Answer:
It means: In the first quadrant (I), all ratios are positive. In the second quadrant (II), sine (and cosec) are positive. In the third quadrant (III), tan (and cotan) are positive. In the fourth quadrant (IV), cos (and sec) are positive.
Step-by-step explanation:
Sine is positive in first and second quadrant.
We have to given that;
To find the quadrants in which sine positive.
Since, We know that;
In first quadrant (I), all ratios are positive.
In the second quadrant (II), sine (and cosec) are positive.
In the third quadrant (III), tan (and cotan) are positive.
In the fourth quadrant (IV), cos (and sec) are positive.
Hence, By above definition we get;
⇒ In first and second quadrant sine is positive
Thus, Sine is positive in first and second quadrant.

Answers
Answer:
4x-3
Step-by-step explanation:
From the length of two tangents 2x + 16 and 4x - 2. The value of x is 9.
The length of one tangent is 2x + 16.
The length of the other tangent is 4x - 2.
Theorem on the length of a tangentThe length of two tangents drawn from an external point to a circle is equal. Let's suppose AP and AQ are two tangents from point A to a circle then AP = AQ.
Consider the length of one tangent to be AP and the other tangent to be AQ from a points A to a circle.
So, from the above theorem, we get
AP = AQ
[tex]\rm 4x-2=2x+16\\\rm 4x-2x=16+2\\\rm 2x=18\\\rm x=9[/tex]
Therefore, from the length of two tangents 2x + 16 and 4x - 2. The value of x is 9.

The population of a town is increasing by 4.7% each year. If the town has 21,802 people now, how many people will it have in 7 years?
Answers
Answer:
Step-by-step explanation:
21,802 × 1.047⁷ ≈ 30,069
Answer:
1, 104, 539, 727 people.
Step-by-step explanation:
This will be an exponential function.
The equation for such is [tex]f(x) = a(b)^{x}[/tex].
a = initial value, in this case, 21,802.
b = multiplier, in this case, 4.7.
x = time, in this case, 7.
1. Insert your variables:
[tex]f(x) = 21,802(4.70)^{7}[/tex]
2. Solve parenthesis.
[tex]4.7^{7} = 50,662.312[/tex]
[tex]f(x) = 21,802(50,662.312)[/tex]
3. Solve.
[tex](21,802)(50,662.312) = 1,104,539,727.23[/tex]
You would round you answer off, since you can't have 23% of a person, and your answer would be 1, 104, 539, 727 people.

The value of the equation after simplifying is A = √6
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first number be p = √30
Let the second number be q = √5
And , A = p/q
Substituting the values in the equation , we get
A = √30 / √5
On further simplification , we get
A = √ ( 30/5 )
A = √6
Therefore , the value of A is √6
Hence , the equation is A = √6

Answers
Explanation:
Mary worked from Monday to Saturday last week and bought lunch in the company’s restaurant
every day.
Her lunches cost a different amount every day.
Each lunch cost a multiple of 20¢.
The most expensive lunch of the week cost $7.60 and the cheapest one cost $4.40.
Friday’s lunch cost exactly 11⁄2 times as much as Wednesday’s lunch.
Tuesday’s lunch cost $1.20 more than Thursday’s lunch.
(a) What is the minimum total that Mary’s six lunches last week could have cost?
(b) What is the maximum total that Mary’s six lunches last week could have cost?
Answers
Answer:
25%. 4.80 divided by 1.20 = 4 x 100 = 40o%
Using logical and arithmetic principles, the minimum and maximum total Mary could spend is $31.20 and $40.40 respectively.
Cheapest lunch fee = $4.40 = 440¢Most expensive = $7.60 = 760¢Minimum total cost of lunch :
Lunch cost will increase steadily by multiple of 20¢ from the cheapest unless given a stated constraint
Monday = $4.80
Tuesday = $4.40 + 1.20 + 0.2 = $5.80
Wednesday = $4.40
Thursday = $5.80 - $1.20 = $4.60
Friday = 3/2($4.40) = $6.60
Saturday = $5.00
Total = $(4.40 + 5.80 + 4.80 + 4.60 + 6.60 + 5.00) = $31.20
Maximum Total :
Lunch cost will decrease steadily by multiple of 20¢ from the most expensive unless given a stated constraint
Monday = $7.40
Tuesday = $7.60 + 1.20 = $6.40
Wednesday = $4.80
Thursday = $7.60
Friday = 3/2($4.80) = $7.20
Saturday = $7.00
Total = $(7.40 + 6.40 + 4.80 + 7.60 + 7.20 + 7.00) = $40.40
Therefore, the minimum and maximum total Mary could spend is $31.20 and $40.40 respectively.
