Answer:
-1/2
Step-by-step explanation:
Use the two points shown.
slope = rise/run
Start at teh left point.
Go down 2 units. That is a rise of -2.
Now go right 4 units. That is a run of 4.
slope = rise/run = -2/4 = -1/2
The reference angle for (5pi)/4 is pi/4 , which has a terminal point of (sqrt2/2), (sqrt2/2). What is the terminal point of 5pi/4?
Using the unit circle, it is found that the terminal point of the angle 5pi/4 is given by:
A. [tex]\left(-\frac{\sqrt{2}}{2}, -\frac{\sqrt{2}}{2}\right)[/tex]
What is the unit circle?For an angle [tex]\theta[/tex] the unit circle is a circle with radius 1 containing the following set of points: [tex](\cos{\theta}, \sin{\theta})[/tex].
The angle 5pi/4 is in the third quadrant, as it is greater than pi and less than 1.5pi, in which both the sine and the cosine are negative. Hence, considering the reference angle, we have that:
[tex](\cos{(\left(\frac{5\pi}{4}\right)}, \sin{(\left(\frac{5\pi}{4}\right)}) = (-\cos{(\left(\frac{\pi}{4}\right)}, -\sin{(\left(\frac{\pi}{4}\right)}) = \left(-\frac{\sqrt{2}}{2}, -\frac{\sqrt{2}}{2}\right)[/tex]
Hence option A is correct.

The distance, d, an object travels is represented by the equation d = rt, where r represents the average rate of speed and t represents time. Determine the units of t if d is measured in feet and r is measured in feet per second.
A.
square feet
B.
seconds
C.
feet per second
D.
feet per second squared
Answer:
B. seconds
Step-by-step explanation:
We have d=rt
means that t= [tex]\frac{d}{r}[/tex]
Given the units of each:
d: feet
r: feet/second
Replace each with its unit:
t= [tex]\frac{feet}{\frac{feet}{second} }[/tex] = [tex]\frac{feet.second}{feet}[/tex] = second
So the unit of t is seconds (option B.)
Answer:
B. secondsStep-by-step explanation:
Given
d = rtunit of d = feetunit of r = feet per secondTo Find :

Since d = rt, we can rearrange it and rewrite it as t = d/rNow substitute the units in place of d and rt = d/rt = feet/feet per secondt = (feet)/(feet)(second)⁻¹t = secondsPLEASE PLESE HELP ME WITH THIS!!!!
The new center is 5 units away from the original, hence we added 5 to the x-value.
If you notice the sides of the new triangle are twice the size of the original one, meaning that it was dilated by a scale factor of 2.
xy=10
4x+2y=30
I need help asap
Answer:
x = 25/3; y = -5/3
Step-by-step explanation:
You did well so far by multiplying both sides of the first equation by 2.
Now notice that you have -2y in the new first equation and 2y in the second equation. -2y and 2y add to 0.
Now add the equations to eliminate y.
2x - 2y = 20
(+) 4x + 2y = 30
-------------------------
6x = 50
6x/6 = 50/6
x = 50/6 = 25/3
2x - 2y = 20
2(25/3) - 2y = 20
50/3 - 2y = 60/3
-2y = 60/3 - 50/3
-2y = 10/3
-2y/2 = (10/3)/(-2)
y = -5/3
Solution: x = 25/3; y = -5/3

Tamara needs $624 for her budget every week. She works 40 hours a week.
What is the minimum amount Tamara needs to earn per hour?
Answer:
$15.6
Step-by-step explanation:
Based on the given information, it is $15.6. However, it never specified how many hours she works a day and how many days of the week she works, so we must assume it is just 624/40.
Answer:
minimum amount Tamara needs to earn per hour = 15.6.
Step-by-step explanation:
40 × x = 624
x = 624/40 = 156/10 = $15.6 per hour.

Convert the problem into split up expressions.
[tex]\frac{18}{2}(x - 6)[/tex]
Take both 6 and 18's most common factor here, 2, and divide by 2 to simplify.
[tex]\frac{18}{2} = 9\\\\\frac{6}{2} = 3[/tex]
Cancel.
18 becomes 9
6 becomes 3
The equation turns into:

note that because we, "canceled" 2, that also means it does not appear in the simplified form since it was a factor.

Answer:
UY = 16
UV = 12
XY = 20
Step-by-step explanation:
If UVWXY ~ JFGHI
then:
UV~JF
VW~FG
WX~GH
XY~HI
UY~JI
The only pair of sides that both have measures is WX and GH:
WX = 8
GH = 14
⇒ GH/WX = 14/8 = 1.75
Therefore, JFGHI is and enlargement of UVWXY by scale factor 1.75
As IJ = 28
⇒ UY = 28 ÷ 1.75 = 16
As JF = 21
⇒ UV = 21 ÷ 1.75 = 12
As HI = 35
⇒ XY = 35 ÷ 1.75 = 20

Triangle ABC and triangle DEC are
Similar
Not similar
The triangle ABC are not similar because angle E is not equal to angle B
What are similar triangles?Similar triangles have the same corresponding angle measures and proportional side lengths.
This means that similar triangles have corresponding equal angles.
And also the ratio of the corresponding sides of Similar triangles are equal.
Since angle ACB = angle DCE
angle B = 180-( 38+94)
= 180- 132
= 48°
angle D = 180-( 94+15)
= 180-109
= 71°
Therefore;
angle A is not equal to angle D and angle B is not equal to angle E, We can therefore say that triangles ABC is not similar to triangle DEC
