Given sin theta=1/3 and 0 < theta< π/2; find tan 2 theta.
Answers
Answer:
tan2θ = 4√2/7
Step-by-step explanation:
Given sin theta=1/3 and 0 < theta< π/+
Required
tan 2 theta
tan2 theta = 2tanθ/1-tan²θ
Get tan θ
sinθ = opp/hyp
adj = √3²-1²²
adj = √9-1
adj = √8
tanθ = opp/adj = 1/2√2
tan2 theta = 2(1/2√2/1-(1/2√2)²
tan2θ = 1/√2/1-1/8
tan2θ = 1/√2/7/8
tan2θ = 8/7√2
Rationalize
tan2θ = 8√2/14
tan2θ = 4√2/7

Two experiments were carried out to find the relationship between the variables x and y. Both
experiments showed that the relationship between x and y is in accordance to 3(9^x) = 27^y and log2 y = 2 + log2 (x - 2). Find the value of x and y that satisfy both experiments.
Answers
Answer:
X=5/2 , y=2
Step-by-step explanation:
Sorry if I'm not correct
F4 ke?
y = 2
Explanation:
3(9^x) = 27^y
3(3^2x) = 3^3y
3^(2x + 1) = 3^3y
2x + 1 = 3y
2x - 3y = -1, first equation
log2 y = 2 + log2 (x - 2)
log2 y = log2 (2^2) + log2 (x - 2)
log2 y = log2 (2^2 x [x - 2])
log2 y = log2 (4x - 8)
y = 4x - 8
8 = 4x - y
4x - y = 8, second equation
Multiply the second equation by 3
12x - 3y = 24, third equation
Subtract the first equation from the third, cancelling the positive and negative 3y
It results in:
2x - 12x = - 1 - 24
-10x = -25
x = 2.5
Substituting x = 2.5 in equation (1)
2(2.5) - 3y = -1
5 - 3y = -1
-3y = -6
y = 2

Answer:
x = 9
y = 3
z = 3
Step-by-step explanation:
Triangle 1 (From the left):
5x + 7x = 13x - 9 (Sum of two interior angles of a triangle is equals to exterior opposite angle)
Grouping like terms we have:
12x - 13x = - 9
x = 9
Triangle 2 (From the left):
30y = 90 (angles at a right angle = 90)
y = 3
Triangle 3 (From the left):
15z + 12z + 36 = 39z
36 = 39z - 27z
z = 36/12
z = 3

the price of 1 toy car is $ 3, how much profit would a person have if he bought 4 of these cars and sold them for $ 5 in four?
♛♛♛♛♛♛♛♛♛♛♛♛♛♛♛
Answers
Answer:
Profit earn from selling all four cars = $8
Step-by-step explanation:
Given:
Purchase price of toy car = $3
Number of car purchases = 4
Selling price of each car = $5
Find:
Profit earn from selling all four cars
Computation:
Total amount of purchase = 3 x 4
Total amount of purchase = $12
Total amount of sales = 5 x 4
Total amount of sales = $20
Profit = sales cost - purchase cost
Profit earn from selling all four cars = 20 - 12
Profit earn from selling all four cars = $8
Answer:
$8

Jenna is opening a clothing store. She plans to start by selling T-shirts. If it
costs her $7 for each shirt, $2 for ink per shirt, and $0.10 a bag, what is her
unit cost per shirt?
O A. $9.10
O B. $2.10
O c. $4.55
O D. $7.00
Answers
Her unit cost per shirt is,
= $9.10
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
Jenna's unit cost per shirt is, $9.10
Here, We have;
Cost for each shirt = $7
Cost for ink per shirt = $2
Cost of a bag = $0.10
Hence, Cost of T-shirt is,
= Cost for each shirt + Cost for ink per shirt + Cost for bag
= $7 + $2 + $0.10
= $9.10
Thus, Her unit cost per shirt is,
= $9.10

Ellie is running down the street at 10 m/s. She sees a double-tall latte on the road ahead of her and starts sprinting. After 5 seconds have passed, Ellie is running 15 m/s. Assuming she does not change directions, what was Ellie’s acceleration?
Answers
Answer:
2m/s²
Step-by-step explanation:
acceleration = change in velocity/time taken
a = v-u/t
Given
v = 15m/s
u = 5m/s
time t = 5secs
Substitute
a = 15 - 5/5
a = 10/5
a = 2m/s²
Hence Ellie’s acceleration is 2m/s²

Answer:
y = 8x+6
Step-by-step explanation:
First find the slope since it is a linear function
m = (y2-y1)/(x2-x1)
= (18-2)/(1 1/2 - -1/2)
=16 / (1 1/2 +1/2)
= 16/2
= 8
The linear function is in the form
y = mx+b where m is the slope
y = 8x+b
Substitute the other point into the equation to determine b
10 = 8(1/2) +b
10 = 4+b
10-4 = b
6 = b
y = 8x+6

solve the inequality 14≥3x+2
Answers
Answer:
4 ≥ x
Step-by-step explanation:
14 ≥ 3x + 2
14 - 2 ≥ 3x
12 ≥ 3x
4 ≥ x
Solving the inequality 14 ≥ 3x+2 we get x ≥ 4.
What is inequality?In mathematics, an assertion of an order connection greater than, greater than, or equal to, less than, or less than or equal to between two numbers or algebraic expressions.
Given:
14 ≥ 3x+2
Switch sides
3x+2 ≥ 14
Subtract 2 from both sides of the equation, we get
3x + 2 - 2 ≥ 14 - 2
Simplifying the above equation
3x ≥ 12
Divide both sides by 3, we get
3x/3 ≥ 12/3
x ≥ 4
Therefore, the value of x ≥ 4.
