Answer:

(2sin a - 1)(2sin a + 1)

Step-by-step explanation:

Here, we want to express what is given as a product

Mathematically;

cos2a = 1-2sin^2A

So we have;

1-2(1-2sin^a)

= 1 - 2 + 4sin^2a

= 4sin^2a - 1

Using the difference of two squares, this is;

(2sin(a) - 1)(2sin a + 1)

In mathematics →

Given is that you buy a watch for $60.

Total cost of watch -

{C} = ${60 + (6% of 60)}

{C} = ${60 + (6/100 x 60)}

{C} = $(60 + 3.6}

{C} = $63.6

New sale price -

{D} = 60 - (15% of 60)

{D} = 60 - (15/100 x 60)

{D} = 60 - 9

{D} = $51

Total cost of watch including tax -

{CT} = 51 + (6% of 51)

{CT} = 51 + 3.06

{CT} = 54.06

Therefore, the answers to each part is given above.

Step-by-step explanation:

Answer:

The time can not be negative. Thus, the domain of the given graph function must have the interval [0, ∞].

In other words, t ≥ 0.

Step-by-step explanation:

We know that the domain of a function is the set of input or argument values for which the function is real and is defined.

Given that the graph is showing the height of a thrown ball x seconds after it is thrown.

We must check that the time can not be negative. Thus, the domain of the given graph function must have the interval [0, ∞].

In other words, t ≥ 0.

Step-by-step explanation:

exterior angle = 60°

exterior angle = 360/n

60° = 360°/n

60n = 360°

n = 6

Answer:

1/3 of the people come by bus

2/3 of the people come by car

Step-by-step explanation:

The probability of getting a 1 or 2  by rolling the six sided number cube is

P ( 1or 2) = 1/6 + 1/6= 2/6= 1/3

The total probability is always 1 so to get the probability of people arriving by car we subtract the probability of people arriving by bus from 1.

P ( not getting 1 or 2) = 1- P ( 1or 2)

                               = 1- 1/3= 2/3

The probability of people arriving by bus is 1/3 and the probability of people arriving by car is 2/6or 2/3.

Answer:

C (g) = 2.75g

Answer:

Step-by-step explanation:

The standard expression of equation of a  line in slope-intercept form is expressed as;

y = mx+c

m is the slope

c is the intercept

Given

slope m = -3

Point (x, y) = (-1, 3)

x = -1 and y = 3

Get the intercept

To get the intercept c, we will substitute the given values into the equation above to have;

y = mx+c

3 = -3(-1)+c

3 = 3 + c

c = 3-3

c = 0

Substitute m = -3 and c = 0 into the equation above;

y = mx+c

y = -3x+0

y = -3x

Hence the required linear equation is y = -3x

Answer:

The area of the segment AYB is 271.0413985 cm²

Step-by-step explanation:

The rule of the area of a sector is A = [tex]\frac{\alpha }{360}[/tex] × π r², where

The area of a triangle is A = [tex]\frac{1}{2}[/tex] × s1 × s2 × sinФ

∵ Area of the segment AYB = Area the sector AOB - Area ΔAOB

∵ The radius of the circle is 21 cm

∴ r = 21 cm

∵ The central angle of the sector is 120°

∴ α = 120°

∵ π = [tex]\frac{22}{7}[/tex]

→ Substitute them in the rule of the area of the sector to find it

∵ Area sector AOB = [tex]\frac{120}{360}[/tex] × [tex]\frac{22}{7}[/tex] × (21)²

∴ Area of sector AOB = 462 cm²

∵ OA and OB are the radii of the circle

∴ s1 = OA and s2 = OB

∴ s1 = s2 = 21 cm

∵ The angle included between them is 120°

∴ Ф = 120°

→ Substitute them in the rule of the area of the triangle to find it

∵ Area of the Δ = [tex]\frac{1}{2}[/tex] × 21 × 21 × sin(120)

∴ Area of the Δ = 110.25√3 cm²

∵ Area of the segment AYB = Area the sector AOB - Area ΔAOB

∴ Area of the segment AYB = 462 - 110.25√3

∴ Area of the segment AYB = 271.0413985 cm²

Answer:

Step-by-step explanation:

To simplify the expression:

4(3x+2) - 2

The first step is to open the brackets

= 4 * 3x + 4* 2 - 2

= 12x + 8 - 2

= 12x - 6

Factor out the above expression, we get;

= 6(2x - 1)

To factor out the expression:

20b - 16

the factor that can be divided by 20 and 16 without remainder is 4;

So, we have:

= 4(5b - 4)

Answer:

7.6 miles

Step-by-step explanation:

Given the coordinate points :

A(−3, 1), B(2, 3), and C(4, −1)

Distance (d) between A and B:

x1 = - 3 ; x2 = 2 ; y1 = 1 ; y2 = 3

d = √(x2 - x1)² + (y2 - y1)²

d = √(2 - (-3))² + (3 - 1)²

d = √25 + 4

d = 5.385 miles

BC :

d = √(x2 - x1)² + (y2 - y1)²

d = √(4 - 2)² + (-1 - 3)²

d = √2² + (-4²)

d = √4 + 16

d2 = 4.4721359 miles

(1/2) of d2 = 1/2 * 4.4721359 = 2.236 miles

Total distance = (5.385 + 2.236) miles

Total distance driven before getting stuck in traffic = 7.6 miles
