Answer:

D)

Step-by-step explanation:

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have the following points through which the line passes:

[tex](x_ {1}, y_ {1}) :( 0, -7)\\(x_ {2}, y_ {2}) :( 5,12)[/tex]

Thus, the slope of the line is:

[tex]m = \frac {y- {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {12 - (- 7)} {5-0} = \frac {12 + 7 } {5} = \frac {19} {5}[/tex]

By definition, if two lines are parallel then their slopes are equal. Thus, a parallel line will be of the form:

[tex]y = \frac {19} {5}x + b[/tex]

Answer:

[tex]y = \frac {19} {5}x + b[/tex]

Answer:402.03

Step-by-step explanation:

Increasing by 5% is just multiplying by 1.05 then you repeat step for x amount of years

For this case we have the following quadratic equation:

[tex]p = -5x ^ 2 + 70x-165[/tex]

To find the roots, we equal 0.

[tex]-5x ^ 2 + 70x-165 = 0[/tex]

Where:

[tex]a = -5\\b = 70\\c = -165[/tex]

The solution will be given by:

[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}[/tex]

Substituting we have:

[tex]x = \frac {-70 \pm \sqrt {70 ^ 2-4 (-5) (- 165)}} {2 (-5)}\\x = \frac {-70 \pm \sqrt {4900-3300}} {- 10}\\x = \frac {-70 \pm \sqrt {1600}} {- 10}\\x = \frac {-70 \pm40} {- 10}\\x = - (-7\pm4)[/tex]

We have two roots:

[tex]x_ {1} = 7-4 = 3\\x_ {2} = 7 + 4 = 11[/tex]

Answer:

[tex]x_ {1} = 3\\x_ {2} = 11[/tex]

a. She pays $100 for 5 sheets

b. 25+15x dollars for x sheets

c. 8 sheets

Step-by-step explanation:

Given

Sitting cost = $25

Per sheet picture cost = $15

Let p be the number of sheets of pictures

Then the cost can be written as a function of p

[tex]c(p) = 25+15p[/tex]

Now,

a. How much does she pay for 5 sheets of pictures?!

Putting p = 5 in the function

[tex]c(5) = 25 + 15(5)\\= 25+75\\=100[/tex]

She will pay $100 for 5 sheets of pictures

b. How much does she pay for "x" sheets?

Putting x in place of p

[tex]c(x) = 25+15x[/tex]

c. How many sheets can she buy for $145?

We know the cost now, we have to find p so,

[tex]145 = 25+15p\\145-25 = 25+15p-25\\120 = 15p[/tex]

Dividing both sides by 15

[tex]\frac{15p}{15} = \frac{120}{15}\\p = 8[/tex]

Hence,

She can buy 8 sheets for $145

Answer:

g is a geometric sequence.

g(1) = 6

g(n) = g(n-1)*2

Step-by-step explanation:

A geometric sequence is one in which each next term is found by multiplying the previous term by a constant number.

In our case the rabbit population doubles each month, therefore we are multiplying the population of the previous month by 2 to get the population of the next month. Thus g(n) is a geometric sequence.

The sequence described is a geometric sequence with a ratio of doubling each month. The recursive formula for the sequence is g(1) = 6 and g(n) = 2*g(n-1).

The sequence described is a geometric sequence. In a geometric sequence, each term after the first is found by multiplying the previous term by a fixed, non-zero number called the ratio. In this case, that ratio is 2 because the rabbit population doubles every month.

When providing the recursive formula for the function g(n), the first term, g(1), would be 6, as that is the number of rabbits Fenyang started with. For any other term in the sequence, g(n), it would be twice the previous term, g(n-1). So, the complete recursive formula for the sequence would be:

The elevator can carry the adults with average mass of 80 kg.

Step-by-step explanation:

Given

Capacity to weight that can be hold by elevator = 2500 pounds

Average mass of one adult = 80 kg

Average mass of 10 adults = 80*10 = 800kg

We need to have the weights in same unit in order to determine whether the elevator can carry the adults or not.

We will convert the weight of 10 adults into pounds.

1 kg = 2.205 pounds

800 kg = 800*2.205 = 1764 pounds

Therefore,

1764 pounds < 2500 pounds

The elevator can carry the adults with average mass of 80 kg.

By converting the average mass from kilograms to pounds and multiplying by the number of adults, the total weight is calculated to be 1763.696 pounds, which is under the elevator's capacity of 2500 pounds, so the elevator can carry them safely.

The student is asking whether an elevator would be able to carry 10 adults with an average mass of 80 kg each without exceeding its maximum weight capacity of 2500 pounds. To answer this, we will first convert 80 kg to pounds and then multiply by the number of adults to find the total weight. After that, we can compare the total weight with the maximum capacity of the elevator.

First, let's convert the average mass of one adult from kilograms to pounds. Since 1 kg is equal to approximately 2.20462 pounds, we can calculate like this:

80 kg * 2.20462 lbs/kg = 176.3696 lbs per adult

Now, multiplying this by 10 adults:

176.3696 lbs/adult * 10 adults = 1763.696 lbs for 10 adults

When comparing this total weight of 1763.696 pounds to the elevator's maximum capacity of 2500 pounds, we see that the weight of 10 adults is less than the elevator's capacity.

