Which products result in a perfect square trinomial? Check all that apply.A=(–x + 9)(–x – 9)
B=(xy + x)(xy + x)
C=(2x – 3)(–3 + 2x)
D=(16 – x2)(x2 – 16)
E=(4y2 + 25)(25 + 4y2)

Answers

Answer 1

Answer:

The correct answers are:

B=(xy + x)(xy + x) ; C=(2x – 3)(–3 + 2x) ; and E=(4y² + 25)(25 + 4y²)

Explanation:

In order to have a perfect square trinomial, we must multiply two binomials that are exactly the same. For (xy+x)(xy+x), are multiplying two identical binomials.

For (2x-3)(-3+2x), we are multiplying two binomials that are the same but written in a different order. The same is true of (4y² + 25)(25 + 4y²).

Answer 2

Answer:

Answer:

A and E and C

Step-by-step explanation:

A perfect square trinomial can be written as the square of a binomial.

A project on Kickstarter.com was aiming to raise $15000 for a precision coffee press. They ended up with 714 supporters, raising 557% of their goal. How much did they raise?

Answers

The required solution is $83,550 raised.

It is required to find the amount did they raise.

What is percentage?

A part of a whole expressed in hundredths a high percentage of students attended. Also the result obtained by multiplying a number by a percent the percentage equals the rate times the base.

Given:

For a precision coffee press=$15000

Supporters=714

Raised= 557% of their goal.

According to given question we have,

They raise

15000 x 5.57

= $83,550 raised

Therefore, the required solution is $83,550 raised.

For this, we can set up a proportion.
Their aim was 15000, so if they raised 100% of their goal, they wouldve raised exactly 15000.
They raised 557%, so how much did they make?

Proportion:

$15000 100%
$x 557%

Our expression would be x=$15000*557% divided by 100%, which would be $83550, so... a lot of money.

(we did an “x” formation with the proportion, ie “connected” x with 100, and “connected” 15k and 557. The number connecting to x is what we divide the equation by, and the other two are multiplied and then divided by the first number connecting to x. Otherwise we couldve calculated 557% of 15000 and gotten the same result. Whichever way is easier for you :) )

Which is one of the transformations applied to the graph of f(x) = x2 to produce the graph of p(x) = –50 + 14x – x2? A.a shift down 1 unit
B.a shift left 7 units
C.a shift right 1 unit
D.a shift up 7 units

Answers

Answer: The correct option is (A) a shift down 1 unit.

Step-by-step explanation: The given functions are:

$f(x)=x^2,\n\np(x)=-50+14x-x^2.$

we are given to select the correct option which gives one of the transformations applied to the graph of f(x) to produce the graph of g(x).

We have

$p(x)=-50+14x-x^2\n\n\Rightarrow p(x)=-(x^2-14x+49)-1\n\n\Rightarrow p(x)=-(x-7)^2-1\n\n\Rightarrow p(x)+1=-(x-7)^2.$

Comparing the equation of p(x) with that of f(x), we conclude that the transformations are

(i) a horizontal shift of 7 units to the right,

(ii) a vertical shift of 1 unit downwards.

So, one of the correct transformations is - a shift down by 1 unit.

The graphs of f(x) and p(x) are attached below.

Thus, (A) is the correct option.

With regard to mathematics, what is an accepted statement of fact that is used to prove other statements?A)axiom
B)theroum
C)definition
D)undefined term

Answers

Answer – A. (Axiom)
With regard to mathematics, the accepted statement of fact that is used to prove other statements is an axiom. An axiom refers to any mathematical statement that functions as a starting point from which other mathematical statements are logically derived.

Answer:

With regard to mathematics, an axiom is an accepted statement of fact that is used to prove other statements.

Step-by-step explanation:

As we know that an axiom - normally called postulate - is a statement which is considered to be true in order to serve as an initial point in order to establish further reasoning, from which we may be able to logically drive the other mathematical statements.

Therefore, with regard to mathematics, an axiom is an accepted statement of fact that is used to prove other statements.

The graph of y=x^2 and y=cosx intercept in how many points?

Answers

They intercept in two points.

The graph y=x^2 is very basic so I suppose you know how it looks like.
It's like a U and starts from the origin (0,0)

The graph y=cosx is similar to y=x^2 but in a different way.
y=cosx doesn't pass from (0,0) it passes from (0,1) and then to (-1,0) and (1,0).
Basically, it goes like this..
~

If you know how the two graphs look like then you can understand why they intercept only two times.
