Answer 1

Answer:

A) 6

Step-by-step explanation:

in a 30-60-90° Δ the ratio of side lengths is 1 : [tex]\sqrt{3}[/tex] : 2

so we can set up this proportion and cross-multiply:

[tex]\sqrt{3}[/tex] / 1 = y / 2[tex]\sqrt{3}[/tex]

y = 2[tex]\sqrt{3}[/tex][tex]\sqrt{3}[/tex] which is 2x3 or 6

How do you check if an inverse is a function?

Answers

If a value of y relates only to one value of x, then the function does have an inverse function.

Define the term function and its inverse?

A relation between such a collection of inputs and outputs is known as a function.

A function is, to put it simply, a connection between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is just the input.If and only if the outcome of reflecting a function's graph about the line y = x is the function's graph, then the function f does have an inverse (passing from the vertical line test).

Thus, if a value of y relates only to one value of x, then the function does have an inverse function.

What is the graph of the linear equation 2x +3y 6 that cuts the Y-axis at the point?

Answers

The graph of the linear equation 2x + 3y = 6 is a straight line that cuts the Y-axis at the point (0,2).

A linear equation is an equation in which the highest power of the variable is 1.

The general form of a linear equation is:ax + by = c where a, b and c are constants and x and y are variables. This equation represents a straight line when plotted on a graph.

The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept

To find the points at which the line will intersect y-axis,

take x=0 and substitute in the linear equation 2x+3y=6

2(0) + 3y = 6

3y = 6

y = 2

So the point where the line cuts the Y-axis is (0,2)

The straight line of the linear equation 2x+3y=6 intersects the y-axis at (0,2).

• She needs 153 points for a free movie ticket.

Equation :

Answer v=

Answers

The number of visits Jaya can make to earn his first free movie ticket is 8

Total reward points received for signing up by Jaya = 85 rewards point

Total reward points received for each visit to the theatre by Jaya = 8.5 rewards point

Total reward points needed to Jaya for getting a free movie ticket = 153 rewards point

Let x represents the number of visits to the movie theatre

According to the question,

We can write it as:

85 + 8.5x  ≥  153  ------(i)

Now subtract 85 from both the side of equations,

We will get it as follows:

85 + 8.5x - 85 ≥ 153 - 85

8.5x ≥ 68

How do you calculate seed multiplication ratio?

Answers

The number of seeds produced from a single seed when it is sown and harvested is referred to as the seed multiplication ratio.

What is Seed?

A seed is an undeveloped plant embryo and food reserve that is encased in a protective outer covering in botany. More broadly, "seed" refers to anything that can be sown, which could include seed and husk or tuber.

Seeds are the result of a ripened ovule being fertilised by sperm from pollen, resulting in a zygote. The embryo within a seed develops from the zygote, forming a seed coat around the ovule and growing to a certain size within the mother plant before growth stops.

The formation of the seed is a step in the reproduction process of seed plants (spermatophytes). Other plants, such as ferns, mosses, and liverworts, do not have seeds and must reproduce through water-based means.

Is this equation okay to use for the height of the trees in this problem?

There is one equation that is incorrect.... determine which one? why is it incorrectly?

Creat two new equations written in point slope form​

Answers

The equation in option e) is not correct because it would not give correct height of the trees in this problem

How to write equation in slope-point form?

Since the Magnolia trees are 3 feet tall and grow at an average of 3/4 foot per year.

If x is the number of years and y is the height. we can write:

y = 3/4(x) + 3

The slope-point equation of a line is given as:

y-y1 = m(x−x1)

y = 3/4(x) + 3 in slope-point  form is:

y = 3/4(x) + 3

y-3 =  3/4(x-0)

This means option a) is correct

Yes, this equation is okay to use for the height of the trees in this problem

b) y - 6 = 3/4(x-4)

y - 6 = 3/4(x-4)

y - 6 = 3/4(x)- 3

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

y - 3 = 3/4(x)

This is correct

c) y - 4.5 = 3/4(x-2)

y - 4.5 = 3/4(x-2)

y - 4.5 = 3/4(x)- 1.5

y - 4.5 + 1.5 = 3/4(x)

y - 3 = 3/4(x)

This is correct

d) y - 12 = 3/4(x-12)

y - 12 = 3/4(x-12)

y - 12 = 3/4(x) - 9

y - 12 + 9 = 3/4(x)

y - 3 = 3/4(x)

This is correct

(e) y - 15= 3/4(x-15)

y - 15= 3/4(x-15)

y - 15= 3/4(x)-11.25

: Find the pherical coordinate of the point whoe rectangular coordinate are

(-2, 2√3,4)

Answers

The spherical coordinates of the point are (r, θ, φ) = (4√2, -60°, 45°).

