• ### Tips for Grade 11 Student?

I'm studying to become a neurologist, and I'm just wondering what courses to take and what to do in high school to make my college application to stand out in the future?

Solve this equation: √-2 + 8x = √-44 + 2x

-2 and 8x are under the √

-44 and 2x are under the √

The time in years, T, for one complete orbit of a planet around a star can be calculated from the equation:

T=√ Kr3

The average radius, in kilometres, of the planet’s orbit is r, and K is a constant that changes depending on the mass of the star.

(1) Rearrange the equation to isolate K.

Then calculate for K for Earth’s solar system knowing that Earth takes one year to go around the sun and that the radius of Earth’s orbit is 1.49 x 10^8 km from the sun

(2) Calculate how many Earth years it takes Neptune to complete an orbit. Neptune’s average orbital radius is 4.5 x 10^9 km.

• ### Solving Quadratic Inequalities in One Variable?

800 people will attend a concert if tickets cost \$20 each. Attendance will decrease by 30 people for each \$1 increase in the price. The concert promoters need to make a minimum of \$12 800.

What quadratic inequality represents this situation?

What is the range of ticket prices the concert promoters can charge and still make at least the minimum amount of money desired?

• ### Solving Systems of Equations Algebraically?

A canopy tour company designs zip line rides through forest and jungle environments. One particular zip line takes the passenger through a waterfall, the maximum height of which is 167 ft. The dimensions of both the zip line and the waterfall are shown in the image below.

Model this scenario with a system of equations.

Hint, use:

y = mx + b

and

y = a(x -p)2 + q

• ### Solving Quadratic Systems Graphically?

Solve the following systems by graphing on your calculator or a website and give the solution

Then show how the solutions would be verified, by using the LEFT SIDE = RIGHT SIDE method

y=2x^2 + 7x − 5

y=−1/3^2 − 2x + 9

• ### Help with Geometric Sequence?

How does a rolling snowball reflect the nature of compound interest?

• ### Geometric Sequence?

The geometric sequence shown in the pyramid is 6, 36, 216, 1296, ¼.

Consider this geometric sequence and the 13th term. Is this pyramid scheme sustainable?
