The equation of line that passes a point (–3, 7) and has slope of 4, in the point-slope form is y - 7 = 4 (x + 3)

A linear equation can be expressed in three forms:

- slope intercept form : y = mx + c

- point-slope form: y - y₁ = m (x - x₁)

- standard form: Ax + By + C = 0

Where:

m = slope

(x₁, y₁) = point on the line

A, B, C are constant

In this problem, the point is (–3, 7) and the slope is 4. Hence,

x₁ = –3

y₁ = 7

m = 4

Plug these parameters into the equation:

y - y₁ = m (x - x₁)

y - 7 = 4 (x - (-3))

y - 7 = 4 (x + 3)

Answer: 7 tens and 6 ones

Step-by-step explanation: 76 is two numbers, with a 7 in the tens place and a 6 in the ones place.

76 can be represented as 7 tens and 6 ones or as 6 tens and 16 ones. This involves understanding the place value of digits in a number and knowing that a ten can be broken down into ones.

The number 76 can be broken down into tens and ones in multiple ways. First, let's understand what tens and ones mean in the context of a number. In the number 76, '7' is the tens place, and '6' is the ones place, meaning there are 7 tens (70) and 6 ones (6) making up 76.

One way to show 76 with tens and ones is to say that there are 7 tens and 6 ones. This is a very direct method where we just count the number of tens and ones in the number.

Another way we could break down 76 is to say there are 6 tens and 16 ones. This method involves taking one of the tens and breaking it down into 10 ones, giving us a total of 6 tens and 16 ones.

If f(x) = 2x + 3 then Δy/Δx = 2 and g(x) = 2² +3 then Δy/Δx = 2.33.

The correct answer is option A.

f(x) has a rate of change of 2

g(x) has a rate of change of 2.33

So g(x) is growing faster

Let f(x) = 2x + 3 and g(x) = 2² +3

Let, ∆y /∆x denotes the ratio of y change and x change when x change exists relatively large.

If f(x) = 2x + 3

Δy/Δx = [f(3) - f(0)]/3 - 0

f(3) \(= 2*3+3 = 9\)

f(0) \(= 2*0+3 = 3\)

[f(3) - f(0)]/3 - 0 = (9 - 3)/3

= 6/3 = 2

g(x) = 2² +3

Δy/Δx = [g(3) - g(0)]/3 - 0

\($= (2^3 +3)-(2^0 +3)/3\)

\((2^3 +3)-(2^0 +3) = 7\)

\((2^3 +3)-(2^0 +3)/3\) = 7/3 = 2.33

Therefore, the correct answer is option A.

f(x) has a rate of change of 2

g(x) has a rate of change of 2.33

So g(x) is growing faster

The total VA( volt-ampere ) that must be used in a service calculation for 50' show window is 125000VA.

A volt-ampere (SI symbol: VA or V A, abbreviated as VA) is the unit of perceived power in an electrical circuit. The apparent power is equal to the product of the root mean square voltage (in volts) and the root mean square current (in amperes). Volt-amperes are commonly used to analyze alternating current (AC) circuits. In direct current (DC) circuits, this product equals the real power in watts. The volt-ampere is dimensionally identical to the watt: 1 VA = 1 W in SI units).

The distance from Amy's house to the soccer field is approximately 7.2 blocks.

To determine the distance between Amy's house and the soccer field, we can apply the Pythagorean theorem.

In this theorem, the length of the hypotenuse (the longest side of a right triangle) is the square root of the sum of the squares of the other two sides.

In this problem, the blocks walked north and east form two sides of a right triangle.

To determine the distance from Amy's house to the soccer field, we need to find the hypotenuse.

Here is the solution: To get to the soccer field, Amy walks 6 blocks north and then 4 blocks east.

This forms a right triangle with legs measuring 6 blocks and 4 blocks.

Using the Pythagorean theorem, the hypotenuse can be found by taking the square root of the sum of the squares of the legs: d=√(6²+4²)d

The researcher who has 80 participants for a study that involves four experimental conditions and who assigns participants to conditions using matched random assignment will form 20 matched clusters or blocks before assigning participants to conditions.

Matched Random Assignment is the process of grouping participants based on their similarities (matching variables) before randomly assigning them to different treatment groups (experimental conditions) to ensure that the groups are similar in all aspects except for the independent variable. This helps to control for extraneous variables that might affect the outcome of the study.

The number of matched clusters or blocks formed in matched random assignment is equal to the number of treatment groups (experimental conditions).

Since the researcher has four experimental conditions, she will form four matched clusters or blocks before assigning participants to conditions.

Therefore, the number of matched clusters or blocks that she will form before assigning participants to conditions is:

4 experimental conditions x 5 matched participants per block= 20 matched clusters or blocks.

The Quadratic equation that relates the area of both Rectangular components is 2w^2-4w=0, value of w=2, area of combined figures=20 unit^2.

What are quadratic equations ?

A quadratic equation is a second-degree algebraic equation in x. In its usual form, the quadratic equation is ax^2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term. The first requirement for an equation to be a quadratic equation is that the coefficient of x^2 is not zero (a ≠ 0). When expressing a quadratic equation in standard form, the x^2 term comes first, then the x term, and lastly the constant term. The numeric values a, b, and c are commonly expressed as integral values rather than fractions or decimals.

