Answer:
- ornament area = 379.8 cm²
- paint needed: 114 bottles
Step-by-step explanation:
The surface area of one cone with slant height s and radius r is ...
SA = πr² +πrs = πr(r+s)
For the cone that is half an ornament, the surface area is ...
SA = (3.14)(4.2 cm)(4.2 cm + 10.2 cm) = 189.9072 cm²
The area of one ornament is the area of two cones:
one ornament area = 2×189.9072 cm² ≈ 379.8 cm²
60 ornaments will be 120 cones, so will have a total surface area of ...
total area = 120(189.9072 cm²) = 22,788.864 cm²
__
If one bottle of paint will cover 201 cm², then the number of bottles of paint required is ...
(22788.864 cm²)/(201 cm²/bottle) ≈ 113.4 bottles
Answer:
y = -3x + 17
Step-by-step explanation:
In this question, you have to put the given equation into slope intercept form.
Slope-intercept form: y = mx + b
Solve:
y - 2= -3(x - 5)
Use the distributive property to distribute the -3 to the variables inside the parenthesis.
y - 2 = -3x + 15
Add 2 to both sides to get "y" by itself.
y = -3x + 17
The slope intercept form of the line would be y = -3x + 17
Answer:
first term (a)= 2
second term (b) = -8
common ratio (r) = -8/2 = -4
15th term = ar^ (n-1)
= 2* (-4)^ 14 =536870912
