The car they will be using uses 6.3 litre/100km and runs on 50 ppm
diesel which will cost them R17.82/litre. Determine their fuel cost in
cents per kilometre.
(5)
Answers
Answer:
[tex]Cost = 112.266[/tex] cent/km
Step-by-step explanation:
Given
[tex]Unit\ cost = R17.82/litre[/tex]
[tex]Rate = 6.3litre/100km[/tex]
Required
The fuel cost in [tex]cent\ per\ km[/tex]
This is calculated using:
[tex]Cost = Unit\ cost * Rate[/tex]
[tex]Cost = R17.82/litre * 6.3litre/100km[/tex]
[tex]Cost = R17.82 * 6.3/100km[/tex]
[tex]Cost = R1.12266/km[/tex]
Multiply by [tex]100[/tex] to get the cost in cents
[tex]Cost = 1.12266 * 100[/tex] cent/km
[tex]Cost = 112.266[/tex] cent/km

What is the are in square feet of the trapezoid
Answers
Answer:
A = 94.6ft^2
Step-by-step explanation:
In order to be able to find the area of a trapezoid or any quadrilateral shape we need to use the equation:
A= a+b/2h
As we know we have the number base 7.7ft, base 14.3ft, and height of 8.6ft so then we take these numbers :
7.7 + 14.3/2 x 8.6 = 94.6

Area is calculated by multiplying the length of a shape by its width. In this case, we could work out the area of this rectangle even if it wasn't on squared paper, just by working out 5cm x 5cm = 25cm² (the shape is not drawn to scale). Hope this helps

B. [tex]C*e^{2/3} \sqrt{(3x^{2} -1)^{3}}[/tex]
C. None of these
Answers
This ODE is separable as
1/(6x) dy/dx = y √(3x ² - 1)
→ dy / y = 6x √(3x ² - 1) dx
Integrate both sides:
∫ dy / y = ∫ 6x √(3x ² - 1) dx
The left side is trivial. For the right side, substitute u = 3x ² - 1 and du = 6x dx :
∫ dy / y = ∫ √u du
ln|y | = u ³′² + C
(that is, u is raised to the 3/2 power)
ln|y | = (3x ² - 1)³′² + C
Solve for y by taking the exponential of both sides:
exp(ln|y |) = exp((3x ² - 1)³′² + C )
y = exp((3x ² - 1)³′²) × exp(C )
y = C exp((3x ² - 1)³′²)
which can be written as
y = C exp(√((3x ² - 1)³))
which makes the answer none of these; this solution can't be expressed as either option given in A or B.

Answer
65 feet long
Step-by-step explanation:
15x5 is 65
Answer:
Step-by-step explanation:
5 feet ÷ 8 = 5/8 of a foot for each rod.
(In inches that would be 5/8 × 12 inches = (5 × 12)/8 inches = 60/8 inches = 15/2 inches = 7 1/2 inches.)
13 rods would be 13 × 5/8 feet = (13 × 5)/8 feet = 65/8 feet = 8 1/8 feet

This table models function m.
Answers
Answer:
A: The y-intercept of function m is less than that of function n.
Step-by-step explanation:
From the table, we see that when x = 0, m(x) = -6.
This means that the y-intercept of function m is -6.
For the function "n", we are told it passes through (-1, 0) and (0, 2)
We see that at the second coordinate, at x = 0, y = 2.
This means that the y-intercept of the n function is at 2.
Therefore,we conclude that the y-intercept of function m is less than that of function n.
