The magnitude of the resultant force ||FR|| is 80.55 N.
The weight of the box is acting straight downward, perpendicular to the incline, so it does not affect the magnitude of the resultant force parallel to the incline. Therefore, we only need to consider the force of 150 N pushing the box up the incline.
Let's call the angle between the force of 150 N and the incline "theta". We can find theta by subtracting 58 degrees from 90 degrees (since the incline is at an angle of 58 degrees with respect to the horizontal). So:
theta = 90 degrees - 58 degrees
theta = 32 degrees
Now we can use trigonometry to find the component of the force of 150 N parallel to the incline. We'll use sine, since we know the hypotenuse (the force) and the opposite side (the component parallel to the incline):
sin(theta) = opposite/hypotenuse
sin(32 degrees) = ||FR||/150 N
Solving for ||FR||, we get:
||FR|| = 150 N * sin(32 degrees)
||FR|| ≈ 80.55 N
Therefore, the magnitude of the resultant force is approximately 80.55 N.

Find the second smallest number that has 1, 2, 3, 4, and 5 as factors...
The second smallest number that has 1, 2, 3, 4, and 5 as factors is 360.
What is factorization?
A number or other mathematical object is factorization or factored when it is written as the product of numerous factors, often smaller or simpler things of the same sort.
To find the smallest number that has 1, 2, 3, 4, and 5 as factors, we can simply multiply these numbers together, since they are all factors of their product:
1 × 2 × 3 × 4 × 5 = 120
Now we need to find the second smallest number with these factors. One way to approach this is to list out the multiples of 120 until we find a number that also has the factors 1, 2, 3, 4, and 5, and is larger than 120.
Multiplying 120 by 2, 3, 4, 5, and 6 gives us the multiples:
240, 360, 480, 600, 720
Checking each of these multiples, we see that only 360 has all the factors 1, 2, 3, 4, and 5. Therefore, the second smallest number that has 1, 2, 3, 4, and 5 as factors is 360.

consider the system obtained from the following augmented matrix

for which values of k will the corresponding system be inconsistent
The values of k that make the system inconsistent are k = 0 and k = 2.
The system obtained from the given augmented matrix is:
```
1 2 -1 | 4
0 -1 1 | 3
0 0 k^2-2k | -3k-3
```
For the system to be inconsistent, the last equation must be a contradiction, meaning that the coefficients of the variables are all zero but the constant term is nonzero. In other words, we need `k^2-2k = 0` and `-3k-3 ≠ 0`.
Solving for k in the first equation, we get:
```
k^2-2k = 0
k(k-2) = 0
```
So k = 0 or k = 2.
However, we also need `-3k-3 ≠ 0`, which means that k ≠ -1. Therefore, the values of k that make the system inconsistent are k = 0 and k = 2.

Answer:
CD = 22
Step-by-step explanation:
You would double the side lengths given since this is a rectangle and set them equal to 80 cause that is the perimeter. So the equation would be 6z + 6 + 8z + 4 = 80. You would use the PEDMAS rule and subtract 6 from both sides which gives you:
6z + 8z +4 = 74
Subtract 4 from both sides
6z + 8z = 70
Add 6z + 8z
14z = 70
Divide 70 and 14z
z = 5.
AB and CD is equal in length so all you have to do is plug in 5 to z in the AB equation.

the polynomial in factored form as a produ f(x)=12x^(5)+5x^(4)-39x^(3)+9x^(2)+19x-6
The polynomial in factored form as a product can be found by using the factor theorem and synthetic division. The factor theorem states that if f(a) = 0, then (x-a) is a factor of f(x). We can use synthetic division to find the factors of f(x)=12x^(5)+5x^(4)-39x^(3)+9x^(2)+19x-6.
First, we need to find a value of x that makes f(x) = 0. We can use the rational root theorem to find possible rational roots. The possible rational roots are ±1, ±2, ±3, ±6. We can use synthetic division to test these possible roots.
Using synthetic division with x = 1, we get a remainder of -1, so x = 1 is not a root. Using synthetic division with x = -1, we get a remainder of 0, so x = -1 is a root and (x+1) is a factor of f(x).
Now we can divide f(x) by (x+1) using synthetic division to get the quotient 12x^(4)-7x^(3)-32x^(2)+41x-6. We can repeat the process of finding possible rational roots and using synthetic division to find the factors of this quotient.
The possible rational roots of the quotient are ±1, ±2, ±3, ±6. Using synthetic division with x = 1, we get a remainder of 8, so x = 1 is not a root. Using synthetic division with x = -1, we get a remainder of 0, so x = -1 is a root and (x+1) is a factor of the quotient.
We can divide the quotient by (x+1) using synthetic division to get the new quotient 12x^(3)-19x^(2)-13x+6. We can repeat the process of finding possible rational roots and using synthetic division to find the factors of this new quotient.
The possible rational roots of the new quotient are ±1, ±2, ±3, ±6. Using synthetic division with x = 1, we get a remainder of -14, so x = 1 is not a root. Using synthetic division with x = -1, we get a remainder of 0, so x = -1 is a root and (x+1) is a factor of the new quotient.
We can divide the new quotient by (x+1) using synthetic division to get the new quotient 12x^(2)-31x+6. We can repeat the process of finding possible rational roots and using synthetic division to find the factors of this new quotient.
The possible rational roots of the new quotient are ±1, ±2, ±3, ±6. Using synthetic division with x = 1, we get a remainder of -13, so x = 1 is not a root. Using synthetic division with x = -1, we get a remainder of 49, so x = -1 is not a root. Using synthetic division with x = 2, we get a remainder of 0, so x = 2 is a root and (x-2) is a factor of the new quotient.
We can divide the new quotient by (x-2) using synthetic division to get the new quotient 12x-3. This quotient cannot be factored further, so the factors of f(x) are (x+1)(x+1)(x+1)(x-2)(12x-3).
Therefore, the polynomial in factored form as a product is f(x) = (x+1)(x+1)(x+1)(x-2)(12x-3).

