The transformations are needed to change the parent cosine function to the cosine function is

Vertical stretch of 2 and horizontal compression to a period π/2 and phase shift to π unit left and vertical shift of 1 unit down.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

If you stretch cosine function by a factor of 2, maximum will be y = 2 and minimum will be y = -2.

and, after that you shift it 1 unit down maximum will be y = 1 and minimum will be y = -3

So, vertical stretch of 2 and horizontal compression to a period π/2.

Now, the phase shift to π unit left and vertical shift of 1 unit down.

Answer:

Step-by-step explanation:

[tex]A=\frac{40^o}{360^o}\cdot \pi\cdot 10^2=\frac19\cdot100\pi=\frac{100}9\pi\, cm^2[/tex]

Given:

[tex]P(A)=0.4, P(B)=0.7, P(A\text{ and }B)=0.3[/tex]

To find:

The value of [tex]P(A\text{ or }B)[/tex].

Solution:

We know that,

[tex]P(A\text{ and }B)=P(A\cap B)[/tex]

[tex]P(A\text{ or }B)=P(A\cup B)[/tex]

It means, we have [tex]P(A)=0.4, P(B)=0.7, P(A\cap B)=0.3[/tex] and we need to find the value of  [tex]P(A\cup B)[/tex].

[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]

[tex]P(A\cup B)=0.4+0.7-0.3[/tex]

[tex]P(A\cup B)=1.1-0.3[/tex]

[tex]P(A\cup B)=0.8[/tex]

Therefore, the value of [tex]P(A\text{ or }B)[/tex] is 0.8.

Answer:

m<CAO = 56

Step-by-step explanation:

When two parallel lines are intersected by a transversal, the same-side interior angles are supplementary, meaning that their angle measures add up to (180) degrees. Using this information, substitute in the given values and solve for the unknown,

(m<DOA) + (m<CAO) = 180

Substitute,

3x + 40 + 2x = 180

Simplify,

5x + 40 = 180

Inverse operations,

5x + 40 = 180

     -40    -40

5x = 140

/5     /5

x = 28

Now substitute the value of (x) back into the given expression for the value of (<CAO). Solve to find the numerical value.

<CAO = (2x)

= 2(28)

= 56

Answer:

1. 18

2. 181

3. 101

Step-by-step explanation:

They want you to take each equation, and replace the letter with the number they give you after the equation.

3m + 2n + 4; m = 2, n = 4

This becomes

3(2) + 2(4) + 4

We multiply before we add, according to the order of operations. So next, the equation becomes:

6 + 8 + 4

= 18

———-

D^2 + 9k ; D = 10, k = 9

Numbers squared are numbers multiplied by themselves.

(10)(10) + 9(9)

= 100 + 81 = 181

Remember, multiplication always comes before addition.

Answer:

30.17feet high

Step-by-step explanation:

Given the following

the distance from the base of the pole to the tip of the shadow = 49feet (hypotenuse)

angle of elevation = 38°

Required

Height of the flagpole (opposite)

Using the SOH CAH TOA identity

Sin theta = opposite/hypotenuse

Sin 38 = H/49

H = 49sin38

H = 49(0.6157)

H = 30.17feet

Hence the flagpole is 30.17feet high

The measure of the unknown angle is 70 degrees

In circle geometry, there is a theorem that states that the angle at the centre of a circle is twice the angle at the circumference

Given the following parameters;

Angle at the circumference = x

Angle at the centre = 140 degrees

Using the given theorem;

140 = 2x

Swap

2x = 140

x = 140/2

x = 70

Hence the measure of the unknown angle is 70 degrees
