Answer:

The equation of the line in slope-intercept formula is [tex]y = \frac{x}{6} - 5[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line, in slope-intercept formula, is given by:

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

In which m is the slope and b is the y-intercept(value of x when y = 0).

In this question:

[tex]18y - 3x = -90[/tex]

Isolating y:

[tex]18y = 3x - 90[/tex]

[tex]y = \frac{3x}{18} - \frac{90}{18}[/tex]

Simplifying the fractions:

[tex]y = \frac{x}{6} - 5[/tex]

The equation of the line in slope-intercept formula is [tex]y = \frac{x}{6} - 5[/tex]

Answer:

[tex]p \± ME[/tex] [tex]\to[/tex] [tex]71.2\% \± 7.9\%[/tex]

Step-by-step explanation:

Given

[tex](63.3\%,79.1\%)[/tex]

Required

Express in form of: [tex]p \± ME[/tex]

First, calculate the midpiont (p)

[tex]p = \frac{63.3\% + 79.1\%}{2}[/tex]

[tex]p = \frac{142.4\%}{2}[/tex]

[tex]p = 71.2\%[/tex]

The margin of error (ME) is:

[tex]ME =79.1\% - 71.2\%[/tex]

[tex]ME =7.9\%[/tex]

So, we have:

[tex]p \± ME[/tex] [tex]\to[/tex] [tex]71.2\% \± 7.9\%[/tex]

Answer:

p = 10.8

Step-by-step explanation:

Given that p is directly proportional to (p-1)² and p is always positive, then;

q = k (p-1)²

If q = 30 and p = 7

30 = k(7-1)²

30 = 6²k

30 = 36k

5 = 6k

k = 5/6

To get p when q = 80

q =k (p-1)²

80 = 5/6((p-1)²

480 = 5(p-1)²

480/5 = (p-1)²

(p-1)² = 96

p-1 = √96

p-1 = 9.8

p = 9.8 + 1

p = 10.8

Answer:

16m 24m and 24m

Step-by-step explanation:

Given the fact that it's a rectangle, and 1 side is 16m, we know that 1 of the other sides will be 16m. After that and some simple subtraction, we get the other 2 sides are 24m.

Answer:

2.25 Gallons.

Step-by-step explanation:

A pint is [tex]\frac{1}{8} th[/tex] of a gallon or 0.125.

Multiply 18 pints by 0.125.

18 · 0.125 = 2.25

To Check Work:

Divide 2.25 by 0.125 to equal 18.

[tex]\frac{2.25}{0.125} = 18[/tex]

Divide 2.25 by 18 to equal 0.125.

[tex]\frac{2.25}{18} = 0.125[/tex]

Joule’s law is a mathematical description of the rate at which resistance in a circuit converts electric energy into heat energy.

Mathematically

Q = I^2 R T

Where,

Q indicates the amount of heat

I show electric current

R is the amount of electric resistance in the conductor

T denotes time

Answer:

the answer is d because that is how much degrees it is

Step-by-step explanation:

Given:

The length of the ladder  = 12 ft

The angle of ladder with ground = 60 degrees

To find:

How far up the building the ladder will reach.

Solution:

Using the given information draw a figure as shown below.

We need to find the vertical distance between the top of ladder and the ground.

Let x be the required distance.

In a right angle triangle,

[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]

In the below triangle ABC,

[tex]\sin A=\dfrac{BC}{AC}[/tex]

[tex]\sin 60^\circ=\dfrac{x}{12}[/tex]

[tex]\dfrac{\sqrt{3}}{2}=\dfrac{x}{12}[/tex]

Multiply both sides by 12.

[tex]\dfrac{\sqrt{3}}{2}\times 12=x[/tex]

[tex]6\sqrt{3}=x[/tex]

Therefore, the ladder will reach [tex]6\sqrt{3}[/tex] ft far up the building.

Answer:

The exponential model n(t) is [tex]n(t) = 46(1.1487)^t[/tex]

Step-by-step explanation:

Exponential model of population growth:

An exponential model for population growth has the following model:

[tex]n(t) = n(0)(1+r)^t[/tex]

In which n(0) is the initial value and r is the growth rate, as a decimal.

