Before rock climbing, Michelle wants to know how
high she will climb. She places a mirror on the
ground and walks backward until she can see the
top of the cliff in the mirror. She drew a sketch of
the situation. What is the height of the cliff?
Answers
Answer:
22 feets
Step-by-step explanation:
From the diagram attached :
We have two similar triangles which can be related proportionally :
Hence ;
Mitchell's height / distance from mirror = cliff height / cliff distance
Michelle's height = 5.5
Michell's distance from mirror = 4
Cliff height = h
Cliff distance from mirror = 16
We have ;
5.5 / 4 = h / 16
Cross multiply :
4 * h = 5.5 * 16
h = 88 / 4
h = 22 feets

Which equation describes the circle
with center (5,-1) and radius 7?
A (x - 5)' + (y +1)* = 7
B (x - 5)* + (y + 1)* = 49
(x + 5) * + (y - 1) = 7
D(x + 5)' + (y - 1)' = 49
Answers
Answer:
B. (x-5)²+(y+1)² = 49
Step-by-step explanation:
An equation of a circle with center (h, k) and radius r is
[tex] \large \boxed{ {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} }[/tex]
We have all given information we need. Our h is 5 - Our k is -1 and our radius is 7
Substitute these values in
[tex] \large{ {(x - 5)}^{2} + {(y - ( - 1))}^{2} = {7}^{2} } \\ \large{ {(x - 5)}^{2} + {(y + 1)}^{2} = {7}^{2} } \\ \large{ {(x - 5)}^{2} + {(y + 1)}^{2} = 49 }[/tex]

A. x^2+3x-4
B. 6x^2-5x+1
Answer:
A: x^2+3x-4
B: 6x^2 -5x +1
Step-by-step explanation:
Alright, so for this, use the FOIL method, by multiplying the terms of each question in this order:
First
Outer
Inner
Last
So with the first question, lets do this:
(x+4)(x-1)
F: x * x = x^2
O: x * -1 = -x
I: x * 4 = 4x
L: 4 * -1 = -4
Then combine the like terms together:
x^2 + -x + 4x -4
A: x^2+3x-4
With the next one, same deal:
(2x-1)(3x-1)
F: 2x * 3x = 6x^2
O: 2x * -1 = -2x
I: 3x * -1 = -3x
L: -1 * -1 = 1
Then combine them up:
6x^2 -2x -3x +1
B: 6x^2 -5x +1
All done!

Find the area inside the 26m square and outside the circle. Use 3.14 for π. A circle is fully inside a square with sides of length 26 meters, such that the circle touches the center of each side of the square.
Answers
Answer:
A(b) = 145,34 m²
Step-by-step explanation:
Area of the square of side l = 26 m A(s) = l² A(s) = (26)²
A(s) = 676 m²
Areaof the circle of radius r = 13 A(c) = π*(r)² A(c) = π*(13)²
A(c) = 169*π m²
Then the area outside the circle and inside the square A(b), is the difference between the area of the square minus the area of the circle, that is:
A(b) = A(s) - A(c) = 676 - 169*π m²
A(b) = 676 - 530,66 m²
A(b) = 145,34 m²
