You can run 5 miles in 25 minutes. At this rate, how many miles can you run in 3 hours
kotegsom [21]
Well, if you run 5 miles in 25 minute you run a mile every 5 minutes. So, there is 190 minutes in 3 hours. So we would need to divide 190 by 5 which is 38. So, the person could run 38 miles in 3 hours.

Use the quadratic formula to solve the equation.–x2 + 5x = 3
Karo-lina-s [1.5K]

Given the equation - x² + 5x = 3, which can be rewritten as:

- x² + 5x - 3 = 0

where a = -1, b = 5 and c = -3.

Quadratic formula:

\frac{-b\text{ }\pm\text{ }\sqrt[]{b^2\text{ - 4ac}}}{2a}

Now, we just replace the values of a, b and c on the equation above.

\frac{-5\text{ }\pm\text{ }\sqrt[]{5^2\text{ - 4(-1)(3)}}}{2(-1)}

=

\frac{5}{2}\text{ }\pm\text{ }\frac{\sqrt[]{13}}{2}

For a computer science degree, if you have a bachelor's degree your projected yearly income is $68,103 and if you have a master'
MAVERICK [17]

Answer:

566,880

Step-by-step explanation:

First you have to understand what the problem is asking you. It wants you to find the difference between working for 40 years with a master's degree and 40 years with a bachelor's degree.

Next you need to do the math. You can use a calculator since these are pretty large numbers. Enter in the following to find how much you make working 40 years with a bachelor's degree: 68,103 * 40 Once you have calculated that, you should get 2,724,120. Now you need to find how much you earn working 40 years with a master's degree. Enter the following: 82,275 * 40 You should get 3,291,000.

Finally you need to find the difference. Type into your calculator the following: 3,291,000 - 2,724,120 You should end up with 566,880.

Hope this helps!

2. State two (2) values of θ (theta) to the nearest degree for<br> sin θ = − 0. 966
emmasim [6.3K]

Using equivalent angles, the solutions to the equation are given as follows:

\theta = 255^\circ, \theta = 285^\circ

<h3>What are equivalent angles?</h3>

Each angle on the second, third and fourth quadrants will have an equivalent on the first quadrant.

In this problem, the equation is:

\sin{\theta} = -0.966

Applying the inverse relation:

\theta = \arcsin{-0.966} = 255^\circ

Which is on the third quadrant. The equivalent angle on the fourth quadrant is given as follows:

270^\circ + (270^\circ - 255^\circ) = 285^\circ
