Which of the following linear equations describes that relationship?

JulsSmile [24]

Answer:

D. f(x) = 4x - 3

Step-by-step explanation:

Use two pairs of points to work out the equation:

(1, 1) and (2, 5)

Find the slope:

m = (5 - 1) / (2 - 1) = 4/1 = 4

Find the y-intercept:

1 = 4*1 + b
b = 1 - 4
b = - 3

The line is:

f(x) = 4x - 3

Correct choice is D

Can u guys please answer these Pythagoras theorem questions. First person to answer this questions will be marked as brainest an

VashaNatasha [74]

Answer:

d. 21.5

Step-by-step explanation:

To find the missing side length of each triangle, use the pythagorean theorem. The theorem is $a^2 + b^2 = c^2$ where a, b, and c are all side lengths of the triangle. a is the smallest lef and b is the other leg while c is always the hypotenuse or longest side.

In d, you'll use it twice to find the missing measure. First use it when a = 12 and b = 20. So you'll have:

$12^2 + 20^2 = c^2\\144 + 400 = c^2\\544 = c^2\\\sqrt{544} = c\\ 23.32 = c$

Repeat the same process using a = 9 and c = 23.32. Then solve for the b value.

$9^2 + b^2 = 23.32^2\\81 + b^2 = 544\\b^2 = 544 - 81\\b^2 = 463\\b = \sqrt{463} \\b = 21.5$

A triangular pane of glass has a height of 30 inches and an area of 270 square inches. what is the length of the base pane

Tems11 [23]

The equation for the area of a triangle is A= b*h /2. So, plug in your known variables, and you get 270in^2= b*30 /2. First you multiply by 2 to cancel out the division for 2, which gets you 540= b* 30. To get "b" by itself, divide both sides by 30, giving you 18=b.

To check this, plug in your new known variable, as 270= 18* 30 /2. This will equal as 270=270, confirming 18in as the correct measurement.

Type the correct answer in each box. Spell all words correctly, and use numerals instead of words for numbers.

Andru [333]

Answer:

Nate made a mistake. He should have got 24 as Least common factor.

Step-by-step explanation:

Given number are 8 and 12.

To find the GCF or LCF we have to list multiples.

For LCF

List the multiples of each number until at least one of the multiples appears on all lists.
Find the smallest number that is on all of the lists.
This number is the LCM.

For GCF

List the multiples of each number until at least one of the multiples appears on all lists.
Find the Biggest number that is on all of the lists.
This number is the GCF

The least common multiple of 8 and 12 is 24.

The Greatest common multiply of 8 and 12 is 4.

Hence, Nate is wrong. Nate should have found 24.

Past experience has indicated that the breaking strength of yarn used in manufacturing drapery material is normally distributed.

OLEGan [10]

Answer: the value of population standard deviation is 3.87

Step-by-step explanation:

From the information given,

Number of sample, n = 8

For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.

We will apply the formula

Confidence interval

= mean ± z ×standard deviation/√n

Since confidence interval = 2.694,

It becomes

2.694 = 1.96 × standard deviation/√8

Dividing both sides of the equation by 1.96, it becomes

1.37 = standard deviation/√8

Standard deviation = 1.37 × √8

Standard deviation = 3.87
