Describe The Dilation Needed To Map Each Pre-image Onto Each Image.

Answers

Answer 1

Answer:

(1)- 1/3  (2)- 2  (3)- 1/2   (4)-  4.

Step-by-step explanation:

We have been given four images and their pre-images and we are asked to find out the factor of dilation.

(1) We have been given a triangle ABC, whose center of dilation is A. In order to find out factor of dilation we will see lengths of two corresponding sides. AB is 6 units long and A'B' is two units long. To map triangle ABC on triangle A'B'C' we have to dilate triangle ABC by a factor of 1/3 as 2 is 1/3 of 6.

Therefore, factor of dilation is 1/3.

(2) Let us find the lengths of two corresponding sides of our image and pre-image. Side ST is 6 units long and S'T' is 12 units long. To map our image of quadrilateral on pre-image we have to dilate our image by a factor of 2 as S'T' is 2 times of ST.

Therefore, factor of dilation is 2.

(3) Side QR is 6 units long and its corresponding side Q'R' is 3 units long. We can see that Q'R' is 1/2 of QR so in order to map our triangle QRS on triangle Q'R'S' we have to dilate our pre-image by a factor of 1/2.

Therefore, our factor of dilation is 1/2.

(4) Length of side AB of our image is 2 units and A'B' is 8 units long. 8 is 4  times 2. To map our pre-image ABC on our image A'B'C' we have to dilate our mage by a factor of 4.

Therefore, factor of dilation is 4.

simplify (2 x 10^3) (4 x 10^-5)

Answers

the answer to this problem is 2/25. I got this by simplifying both exponents which changes the equation to (2)(1000)(4)(1/100000). Then you multiply the other numbers by its simplified exponent and makes the equation 2000(1/25000). The last step is to multiply those two and you get your answer, 2/25(simplified version)   :)

Final answer:

To simplify (2 x 10^3) (4 x 10^-5), you multiply the numbers 2 and 4 to get 8 and add the exponents +3 and -5 to get -2, giving the final result of 8 x 10^-2.

Explanation:

To simplify the expression (2 x 10^3) (4 x 10^-5), you need to multiply the numbers (2 and 4) and the exponents of 10 (+3 and -5) separately. To multiply 2 and 4, you get 8. When multiplying numbers with exponents, you add the exponents together. So, 10^3 multiplied by 10^-5 is the same as 10^(3 - 5), or 10^-2. So the answer is 8 x 10^-2.

f(x) = 1 x g(x) = x − 4 Can you evaluate (g ○ f)(0)? Explain why or why not.

Answers

Answer:

To evaluate the composition, you need to find the value of function f first. But, f(0) is 1 over 0, and division by 0 is undefined. Therefore, you cannot find the value of the composition.

Step-by-step explanation:


NO, because the resulting function for (g ○ f)(0) tends to infinity

An undefined term or function is a term or function that does not exsit.

A composite function is a function that is placed in another function.

Given the functions

f(x) = 1/x g(x) = x − 4

Before we can calculate the composite function (g ○ f)(0), we ned to first calculate (g ○ f)(x) as shown:

(g ○ f)(x) = g(f(x))

g(f(x)) = g(1/x)

Substitute x as 1/x in g(x) as shown:

[tex]g(f(x)) =g(\frac{1}{x} )\\g(\frac{1}{x} )=(\frac{1}{x}-4 )\\Find \ the \ LCM\\g(\frac{1}{x} )=(\frac{1-4x}{x} )\\[/tex]

NExt is to check whether we can evaluate (g ○ f)(0) by substituting x = 0 into the resulting function as shown:

[tex]g(f(0) )=(\frac{1-4(0)}{0} )\\g(f(0) )=(\frac{1}{0} )\\g(f(0) )=\infty[/tex]

We can see that the resulting function tends to infinity which shows that g ○ f)(0) cannot be evaluated.

How do you convert a fraction or decimal to a degree?

Answers

Final answer:

To convert a fraction or decimal to a degree, convert the fraction to a decimal if necessary, and then multiply by 360 to get the degree measurement.

Explanation:

The question is about how to convert a fraction or decimal to a degree, which is fundamentally a process of unit conversion. While the base information provided relates to converting decimals to percents and vice versa, converting to degrees requires a different approach.

To convert a decimal to a degree, you need to understand that one whole turn (360 degrees) equals a value of 1 in decimal form. If you have a decimal, you simply multiply it by 360 to get the degree measure. For a fraction, you convert it to a decimal by dividing the numerator by the denominator and then multiply by 360 to convert to degrees.

For example, to convert the fraction 1/2 to degrees, first convert it to a decimal (1 divided by 2 equals 0.5), then multiply by 360 to get 180 degrees. Similarly, to convert the decimal 0.25 to degrees, you would multiply 0.25 by 360 to get 90 degrees.

given -2(x + 1) = 5x + 4 - x ( distribute left side )

-2x - 2 = 4x + 4 ( simplifying both sides )

subtract 4x from both sides

- 6x - 2 = 4 ( add 2 to both sides )

- 6x = 6 ( variable by itself on left side )

divide both sides by - 6

x = [tex]\frac{6}{-6}[/tex] = - 1

as a check, substitute x = - 1 into the equation and if both sides are equal then it is the solution.

left side = - 2(-1 + 1 ) = - 2 × 0 = 0

right side = (5 × - 1) + 4 - (- 1) - 5 + 4 + 1 = 0

Ruben has 6 new books for his collection. This increases his collection by 12%? How many books does he have now?

Answers

Ruben has 6 new books for his collection. This increases his collection by 12%

Let x be the number of books Ruben has before 6 new books added

x + 12% of x = x+6

x + 0.12x = x+6

1.12 x = x+6

Subtract x on both sides

0.12x = 6

Divide by 0.12

x = 50

6 new books are added for his collection

So 50 + 6 = 56

He have 56 books now.

The idea of distribution is to multiply the outer value 0.5 by each of the values inside the parenthesis (0.5, 0.3, and 0.2) and add up the products.

Equation C and D that is (0.5⋅0.5)+(0.5⋅0.3)+(0.5⋅0.2)=0.5⋅(0.5+0.3+0.2) and 0+1.015=(50⋅1)+(50⋅0.01)+(50⋅0.005) ​applies the distributive property correctly as defined "multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together".

What is distributive property?

The distributive law, which states that in elementary algebra, equality is always true, is generalized by the distributive property of binary operations. For instance, in basic mathematics, one has to According to one, addition is distributed more evenly than multiplication. In order to quickly solve expressions, a number is distributed among the numbers in the brackets. When using the distributive property of multiplication, for instance, to resolve the expression 4(2 + 4), we would do so as follows: 4(2 + 4) = (4 × 2) + (4 × 4) = 8 + 16 = 24.

Final answer:

Using the information that Ram is twice as old as Sheeta and that five years ago his age was three times the age of Sheeta, we solve the equation 2S - 5 = 3(S - 5) to find that Sheeta's current age is 10 years old.

Explanation:

The question involves creating equations based on the given information to solve for Sheeta's age. Let's denote Sheeta's age as 'S' and Ram's age as '2S' since Ram is twice as old as Sheeta. According to the second statement, five years ago Ram's age was three times Sheeta's age at that time. Therefore, we can write the equation as 2S - 5 = 3(S - 5).

Solving the equation step-by-step:
