Write the polynomial in standard form. Then name the polynomial based on it's degree and number of terms.
Ivenika [448]

ANSWER

c. 6x^2 + 2x + 8, quadratic trinomial

EXPLANATION

The given polynomial is

8 - 4 {x}^{2}  + 10 {x}^{2}  + 2x

We regroup the terms to get;

10  {x}^{2}  - 4 {x}^{2}  + 2x + 8

Simplify now to obtain:

6 {x}^{2}  + 2x + 8

This is a quadratic polynomial function based on the degree.

It is also a trinomial based on the number of terms.

The correct answer is C

If (−4, 11) and (−6, 5) are the endpoints of a diameter of a circle, what is the equation of the circle?
lora16 [44]

Answer:

A. (x+5)^2+(y-8)^2=100

Step-by-step explanation:

1. The standard form of the equation of a circle is (x-h)^{2} + (y-k)^2=r^2

2. To find the center we require the  midpoint   of the  2 given points

center =[\frac{1}{2}(-4-6),\frac{1}{2}(11+5)]

=(-5,8)

3. The radius is the distance from the centre to either of  the 2 given points calculate the radius using the  distance formula

d= \sqrt{(x_{2}+x_{1})^{2} +(y_{2}-y_{1})^{2}

let (x_{1},y_{1})= (-5,8) \\ and (x_2,y_2)=(-4,11)

r=\sqrt{(-4+5)^2+(11-8)^2} =\sqrt{81+9}=10

--> (x-(-5)^2+(y-8)^2=10^2

--> (x+5)^2+(y-8)^2=100

For a science report, Doug is measuring widths of mushrooms with a ruler that divides inches as shown. To determine each width,
Serga [27]
From the 3 options listed, both 5.25 in and 6.5 in could be measures found using a ruler with eighth inches marked, because those decimals can be written in terms of eighth fractions.

5.25 $in $ \rightarrow (5 + 0.25) $in $ \rightarrow (5 +  \frac{2}{8} ) $in$ \\ 
6.5 $in $ \rightarrow (6 + 0.5) $in $ \rightarrow (5 +  \frac{4}{8} ) $in$

The other option, 7.1 in, is not a possibility because 0.1 cannot be written as a fraction of 8 that is marked on the ruler.

Help me !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ElenaW [278]
So 20% is 1/5 as a percent.

So 1/5 multiplied by 5 equals 5/5, or 1.

So if 1/5 = 6, then 6 multiplied by 5, or 30, must equal 5/5, or 1.

So the total number of dolls in Amyia's doll collection is 30.
