118°

The overall shape is a quadrilateral. meaning total angles on the inside = 360°

each side is equal and therefore both CDE and CFE are the same. 90 + 34 = 124

360 - 124 = 236

236/2 = 118 therefore you answer is 118°

If the correlation between variables a and b is +0.52, then it shows that as value on A increases, the value on B increases

The correlation between variable a and variable b = +0.52

The correlation is defined as the statistical variable that show the relationship between the variables. So when one variable increases another variable increase or if one variable decreases another variable decreases. So correlation show the the variable changes at constant rate.

In the given details

The correlation between variable a and variable b is +0.52. The sign of the correlation is positive so variable a is increasing and the variable b will also increases at constant rate

Therefore, the best interpretation of correlation is as value on A increases, the value on B increases

The coordinates of the point P that is 2/5 of the way from A to B are:

P = (-5.6, 11,2)

If we want to find a point that is 2/5 of the way between two points (x₁, y₁) and (x₂, y₂), then we need to use the formula:

( (3/5)x₁ + (2/5)x₂,  (3/5)y₁ + (2/5)y₂)

Here the two points are (-8, -2) and (6, 19), using the above formula we will get the point P:

P = ( (3/5)*-8 + (2/5)*-2,  (3/5)*6 + (2/5)*19)

P = (-5.6, 11,2)

Function 2: Domain: - 4 ≤ x < 4, Range: - 4 ≤ y < - 2, y = (5 / 9) · x² - 2

In this question we must the determine the domain and the range of each of two functions. The set of elements for the domain corresponds to the horizontal axis of the Cartesian plane, represented by variable x, while the vertical axis corresponds to the vertical axis of that plane, represented by variable y.

Now we proceed to determine the domain and the range of each function:

Function 1

Domain: 2 ≤ x < 3, Range: 1 < y ≤ 3

The definition of the function is:

3 = 2 · m + b

2 = 2.5 · m + b

(m, b) = (- 2, 7)

y = - 2 · x + 7

After the linear equation method the answer is 6 Zoomas and 5 Popsies.

What is an linear equation?

Equations with the highest degree of 1 are called linear equations. This means that the exponent of the variable in the linear equation is greater than 1. The graph of a linear equation is always a straight line.

There is a linear equation in one variable and a linear equation in two variables.

It is given that there are two types of alien live on the planet Starlight Zoomas and Popsies.

Zoomas have 3 eyes and 2 legs

Popsies have 4 eyes and 5 legs

There are total 38 eyes and 37 legs

Let there are x number of Zoomas and y number of Popsies.

According to question:

3x + 4y = 38 ..........(1)

2x + 5y = 37 ...............(2)

Solve the above system of equation.

Find the value of x from the equation(1)

3x + 4y = 38

3x = 38 - 4y

x = [tex]\frac{38-4y}{3}[/tex]

Substitute this value of x in equation(2)

2( [tex]\frac{38-4y}{3}[/tex]) + 5y = 37

⇒ [tex]\frac{76-8y}{3}+5y = 37[/tex]

⇒ [tex]\frac{76-8y+15y}{3}=37[/tex]

⇒ 76 + 7y = 111

⇒ 7y = 111 - 76

⇒ 7y = 35

⇒ y = 35/7 = 5

Substitute this value of y in the value of x

x = [tex]\frac{38-4y}{3}[/tex]

x = [tex]\frac{38-4(5)}{3}=\frac{38-20}{3}=\frac{18}{3}=6[/tex]

The rate of change of base is 5 cm/min.

The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity. In simple terms, in the rate of change, the amount of change in one item is divided by the corresponding amount of change in another. The rate of change formula gives the relationship describing how one quantity changes in relation to the change in another quantity.

Let us assume that

h = height of the triangle

[tex]\frac{dh}{dt}[/tex] = rate of increase of height = 1 cm/min

A = Area of triangle

[tex]\frac{dA}{dt}[/tex] = rate of increase of area = 13 cm²/min

Area of traingle, A = 1/2*(b*h)

When A = 12 cm² and h = 4 cm,

Put in above formula,

12 = 1/2 * (b)(4)

∴ b = 6 cm

A = 1/2 * b*h

[tex]\frac{dA}{dT} = \frac{1}{2}h\frac{db}{dt} + \frac{1}{2}b\frac{dh}{dt} \\\\13 = \frac{1}{2}*4* \frac{db}{dt} + \frac{1}{2}*6*1\\\frac{db}{dt} = 5 cm/min[/tex]

Answer: A. No, because two points with the same x-value have different y values.

Step-by-step explanation: A function is a relation in which each element in the domain (the set of x-values) is paired with exactly one element in the range (the set of y-values). If there are two points with the same x-value but different y-values, then there is more than one y-value for a given x-value, which violates the definition of a function. Therefore, the given relation is not a function.

Answer:

n = p+3q

Step-by-step explanation:

2^p x 8^q = 2^n

Exponent rules

Rewriting 8 as 2^3

2^p x 2^3^q = 2^n

Using the rule a^b^c = a^(b*c)

2^p x 2^3q = 2^n

Using the rule a^b * a^c = a^(b+c)

2 ^(p+3q) = 2^n

Since the bases are the same, the exponents are the same

p+3q = n

Answer:

[tex] \sf \: p + 3q = n[/tex]

Step-by-step explanation:

[tex]2^p*8^q=2^n[/tex]

First, write 8^q as a power of 2.

(a) The fraction for the given percentage is 3% = 3/100 and its decimal number is 0.03.

(b) The fraction for the given percentage is 15% = 15/100 = 3/20 and its decimal number is 0.15.

Here the fractions 15/100 and 3/20 are equivalents.

Two fractions whose numerators and denominators are different but whose value is the same are said to be equivalent fractions.

For example, a/b = k and c/d = k. Then a/b = c/d.

The fractions a/b and c/d are equivalent fractions.

Given percentages are 3% and 15%.

A percentage is a ratio of the parts in the whole of 100 parts.

So, 3% = 3/100

This is nothing but a fraction.

To convert it into decimals, divide the numerator by the denominator. So, we get 3/100 = 0.03.

Similarly, for 15%, the fraction is 15/100

This fraction when divided by 5 in both numerator and denomiantor, we get (15/5)/(100/5) = 3/20

So, the fraction 3/20 is the equivalent fraction for the fraction 15/100 Since their values are the same i.e., 0.15. Thus, the decimal number for those fractions is 0.15.
