Write the equation of a line that has a slope of -2/7 and passes through the point (5,-6)

**Answer:**

y = -2/7x - 32/7

**Step-by-step explanation:**

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

The slope is -2/7

y = -2/7 x+b

We know a point on the line is (5,-6)

Substitute this into the equation

-6 = -2/7(5) +b

-6 = -10/7+b

Add 10/7 to each side

-6 +10/7 = b

-42/7 + 10/7 = b

-32/7 = b

y = -2/7x -32/7

[tex]y = x + 4[/tex]

**Step-by-step explanation:**

Let [tex]P_1(-1, 3)[/tex] and [tex]P_2(0, 4)[/tex] and solve for the slope using the equation

[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{4 - 3}{0 - (-1)} = 1[/tex]

Therefore, the general slope-intercept form of the equation of the line is

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

where b is a constant. To solve for it, let's use one of the points. I'll use P2:

[tex]4 = (0) + b \Rightarrow b = 4[/tex]

Therefore, the slope-intercept form of the equation of the line is

[tex]y = x + 4[/tex]

What is the solution to this equation? 1⁵+5²/25⁰-5¹=

**Answer:**

It is 21 first guy is no doubt correct.

**Step-by-step explanation:**

The **expression results **to 21.

**Exponents **and **powers **can be used to represent **extremely **big or extremely small **numbers **in a more straightforward fashion.

For **example**, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as [tex]3^4[/tex], where 4 is the exponent and 3 is the base.

Given:

1⁵+5²/25⁰-5¹

So, 1⁵ = 1

5² = 25

25⁰ = 1

5¹ = 5

Now, 1⁵+5²/25⁰-5¹

= 1+ 25 / 1 - 5

= 1 + 20

= 21

Hence, the **expression** **results **to 21.

A steep mountain is inclined 74 degrees to the horizontal and rises 3150 feet above the surrounding plain. A cable for a cable car is to be installed from a point 725 feet from the base to the top of the mountain. Find the length of cable needed.

Answer:

3546 ft

Step-by-step explanation:

First find length of base to center of mountain.

(3150*sin 16 deg)/(sin 74 deg) = ~903 ft

Then dist of point from centre of mountain

903+725=1628 ft

Then cable length

(3150^2 + 1628^2)^0.5 = ~3546 ft

What is the slope and y-intercept that represents this table?

Answer:

[tex]m=-2\ 000; q=17\ 000[/tex]

Step-by-step explanation:

First of all, whoever formatted that table is a criminal.

Now, slope first, it's the easiest: the slope in a table like that is the difference between two consecutive position: ie [tex]13\ 000 - 15\ 000[/tex] or [tex]11\ 000-13\ 000[/tex], being careful of subtracting the higher position (not value!) minus the lower, or right minus left. Your slope thus is [tex]-2 \ 000[/tex]. Intercept is found in two ways. One is writing the line in point slope form based on any two values and the slope we found, or since we're jumping integer to integer, you can look at the table in reverse and notice that if you go backwards (ie from 4 to 3 to 2 to 1) the value is increasing by 2000 every time. The intercept [tex]q[/tex]will be the value at 0, or 17 000

What is the equation of the line that passes through the point (-6,8) and has an undefined slope?

**Answer:**

**Step-by-step explanation:**

Slope is rise over run (change in y divided by change in x), and to have an undefined slope change in x must be zero. The line x = -6 is a vertical line that passes through the point (-6,8).

What is Power rule, Product rule, Quotient rule and Chain rule? Detail please

Power Rule|

When raising an exponential expression to a new power multiply the exponents.

For and Example|

Simplify: 7a^4 b^6)2

Solution: Each factor within the parentheses should be raised to the 2nd power.

7a^4 b^6)2 = 7^2(a4)2(b^6)2

You then simplify using the power Rule of Exponents.

7a^4 b^6)2 = 7^2(a4)2(b^6)2 = 49a^8 b^12

The power rule states that this derivative is n times the function raised to the (n-1) the power times the derivative of the function.

Product Rule|

When multiplying exponential expressions that have the same base, add the exponents.

Example:

Multiply: 4x^3 • -6x^2

Solution:

Multiply coefficients: 4 • -6 = -24

Use the product rule to multiply variables.

X^3 • x^2 = x^3 + 2 = x^5

4x^3 • -6x^2 = -24x^5

The power of product rule is a method for simplifying exponents and it states that a term raised to a power is equal to the product of its factors raised to the same power.

The product of two or more numbers is the result of multiplying these numbers.

