Answer:
Step-by-step explanation:
Let
x------> the volume of the small swimming pool
y------> the volume of the large swimming pool
z-----> the scale factor
we know that
The volume of the small swimming pool is equal to the scale factor elevated to the cube multiplied by the volume of the large swimming pool
so
In this problem we have
substitute

A.
(0,00
(2.6,7.9)
(4.8,12.4)
(9.7,15.1)
b.
well, the points don't look like they are on the line but they actually are (plot twist)
so
since (0,0) is on th egarph
0=a(0)²+b(0)+c
0=c
so
f(x)=ax²+bx+0 or
f(x)=ax²+bx
find a and b
sub points
(2.6,7.9)
7.9=a(2.6)²+b(2.6)
7.9=6.76a+2.6b
(4.8,12.4)
12.4=a(4.8)²+b(4.8)
12.4=23.04a+4.8b
use those 2 equations
7.9=6.76a+2.6b
12.4=23.04a+4.8b
eliminate b
multiply first equation by -4.8 and 2nd by 2.6 and add them
-37.92=-32.448a-12.48b
32.24=59.904a-12.48b +
-5.68=27.456a+0b
-5.68=27.456a
divide both sides by 27.456
(-5.68/27.456)=a
find b
12.4=23.04a+4.8b
12.4=(-130.8672/27.456)+4.8b
12.4+(130.8672/27.456)=4.8b
(12.4+(130.8672/27.456))/4.8=b
da equation is
c. the roots are found with your calculator
the roots are at x=0 and x=17.287323943662
so very close to the target but not exactly on it
if the target has a radius of 0.287323943662 or more then it will hit the target

Answer:
Therefore,
Step-by-step explanation:
Given:
0° < θ < 360°
tan θ = 3.5134
To Find:
θ in degrees = ?
Solution:
0° < θ < 360° .............Given
Means ' θ ' is between 0° and 360°
.............Given
Therefore,
Also,
So ' θ ' will have Two values for tan θ =3.5134
Therefore,
