What is the equation of the line that passes through the point (5,-1) and has a slope of a fraction 1/5

Answers

Answer:

Equation will be y = 5x + c

Step-by-step explanation:

For point (5, 1)

1 = 5(5) + c

Or, c = - 24

The women of latvia are the tallest in the world with an average height of 170 cm, which is what in feet and inches?.

Answers

Step-by-step explanation:

Convert the given value in cm into feet and inches.

Use the unit rates:

1 foot = 30.48 cm1 inch = 2.54 cm

Convert:

170 cm = 170/30.48 feet = 5.58 feet (rounded)170 cm = 170/2.54 inches = 66.93 inches

or

170 cm = 5 feet and 17.6 cm = 5 feet and 7 inches (rounded)

[25 POINTS] A cylinder has a volume of 400π cm3. Find the dimensions that minimize its surface area.

Answers

Answer:

r = 5.848cm, h = 11.696cm

Step-by-step explanation:

Surface area: [tex]SA=2\pi rh+2\pi r^2[/tex]

Volume: [tex]V=\pi r^2h[/tex]

Therefore, the height of a cylinder given its volume would be [tex]h=\frac{V}{\pi r^2}[/tex], thus:

[tex]SA=2\pi r(\frac{V}{\pi r^2})+2\pi r^2\\\\SA=\frac{2V}{r}+2\pi r^2\\\\SA=\frac{2(400\pi)}{r}+2\pi r^2\\\\SA=\frac{800\pi}{r}+2\pi r^2[/tex]

We now find the derivative of the surface area of the cylinder with respect to its radius and set it equal to 0, solving for the radius:

[tex]\frac{d(SA)}{dr}=-\frac{800\pi}{r^2}+4\pi r[/tex]

[tex]0=-\frac{800}{r^2}+4\pi r[/tex]

[tex]0=800\pi+4\pi r^3[/tex]

[tex]-800\pi=4\pi r^3[/tex]

[tex]-200=r^3[/tex]

[tex]r\approx5.848[/tex]

If [tex]0If [tex]r>5.848[/tex], then the surface area of the cylinder increases

Therefore, the surface area is minimized when the radius is [tex]r=5.848cm[/tex], making the minimum height [tex]h=\frac{V}{\pi r^2}=\frac{400\pi}{\pi(5.848)^2}\approx11.696cm[/tex].

In conclusion, the 2nd option is correct.

The school store sells pencils and erasers.
• For 3 pencils and 2 erasers, the cost is $0.76.
• For 2 pencils and 4 erasers, the cost is $1.04.
How much more does 1 eraser cost than 1 pencil?

Answers

Answer:

$0.18

Step-by-step explanation:

we need to set up two simultaneous equations

using variables, pencils = p and erasers = e

3 pencils and 2 erasers, the cost is $0.76

3p + 2e = $0.76

2 pencils and 4 erasers, the cost is $1.04.

2p + 4e = $1.04

we now have

3p + 2e = $0.76

2p + 4e = $1.04

to make the number of erasers the same, multiply the first equation by 2 to give 4e

2(3p + 2e = $0.76)

6p + 4e = $1.52

now we have the same number of erasers for both equations

6p + 4e = $1.52

2p + 4e = $1.04

subtract across: 6p - 2p = 4p, 4e - 4e = 0, $1.52 - $1.04 = $0.48

we are left with 4p = $0.48

divide both sides by 4

p = $0.12

1 pencil = $0.12

go back to the start of both equations and use one of them to find 1 eraser. I'll use 3p + 2e = $0.76

input $0.12 in p

3($0.12) + 2e = $0.76

$0.36 + 2e = $0.76

subtract $0.36 on both sides

2e = $0.76 - $0.36

2e = $0.40

divide 2 on both sides

e = $0.20

1 eraser = $0.20

How much more does 1 eraser cost than 1 pencil?

we now know 1 pencil = $0.12 and 1 eraser = $0.20

find the difference between them

$0.20 - $0.12 = $0.18

final answer= $0.18

Solve the equation q+5/9=5/6 q=?

Answers

Answer:

q = 5/18

Step-by-step explanation:

q + 5/9 = 5/6

Subtract 5/9 from each side

q + 5/9 - 5/9 = 5/6 - 5/9

q = 5/6 - 5/9

Get a common denominator of 18

q = 5/6 *3/3 - 5/9 *2/2

q = 15/18 - 10/18

q = 5/18

a) the formula is a(first term)+2(n-1) so the nth term is 29+2(n-1) and the 50th term is: 29+2(50-1)=29+2(49)=127
b) the formula is a(first term)-1(n-1) so the nth term is 118-(n-1) which is 118-n+1 and its simplest form is 119-n so the 50th term is gonna be like this: 119-50=69

The answer to this question is very simple 120.

You can even do it systematically.

Take a=114, d = a2 - a1 = 116 - 114 =2

So now you get, a1= 114, d = 2

Now you want the 4th term so,

a4 = a + (n-1)d

a4 = 114 + 3 (2)

a4 = 114 +6 = 120

The perimeter of a rectangle is 76. The length is 20 more than the width. Find the width and length.

Answers

Answer: The width is 9 units and the length is 20 units

Step-by-step explanation:

Perimeter is length + length + width + width, (P = 2l + 2w)

76 = 2(w+20) + 2w

76 = 2w + 40 + 2w

76 = 4w + 40

Subtract 40 on both sides

36 = 4w

Divide both sides by 4

9 = w

That means the length is 29 and the width is 9. To check out work, add 29+29+9+9 to get 76. Our answer is correct.
