The center of a circle is located at (3.8), and the circle has a radius that is 5 units long. What is the general form of the equation for the circle?

Answer: f(x) = -3| x - 1 |  is really just  f(x) = -3| x - 1 | + 0.

now, what value of "x" makes the absolute value expression to 0?

well, let's just set it to 0 and check,

x - 1 = 0

x = 1

so if "x" ever becomes 1, the | x - 1| will turn to 0, therefore, the vertex is at   

f(x) = -3| (1) - 1 | + 0  -------------->  ( 1, 0 )

Answer:

City's Area = 507.44 sq. mi.

Step-by-step explanation:

We will use population density formula to solve this problem easily.

We have:

Population Density = Total Population/ Land Area

Given,

Population Density = 24,403

Total Population = 12,383,007

We want land area, so we simply plug in the numbers into the formula and solve for City's Area. Shown below:

[tex]Population  \ Density = \frac{Total \ Population}{Land \ Area}\\24,403=\frac{12,383,007}{Land \ Area}\\Land \ Area = \frac{12,383,007}{24,403}\\Land \ Area = 507.44[/tex]

THe units is Square Miles, so we can say:

City's Area = 507.44 sq. mi.

Step-by-step explanation:

$5 off is well $5 off so, we would be paying $45 for the item. If we took 25%, thats $12.50 therefore you would only pay $37.50. So the 25% saves you $7.50 so it si false. $5 is a worse deal.

Answer:

-7/48 in

Step-by-step explanation:

Assuming that the movement varies linearly with time,

3 years ------> -7/16 in

1 year -------> -7/16 ÷ 3 = -7/48 in

Independent. Two events are dependent if knowing the result of the first one influences what you'd expect from the second.

Consider this example: if I have a sack with 3 black marble and 1 white marble, I have probability 75% of picking a blakc marble, and 25% of picking the white one.

If I pick the white one, and don't replace, the second pick will be dependent on the first one, because now I'm sure that I'll pick one of the black marbles, since they are the only ones left in the sack.

In your example, though, Wendy replaces the marble she picks first. This means that the second pick will take place in the exact same conditions of the first one, and knowing which marble she picked at first doesn't affect in any way the result of the second pick.

As another example, consider rolling two dice. Suppose that the first die lands showing 4. Does this affect in any way what you'd expect from the second die? Well, no: the numbers 1-6 are still equally probable to show up.

Answer:

A) 1/4 min

Step-by-step explanation:

Find the equation for the graph:

y = mx + b

Find the slope using two random points (0, 360) and (5, 0)

m = (y2 - y1) / (x2 - x1)

m = (0-360) / (5-0)

m = -360/5

m = -72

b is 360, the y-intercept.

Substitute m= -72 and b=360 into slope-intercept form.

y = -72x + 360

x represents time and y represents the total amount of water at the time.

We are looking for when only 18 liters were drained.

360 - 18 = 342  <= Total amount of water when 18 liters are drained

Substitute 342 for y in the equation and isolate x.

342 = -72x + 360

-18 = -72x

x = 18/72

x = 1/4

Therefore, it will take 1/4 of a minute to drain 18 liters.

Answer:

Simple interest = PRT/100

1380 = P x 12 x 2/100

138000 = 24P

Therefore P = 5750 Rs.

Hope this helps!

To find the principal amount given the simple interest, rate, and time, use the formula P = SI / (R × T). Substituting the values, the principal amount is 5750 rupees.

To find the sum of money (principal) using the given simple interest, we can use the simple interest formula:

Simple Interest (SI) = Principal (P) × Rate (R) × Time (T)

Here, we know that:

Rearranging the formula to solve for the principal (P):

[tex]P = \frac{SI }{(R * T)}[/tex]

Substitute the known values:

P = 1380 / (0.12 × 2)

Solving the equation:

P = 1380 / 0.24

P = 5750 rupees

Therefore, the sum of money is 5750 rupees.

Answer:

The correct answer is that AC = 4x - 2 or 2(2x - 1)

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

AD = 6x + 10

CD = 2x + 12

2. Let's find the length of AC

AC = AD - CD

Replacing with the real values:

AC = (6x + 10) - (2x + 12)

AC = 6x + 10 - 2x - 12

AC = 6x - 2x + 10 - 12

AC = 4x -2 or 2(2x - 1)

Answer:

x=1+/-4i

Step-by-step explanation:

(x+1)/3-(2x-1)/x=-1

find the common denominator,

in this case, it's going to be 3x.

(x^2+x)/3x-(6x-3)/3x=-1

(x^2+x-6x+3)/3x=-1

x^2-5x+3=-3x

x^2-5x-(-3x)+3=0

x^2-5x+3x+3=0

x^2-2x+3=0

apply the quadratic formula in order to find the roots for x.

