harina [27]

Answer:

n < 27

Step-by-step explanation:

let the number be n

\frac{1}{3} n - 3 < 6 \\ add \: 3 \: to \: both \: sides \\  \frac{1}{3}n - 3 + 3  <  6 + 3 \\  \frac{1}{3} n  <  \\  9 \\ multiply \: both \: sides \: by \: 3 \\  \frac{1}{3} n  \times 3< 9 \times 3 \\ n < 27

1. Use the given Taylor polynomial p 2 to approximate the given quantity.
KiRa [710]

Answer:

Part 1:

P₂(0.07)=0.93245≈e^{-0.07}

Part 2:

Error=0.5618*10^{-4}

Step-by-step explanation:

Given:

f(x)=e^{x}\\f(-0.07)=e^{-0.07}

P₂(x)=1-x+\frac{x^2}{2}

Solution:

Part 1:

P₂(x)=1-x+\frac{x^2}{2}

We have x=0.07

Put Value of x in above Equation:

P₂(0.07)=1-0.07+\frac{0.07^2}{2}

P₂(0.07)=0.93245≈e^{-0.07}

Part 2:

e^{-0.07}=0.93239382 (Calculated using Calculator)

Error=|e^{-0.07}-P₂(0.07)|=|0.93239382-0.93245|=0.00005618

Error=|0.93239382-0.93245|

Error=0.00005618

Error=0.5618*10^{-4}

8 Mike jogged 6 laps around a 0.25-mile track on
Radda [10]

Answer:

1.5 + 1.75 = 3.25 miles jogged on Monday and Tuesday combined.

Step-by-step explanation:

The number of miles he jogged on both days combined is just the sum of the miles of laps he jogged on both days.

Since he jogged 6 laps around a 0.25 mile track on Monday, this means he jogged 6(0.25) = 1.5 miles on Monday.

Since he jogged 7 laps around the same 0.25 mile track on Tuesday, he jogged 7(0.25) = 1.75 miles on Tuesday.

Summing them up, 1.5 + 1.75 = 3.25 miles jogged on Monday and Tuesday combined.
