I don’t understand the question ! Plz help me !

Sauron [17]

Answer:

Step-by-step explanation:

I'm not sure but there is a rule that the sum of out side angles of each shape is 360

saying that 360/5= 72

so if we continue the lines it will be 36 degree to of the outside angles and 18 degree each

Not let's make that into another rectangle (The one that is upside down)

180- (2*18)= 144

So the big degree is 144

now again

(180-144)/2=18

So each of those small red angles are 18

Which function is a quadratic function? y – 3x2 = 3(x2 + 5) + 1 y2 – 7x = 2(x2 + 6) + 7 y – 2x2 = 6(x3 + 5) – 4 y – 5x = 4(x + 5

Anna71 [15]

Answer:

Option A.

Step-by-step explanation:

The general form of a quadratic function is

$y=ax^2+bx+c$

It means, power of y should be 1 and highest power of x should be 2.

In option A,

$y-3x^2=3(x^2+5)+1$

$y-3x^2=3x^2+15+1$

$y=3x^2+16+3x^2$

$y=6x^2+16$

It is a quadratic function.

In option B,

$y^2-7x=2(x^2+6)+7$

Here, power of y is 2. So, it is not be a quadratic function.

In option C,

$y-2x^2=6(x^3+5)$

Here, highest power of x is 3. So, it is not be a quadratic function.

In option D,

$y-5x=4(x+5)+9$

Here, highest power of x is 1. So, it is not be a quadratic function.

Therefore, the correct option is A.

Answer:

(a)

degree is 4

it is binomial

(b)

degree is 2

it is trinomial

(c)

degree is 3

it is monomial

Step-by-step explanation:

(a)

we are given function as

$f(x)=5x^4-8$

Degree:

we know that degree is highest exponent value

so, degree is 4

Number of terms:

we can see that there are two terms

so, it is binomial

(b)

we are given function as

$f(a)=4a^2-2a-16$

Degree:

we know that degree is highest exponent value

so, degree is 2

Number of terms:

we can see that there are three terms

so, it is trinomial

(c)

we are given function as

$f(m)=9m^3$

Degree:

we know that degree is highest exponent value

so, degree is 3

Number of terms:

we can see that there are one term

so, it is monomial
