The three integers could be 8, -5, and 1.
What are integers?A number without a decimal or fractional element is known as an integer, which can be both positive and negative, including zero.
Given that, the product of three integers is -40.
Since the product is negative, there should be at least one negative number.
The three numbers can be 8, -5, and 1.
8 × (-5) ×1 = -40
Hence, the three integers could be 8, -5, and 1.

A club plans to spend no more than 85% of the $1,200.00 in its activity budget to buy as many
radio-controlled helicopters as possible. The price of a helicopter is $110.99 plus sales tax of
6%. What is the greatest number of helicopters the club can buy?
Sales tax on helicopter
[tex]\sf\longmapsto 0.6(110.99)=6.65[/tex]
Cost of one helicopter
[tex]\sf\longmapsto 110.99+6.65=117.64[/tex]
Now
85% of 1200.00:-[tex]\sf\longmapsto 0.85(1200)= 1020[/tex]
Total helicopters:-
[tex]\sf\longmapsto 1020/117.64\approx 9[/tex]

Answer:
y=0.5x-4.5
Step-by-step explanation:
y=mx+b
Use the information provided to find b
0=0.5(4)+b
-2=b
Therefore, the equation goes down to...
y= 0.5x-2
Step-by-step explanation:
using the formula
m = y -y1/ x - x1
0.5 = y -0/x-4 (0.5 = 1/2)
1/2 = y/x -4
2y = x -4
divide both sides by 2
y = 1/2 ( x -4)
y = 1/2x - 2
y -1/2x = -2

(7 pts) A school has 400 feet of fencing to build a set of 3 athletic fields as shown below. What dimensions
should they use to build the largest possible athletic complex? Include appropriate units with your answer.
х
Answer:
Step-by-step explanation:
the side lengths are (400 - 4x)/2 = 200 - 2x
A = x(200 - 2x)
A = 200x - 2x²
Maximum area will occur when the derivative is set to zero.
dA/dx = 200 - 4x
0 = 200 - 4x
x = 200/4 = 50 ft
each field will be 50 x 33⅓ ft.
total area will be 5000 ft²

Step-by-step explanation:
to check plug the numbers to the equation and you will that it is right
Answer:
f(x) = 8x + 3
Explanation:
I knew f(x) = mx +b is the formula for a linear equation and that when x = 0,
f(x) = b
So, when x = 0 in the table, f(x) = 3 and therefore b = 3
Now we can plug in f(x) = 11 and x =1 into f(x) = mx+b along with our b value
11 = m(1) + 3
solving for m we get m = 8 which finishes our unknowns
f(x) = mx + b
f(x) = 8x + 3
(3,-3), m=-2

Answer:
dy/dx = (2 -x)/40.005Step-by-step explanation:
(a) Solving the x-equation for u gives ...
u = (x -1)/4
Differentiating both equations with respect to u, we have ...
dy/du = 1 -4u
dx/du = 4
Then dy/dx is ...
dy/dx = (dy/du)/(dx/du) = (1 -4u)/4
Substituting for u gives ...
dy/dx = (1 -4(x -1)/4)/4
dy/dx = (2 -x)/4
__
(b) The approximate change in y is ...
∆y ≈ (dy/dx)(∆x)
For ∆x = 2.98 -3.00 = -0.02, and x=3, the approximate change is ...
∆y ≈ (2 -3)/4(-0.02)
∆y ≈ 0.005
