Answer:

Step-by-step explanation:

Trigonometric identities are used to show the equality of expressions involving trigonometric functions. These trigonometric functions are the sine, the cosine, and the tangent as well as their respective reciprocals which are cosecant, the secant, and the cotangent,

Some trigonometric identities are:

tanθ = sinθ / cosθ; secθ = 1 / cosθ; cosecθ = 1 / sinθ; cotθ = 1 / tanθ = cosθ / sinθ

The angle addition formula for cos is given as:

cos(α + β) = cosαcosβ - sinαsinβ

Therefore:

cos(a + b) = cosacosb - sinasinb

Answer:

w = 13

Step-by-step explanation:

Right angle: 90°

Write an equation:

(4w + 5)° + 33° = 90°

Solve for w.

(4w + 5)° = 90° - 33°

(4w + 5)° = 57°

You can take away the brackets.

4w + 5 = 57

Isolate w.

4w = 57 - 5

4w = 52

w = 52 ÷ 4

w = 13

Answer:

The answer to the first one is y=3/2x-27/2

The answer to the second one is y=-3/5x+6/5

Step-by-step explanation:

1. 2y-3x=-27

first, you want to add '3x' to both sides.

2y=3x-27

then you want to divide '2' from both sides. you do not want to use the 'y' because you want to keep the 'y' on its own side.

y=3/2x-27/2

2. 5y+3x=6

First, you want to subtract '3x' from both sides.

5y=-3x+6

Now, you want to divide '5' from both sides.

y=-3/5x+6/5

Step-by-step explanation:

Answer:

a) The maximum height that the ball reaches is 4 meters.

b) The height of the ball when it is released from thrower's hand is 2 meters.

c) The ball will take approximately 0.966 seconds to hit the surface of Jupiter.

Step-by-step explanation:

a) Let [tex]h(t) = -12.5\cdot (t-0.4)^{2}+4[/tex], where [tex]t[/tex] and [tex]h(t)[/tex] are the time and height, measured in seconds and meters. Since this equation is in vertex form, the maximum height corresponds to the value associated with the dependent variable (height). That is:

[tex]h(t) -4 = -12.5\cdot (t-0.4)^{2}[/tex]

Hence, the maximum height that the ball reaches is 4 meters.

b) The height of the ball when the ball is released from thrower's hand is the height of the ball at [tex]t = 0\,s[/tex]. Then, we evaluate the function:

[tex]h(0) = -12.5\cdot (0-0.4)^{2}+4[/tex]

[tex]h(0) = 2\,m[/tex]

The height of the ball when it is released from thrower's hand is 2 meters.

c) The instants when the ball hits the ground are those instants [tex]t[/tex] so that [tex]h(t) = 0[/tex]. Then:

[tex]-12.5\cdot (t-0.4)^{2}+4 = 0[/tex]

[tex]-12.5\cdot (t^{2}-0.8\cdot t +0.16)+4 = 0[/tex]

[tex]-12.5\cdot t^{2}+10\cdot t +2 = 0[/tex]

By the Quadratic Formula we obtain the following roots:

[tex]t_{1} \approx 0.966\,s[/tex], [tex]t_{2}\approx -0.166\,s[/tex]

Only the first root is physically reasonable, since time is a positive real variable.

The ball will take approximately 0.966 seconds to hit the surface of Jupiter.

Answer:

pretty sure the tree's 20 feet

According to proportion if a tree casts a shadow of 40 feet it;s height is 20 feet.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

We know 1 yard is 3 feet.

Given, The shadow of the tree is 40 feet long. A yardstick placed next to the tree casts a 6-foot shadow and assuming the height of the tree to be x.

∴ x : 40 : : 3 : 6.

x/40 = 3/6.

6x = 120.

x = 20 feet.

Step-by-step explanation:

Case 1 :

[tex]3x + 2y = 6 \\ 4x + y = 2 \\ 3x = 6 - 2y \\ x = \frac{6 - 2y}{3} = \\ x = 2 - \frac{2y}{3} \\ 4(2 - \frac{2y}{3} ) + y = 2 \\ 8 - \frac{8y}{3} + y = 2 \\ - 1.67y = - 6 \\ [/tex]

[tex]y = 3.59 \\ x = 2 - \frac{2y}{3} \\x = 2 - \frac{2 \times 3.59}{3} \\ \\ x = - 0.39[/tex]

Case 2 :

[tex]3x + 2y = 6 \\ 4x - y = 2 \\ x = 2 - \frac{2y}{3} \\ 4(2 - \frac{2y}{3} ) - y = 2 \\ 8 - \frac{8y}{3} - y = 2 \\ - 3.67y= - 6 \\ y = 1.63[/tex]

[tex]x = 2 - \frac{2y}{3} \\ x = 2 - \frac{2 \times 1.63}{3} \\ x = 2 - 1.087 \\ x = 0.913[/tex]

Answer: This means that the population increased a 20% between the year 2000 and the year 2010.

Step-by-step explanation:

In this case, we have that 25,000 is the 100%.

Now we want to know which percentage represents 30,000

Let's suppose that the percentage is X.

Then we can have a system of equations:

30,000 = X

25,000 = 100%

To find the value of X, we can take the quotient of these two equations:

30,000/25,000 = X/100%

(30,00/25,000)*100% = X = 120%

Then in the 2000 we had a 100%, and in the 2010 there was a 120%.

The difference is:

120% - 100% = 20%

This means that the population increased a 20% between the year 2000 and the year 2010.

Answer:

40 people

Step-by-step explanation:

Step one:

given data

let the total number of persons be x

There are 28 women

The number of men = 30% of x

Step two:

So the total person is given as

30/100*x+28= x

solve for x

0.3x+28= x

collect like terms

x-0.3x= 28

0.7x= 28

divide both sides by 0.7

x= 28/0.7

x= 40 people

Step-by-step explanation:

7x + 10 = 4x + 16
