Answer:

Step-by-step explanation:

y =4/3 x+4

slope intercept form

y = mx+b

the y intercept is 4 (0,4)

and the slope is 4/3 which is change in y over change in x

we go up 4 to the right 3

we can rewrite the slope as -4/-3

so we can go down 4 and to the left 3

this would be point (-3,0)

we have 2 points marked, now draw a line throught them

15. Fatima bought a video game that has a

OleMash [197]

Answer:

Step-by-step explanation:

Discount = 15% of 45

$=\frac{15}{100}*45\\\\=\frac{675}{100}=6.75$

= $6.75

Price of the video game = 45 - 6.75 = $38.25

Tax = 7%of 38.25

$=\frac{7}{100}*38.25\\\\=\frac{267.75}{100}=2.6775$

Price paid by Fatima for the video game = 38.25 + 2.68 = $ 40.93

15,000 blue trout were released into the Meherrin River for a scientific study. The function, f(x) = 15,000 (9/8)^x represents t

Ainat [17]

I'm guessing you mean f(x)=15,000(9/8)^x. If this is what you mean, the population would increase by about 12,000 (12030.4870605 to be exact).
Step-by-step explanation:
Starting equation: f(x)=15,000(9/8)^x
You can clean up the 9/8 to be 1.125
Now what you want to do is find the answer to (9/8)^5 which is 1.8020324707
Next multiply 1.8020324707 by 15,000 and you get 27030.4870605
Finally 27,030.4870605 - 15,000 gives you 12030.4870605. Which means that the population increased by about 12,000.

Please mark me brainiest cuz I need one more to level up!! Thank you

Find the indicated probability by using the complementation rule. A percentage distribution is given below for the size of famil

arlik [135]

Answer:

The correct option is c.

Step-by-step explanation:

The percentage probability distribution is:

Size (X) Percentage

2 39.9

3 24.4

4 20.1

5 10.8

6 3.3

7 1.5

Total 100.0

Compute the probability that the size of the family is 4 or more as follows:

P (X ≥ 4) = P (X = 4) + P (X = 5) + P (X = 6) + P (X = 7)

= 0.201 + 0.108 + 0.033 + 0.015

= 0.357

Thus, the probability that the size of the family is 4 or more is 0.357.

The correct option is c.

Assume that the profit generated by a product is given by where x is the number of units sold. If the profit keeps changing at a

scoray [572]

Answer:

21794.495 units/month

Step-by-step explanation:

Some data are missing which i can assume as per requirement of the Question.

Let us consider that profit generated by a product is given by

p(x) =4√x

Also, consider that the profit keeps changing at a rate of $1000 per month.

Now, Using the chain rule we can write

dp/dx=(dp/dt)÷(dx/dt).

So, we can calculate

dp/dx=2x^(-1/2)=2/√x.

As per question we have to find out dx/dt

Since, dx/dt= (dp/dt)/(dp/dx),

so plugging x=1900 we get 1000√1900/2=21794.495 units/month increase in sales.

Which shows the correct order of steps in the formation of coal

just olya [345]

D: Dead plants fall in swamp...

This is the answer because the plants must begin to accumulate in a location, then continue to build tall enough for the rest of the process to continue.

A is incorrect because the plants must die before piling up

B is incorrect because the plants must die and accumulate before compressing

C is incorrect because plants must die before being buried.
