Answer:

8     9.8 - 6.4n

9      15 - j/2

Step-by-step explanation:

8

2.8 - 4.4n - 2n +7

= 2.8+7 -4.4n -2n

= 9.8 - 6.4n

9

11 + (-3) - 1/8 j - 3/8 j +7

= 11 - 3 - 1/8 j - 3/8 j + 7

= 11 - 3 + 7 - 1/8 j - 3/8 j

= 15 - 4/8 j

= 15 - j/2

The polynomial p(x)=1−2x2−3x3+4x has what order?<br><br> a. 4<br> b. 2<br> c. 3<br> d. 1
VLD [36.1K]

Answer:

3

Step-by-step explanation:

Given the polynomial : p(x)=1−2x2−3x3+4x

Rearranging : p(x) = -3x³ - 2x² + 4x + 1

Looking at the polynomial Given, we can see that it is a univariate polynomial, that is it has only one variable which is x. Thus for polynomials of this sort, the order of the polynomial is the highest exponent occurring in the polynomial equation. Therefore, the order of the polynomial above is 3, because the highest power of the function is 3.

This means that those with 4 as their highest exponent are of order 4 and those with highest exponent as 2 are of order 2.

Can you answer this question as soon as possible.
Whitepunk [10]

Answer:

The intensity of the first earthquake is 6.31 times the second one

Step-by-step explanation:

The given formulae is M=log(\frac{I}{S})

Here for both the earthquakes the value of S is same.

Let the Intensity of the first earthquake be I1 and the second be I2.

Given M1=7.5

M2=6.7

Now  M1=log(\frac{I1}{S})------1

M2=log(\frac{I2}{S})-----2

Now subtract 1 and 2 we get

M1-M2=log(\frac{I1}{I2})

I1/I2=10^{M1-M2}

I1=I2(10^{0.8}

I1=I2*6.31

Literal Equations: 8c + 6j = 5p, for c
bixtya [17]
8c + 6j = 5p         Subtract 6j from both sides
       8c = 5p - 6j   Divide both sides by 8
         c = \frac{5p - 6j}{8}

Which statement best describes how to determine whether f(x) = x3 + 5x + 1 is an even function?
kvasek [131]

Answer: Determine whether (–x)3 + 5(–x) + 1 is equivalent to x3 + 5x + 1.

To determine if a function is even, we need to check if f(-x)=f(x).
