The value of cos(π/2) is 0 sinπ/2 is 1 further sinx = √3/2 thus x = π/3,2π/3.

The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.

The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.

As per the given trigonometric equation,

cos(x)cosπ/2 + sin(x)sinπ/2 = √3/2

Since, cosπ/2 = 0 and sinπ/2 = 1

cos(x)(0)+ sin(x)(1) = √3/2

sinx = √3/2

sinx = sin π/3 = sin 2π/3.

Hence "The value of cos(π/2) is 0 sinπ/2 is 1 further sinx = √3/2 thus x = π/3,2π/3".

Answer:

Growth rate = 8% = 0.08

Initial value (Po) = $255

F(t) = Po* e^rt

F(t) = $412.09897

Step-by-step explanation:

Given that:

Initial cost = $255

Rate of increase per year (r) = 8% = 0.08

Growth rate :

Final amount = Initial amount * (1 + rate)^time

Growth rate = 8% = 0.08

Initial value (Po) = $255

Exponential model for the cost :

F(t) = Initial value * e^(rate * time)

F(t) = Po* e^rt

Value after 6 years :

F(t) = Po* e^rt

t = 6

F(t) = 255 * e^(0.08*6)

F(t) = 255 * 1.6160744

F(t) = $412.09897

What are mathematics operations?

A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.

• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.

Calculating time of Betsy total work for getting paid :

Betsy Working from 6:00 AM to 12:00 PM =  6 hour

Betsy takes an unpaid lunch break from 12:00 PM to 1:00pm = 1 hour

Betsy Working from  1:00 PM to 3:30 PM =  2.5 hour

Now adding-up all the time = 6 + 1 +  2.5 hour = 9.5 hours or 9 hours 30 minutes.

Therefore,  Betsy works for about 9 hours 30 minutes daily.

Answer:

  7.  y = f(x +2) -7

  8.  y = -f(x -5)

  9.  y = f(-x) +3

Step-by-step explanation:

The general transformation can be written ...

  y = a·f(b·(x -c)) +d

'a' is the vertical expansion factor. A negative value means the graph is reflected over the x-axis.

'b' is the horizontal compression factor. A negative value means the graph is reflected over the y-axis.

'c' is the number of units of right-shift.

'd' is the number of units of up-shift.

__

7. 2 left and 7 down means (c, d) = (-2, -7), so the transformed function is ...

  y = f(x +2) -7

__

8. reflected over x and 5 right means (a, c) = (-1, 5), so the transformed function is ...

  y = -f(x -5)

__

9. reflected over y and up 3 means (b, d) = (-1, 3), so the transformed function is ...

  y = f(-x) +3

_____

The graph shows an asymmetrical function that makes it possible to tell what the transformations are. The original is dashed orange. The various y-values correspond to the problem numbers. You can see that the transformations match the problem statements.

answer on 12 square units

Answer:

B

Step-by-step explanation:

Answer:

The table will be:

x            y = 2x²         y = 2ˣ

0            0                   1

1             2                  2

2             8                  4

Step-by-step explanation:

Given the non-linear  equations

y = 2x²

y = 2ˣ

y = 2x²                              

y = 2(0)² =0

y = 2ˣ

y = 2⁰ = 1

y = 2x²                              

y = 2(1)² = 2

y = 2ˣ

y = 2¹ = 2

y = 2x²                              

y = 2(2)² = 8

y = 2ˣ

y = 2² = 4

Thus, the table will be:

x            y = 2x²         y = 2ˣ

0            0                   1

1             2                  2

Answer:

She used 2 17/20 strings of grey beads

Step-by-step explanation:

Here, we want to know the number of grey beads used

To calculate this, we simply add up the black beads number with the number of grey beads

Mathematically, that will be;

1 1/20 + 1 4/5

= 21/20 + 9/5

= (21 + 36)/20

= 57/20 = 2 17/20
