What are the key aspects of the graph of f(x) = x2 – b2, where b is a real number?
netineya [11]

Given equation is f\left(x\right)=x^2-b^2.

Now we need to find about what are the key aspects of the graph of f\left(x\right)=x^2-b^2, where b is a real number.

We know that square of any number is always positive.

then b^2 must be a positive number.

So that means for any real number b, as the value of b increases then graph of f(x) shifts downward by b^2 units as compared to the graph of parent function f\left(x\right)=x^2

On the 7th, Andi had $48 in her account. We want to find when she had $92 less than what she had on the 7th.

First, let's find out how much $92 less is:

We are looking for when Andi had $-44 in her account. Looking at the number line, the day Andi had $-44 in her account was on the 14th.

The correct answer is C. The 14th.

At an opening of a new art gallery the owner hired a caterer to serve light snacks. The owner created a budget for 150 people to
Vsevolod [243]

Answer: $357 is more amount budgeted for food increase.

Explanation:

Since we have given that

Number of people according to the budget = 150

Cost of food per person= $4.25

Total cost of food is given by

150\times 4.25=\$637.5

If the number of guests attending the opening was 56% more than expected,

So, number of guests now is given by

150\times 0.56=84\\\\150+84=234

Total cost of food is given by

234\times 4.25=\$994.5

Difference between them is given by

994.5-637.5=\$357

Hence, $357 is more amount budgeted for food increase.

How many places do you need to move the decimal to the left to write the number below in scientific notation?
bonufazy [111]

Answer:

A) 1.3*10¹

B)7*10⁰ - Actually I am not very sure if it is required to write 10⁰. I normally don't write 10⁰ (When I solve problems in physics if the answer for example is 7 I just write 7 not 7*10⁰). But if you check on Google 10⁰ has been mentioned

C)1.4*10¹

D)1.2*10¹

Step-by-step explanation:

For any number when you express it in a scientific notation, You should make sure that the number (for example : X) X which is going to be multiplied with a power of 10 (for example:10³,10⁴10¹⁰ etc), X should be between 1 and 10

This might sound very complicated so I can give you an example to simplify

Let's take 1.3*10¹

In this case X is 1.3

This means X*10¹

The number X is being multiplied with the power of 10(example:10¹,10²,10⁰,10⁹ ,etc) .In the above case X is being multiplied with 10¹.

Now this number X should be between 1 and 10.(Including 1)

Scientific notation= X*power of 10

where x>=1 & x<10

That is the explanation

Hope it helps

If you think my explanation is a bit complicated

you can ask me again

Find the value of t perimeter
Natali5045456 [20]

Answer:

<h2><em><u>t = 15.2 is the answer</u></em></h2>

Step-by-step explanation:

<h2><em><u>1. Make an equation</u></em></h2>

numbers to find perimeter = perimeter

Side + Side + 2 unknown sides = perimeter

12 + 7.8 + 2t = 50.2

<h2><em><u>2. Simplify like terms</u></em></h2>

19.8 + 2t = 50.2

<h2><em><u>3. Solve</u></em></h2>

19.8 + 2t = 50.2

-19.8        - 19.8

2t = 30.4

<h2><em><u>t = 15.2</u></em></h2>

<h2><u><em>4. Check:</em></u></h2>

12 + 7.8 + t + t = 50.2

12 + 7.8 + (15.2) + (15.2) = 50.2

<h2><em><u>50.2 = 50.2</u></em>   Correct!</h2><h2 />

Hope this helped,
