A Line Passes Through The Point (8,-9) And Has A Slope Of -5/4. Write An Equation In Point-slope Form.

Answers

Answer 1

Answer:

 y=-5/4x-19

Step-by-step explanation:

y=-5/4(x(-8))-9

y=-5/4x-10-9

y=-5/4x-19

Answer 2
1. Slope
M = -5/4

2. Y- intercept
Y = mx + b
-9 = (-5/4)(8) + b
-9 = -10 + b
-9 + 10 = -10 + 10 + b (the ten cancels out and we are just left with our b)
1 = b

So, therefore, the equation is:
Y = -5/4x + 1

Answer/Step-by-step explanation:

Area of trapezium = ½*(AD + BC)*AB

Area = 42 cm²

AD = (x + 8) cm

BC = (x + 5) cm

AB = x cm

Plug in the values into the equation

42 = ½((x + 8) + (x + 5))*x

42 = ½((x + 8 + x + 5)*x

42 = ½(2x + 13)*x

Multiply both sides by 2

42*2 = (2x + 13)*x

84 = 2x² + 13x

2x² + 13x = 84

Subtract both sides by 84

2x² + 13x - 84 = 0

In a study of facial behavior, people in a control group are timed for eye contact in a 5- minute period. Their times are normally distributed with a mean of 184 seconds and a standard deviation of 55 seconds. For a randomly selected person from the control group, find the probability that the eye contact time is greater than 230 seconds

Answers

Answer:

0.20148

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = 230

μ is the population mean = 184

σ is the population standard deviation = 55

z = 230 - 184/55

z = 0.83636

P-value from Z-Table:

P(x<230) = 0.79852

P(x>230) = 1 - P(x<230) = 0.20148

Therefore, the probability that the eye contact time is greater than 230 seconds is 0.20148

Hadley was going out with her friends for dinner. The equation c = x + 0.07x + 0.18x gives the total cost c of her meal, where x is the cost before tax and tip. The restaurant charges 7% sales tax and she plans to leave an 18% tip. She knew that she can only spend $18. What is the maximum amount Hadley can spend before tax and tip?

Answers

Answer:

$14.4

Step-by-step

c = x + 0.07x + 0.18x

18 = x + 0.07x + 0.18x

18 = 1.25x (simplify)

14.4 = x  (divide both sides by 1.25)

X = ?

Answers

Answer:

80.4

Step-by-step explanation:

Use the tan formula

The value of X is approximately 80.38 units.

Here, we have,

To find the value of X, we can use trigonometric functions.

In this case, we'll use the tangent function, which relates the angle and the sides of a right triangle.

The tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

In this scenario, we have the angle between the hypotenuse and the base as 15°, and the base of the triangle is given as 300 units.

Using the tangent function, we can set up the equation:

tan(15°) = X / 300

Now, let's solve for X:

X = 300 * tan(15°)

Using a calculator, we find:

X ≈ 80.384

Rounding to the nearest tenth, the value of X is approximately 80.38 units.

2) What is the decimal equivalent of your two examples?

3) Can every repeating decimal be written as a rational number? Explain why or why
not.

Answers

Answer:

Step-by-step explanation:

A rational number is one that can be expressed as a fraction. Pi cannot be. If I tell you that the 2000th digit of pi is an 8 (which it probably isn't) and I ask you to tell me the 2001 value of pi, you have no better odds that 1/10 of getting it right.

A rational number can always be reduced to a fraction. 20 1/2 can be expressed as a fraction. It is 20.5

Pi is irrational. I don't know the value of pi beyond what a calculator can tell me.  3.14159265 The next digit is a 4. I know this only because that is what the calculator tells me.

Repeating decimals call always be represented as a fraction. For ex

x = 0.123123123123123

1000x = 123.123123123123

       x =       .123123123123123      Subtract

999x = 123

This comes about because in both cases what is after the decimal is the same.

x = 123/999 = 41/333

Aden gets paid daily for the work she does and she does not work on Sundays. Last year which was n ot a leap year had 52 Sundays. She got Dhs 354003 as her annual salary last year. If the March of last year had 5 Sundays, how much did she earn in that month?

Answers

Answer: Dhs 29312.4

Step-by-step explanation:

For a leap year, we should note that there are 366 days. Since there were 52 Sundays, the number of days worked by Aden will be:

= 366 - 52

= 314 days

Since she got Dhs 354003 as her annual salary last year, the amount received per day will be:

= 354003 / 314

= Dhs 1127.4

The amount earned in March will be:

= (31 - 5) × 1127.4

= 26 × 1127.4

= Dhs 29312.4

Find the measure of the numbered angle

Answers

angle 1: 50
angle 2: 130
angle 3: 50
angle 4: 130
angle 5: 40
angle 6: 140
angle 7: 90
angle 8: 140

Answer:

1 = 50°,  2 = 130°,  3 = 50°,  4 = 130°,  5 = 40°,  6 = 140°,  7 = 90°,  8 = 140°

Step-by-step explanation:

The sum of the angles of a triangle is 180°. A flat angle measures 180° as well.

Angle 1: 180 - 90 - 40 = 50°

Angle 2: 180 - 50 = 130°

Angle 3: 180 - 130 = 50°

Angle 4: 180 - 50 = 130°

Angle 5: 180 - 90 - 50 = 40°

Angle 6: 180 - 40 = 140°

Angle 7: 180 - 90 = 90°

Angle 8: 180 - 40 = 140°
