Answer:
C
Step-by-step explanation:
Short explanation:
Using the unit circle, the answer is C.
If you want a full in depth, answer:
The unit circle has a radius of 1.
3pi/4 is located in the 2nd quadrant.
That radian measures 135 degrees.
The 2nd quadrant start after 90 degrees.
To find the terminal angle, subtract 90 from 135.
Which gives you 45.
This means we are dealing with a 45-45-90 triangle.
Since our hypotenuse is 1, our y and x have to be
[tex] \frac{ \sqrt{2} }{2} [/tex]
Sin is positve in the 2nd quadrant so C is the answer.

Hey love! x = 6
Step-by-step explanation:
because 13 x 6 = 78
HOPE THIS HELPS!
Answer:
x = 6
Work -
13x = 78
divide 13 on both sides to isolate x. 78 divided by 13 gives us 6, and 13/13 =1.
1 times x is x, as you can see, we have isolated x on one side. On the other side, we got 6, so x = 6

Answers
Answer: [tex](0,0), (3,-27)[/tex]
Step-by-step explanation:
Given
Curve is [tex]y=x^4-4x^3[/tex]
The stationary point on a differentiable function is the points where the differentiation of the function is zero i.e. slope is zero at that point.
Differentiate the curve [tex]f(x)=x^4-4x^3[/tex]
[tex]\Rightarrow f'(x)=4x^3-12x^2[/tex]
Equate it to zero
[tex]\Rightarrow 4x^3-12x^2=0\\\Rightarrow 4x^2(x-3)=0\\\Rightarrow x=0,0,3[/tex]
Put [tex]x=0,3[/tex] in the function [tex]f(x)=x^4-4x^3[/tex]
[tex]\Rightarrow f(0)=0\\\Rightarrow f(3)=3^4-4(3)^3\\\Rightarrow f(3)=81-108\\\Rightarrow f(3)=-27[/tex]
Therefore, the stationary points are [tex](0,0), (3,-27)[/tex]

Find the upper bound for the following length:
A) 18.7cm correct to 1 decimal place.
B) 58.37cm correct to 2 decimal places.
Please help.
Answers
Part A
Let's say we measure a board length and we measure 18.639 cm. Now let's say we round to the nearest tenth. That would lead to 18.6 cm. The question is "What is the largest value we can measure such that we round to the nearest tenth to get 18.7 cm?"
Well we could measure 18.7 cm exactly, but there are values we could measure that are larger to round to that value. We could measure 18.71 or 18.72, etc etc all the way up to 18.74; once we get to 18.75, it will round to 18.8
So this means that the largest we can measure is 18.74 and it is the upper bound we're after.
Answer: 18.74 cm=========================================================
Part B
We use the same idea as part A, but now we're extending out one more decimal place.
We could measure 58.37 cm exactly or we could measure 58.371 or we could do 58.372, etc until we arrive at 58.374
By the time we get to 58.375, it will round to 58.38 and that's not what we're after. So the highest we can go is 58.374 cm
Answer: 58.374 cmIn ΔWXY, w = 410 inches, x = 530 inches and y=830 inches. Find the area of ΔWXY to the nearest 10th of an square inch.
Answers
Answer:
90,597 square inches
Step-by-step explanation:
In ΔWXY, w = 410 inches, x = 530 inches and y=830 inches. Find the area of ΔWXY to the nearest 10th of an square inch.
We solve using Heron's formula
A = √s(s -a)(s - b) (s - c)
s = a + b + c/2
a = 410 inches
b = 530 inches
c = 830 inches
Hence,
s = 410 + 530 + 830/2
s = 885
A = √885(885 - 410)(885 - 530)(885 - 830)
A = 90,597.030166557 square inches
Approximately = 90,597.0 square inches

Jamya is making a rectangular blanket. The length of the blanket is 10inches greater than it's worth, W, in inches. Write the function, f(w), that describes the area, in square inches, of Jamya's blanket as a function of the width, w.
Answers
Answer: (w² + 10)inches²
Step-by-step explanation:
Since the width of the rectangular blanket is given as w and the length of the blanket is 10inches greater than it's width, therefore the length will be:
= 10 + w.
Therefore,
length = 10 + w
width = w
Area = length × width
Area = (10 + w) × w
Area = 10w + w²
Therefore, the area of the blanket will be (w² + 10)inches².

in figure 5.19 to the right PQRS is a rectangle. if PS=5cm and PR=13cm find SR and QS.
Answers
Given:
PQRS is a rectangle.
[tex]PS=5\ cm,\ PR=13\ cm[/tex]
To find:
The length of SR and QS.
Solution:
We know that, all interior angles of a rectangle are right angle. So, [tex]\angle S=90^\circ[/tex].
According to the Pythagoras theorem, in a right angle triangle,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
Using Pythagoras theorem in triangle PRS, we get
[tex]PR^2=PS^2+SR^2[/tex]
[tex]13^2=5^2+SR^2[/tex]
[tex]169-25=SR^2[/tex]
[tex]144=SR^2[/tex]
Taking square root on both sides.
[tex]\sqrt{144}=SR[/tex]
[tex]12=SR[/tex]
So, the measure of SR is 12 cm.
We know that the diagonals of a rectangle are equal. PR and QS are the diagonals of the rectangle PQRS. So,
[tex]PR=QS[/tex]
[tex]13=QS[/tex]
Therefore, the length of SR is 12 cm and the length of QS is 13 cm.

Yasmine's Mom had to buy 9 pints of ice cream and each pint cost $2.73 (tax is included in that cost). How much did the 9 pints of ice cream cost? If she paid for the ice cream with $40, how much money did she get back?
Answers
Answer:
$24.57
$15.43
Step-by-step explanation:
Cost per pint of ice cream = $2.73
Number of pints purchased = 9
Total cost = cost per pint * Number of pints
Total cost = $2.73 * 9 = $24.57
If she paid $40
Change collected = $40 - $24.57 = $15.43

find the lcm of m²+2m, m²- 4 ,m² + 3 m+2 plzzzz answer fast
Answers
Answer:
(m + 2)
Step-by-step explanation:
First, factorise out m from the first equation:
m² + 2m = m (m + 2)
Second, use difference of two squares to factorise the 2nd equation:
m² - 4 = (m + 2) (m - 2)
Third, just factorise the last one normally as you would to solve for m:
m² + 3m + 2 = (m + 2) (m + 1)
Finally, to find the lowest common multiple, you need to identify what value goes into all of the equations and that is (m + 2).
