Answer:

A. cos(60°)

Step-by-step explanation:

sin(30 degrees) = 0.5

cos(60°) = 0.5

cos(90°) = 0

sin(60°) = √[tex]\frac{3}{2}[/tex]

cos(30°) = √[tex]\frac{3}{2}[/tex]

so it's A.

Ace

The sin 30° is equivalent to the expression cos 60°. Then the correct option is A.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

The equivalent is the expression that is in different forms but is equal to the same value.

The expression is given below.

⇒ sin(30°)

We know that the formula which is written as,

sin (90° - x) = cos x

Then by the above property, the expression is written as,

sin 30° = sin (90° - 30°) = cos x

sin 30° = cos 60°

The sin 30° is equivalent to the expression cos 60°. Then the correct option is A.

Answer:9,540

Step-by-step explanation:

Answer:

4%

Step-by-step explanation:

First, we turn this into a fraction:

3/75 = 1/25 = 4%

So 3 is 4% of 75

Using the percentage expression 4 percent of the number 75 is 3.

We have,

Given percentage = M

Under the condition, an expression can be written as,

M% of 75 = 3

Solve for M.

M/100 x 75 = 3

Multiply 100 on both sides.

75M = 3 x 100

75M = 300

Divide 75 on both sides.

M = 300/75

M = 4

Cross checked.

4% of 755

4/100 x 75

4/4 x 3

1 x 3

3

True.

Thus,

4 percent of number 75 is 3.

Answer:

5 (3 c + 4)

Step-by-step explanation:

We factor out the 5, to get 5(3c+4)

We check by distributing the 5, and we get 15c+20 which is correct!

Hope this helps

The expression equivalent to 15c + 20 is 5(3c + 4).

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given expression is 15c + 20.

We have to find an equivalent expression of this using the distributive property.

For three numbers or expressions a, b and c, Distributive property states that,

a (b + c) = ab + ac

In the expression of 15c + 20, write each terms as a multiple of a common factor.

15c = 5 × 3c

20 = 5 × 4

15c + 20 = (5 × 3c) + (5 × 4)

              = 5 (3c + 4)

Hence the correct expression which is equivalent to the given expression is 5 (3c + 4).

Answer:

[tex]W_s \approx5.3[/tex]

Step-by-step explanation:

From the question we are told that

Height [tex]H=3.5ft[/tex]

Weight [tex]W= 6ft[/tex]

Depth  [tex]D=0.95ft[/tex]

Generally the equation for ellipses is given as

[tex]\frac{x^2}{a^2} +\frac{y^2}{b^2} =1[/tex]

Where

[tex]b=H/2\\b=3.5/2\\Therefore\\b=1.75\\a=W/2\\a=6/2\\Therefore\\a=3\\[/tex]

[tex]\frac{x^2}{3^2} +\frac{y^2}{1.75^2} =1[/tex]

Generally to find y in the equation [tex]\frac{x^2}{a^2} +\frac{y^2}{b^2} =1[/tex]

[tex]y=-b+d[/tex]

[tex]y=-1.75+0.95[/tex]

[tex]y=-0.8[/tex]

Therefore

[tex]\frac{x^2}{3^2} +\frac{(0.8)^2}{1.75^2} =1[/tex]

[tex]\frac{x^2}{3^2} =1-\frac{(0.8)^2}{1.75^2}[/tex]

[tex]\frac{x^2}{3^2} =1-0.2089795918[/tex]

[tex]X^2 =3^2(1-0.2089795918)[/tex]

[tex]X^2 =7.119183674[/tex]

[tex]X =\sqrt{7.119183674}[/tex]

[tex]X =2.66817984[/tex]

Therefore the width of the given stream is

[tex]W_s=2.66817984*2[/tex]

[tex]W_s=5.33635968[/tex]

[tex]W_s \approx5.3[/tex]

Gallons of punch used = 4.94 gallons

Step-by-step explanation:

Given that:

Liters of punch purchased = 25 liters

Liters of punch left over = 6 liters

Liters of punch used = 25 - 6 = 19 liters

According to the given statement;

1 liter = 0.26 gallons

19 liters = 0.26*19 gallons

19 liters = 4.94 gallons

Hence,

Gallons of punch used = 4.94 gallons

Answer:

The model is [tex]V(t)=2239+249\sin(\frac{\pi}{2}t)[/tex].

Step-by-step explanation:

Consider the given information.

The volume of air inside the lungs increases or decreases so for this we will use the basic sine function [tex]B(t)=d+a\sin[b(t+ \frac{c}{a})][/tex] as our parent function.

Let us assume that the phase shift is 0 it means [tex]\frac{c}{b}=0[/tex].

The air that moves into and out of the lungs is about 498 mL.

It means the amplitude of the function will vary by 249(half of 498).

The reserve and residual volumes of air that remains in the lungs occupy about 1990 mL which is the minimum air in the lungs.

So, the max air will be: 1990+498 =2488 mL

And the average will be d=1990+249=2239 ml

The horizontal stretch will be  [tex]b=\frac{2\pi}{4}=\frac{\pi}{2}[/tex] as we know that period of [tex]y=\sin t[/tex] is [tex]2\pi[/tex] and respiratory cycle for an average human takes about 4 seconds.

Hence, the model is [tex]V(t)=2239+249\sin(\frac{\pi}{2}t)[/tex].
