          [tex]\boxed{-w^3 + 4w^2 + -8w + 7}[/tex]

Let's simplify step-by-step.

[tex](-w^3+8w^2-3w)-(4w^2+5w-7)[/tex]

Distribute the Negative Sign:

[tex]= -w^3 + 8w^2 - 3w + -1( 4w^2 + 5w - 7 ) \\= - w^3 + 8w^2 + 3w + -1(4w^2) + -1 (5w)+(-1 )(-7)\\= -w^3 + 8w^2 + -3w + -4w^2 + 5w + 7[/tex]

Combine Like Terms:

[tex]= -w^3 + 8w^2 + -3w + -4w^2 + -5w + 7 \\= (-w^3) + ( 8w^3 + -3w + -4w^2) + ( -3w + -5w) + 7 \\= -w^3 + 4w^2 + -8w + 7[/tex]

Answer:

2x² - 19x + 42

Step-by-step explanation:

We want to expand (x - 6)(2x - 7) into a trinomial.

We use the FOIL (first, outer, inner, last) method.

First, multiply the first terms of each parenthetical expression; in the first one, that's x, and in the second, that's 2x:

x * 2x = 2x²

Next, multiply the outer terms; in the first one, that's x, and in the second, that's -7:

x * (-7) = -7x

After that, multiply the inner terms; in the first one, that's -6 and in the second, that's 2x:

(-6) * 2x = -12x

Finally, multiply the last terms; in the first one, that's -6 and in the second, that's -7:

(-6) * (-7) = 42

Now, add all these results together:

2x² + (-7x) + (-12x) + 42

2x² - 19x + 42

The answer is thus 2x² - 19x + 42.

Answer:

399.17 miles

Step-by-step explanation:

Gunnar's car gets 22.4 miles per gallon. His gas tank can hold 17.82 gallons of gas.

Gunnar's car travels with one gallon of gas = 22.4 miles

He can travel with 17.82 gallon of gas = 17.82 × 22.4

                                                             = 399.168 ≈ 399.17 miles

Gunnar can travel 399.17 miles if he uses all of the gas in the gas tank.

Answer:

the LCM would be 8 based on the following set of multiples: Multiples of 2: 2, 4, 6, 8, 10, 12, 14, ... Multiples of 8: 8, 16, 24, 32, 40, 48, 56, ...

Step-by-step explanation:

Answer:

The first three nonzero terms in the Maclaurin series is

[tex]\mathbf{ 5e^{-x^2} cos (4x) }= \mathbf{ 5 ( 1 -9x^2 + \dfrac{115}{6}x^4+ ...) }[/tex]

Step-by-step explanation:

GIven that:

[tex]f(x) = 5e^{-x^2} cos (4x)[/tex]

The Maclaurin series of cos x can be expressed as :

[tex]\mathtt{cos \ x = \sum \limits ^{\infty}_{n =0} (-1)^n \dfrac{x^{2n}}{2!} = 1 - \dfrac{x^2}{2!}+\dfrac{x^4}{4!}-\dfrac{x^6}{6!}+... \ \ \ (1)}[/tex]

[tex]\mathtt{e^{-2^x} = \sum \limits^{\infty}_{n=0} \ \dfrac{(-x^2)^n}{n!} = \sum \limits ^{\infty}_{n=0} (-1)^n \ \dfrac{x^{2n} }{x!} = 1 -x^2+ \dfrac{x^4}{2!} -\dfrac{x^6}{3!}+... \ \ \ (2)}[/tex]

From equation(1), substituting x with (4x), Then:

[tex]\mathtt{cos (4x) = 1 - \dfrac{(4x)^2}{2!}+ \dfrac{(4x)^4}{4!}- \dfrac{(4x)^6}{6!}+...}[/tex]

The first three terms of cos (4x) is:

[tex]\mathtt{cos (4x) = 1 - \dfrac{(4x)^2}{2!}+ \dfrac{(4x)^4}{4!}-...}[/tex]

[tex]\mathtt{cos (4x) = 1 - \dfrac{16x^2}{2}+ \dfrac{256x^4}{24}-...}[/tex]

[tex]\mathtt{cos (4x) = 1 - 8x^2+ \dfrac{32x^4}{3}-... \ \ \ (3)}[/tex]

Multiplying equation (2) with (3); we have :

[tex]\mathtt{ e^{-x^2} cos (4x) = ( 1- x^2 + \dfrac{x^4}{2!} ) \times ( 1 - 8x^2 + \dfrac{32 \ x^4}{3} ) }[/tex]

[tex]\mathtt{ e^{-x^2} cos (4x) = ( 1+ (-8-1)x^2 + (\dfrac{32}{3} + \dfrac{1}{2}+8)x^4 + ...) }[/tex]

[tex]\mathtt{ e^{-x^2} cos (4x) = ( 1 -9x^2 + (\dfrac{64+3+48}{6})x^4+ ...) }[/tex]

[tex]\mathtt{ e^{-x^2} cos (4x) = ( 1 -9x^2 + \dfrac{115}{6}x^4+ ...) }[/tex]

Finally , multiplying 5 with [tex]\mathtt{ e^{-x^2} cos (4x) }[/tex] ; we have:

The first three nonzero terms in the Maclaurin series is

[tex]\mathbf{ 5e^{-x^2} cos (4x) }= \mathbf{ 5 ( 1 -9x^2 + \dfrac{115}{6}x^4+ ...) }[/tex]

Step-by-step explanation:

Hello, we assume that x is different from 0 and f different from 2b

[tex]b+\dfrac{3}{x}=\dfrac{f}{2}\\\\\text{Subtract b}\\\\+\dfrac{3}{x}=\dfrac{f}{2}-b\\\\\text{Mulitply by 2x}\\\\+\dfrac{3*2*x}{x}=6=\dfrac{2xf}{2}-2bx=(f-2b)x\\\\\text{Divide by f-2b}\\\\\Large \boxed{\sf \bf x=\dfrac{6}{f-2b}}[/tex]

Answer:

(-1, -1)

Step-by-step explanation:

To find where two lines in slope-intercept form intersect, set them equal to each other.

