Does (–3, –4) also lie on the circle? Identify the radius from the graph. r = __units Determine the distance from the center to (–3, –4) using the distance formula. distance =___ units Compare the radius to the distance. Does the point (–3, –4) also lie on the circle?

Answers

Answer 1
we know thatthe equation of a circle is(x-h)²+(y-k)²=r²where the center is the point (h,k)r is the radius if the center is the originso(h,k) is (0,0)the radius is the distance from point (0,5) to the origin (0,0)r=√[(-5)²+(0)²]-------> r=√25---------> r=5 unitsthe equation is(x-h)²+(y-k)²=r²------------> (x-0)²+(y-0)²=5²----------> (x)²+(y)²=25Does the point (–3, –4) also lie on the circle?the distance from the center to (–3, –4) isd=√[(-4)²+(-3)²]-------> d=√25--------->d=5 unitsd=rthereforethe point (-3,-4) also lie on the circle
Answer 2

The point (–3, –4) does lie on the circle with a center at (0, 0).

We know that the point (0, 5) lies on the circle, and since the center is at (0, 0), the distance from the center to (0, 5) gives us the radius.

Using the distance formula:

radius = √((0 - 0)² + (5 - 0)²)

= √0+25

=√25

= 5 units

So, the radius of the circle is 5 units.

Next, let's determine the distance from the center (0, 0) to the point (–3, –4) using the distance formula:

distance = √ (0- (-3))²+ (0-4(-4))²

= √ 3² + 4²

= √9 +16

= √25

= 5 units

The distance from the center to (–3, –4) is also 5 units.

Since the distance from the center to (–3, –4) is equal to the radius of the circle, the point (–3, –4) lies on the circle.

Therefore, the point (–3, –4) does lie on the circle with a center at (0, 0).

To rationalize the denominator of [tex]\frac{2\sqrt{10} }{3\sqrt{11} }[/tex] you should multiply the expression by [tex]\frac{\sqrt{11} }{\sqrt{11} }[/tex]

Given the surd function:

[tex]\frac{2\sqrt{10} }{3\sqrt{11} }[/tex]

Rationalizing surd functions means multiplying the numerator and denominator of such function by the conjugate of the denominator.

For the surd function given, to rationalize it, we only need to multiply the numerator and denominator by √11 as shown:

[tex]=\frac{2\sqrt{10} }{3\sqrt{11} }\times \frac{\sqrt{11} }{\sqrt{11} } \\=\frac{2\sqrt{110}}{3(11)}\\= \frac{2\sqrt{110}}{33}\\[/tex]

When the maximum value in a data set is exchanged for a higher

summary?​

Answers

Answer:

It doesn't change any of the other numbers of the five number summary. Only the maximum value of the data set changes, out of the five number summary of the data set.

Step-by-step explanation:

The five number summary of any data set consists of five values which includes

- The maximum value of the data set.

- The minimum values.

- The lower quartile.

- The upper quartile.

- The median.

These values are usually presented together and ordered from lowest to highest: minimum value, lower quartile (Q1), median value (Q2), upper quartile (Q3), maximum value.

Replacing the maximum value with a higher number doesn't change any of the other five number summary as they all position markers, whose values do not change because of changes at one end of the distribution as the positions of the other variables n the dataset are untouched.

This means that, of the five number summary, only the maximum value of the data set changes.

Although, values like the range, mean and standard deviation also change too.

Hope this Helps!!!

There is no change in any of the other numbers of the five number summary.

Only the maximum value of the data set  is changed.

Kerri attends a 40-minute yoga class 5 times per week. How much time does she spend in the yoga class over a 7-week period?

Answers

Answer:

1,400 minutes

Step-by-step explanation:

First, let’s find how much time she spends per week.

She attends a class that is 40 minutes long and she does this 5 times a week.

Therefore, we can multiply 5 and 40 to find the total time per week.

5*40

200

She spends 200 minutes per week and she does this over a 7 week period.

We can multiply 200 and 7

200*7

1,400

She spends 1,400 minutes in yoga class over a 7 week period.

Answer:

1,400 minutes.

Step-by-step explanation:

Kerri attends a 40-minute yoga class 5 times per week.

Multiply 40 by 5 to get the total minutes for one week:

[tex]40*5=200[/tex]

So, Kerri attends yoga classes for 200 minutes total for one week.

With that in mind:

Step-by-step explanation:

i add them

first i find the common denominator for 1/6 and 1/8

then i add 13.50 by 5

then add 18.50 by 7/24

i hope this explains how i got my answer

Answer:

Total amount of $ at beginning of day ⇒ ( About ) $ 26.1

Step-by-step explanation:

Let us say x represents ⇒ amount of $ at the beginning of the day;

If she spent 1 / 6 of this total money on books, we can say that the amount spent on books is 1/6x. Consecutively if 1/8 of this money was spent on shoes, the amount spent on shoes is 1/8x;

Knowing that $13.50 was remaining, let us set up the following equation;

x - ( 1/6x + 1/8x + 5 ) = 13.50 ⇒ now let us solve for x,

x - ( 1/6x + 1/8x + 5 ) = 13.50 ⇒ add similar elements, expanding,

x - ( 7/24x + 5 ) = 13.50 ⇒ distribute the minus sign

x - 7/24x - 5 = 13.50 ⇒ multiply either side by 24,

17x - 120 = 324 ⇒ add 120 to either side,

17x = 444,

Solution; Total amount of $ at the beginning of day ⇒ ( About ) $ 26.1

If the expression f^2+g^4-2f+1 is rewritten in the form a^2+(g^2)^2, what must be the value of a?

