If sin theta= 4/5 and theta is in quadrant 2, the value of cot theta is . if necessary, use the slash mark ( / ) for a fraction bar.
Answers
a^2 + 4^2 = 5^2
a = 3
cos = -3/5
so tan would be -4/3
and then cot would be -3/4
i think that’s right ^
If sin θ= 4/5 and theta is in quadrant 2, the cot θ would be -3/4.
Which trigonometric functions are positive in which quadrant?
In first quadrant (0 < θ < π/2), all six trigonometric functions are positive.
In second quadrant(π/2 < θ < π), only sin and cosec are positive.
In the third quadrant (π < θ < 3π/2), only tangent and cotangent are positive.
In fourth (3π/2 < θ < 2π = 0), only cos and sec are positive.
Given information; If sin θ= 4/5 and theta is in quadrant 2, we need to find the value of cot theta.
Since it’s in second quadrant, cos is going to be negative.
So, a^2 + 4^2 = 5^2
a^2 + 16 = 25
a^2 = 25 - 16 = 9
a = 3
therefore, we can conclude that cos θ = base / hypotenuse
cos θ =-3/5
Also, tan θ would be -4/3 and then cot θ would be -3/4.

What is the RANGE of the following graph?
y=-x2- 2x - 5
2
Answers
Answer:
See below in bold.
Step-by-step explanation:
y = -x^2 - 2x - 5
Convert to vertex form:
y = -(x^2 + 2x) - 5
y = - [(x + 1)^2 - 1] - 5
y = -(x + 1)^2 + 1 - 5
y = -(x + 1)^2 - 4
So the vertex of the graph is at (-1 , -4) and it is a maximum because the coefficient of x^2 is negative.
So the range is all values of f(x) up to and including -4.
In interval notation this is (-∞, -4].

Complete question is;
A fair coin should land showing tails with a relative frequency of 50% in a long series of flips. Felicia read
that spinning-rather than flipping-a US penny on a flat surface is not fair, and that spinning a penny
makes it more likely to land showing tails. She spun her own penny 100 times to test this, and the penny

What are appropriate hypotheses for Connor's significance test?
A. H_0 : p = 50% H_1 : p > 60%
B. H_0: p = 50% H_1: p > 50%
C. H_0: p = 50% H_1: p < 50%
D. H_0 : p = 60% H_1 : p < 60%
Answer:
Option B is correct
Step-by-step explanation:
From the question it is clear that;
The population proportion is 50% because it is not associated with any sample size.
However, the sample size is 100 and the sample proportion from this 100 is 60%.
But we don't define our hypothesis based on the sample proportion.
Now we want to find the probability that spinning a penny makes it more likely to land showing tails.
Thus we define the hypothesis as;
Null hypothesis; H0 : p=50%
Alternative hypothesis; H1 : p>50%

Barton has 4 strawberries and Ona has 8. If they want to redistribute their strawberries so they each have an equal number, how many strawberries should Ona give to Barton? There are a total of strawberries. There are a total of people. The expression to find the mean, or balance point, is . should give 2 strawberries to for the number of strawberries to be balanced.
Answers
Answer:
2 strawberries
Step-by-step explanation:
Given that:
Number of strawberries :
Ona has 8
Barton has 4
For both Ona and Barton to have the same Nunber of strawberries :
(Ona + Barton) /2 = (8 + 4) / 2 = 12 /2 = 6
That means both Ona and Barton will have 6 strawberries each
Hence,
Barton who has 4 strawberries needs 2 more while Ona who has 8 will give out 2
Hence, Ona should give two strawberries to Barton.
Answer:
total strawberries 12
total 2 people
expression to find the mean 12/2
ona should give barton 2 strawberries so the number balance's out

(x, y) + (x+10, y+7)
(x, y) + (x-10, y-7)
Answers
Answer:
Option A
Step-by-step explanation:
Coordinates of the given points A and A',
A → (-6, -2)
A' → (-2, 1)
Rule for the translation of point A to A',
A(-6, -2) → A'(-6+h, -2+k)
Since, coordinates of A' are (-2, 1)
Therefore, -6 + h = -2
h = 6 - 2 = 4
And (-2 + k) = 1
k = 3
Therefore, rule for the translation will be,
(x, y) → (x + 4, y + 3)
Option A will be the answer.

What is the Greatest Common Denominator or factor between 244 & 48
Answers
Answer:
GCF = 4.
Step-by-step explanation:
Find the prime factors:
48 = 2*2*2*2*3
244 = 2*2*61
The greatest common factor, the GCF) (picking out the common values) =
2 *2 = 4.
A really clever way of finding the GCF of 2 numbers is Euclid's algorithm. It can be used for very large numbers where it would be time consuming and/or rather difficult to find prime factors:
Given two whole numbers where a is greater than b, do the division a ÷ b = c with remainder R.
Replace a with b, replace b with R and repeat the division.
Repeat step 2 until R=0.
When R=0, the divisor, b, in the last equation is the greatest common factor.
So applying this to our problem:
244 / 48 = 5 remainder 4
Replacing a (244) with 48 and b (48) with R (4):-
48/4 = 12 remainder 0.
So the GCF is 4.

What is a number system?A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set in a consistent manner using digits or other symbols. In different numeral systems, the same sequence of symbols can represent different numbers.
Given that the sum of two numbers is 48. if the smaller number is subtracted from the larger the difference is 12. The two numbers will be calculated as,
x + y = 48
x - y = 12
________
2x = 60
x = 30
y = 30 - 12
y = 18
Therefore, the value of the larger number is 30 and the value of the smaller number is 18.
