Hidden right triangle
28 feet tall (1 leg)
the piece that fell over is the hypotonuse
last leg is what we need to find
81-28=53
a²+b²=c²
a and b are legs and c is the hypotonuse
given
on leg is 28 and the hypotonuse is 53
th othe leg is b
28²+b²=53²
784+b²=2809
minus 784 from both sides
b²=2025
sqrt both sides
b=45
answer is 45ft
Answer: The Vertex is at (-1,25)
Axis of symmetry X=-1

Right x intercept (4,0)
I’m not to sure about the set of all real numbers or the range but i hope this helped
Step-by-step explanation:
Graph on Desmos
The question is an illustration of solving equations using estimates.
The student's strategy makes sense because he uses estimation to solve the given equation
The correct sequence of equation is as follows:
We have:

Add 0 to the equation

Express 0 as 1 - 1


Add another 0

Express 0 as 3 - 3


Rewrite as:

Solve

Step-by-step explanation:
Hello from MrBillDoesMath!
Answer:
The second choice, [1,2]
Discussion:
The key to this question is that we are looking for "local maximum". In the graph a local maximum, think "camel hump", occurs in the interval [1,2] -- but the global maximums, if there is one, appears to occur in x > 3 and x < -1
Thank you,
