Take a look at the diagram below.
This problem looks like a great candidate for using the Law of Cosines.
If you know two sides, you can find the third side from the angle opposite or vice versa. Should the sides be a, b, and c, and their opp. angles A, B, and C...
a² + b² - 2ab(cosC) = c²
Let's plug in what we know...a = 55, b = 25, and m<C = 25".
55² + 25² - 2(55)(25)(cos(25")) = c²
One thing to note is that our angle measure is in <em />seconds. Unless you're using Google's built in calculator, you'll wind up having to convert to degrees. 60 seconds in a minute, 60 minutes in a degree...blahblahblah.
Anyways, cos(25") comes out to be practically 1. (0.99999993)
Let's get evaluating.
3025 + 625 - 2750(1) = c²
3025 + 625 - 2750 = c²
900 = c²
30 = cThe tree is

Answer:
c)Step 3
Step-by-step explanation:
We are given that an inequality
We have to find the incorrect step in which Mia makes a mistake.
Step 1:
Reason: Given
Step 2:
Reason: Subtraction property of inequality
Step 3:
Reason: Subtraction property of inequality
Step 4:
Reason: division property of inequality
Answer: C)Step 3
The complete question in the attached figure
we have that
f(x)=x²-5x+6
and <span>g(x) has a vertex at (2,4) and the parabola opens downwards
using a graph tool
see the attached figure
</span><span> statements
a) </span><span>The y-intercept of function f is less than the y-intercept of function g
this is not correct, because the </span>y-intercept of function f is greater than the y-intercept of function g
b) <span>The minimum of function f is at (-5,6)
this is not correct, because the minimum of function f is at (2.5,-0.25)
c)</span><span>The y-intercept of function f is greater than the y-intercept of function g
this is correct
d) </span><span>The minimum of function g is at (2,4)
this is not correct because the maximum of function g is </span>(2,4)
the answer is the option
The y-intercept of function f is greater than the y-intercept of function g
