The function in standard form is:
g(x) = 3x^3 - 39x - 36
How to write the function in standard form?
Here we want to find the function g(x) = 3(x+1)(x+3)(x-4) in standard form, we just want to expand the function.
We will get:
g(x) = 3*(x + 1)*(x + 3)*(x - 4)
g(x) = 3*(x + 1)*(x^2 + 3*x - 4*x + 3*-4)
g(x) = 3*(x + 1)*(x^2 - 1*x - 12)
g(x) = 3*(x^3 + x^2 - x^2 - x - 12x - 12)
g(x) = 3*(x^3 -13x - 12)
g(x) = 3x^3 - 39x - 36

In a triangle, one acute angle is 33 degree. The adjacent side of angle 33 degree is 8 and opposite side is x. The largest side of the triangle is 15."/> find the value of x to the nearest tenth
The value of x, to the nearest tenth, is approximately 4.96. The steps involved using the tangent ratio and solving for the unknown side in a right triangle.
In a triangle, the angle opposite to the side x as angle A, and the side opposite to the angle 33° as side B, and the largest side as side C. So we have:
Angle A = 90° - 33° = 57° (since the sum of angles in a triangle is 180°)
Side B = 8
Side C = 15
Side x = ?
Write the formula for the tangent ratio in terms of the sides of the triangle. For angle A, we have:
tangent(A) = opposite/adjacent
Substitute the known values into the formula and solve for the unknown side. Substituting the values we have, we get
tangent(33°) = x/8
Multiplying both sides by 8, we get:
x = 8 * tangent(33°)
Use a calculator to find the value of the tangent of 33 degrees. We get:
tangent(33°) ≈ 0.6494
Substitute the value of the tangent into the formula we obtained in step 3 and solve for x. We get
x ≈ 8 * 0.6494
x ≈ 5.1952
Round the answer to the nearest tenth, since the question asks for the value of x to the nearest tenth. We get
x ≈ 4.96
Therefore, the value of x, to the nearest tenth, is approximately 4.96.

How many solutions are there to the equation x1 + x2 + x3 + x4 + x5 = 21, where xi , i = 1, 2, 3, 4, 5, is a nonnegative integer such that a) x1 ≥ 1? b) xi ≥ 2 for i = 1, 2, 3, 4, 5? c) 0 ≤ x1 ≤ 10? d) 0 ≤ x1 ≤ 3, 1 ≤ x2 < 4, and x3 ≥ 15?
The combination formula helps to determine the number of non-negative solutions of equation
x₁ + x₂ + x₃ + x₄ + x₅ = 21 in different cases.
a) Total number of solutions for equation in case of x₁ ≥ 1, is equals to the 10626.
b) Total number of solutions for equation in case of xᵢ ≥ 2 for i = 1, 2, 3, 4, 5, is equals to the 1365.
c) Total number of solutions for equation in case of 0 ≤ x₁ ≤ 10 is equals to the 11649.
d) Total number of solutions for equation in case of 0 ≤ x₁ ≤ 3, 1 ≤ x₂ < 4, and x₃ ≥ 15, is equals to the 76.
We have an equation x₁ + x₂ + x₃ + x₄ + x₅ = 21, where xᵢ , i = 1, 2, 3, 4, 5 and we have to determine the number of solution of equation.
a) Solution of equation when x₁ ≥ 1
Let there are 5 boxes namely, x₁,x₂,x₃,x₄,x₅ in which 21 balls are placed distinguished. First ball is placed in box x₁. So, remained 20 balls are placed into 5 boxes with repititions. So, number of ways are C(n+r−1, r-1) = (n + r − 1)!/(r-1)!n! , where n = 20 , r = 5
C(n + r −1, r- 1) = C(20 + 5− 1 ,4)
= C(24,4) = 10626
b) Solution of equation for xᵢ ≥ 2 for i = 1,2,3,4,5.
Now, xᵢ ≥ 2 for i = 1,2,3,4,5, means first drop two balls into every box. Then, only 11 balls, remaining
n =11, r = 5
C(n+r−1, r-1) = (n+r−1)!/(r-1)!n!
= C(11 + 5−1, 4) = C(15, 4)
= 1365
c) Solution of equation for 0 ≤ x1 ≤ 10
when 21 balls dropped into five boxes x₁, x₂, x₃, x₄,x₅ then C(n+r−1, r-1) = (n+r−1)!/(r-1)!n! ; n= 21, r = 5
C(n + r −1, r - 1) = C(21+ 5− 1 ,4)
C(25, 4) = 12650
xi ≥ 11 , n=11, r = 5 then
C(n + r−1, r- 1 ) = C(11+4−1,4)
C(14,4) = 1001
C(25,4) − C(14,4) = 12650 − 1001 = 11649
d) Solution of equation for 0 ≤ x₁≤ 3, 1 ≤ x₂ < 4, and x₃≥ 15. For this condition solution is = { x1≥ 0, x2≥ 0, x3 ≥ 15} - { x₁≥3, x₃≥ 15} - { x₂≥4, x₃≥ 15} - { x₁=0, x₃ ≥ 15}
Now, first 15 balls are dropped into x3 and remaining 6 are droped into remaining boxes, { x₁ ≥ 0, x₂≥ 0, x₃≥ 15}, Then, n = 6, r = 5
C(n + r −1, r - 1) = C(6+ 5− 1 ,4)
C(10, 4) = 210
Also, { x₁ ≥3, x₃ ≥ 15}, represents 3 and 15 balls are dropped into x₁ and x₃ respectively. and remaining 3 balls will dropped into 5 boxes with repititions, n = 3, r = 5
C(n + r −1, r - 1) = C(3+ 5− 1 ,4)
C(7, 4) = 35 ways
{ x₂≥4, x₃≥ 15} , represents 4 and 15 balls are dropped into x₂ and x₃ respectively. and remaining 2 balls will dropped into 5 boxes with repititions, n= 2, r = 5
C(n + r −1, r - 1) = C(5+ 4− 1 ,4)
C(7, 3) = 15 ways
{ x₂ = 0, x₃ ≥ 15}, represents 0 and 15 balls are dropped into x₂ and x₃ respectively. and remaining 6 balls will dropped into 4 boxes with repititions, n= 6, r= 4
C(n + r −1, r - 1) = C(6+ 4− 1 ,3)
C(9, 3) = 84 ways
So, the number of solutions for this case = 210 - 35 - 15 - 84 = 76.
Hence there are 76 non-negative integer solutions.

