Answer:
5√3/3
Step-by-step explanation:
To get the shorter leg of the triangle, we have to divide the longer leg by √3: 5/√3
To solve, multiply by √3/√3: 5/√3 * √3/√3 = 5√3/√9 = 5√3/3
Which expression is equivalent to (tangent (startfraction theta over 2 endfraction) ) (negative sine theta)?

b) -1/3
c) (-1.5,0)
d) 3
e) 4
f) (0,4)
g) -3
h) 1/3
Answer:
D
Step-by-step explanation:
you can use the slope intercept form: y = mx + b.
y = y cooordinate
m = slope
x = x coordinate
b = y intercept
the y intercept is 4.
the point (1, 7) is what we're going to use.
so the new equation is
7 = m + 4 (it would be 1m, but i rewrote it to be mathmatically correct)
subtract 4 from both sides, you should have 3 = m.
the slope is 3

For parallelogram RYFU, let N be the intersection point of the diagonals. Let RF = 7x-11 and NF = 2x+2. Find the measurement of EVERYTHING that you know, if possible.
The diagonals of parallelogram RYUF each measure 24 units.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Diagonals of parallelogram are congruent and bisect each other.
Point N is the intersection point of the diagonals of parallelogram RYFU. Hence, RF is the diagonal and N is the midpoint:
2 * NF = RF
2(2x + 2) = 7x - 11
x = 5
RF = 7(5) - 11 = 24

A circular sheet of paper of radius 6 inches is cut into 3 equal sectors, and each sector is formed into a cone with no overlap. What is the height in inches of the cone
The height of the cone is 4√2 inches.
The circumference of the base of each cone will be the arc length of one of the sectors
= 2 [tex]\pi[/tex] (6) / 3
= 4 [tex]\pi[/tex] inches
So, the radius, r, of each cone (in inches) is given by :
4pi = 2 [tex]\pi[/tex] * r
4 = 2r
2 = r
Using the Pythagorean Theorem, the cone height, h, is given by :
h = √[ slant height^2 - radius^2 ]
= √ [ 6^2 - 2^2 ]
= √32
= 4√2 inches

He is offered a discount for the first five months. after this period, his rate increases by $8.50 per month. his total cost at the end of the year is $245.50. paul wrote the following equation represent his plan. 5x + 7(x + 8.50) = 245.50 part a: how much, in total, will paul pay during the five discounted months of his plan? (1 point
The first five months Paul paid and in the next seven months he paid 24.
What is a Discount ?Discounts are defined as lowered prices or the sale of an item for less than it would typically cost. The fundamental formula for calculating a discount is to multiply the original price by the given percentage rate in decimal form. We must deduct the discount from the original price to determine the item's sale price. A discount is an amount that is subtracted from the regular price of an item.
Paul represent his plan in the form of equation:
[tex]5 x+7(x+8.50)=245.50[/tex]
Where x is an amount for the first [tex]5[/tex] months that is paid by Paul after the discount and [tex](x+8.50)[/tex] is an amount for the next [tex]7[/tex] month after discount.
[tex]&\Rightarrow \quad 5 x+7 x+59.50=245.50 \\&\Rightarrow \quad 12 x=186 \\&\Rightarrow \quad x=\frac{186}{12} \\&\Rightarrow \quad x=15.50\end{aligned}[/tex]
For the next 7 month:
[tex](x+8.50)=(15.50+8.50)=\$ 24[/tex]

O (-1,-1)
O (1,0)
O (-1,0)
O (0,-.369)

Answer:
(1, 0 )
Step-by-step explanation:
using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex] , then
y = [tex]log_{3}[/tex] (x + 2) - 1
to find the zero let y = 0 , that is
[tex]log_{3}[/tex] (x + 2) - 1 = 0 ( add 1 to both sides )
[tex]log_{3}[/tex] (x + 2) = 1 , then

x = 1
the zero is (1, 0 )

What are the coordinates of P'?
P’(1, 2)

P'(4, 4)
The resulting point by considering that P(x, y) = (6, - 1) and P'(x, y) = P(x, y) + (- 5, - 2) is equal to the coordinates P'(x, y) = (1, - 3). (Right choice: C)
How to determined a resulting point by translation
In this question we need to determine the new location of a point by using a translation formula. Translations are rigid transformations in which a point is translated on a Cartesian plane. We have the following formula:
P'(x, y) = P(x, y) + (- 5, - 2) (1)
Where:
P(x, y) - Original pointP'(x, y) - Resulting pointIf we know that P(x, y) = (6, - 1), then the resulting point is:
P'(x, y) = (6, - 1) + (- 5, - 2)
P'(x, y) = (1, - 3)
The resulting point by considering that P(x, y) = (6, - 1) and P'(x, y) = P(x, y) + (- 5, - 2) is equal to the coordinates P'(x, y) = (1, - 3). (Right choice: C)

Marjorie and Blaine make chairs together. Marjorie builds the seat and Blaine independently sews the cushions to rest on top of them. It takes Marjorie 1 1/2hours to build the seat and Blaine 40 minutes to sew the cushion. How long would it take for them to make 10 chairs?
Making 10 chairs would take Marjorie and Blaine 21 hours and 40 minutes.
How long does it take to make 10 chairs?The total time it takes Marjorie and Blaine to perform their respective tasks in building a chair is multiplied by 10 chairs, respectively. This time is known as their speed.
The resulting figures are summed to get the total time.
Data and Calculations:The total time it takes Marjorie to build a chair is 15 hours (1.5 hours x 10)
The total time it takes Baline to sew cushions per chair is 400 minutes (40 x 10) or 6 hours and 40 minutes.
Therefore, the total time to build 10 chairs is 21 hours, 40 minutes (15 hours + 6 hours and 40 minutes).

The coordinates of the vertices of the translated triangle are A'(x, y) = (1, 8), B'(x, y) = (2, 6) and C'(x, y) = (- 1, 6).
How to translate a triangle by transformation rules
Graphically speaking, triangles can be generated by knowing its three vertices. In this question we must apply a kind of rigid transformation known as translation, whose formula is:
P'(x, y) = P(x, y) + T(x, y) (1)
Where:
P(x, y) - Original pointP'(x, y) - Resulting pointT(x, y) - Translation vectorIf we know that A(x, y) = (3, 4), B(x, y) = (4, 2), C(x, y) = (1, 2) and T(x, y) = (-2, 4), then the new coordinates are:
A'(x, y) = (3, 4) + (- 2, 4)
A'(x, y) = (1, 8)
B'(x, y) = (4, 2) + (- 2, 4)
B'(x, y) = (2, 6)
C'(x, y) = (1, 2) + (- 2, 4)
C'(x, y) = (- 1, 6)
Remark
The statement presents typing mistakes, correct form is:
Translate the triangle with the vector <- 2, 4>, then enter the new coordinates:

your answer. (5 points)
The cyclist that will come to stop first when the brake is applied, is the cyclist with lesser mass which is Cyclist B because of its lesser inertia.
What is law of inertia?
The law of inertia states that an object at rest or uniform motion in a straight line will continue in that path unless acted upon by an external force.
Inertia depends on mass of the object, the more massive an object is, the more reluctant it will be to stop and vice versa.
Thus, the cyclist that will come to stop first when the brake is applied, is the cyclist with lesser mass which is Cyclist B because of its lesser inertia.
