LAST ATTEMPT IM MARKING AS BRAINLIEST!! (Graph The Image Of The Figure Using The Dilation Given)

Answers

Answer 1

Answer:

\(I(-1,0) \to I \ ' \ (-0.25,0)\\\\J(-1,1) \to J \ ' \ (-0.25,0.25)\\\\K(2,2) \to K \ ' \ (0.5, 0.5)\\\\L(2,-1) \to L \ ' \ (0.5,-0.25)\\\\\)

======================================================

Explanation:

The fraction 1/4 is equivalent to the decimal form 0.25

We multiply 0.25 with each coordinate, of each point.

For example, let's focus on point L which is at (2,-1)

x = 2 becomes x = 0.25*2 = 0.5y = -1 becomes y = 0.25*(-1) = -0.25

Point L(2,-1) moves to L ' (0.5, -0.25) which will move it closer to the origin, which shrinks the image. Use this idea for the remaining points.

Note: this trick only works if the center of dilation is the origin.

Find the nth term of this quadratic sequence
3,8,15,24,35

Answers

The nth term of the given Quadratic Sequence is n² + 2n.

Given, a sequence of numbers i.e. 3, 8, 15, 24, 35

Now, we have to find the nth term of this quadratic sequence

Let, the quadratic sequence be defined as,

f(x) = ax² + bx + c

Now, as we have f(1) = 3

So, a + b + c = 3 ... (1)

also, we have f(2) = 8

So, 4a + 2b + c = 8 ... (2)

also, we have f(3) = 15

So, 9a + 3b + c = 15 ... (3)

On solving Eq (1) & (2), we get

3a + b = 5 ... (4)

also, On solving Eq (3) & (2), we get

5a + b = 7 ... (5)

Now, on solving Eq (4) & (5), we get

2a = 2

a = 1

On substituting the value of 'a' in Eq. (5), we get

b = 2

So, the quadratic sequence be f(x) = x² + 2x.

Hence, the Quadratic Sequence f(x) = x² + 2x and the nth term be

n² + 2n.

For the polynomial below, -3 and -1 are zeros.
g(x)=x² +6x³
+9x²-2x-6
Express g (x) as a product of linear factors.

Answers

The complete factorization of the polynomial is:

h(x) = (x - 3)*(x - 1)*(x + 2)

Here we have the polynomial:

g(x)= x³ - 2x² - 5x + 6

And we know that x = 3 is a zero, then (x - 3) is a factor.

So if f(x) = a*x² + b*x + c

We can write:

h(x) = (x - 3)*f(x)

Let's find f(x).

Expanding that:

x³ - 2x² - 5x + 6 = (x - 3)*(a*x² + b*x + c)

x³ - 2x² - 5x + 6 = ax³ + bx² + cx - 3ax² - 3bx - 3c

x³ - 2x² - 5x + 6 = ax³ + (b - 3a)x² + (c - 3b)x - 3c

Comparing like terms, we can see that:

a = 1

b - 3 a = -2

c - 3b = -5

-3c = 6

With the first and last equation we can get:

a = 1

c = 6/-3 = -2

Now with one of these values and the second or third equation we can find the value of b.

b - 3 a = -2

b - 3*1 = -2

b - 3 = -2

b = -2 + 3 = 1

Then:

f(x)  = x² + x - 2

The zeros of this quadratic function are given by:

x = -1±3 / 2

so, we get,

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

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

Then we can factorize this as:

f(x) = (x - 1)*(x + 2)

And then we can write h(x) as:

h(x) = (x - 3)*(x - 1)*(x + 2)

A hemispherical tank is filled with water and has a diameter of 17 feet. If water weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank, to the nearest pound?

Answers

Answer:

The total weight = 1286 × 62.4 = 80246 pounds.  

Step-by-step explanation:

The formula of the volume of the sphere is

V = 4/3×π×r³

Given

d = 17 feet

as

d = 2r

so

r = d/2 = 17/2 = 8.5 feet

as

V = 4/3×π×r³

Since we need half of the volume as it is a hemispherical tank.

\(\frac{V}{2}=\pi r^3\)

    \(=\frac{2}{3}\times \:3.14\times \:8.5^3\)

    = 1286 ft³

Given that the weighs 62.4 pounds per cubic foot

Thus,

The total weight = 1286 × 62.4 = 80246 pounds.                

The total weight of the water in a full hemispherical tank, which is filled with water, is 80,260 pounds.

What is the volume of hemisphere?

The volume of the hemisphere is the amount of quantity, which is obtained by it in the 3 dimensional space.

The volume of the hemisphere can be calculated with the following formula.

\(V=\dfrac{2}{3}\pir^3\)

Here, {r} is the radius of the hemisphere.

A hemispherical tank is filled with water and has a diameter of 17 feet. The radius of the hemisphere will be half of the diameter. Thus,

\(r=\dfrac{17}{2}\\r=8.5\rm\;ft\)

The volume of the hemispherical tank is,

\(V=\dfrac{2}{3}\pi(8.5)^3\\V=1286.22\rm\; ft^3\)

The water weighs 62.4 pounds per cubic foot. Thus, the total weight of the water in a full tank is,

\(W={1286.22}\times62.4\\W=80260\rm \;pounds\)

Hence, the total weight of the water in a full hemispherical tank, which is filled with water, is 80,260 pounds.

