What is mLUTV?
Since LPTS is a right angle, LPTR and
LRTS are complementary angles.
x + (2x-57) = 90
3x - 57 = 90
3x = 147
X = 49
So, m/UTV = 41°.

LRTS and LUTV are vertical angles,

−7.886i − 2.957j
−11.828i − 6.900j
Answer:
(b) -7.275i -4.244j
Step-by-step explanation:
The projection of vector u onto vector v is the product of the unit vector v, the magnitude of vector u, and the cosine of the angle between them.
__
The dot product gives the product of the magnitudes of the two vectors and the cosine of the angle between them. To find the projection, we must divide the dot product by the magnitude of v and multiply by the unit vector in the direction of v.
[tex]proj(u,v)=(\vec{u}\cdot\vec{v})\cdot\dfrac{\vec{v}}{|\vec{v}|^2}=\dfrac{((-8)(-12)+(-3)(-7))(-12\vec{i}-7\vec{j})}{(-12)^2+(-7)^2}\\\\=\dfrac{-(96+21)(12\vec{i}+7\vec{j})}{144+49}=-\dfrac{117}{193}(12\vec{i}+7\vec{j})\approx\boxed{-7.275\vec{i}-4.244\vec{j}}[/tex]

The sum of two polynomials is 8d5 – 3c3d2 + 5c2d3 – 4cd4 + 9. If one addend is 2d5 – c3d2 + 8cd4 + 1, what is the other addend?
6d5 – 2c3d2 + 5c2d3 – 12cd4 + 8
6d5 – 4c3d2 + 3c2d3 – 4cd4 + 8
6d5 – 4c3d2 + 5c2d3 – 12cd4 + 8
6d5 – 2c3d2 – 3c2d3 – 4cd4 + 8
By subtracting the given addend to the sum, we see that the other addend is:
[tex]6d^5 - 2c^3d^2 + 5c^2d^3 - 12cd^4 - 8[/tex]
How to get the other addend?
We know that the sum of two polynomials is:

A sinusoidal function whose period is 4π, maximum value is 6, and minimum value is -2 has
a y intercept of 6.
What is the equation of the function described?
The equation for the sinusoidal function described is given as follows:
[tex]y = 4\cos{\left(\frac{1}{2}x\right)} + 2[/tex]
What is a sinusoidal function?We want a function with a y-intercept at it's maximum value, hence we use the cosine equation, given by:
[tex]y = A\cos{\left(\frac{2\pi}{B}x\right)} + C[/tex]
In which:
2A is the amplitude, which is the difference between the largest and smallest value.B is the period.C is the vertical shift, considering that the standard cosine function has range between -A and A.The amplitude is of 8, hence 2A = 8 -> A = 4. This would represent a function between -4 and 4, but we want between -2 and 6, hence the vertical shift is of C = 2.
As for the period, we have that:
[tex]B = 4\pi[/tex]

If 48 people chose winter, then how many people were surveyed?
A.29
B.32
C.80
D.128
Answer:
C. 80Step-by-step explanation:
Let the number of people were surveyed is x.
We have 60% of x is 48 people.
Set this as equation and solve:
60% of x = 48x*60/100 = 480.6x = 48x = 48/0.6x = 80Correct choice is C.
Answer:
C. 80
Step-by-step explanation:
Given:
60% = 48 peopleLet x be the total number of people surveyed.
Set up a ratio of people to percentage and solve for x:
[tex]\implies \sf 48 : 60 = x : 100[/tex]
[tex]\implies \sf \dfrac{48}{60}=\dfrac{x}{100}[/tex]
[tex]\implies \sf x=100 \cdot \dfrac{48}{60}[/tex]
[tex]\implies \sf x=\dfrac{4800}{60}[/tex]
[tex]\implies \sf x=\dfrac{480}{6}[/tex]
[tex]\implies \sf x=80[/tex]
Therefore, the total number of people who were surveyed was 80.

