Answer:
c = 31.5
Step-by-step explanation:
Given c varies directly as then the equation relating them is
c = k ← k is the constant of variation
To find k use the condition c = 14 when d = 64, then
14 = k × = 8k ( divide both sides by 8 )
1.75 = k
c = 1.75 ← equation of variation
When d = 324 , then
c = 1.75 × = 1.75 × 18 = 31.5
Answer:
P = 6x³ + 12x² - 18x + 8
Step-by-step explanation:
Given that:
Length = 3x3+4x2−6x
Width = 2x2−3x+4
The length of fencing needed will be :
Perimeter of rectangle (P) = 2( Length + Width)
P = 2[ (3x3+4x2−6x) + (2x2−3x+4)]
P = 2 (3x³+ (4x² + 2x²) + (-6x - 3x) + 4)
P = 2(3x³ + 6x² - 9x + 4)
P = 6x³ + 12x² - 18x + 8
I'm not I understand. The range is the highest value minus the lowest value, which on the graph is 10-4=6.
Answer:
2y-1
Step-by-step explanation:
1/2(4y-2)=2y-1
5.5-3b = 2b-6.25
5.5+6.25 = 2b+3b
11.75 = 5b
11.75/5 = 5b/5
2.35 = b
