Considering only the values of α for which tanαcos(2α) is defined, which of the following expressions is equivalent to tanαcos(2α)?
The equivalent expression at the point where it is undefined is ∞
Undefined expressionGiven the trigonometry expression
tanαcos(2α)
From trigonometry identity;
tanα = sinα/cosα
The expression above will become:
tanαcos(2α) = sinαcos(2α)/cosα
The function is undefined at the point where cosα = 0
cosα = 0
α = arccos(0)
α = 90degrees
Substitute α = 90degrees into the expression;
tanαcos(2α) = tan 90 cos(180)
tanαcos(2α) = ∞
Hence the equivalent expression at the point where it is undefined is ∞

Test Prep There are 80 marbles in a bag. If 30% of the marbles are green, how many marbles are not green
Hey there!
Step 1: Calculate percentage
Since 30% of the marbles are green
=> 80 × 30/100
=> 8 × 30/10
=> 240/10
=> 24
So, 24 of the marbles are green
Step 2: Substract 24 from 80
=> 80 - 24
=> 56
Therefore, 56 marbles are not green

The lifespans of a particular brand of graphing calculator are approximately normally distributed with a mean of 620 days from the purchase date and a standard deviation of 82 days. They will provide a warranty that guarantees a replacement if the calculator stops working within the specified time frame and are trying to decide what time frame to use.
a. If the company sets the warranty at a year and a half (say 540 days), what proportion of calculators will they have to replace ?
b. The company doesn’t not want to replace more than 1% of the calculators they sell. What length of time should the set for the warranty?
c. The company would like to set the warranty for 540 days, and still replace no more than 1% of the calculators sold. Increasing the average life of the calculators is too expensive, but they think they reduce the standard deviation of the lifespans. What standard deviation of lifespans would be needed to make this happen ?

Caitlin is designing a railing for a set of stairs. The railing will begin at a height of 36 inches and follow the slant of the stairs, which decreases 9 inches for every 12 horizontal inches.
A drawing of the side view of a set of 4 stairs. There are lines drawn to show a railing that is at the highest point of the stairs and labeled 36 inches.
Which function can represent the height, y, of the railing in inches according to the horizontal distance in inches, x, from the top of the stairs?
Answer:
Since we are given that the railing will begin at a height of 36 inches and follow the slant of the stairs, which decreases 9 vertical inches for every 12 horizontal inches.
Thus the rate of change :
Rate of change represents the slope of line.
Since we are given that height, y, of the railing in inches according to the horizontal distance in inches, x, from the top of the stairs
And the initial height of the railing was 36 inches .
So,the function which would represent the situation can be shown using equation of line :
y = mx+c
So
c = 36 inches
So, the function :
Hence The function which can represent the height, y, of the railing in inches according to the horizontal distance in inches, x, from the top of the stairs :

A , B and C form a triangle where ∠ B A C = 90 ∘ . A B = 0.5 mm and B C = 15.4 mm. Find the length of A C , giving your answer rounded to 1 decimal place.
Answer:
15•4 mm
Step-by-step explanation:
using sine rule
a÷ sinA=c ÷sinC
15•4÷sin90=0•5÷sinC
sinC =0•5 × sin90 ÷ 15•4
C =1•9°
A+B+C= 180
90+B+1•9=180
B= 88•2°
b÷sinB = a÷sinA
b÷sin88•2= 15•4÷sin90
b=sin88•2 ×15•4 ÷sin90
b =15•39
to 1 dp
b =15•4 mm

Answer:
y= [tex]\frac{72}{5}[/tex] or 14.4
Step-by-step explanation:
[tex]\frac{5}{6}y = 12\\[/tex]
Multiply both sides by 6/5, the reciprocal of 5/6.
[tex]y = 12 * (\frac{6}{5} )[/tex]
Express 12 x (6/5) as a single fraction.
[tex]y = \frac{12 * 6}{5}[/tex]
Multiply 12 and 6 to get 72.
[tex]y = \frac{72}{5}[/tex]
what is the difference between a bisector and a perpendicular bisector?
Answer:
In Geometry, “Bisector” is a line that divides the line into two different or equal parts. It is applied to the line segments and angles.
A perpendicular bisector is a line that bisects another line segment at a right angle, through the intersection point. Thus, we can say, a perpendicular bisector always divides a line segment through its midpoint. The term bisect itself means dividing equally or uniformly.

Frank and Lisa are analyzing the chart, which shows the speed at which light travels through different media. A 2 column table with 4 rows with the column on the left labeled medium with entries water, air, glass, diamond. The column on the right is labeled speed of light in meters per second and are all times 10 Superscript 8 Baseline with entries 2. 25, 2. 99, 1. 97, 1. 24. Frank says that light travels through diamond with the greatest frequency. Lisa says that light travels through air with the greatest frequency. Which best describes the accuracy of these statements? Frank is correct because light travels through diamond at the slowest speed, and speed and frequency have an inverse relationship. Lisa is correct because light travels through air at the fastest speed, and speed and frequency have a direct relationship. Neither person is correct because light does not change frequency when it travels through different media. Both people are correct because light has both an inverse and a direct relationship with frequency, depending on the media.
The correct answer is
c) Neither person is correct because light does not change frequency when it travels through different media

A. Using the distributive property
B. Combining like terms
ОООО
O C. Dividing both sides by 10 to isolate the variable
D. Using the commutative property
While solving the equation 5(2x - 8) = 20, we used the distributive, combining like terms and Division property but commutative property is not part of the solution process, option D is correct.
The given equation is 5(2x - 8) = 20.
Using the distributive property, we get:
10x-40=20
Add 40 from both sides:
10x-40+40=20+40
Combining like terms:
10x=60
Divide both sides by 10 to isolate the variable:
10x/10=60/10
x=5
Hence, for solving the equation we have not used the commutative property. option D is correct.

The area of circle A is 45 square units. Circle A and circle B are related by a scale factor of 4 3/4
Complete the following statements:
The area of circle B is 45 x ______
The ratio of the area of circle A to the area of circle B is _____
Both circles are similar, therefore:
The area of circle B is: 33.75 sq. units.
The ratio of the area of circle A to that of circle B = 9/16 = 0.75
What is the Area of Similar Circles?The ratio of the area of similar circles = ratio of the square of their scale factor.
Given the following:
Area of circle A = 45 sq. units.
Scale factor = 3/4
The area of circle B = 45 × 3/4 = 33.75 sq. units.
