An angle of measure [tex]\frac{4\pi }{3}[/tex] intersects the unit circle at point ([tex]-1/2,- \frac{\sqrt{3} }{2}[/tex]). What is the exact value of tan([tex]\frac{4\pi }{3}[/tex])?
a. -1/2
b. [tex]\sqrt{3[/tex]
c. [tex]\frac{\sqrt{3} }{3}[/tex]
d. [tex]-\frac{\sqrt{3} }{2}[/tex]
Answer:
b. √3
Step-by-step explanation:
Given a point on the unit circle that represents the position of the terminal ray of an angle, the tangent of that angle is the ratio of the y-coordinate to the x-coordinate.
tan(4π/3) = y/x = (-√3/2)/(-1/2) = √3/1
tan(4π/3) = √3

A bike shop has 35 bicycles and tricycles with a total of 81 wheels. How many bicycles and how many tricycles are in the shop?
Answer:
There are 24 bicycles and 11 tricycles in the shop
Step-by-step explanation:
We can make a system of equations to find the answer:
x for bicycles and y for tricycles:
x + y = 35
2x + 3y = 81
2x because bicycles have 2 wheels, 3y because tricycles have 3 wheels, and have set the total to 81 because 81 wheels in total.
Solving, we will find that there are 24 bicycles and 11 tricycles in the shop.

OK this is quite simple. Just multiply the top and bottom, otherwise known as the numerators and denominators, by whatever is next to it. In this case, 1a is [tex]\frac{2*4}{5*4}[/tex].
That would result in [tex]\frac{8}{20}[/tex]
Hey there!
In order to multiply fractions, we should multiply the numerator of the 1st fraction by the numerator of the 2nd fraction.
Same with denominators.
Let's multiply these fractions.
2/5=2*4/5*4=8/20
2/3=2*6/3*6=12/18
1/4=1*3/4*3=3/12
3/4=3*3/4*3=9/12
now divide:
10/15=10:5/15:5=2/3
12/18=12:6/18:6=2/3
12/15=12:3/15:3=4/5
15/25=15:5/25:5=3/5
Now, simplify the following fractions:
4/6
divide the top & bottom by 2:
2/3
next:
5/10
divide the top & bottom by 5:
1/2
next
5/15
divide the top & bottom by 5:
1/3
next:
12/18
divide the top & bottom. by 6
2/3
next
5/10
divide the top & bottom by 5
1/2
next
14/16
divide the top & bottom by 2
7/8
and then last but not least
28/35
divide the top & bottom by 7
4/5
And we're done!
Hope everything is clear.
Let me know if you have any questions!

Answer:
C. Her sister grew about 0.75 inch each month.Step-by-step explanation:
Given function:
y = 0.75x + 15The function is linear and it represents:
y - current heigt of babyx - number of months passed0.75 - the slope is the monthly growth rate15 - the y-intercept, is the initial height of babyAccording the above explanation the correct answer choice is C
Slope intercept form of a line is given by y=mx+b

Area = 120 units squared
Base = 8 units
Length = ? (Include the units in your answer)
Answer:
15
Step-by-step explanation:
Okay, so we know that Base*Length=Area, so we just have to divide the area by the base, so the formula here is Area/Base=Length.
That would get us 120/8=Length,
and if we just divide 120 by 8 we get 15, so the length is 15

ANSWER PLS URGENT VERY URGENT TYSM ik its a lot of questions but id really really be grateful for the help
Step-by-step explanation:
about circle R
arc angle MP = angle MRP = 78°
angle M = angle LMP.
according to the rules of inscribed angles, LMP is half of angle LRP.
LRP + MRP = 180° because together they cover the whole LM segment (half-circle).
LRP = 180 - MRP = 180 - 78 = 102°
so, LMP = angle M = 102/2 = 61°
also circle R (with arc ULNP)
the arc ULNP = arc UL + arc LN + arc NP = 160°
due to the congruent definition of JU and MP we know that arc UL = arc NP.
and we know arc LN = arc JM = 18°.
so,
160 = 2×arc NP + 18
142 = 2×arc NP
arc NP = 71° = arc UL
now, because arc MP + arc LP = 180 (half-circle),
arc MP = 180 - arc LP = 180 - arc LN - arc NP =
= 180 - 18 - 71 = 91°
about the circle R with 2 congruent chords :
the second answer : they are equidistant from R (the center of the circle).
about circle W
arc MK + arc KL = 180° (half-circle).
and we see
arc HL = arc KL = 53°.
so,
arc MK + 53 = 180°
arc MK = 180 - 53 = 127°
about circle M
arc QTS = 204°.
therefore, arc QRS = 360 - arc QTS = 360 - 204 =
= 156° = angle QMS.
according to the rules of inscribed angles
angle QTS = QMS/2 = 156/2 = 78°
What is equilibrium, from an economic perspective? a. the theoretical price point at which demand equals supply b. a state of "all other things being equal" c. a condition in which no buying or selling is occurring d. an economy functioning without outside intervention
Answer:
A theoretical price point at which demand being equal
The theoretical price point at which demand equals supply is the correct answer.
What is equilibrium?Equilibrium is a state of balance or condition of stableness.
In economics, equilibrium is also the same, it is a condition in which prices become stable by the balance of market supply and demand.
It is a situation in which conditions cannot be changed by any economic agent strategy.
There are some properties of equilibrium
1. Consistency in the behavior of agents.
2. No economic agent has an incentive to change the behavior.
3. Equilibrium is the outcome of a few dynamic processes.
Therefore, the theoretical price point at which demand equals supply is the correct answer.

The transformation rule used are the reflection over the y-axis, dilation and vertical and horizontal shift.
Transformation of coordinatesThe translation rule for reflection of the coordinate point (x, y) across the y-axis is (-x, y)
The rule (x, y) → (0.5x, 0.5y) shows a dilation of the coordinate (x, y) by a factor of 0.5. It will reduce the size of the resulting figure since the factor is less than 1.
