f (7)=19
Hope this helps :)
Answer:
D
Step-by-step explanation:
Alice and Amy are standing on the 2 opposite endpoints of the diagonal of a rectangle. (Well, this is the best way to think of the situation geometrically.)
The shortest distance is certainly when Amy walks straight through the diagonal. So, we need to find the length of the diagonal.
A diagonal divides a rectangle into 2 congruent (identical) right triangles. The sides of any of these 2 triangles are 100 ft and 60 ft, thus we can find the diagonal by the Pythagorean theorem:

,
so,

(ft).
Answer: 117 ft
The length and width of the computer monitor is 23.36 inches
and 13.14 inches.
According to the given statement
we have given that
The length of diagonal of rectangular monitor = 27 inches
The length to width ratio is 16:9
So , Let the Length of monitor = 16x
and The Width of monitor = 9x
And we have to find the length and width of the computer monitor.
So, For this purpose,
From Pythagoras theorem
(Diagonal)² = Length² + width²
Put the values in it and then
27² = (16x)² + (9x)²
729 = 256x² + 81x²
After solving we get
337x² = 729
So, x² = 2.16
∴ x = = 1.46 inches
So, The length = 16x = 23.36 inches
And The width = 9x = 13.14 inches.
Hence, The length and width of the computer monitor is 23.36 inches
and 13.14 inches.
