Answer:
1
Step-by-step explanation
Since you are given two points you can calculate the slope by use the formula Y1-Y2/X1-X2.
In this case:
Y1 = 5
Y2 = 7
X1 = 7
X2 = 9
(5-7)/(7-9) = -2/-2 = 1
Answer:
39.30 
Step-by-step explanation:
The area of the top surface of the wedge is the same as the area of a sector.
Area of a sector = (θ/
)

where: θ is the central angle, and r is the radius.
Given that: central angle =
, radius = 10 centimetre.
Area of the top surface = Area of a sector = (θ/
)

=

x 100
= 39.2857
= 39.30 
The area of the top surface of the wedge is 39.30

Answer:
7.9 * 10 ^-6
Step-by-step explanation:
Move the decimal 6 places to the left so there is one number before the decimal
0.0000079
7.9
The exponent is -6 ( negative because we moved it to the left)
7.9 * 10 ^-6