Answers

Answer: √(f^2 - 2f + 1) = a

Step-by-step explanation:

We have that:

f^2+g^4-2f+1 =  a^2+(g^2)^2

And we want to find the value of a, so we should isolate it.

f^2 + g^4  - 2f + 1 = a^2 + g^(2*2) = a^2 + g^4

where i used that (x^y)^z = x^(y*z)

We can remove the term g^4 in both sides of the equation and get:

f^2 - 2f + 1 = a^2

now we can apply the square rooth to both sides and get

√(f^2 - 2f + 1) = a

So we just found the value of a.

Write the equation of the graph which is the reflection of y=−|x−1|−1 about the origin

Answers

Answer:

f(x) = |x + 1| + 1

Step-by-step explanation:

A reflection over the y-axis followed by a reflection over x-axis is equivalent to a reflection about origin.

f(x) = -|x-1| -1

reflection over the x-axis:

-f(x) = (-1)*(-|x-1| -1) = |x-1| +1

reflection over the y-axis of the previous function:

-f(-x) = |-x-1| +1 = |x + 1| + 1

which is the reflection of f(x) about the origin

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best explains whether the company can build 5 child bikes and 15 adult bikes in the week.

No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Answers

Answer:

Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Step-by-step explanation:

4c + 6a ≤ 120:

You can set up the inequality 4c + 6a ≤ 120, because it takes 4 hours to build per child bike (c) and 6 hours to build an adult bike (a), all together this time cannot surpass 120 hours. That is why you use the 'less than or equal to' sign.

4c + 4a ≤ 100:

You can then set up the inequality 4c + 4a ≤ 100, because it takes 4 hours to test a child bike (c) and 4 hours to test an adult bike (a). Since 100 hours is the max amount of time they can use to test out bikes, you will use the 'less than or equal to' sign.

4(5) + 6(15) = 20 + 90 = 110. 110 is less than 120

4(5) + 4(15) = 20 + 60 = 80. 80 is less than 100

Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

The following graph represents the hourly commission of a home appliance salesperson, y, based on the number of salespeople that are
working the showroom floor, x. The graph of the hourly commission of the salesperson is a quadratic function. What is the equation for
the function in standard form if the vertex is 6.5,42.25 and the origin is the only other known point?

Answers

We have been given graph of a downward opening parabola with vertex at point [tex](6.5,42.25)[/tex]. We are asked to write equation of the parabola in standard form.

We know that equation of parabola in standard form is [tex]f(x)=ax^2+bx+c[/tex].

We will write our equation in vertex form and then convert it into standard form.

Vertex for of parabola is [tex]y=a(x-h)^2+k[/tex], where point (h,k) represents vertex of parabola and a represents leading coefficient.

Since our parabola is downward opening so leading coefficient will be negative.

Upon substituting coordinates of vertex and point (0,0) in vertex form, we will get:

[tex]0=-a(0-6.5)^2+42.25[/tex]

[tex]0=-a(42.25)+42.25[/tex]

[tex]-42.25=-a(42.25)+42.25-42.25[/tex]

[tex]-42.25=-42.25a[/tex]

[tex]a=1[/tex] Divide both sides by [tex]-42.25[/tex]

So our equation in vertex form would be [tex]f(x)=-(x-6.5)^2+42.25[/tex].

Let us convert it in standard from.

[tex]f(x)=-(x^2-13x+42.25)+42.25[/tex]

[tex]f(x)=-x^2+13x-42.25+42.25[/tex]

[tex]f(x)=-x^2+13x[/tex]

Therefore, the equation of function is standard form would be [tex]f(x)=-x^2+13x[/tex].

Having found such a person, the problem does not end here. A big goat may worth not only one book, hence person B may have to offer person A something else, say five chickens. However, he runs the risk of person A rejecting the offer as he may not need the chickens. The above example clearly illustrates the inefficiency of barter trading. Many years later, the cumbersome barter trade finally gave way to the monetary form of exchange when the idea of money was invented. In the early days, almost anything could qualify as money: beads, shells and even fishing hooks. Then in a region near Turkey, gold coins were used as money. In the beginning, each coin had a different denomination. It was only later, in about 700 BC, that Gyges, the king of Lydia, standardized the value of each coin and even printed his name on the coins. Monetary means of transaction at first beat the traditional barter trade. However, as time went by, the thought of carrying a ponderous pouch of coins for shopping appeared not only troublesome but thieves attracting. Hence, the Greek and Roman traders who bought goods from people faraway cities, invented checks to solve the problem. Not only are paper checks easy to carry around, they discouraged robbery as these checks can only be used by the person whose name is printed on the notes. Following this idea, banks later issued notes in exchange for gold deposited with them. These bank notes can then be used as cash. Finally, governments of today adopted the idea and began to print paper money, backed by gold for the country's use. Today, besides enjoying the convenience of using paper notes as the mode of exchange, technology has led man to invent other means of transaction too like the credit and cash cards A quantity of Lithium reacts with sulfuric acid (H2SO4) to produce .10 g of hydrogen.