Complete Question:
A rectangular prism has a length of 7 m, a height of 5 m, and a volume of 140 m³. What is the width? A prism has a length of 7 meters, width of w, and height of 5 meters.
Which steps are correct? Check all that apply.
a) Substitute the known values into the formula: 140 = 7(w)(5).
b) Substitute the known values into the formula: 7 = 140(w)(5).
c) Substitute the known values into the formula: 5 = 7(w)(140).
d) Solve for the unknown: w = 4 m.
e) Solve for the unknown: w = 7 m.
f) Solve for the unknown: w = 2 m.
Answer:
a) Substitute the known values into the formula: 140 = 7(w)(5).
d) Solve for the unknown: w = 4 m.
Step-by-step explanation:
The steps that are correct are Options a) and d). This is because:
Step 1
The volume of a rectangular prism is calculated as:
Volume of a rectangular prism = Length (l) × Width(w) × Height(h)
The unit of the volume or a rectangular prism is in cubic metres (m³)
In the question, we are asked to find the unknown value which is the width and we were given the following known values:
Length = 7 m,
Height = 5 m
Volume = 140 m³
Step 2
Solve for the unknown value( Width)
Volume of a rectangular prism = Length (L) × Width(W) × Height(H)
140m³ = 7m × Width(m) × 5m
140m³ = 35m² × Width(m)
Width(w) = 140m³ ÷ 35m²
Width(w) = 4m
Hence, the unknown Width(w) = 4m
From the above explanation we can see that the correct steps is Option a) and Option d)
Answer:
Step-by-step explanation:
Volume of rectangular prism= Length x width x height
V=L x W x H
140=7 x W x 5
140= 35 x w
W= 140/35
W= 4

A motorboat travels 464 kilometers in 8 hours going upstream and 644 kilometers in 7 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
Rate of boat in still water ______km/h
Rate of current: _______ km/h
Let's say you are paddling at 5mph and the current is 3 mph. Going upstream, you are going 2 mph and downstream, 8 mph.
8(b - c) = 464
7(b + c) = 644
b - c = 58
b + c = 92
Adding the two together
2b = 150
b = 75
75 - c = 58
c = 17
The boat's speed is 75 mph and the current's speed is 17 mph.
calculates the sum of the first 8 terms of an arithmetic progression starting with 3/5 and ending with 1/4
We conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.
How to get the sum of the first 8 terms?
In an arithmetic sequence, the difference between any two consecutive terms is a constant.
Here we know that:
[tex]a_1 = 3/5\\a_8 = 1/4[/tex]
There are 7 times the common difference between these two values, so if d is the common difference:
[tex]a_1 + 7*d = a_8\\\\3/5 + 7*d = 1/4\\\\7*d = 1/4 - 3/5 = (5 - 12)/20 = -7/20\\\\d = -1/20[/tex]
Then the sum of the first 8 terms is given by:
[tex]3/5 + (3/5 - 1/20) + (3/5 - 2/20) + ... + (3/5 - 7/20)\\\\8*(3/5) - (1/20)*(1 + 2 + 3+ 4 + 5 + 6 + 7) = 3.4 = 34/10 = 17/5[/tex]

Hello there!
We have two methods to solve this problem.
Substitution methodElimination method.We will limit ourself to Substitution method.
3x – 2y = -4.................... 1.
4x + 2y = 25................... 2.
First lets manipulate eq.2 in terms of y.
4x + 2y = 25
2y = 25 - 4x
y = 25/2 - 2x .............. eq.3
Substitute eq.3 into eq.1
3x – 2(25/2 -2x) = -4
Solve for x.
Opening the brackets
3x - 25 - 4x = -4
-x = 21
x = -21
Substitute x into equation 3
y = 25/2 - 2x
=> y = 25/2 - 2(-21)
= 54.5
In terms of x and y; (x,y)
= (-21, 54.5)
