On dividing polynomial p(x) by a linear binomial, X - a, we get a quotien

Answer:

Step-by-step explanation:

Hello, we can write

(1) p(x)=(x-a)q(x)+r

\boxed{\sf v} True

It means that p(a)=0 * q(a) + r = r

so the first one is true.

\boxed{} False

The second one is not to be proven true from the remainder theorem.

\boxed{\sf v} True

For x different from a we can divide the equation (1) by (x-a).

\boxed{} False

We cannot say anything on q(a).

\boxed{\sf v} True

If the rest is 0 then it means that p(a) = 0

\boxed{\sf v} True

If p(a) = 0 it means that the rest r = 0 and then p(x)=q(x)(x-a)

Thank you

Answer:

The population mean is 5 volts

Step-by-step explanation:

Output voltage is assumed to be normally distributed, with standard deviation 0.25 Volts

s=0.25

n = 8

H_0:\mu = 5\\H_a:\mu \neq 5

Sample mean = \bar{x}=4.85

Since n < 30 and population standard deviation is unknown

So, we will use t test

Formula : t = \frac{x-\mu}{\frac{s}{\sqrt{n}}}

t = \frac{4.85-5}{\frac{0.25}{\sqrt{8}}}

t=-1.69

Refer the t table for p value

Degree of freedom = n-1 = 8-1 = 7

So,t_{(df,\alpha)}=t_{7,0.05}=2.365

P value >α

So, We are failed to reject null hypothesis

Hence The population mean is 5 volts

The graph shows the system y=2x+1 y=2x^2+1 Which ordered pairs are solutions of the system?
zhenek [66]
Hey!


To solve this problem, we would really have to graph both equations.

<em>OPEN THE FIRST IMAGE</em>

The first image I provided was the image of this equation graphed: <span>y=2x+1

<em>OPEN THE SECOND IMAGE</em>

The second image I provided was the image of this equation graphed: </span><span>y=2x^2+1


<em>PLEASE DO NOT LOOK AT THE THIRD IMAGE YET!</em>


The first image has two points. One at ( -0.5, 0 ) and the other at ( 0, 1 ).

The second image has only one point, which is at ( 0, 1 ).

<em>OPEN THE THIRD IMAGE</em>

Now, when both are combined we see that they intersect at two points, which are ( 0, 1 ) and ( 1, 3 ).

So, our answer is...

<em>The ordered pairs that are the solution to the system are</em>  </span><span>( 0,1 ) and ( 1,3 ).

Hope this helped!

Help help help! Lateral area means total surface area I believe!<br> Thanks!
pentagon [3]

\qquad\qquad\huge\underline{{\sf Answer}}☂

Let's solve ~

\qquad \sf  \dashrightarrow \:lateral \: surface \: area =  \pi rl

\qquad \sf  \dashrightarrow \:la = \pi12 \times 15

\qquad \sf  \dashrightarrow \:la =180 \pi

Therefore, the lateral surface area of cone = 180 pi in²
