<u>Radius Formula</u>
![{[-\sqrt{15}]}^{2} + {[-\sqrt{10}]}^{2} = {r}^{2} → 15 + 10 = {r}^{2} → 25 = {r}^{2}\\ \\ 5 = r](https://tex.z-dn.net/?f=%7B%5B-%5Csqrt%7B15%7D%5D%7D%5E%7B2%7D%20%2B%20%7B%5B-%5Csqrt%7B10%7D%5D%7D%5E%7B2%7D%20%3D%20%7Br%7D%5E%7B2%7D%20%E2%86%92%2015%20%2B%2010%20%3D%20%7Br%7D%5E%7B2%7D%20%E2%86%92%2025%20%3D%20%7Br%7D%5E%7B2%7D%5C%5C%20%5C%5C%205%20%3D%20r)
* Since we are talking about radii, we only want the NON-NEGATIVE root.
In this case, we will not be using the radius in our ratio, according to the trigonometric identity above because we are using the <em>tangent</em><em> </em>ratio:

A logarithm is an exponent. The base of the logarithm is what it is an exponent of. The argument of the logarithm function is the value that you get when you raise the base to the power indicated by the exponent.
Here, the logarithm is 4, so that is the exponent of the base, which is 2. The argument of the log function is 16, so that is the result of raising 2 to the power of 4.
In exponential form, the given expression is equivalent to
2⁴ = 16
Answer:
18
Step-by-step explanation:
12 and 15 are both dividable by 3 and 3 apart so if you subtract 21 by 3 than you get 18
Answer:
T=98W-115W+1840
Step-by-step explanation:
$98 per credit at Westside (W)
$115 per credit at Pinewood (P)
Expression 1 : 98W+115P=T
Expression 2 : W+P=16
Combined: if W=16-P
Total=98W+115(16-W)
T=98W-115W+1840
Answer:
91%
Step-by-step explanation:
The first step is to calculate the increase
= 1635-858
= 777
Therefore the percent increase can be calculated as follows
= 777/858 × 100
= 0.905× 100
= 90.5 %
= 91%
Hence the percentage increase is 91%
