Answer:
resultant force: 93.946∠-10.62° Nline of action: 17.314x +92.337y = 809.433Step-by-step explanation:
We can use the notation a∠b to represent the (x, y) components (a·cos(b), a·sin(b)), where angle b is measured CCW from the +x direction. If we label the forces a, b, c, d clockwise from A, then we have ...
a = 80∠0° = (80, 0)
b = 60∠90° = (0, 60)
c = 90∠45° = (63.640, 63.640)
d = 150∠-110° = (-51.303, -140.954)
__
If we label point A the origin, then the clockwise torque on point A is the sum of products of the force x-component and its y location, and its y-component and the negative of its x location.
T = (0, 0)·(80, 0) +(3, 0)·(0, 60) +(3, -8)·(63.640, 63.640) +(0, -8)·(-51.303, -140.954)
T = 809.433 . . . . n·m, the CW torque on point A
__
The sum of forces is ...
F = a +b +c +d = (92.337, -17.314) = 93.946∠-10.62° . . . N
__
This force, applied to the point of application, must generate the same torque as the given forces. That is ...
F·(y, -x) = 809.433
Then the equation of the line of action is ...
17.314x +92.337y = 809.433 . . . . . x and y in meters measured from A
Any point (x, y) on this line will serve as a point of application of the force. Unfortunately, this line of action does not pass through the rectangular plate. The attachment shows the point (D) on the line of action that is closest to point A.
_____
Additional comment
The resultant force could be decomposed into two forces acting on the rectangular plate. One could be of much larger magnitude, operating at the corner opposite point A. This force would provide the necessary torque. Another would be acting on point A, providing no torque, but with components such that the resultant has the correct magnitude and direction.

Round the number 74.054 to the nearest tenth
Answer:
74.054 rounded to the nearest tenth is equivalent to 74.1
Step-by-step explanation:
Since you're rounding 74.054 to the nearest tenth, you need to focus on the hundredths place. If the number on the hundredths place is greater than or equal to 5, then you round up. If not, keep the number in the tenths place the same. In this case, 5 is in the hundredths place, which means you need to round the 0 in the tenths place up by 1. So 74.054 rounded to the nearest tenths is equivalent to 74.1.

The discriminant if a quadratic equation is negative. One solution is 4 + 7i. What is the other solution? *
7 - 4i
4 - 7i
- 4 + 7i
7 + 4i
==========================================================
Explanation:
When you have a quadratic in the form ax^2 + bx + c = 0, where a,b,c are real numbers, then a negative discriminant leads to having a pair of complex roots. The roots come in conjugate pairs meaning that p+qi is one root while p-qi is the other root. The p,q are real numbers.
In the case of 4+7i being one root, we have p = 4 and q = 7, since it matches with p+qi. The other root must be 4-7i since it matches with p-qi.
In short, we flip the plus to a minus when going from 4+7i to 4-7i. All of this applies when we have a,b,c as real numbers.
If we allowed a,b,c to be complex numbers, then the roots may not necessarily come in conjugate pairs.

What is the slop and the y-intercept on the graph?
Answer:
Slope= 2 ; y intercept= 4
Step-by-step explanation:
Slope: (y2 - y1)/(x2-x1) where x and y indicate the coordinates of two points
Slope = (4-0)/(0-(-2) = 4/2 = 2
y intercept is where the line intercepts the y axis: it happens in (0;4)
Answer:

A pyramid has a square base of length 8cm and a total surface area of 144cm². Find the volume of the pyramid. (Please use Pythagoras' Theorem thank you)
Answer:
[tex] \displaystyle V_{ \text{pyramid}}= 64 \: {cm}^{3} [/tex]
Step-by-step explanation:
we are given surface area and the length of the square base
we want to figure out the Volume
to do so
we need to figure out slant length first
recall the formula of surface area
[tex]\displaystyle A_{\text{surface}}=B+\dfrac{1}{2}\times P \times s[/tex]
where B stands for Base area
and P for Base Parimeter
so
[tex] \sf\displaystyle \: 144=(8 \times 8)+\dfrac{1}{2}\times (8 \times 4) \times s[/tex]
now we need our algebraic skills to figure out s
simplify parentheses:
[tex] \sf\displaystyle \: 64+\dfrac{1}{2}\times32\times s = 144[/tex]
reduce fraction:
[tex] \sf\displaystyle \: 64+\dfrac{1}{ \cancel{ \: 2}}\times \cancel{32} \: ^{16} \times s = 144 \\ 64 + 16 \times s = 144[/tex]
simplify multiplication:
[tex] \displaystyle \: 16s + 64 = 144[/tex]
cancel 64 from both sides;
[tex] \displaystyle \: 16s = 80[/tex]
divide both sides by 16:
[tex] \displaystyle \: \therefore \: s = 5[/tex]
now we'll use Pythagoras theorem to figure out height
according to the theorem
[tex] \displaystyle \: {h}^{2} + (\frac{l}{2} {)}^{2} = {s}^{2} [/tex]
substitute the value of l and s:
[tex] \displaystyle \: {h}^{2} + (\frac{8}{2} {)}^{2} = {5}^{2} [/tex]
simplify parentheses:
[tex] \displaystyle \: {h}^{2} + (4 {)}^{2} = {5}^{2} [/tex]
simplify squares:
[tex] \displaystyle \: {h}^{2} + 16 = 25[/tex]
cancel 16 from both sides:
[tex] \displaystyle \: {h}^{2} = 9[/tex]
square root both sides:
[tex] \displaystyle \: \therefore \: {h}^{} = 3[/tex]
recall the formula of a square pyramid
[tex]\displaystyle V_{pyramid}=\dfrac{1}{3}\times A\times h[/tex]
where A stands for Base area (l²)
substitute the value of h and l:
[tex] \sf\displaystyle V_{ \text{pyramid}}=\dfrac{1}{3}\times \{8 \times 8 \}\times 3[/tex]
simplify multiplication:
[tex] \sf\displaystyle V_{ \text{pyramid}}=\dfrac{1}{3}\times 64\times 3[/tex]
reduce fraction:
[tex] \sf\displaystyle V_{ \text{pyramid}}=\dfrac{1}{ \cancel{ 3 \: }}\times 64\times \cancel{ \: 3}[/tex]
hence,
[tex] \sf\displaystyle V_{ \text{pyramid}}= 64 \: {cm}^{3} [/tex]

Jen and Kim are together in the park. Jen walks 50 feet north while Kim walk 40 feet west. How far apart are they after their walk?
Answer:
30 ft
Step-by-step explanation:
This situation forms a right triangle
a ² +b ²= c ²

2,500 + 1,600 = c ²
900 = c ²
√900 = √c²

A right prism has a volume of 65 cubic inches. The prism is enlarged so its height is increased by a factor of 20, but the other dimensions do not change. What is the new volume? A.1000 in .3 B.1300 in .3 C.1200 in. 3 D. 1100 in.3
Answer:
Volume of a right prism = 65 cubic inches
Its height is increased by a factor of 20.
To find:
The new volume of the prism if the other dimensions do not change.
Solution:
The volume of a prism is:
[tex]Volume=Bh[/tex]
Where, B is the base area and h is the height.
A right prism has a volume of 65 cubic inches.
[tex]65=Bh[/tex]
The height of prism is increased by a factor of 20. So, the new volume is:
[tex]Volume=B(20h)[/tex]
[tex]Volume=20(Bh)[/tex]
[tex]Volume=20(65)[/tex]
[tex]Volume=1300[/tex]
The volume of the new prism is 1300 in³.
Therefore, the correct option is B.
