Given sin x = 8/10, 90° <x< 180° and tan y = -12/5, 270° ≤y≤ 360°. Without finding the values for angle x and y, determine cos x cos y + sin x sin y / tan x - tan y.
Answer:[tex]-\frac{189}{208}[/tex]
Step-by-step explanation:
Given
[tex]\sin x=\frac{8}{10}[/tex]
x lies in the second quadrant where sin and cosec is positive and rest trigonometric functions are negative
so, [tex]\cos x=-\sqrt{1-sin ^2 x}\\\cos x=-\sqrt{1-(\frac{8}{10})^2}=-\sqrt{\frac{36}{100}}\\\cos x=-\sqrt{\frac{6}{10}}[/tex]
[tex]\tan x=\frac{\sin x}{\cos x}=-\frac{4}{3}[/tex]
similarly, [tex]\tan y=-\frac{12}{5}[/tex]
Also, y lies in 4 th Quadrant where cos and sec is positive and rest trigonometric functions are negative
[tex]\sec y=\sqrt{1+\tan ^2y}=\sqrt{1+(-\frac{12}{5})^2}\\\sec y=\frac{13}{5}\\\cos y=\frac{5}{13}\\\sin y =\frac{\tan y}{\cos y}=-\frac{12}{13}[/tex]
Now putting the values
=[tex]\dfrac{\cos x \cos y+\sin x\sin y}{\tan x-\tan y}=\dfrac{(\frac{-6}{10})(\frac{5}{13})+(\frac{8}{10})(\frac{-12}{13})}{(\frac{-8}{6})-(\frac{-12}{5})}\\\dfrac{\cos x \cos y+\sin x\sin y}{\tan x-\tan y}=\dfrac{\frac{-126}{130}}{\frac{16}{15}}=-\frac{189}{208}[/tex]

Write the ratio of stars to squares in all 3 forms (remember to simplify).
Answer:
Step-by-step explanation:
From the picture attached,
Number of stars = 3
Number of squares = 5
Ratio of stars to squares can be written in three forms as,
Number of stars to number of square = 3 to 5
Number of stars : Number of squares = 3 : 5
[tex]\frac{\text{Number of stars}}{\text{Number of squares}}=\frac{3}{5}[/tex]

Is the binomial a factor of the polynomial function?
f(x) = x^3 + 3x^2 – 25x – 75
Select Yes or No for each binomial.
Answer:
Yes, the binomial is a factor of the polynomial function.
Step-by-step explanation:
Consider the given polynomial.
Factor out the common term [tex]x^2[/tex] from the first two terms and [tex]-25[/tex] from the last two terms.
[tex]x^3 + 3x^2 -25x-75=x^2(x+3)-25(x+3)[/tex]
Factor out the polynomial.
[tex]x^2(x+3)-25(x+3)=(x+3)(x^2-25)[/tex]
Further, simplify.
[tex](x+3)(x^2-25)=(x+3)(x+5)(x-5)[/tex]
Therefore, [tex]x^3 + 3x^2 -25x-75=(x+3)(x+5)(x-5)[/tex]
A binomial factor is simply a factor with two terms, like (x - a).
Hence, the given polynomial function is binomial as it contains the factor with two terms, like (x - a).
Answer:
Yes No
Yes(x+3) No (x−1)
Yes – (x−5)

Find the distance between the two points and simplest rational form (3,-4) (6,-7))
Answer:
[tex]D = 3\sqrt{2}[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (3,-4)[/tex]
[tex](x_2,y_2) = (6,-7)[/tex]
Required
Determine the distance between the two points
Distance (D) is calculated as:
[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Substitute values for x's and y's
[tex]D = \sqrt{(6 - 3)^2 + (-7 - (-4))^2}[/tex]
[tex]D = \sqrt{(6 - 3)^2 + (-7 +4)^2}[/tex]
[tex]D = \sqrt{(3)^2 + (-3)^2}[/tex]
[tex]D = \sqrt{9+9}[/tex]
[tex]D = \sqrt{18}[/tex]
Express as 9 * 2
[tex]D = \sqrt{9*2}[/tex]
Split:
[tex]D = \sqrt{9}*\sqrt{2}[/tex]
[tex]D = 3*\sqrt{2}[/tex]
[tex]D = 3\sqrt{2}[/tex]

The points (10,16) and (30,48) form a proportional relationship. Find the slope of the line through the points. Then use the slope to graph the line.
Answer:
1.6
Step-by-step explanation:
Step one:
given data
x1=10
y1=16
x2=30
y2=48
Required
The slope of the given points
Step two:
The expression for the slope is
S= change in y/change in x
S= y2-y1/x2-x1
S= 48-16/30-10
S=32/20
S=1.6
Hence the slope is 1.6

It takes Maria 10 hours to pick forty bushels of apples. Kayla can pick the same
amount in 12 hours. How long will it take if they work together? Round your answer
to the nearest tenths place.
Answer:
5.3
Step-by-step explanation:
It will take a time 0f 5.5 hours to pick 40 bushels of apple if they worked together.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Suppose we have two ratio p : q and r : s.
If both these ratios are proportional, then we can write it as p: q : : r : s.
This is same as p : q = r : s or p/q = r/s
Given that,
Amount of bushels picked by Maria in 10 hours = 40
Amount of bushels picked by Maria in 1 hour = 40/10 = 4
Amount of bushels picked by Kayla in 12 hours = 40
Amount of bushels picked by Maria in 1 hour = 40/12 = 3.333
Amount of apple picked by both Maria and Kayla in 1 hour if they worked together = 4 + 3.333 = 7.333
Let x be the time taken to pick 40 bushels of apple by both.
Using proportional concept,
x / 40 = 1 / 7.333
x = 40 / 7.333
x = 5.4548 ≈ 5.5 hours
Time taken if they both worked together is 5.5 hours.