What is a peripheral coordinate?

A peripheral coordinate is a set of three coordinates (r, θ, φ) that describes the position of a point in space in relation to a fixed origin. r is the distance from the origin to the point, θ is the angle between the positive x-axis and the projection of the point onto the xy-plane, and φ is the angle between the positive z-axis and the line connecting the point to the origin.

To find the spherical coordinates of a point whose rectangular coordinates are (-2, 2√3,4), we can use the following formulas:

[tex]r=\sqrt{(x^2 + y^2 + z^2)} = \sqrt{((-2)^2 + (2\sqrt3)^2 + 4^2)} = \sqrt{(4 + 12 + 16)} = \sqrt32 = 4\sqrt2[/tex]

θ = [tex]tan^{-1}(y/x) = tan^{-1}(2\sqrt3/(-2)) = tan^{-1}((-\sqrt3)/1) = -60^o[/tex]

φ = [tex]cos^{-1}(z/r) = cos^{-1}(4/4\sqrt2) = cos^{-1}(1/\sqrt2) = \degree 45 ^o[/tex]

So, the spherical coordinates of the point are (r, θ, φ) = (4√2, -60°, 45°).

PLS HELP ME!

Answers

The expression for the sentence that is twice the difference of a number and six is given as follows:

2(n - 6).

How to write the expression?

The sentence for this problem is defined as follows:

"Twice the difference of a number and six."

The number is unknown, hence the variable that represents the number is given as follows:

n.

The difference between the number and six is given by the subtraction of n by 6, as follows:

n - 6.

(the - symbol represents the subtraction).

The expression twice is equivalent to a multiplication of the expression n - 6 by 2, as follows:

2(n - 6).

(the multiplication symbol is implicit before the parenthesis, meaning that the distributive property is applied).

Which is the expression that represents the sentence given at the beginning of the answer.

At Central Middle School the 108 students who take the AMC 8 meet in the evening to talk about problems and eat an average of two cookies apiece. Walter and Gretel are baking Bonnie's Best Bar Cookies this year. Their recipe, which makes a pan of 15 cookies, lists these items: 1/2 cups of flour 2 eggs, 3 tablespoons butter, 3/4 cups sugar 1 package of chocolate drops They will make only full recipes, no partial recipes. They learn that a big concert is scheduled for the same night and attendance will be down 25%. How many recipes of cookies should they make for their smaller party? (Some eggs and some cookies may be left over. )

(A) 1.

(B) 2.

(C) 5.

(D) 7.

(E) 15

Answers

The correct option is option (E) 15

To calculate the number of cookies they will need, they first determine the number of students who will be attending the meeting. Since attendance is down by 25%, the number of students attending is 108*(1-0.25) students.

=108 students * 0.75 = 81 students.

To figure out the number of cookies they will need, they multiply the number of students by the number of cookies per student, which is 81 students * 2 cookies= 162 cookies.

Since each recipe makes 15 cookies, they need to make 162 cookies / 15 cookies/recipe = 10.8 recipes.

Since they cannot make partial recipes, they round up and make 11 recipes of cookies for their smaller party.

As 11 is not a given  option, we consider the option which is greater than 11, which is 15.

The stem-and-leaf plot shows the ages of customers who were interviewed in a survey by a store. How many customers were older than 45

Answers

Customers older than 45 years are 11 in number. This can be solved using stem-and-leaf plot.

What is stem-and-leaf plot?

A stem and leaf plot, often known as a stem plot, is a method for categorizing discrete or continuous data. Data are organized as they are gathered using a stem and leaf plot. A stem and leaf plot resembles a bar graph in appearance. As each integer throughout the database is divided into a stem and a leaf, thus the name fits.

The last digit of each data point serves as the "leaf" in a stem and leaf plot, which divides the data into numerical points (the leading digit or digits).

The stem and leaf plot represents the age of store patrons. The leaf represents the unit digit, while the stem stands for the tens digit. 45 is not taken into account because the question asks us to determine the percentage of consumers who are over 45.

Customers older than 45 years old include: 48, 50, 50, 51, 55, 56, 62, 64, 65, 65, 73.

So, there are a total of 11 clients.
