Which translation maps the graph of the function f(x) = x2 onto the function g(x) = x2 + 2x + 6? left 1 unit, up 5 units right 1 unit, up 5 units left 2 units, up 2 units right 2 units, up 2 units

Answers

Answer:

  1. Shift left by 1 unit
  2. Shift up by 5 units  

Step-by-step explanation:

In order to answer this question first we have to convert g(x) into vertex form.

g(x)=x^(2)+2x+6\ng(x)=x^(2)+2(x)(1)+(1)^(2)+5\ng(x)=(x+1)^(2)+5

Now from this form we can visualize the transformations made to f(x) to get the graph of g(x).

Addition of 2 in x means that graph of f(x) = x2 is shifted 1 unit to left to get (x + 1)² .

Addition of 5 in the function value indicates that the graph is shifted 5 units up.

So the changes which have been made to f(x) in order to get g(x) are:

  1. Shift left by 1 unit
  2. Shift up by 5 units

12 ten thousands is 120,000
8 thousand is 8,000
14 hundreds is 1,400
there are no tens
7 ones is 7
so 120,000+8,000+1,400+7=129,407

Decrease £180 by 12.5%

Answers

The result after decreasing 180 by 12.5% of its value is 157.5

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100.

What is Subtraction?

Subtraction is an arithmetic operation that represents the operation of removing objects from a collection.

Given,

The value = 180

12.5% of 180 = 180((12.5)/(100))=22.5

Subtraction

180 - 22.5 = 157.5

Hence, the result after decreasing 180 by 12.5% of its value is 157.5

Answer:

The answer is £157.5.

Step-by-step explanation:

Another way of decreasing by a percentage is to increase by that percentages compliment.

Since 100-12.5 = 87.5%. We can increase 180 by 87.5% to get the same result.

0.875*180 = 157.5

_______________________item | cost |

----------------------------------------
Darryl places an order for 128 ounces of pickles, 24 loaves of bread, and 25 pounds of coffee. What is the total cost of the order?
please hurry!

Answers

To get the answer we have to multiply number of products times cost of 1 (oz/loaf/pound) and add it together.
pickles
128*0.20=25.6
bread
24*0.75=18
coffee
25*2.05=51,25
Finally we can add it.
25.6+18+51.25=94,85$ - its the answer

Answer:

94.85

i hope this helps you !

Sue wants to know how many families in her small neighborhood of 50 homes would volunteer to help at a neighborhood animal shelter. She put all the addresses in a bag and drew a random sample of 25 addresses. She then asked those families if they would volunteer to help at the shelter. She found that 18% of the families would volunteer to help at the shelter. She claims that 18% of the neighborhood families would be expected to help at the animal shelter. Is this a valid inference?A Yes, this is a valid inference because the 25 families speak for the whole neighborhood

B Yes, this is a valid inference because she took a random sample of the neighborhood

C No, this is not a valid inference because she only asked 25 families

D No, this is not a valid inference because she did not take a random sample of the neighborhood

Answers

Answer

Yes, this is a valid inference because she took a random sample of the neighborhood.

Step-by-step explanation:

As we can see that Sue's survey was non biased and completely random.

She found that 18% of the families would volunteer to help at the shelter. She claims that 18% of the neighborhood families would be expected to to help at the animal shelter.

So, yes, this is a valid inference because she took a random sample of the neighborhood.

Answer:

the answer is B Yes, this is a valid inference because she took a random sample of the neighborhood.
