-by-step explanation:

Given:

[tex]j(x) = 11.6 e^{x} \\\\k(x) =\ln\frac{x}{11.6}[/tex]

To show that both are equal functions, and  show that both[tex]j(k(x))\ and\ k(j(x)) =x,[/tex]

For [tex]j(k(x));[/tex]  

[tex]j(k(x)) = j[(\ln \frac{x}{11.6})]\\\\j[(\ln (\frac{x}{11.6})] = 11.6e^{\ln (\frac{x}{11.6})}\\\\j[(\ln \frac{x}{11.6})] = 11.6(\frac{x}{11.6})\\\\[/tex](The natural logarithm is canceled by exponential function)  

[tex]j[(\ln \frac{x}{11.6})] = 11.6 \times\frac{x}{11.6}\\\\j[(\ln \frac{x}{11.6})] = x\\\\j[k(x)] = x\\\\for\ \ k[j(x)]:\\\\k[j(x)] = k[11.6e^x]\\\\k[11.6e^x] = \ln (\frac{11.6e^x}{11.6})\\\\k[11.6e^x] = \ln(e^x)[/tex]

Its natural logarithm leaving x will nullify expanding universe.

[tex]k[11.6e^x] = x\\\\k[j(x)] = x[/tex]

In the question, it is seen that[tex]j[k(x)] = k[j(x)] = x[/tex], shows that the functions [tex]j(x) = 11.6 e^{x} \ and \ k(x) = \ln \frac{x}{11.6}[/tex] is inverse functions.
