Answers
so remember
a^2+b^2=c^2
a and b are the legs
c=hypotonuse so
a=24
b=45
subsitute
24^2+45^2=c^2
576+2025=c^2
2601=c^2
square root both sides
51=c
the answer is A. 51 ft
2. just subsitute and solve for ones that are not equal (hypotonuse is greater than either legs)
A. 3^2+4^2=5^2
9+16=25
25=25
correrct
B. 6,8,10
this is a multiplule of the 3,4,5 previoius so this works as well
C.16^2+63^2+65^2
256+3969=4225
4225=4225
correct
D. 8^2+9^2=10^2
64+81=100
145=100
false
the answer is D
ANSWERS:
1. A, 51 ft
2. D, 8,9,10
To solve the problem use the Pythagorean Theorem. There are 3 parts to the Pythagorean Theorem. A (squared)+ B (squared) = C(squared). To "square" a number mutiply to itself. A=24
B=45, C is the Hypotenuse, you want to find out C. A is 24, a leg. B is 45, a leg. A squared is 24*24, 576 feet. B squared is 45*45, 2025 feet. To find C (the hypotenuse), add 576+2025 which is 2601 feet. The answer is **2601 feet**. Sometimes they will only give you 1 leg and the hypotenuse and want you to find the 2nd leg answer.
An example is if they asked " a right triangle has a 24 ft leg and hypotenuse is 2,601 ft. What is the length of the other leg? Still use Pythagorean Theorem. A is 24 ft,
you are looking for B,
you know that C is 2601 ft. So it is (24*24) +X squared=2601 ft. Then
2601-576. The answer is 2025, press square root button and it is 45 ft

Answer:
vertex = (9, - 1 )
Step-by-step explanation:
Given a quadratic in standard form, y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
y = x² - 18x + 80 ← is in standard form
with a = 1 and b = - 18, thus
= -
= 9
Substitute x = 9 into the function for corresponding value of y
y = 9² - 18(9) + 80 = 81 - 162 + 80 = - 1
Vertex = (9, - 1 )