Quotient Rule|

When dividing exponential expressions that have the same base, subtract the exponents.

Example:

Simplify: 8x^6/2x^3 = 4x^3

Solution:

Divide coefficients:

8 /2 = 4

Use the Quotient rule to divide variables:

X^6/x^3 = x6 - 3 = x^3

8x^6/ 2x^3 = 4x^3

The Quotient of two numbers is the result of the division of the numbers.

Chain Rule|

The general power rule is a special case of the chain rule. It is useful when finding the derivative of a function that is raised to the nth power.

**Answer:**

Question 4: Which equation is parallel to the above equation and passes through the point (35, 30)

[tex]y=[/tex] [tex]\frac{5}{7} x + 5[/tex] is the correct answer, I found this by inputting the x and y value of the coordinate (35, 30) onto the equation and solving for y-intercept since the slope of all equations is the same (since it's traveling parallel)

[tex]30 = \frac{5}{7} (35) + y\\30 = 25 + y\\5 = y[/tex]

so the equation would be [tex]y=[/tex] [tex]\frac{5}{7} x + 5[/tex]

Question 5: Which equation is perpendicular to the above equation and passes through the point (35, 30)

[tex]y=\frac{-7}{5} x+79[/tex] is the correct answer, I found this using the same method as before, input coordinate values into the equation and solve for the y-intercept (The only thing changed from the last answer is the opposite reciprocal slope).

[tex]30 = \frac{-7}{5}(35) + y \\30 = -49 + y \\79 = y[/tex]

so the equation would be [tex]y=\frac{-7}{5} x+79[/tex]

A race director is preparing for an upcoming marathon and estimates that the mean time to

finish is 310 minutes. Assume

that the times are normally distributed, with a standard deviation of 50 minutes.

Use a standard normal table or a calculator to find the percentage of times that are longer than 236 minutes. For your

intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example

98.23%).

**93.06% **of the race is longer than **236 minutes**.

The** z score** is used to** determine **by how many **standard deviations **the **raw score** is above or below the** mean**. The **z score** is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]

Given that μ = 310, σ = 50

For **x > 236**:

[tex]z=\frac{236-310}{50}=-1.48[/tex]

From the normal distribution table:

P(x > 236) = P(z > -1.48) = 1 - P(z < -1.48) = 1 - 0.0694 = 0.9306 = **93.06%**

**Answer:**

**Step-by-step explanation:**

each zero of the function will have a factor of (x - x₀)

h(x) = a(x + 3)(x + 2)(x - 1)

h(x) = a(x + 3)(x² + x - 2)

**h(x) = a(x³ + 4x² + x - 6)**

or the third option works if a = 1

however this equation gives us the points (0, -6) and (-1. -4), so "a" must be -2

h(x) = -2x³ - 8x² - 2x + 12

to fit ALL of the given points as it fits the three zeros and also h(0) and h(-1) so I guess that is why the given group is a *partial* set of solution sets

A programmer plans to develop a new software system. In planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be % confident that his estimate is in error by no more than percentage point Complete parts (a) through (c) below.

A) Assume nothing is known about the percentage of computers with new operating systems

n =

round up to the nearest integer

b) Assume that the recent survey suggest that about 96% of computers use a operating system.

n =

round up to the nearest integer

C) Does the additional survey information from part (b) have much of an effect on the sample size that is required?

A.

Yes, using the additional survey information from part (b) dramatically reduces the sample size.

B.

No, using the additional survey information from part (b) does not change the sample size.

C.

Yes, using the additional survey information from part (b) dramatically increases the sample size.

D.

No, using the additional survey information from part (b) only slightly increases the sample size.

Using the **z-distribution**, we have that:

**a) **A **sample of 601 **is needed.

**b) **A **sample of 93** is needed.

**c) A. **Yes, using the additional survey information from part (b) dramatically reduces the sample size.

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following **confidence interval of proportions.**

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which **z** is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].

The **margin of error** is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

**95% confidence** level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].

For this problem, we consider that we want it to be **within 4%.**

Item **a:**

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.04 = 1.96\sqrt{\frac{0.5(0.5)}{n}}[/tex]

[tex]0.04\sqrt{n} = 1.96\sqrt{0.5(0.5)}[/tex]

A **sample of 601 **is needed.

Item **b:**

The **estimate **is [tex]\pi = 0.96[/tex], hence:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.04 = 1.96\sqrt{\frac{0.96(0.04)}{n}}[/tex]

[tex]0.04\sqrt{n} = 1.96\sqrt{0.96(0.04)}[/tex]
