Answer:

a15 = 50

t25 = 33554427

Step-by-step explanation:

<em>Insert/Substitute the number given in for n.</em>

a15 = 3(15) + 5

a15 = 45 + 5

a15 = 50

~

t25 = 2^25 - 5     <em>2 times itself 25 times. 25 is the exponent in this equation</em>

t25 = 33554432 - 5

t25 = 33554427

Simplify:(-<br> 17)^8÷(-17)^2
lidiya [134]

The simplified answer is -17^6\\

If you are dividing powers with like terms you subtract the denominator to the numerator.

\frac{-17^8}{-17^2} = -17^6

Find the measures of two complementary angles if the difference in the measures of the two angles is 14
ira [324]
Complementary angles are angles that measure up to 90 degrees.

To find the measures of the two angles, divide 90 by two to say two angles of 45 degrees. Now divide 14 by 2, which you get 7 with. Now add 7 to 45 and subtract it from 45 as well, to get 52 and 38.

The measures of the angles are 52 degrees and 38 degrees.

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.
