Answer:
a =
Step-by-step explanation:
To find the value of a, find the Slope of both the equations.
For lines to be perpendicular to each other
For line 1:
2x + 3y − 6 = 0 represent the line in y=mx +c form
3y = -2x + 6
y = +
y = + 2
=
For line 2:
ax - 3y = 5
ax = 5 + 3y
ax - 5 = 3y
y =
=
Apply the condition of perpendicularity:
*
= - 1
a =
Answer:
!. Scale factor = 5
2. Scale factor =
Step-by-step explanation:
scale =
1. To increase the numbers, let the scale factor be = 5. So that;
0.05 x 5 = 0.25
x 5 = 0.5 x 5 = 2.50
7 x 5 = 35.00
13 x 5 = 65.00
25 x 5 = 125.00
102 x 5 = 510.00
2. To decrease the numbers, let the scale factor be . So that;
0.05 x = 0.01
x
= 0.5 x
= 0.10
7 x = 1.40
13 x = 2.60
25 x = 5.00
102 x = 20.40
Formula for volue of cylinder is area time height. Lets find area
A=
diameter=2r
8=2r
r=4
Now substitute r to
A=
Now we have formula
V=
- its the result, so B
A=
diameter=2r
8=2r
r=4
Now substitute r to
A=
Now we have formula
V=