Now,

As Two components have same area

w*(7-w)=w*(3+w)    (Area of rectangle = length*breadth)

2w^2-4w=0     -----  1

From 1

w(2w-4)=0

w=0/2 as w can not be zero.

So, w=2

Now area of combined figure = w*(7-w)+w*(3+w)

                                                 =2*5+2*5

        area of combined figure =20 unit^2

The correct answer is option  A: The random variable is discrete. A decibel is a unit of measure used to quantify the loudness or intensity of sound.

From 0 dB (the quietest level of sound) to 140 dB (the loudest level of sound), it is measured on a logarithmic scale (the highest level of sound).

The decibel level of a siren is normally between 110 and 120 dB, which is regarded to be within or close to the threshold of human hearing.

The decibel level of a siren is measured on a logarithmic scale, making it a discrete variable. This indicates that it is measured in whole numbers rather than fractions of a decibel.

For instance, a siren's decibel level can be 110 dB, 111 dB, 112 dB, etc., but it cannot be 110.5 dB or 111.5 dB. Therefore, the decibel level of a siren is a discrete variable.

2              6

3              12

4              24

5              48

as

and

so it is indeed an exponential function

As we know that the exponential function is of the form

\(f\:\left(x\right)\:=\:ab^x\)

As we know that the y-intercept of \(f\:\left(x\right)\:=\:ab^x\) is (0, a).

so

\(\frac{3}{a}=2\)        ∵ common ratio = successor y-value ÷ previos y-value

\(a=\frac{3}{2}\)

so the value of a will be: 3/2

The probability that suits of cards are spades, hearts, and spades is 39/850 or 0.046.

According to the give question.

Three cards are drawn from a standard deck of cards without replacement.

Since,

The total number of cards in a standard deck = 52

Total number of spade cards = 13

Total number of heart cards = 13

Now,

The probabbility of getting first card as a spade card = 13/52 = 1/4

The probability of getting second card as heart card

= 13/(52 -1)     (cards are drawn without replacement)

= 13/51

The probability of getting third card as a spade card

= (13 - 1)/52 -2

= 12/50

= 6/25

Therefore, the probability that suits of the cards are spades, hearts, spades

= 1/4 × 13/51 × 6/25

= 39/850

= 0.046

the area of the region R is (5)^(4/3)/4 - 5(5)^(1/3) square units.

To find the area of the region enclosed by the function f(x) = x^3, the horizontal line y = 5, and the y-axis, we need to integrate the function f(x) over the given interval and subtract the area under the horizontal line.

First, we need to find the x-coordinate of the point where the function intersects the horizontal line y = 5. Setting f(x) equal to 5, we have:

x^3 = 5

Taking the cube root of both sides, we get:

x = (5)^(1/3)

So the region R is bounded by the y-axis, the line x = (5)^(1/3), and the horizontal line y = 5.

The area of R can be found using the integral:

A = ∫[0, (5)^(1/3)] f(x) dx - ∫[0, (5)^(1/3)] 5 dx

where the first integral calculates the area under the curve and the second integral calculates the area under the horizontal line.

Substituting the function f(x) = x^3, we get:

A = ∫[0, (5)^(1/3)] x^3 dx - ∫[0, (5)^(1/3)] 5 dx

Evaluating the integrals, we get:

A = [1/4 x^4] from 0 to (5)^(1/3) - [5x] from 0 to (5)^(1/3)

A = (1/4) [(5)^(4/3)] - 5 [(5)^(1/3)] + 0

Simplifying, we get:

A = (5)^(4/3)/4 - 5(5)^(1/3)

Using expression (L/3) / (36t) = L / (108t),  the fraction of the total singing time that all three are singing at the same time is L / (108t).

What exactly are expressions?

In mathematics, an expression is a combination of numbers, variables, and operations that represents a value or a quantity. Expressions can be composed of one or more terms, which are separated by addition or subtraction symbols.

For example, the expression 2x + 3y - 5 represents a value that depends on the values of the variables x and y. The term 2x represents a quantity that is twice the value of x, the term 3y represents a quantity that is three times the value of y, and the term -5 represents a constant value of negative five.

Now,

Let's call the length of the song "L" and the time it takes to sing one line "t". Then, we know that:

Rachel starts singing at t = 0, and she sings for a total of 4L.

Jenny starts singing at t = t, and she sings for a total of 4L.

Angela starts singing at t = 2t, and she sings for a total of 4L.

Since each line of the song is the same length, we can divide the total singing time for each person into three equal parts, one for each line. So, each person sings for a total of 12t.

Now, let's think about when all three people are singing at the same time. This happens during the second line of the first repetition of the song. Rachel is singing the first line, Jenny is singing the second line, and Angela is starting to sing the third line. The total length of time that all three people are singing together is just the length of one line, which is L/3.

Since each person sings for a total of 12t, the total singing time for all three people is 36t. Therefore, the fraction of the total singing time that all three are singing at the same time is:

(L/3) / (36t) = L / (108t)

So, the fraction of the total singing time that all three are singing at the same time is L / (108t).
