5. To get to the library from his house, Robert biked 6 kilometers due east and then

AURORKA [14]

Answer:

24 kilometers.

Step-by-step explanation:

The shortest path between two points is a straight segment that connects the two points.

Refer to the diagram attached. The 6-km segment and the 8-km segment are normal to each other. Together with the segment that joins the library and the house, the three segments now form a right triangle.

The two shorter segments are the two legs, and
The longer segment that joins the library and the house is the hypotenuse.

The length of the hypotenuse can be found with the Pythagorean Theorem.

$\begin{aligned}\text{Hypotenuse} &= \sqrt{(\text{Leg 1})^{2} + (\text{Leg 2})^{2}}\\&= \sqrt{6^{2} + 8^{2}}\\&= \sqrt{36 + 64} \\&= \sqrt{100}\\&= \rm 10\;km\end{aligned}$ .

The length of the round-trip will equal to the sum of the length of the three segments: $\rm 6\;km + 8\;km + 10\;km = 24\;km$ .

Gracie bought a cd for $810 that earns a 2.9 APR and is compounded quarterly. The CD matures in 5 years. How much will this CD b

enyata [817]

Answer:

The amount that this CD will be worth at maturity would be $935.90. The right answer is B.

Step-by-step explanation:

In order to calculate How much will this CD be worth at maturity we would have to use and calculate the formula of future value as follows:

Future Value=Present value×(1+i/n)∧nt

Future Value=$810×(1+2.9%/4)∧(4×5)

Future Value=$935.90

The amount that this CD will be worth at maturity would be $935.90

Evaluate the expression when r = 8.2 and s = –3.7.

kiruha [24]

When you plug in the numbers for the integers, you get
8.2-2(-3.7)
If you multiply -2 and -3.7, you get 7.4 because the negatives cancel each other out.
If you then add 8.2, you get 15.6. So the answer is D.
Hope it Helps! :)
