The points (j, - 8) and (1, - 2) fall on a line with a slope of - 6. What is the value of j?

Answers

Answer:
j = 2

Explanation:
Slope of the line can be calculated using the following rule:
slope = [tex] \frac{y2-y1}{x2-x1} [/tex]

We are given:
slope = -6
point (j,-8) representing (x1,y1)
point (1,-2) representing (x2,y2)

Substitute with the givens in the above equation and solve for j as follows:
slope = [tex] \frac{y2-y1}{x2-x1} [/tex]
-6 = [tex] \frac{-2-(-8)}{1-j} [/tex]
-6(1-j) = -2-(-8)
-6 + 6j = 6
6j = 6+6 = 12
j = 12/6
j = 2

The population of a city in 2005 was 18000. By 2010, the city’s population had grown to 45,000. Economists have determined that the growth is exponential. If they are correct, what is the projected population for 2015?

Answers

first do 45000-18000=27,000
and approx projected population is 45,000+18000=63,000
your answer is 63,000

Solution:

we are given that

The population of a city in 2005 was 18000.

By 2010, the city’s population had grown to 45,000.

Economists have determined that the growth is exponential.

As we know the exponential growth is defined by the relation

[tex]P=p_0e^{rt}\\ \\ \text{where P is the population at time t and initial population is } p_0\\[/tex]

Here we have [tex]p_0=18000, P=45000, t=5[/tex]

substitute these values we get

[tex]45000=18000e^{5r}\\ \\ r=0.183[/tex]

So we get

[tex]P(t)=18000e^{0.183t}[/tex]

So For population is 2015 substitute t=10

[tex]P(10)=18000e^{0.183*10}[/tex]

[tex]P(10)=112209.9598 [/tex]

The projected population for 2015 is 112210

Mrs. Bowen told Mr. Bowen that there is no way he is way he is spending that much money on golf clubs. instead she wants to buy a new flat screen television for the living room. Walmart has a 55 inch ultra slim HDTV flat screen that is normally $1099.99 but its on sale for 42% off. The sales tax on the TV will be 6.5%. How much will the final price of the TV be?
Can you please explain how to do it?

Answers

Hi there!
Sounds confusing, I know.

But let me try to explain.
First we need to subtract the discount from the total.

1099.99- 42%= 637.99

So, 637.99 is our new total, but wait!
We have to add the SALES TAX!! That’s kind of important. ; )

Okay so now let’s take our new total and then add the tax.

637.99+ 6.5%= 679.45

And... there we have it. $679.45 for that beautiful flat screen tv.
Looks like the Bowen’s are in for some big savings! Maybe they can buy those golf clubs after all...

Have a terrific day! I hope I have successfully helped you.

Find the sum. 13(9−6m)+14(12m−8)

Answers

Final answer:

To solve the expression 13(9−6m)+14(12m−8), distribute the numbers and combine like terms to get the sum, which is 90m + 5.

Explanation:

To find the sum of the expression 13(9−6m)+14(12m−8), we need to distribute the numbers outside the parentheses across the terms inside the parentheses and then combine like terms.

Distribute the numbers:

13 × 9 = 117

13 × (−6m) = −78m

14 × 12m = 168m

14 × (−8) = −112

Now we combine like terms:

117 (−78m) + (168m − 112)

Simplifying this we get:

−78m + 168m = 90m

−112 + 117 = 5

So the sum is 90m + 5.

Rewrite the following equation in slope-intercept form. 19x − 20y = -13 Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Y= 0

19x = -13
X= -13/19

X=0

-20y=-13
Y= 13/20

Final answer:

To rewrite the equation 19x - 20y = -13 in slope-intercept form, you subtract 19x on both sides and then divide by -20 to isolate y. The resulting equation is y = (19/20)x + 13/20.

Explanation:

To rewrite the equation 19x - 20y = -13 in slope-intercept form, follow these steps:

Move 19x to the other side by subtracting it from both sides: -20y = -19x - 13

Divide by -20 to isolate y: y = (19/20)x + 13/20

Therefore, the equation in slope-intercept form is y = (19/20)x + 13/20.

List all subsets of the following set: {dog, cat, fish}

Answers

There are 8 subsets here. We have the original set {dog, cat, fish} which we can list the items in any order we want.

Then we have the set of items where we only pick two pets
{dog, cat}
{dog, fish}
{cat, fish}
the order for any given set does not matter

Then we have the set of just one pet only
{dog}
{cat}
{fish}

And finally, we have the empty set { } which is just curly braces with nothing inside.

In summary, we have these 8 subsets
{dog, cat, fish}
{dog, cat}, {dog, fish}, {cat, fish}
{dog}, {cat}, {fish}
{ }

Note how this is equal to 2^n = 2^3 = 8. The n = 3 indicates how many items are in the original set. The set of all possible subsets is known as the power set.

A wire is stretched from the top of an 8 ft. pole to a bracket 5 ft. from the base of the pole. How long is the wire?

Answers

pathagorean theorem:
[tex] {a}^{2} + {b}^{2} = {c }^{2} \\ {8}^{2} + {5}^{2} = {c}^{2} \\ 64 + 25 = {c}^{2} \\ 89 = {c}^{2} \\ \sqrt{89 } = \sqrt{ {c}^{2} } \\ the \: wire \: is \: 9.43ft[/tex]

The length of the stretched wire is required.

The length of the wire is 9.43 feet.

Pythagoras theorem

b = Length of the pole = 8 ft

a = Distance between bracket and base of pole = 5 ft

c = Length of wire

The two lengths form a right triangle.

From the Pythagoras theorem we have

[tex]c^2=a^2+b^2\\\Rightarrow c=\sqrt{a^2+b^2}\\\Rightarrow c=\sqrt{8^2+5^2}\\\Rightarrow c=9.43\ \text{feet}[/tex]

vivien's handspan measure 18.5 centimeters.estimate the number of times Vivien uses her handspan to measure a length of 1 meter 75 centimeters

Answers

1.75 meters is 175 centimeters
Estimate what is 175 ÷ 18.5 . It cant be 10 because 18.5 is 185 which is greater than 175 , so lets estimage Vivien will have to use her handspan 9 times.

Final answer:

Vivien would use her handspan, which measures 18.5 centimeters, approximately 9 times to measure a length of 1 meter 75 centimeters. This estimate assumes precision in her handspan measurement.

Explanation:

To estimate the number of times Vivien uses her handspan to measure a length of 1 meter 75 centimeters, we need to divide the total length by the length of her handspan. Since Vivien's handspan measures 18.5 centimeters, and the total length to measure is 1 meter 75 centimeters (which equals 175 centimeters), we perform the following calculation:

Convert 1 meter 75 centimeters to all centimeters: 1 meter = 100 centimeters, so 1 meter 75 centimeters = 100 + 75 = 175 centimeters.Divide the total length by the length of Vivien's handspan: 175 cm/18.5 cm =9.45945945945946Round the result to the nearest whole number to estimate the number of handspans: approximately 9 times (since we typically round down when the decimal is less than 0.5).

This is an estimation technique that assumes Vivien's measurement with her handspan is accurate. The accuracy of this measurement can vary based on several factors, including the precision of Vivien's handspan and the method used for measuring.