Observed to double every 5 hours.

This means that [tex]n(5) = 2n(0)[/tex]

We use this to find 1 + r. So

[tex]n(t) = n(0)(1+r)^t[/tex]

[tex]2n(0) = n(0)(1+r)^5[/tex]

[tex](1+r)^5 = 2[/tex]

[tex]\sqrt[5]{(1+r)^5} = \sqrt[5]{2}[/tex]

[tex]1 + r = 2^{\frac{1}{5}}[/tex]

[tex]1 + r = 1.1487[/tex]

So

[tex]n(t) = n(0)(1+r)^t[/tex]

[tex]n(t) = n(0)(1.1487)^t[/tex]

Initially has 45 bacteria

This means that [tex]n(0) = 45[/tex]. So

[tex]n(t) = n(0)(1.1487)^t[/tex]

[tex]n(t) = 46(1.1487)^t[/tex]

The exponential model n(t) is [tex]n(t) = 46(1.1487)^t[/tex]

Answer:

0, - 1.732 , 1.732

Step-by-step explanation:

The slope of the line is the angle of the tangent from the positive X axis in counter clock wise direction.

The slope of line AB is

tan 180 = 0

The slope of line BC is

tan 300 = - 1.732

The sloe of line AC is

tan 240 = 1.732

Answer:

red: 12/35

yellow: 18/35

blue: 1/7

Step-by-step explanation:

The experimental probability is the total number of each outcome over the total outcomes. The total outcomes would be the sum, 12 + 18 + 5, or 35.

If we are looking for the experimental probability of red, we divide the spins on red by the total:

red - [tex]\frac{12}{35}[/tex]

If we are looking for the experimental probability of yellow, we divide the spins on yellow by the total:

yellow - [tex]\frac{18}{35}[/tex]

If we are looking for the experimental probability of blue, we divide the spins on blue by the total:

blue - [tex]\frac{5}{35}[/tex] = [tex]\frac{1}{7}[/tex]

Answer:

456,796 passwords

Step-by-step explanation:

Because any letter can be repeated for the 4-letter password, there are 26 possible letters for the first letter of the password, 26 possible letters for the second letter of the password, 26 possible letters for the third letter of the password, and 26 possible letters for the fourth letter of the password. Therefore, the possible number of passwords that can be created is 26*26*26*26 = 26^4 = 456,796 passwords

Answer:

The town's annual energy consumption will be of 6.57 trillons of BTU after 9 years.

Step-by-step explanation:

The annual energy consumption of the town where Camilla lives increases at a rate that is proportional at any time to the energy consumption at that time.

This means that the consumption after t years is given by the following differential equation:

[tex]\frac{dC}{dt} = kC[/tex]

In which k is the growth rate.

The solution is, applying separation of variables:

[tex]C(t) = C(0)e^{kt}[/tex]

In which C(0) is the initial consumption.

The town consumed 4.4 trillion British thermal units (BTUs) initially.

This means that [tex]C(0) = 4.4[/tex]

So

[tex]C(t) = C(0)e^{kt}[/tex]

[tex]C(t) = 4.4e^{kt}[/tex]

5.5 trillion BTUs annually after 5 years.

This means that [tex]C(5) = 5.5[/tex]. We use this to find k. So

[tex]C(t) = 4.4e^{kt}[/tex]

[tex]5.5 = 4.4e^{5k}[/tex]

[tex]e^{5k} = \frac{5.5}{4.4}[/tex]

[tex]e^{5k} = 1.25[/tex]

[tex]\ln{e^{5k}} = \ln{1.25}[/tex]

[tex]5k = \ln{1.25}[/tex]

[tex]k = \frac{\ln{1.25}}{5}[/tex]

[tex]k = 0.0446[/tex]

So

[tex]C(t) = 4.4e^{0.0446t}[/tex]

After 9 years?

This is C(9). So

[tex]C(9) = 4.4e^{0.0446*9} = 6.57[/tex]

The town's annual energy consumption will be of 6.57 trillons of BTU after 9 years.
