Answer:
17.7 cm^2
Step-by-step explanation:
The formula for finding the hypotenuse using the pythagorean theorem is:
or, it can also be 
. But I will be using the first formula.
We first plug in the "legs" to the equation:
Now, you find the square root of 314.
And finally, just round to the nearest tenths place!
Answer:
B 4 Dimes
Step-by-step explanation:
4 x 10 = 40 cents
18 x 25 == 4.50 Dollars
40 + 4.5 = 4.90
The tangent line DC is perpendicular to the radius of the park
The length of AC is 245 feet
<h3>How to determine the distance AC?</h3>
To calculate the distance AC, we start by calculating the length of AB using:
DC^2 = (BC + AB) * BC
So, we have:
105^2 = (45 + AB) * 45
Evaluate the exponent
11025 = (45 + AB) * 45
Divide both sides by 45
245 = 45 + AB
Rewrite as:
AB + 45 = 245
From the figure, we have:
AC = AB + 45
Substitute AB + 45 = 245
AC = 245
Hence, the length of AC is 245 feet

Answer:
(5,10)
Step-by-step explanation:
So we have the system of equations:
To solve, we can use substitution.
Substitute the first equation into the second:
Combine like terms:
Subtract 5:
Divide by 4:
Now, substitute this into the first equation:
Add:
So, our answer is (5,10)
And we are done :)
