Answer:
(a).The volume of cube is changing at the rate [tex]450 cm^3/s[/tex]
Step-by-step explanation:
Let x be the side of cube
[tex]\frac{dx}{dt}=6 cm/s[/tex]
We have to find the rate at which volume of cube changing when edge is 5 cm.
We know that
Volume of cube, V=[tex]x^3[/tex]
Differentiate w.r.t t
[tex]\frac{dV}{dt}=3x^2\frac{dx}{dt}[/tex]
Substitute the values
[tex]\frac{dV}{dt}=3(5)^2\times 6[/tex]
[tex]\frac{dV}{dt}=450 cm^3/s[/tex]
Hence, the volume of cube is changing at the rate [tex]450 cm^3/s[/tex]

Choose the correct statement of the rule; then complete the table for missing values. A merchant adds $3.00 to his cost to determine his selling price.
The rule is:
c 1 2 3 4 5
f(c)
Answer:
Selling Price = Cost + $3.00
c 1, 2, 3, 4, 5,
f(c) 4, 5, 6, 7, 8,
The merchant uses Selling Price = Cost + $3.00 to determine the selling price.
What is Addition?Addition is a process of combining two or more numbers.
A merchant adds $3.00 to his cost to determine his selling price.
The cost is denoted by c.
The selling price is given by f(c).
As there is given add in the sentence, it means we have to use the addition rule.
Selling price is the sum of cost plus three
Selling Price = Cost + $3.00
So the table becomes as below
c 1, 2, 3, 4, 5,
f(c) 4, 5, 6, 7, 8,
Hence, the merchant uses Selling Price = Cost + $3.00 to determine the selling price.

The lottery prize is 2m on the 1st week, 5m on the 2nd week. 10m on the 3rd. 13m on
the 4th. 26m on the 5th and 29m on the 6th week.
a) How much is the prize in the 10th week?
b) How much more is the prize worth on the 14th week than the 11th week?
Answer:
a. $125 million
b. $259 million more
Step-by-step explanation:
Looking at the first 3 terms, 5 is 3 more than 2, and 10 is double 5. Knowing that, the pattern is every even term is 3 more than the previous odd, and every odd term is double the previous even. As a result, week 7's prize is $58m (29 * 2), week 8's is $61m (58 + 3), week 9 is $122m (61 * 2), and week 10 (what part a is asking for) is $125m (122 + 3).
Now for part 2. Week 11's prize would be $250m (125 * 2). Week 12's prize would be $253m (250 + 3). Week 13's would be $506 (253 * 2). Week's 14 would be $509 (506 + 3). Now, subtract 250 from 509 to find the difference in prize money, which is $259 million.

Answer:
y = -3x + 6
Step-by-step explanation:
We can first find the y intercept by looking at y when x = 0
y intercept = 6
We can then find the slope by looking at the patterns on the tables.
As we can see, the top row's pattern is +4 every time
The bottom row's pattern is -12
Slope = rise/run
-12/4 = -3
Therefore, the equation for the chart is y = -3x + 6

Car A travels 90 km in the same time car B going 10 km/hr slower travels 60 km. Find the speech of each. List answer for car A first then car B. Do not show units.
Answer:
For
Car A : 30
Car B : 20
Step-by-step explanation:
Let the speed at which Car A travels be x and the time of travel be T. Recall that
speed = distance/time
Hence for Car A.
x = 90/T
T = 90/x
since Car B is B going 10 km/hr slower travels 60 km then
T = 60/(x - 10)
equating both equations
90/x = 60/(x - 10)
cross multiply
90(x - 10) = 60x
90x - 900 = 60x
90x - 60x = 900
30x = 900
Divide both sides by 30
x = 900/30
= 30
This is the speed of Car A : 30km/hr
The speed of Car B = 30 - 10 = 20 km/hr
