Does anyone know this??

1 answer:

The answer is D, because it is all of the y values. It only has 2 in there once because since it repeats, it doesn't need to be put in twice.

Calculate the l4 approximation for f(x) = cos2(x) on 8 , 2 . (round your answer to four decimal places.) l4 =

BaLLatris [955]

The solution for l4 is mathematically given as

L_{4}=0.5431

<h3>What is the solution for l4?</h3>

$&\text { Given } f(x)=a \cos ^{2}(x) \quad\left[\frac{\pi}{8}, \frac{\pi}{2}\right] \text { \& } n=4\\\\&\Delta a=\frac{b-a}{n}=\frac{\pi / 2-\pi / 8}{9}=\frac{3 \pi}{32}\\\\&x_{0}=\pi / 8, x_{1}=\frac{\pi}{8}+\frac{3 \pi}{32}=\frac{7 \pi}{32}\\\\&x_{2}=\frac{5 \pi}{16}, \quad x_{3}=\frac{13 \pi}{32}, x_{4}=\pi / 2\\\\&f\left(x_{0}\right)=f(1 / 8)=0.8535\\$

$&f\left(x_{1}\right)=f\left(\frac{7 \pi}{32}\right)=0.5975\\\\\&f\left(x_{2}\right)=f\left(\frac{5 \pi}{16}\right)=0.3086\\\\\&f\left(a_{3}\right)=f\left(\frac{13 \pi}{32}\right)=0.0842\\\\\&L_{4}=\sum_{k_{0}^{=0}}^{3} f\left(x_{k}\right) \Delta x\\\\&=\Delta \\\\x\left[f\left(x_{0}\right)+f\left(x_{1}\right)+f\left(x_{2}\right)+f\left(x_{3}\right)\right]\\\\\&=\frac{3 \pi}{32}[0.8535+0.5975+0.3056+0.0842]\\\\&L_{4}=0.5431$

Find the taxable income of a married couple with three children, who have a combined income of $62,000.

xeze [42]

Answer :

taxable income is $30,300

Step-by-step explanation:

Given

The combine income of the husband and wife = $62,000

Number of children the couple has = 3

In order to find out the taxable income for an U.S. family, the following formula is used

taxable income = total income - exemption deduction - standard deduction

We know the exemption deduction for a married couple with three kids fixed according to the U.S. government is $19,500.

And the standard deduction for a married couple with three kids fixed according to the U.S. government is $12,200.

Therefore,

taxable income = total income - exemption deduction - standard deduction

= $62,000 - $19,500 - $12,200

= $30,300

Thus the taxable income is $30,300.

What's the answer? please help

V125BC [204]

Answer:

C. 35

Step-by-step explanation:

I just went through all the numbers, multiplied them by 2, because you start with x which is 50, and the goal is to get to 120 with 50 and a number multiplied by two, so I tried 35 which would be 70 when multiplied by two, then added 50, which would make 120.