Translate 2 3 y − 9 < y + 1 into a sentence. Nine than two-thirds of number is less than the number .

Answers

The sentence translation of "2/3y - 9 < y + 1" is "Nine less than two-thirds of a number is less than the number."

To translate the inequality expression "2/3y - 9 < y + 1" into a sentence, we can break it down into smaller parts:

"2/3y" represents two-thirds of a number.

"9" represents the number nine.

"y + 1" represents the number increased by one.

Now let's construct the sentence:

"Nine less than two-thirds of a number" - This refers to the expression "2/3y - 9," indicating that we have subtracted nine from two-thirds of a number.

"is less than" - This is the comparison symbol in the inequality.

"the number" - This refers to the expression "y + 1," representing the number increased by one.

Combining these parts, we form the sentence: "Nine less than two-thirds of a number is less than the number."

Hence, the correct sentence translation of "2/3y - 9 < y + 1" is "Nine less than two-thirds of a number is less than the number."

In the second example, the value

In the third example, the value

in the domain is associated with two values in the range, namely

In the fourth example, each of the values in the domain is associated with one value in the range, so this describes a function. Note however that the values

if a city with a population of 500,000 doubles in size every 64 years, what will the population be 256 years from now?

Answers

2,000,000 or 2,000 something 2 hope this helps

Answer:

8,000,000

Step-by-step explanation:

This is because 256 divided by 64 is 4, meaning 64 goes into 256 4 times. If 500,000 is being doubled every 64, it means that in 256 years, the population will have been doubled 4 times.

Meaning? Well...

500,000 x 2 = 1,000,000 = 64yrs

1,000,000 x 2 = 2,000,000 = 128yrs

2,000,000 x 2 = 4,000,000 = 192yrs

4,000,000 x 2 = 8,000,000 = 256yrs

This is 4 times.

so every time it's doubled, it means the sum of that number times 2.

The manager at a restaurant found that the cost to produce 150 cups of coffee is $21, while the cost to produce 300 cups of coffee is $36. assume the relationship between the cost y to produce x cups of coffee is linear.
a.) write a linear equation that expresses the cost,y, in terms of the number of cups of coffee,x.
b.) how many cups of coffee are produced if the cost of production is $56?

Answers

Answer:

\(y = \frac{1}{10}x + 6\)

500 cups cost $56

Step-by-step explanation:

Given

\(x = cups\)

\(y = cost\)

\((x_1,y_1) = (150,21)\)

\((x_2,y_2) = (300,36)\)

Solving (a): Linear Equation

First, we calculate the slope (m)

\(m = \frac{y_2 - y_1}{x_2 - x_1}\)

Substitute right values

\(m = \frac{36 - 21}{300- 150}\)

\(m = \frac{15}{150}\)

\(m = \frac{1}{10}\)

The equation is then calculated as:

\(y = m(x - x_1) + y_1\)

Where

\((x_1,y_1) = (150,21)\)

\(m = \frac{1}{10}\)

This gives:

\(y = \frac{1}{10}(x - 150) + 21\)

Open bracket

\(y = \frac{1}{10}x - \frac{1}{10}*150 + 21\)

\(y = \frac{1}{10}x - 15 + 21\)

\(y = \frac{1}{10}x + 6\)

Solving (b): Cups of coffees for $56

Substitute 56 for y in \(y = \frac{1}{10}x + 6\)

\(56 = \frac{1}{10}x + 6\)

Subtract 6 from both sides

\(-6+56 = \frac{1}{10}x + 6-6\)

\(50 = \frac{1}{10}x\)

Multiply both sides by 10

\(10 * 50 = \frac{1}{10}x * 10\)

\(10 * 50 = x\)

\(500 = x\)

\(x = 500\)

Hence: 500 cups cost $56

What is factoring?

A polynomial expression can be represented as a product of other, smaller polynomial expressions through the algebraic process of factoring. The process of factoring can be used to simplify expressions and solve problems. A polynomial equation's roots can be found by factoring, as can the common factors in an expression that can be eliminated. Factoring occasionally enables us to spot trends and connections between several expressions.

Depending on the kind of polynomial and the degree of the terms involved, there are several ways to factor. S

For the given expression \((12y^7u^2-32y^5u^6+15y^7u^6) / (-4y^2u^5)\) factor the common term.

\((12y^7u^2-32y^5u^6+15y^7u^6) / (-4y^2u^5)\\-4y^5u^2(3y^2 - 8u^4 - 3y^2u^4) / (-4y^2u^5)\)

Cancelling the -4:

\(= y^3 / u^3 (8u^4 - 3y^2u^4 - 3y^2)\)

Hence, the simplified expression is \(y^3 / u^3 (8u^4 - 3y^2u^4 - 3y^2).\)
