The equation of the line that is perpendicular to y = -2x + 1​ will be y = (1/2)x + 1.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given line,

y = -2x + 1​

The slope(m) intercept form of a line is given as,

y = mx + c

By comparing,

Slope m = -2

The product of the slopes of the two perpendicular lines is -1.

Slope of perpendicular line (m') x -2 = -1

m' = 1/2

Put m' = 1/2 and (4,3) into y = m'x + C.

3 = (1/2)4 + C

C = 1

Thus, line will be y = (1/2)x + 1

Hence "y = (1/2)x + 1 will be the equation for the line that is perpendicular to y = -2x + 1.".

The inequality that describes Mr. Clarke's problem is x < 450/3.

This means that the cost of each camera must be less than $450/3, or $150.  This inequality means that Mr. Clarke can spend up to $450 on the cameras, but the amount he spends on each camera must be less than $450 divided by 3, or $150. To calculate this, we take the total budget of $450 and divide it by the number of cameras, which is 3. To solve this, we can use the formula x < 450/3. We can calculate the maximum amount Mr. Clarke can spend on each camera by multiplying 450 by 1/3, resulting in $150. Therefore, Mr. Clarke can spend a maximum of $150 on each camera in order to stay within his budget of $450.

Answer:

Step-by-step explanation:

Losing 15 % means 85% remains

  so multiply each year's value by .85 to find the current value

       after 'n'  years it will be  24300 * .85^n

when will it be 5600 ?

    5600 = 24300 * .85^n

     5600/24300  = .85^n  

             now you need to take the log of both sides and solve for 'n'  years

  log ( 5600/24300) / log(.85) = n = 9.031 = ~~ 9 years

The rocket will reach its maximum height after 7.438 seconds.

An equation shows the relationship between numbers and variables in an expression.

Let y represent the height of the rocket x seconds after its launch.

Given that:

y = -16x² + 238x + 81

The height of the rocket is maximum when the rate of change is zero. Hence:

The rocket reaches it maximum at dy/dx = 0

dy/dx = -32x + 238

-32x + 238 = 0

32x = 238

x = 7.438

The rocket height would be maximum at 7.438 seconds.

Answer: To find the midpoint of a line segment, you can average the x-coordinates of the endpoints and average the y-coordinates of the endpoints.

The x-coordinates of the endpoints are -1 and -9, so the average of the x-coordinates is (-1 + (-9))/2 = -5

The y-coordinates of the endpoints are 3 and -7, so the average of the y-coordinates is (3 + (-7))/2 = -2

So the midpoint of the segment with endpoints (-1, 3) and (-9, -7) is (-5, -2)

Step-by-step explanation:

The probability for the first digit of a random number of a data set to be greater than 7 is 0.097.

Here we are given a probability distribution table regarding Benford's law where all the probabilities about the occurrence of the first digit of a data set are given. As we can see that digit 1 has the highest probability with number 9, the least.

Here we need to find the probability that a randomly selected number, has a first digit greater than 7.

Here we don't have to think about Benford's law since the data already has given us the required distribution.

Hence P(D > 7) = P(D = 8) + P(D = 9)

= 0.051 + 0.046

= 0.097

Hence the probability for the first digit to be greater than 7 is 0.097.

The volume of the figure is has been determined to be 597.632 cubic centimeters.

The volume of a figure is the amount of substance that it can conveniently contain considering its dimensions. Each figure has a given formula to determine its volume.

Considering the figure in the question, divide it into two parts.

So that,

i. volume of the first part = length x width x height

                                      = 16.25 x 5.8 x 4.6

                                      = 433.55

The volume of the first part is 433.55 cubic cm.

ii. volume of the second part = length x width x height

                                            = (16.25 - 10.1) x 5.8 x 4.6

                                            = 6.15 x 5.8 x 4.6

                                            = 164.082

volume of the second part is 164.082

iii. Total volume of the figure = 433.55 + 164.082

                                           = 597.632 cubic centimeters

The total volume has been determined to be 597.632 cubic centimeters.

