Since slope is calculated using the formula m = StartFraction v 2 minus v 1 Over x 2 minus x 1 EndFraction, the slope of both lines is equivalent to ________. It is given that the lines are parallel, and we calculated that the slopes are the same. Therefore, parallel lines have the same slopes.

Answers

Answer: z-v/x-w

Step-by-step explanation: just did the test with this question and it’s right :)

Final answer:

Parallel lines have the same slopes.

Explanation:

The subject of this question is Mathematics as it involves calculating slopes using a formula.

Slope is calculated using the formula m = (v2 - v1) / (x2 - x1). When two lines are parallel, their slopes are equivalent, meaning that they have the same slope. This is because parallel lines have the same steepness or inclination.

For example, if Line A has a slope of 2 and Line B is parallel to Line A, then Line B will also have a slope of 2.

You have 5,814 feet of rope that you need to cut into 27-foot sections. How many sections of rope will you have?a. 215 sections with 8 feet left over
b. 215 sections with 9 feet left over
c. 218 sections with 3 feet left over
d. 215 sections with 3 feet left over

Answers

The answer is d. 215 sections with 3 feet left over

To calculate this, divide the length of the rope (l1) by the length of the section (l2).
n - number of sections

n = l1/l2
l1 = 5,814 ft
l2 = 27 ft

n = 5,814 / 27 = 215.3 sections
215.3 sections can be written as 215 (whole) sections with 3 ft left over.

A cosmetics company that makes small cylindrical bars of soap wraps the bars in plastic prior to shipping. Find the surface area of a bar of soap if the diameter is 5cm and the height is 2cm.

Answers

we would have two circles of 5cm diameter each, and a rectangle of the length pi*diameter and 2cm, so lets add them:
total = 2circles + rectangle
total = 2(2*pi*(5/2)^2) + pi*diameter*heigth
= 4*pi*(2.5)^2 + pi*5*2
= 109.9
that is the surface area of a bar soap 109.9 cm^2

The formula you use is pi x radius ^ 2 + pi x radius x l ( l stands for lateral height)
pi x 2.5^2 + pi x 2.5(2)
3.14 x 6.25 + 3.14 x 5
19.6 + 15.7
= 35.3 cm^2

Find f(x) and g(x) so the function can be expressed as y = f(g(x)) y = Seven divided by x squared. + 10

Answers

f(x) = 7/x
g(x)=x²+10

Then f(g(x))= 7/(x²+10)

By the way g(f(x))=(7/x)² + 10

Answer:

f(x) = $(7)/(x^(2) )$ + 10
g(x) = $(7)/(x^(2) )$

Step-by-step explanation:

Given that:

y = f(g(x)) = $(7)/(x^(2) )$ + 10

It is obviously that g(x) is put as an independent variable of f(x) to have the equation of y written above.

f(x) = $(7)/(x^(2) )$ + 10
g(x) = $(7)/(x^(2) )$

Hope it will find you well.

Answer:

Step-by-step explanation:

1) We would determine the cube root of 27 and find its square.

Cube root of 27 = 3

3² = 9

Solution = 9

2) 36³ = 46656

√36³ = √46656 = 216

3) we would find the 5th roof of - 243 and find its cube

5th root of - 243 = - 3

- 3³ = - 27

Solution = - 27

4) Looking at the expression, 40⅔, we can see that

a = 2

b = 3

c = 40

What is (7/12)/(5/9)? In simplest form..

Answers

$(7)/(12) / (5)/(9) =$

Change the division to multiplication through the reciprocal of the number being divided.

$(7)/(5) * (9)/(5) = (21)/(20)$

As mixed number:

$1 (1)/(20)$

7/12 times 5/9 equals 35/108. It is automatically in simplest form.
