Step-by-step explanation:
Write [tex]cot^{2} x (1+tan^{2} x)[/tex] Then simplify the expression so no quotients appear
Step-by-step explanation:
From Trig
1 + tan²x = Sec²x
Also
Sec²x = 1/cos²x
Now
Cot²x = 1/tan²x = cos²x/sin²x
Putting all together
Cot²x(1+tan²x)
= Cot²x(sec²x)
= cos²x/sin²x(1/cos²x)
cos²x on the numerator and that one the denominator cancels out
we have
= 1/sin²x
From Trig
1/sin²x = cosec²x
So Our Answer = cosec²x.

factor of 180?
Answer:
36
We determined above that the greatest perfect square from the list of all factors of 180 is 36.
Answer:
36
Step-by-step explanation:
You list all factors of 180 and then find a number that is a perfect square
1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, and 180.
As you can see, 36 is the greatest perfect square
The square root = 6

The weight of oranges growing in an orchard is normally distributed with a mean weight of 3.5 oz. and a standard deviation of 0.5 oz. Using the empirical rule, determine what interval would represent weights of the middle 68% of all oranges from this orchard.
Answer:
(3 oz ; 4oz)
Step-by-step explanation:
Given that :
Mean = 3.5 oz
Standard deviation = 0.5 oz
According to the empirical rule ; 68% is 1 standard deviation from the mean.
Hence, the interval that would represent the middle 68% will be:
(3.5 oz - 0.5 oz) ; (3.5 oz + 0.5oz)
(3 oz ; 4oz)

23 travelers forest 63 piles of plantains containing the same number of plantains and a remaining pile containing 7 plantains. They divided the plantains equally. What is the least number of plantains that each traveler got?
Answer:
14 plantains
Step-by-step explanation:
Given
[tex]x \to[/tex] plantain in a pile
[tex]y \to[/tex] plantain received by each
[tex]n = 23[/tex] travelers
Required
The least value of y
Note that:
- There are x plantains in 1 pile, so there will be 63x in 63 piles
- The number of plantains shared is: 7 to 63x (7 represents the single plantain)
- 1 traveler gets y plantains, so 23y will receive 7 + 63x plantains
So, the equation is:
[tex]23y = 7 + 63x[/tex]
Make y the subject
[tex]y = \frac{7 + 63x}{23}[/tex]
The values of x and y must be integer and these values must be greater than 0.
Using trial by error method, we test the values of x starting from 1;
So, we have:
[tex]x = 1 \to y = \frac{7 + 63 * 1}{23} = \frac{70}{23} = 3.04[/tex]
[tex]x = 2 \to y = \frac{7 + 63 * 2}{23} = \frac{133}{23} = 5.78[/tex]
[tex]x = 3 \to y = \frac{7 + 63 * 3}{23} = \frac{133}{23} = 8.52[/tex]
[tex]x = 4 \to y = \frac{7 + 63 * 4}{23} = \frac{259}{23} = 11.26[/tex]
[tex]x = 5 \to y = \frac{7 + 63 * 5}{23} = \frac{322}{23} = 14[/tex]
So, the smallest values of x and y that satisfy the equation is:
[tex](x,y)=(5,14)[/tex]
Hence, the least number of plantain each traveler got is 14
Which equations are true? Choose all that apply.
A. 15^0=15
B. (8^3) (8^6)= 8^9
C. 5^2 = 1/5-3
D. (6^5)^3 = 6^15
E. 3^7/3^9 = 3^-2
Answer:
B, D, E
Step-by-step explanation:
A) anything to the zero power equals one
B) when bases are the same and being multiplied, add their exponents
C) 5² = 25
D) when parentheses separate exponents, they should be multiplied
E) when bases are the same being divided, subtract their exponents
60% expressed as a ration is StartFraction 60 Over 100 EndFraction. What is this as a fraction in its reduced form?
Answer:
3/5
Step-by-step explanation:
60% means 60 out of 100. For example if you get 60 marks in an exam of 100 marks. This means you got 60% marks.
Which is 60/100. This fraction can further be reduced to 6/10 [divide both numerator and denominator by 10)
6/10 = 3/5 [divide both numerator and denominator by 2)
So, the reduced form of 60% =3/5

s t are positive integers
(X +S) (x-t) is expanded - Simplified
The
answer
is x² + Kx-40 where K is a positive integer
work out the
out the smallest possible value of K
Given:
The expanded form of [tex](x+s)(x-t)[/tex] is [tex]x^2+Kx-40[/tex].
Where, s, t, K are positive integers.
To find:
The smallest possible value of K.
Solution:
The expanded form of [tex](x+s)(x-t)[/tex] is [tex]x^2+Kx-40[/tex]. It means,
[tex](x+s)(x-t)=x^2+Kx-40[/tex]
[tex]x^2-tx+sx-st=x^2+Kx-40[/tex]
[tex]x^2+(s-t)x-st=x^2+Kx-40[/tex]
On comping both sides, we get
[tex]K=s-t[/tex] ...(i)
K is a positive integer if s>t.
And
[tex]st=40[/tex]
The factor pairs of 40 are (1,40), (2,20), (4,10), (5,8), (8,5), (10,4), (20,2) and (40,1).
Since s>t, therefore the possible values for (s,t) are (8,5), (10,4), (20,2) and (40,1).
Using (i), find the value of K for each factor pair.
[tex]K=8-5=3[/tex]
[tex]K=10-4=6[/tex]
[tex]K=20-2=18[/tex]
[tex]K=40-1=39[/tex]
Therefore, the smallest possible value of K is 3.

Find the angle of xyz
Give your answer to 1 decimal place.
Answer:
The value of sine of angle XYZ is equal to 0.96.
Step-by-step explanation:
Given that,
Base, b = 4 cm
Height, h = 13 cm
We need to find the sinY.
Using Pythagoras theorem,
YZ² = XY² + XZ²
YZ² = 4² + 13²
YZ = 13.60 cm
Using trigonometry,
[tex]\sin Y=\dfrac{13}{13.60}\\\\\sin Y=0.96[/tex]
So, the value of sine of angle XYZ is equal to 0.96.
