Solve the trigonometric equation for all values: -7 < or equal to x < 7 Question: Cot 1/2x-1=0

Answers

Answer 1

Answer:

x =90

Step-by-step explanation:

Cot 1/2x-1=0

Add 1 to both sides

Cot 1/2x = 0+1

Cot 1/2x = 1

1/tan1/2x = 1

Tan 1/2x = 1

1/2x = arctan1

1/2x =45

x = 45×2

x = 90

Hence the value of x is 90

find the area of the minor sector
1 r=9cm,tita=70​

Answers

Answer:

The area is 49.5 cm^2

Step-by-step explanation:

To find the area of the sector, we are going to use the formula for the area of a sector

Mathematically, we have this as;

A = theta/360 * pi * r^2

r = 9 cm and theta = 70

Substituting these values

A = 70/360 * 3.142 * 9^2

A = 49.5 cm^2

Step-by-step explanation:

a. -6 ≤ 3x < 15

steps in order to solve:

-6 ≤ 3x

= -6/3 ≤ 3x/3

= -2 ≤ x

3x < 15

= 3x/3 < 15/3

= x < 5

=> -2 ≤ x < 5

b. -3 < 2x - 1 < 7

steps in order to solve:

-3 < 2x - 1

= 1 - 3 < 2x - 1 + 1

= -2 < 2x

= -2/2 < 2x / 2

= -1 < x

2x - 1 < 7

= 2x - 1 + 1 < 7 + 1

= 2x < 8

= 2x/2 < 8/2

= x < 4

=> -1 < x < 4

c. 7 < -3n + 1 ≤ 13

steps in order to solve:

7 < -3n + 1

= -1 +7 < -3n + 1 - 1

= 6 < -3n

= 6/-3 < -3n/-3

= -2 > n

-3n + 1 ≤ 13

= -3n + 1 - 1 ≤ 13 -1

= -3n < 12

= -3n/-3 < 12/-3

= n > -4

=> -4 < n < -2

Find the equation of the line that passes through the points (1, 6) and (2, 8).
By substitution in this equation, show that (3, 10) also lies on this line.

Answers

Answer:

y = 2x + 4

Step-by-step explanation:

y2 - y1/ x2- x1  

= 8 - 6 / 2 - 1

= 2

So now our equation is y = 2x + b (from y = mx+b). Now plug in the coordinates to find the y-intercept.

y = 2x + b

8 = 2(2) + b

8 = 4 + b

4 = b

The y-intercept is 4.

If we put one of the values like the x in the equation, we should get the y value.

y = 2x + 4

y = 2 (3) + 4

y = 6 + 4

y = 10

F is directly proportional to a.
If F = 28 when a = 7 find,
F when a = 10

Answers

Answer:

Step-by-step explanation:

a=10

Step-by-step explanation:

The question can be interpreted as

F∝a

If we introduce proportionality constant k, we have

F= k.a

28= k. 7

k= 28/7

k= 4

Then the equation can be written as

F= 4.a

To find, a when F = 40?

F= 4.a

40=4 × a

a= 40/4

a= 10

Answer:

F = 40

Step-by-step explanation:

Given F is directly proportional to a then the equation relating them is

F = ka ← k is the constant of proportion

To find k use the condition F = 28 when a = 7 , then

28 = 7k ( divide both sides by 7 )

4 = k

F = 4a ← equation of proportion

When a = 10, then

F = 4 × 10 = 40
