2.45+3.6+4.5=10.55
I don't agree with Amy because 2.45+3.6+4.5=10.55, which is greater than 10, not less than 10.
Answer:
1057.89 feet
Step-by-step explanation:
Trig time! Start with a diagram and listing out your trig functions, either mentally or on paper. SOH CAH TOA
The best trig function for this problem is likely tan:
tan84.6 = height / 100
100 * tan 84.6 = height
height = 1057.89 feet
Answer:
The numbers are -21 and 21
Step-by-step explanation:
Let
x ----> one number
y ----> another number
S----> the sum of their squares
we know that
----> equation A
----> equation B
substitute equation A in equation B
This is the equation of a vertical parabola open upward
The vertex is a minimum
Find the coordinates of the vertex
Using a graphing tool
The vertex is the point (21,882) ----> see the attached figure
we have
x=21
<em>Find the value of y</em>
therefore
The numbers are -21 and 21
The answer is the first one
Answer:
(3, - 4)
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), hence
(- 3, 4 ) → (3, - 4 )