2x + 1 = -5x - 6

7x = -7

x = -1

Knowing they intersect at x = -1, substitute -1 into either of the two equations to find the y-value of their intersection.

y = 2(-1) + 1

y = -2 + 1

y = -1

So the intersection point of the two lines is (-1, -1).

Answer:

6.6×10²¹

Step-by-step explanation:

6,600,000,000,000,000,000,000 → there are 21 place values after the first non-zero number ''6''

to convert to standard form, we move the decimal point after the first non-zero number.  

6,600,000,000,000,000,000,000.0 ← decimal in the end

the decimal will be moved, all the digits after the decimal are counted and they will resemble the index.

Answer:

346.78

Step-by-step explanation:

Rounding a number to hundredth means approximating or making the number after the second position of the decimal to either a 10 or zero.

Thanks for the number after the second is greater or equal to 5, it is rounded up to ten where the 1 is added to the second position if not it turns 0.

So 346.7812 to hundredth

= 346.78

Answer: 6062

Add Parentheses

[tex](6.2*10)+(6*10^3)[/tex]

Note: Always Multiply the Parentheses first!

Multiply

[tex]6.2*10=62[/tex]

[tex]6*10^3=6000[/tex]

How is 6×10^3 6000?

Before you multiply the whole equation you first Multiply 10 3 times. This is called an Exponent. In my own words, an exponent is a number that tells you how many times to multiply that number. So if we had 6^2 I will multiply 6×6 2 times. So we multiply 10×10×10 and get 1000. Then we multiply 6×1000 and get 6000.

Add

Since the final step is to add we Add the answer we got for 6.2×10 and 6×10^3.

Therefore we are adding 62*6000 and we get 6062.

Step-by-step explanation:

Given number is x, then:

The number is 30

Answer:

0.48 rad/sec

Step-by-step explanation:

From the diagram:

We can find 'x' using trigonometry :

Tanθ = opposite / Adjacent

Opposite = x ; adjacent = 4

Tanθ = x / 4

x = 4tanθ

Let u = 4 and v = tanθ

If dx/dt = 3ft/s ;

dθ/dt when x = 3ft

Differentiate x with respect to t

dx/dt (4tanθ)

Let d/dθ tanθ = sec^2θ

Sec^2θ = 1 / cos^2θ

dθ/dt = 1/4cos^2θdx/dt

dθ/dt = 1/4cos^2θ(3)

dθ/dt = 3/4cos^2θ

When x = 3ft

Cosθ = Adjacent / Hypotenus

Hypotenus = √(4^2 + 3^2

Hypotenuse = √16 + 9 = √25 = 5

Cosθ = 4/5

dθ/dt = 3/4(4/5)^2

dθ/dt = 3/4(16/25)

dθ/dt = 48/100 = 12/25 = 0.48 rad/sec

Complete Question

The  complete question is shown on the first uploaded image  

Answer:

The interval is  [tex]-0.0037 < p_1-p_2<-0.0023[/tex]

Step-by-step explanation:

From the question we are told that

   The first  sample size is  [tex]n _1 = 1068000[/tex]

    The  first sample proportion is [tex]\r p_1 = 0.089[/tex]

    The  second sample  size is  [tex]n_2 = 1476000[/tex]

    The  second sample proportion is  [tex]\r p_2 = 0.092[/tex]

Given that the confidence level is  95% then the level of significance is mathematically evaluated as

             [tex]\alpha = (100 - 95 )\%[/tex]

              [tex]\alpha = 0.05[/tex]

Next we obtain the critical value  of  [tex]\frac{\alpha }{2}[/tex]  from the normal distribution table  

The value is  

               [tex]Z_{\frac{\alpha }{2} } =z_c= 1.96[/tex]

Generally the 95% confidence interval is mathematically represented as

       [tex](\r p_1 - \r p_2 ) -z_c \sqrt{ \frac{\r p_1 \r q_1 }{n_1} + \frac{\r p_2 \r q_2 }{n_2}} < (p_1 - p_2 ) < (\r p_1 - \r p_2 ) +z_c \sqrt{ \frac{\r p_1 \r q_1 }{n_1} + \frac{\r p_2 \r q_2 }{n_2}}[/tex]

Here  [tex]\r q_1[/tex] is mathematically evaluated as [tex]\r q_1 = (1 - \r p_1)= 1-0.089 =0.911[/tex]

and  [tex]\r q_2[/tex]  is mathematically evaluated as  [tex]\r q_2 = (1 - \r p_2) = 1- 0.092 = 0.908[/tex]

So

       [tex](0.089 - 0.092 ) -1.96 \sqrt{ \frac{0.089* 0.911 }{1068000} + \frac{0.092* 0.908 }{1476000}} < (p_1 - p_2 ) < (0.089 - 0.092 ) +1.96 \sqrt{ \frac{0.089* 0.911 }{1068000} + \frac{0.092* 0.908 }{1476000}}[/tex]

[tex]-0.0037 < p_1-p_2<-0.0023[/tex]
