Step-by-step explanation:

The Pythagorean identities are sin² θ + cos² θ = 1, 1 + tan² θ = sec² θ, and 1 + cot² θ = cosec² θ. Then the correct options are B, C, and E.

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function. The Pythagoras is the sum of the square of two sides is equal to the square of the longest side.

We know that

[tex]\rm H^2 = P^2+B^2[/tex]

Divide the  equation by H², then we have

[tex]\rm\dfrac{P^2}{H^2}+\dfrac{B^2}{H^2} = 1 \\\\\sin ^2 \theta + \cos ^2 \theta = 1[/tex]

Similarly, the equation is divided by P² and B², then we have

[tex]\rm 1 + \tan ^2 \theta = \sec ^2 \theta \\\\1 + \cot ^2 \theta = cosec ^2 \theta[/tex]

Answer:

14w

Step-by-step explanation:

Width = w

Length is 6 time its width. so, multiply w by 6

length = 6*w = 6w

Perimeter of rectangle = 2* (length + width)

                                        = 2*(6w + w)

                                        = 2*7w

                                         = 14w

Answer:

y-4=-2/5(x+5)

Step-by-step explanation:

Points slip form is y-y₁=m(x-x₁)

Since you have a graph we can see the line goes down 2 and over 5. Since the slope is going downwards it is a negative slope. This mean m=-2/5. Then pick any point on the line ( I chose (-5,4)) and plug it in for y₁ and x₁.

The probability that the first survey chosen indicates four children in the family, and the second survey indicates one child in the family is 1/5.

The surveys are chosen with replacement (the first one is replaced before the second is chosen), and the events are independent.  

This means that the probability of both together is the product of each event's probability.

The probability of choosing a survey that indicates 4 children in the family is 8/60 since there are 8 surveys with 4 children out of a total of (9+18+22+8+3) = 60 surveys.

The probability of choosing a survey that indicates 1 child is 9/60 since there are 9 surveys with 1 child out of a total of 60.

Together this gives us;

[tex]= \dfrac{8}{60} \times \dfrac{9}{60}\\\\ =\dfrac{ 72}{360} \\\\ =\dfrac{1}{5}[/tex]

Hence, the probability that the first survey chosen indicates four children in the family, and the second survey indicates one child in the family is 1/5.

Answer:

8 meters of ribbon

Step-by-step explanation:

because a square has four sides so if you do 2×4 =8

By taking a quotient, we will see that the number of guests is 540.

Because we know that each guest ate a fixed amount of pizza, and there was no pizza left, we know that the number of guests will be equal to the quotient between the total number of pizzas bought, and the amount of pizza that each guest ate.

This is:

[tex]N = \frac{90}{1/6}[/tex]

We can rewrite that quotient as:

[tex]N = \frac{90}{1} / \frac{1}{6} = \frac{90*6}{1*1} = 540[/tex]

So the number of guests is 540.

sine and cosecant : positive in Q1 and Q2

cosin and secant:   positive in Q1 and Q4

tangent and cotangent:  positive in Q1 and Q3.

Answer:

Quadrant I

Step-by-step explanation:

In the first quadrant all the 6 functions are positives.

Think instead of (x, y) any point has now the coordinate (cos α, sin α) so in quadrant I we have x, y positive therefore sin α and cos α are positive.

Tangent α is positive because is sinα/cosα = positive /positive = a positive

Cotangent α= 1/tan α = cosα / sinα = positive /positive = a positive

Secant α = 1/cos α = 1/ a positive number = a positive number

Cosecant α = 1/sin α = 1/ a positive number = a positive number

Step-by-step explanation:

The range of values for x is {2, 26, 2.5, 5} in the given case where we have to enter values.

To provide a range of values for x based on the given information, we need to solve the equation 2x+10 = 14, 62, 15, and 20.

