Once Isabel rented the warehouse space, she decided to post ads on several social media sites to advertise her online bookstore.

Let m represent the number of months the ads have been posted. Isabel finds that the function below describes the number of books sold as a function of the number of months her ads have been posted. f(x) = 1000(∛x) + 1000
How many books were sold after 8 months? (3 points)



Graph the function. (10 points)

1. Number of books that were sold after 8 months:
f(8)=1000 \sqrt[3]{8}+1000
f(8)=1000 * 2 + 100 = 2000+1000=3000
Answer: 3000 books
2. Graph of the function is in attachment.

See the picture attached to better understand the problem

we know that
in the right triangle ABC
sin 70°=opposite side angle 70°/hypotenuse


in this problem
opposite side angle 70°=AB
hypotenuse=AC----> 32 ft
sin 70°=AB/32------> AB=32*sin 70°-----> AB=30.07 ----> AB=30.1 ft

What is an equation of the line that is perpendicular to −x+2y=4 and passes through the point (−2, 1) ?
Elza [17]

Answer:

y=-2x-3

Step-by-step explanation:

Since our equation is in standard form Ax+By=C we must first manipulate the equation so that we have it in the slope-intercept form such that y=mx+b.  Therefore:

-x+2y=4\\2y=x+4\\\\y=\frac{x+4}{2}\\\\y=\frac{1}{2}x+2

Therefore, our slope is 1/2 and our y-intercept is 2.  Now in order to determine a perpendicular line to the one stated above we must then get the negative inverse of our slope meaning \frac{1}{2}=-2 (negative reciprocal).  Now we must use the point slope formula:

y=m(x-x_1)+y_1

Where m is the slope, x1 is -2 and y1 is 1 (because of the ordered pair given). And so:

y=-2(x-(-2))+1\\\\y=-2(x+2)+1\\\\y=-2x-4+1\\\\y=-2x-3

Therefore, the line that is perpendicular to -x+2y=4 is y=-2x-3.

Anvisha [2.4K]
For a question like this, all you have to do is remember that a percentage is simply a fraction expressed as a decimal. So, all we have to do is:
\frac{187}{550}, and then multiply our decimal answer by 100 to get the percentage:
\frac{187}{550} = 0.34
0.34 x 100 = 34
Therefore 34% of the students walk to school.
I hope this helped and remember to please try and understand the maths that got the answer, not just writing the answer down :))

In a basketball game 15 of 20 foul shots that Michelle attempted were successful. What percent of her shots were not successful?
mestny [16]
<u>Work 1:</u>
   Successful Percent:

     15 divided by 20 equals .75
     .75 times 100 is equal to 75
     75%
   Not successful Percent:
     
100% minus 75% equals 25%
     <em>25%</em>
<u>Work 2:</u><u />
     20 minus 15 equals 5
     5 divided by 20 is equal to .25
     .25 times 100 is equal to 25
     <em>25%</em>
