In algebra, why do you think that you are given many problems to solve that aren't really "real life" problems? For example, "Tw

Answer:

You can't understand the upper most level in math unless you understand the lower levels. With that said, the construction of the roads we drive on, the planes we fly in, the houses we live in, the pots, pans, cooking utensils, and eating utensils we cook and eat with, etc. all are dependent on a strong knowledge and foundation of math.

Step-by-step explanation:

Hope you have a great day ;-)

Find the standard form of the equation of the parabola with a focus at (0, -2) and a directrix at y = 2.
anyanavicka [17]
Hello,
The parabola having like focus (0,p/2) and as directrix y=-p/2 has as equation x²=2py

Here -p/2=2==>p=-4

x²=-8y is the equation.

In 2004, a magazine's circulation was about 1,000,000 readers. In 2014, the magazine had about 2,000,000 readers. Write a linear
Sever21 [200]

Answer:

m= \frac{r_2 -r_1}{t_2 -t_1}= \frac{2000000-1000000}{14-4}=100000

And then we can use for example the first point (t_1, r_1) = (4, 1000000) to find the intercept:

1000000= 100000*4 + b

b=600000

So then the linear model for this case should be:

r = 100000 t + 600000

Step-by-step explanation:

For this case we want to find a linear model given by:

r =mt+b

Where r = represent the number of readers , t= years after 2000

m = the slope for the model and b the intercept

For this case we can define the following points from the data given:

(t_1, r_1) = (4, 1000000) 4 years after 2000

(t_2, r_2) = (14, 2000000) 14 years after 2000

We can find the slope with the following formula:

m= \frac{r_2 -r_1}{t_2 -t_1}= \frac{2000000-1000000}{14-4}=100000

And then we can use for example the first point (t_1, r_1) = (4, 1000000) to find the intercept:

1000000= 100000*4 + b

b=600000

So then the linear model for this case should be:

r = 100000 t + 600000