Let's solve the equation for each given value: 1. 2x+10 = 14:

Subtract 10 from both sides of the equation: 2x = 4

Divide both sides of the equation by 2: x = 2 2. 2x+10 = 62:

Subtract 10 from both sides of the equation: 2x = 52

Divide both sides of the equation by 2: x = 26 3. 2x+10 = 15:

Subtract 10 from both sides of the equation: 2x = 5

Divide both sides of the equation by 2: x = 2.5 4. 2x+10 = 20:

Subtract 10 from both sides of the equation: 2x = 10

Divide both sides of the equation by 2: x = 5

Therefore, the range of values for x is {2, 26, 2.5, 5}.

Step-by-step explanation:

9x + 4y = -3 (Given)

Multiply both sides of the equation by 6, we find:

6(9x + 4y) = 6(-3)

-> 6(9x + 4y) = -18

Given

We need to evaluate 6(9x + 4y).

Substitute the value of 9x + 4y in the expression.

The circumference of the base of the silo that the farmer plans to build to store chicken feed is 28.8 ft.

A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.

The volume of a cone is expressed as;

V = (1/3)πr²h

Where r is radius of the base, h is the height of the cone and π is constant pi ( π = 3.14 )

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The circumference of a circle is expressed mathematically as;

C = 2πr

Where r is radius and π is constant pi ( π = 3.14 )

Given the data in the question;

We substitute our values into the expression above find the radius of the base of the silo.

V = (1/3)πr²h

132ft³ = (1/3) × 3.14 × r² × 6ft

132ft³ = 6.28ft × r²

r² = 132ft³ / 6.28ft

r² = 21.0191ft²

r = √21.0191ft²

r = 4.58ft

Now, since the radius of the base of the silo is 4.58ft, the circumference of the base will be;

C = 2πr

C = 2 × 3.14 × 4.58ft

C = 28.8ft

Therefore, the circumference of the base of the silo that the farmer plans to build to store chicken feed is 28.8 ft.

Answer:

Mrs. Burgess will save $48 by buying a monthly pass.

Step-by-step explanation:

Let's compare the one-day pass to the monthly pass by finding how much 20 one-day passes will cost.

Multiply the price for a one day pass, $9.65, to the gym by 20 days:

Compare this price to the monthly pass price by subtracting these values.

If Mrs. Burgess buys the monthly pass of $145 instead of buying 20 day passes for $193, she will save $48.

Given that the solids are similar, we have:

1. 5/3

2. 4/25

3. 512/13,824

If two solids have a surface area of A and B respectively, and a and b are their respective corresponding linear measures, the following ratio would be true for the similar solids:

Surface area for A/Surface area for B = a²/b².

Volume for A/Volume for B = a³/b³.

1. If the two pyramids are similar, therefore:

Ratio of the height of larger to the smaller pyramid = √(525/189) = √(25/9)

Ratio of the height of larger to the smaller pyramid = 5/3

2. Ratio of the linear measure of the smaller prism to the larger prism = ∛(24/375)

Ratio of their surface area = 2²/5²

Step-by-step explanation:

Let the length be L

Formula

SA = 2Lw + 2Lh + 2wh

Givens

h = 15 cm

w = 6 cm

L = ?

SA = 684 cm^2

Solution

Substitue what you know into the given formula

2*6*L + 2*15*L + 2 * 6 * 15 = 684         Combine

12*L + 30*L + 180 = 684                         Combine again

42L + 180 = 684                                     Subtract 180 from both sides.

42L +180 -180 = 684 - 180            

42L = 504                                               Divide by 42

Answer:

22.5 cm^2

Step-by-step explanation:

Amount of paper is going to be measured in area, so we want the surface area of the cone.  Since it is a cub it doesn't have a base, so we don't need to count it.  

Area of the cone without the base, or what is called the lateral area is pi*r*s where r is the radius and s is the slant height.  and of course radius is d/2 where d is the diameter.  so let's plug it in.  We know diameter is 6 and slant height is 7.5

SA = pi * r * s

SA = pi * d/2 * s

SA = pi * 6/2 * 7.5

SA = 22.5 cm^2

So you will need 22.5 square centimeters of paper.
