What is the answer to this question?
Answers
Answer: Choice A) 4, 3, 5, 1, 2
=====================================================
Explanation:
Since tan(x) = sin(x)/cos(x) is a known and widely used trig identity, this must mean step 4 goes first.
The answer is between choice A and choice B.
The question is now: What is the correct second step?
It's either step 3 (choice A) or step 5 (choice B)
It turns out that step 3 is the correct statement after step 4. The sin(2x) breaks up into 2sin(x)cos(x), while the cos(2x) breaks up into cos^2(x)-sin^2(x). There are three different variations for the cos(2x) and this just happens to be one of them.
So we can rule out choice B and go with choice A as the final answer.

(1-sin2A)(1+cot2A)=cot2A
Answers
This isn't an identity, so I assume you have to solve the equation.
(1 - sin(2A)) (1 + cot(2A)) = cot(2A)
1 - sin(2A) + cot(2A) - sin(2A) cot(2A) = cot(2A)
1 - sin(2A) - cos(2A) = 0
sin(2A) + cos(2A) = 1
Multiply both sides by 1/√2, which we want to do because cos(π/4) = sin(π/4) = 1/√2. This gives
cos(π/4) sin(2A) + sin(π/4) cos(2A) = 1/√2
Then condense the left side as
sin(2A + π/4) = 1/√2
2A + π/4 = sin⁻¹(1/√2) + 2nπ or 2A + π/4 = π - sin⁻¹(1/√2) + 2nπ
(where n is any integer)
2A + π/4 = π/4 + 2nπ or 2A + π/4 = 3π/4 + 2nπ
2A = 2nπ or 2A = π/2 + 2nπ
A = nπ or A = π/4 + nπ

Whitney was visiting Big Bend Ranch
State Park. At the entrance, she saw a
map of the park. The legend stated
that 1.5 inches on the map represents
20 feet in the park. On the map, how
many inches would represent 60
actual feet?
Answers
Answer:
4.5 inches on the map would represent 60 actual feet.
Step-by-step explanation:
Given that:
1.5 inches on map represents 20 feet in the park.
x be the inches on map that represents 60 feet in the park.
Ratio of distance on map to actual distance :: Ratio of distance on map to actual distance
1.5 : 20 :: x : 60
Product of mean = Product of extreme
20*x = 1.5*60
20x = 90
Dividing both sides by 20
[tex]\frac{20x}{20}=\frac{90}{20}\\x=4.5[/tex]
Hence,
4.5 inches on the map would represent 60 actual feet.

A beach ball is inflated so its diameter increases from 12 inches to 12.5 inches. Given that the formula for the volume of a sphere is V=4/3π,r^3 the change in the volume of the beach ball using differentials is approximately.
a. 367π cubic inches.
b. 727π cubic inches.
c. 1447π cubic inches.
d. 288.7π cubic inches.
Answers
Answer:
V = 36π cubic inches.
Step-by-step explanation:
Given that:
The volume of the sphere is [tex]V = \dfrac{4}{3} \pi r^3[/tex]
If the diameter is represented by P.
Then P = 2r
and r = P/2
∴
[tex]V = \dfrac{4}{3} \pi ( \dfrac{P}{2})^3[/tex]
By differentiating both sides;
[tex]dV = \dfrac{4}{3} \pi \times 3 ( \dfrac{P}{2})^2 \times \dfrac{1}{2} \times dP[/tex]
[tex]dV = \dfrac{1}{2} \pi P^2 \ dP[/tex]
where;
P = 12
dP = 12.5 - 12
dP = 0.5
Then;
[tex]\dfrac{1}{2} \pi ( 12)^2 \times 0.5[/tex]
= 36π
Thus, the volume is V = 36π cubic inches.
The given function has a domain of {-4, -2, 0, 2, 4} Find the function's range.
f(x) = 2x - 1
{-4, -2, 0, 2, 4}
{9, 5, 1, 3, 7}
{-9, -5, -4, -2, -1, 0, 2, 3, 4, 7}
{-9, -5, -1, 3, 7}
Answers
Answer:
The range of the function will be: {-9, -5, -1, 3, 7}
Step-by-step explanation:
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.Given the function
f(x) = 2x - 1
Given that the domain of the function is:
{-4, -2, 0, 2, 4}
Putting x=-4
f(x) = 2x - 1
f(-4)= 2(-4)-1=-8-1=-9
Thus,
at x=-4, y = -9
Putting x=-2
f(x) = 2x - 1
f(-2)= 2(-2)-1=-4-1=-5
Thus,
at x=-2, y = -5
Putting x=0
f(x) = 2x - 1
f(0)= 2(0)-1=0-1=-1
Thus,
at x=-2, y = -1
Putting x=2
f(x) = 2x - 1
f(2)= 2(2)-1=4-1=3
Thus,
at x=-2, y = 3
Putting x=4
f(x) = 2x - 1
f(4)= 2(4)-1=8-1=7
Thus,
at x=-2, y = 7
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.
Thus, the range of the function will have all the y values correspond to all the x values for which the function is defined.
Thus, the range of the function will be: {-9, -5, -1, 3, 7}

What is the partial product of 2.3 x 2.6?
Answers
The partial product of 2.3 x 2.6 is 5.98
What is partial product?When we multiply a multiplicand by one digit of a multiplier that has more than one digit, the product is known as a partial product.
The given term is,
2.3 x 2.6
To find the partial product of this number, use partial product method
2.3 can be written as = 2 + 0.3
2.6 can be written as = 2 + 0.6
Partial product = 2×2 + 2×0.6 + 2×0.3+ 0.3×0.6
= 4 + 1.2 + 0.6 + 0.18
= 5.98
The partial product is 5.98.

Answer:
4= 3(y+3) - 2y (substitute the given x-value into the equation to solve for y)
4= 3y+9-2y (use the distributive property)
4=y+9 (combine like terms)
y= -5 (subtract 9 from both sides to isolate the y-term)
plug it in
x= (-5)+3
x=-2

plug x=y+3 into the second equation
4= 3(y+3) -2y
solve for y
4= 3y+9 -2y
4=y+9
y= -5
plug y= -5 into either equation to get x
