a line is perpendicular to y=-2x+5 and intersects the point (-4,2). what is the equation of this perpendicular line?

Answers

Answer:

y = 1/2x + 4

Step-by-step explanation:

If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.

So solve for b: using y = mx + b

2 = 1/2(-4) + b

2 = -2 + b

4 = b

Put it all together

y = 1/2x + 4

A line that passes through the points whose coordinates are (1,1) and (5,7)

is dilated by scale factor of 3 and centered at the origin. The image of the line


a) is perpendicular to the original line

b) is parallel to the original line

c) passes through the origin

d) is the same line

Answers

Answer:

B

Step-by-step explanation:

The image that the line will produce would be:

b). is parallel to the original line.

Given that,

Coordinates = [tex](1,1) and (5,7)[/tex]

Scale factor [tex]= 3[/tex]

As we know,

Slope [tex]= \frac{y_{2} - y_{1} }{{x_{2} - x_{1}} }[/tex]

where;

[tex]y_{2} = 7[/tex]

[tex]y_{1} = 1[/tex]

[tex]x_{2} = 5[/tex]

[tex]x_{1} = 1[/tex]

By putting these values,

Slope [tex]= (7 - 1)/(5-1)[/tex]

[tex]= 6/4[/tex]

[tex]=[/tex] [tex]1.5[/tex]

∵The image of the line would be ║ to the original line.

Thus, option b is the correct answer.

Write the equation for an exponential function that triples ever year, x, when the original amount is 4.

Answers

Answer:

y = 4(3)^x

Step-by-step explanation:

Here, we want to write the exponential equation

From the question, we have the equation tripling in x value every year and the original amount is 4

The exponential equation is of the form;

y = a(b)^n

In this case;

a = 4 , b = 3 and n = x

So we have the equation as;

y = 4(3)^x

Answer:

BC ≈ 5.44 m

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] , that is

cos27° = [tex]\frac{BC}{6.1}[/tex] ( multiply both sides by 6.1 )

6.1 × cos27° = BC , then

BC ≈ 5.44 m ( to 3 significant figures )

Write an equation of the line that passes through (1,2) and is parallel to the line y = -5x+4

Answers

Answer:

y =-5x + 7

Step-by-step explanation:

y = -5x + 4

Slope = -5

Parallel lines have same slope

Slope of the parallel line to this line = -5

y -y1 =m(x - x1)

y - 2 = -5(x - 1)

y -2 = -5x + 5

Answers

Answer:

263 / 280

Step-by-step explanation:

Given that :

Number of tickets bought = required outcome = 17

Total number of raffle = total possible outcomes = 280

Probability = required outcome / Total possible outcomes

P(winning) = 17 / 280

P(not winning) = 1 - 17/ 280

in order to get an A Mark needs to get at least 90% of the 650 points possible in the class. How many points must he earn of the 150-point final if he averaged 92 points on each of the five 100-point test

Answers

Answer:

at least 125 points on the final

Step-by-step explanation:

90% of 650 = 585

He needs at  least 585 points to get at least 90%

Since he averaged 92 on the first 5 tests, he already has 5(92) = 460 pts

That means he needs to get at least 585 - 460 = 125 pts on the final exam

A company sells widgets. The amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation. Using this equation, find out
the maximum amount of profit the company can make, to the nearest dollar.
y= -2x^2 + 105x – 859

Answers

Answer:

519

Step-by-step explanation:

or 519.125

The maximum amount of profit the company can make, to the nearest dollar should be considered as the $519.

Calculation of the maximum amount of profit

Since the amount of profit made expressed as [tex]y=-2x^2+105x-859[/tex]

Now

At maximum profit, dy/dx = 0

So,

dy/dx = -4x + 105

0 = -4x + 105

4x = 105

x = 105/4

x = 26.25

Now

[tex]y=-2x^2+105x-859\\\\y=-2(26.25)^2+105(26.25)-859[/tex]

y = - 1,378.125+2,756.25-859

y = 519.125

Hence the maximum amount of profit the company can make is $519.
