Answer:

Step-by-step explanation:

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

to factorise first, find the highest common factor of each of the terms in the expression then, write the highest common factor (HCF) in front of any brackets atlast, fill in each term in the brackets by multiplying out.

The value of the expression after factorization will be;

⇒ 2ab (b + 4a)

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 2ab² + 8a²b

Now,

Factorize the expression as;

⇒ 2ab² + 8a²b

⇒ 2ab × b + 2×2×2a×a×b

⇒ 2ab (b + 4a)

Thus, The value of the expression after factorization will be;

⇒ 2ab (b + 4a)

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.

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.

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

Remark

If the entire circle was shaded the radius sweeping out the circle would go through 360 degrees.

So the way to solve this problem is to multiply the entire area of the circle by (81/360)

Area of the sector = (81/360) * pi * r^2

pi = 3.14

r =8.91 cm

Area of the sector = (81/360) * 3.14 * 8.91^2

Area of the sector = 56.09

Rounded to the nearest tenth, the answer is 56.1

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)

=  ∛(8/125) = 2/5

Ratio of their surface area = 2²/5²

Ratio of their surface area = 4/25.

3. Ratio of the volume of the smaller cyinder to that of the larger = 8³/24³

The actual price is 13.6% lower than the expected price.

CPI or Consumer Price Index is a measure of determining retail inflation in an economy, based on price variations in a fixed basket of goods and services, over overtime periods.

Let's suppose the expected price is x.

The percent relation of the actual price of a winter hat to the expected price is given by;

CPI = ( expected price ) : ( price in 1983 ) × 100

219  =  ( x  : 12.95 ) × 100

Divide both sides by 100.

x : 12.95 = 2.19

x =2.19 × 12.95

x = $28.36 ( expected price )

p = ( 24.50 × 100 ) / 28.36

p= 2450/28.36

p = 86.4 %

100 % - 86.4 % = 13.6 %

Hence, the actual price is 13.6% lower than the expected price.
