tan2x=___
A. tan x/1+tan^2 x
B. tan x/1-tan^2 x
C. 2tan x/1-tan^2 x
D. 2tan x/1+tan^2 x
Step-by-step explanation:
tan2x = sin2x/cos2x
we know that ,
sin2x = 2sinxcosx sin2x = 2sinxcosx cos2x = cos²x - sin²xSince, tan2x = 2sinx*cosx/cos²x- sin²x
Dividing by cos²x in numerator and denominator.
We get ,
tan2x = 2sinx/cosx / 1- sin²x/cos²x Since, we get tan2x= 2tanx/1-tan²x Option (c) is correct option. Hope it will be helpful4.80 for 16 ounces of cereal how much did i spend per ounce?

Given the value of the hypotenuse c for a 45°-45°-90° triangle, write the
equations to represent sides a and b in terms of c.
a= c/√2
b= c/√2
Since side a and b are equivalent to each other and c is the length of side a or b × √2. Dividing c by √2 gives the value of a and b.
a×√2= c
b×√2= c

The volume of a cylinder is expressed by the formula V = 3.14 × r²h, where V stands for volume, r is the radius, and h is the height of the cylinder. Suppose the volume of a cylinder is known to be 141.3 m³ and its height is 5 m. Find the radius.
Answer:
The radius is 3 meters.
Step-by-step explanation:
[tex]\pi {r}^{2} (5) = 141.3[/tex]
[tex] {r}^{2} = \frac{141.3}{5\pi} [/tex]
[tex]r = 3[/tex]

Answer:
Part A: f(4) = 2
Part B: k = -7
Step-by-step explanation:
f(4) simply means what the y-value of the graph is when x = 4.
The parabola crosses the coordinate (4,2). In other words, when x = 4, the graph equals 2.
Part B asks to solve the equation: f(4) + k = -5
We already know from Part A that f(4) = 2. So simply substitute 2 for f(4):
2 + k = - 5
Substract 2 from both sides:
k = -7

Answer my practice question. Today, the sum of Cameron's age and Christian's age is 102. 6 years ago Christian was 2 times older than Cameron.
Part A: Enter Cameron's age today.
Part B: Enter Christian's age today
Answer:
Cameron's age=48 Christain's age=54
Step-by-step explanation:
The current total age is 102.
You can do 102-6 as this will give you an idea of Christain's age as it is twice the age of Cameron.
102-6=96
96/2=48
Cameron's age=48
102-48=54
54=Christain's age

the pet store uses the data to make decisions about inventory. complete the given statement.
a customer is more likely to have 1 pet and no children than they are to have
A customer is more likely to have 1 pet and no children than they are to have 2 pets and no children.
How to find probability?
We are given a table with 3 columns titled "have children", "do not have children" and "total".
Under the row titled "1 pet", the respective probabilities are;
P(having 1 pet and children) = 38/91 = 0.4176
P(having 1 pet and no children) = 53/91 = 0.5824
Under the row titled "2 pets", the respective probabilities are;
P(having 2 pets and children) = 85/126 = 0.6746
P(having 2 pets and no children) = 41/126 = 0.3254
Under the row titled "3 or more pets", the respective probabilities are;
P(having 3 or more pets and children) = 46/118 = 0.3898
P(having 3 or more pets and no children) = 72/118 = 0.6102
The only probability that is lower than P(having 1 pet and no children) in the same way is P(having 2 pets and no children).

Pauline’s Pie’s baked 150 pies before they opened the store on Sunday. Once the store opened, they sold 30% of the pies before noon. How many pies were sold before noon?
Answer:
105
Step-by-step explanation:
First, in problems like these, you have to find 30% of 150. 30% of 150 is 45. Now, since you want to see how many pies have been sold, you do 150-45, which will give you 105.
