Answer: What is a factor?

A factor is a a divisor of an integer n, also called a factor of n, is an integer m that may be multiplied by some integer to produce n. In this case, one also says that n is a multiple of m. An integer n is divisible by another integer m if m is a divisor of n; this implies dividing n by m leaves no remainder.

Step-by-step explanation: Why can’t certain expressions be factored?

Because there are no common factors other than 1 the constants cannot be factored. And, because there is no x in the second term (10), we cannot factor an x out of the two terms.

Estimate the minimum number of subintervals to approximate the value of Integral from negative 3 to 3 (2 x squared plus 9 )dx wi

vichka [17]

Answer:

The value of n for (a) n=425. (b) n=0.

Step-by-step explanation:

Given integration is,

$\int_{-3}^{3}f(x)=\int_{-3}^{3}(2x^2+9)dx$

(a) For Trapezoidal Rule : Composite error is,

$E_T=-\frac{(b-a)^3}{12n^2}f''(x_m)$

Where, f''(x_m)=greatest value of |f''(x)|= |4|=4, a=-3, b=3. Therefore to find the minimum number of subinterval,

$|E_T|\leq | \frac{(b-a)^3}{12n^2}f''(x)|$ |

$\leq \frac{4(-3-3)^3}{12n^2}$

$=\frac{72}{n^2}$

According to the question, we must choose n such that,

$\frac{72}{n^2}$

$\implies n>424.2640686$

So we can take n=425.

(b) For Simpson 1/3 rule : Composite error is,

$E_S=-\frac{(b-a)^5}{180n^4}f^{(iv)}(x_m)$

where, $f^{(x_m)}=\textit{greatest value of} |f^{(iv)}(x)|$

In this problem $f^{(iv)}(x)=0$ , so that,

$|E_S|\leq 0$

that is there exist no error. So n=0.

Sarah has 12 bags of apples. Mikaela has 17 bags of apples. Each bag has the same amount of apples inside. Wrie an expression fo

hodyreva [135]

The expression for the total amount of apples is 29x

Solution:

Given that,

Sarah has 12 bags of apples

Mikaela has 17 bags of apples

Each bag has the same amount of apples inside

Let "x" be the number of apples in each bag

Then,

Sarah has 12x apples

Mikaela has 17x apples

Wrie an expression for the total amount of apples

Total amount of apples = 12x + 17x

Then simplify it using the distributive property to create an equivalent expression

By distributive property,

a(b + c) = ab + bc

Therefore,

$12x+17x = x(12+17)\\\\12x+17x = 29x$

Thus expression for the total amount of apples is 29x

1. perimeter 10(2)+10(2)=32+20

perimeter = 52cm

area=b times h

area = 16(9)=144cm2

2 TRAPEZOID

perimeter =( 21+24+25+44.67)m

=114.67m

area= 1/2( b1+b2)h

1/2(44.67+25)20

696.7m2

3. perimeter = 2+3+12+2+3+5+3+2+9+7+3

=51cm

area = 54+6+6+6=72cm2

4. perimeter is 10+4+2+3+ 2+4+10+23 = 58cm

area is 

(11+23).8=37.8