Therefore, the elevator can safely carry 10 adults with an average mass of 80 kg each.

Answer:

A repeating or recurring decimal is decimal representation of a number whose digits are periodic (repeating its values at regular intervals) and the infinitely repeated portion is not zero. It can be shown that a number is rational if and only if its decimal representation is repeating or terminating (i.e. all except finitely many digits are zero). For example, the decimal representation of

1

/

3

becomes periodic just after the decimal point, repeating the single digit "3" forever, i.e. 0.333.... A more complicated example is

3227

/

555

, whose decimal becomes periodic at the second digit following the decimal point and then repeats the sequence "144" forever, i.e. 5.8144144144.... At present, there is no single universally accepted notation or phrasing for repeating decimals.

The infinitely repeated digit sequence is called the repetend or reptend. If the repetend is a zero, this decimal representation is called a terminating decimal rather than a repeating decimal, since the zeros can be omitted and the decimal terminates before these zeros.[1] Every terminating decimal representation can be written as a decimal fraction, a fraction whose divisor is a power of 10 (e.g. 1.585 =

1585

/

1000

); it may also be written as a ratio of the form

k

/

2n5m

(e.g. 1.585 =

317

/

2352

). However, every number with a terminating decimal representation also trivially has a second, alternative representation as a repeating decimal whose repetend is the digit 9. This is obtained by decreasing the final (rightmost) non-zero digit by one and appending a repetend of 9. 1.000... = 0.999... and 1.585000... = 1.584999... are two examples of this. (This type of repeating decimal can be obtained by long division if one uses a modified form of the usual division algorithm.[2])

Product of slope will be -1.

Step-by-step explanation:

We know that slope of the line describes its orientation , where tangent of the angle made by the line with the x axis will be the slope of the line .

Since here , We are given that line A and B are perpendicular to each other ,

If one line makes the angle a with x axis then other will make -(90-a) ,

So product of slope of the given lines will be , tan(a).tan-(90-a) = -1.

Now , sum of slopes can't be zero as they are not equal in magnitude

Has the form  y = kx :  

y = -0.05x

y =50x

Can be put in the form of y = kx:

y/7 = x

y/x = 6.5

other:

y = 1/5x - 1/5

2x + 1/2 = y

The equation y=kx is a form of a linear equation where there is a direct proportionality between the variables 'y' and 'x'. This equation reflects a direct variation scenario, where 'y' increases or decreases as 'x' does.

The question pertains to the understanding and categorization of linear equations, which are frequently used in Mathematics and Physics. You mention the equation y=kx, where 'k' is a number. It's a simplified version of the standard linear equation, y = mx + b, where 'm' is the slope (rate of change) and 'b' is the y-intercept (the value of 'y' when 'x' is zero). When 'b' is zero, we have the equation y=mx or in your context, y=kx, a direct proportionality.

For instance, if we see the equation y = 6x, it fits the category of y=kx where the 'k' value is 6. Such equations show a direct variation 'y' with 'x', meaning when 'x' increases or decreases, 'y' will also increase or decrease respectively.

Other forms of equations such as quadratic relationships or inverse relationships occur when the variables have a different kind of interaction, such as being squared or inversely proportional to each other.

Answer:

The answer is d

Step-by-step explanation:

Answer:

  BC = 10.89, ∠A = 39.59°, ∠B = 95.80°, ∠C = 44.61°

  BC = 27.34, ∠A = 140.41°, ∠B = 23.35°, ∠C = 16.24°

Step-by-step explanation:

Using the area formula to find angle A, we get ...

  Area = (1/2)bc·sin(A)

  65 = (1/2)(12)(17)sin(A)

  sin(A) = 65/102 . . . . divide by the coefficient of the sine term

  A = arcsin(65/102) = 39.59°   or   180°-39.59° = 140.41°

Then from the law of cosines*, ...

  BC² = AB² +AC² -2·AB·AC·cos(A) = 12² +17² ±2·12·17·cos(39.59°)

  BC² = 433 ± 314.426

  BC = √118.574   or   √747.426

  BC = 10.89 or 27.34

___

For A = 39.59° and BC = 10.89, the remaining angles are ...

  sin(C)/AB = sin(A)/BC

  C = arcsin(12·(65/102)/10.89) = arcsin(.7023) = 44.61°

  B = 180° -39.59° -44.61° = 95.80°

__

For A = 140.41° and BC = 27.34, the remaining angles are ...

  sin(C) = AB·sin(A)/BC = 12(65/102)/27.34

  C = arcsin(0.2797) = 16.24°

  B = 180° -140.41° -16.24° = 23.35°

__

In summary, the solutions are ...

  BC = 10.89, ∠A = 39.59°, ∠B = 95.80°, ∠C = 44.61°

  BC = 27.34, ∠A = 140.41°, ∠B = 23.35°, ∠C = 16.24°

_____

* For a given value of 0 < (x=sin(α)) < 1, there are two possible positive angles: α = arcsin(x) and 180°-α. In the Law of Cosines formula, these different angles result in cos(α) and cos(180°-α) = -cos(α).

_____

The solution process is the same for the remaining sides and angles, once you recognize that the initial value of sin(A)=65/102 can have two different angles as its solution.