Since ax^2+bx+c=0, in this case,

a=1, b=-2, c=3

--------------------------

x=(-b+/-sqrt(b^2-4ac))/2a

x=(2+/-sqrt(4-12))/2

x=(2+/-8i)/2

x=1+/-4i

To Find: If each student on average took up a circular space with a diameter of [tex]2.5[/tex] ft what is the best estimate for the number of  students at the pep rally.

Solution:

Consider the figures attached

A student took up a circular space, if they were packed in rows each student acquired a circular space of [tex]2.5[/tex] ft and left some unused area as given in figures

Now,

Area acquired by a student is a square of side [tex]2.5[/tex] ft as given in figure

Area acquired by single student[tex]=(\text{length of square})^2[/tex]

                                                     [tex]=2.5\times2.5[/tex]

                                                     [tex]6.25\text{sq.ft}[/tex]

Total number of students            [tex]=\frac{\text{total area of rectangular gym}}{\text{area acquired by single student}}[/tex]

                                                     [tex]\frac{7500}{6.25}[/tex]

                                                     [tex]1200[/tex]

Answer: 26

Step-by-step explanation:

30-17=13

13+13=26

Answer:

26 boi

Step-by-step explanation:

1. 4(2+3c) = 56

c = 4

3. -29 = 5(2a-1)+2a

a = -2

5 . 7p-(3p+4) = -2(2p-1)+10

p=2

7. 1/2 (-4+6x) = 1/3x + 2/3*(x+9)

x=4

Step-by-step explanation:

1. 4(2+3c) = 56

[tex]4(2+3c) = 56\\8+12c = 56[/tex]

Subtracting 8 from both sides

[tex]8-8+12c = 56-8\\12c = 48[/tex]

Dividing both sides by 12

[tex]\frac{12c}{12} = \frac{48}{12}\\c = 4[/tex]

Checking:

[tex]4[2+3(4)] = 56\\4(2+12) = 56\\4(14) = 56\\56 = 56[/tex]

3. -29 = 5(2a-1)+2a

Simplifying

[tex]-29 = 10a-5+2a\\-29 = 12a-5[/tex]

Adding 5 on both sides

[tex]-29+5 = 12a - 5+5\\-24 = 12a[/tex]

Dividing both sides by 12

[tex]\frac{12a}{12} = \frac{-24}{12}\\a = -2[/tex]

Checking:

[tex]-29 = 5(2a-1)+2a\\-29 = 5[2(-2)-1]+2(-2)\\-29 = 5(-4-1) -4\\-29 = 5(-5) -4\\-29 = -25-4\\-29 = -29[/tex]

5 . 7p-(3p+4) = -2(2p-1)+10

Simplifying

[tex]7p-3p-4 = -4p+2+10\\4p-4 = -4p+12[/tex]

Adding 4 on both sides

[tex]4p-4+4 = -4p+12+4\\4p = -4p+16[/tex]

Adding 4p on both sides

[tex]4p+4p = -4p+4p+16\\8p = 16[/tex]

Dividing both sides by 8

[tex]\frac{8p}{8} = \frac{16}{8}\\p = 2[/tex]

Checking:

[tex]7p-(3p+4) = -2(2p-1)+10\\7(2)-[3(2)+4] = -2[2(2)-1] +10\\14 - (6+4) = -2 (4-1) +10\\14 - 10 = -2(3) +10\\4 = -6+10\\4=4[/tex]

7. 1/2 (-4+6x) = 1/3x + 2/3*(x+9)

Simplifying

[tex]\frac{1}{2} (-4+6x) = \frac{1}{3}x+\frac{2}{3}(x+9)\\\frac{-4}{2}+\frac{6x}{2} = \frac{x}{3} +\frac{2x}{3} + \frac{18}{3}\\-2+3x = \frac{x+2x+18}{3}\\-2+3x = \frac{3x+18}{3}\\3(-2+3x) = 3x+18\\-6+9x = 3x+18[/tex]

Adding 6 on both sides

[tex]-6+6+9x = 3x+18+6\\9x = 3x+24[/tex]

Subtracting 3x from both sides

[tex]9x-3x = 3x-3x+24\\6x = 24[/tex]

Dividing both sides by 6

[tex]\frac{6x}{6} = \frac{24}{6}\\x = 4[/tex]

Checking:

[tex]\frac{1}{2} [-4+6(4)] = \frac{1}{3}(4)+\frac{2}{3}(4+9)\\\frac{1}{2}(-4+24) = \frac{4}{3}+\frac{2}{3}(13)\\\frac{1}{2}(20) = \frac{4}{3} +\frac{26}{3}\\15 = \frac{4+26}{3}\\15 = \frac{30}{3}\\15=15[/tex]

Answer:

Henry uses 36 nails in large bookshelves and 52 nails in small bookshelves.