A jar contains 54 coins consisting of quarters and dimes. The total value of the coins is $16.85. Which system of equations can be used to determine the number of quarters, q, and the number of dimes, d, in the
jar?
Answer:
Let q be the number of quarters in the jar and d be the number of dimes in the jar.
The total number of coins in the jar is given as 54, so we can write:
q + d = 54
The total value of the coins is $16.85. We can express this as the sum of the values of the quarters and the dimes in the jar:
0.25q + 0.10d = 16.85
Therefore, the system of equations that can be used to determine the number of quarters and dimes in the jar is:
q + d = 54
0.25q + 0.10d = 16.85

The sum of the digits of the number which when added to 2000 makes the resulting number divisible by 12,16,18 and 21 is 7
The smallest number which when added to 2000 makes the resulting number divisible by 12, 16, 18, and 21 is 312. The sum of the digits of x is 3 + 1 + 2 = 6.
To find the smallest number x that can be added to 2000 to make the resulting number divisible by 12, 16, 18, and 21, we need to find the least common multiple (LCM) of these numbers.
The LCM of 12, 16, 18, and 21 is 1008. Then we need to find the smallest multiple of 1008 that is greater than 2000. This is 1008 * 3 = 3024. The difference between 3024 and 2000 is 1024, so x = 1024.The sum of the digits of x is 1 + 0 + 2 + 4 = 7. Therefore, the sum of the digits of x is 7.

7. Solve the radical equations: (a)x2+3=x+4(b)2x−1−x−4=2
a. The equation "(a) x2+3=x+4" gives the solution as x = 1.
b. The equation "(b) 2x-1-x-4=2" gives the solution as x = -1.
To solve these radical equations, we will need to isolate the radical on one side of the equation and then square both sides to get rid of the radical. After that, we can solve for x using standard algebraic methods.
(a) x2+3=x+4
First, we will isolate the radical on one side of the equation:
x2+3=x+4
x2=x+4-3
x2=x+1
Now, we will square both sides of the equation to get rid of the radical:
(x2)2=(x+1)2
x4=x2+2x+1
Next, we will rearrange the equation and set it equal to zero:
x4-x2-2x-1=0
Now, we can use the quadratic formula to solve for x:
x=(-(-2)±√((-2)2-4(1)(-1)))/(2(1))
x=(2±√(4+4))/(2)
x=(2±√8)/(2)
x=(2±2√2)/(2)
x=1±√2
So, the solutions for x are 1+√2 and 1-√2.
(b) 2x−1−x−4=2
First, we will isolate the radical on one side of the equation:
2x−1=x−4+2
2x−1=x−2
Now, we will square both sides of the equation to get rid of the radical:
(2x−1)2=(x−2)2
4x2-4x+1=x2-4x+4
Next, we will rearrange the equation and set it equal to zero:
3x2=3
Now, we can solve for x by dividing both sides of the equation by 3 and taking the square root:
x2=1
x=±√1
x=±1
So, the solutions for x are 1 and -1.

The hypotenuse of a right triangle measures 2√15 centimeters and its shorter leg measures 2√6
centimeters. What is the measure of the larger acute angle of the triangle? Round your answer to the nearest tenth of a degree.
Answer: Let's use the trigonometric ratio of sine to find the measure of the larger acute angle of the right triangle. We have:
sin(theta) = opposite / hypotenuse
where theta is the measure of the larger acute angle, and opposite is the length of the shorter leg of the right triangle. Substituting the given values, we get:
sin(theta) = 2sqrt(6) / 2sqrt(15)
= sqrt(2/5)
Using a calculator, we can find the value of theta to the nearest tenth of a degree:
theta = arcsin(sqrt(2/5))
≈ 38.2°
Therefore, the measure of the larger acute angle of the right triangle is approximately 38.2 degrees.

QUESTION 4 4.1 Calculate the difference between the interest of the following two investmen A and B. A. R5 500 Simple interest 8% for 4 years Grade 9 B. R5 500 Compound interest 7,5% for 3 years
The difference in interest earned between the twο investments is R5 118.08.
Describe Interest?There are twο main types οf interest: simple interest and cοmpοund interest. Simple interest is calculated οnly οn the principal amοunt, while cοmpοund interest is calculated οn bοth the principal amοunt and any accumulated interest frοm previοus periοds.
Interest rates can be fixed οr variable. A fixed interest rate remains the same thrοughοut the lοan οr investment periοd, while a variable interest rate can change οver time depending οn market cοnditiοns.
Interest is an impοrtant cοncept in finance and ecοnοmics, and it plays a key rοle in bοrrοwing and lending, investments, and savings.
Investment A:
Simple interest = P × r × t
Where P = R5 500, r = 8% = 0.08 and t = 4 years
Simple interest = 5500 × 0.08 × 4
Simple interest = 1760
Investment B:
Cοmpοund interest = [tex]$A = P(1 + \frac{r}{n})^{nt}[/tex]
Where P = R5 500, r = 7.5% = 0.075, n = 1 (as it is cοmpοunded annually) and t = 3 years
Cοmpοund interest = [tex]$5500 \times (1 + \frac{0.075}{1} )^{(1 \times 3)} - 5500[/tex]
Cοmpοund interest = 1332.63
The difference between the interest earned οn the twο investments is:
Difference = Investment A - Investment B
Difference = 1760 - 1332.63
Difference = 427.37
Therefοre, the difference in interest earned between the twο investments is R5 118.08.