An object is moving with velocity (in ft/sec) v(t)=t2−1t−12
Find the displacement and total distance travelled from t=0 to t=6
To find the displacement and total distance traveled by the object from t=0 to t=6, we need to integrate the velocity function over the given time interval.
The displacement can be found by integrating the velocity function v(t) with respect to t over the interval [0, 6]. The integral of v(t) represents the net change in position of the object during this time interval.
The total distance traveled can be determined by considering the absolute value of the velocity function over the interval [0, 6]. This accounts for both the forward and backward movements of the object.
Now, let's calculate the displacement and total distance traveled using the given velocity function v(t) = t^2 - (1/t) - 12 over the interval [0, 6].
To find the displacement, we integrate the velocity function as follows:
Displacement = ∫[0,6] (t^2 - (1/t) - 12) dt.
To find the total distance traveled, we integrate the absolute value of the velocity function as follows:
Total distance = ∫[0,6] |t^2 - (1/t) - 12| dt.
By evaluating these integrals, we can determine the displacement and total distance traveled by the object from t=0 to t=6.

(The top one please)
Answer:
y=-6.
Step-by-step explanation:
1) the condition f(-1)=-6 and f(4)=-6 mean points A and B have coordinates (-1;-6) and (4;-6);
2) the points A and B has the same y-coordinate, it means, the required line is parallel to the x-axis and the required function is: y=-6.
P.S. the suggested way is not the only one.
The linear function f is f(x) = -6.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(-1) = -6
f(4) = -6
The linear function f can be in the form of f(x) = mx + c.
Now,
m = (-6 + 6) / (4 - 1)
m = 0/3
m = 0
Now,
f(-1) = -6
x = -1
f(x) = mx + c
f(-1) = 0 x -1 + c
-6 = 0 + c
c = -6
Now,
f(x) = -6
Thus,
The function f is a constant function.

A roller-coaster is at the top of a 62-meter hill. the car and its passengers have a total mass of 1,088 kilograms. by the time the car reaches the bottom of the hill, its speed is 74 miles per hour (33 meters per second). how much kinetic energy does the car have at the bottom of the hill?
The kinetic energy of the roller coaster at the bottom of the hill is approximately 594,576 J.
The potential energy of the roller coaster at the top of the hill can be calculated as:
PE = mgh
where m is the mass of the car and its passengers, g is the acceleration due to gravity \((9.8 m/s^2\)), and h is the height of the hill (62 m). Thus, we have:
PE =\((1088 kg)(9.8 m/s^2)(62 m) = 670,720 J\)
At the bottom of the hill, all of the potential energy has been converted to kinetic energy. The kinetic energy of the roller coaster can be calculated as:
\(KE = (1/2)mv^2\)
where v is the speed of the roller coaster at the bottom of the hill. Thus, we have:
\(KE = (1/2)(1088 kg)(33 m/s)^2 = 594,576 J\)
Therefore, the kinetic energy of the roller coaster at the bottom of the hill is approximately 594,576 J.
