Answer:
Square root of 87.35 will be plotted between 9 and 10 as shown below.
Step-by-step explanation:
We are given that, 'The number line is numbered in tenths'
Also, the square root of 87.35 is given by,
That is, we have to plot the point 9.4 on the number line numbered in tenths.
As, 9.4 will lie between the points 9 and 10.
Thus, we get that square root of 87.35 will be plotted between 9 and 10 as shown below.

Answer:
angle of elevation will be
Step-by-step explanation:
Given,
height of tower = 150 ft
height of tower = 1200 ft
So, total height of peak of tower = 1200 + 150
= 1350 ft
distance of user from cell tower = 5 miles
= 5 x 5280 feet
= 26,400 feet
Since the height of user from sea level = 400 ft
so, height of peak of tower with respect to user = 1350 - 400 ft
= 950 ft
If the angle of depression is assumed as , then we can write
So, the angle of elevation will be
Let
x-------> the length side of the poster
y-------> the width side of the poster
we know that
Area of the poster is equal to
-------> equation
Area of the printed area is equal to
----> equation
substitute equation in equation
using a graph tool
Find the vertex of the graph
The vertex of the graph is the point that represent the value of x for the largest printed area
see the attached figure
the vertex is the point
the largest printed area is
find the value of y
therefore
the answer is
The dimensions of the poster are