Step-by-step explanation:

Let in each large bookshelves Henry uses x nails and in each small bookshelves, Henry uses y nails.

Now, he built 10 small bookshelves and 1 large bookshelf, using a total of 412 nails.

So, 10x + y = 412 ......... (1)  

Again, he built 10 small bookshelves and 8 large bookshelves, using a total of 776 nails.

So, 10x + 8y = 776 ........... (2)

Now, subtracting equation (1) from equation (2) we get, 7y = 364

⇒ y = 52

Again, from equation (1) we get, 10x = 412 - 52 = 360

⇒ x = 36

Therefore, Henry uses 36 nails in large bookshelves and 52 nails in small bookshelves. (Answer)

Final answer:

Henry uses 36 nails for a small bookshelf and 52 nails for a large bookshelf, according to the system of equations derived from the information given.

Explanation:

Calculating the Number of Nails Used by Henry

To solve this problem, we will use a system of equations.
Let's define x as the number of nails used for a small bookshelf and y as the number of nails used for a large bookshelf. From the question, we have the following equations based on the information given:

10x + 1y = 412 nails (first scenario with 10 small and 1 large bookshelf)

10x + 8y = 776 nails (later scenario with 10 small and 8 large bookshelves)

We can use these two equations to find out the values of x and y. Let's subtract the first equation from the second to eliminate x from our calculations:

10x + 8y − (10x + 1y) = 776 − 412
7y = 364
y = 52

Now we know that Henry uses 52 nails for a large bookshelf. Next, we will find the number of nails for a small bookshelf by substituting the value of y into the first equation:

10x + 1(52) = 412
10x = 412 − 52
10x = 360
x = 36

Hence, Henry uses 36 nails for a small bookshelf.

Answer:

3

Step-by-step explanation:

According to the Triangle Inequality Theorem, the sum of any 2 sides of any triangle must be greater than the length of the third side. That is:

AB + BC > AC and AB + AC > BC and AC + BC > AB

So in this case:

if AC + AB > BC

x + 12 > 15

After substracting 12 from each side of the equation, we get that:

x > 3

Hence, the value of x must be greater than 3.

Answer:

Here we have to use the Triangle Inequality Theorem, because the problem it's asking about the restriction of one side, with two sides given. This theorem, in words, states that the sum of the minor sides is more than the length of the major sides of all three. So, if we translate this to equation, we have:

[tex]AB + BC > AC[/tex]

Where [tex]AB=12[/tex]; [tex]BC=x[/tex] and [tex]AC=15[/tex]

Assuming that [tex]AC[/tex] is the longest side we applied the theorem to this problem. Now, replacing all values we have:

[tex]12+x>15\\x>15-12\\x>3[/tex]

Therefore, the unknown side must be greater than 3 to not violate the Triangle Inequality Theorem, which is always true about every triangle.

The school net ball team drew 2 matches. The team won [tex]\frac{5}{8}[/tex] of total matches played

Given, A school netball team won ten matches, lost four and drew [tex]\frac{1}{8}[/tex] of the total played

Let the total number of matches played be "n"

Number of matches drawn = [tex]\frac{1}{8}[/tex] of n

Total matches played = number of won matches + number of lost matches + number of drawn matches

[tex]\begin{array}{l}{n=10+4+\frac{1}{8} n} \\\\ {n-\frac{1}{8} n=10+4}\end{array}[/tex]

Taking "n" as common from left hand side,

[tex]\begin{array}{l}{\mathrm{n}\left(1-\frac{1}{8}\right)=14} \\\\ {\mathrm{n} \times \frac{8-1}{8} \quad 14} \\\\ {\mathrm{n} \times \frac{7}{8}=14} \\\\ {\mathrm{n}=16}\end{array}[/tex]

So, they played 16 matches in total

Number of matches drawn = [tex]\frac{1}{8}[/tex] of n = [tex]\frac{1}{8} \times 16 = 2[/tex][tex]\text { Fraction of won matches }=\frac{\text { number of matches won }}{\text { number of matches played }}=\frac{10}{16}=\frac{5}{8}[/tex]

Answer:

6x - 3

Step-by-step explanation:

Distribute first.

4x + 6x - 3 - 4x = 10x - 4x - 3 = 6x - 3

The equivalent expression for 4x + 3(2x - 1) - 4x is 6x - 3, achieved by distributing the multiplier in the parenthese and then combining like terms.

The expression 4x + 3(2x - 1) - 4x can be simplified by first distributing the 3 in the term 3(2x - 1), then combining like terms.

1. Distribute the 3 to get : 4x + 6x - 3 - 4x

2. Combine like terms: 6x - 3

So, the equivalent expression of 4x + 3(2x - 1) - 4x is 6x - 3
