What is the slope of a line parallel to the line whose equation is 4x+5y= -35. Fully simplify your answer

Answer:

(x = 0,y = 0),(x = 1, y = 5),(x= 2, y =10)

Step-by-step explanation:

the rule is to multiply x by 5.

when x = 0, y =5(0) = 0

when x = 1, y =5(1) = 5

when x = 2, y =5(2) = 10

A table can be completed by plugging x-values into an equation or by graphing.

Plug in x-values

First, plug 0 into the equation to find the first y-value.

Next, plug in 1 for x

Finally, plug in 2

Additionally, each of these y-values increases by 5. So, once we found the first y-value, 0, we can just add 5 to find the next y-values.

Graphing

Also, you can use a graph to find the missing values. The y-intercept is 0 and the slope is 5. Using this information you can graph the equation. Then, find the x-values on the graph and match these values to y-values.

The angles of the cyclic quadrilateral are

In a cyclic quadrilateral the opposite angles are supplementary hence we have that

x - 4 + x + 8 = 180 degrees

gathering like terms

2x = 180 - 8 + 4

2x = 176

isolating x

x = 88 degrees

angles on each side

x- 4 = 88 - 4 = 84

x + 8 = 88 + 8 = 96

2x - 78 = 2(88) - 78 = 98

sum of the angles of a cyclic quadrilateral is 360

the fourth angle = 360 - 84 - 96 - 98

the fourth angle = 80 degrees

The error of closure (EC) is a measure of the accuracy of a closed loop leveling survey.

To calculate the error of closure, we need to subtract the sum of the foresight values from the sum of the backsight values. In this case, the sum of the backsight values is (7.85 ft + 3.55 ft + 4.51 ft + 5.01 ft) = 20.92 ft, and the sum of the foresight values is (5.57 ft + 3.87 ft + 5.15 ft + 6.11 ft) = 20.70 ft.

The error of closure (EC) can be obtained by subtracting the sum of the foresight values from the sum of the backsight values: EC = (sum of backsight values) - (sum of foresight values) = 20.92 ft - 20.70 ft = 0.22 ft.

Therefore, the correct answer is c) 0.22 ft, which represents the error of closure in this leveling survey.

Answer: zero

Step-by-step explanation:

slope is "rise over run", and there is no ("0") "rise" as the y-value is not increasing; as 0 divided by anything is still 0, the slope is zero.

Answer:

no . 3

Step-by-step explanation:

a) 214 in base-five is 1324.

b) 62 in base-five is 222.

c) 8 in base-five is 13.

d) 95 in base-five is 340.

a) To determine the base five representation of 214, we need to   find the largest power of five that  is less than or equal to  214.

In this case, 125 (5³) is the largest power of five   that is less than 214.

Now, we divide 214 by 125 -  

214 ÷ 125 = 1 remainder 89

Next, we divide the remainder, 89, by the next lower power of five, which is 25 (5²) -  

89 ÷ 25 = 3 remainder 14

Finally, we divide the remaining 14 by the lowest power of five, which is 5 itself -  

14 ÷ 5 = 2 remainder 4

Therefore, the base-five representation of 214 is 1324 in base-five.

b) Following the same steps as above -  

62 ÷ 25 = 2 remainder 12

12 ÷ 5 = 2 remainder 2

Hence,  the base-five representation of 62 is 222 in base-five.

c) 8 ÷ 5 = 1 remainder 3

this menas that  the base-five representation of 8 is 13 in base-five.

d) Following the same steps as above -  

95 ÷ 125 = 0 remainder 95

95 ÷ 25 = 3 remainder 20

20 ÷ 5 = 4 remainder 0

Hence, the base-five representation of 95 is 340 in base-five.

Approximately 68% of the cases in a normal distribution are between 0.5 standard deviations above and below the mean.

To find the percentage of cases that are between 0.5 standard deviations above and below the mean, we can add these two probabilities:

34% + 34% = 68%

The normal distribution, also known as the Gaussian distribution or the bell curve, is a probability distribution that is widely used in statistics, science, and engineering. A bell-shaped curve that is symmetrical around the mean value best describes the distribution. The distribution's mean, median, and mode are all equal, and the standard deviation defines the curve's width.

Height, weight, IQ, and measurement mistakes are only a few examples of the numerous random variables and natural phenomena that follow the normal distribution. In addition, the central limit theorem predicts that regardless of the underlying distribution of the variables themselves, the total or average of several independent random variables with similar distributions will converge to a normal distribution. Because of this characteristic, the normal distribution is a key idea in inferential statistics and hypothesis testing.

Step-by-step explanation:

Yes , the integer k is divisible by 4 and statement (1) alone is sufficient to determine that k is divisible by 4.

Given data ,

Let the equation be represented as A

Now , the value of A is

a)

To determine if the integer k is divisible by 4, let's analyze the given statements:

Statement (1): 8k is divisible by 16.

This means that 8k is a multiple of 16. Since 16 is divisible by 4, we can conclude that k must be divisible by 4 as well. Therefore, statement (1) alone is sufficient to determine that k is divisible by 4.

8k = 16

k = 2

b)

This statement does not provide direct information about the divisibility of k by 4. While 12 is divisible by 4, the fact that 9k is divisible by 12 does not guarantee that k itself is divisible by 4.

9k = 12

k = 12/9

k = 4/3

So , it is not an integer

In conclusion, statement (1) alone is sufficient to determine that k is divisible by 4. Statement (2) is not sufficient on its own.

The minimum unit cost of the car is $12232.1

Given: cost function C(x)=0.9x² - 414x + 59,366

In order to find the minimum point, take the derivative of the cost function:

dC/dx = 2x - 414          (equate to zero and solve for x)

2x - 414 = 0                

2x = 414

x = 414/2 = 207

Thus, the minimum point is at x =207

The minimum unit cost can be obtained by substituting x = 207 into the cost equation:

C(x) = 0.9x² - 414x + 59,366

C(207) = 0.9(207)² - 414(207) +  59,366

          = 38564.1 - 85698 + 59,366

If one of the angle is 90 degrees, it would mean that he has drawn a right angle triangle.

Hypotenuse is the longest side of the triangle. We can find it using Pythagoras theorem as follows:

\(h=\sqrt{5^{2}+12^{2}}\\\\=13\)

The longest side is 13 cm.

If we keep the longest side the same and if two sides i.e. 5 cm and 12 cm are replaced, a new triangle can form.

The width is 8 cm and the length is 10 cm. Given that the length of a rectangle is 2 cm greater than the width and the area is 80 cm². We are to find the length and width.

The area of a rectangle is given as: A = l × w and the length is 2 cm greater than the width. l = w + 2 cm.

We are given that the area is 80 cm².

A = l × w₈₀

= (w + 2) × w₈₀

= w² + 2w.

Rearrange the terms to form a quadratic equation

w² + 2w - 80 = 0

We need to solve this quadratic equation using the formula as shown below: x = (-b ± sqrt(b² - 4ac))/(2a), Where a = 1, b = 2 and c = -80.

Substituting these values in the formula above:

x = (-2 ± √(2² - 4(1)(-80)))/2(1)x

= (-2 ± √(4 + 320))/2x

= (-2 ± √(324))/2.

We can simplify this expression by taking the square root of 324 which gives us:

x = (-2 ± 18)/2x₁

= (-2 + 18)/2

= 8 cm (Width)x₂

= (-2 - 18)/2

= -10 cm (Not possible as width cannot be negative).

Therefore, the length is:

l = w + 2 = 8 + 2

= 10 cm.
