Answer:
z = 5
Step-by-step explanation:
m = ∆y/∆x = y₂-y₁/x₂-x₁
0 = y₂-y₁/x₂-x₁ = 5 - z / -7 - 9 = 5 - z / -16 →
5 - z / -16 = 0 → 5 - z / -16 × -16 = 0 × -16 → 5 - z = 0 →
5 - z - 5 = 0 - 5 → -z = -5 → z = 5
The bead is in a cylindrical shape and the formula for solving the volume of a cylinder is V=pi*r²*h where "r" is the radius, "h" for the height.
We have given values such as:
r=diameter/2 = 2/2 = 1mm
h= 8mm
Solving for the volume, we have:
V=3.14*1²*8
V=24.12 mm²
A.
Find the dimensions of the original painting.
Since the scale is 1 in : 40 cm
2 in ( 40 cm / 1 in) = 80 cm
1.5 in ( 40 cm / 1 in) = 60 cm
80 cm by 60 cm
B.
Find the area of the original painting.
<span>A = 80
cm x 60 cm = 4800 sq cm</span>
C.
Since 1 inch is 2.54 cm, find the dimensions of the original painting in
inches.
80 cm ( 1 in / 2.54 cm) = 31.5 in
60 cm ( 1 in / 2.54 cm) = 23.6 in
D,
Find the area of the original painting in square inches.
A = 31.5 in x 23.6 in = 743.4 sq in

X=14
Y=15
Im assuming you want to find out what x and y are
Hey there!
This can be written as

This is in form of

, it can be expanded as
=> (n-7)(n+7)=0
=> n -7 = 0 or n + 7 = 0
=> n = 7 or n = -7
So option 7 , -7 are correct.
Hope this is clear :)
Have a good day:)