The value of cosec B if A and B are complementary is 15/7

Two angles are called complementary when their measures add to 90 degrees. Since A+B = 90°, then A and B are complementary. Examples of complementary angles are 45 and 45, 30 and 60, 20 and 70 e.t.c

If sec A is 15/7

sec A= 1/cos A

therefore cos A = 7/15

if cos A = 7/15 , then from law of complementary angles

cos A = sin (90-A)

and 90-A = B

therefore cos A = sinB

if cos A = 7/15, then;

sin B = 7/15

then sinB = 1/cosec B

cosec B = 15/7

therefore the value of cosec B = 15/7

Answer:

y = 4x + 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept, where it crosses the y- axis )

calculate m using the slope formula

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

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (- 2, - 4) ← 2 points on the line

m = [tex]\frac{-4-0}{-2-(-1)}[/tex] = [tex]\frac{-4}{-2+1}[/tex] = [tex]\frac{-4}{-1}[/tex] = 4

1. The ratio of the surface area to volume of the cube = 3/ 5

2. The ratio of the surface area to volume of the cuboid = 113/ 62

Surface area and volume of a figure.

The surface area of a given figure is the area of the total external boundary of the figure. While the volume of a figure is the quantity of substance that can fill up the figure.

To solve the question, we have;

1. The surface area of a cube = 6a

where: a = length x length

              = 10 * 10

            a = 100 square centimeters

So that;

surface area of the cube = 6*100

                               = 600 sq cm

ii. Volume of a cube = l^3

                        = 10^3

volume of the cube = 1000 cubic centimeters

iii. The ratio of its surface area to volume = 600/ 1000

                                        = 6/ 10 = 3/ 5

2. The surface area of a cuboid = 2a + 2b + 2c

                = 2(a + b + c)

where a = b = c = length * width

a = length x width

  = 4*2

a = 8 sq. m

b = length x width

  = 6.2 x 4

b = 24.8 sq. m

c = length x width

      6.2 x 2

c = 12.4 sq. m

Surface area of the cuboid = 2(8 + 24.8 + 12.4)

                      = 90.4 sq. m

ii. volume of a cuboid = length x width x height

                             = 6.2 x 4 x 2

                             = 49.6 cubic meters

iii. The ratio of surface area to volume of the cuboid = 90.4/ 49.6

                                                 = 113/ 62

Benito's gross pay for the week will be $757.07.

What are work and time?

In aptitude, work and time are related concepts that are used to calculate the rate of work being done.

Benito is to be paid time and a half for every hour over 40 that he works, so for a 49-hour work week, he will be paid for 49 - 40 = 9 hours of overtime.

His regular pay for the first 40 hours is $14.15 per hour * 40 hours = $566.

His overtime pay is $14.15 per hour * 1.5 = $21.23 per hour

His overtime pay for 9 hours is $21.23 per hour * 9 hours = $191.07

his gross pay for the week will be $566 + $191.07 = $757.07.

Hence, Benito's gross pay for the week will be $757.07.

The smallest possible integer value that 'a' could take is 6.

Perimeter is the total length of a shape's boundary.

Perimeter of equilateral triangle = 3a, where a is the side length

Perimeter of a square = 4b, where b is the side length

Let P₁ be the perimeter of equilateral triangle and P₂ be the perimeter of square.

Here,

Length of side of equilateral triangle = 4a + 2

P₁ = 3 (4a + 2)

Length of side of square = 2a + 7

P₂= 4 (2a + 7)

Given P₁ > P₂

3 (4a + 2) > 4 (2a + 7)

By distributive property,

12a + 6 > 8a + 28

12a - 8a > 28 - 6

4a > 22

a > 22/4

a > 5.5

Hence 6 is the smallest number which is an integer that 'a' could take.

The results generated in the map phase are combined in the _reduce_ phase.

In maps, the "reduced phase" refers to a technique used to remove the phase ambiguity present in interferometric synthetic aperture radar (InSAR) data. InSAR uses radar to measure the distance between a satellite or aircraft and the ground and can be used to create detailed maps of changes in the surface of the earth over time.

However, because InSAR data is collected using radar waves, which are sensitive to the phase of the signal, the data can be affected by phase ambiguities. The reduced phase technique is used to remove these ambiguities and create more accurate maps.
