Answer 1

Answer:

[tex]y' = (6,4)[/tex]

Step-by-step explanation:

Given

[tex]y = (3,2)[/tex]

[tex]x = (4,0)[/tex]

[tex]z = (2,-2)[/tex]

[tex]D_{(O,2)}[/tex]

Required

The image of y

[tex]D_{(O,2)}[/tex] implies that y is dilated by a scale factor of 2 across the origin.

So, the image of y is:

[tex]y' = 2 * y[/tex]

[tex]y' = 2 * (3,2)[/tex]

[tex]y' = (6,4)[/tex]

Answer: answer is -4 5/12

Step-by-step explanation:

Answer:

-4 - 5/12, or option 3.

Step-by-step explanation:

Change the denominator of each fraction to a common denominator. In this situation, the common denominator between the three fractions is 12.

- 7 2/3 = - 7 8/12

- 5 1/2 = - 5 6/12

8 3/4 = 8 9/12

Add them together.

-7 8/12 - 5 6/12 + 8 9/12 =

First, add the whole numbers together.

-7 - 5 + 8 - 8/12 - 6/12 + 9/12 =

-12 + 8 - 8/12 - 6/12 + 9/12 =

-4 - 8/12 - 6/12 + 9/12 =

Now, add the numerators of the fractions together.

-4 + (-8 -6 + 9)/12

-4 + (-5)/12 =

-4 - 5/12

The answer is -4 - 5/12, or option 3.

A bank loaned out $15,000, part of it at the rate of 7% per year and the rest at 17% per year. If the interest received in one year totaled $2000, how much was loaned at 7%?
How much of the $15,000 did the bank loan out at 7%?

Answers

9514 1404 393

Answer:

$5,500

Step-by-step explanation:

Let x represent the quantity loaned at 7%. Then the amount loaned at 17% is (15000-x), and the total interest is ...

0.07x +0.17(15000 -x) = 2000

-0.10x = -550 . . . . . . . . . collect terms, subtract 2550

x = -550/-0.10 = 5500 . . . . divide by the coefficient of x

The bank loaned $5,500 at 7%.

850 horses and cows

Answers

Question :-

A farmer had 305 horses and 454 cows. Which of the following is a good estimation of how many horses and cows he had altogether?

600 horses and cows

700 horses and cows

650 horses and cows

750 horses and cows

850 horses and cows

____________________

Solution :-

Given Information :-

Number of horses ➢ 305Number of cows ➢ 454

To Find :-

Which of the following is a good estimation of how many horses and cows he had altogether?

600 horses and cows

700 horses and cows

650 horses and cows

750 horses and cows

850 horses and cows

Calculation :-

Here, We will simply add up the number of animals ( cows and horses ) and then we will round it off to it's nearest 'tens' places.

⇒ Total number of animals = number of horses + number of cows

Substituting the values given, We get,

⇒ Total number of animals = 305 + 454

⇒ Total number of animals = 759

Now, when we round it off to it's nearest 'tens' places, We get,

⇒ Round off 759 = 750

Since, We can see that, 4th option from the list of option given, is 750. Therefore 750 is the answer.

____________________

Final Answer :-

4th option :- 750 horses and cows is the correct answer.

in a rectangle ABCD in the figure shown ,what are the coordinates of vertex c

note : the figure shown in the image attached

helppppppp

Answers

Answer:

E. (7, 5)

Explanation:

vertices C and D have the same coordinate x and x of D = 7

hence

x of C = 7

vertices A and D have the same coordinate y and y of D = 2

hence

m = 2

and

m+3 = 2+3 = 5

and since vertices B and C have the same coordinate y and y of B = 5

hence

y of C = 5

thus

coordinates x, y of C: (7, 5)

what is 49.50 rounded to the nearest hundredth?
what is 51.10 rounded to the nearest hundredth?
what is 30.00 rounded to the nearest hundredth?

Answers

Step-by-step explanation:

The hundredth place is the second number to the right of the decimal place (e.g., in ab.cd, where a, b, c, and d represent digits, the hundredth place is d).

When we round to the nearest hundredth, we remove all digits after the thousandth place. Then, if the thousandth place is 5 or greater, we remove it and add 0.01 (round up); if the thousandth place is 4 or lesser, we remove it (round down).

Thus:

50.30=50.30, as there is no thousandth place

50.20=50.20, same reasoning

56.90=56.90, same reasoning

49.50=49.50, same reasoning

51.10=51.10, same reasoning

30.00=30.00, same reasoning

Which term of series1 +4+7+10+...is43

Answers

Answer:

a = 4

d = a2 - a1

d = 7 - 4

d = 3

an = 43

an = a + (n - 1)d

43 = 4 + (n - 1) 3

43 = 4 + 3n - 3

43 = 1 + 3n

43 - 1 = 3n

3n = 42

n = 42 ÷

n = 14

So, 14th term is 43

What is its domain?
What is its range?

Write the answer in interval notation.

Answers

Answers:

Domain = [-3, 3]

Range = [-1, 2]

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

Explanation:

The domain is the set of all allowed x inputs. Visually, the left-most point is when x = -3, so -3 is the smallest allowed x input. We have a closed circle at this endpoint, so this endpoint x value is included. In contrast, if you had an open circle, then you would exclude the endpoint.

Similarly, we have a closed endpoint at the other side as well when x = 3. This is the largest allowed x value. The domain is the set of x values such that [tex]-3 \le x \le 3[/tex] meaning x is between -3 and 3, including both endpoints. This translates to the interval notation of [-3, 3]. The square brackets say "include the endpoint".

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

The range is the set of possible y outputs of a function. The lowest the function goes is when y = -1, and the highest is when y = 2. We include both endpoints. The range as a compound inequality is [tex]-1 \le y \le 2[/tex] which converts to the interval notation of [-1, 2]
