Sweet and Sour: 8 quarts for $16 = 2 gallons for $16 = $8/gallon

Answer: Sweet and Sour has the higher unit price

2144 miles in 8 hours

2144/8 = 268 miles per hour

Answer a: 268

560 miles / 268 mph = 140/67 hours = 2.08955... hours

Answer: 2.09 hours

Enter the coefficients of the fifth Taylor polynomial T5(x) for the function f(x) = x5−3x4+2x2+5x−2 based at b=1. T5(x)= + (x−1)

DENIUS [597]

Compute the necessary values/derivatives of $f(x)$ at $x=1$ :

$f(1)=3$

$f'(1)=2$

$f''(1)=-12$

$f'''(1)=-12$

$f^{(4)}(1)=48$

$f^{(5)}(1)=120$

Taylor's theorem then says we can "approximate" (in quotes because the Taylor polynomial for a polynomial is another, exact polynomial) $f(x)$ at $x=1$ by

$T_5(x)=\dfrac3{0!}+\dfrac2{1!}(x-1)-\dfrac{12}{2!}(x-1)^2-\dfrac{12}{3!}(x-1)^3+\dfrac{48}{4!}(x-1)^4+\dfrac{120}{5!}(x-1)^5$

$T_5(x)=3+2(x-1)-6(x-1)^2-2(x-1)^3+2(x-1)^4+(x-1)^5$

###

Another way of doing this would be to solve for the coefficients $a,b,c,d,e,g$ in

$f(x)=a+b(x-1)+c(x-1)^2+d(x-1)^3+e(x-1)^4+g(x-1)^5$

by expanding the right hand side and matching up terms with the same power of $x$ .

Are there any supplementary, vertical, or complimentary angles? If so wich ones

FromTheMoon [43]

Supplementary: N and M

Supplementary angles: A pair of angles whose sum is equal to 180°.

Vertical: N and R

Vertical angles: A pair of opposite angles that are made by two intersecting lines.

Complimentary: P and Q

Complimentary angles: A pair of angles whose sum is equal to 90°.

Hope this helps! :D

In a poll, 312 of 1040 randomly selected adults aged 18 or older stated that they believe there is too little spending on natio

jonny [76]

Answer: A point estimate for the proportion of adults aged 18 or older who feel there is too little spending on national defense is 0.3.

Step-by-step explanation:

Given : In a poll , the sample size of adults aged 18 or older : n=1040

Out of them , the number of persons stated that they believe there is too little spending on national defense: x= 18

Let p be the proportion of adults aged 18 or older who feel there is too little spending on national defense.

Now , as per sample , the sample proportion of adults aged 18 or older who feel there is too little spending on national defense would be :

$\hat{p}=\dfrac{x}{n}=\dfrac{312}{1040}=0.3$

Since , the sample proportion is the best estimate of the population proportion.

Therefore, a point estimate for the proportion of adults aged 18 or older who feel there is too little spending on national defense is 0.3.
