kvv77 [185]3 years ago

5 0

Answer:

It would be all of the above.

Step-by-step explanation:

An example of a polynomial is:

2x^3 - 4x^2 +1x -8

Note how there are exponents, such as ^3 for example. There is also a variable, in this case x. Lastly, there are constants, which are numbers by themselves.

Answer:

<h2> $- {x}^{4} - 7 {x}^{3} + 8$ </h2>

Step-by-step explanation:

$(5 - 5 {x}^{4} - {x}^{3} ) - (6 {x}^{3} - 4 {x}^{4} - 3)$

Remove unnecessary parentheses

$5 - 5 {x}^{4} - {x}^{3} - (6 {x}^{3} - 4 {x}^{4} - 3)$

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression

$5 - 5 {x}^{4} - {x}^{3} - 6 {x}^{3} + 4 {x}^{4} + 3$

Collect like terms

$5 + 3 - 5 {x}^{4} + 4 {x}^{4} - {x}^{3} - 6 {x}^{3}$

$5 + 3 - {x}^{4} - 7 {x}^{3}$

Add the numbers

$8 - {x}^{4} - 7 {x}^{3}$

Use the commutative property to reorder the terms

$- {x}^{4} - 7 {x}^{3} + 8$

Hope this helps...

Best regards!!

Recall the equation for a circle with center ( h , k ) and radius r . At what point in the first quadrant does the line with equ

astraxan [27]

Answer:

The Point in the first quadrant is $(\sqrt[2]{2.0268} ,6.559)$ .

Step-by-step explanation:

Since

we know the general equation of the circle whose center is at (h,k) and radius is r that is

$(x-h)^2+(y-k)^2 =r^2$

we have given center is (0,3) and radius is r= 4

substituting in the general equation of the circle we get

$x^2 +(y-3)^2 = 16$

Now substituting the y= 2.5x + 3 in the above equation we get

$x^2 +(2.5x + 3-3)^2 = 4^2$

$x^2 +6.25x^2 = 16$

here subtracting 16 from both sides and also perform addition

we get

$7.25x^2 = 16$

dividing both sides by 7.25 we get

$x^2 =2.2068$

taking square root both sides we get

$x= \frac{+}{-}\sqrt[2]{2.0268}$

but we need positive value of x because both x and y are positive in the first quadrant

that is

$x= \sqrt[2]{2.0268}$

substituting this into the given equation of the line we get

y = 2.5( $\sqrt[2]{2.0268}$ )+3

y = 6.559

so the point in the first quadrant is ( $\sqrt[2]{2.0268}$ ,6.559)

that is required
