Answer:

yes 0.265 is correct it is your answer

Answer:

Below in bold.

Step-by-step explanation:

(a) y=x^2sin2x

Using the Product Rule:

dy/dx = x^2*2cos2x + 2xsin2x

dy/dx = 2x(xcos2x + sin2x).

(b) y=ln sqrt(1+t^2)

     y = ln (1 + t^2)^1/2

Using the chain rule:

dy/dx =  1 / (1 + t^2)^1/2 * 1/2(1 + t^2)^-1/2 * 2t

=  2t/(1 + t^2)^1/2 * 1/ (2(1 + t^2)^1/2

=   2t / 2(1 + t^2)

= t / ( 1 + t^2).

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

[tex]y=\stackrel{\stackrel{m}{\downarrow }}{5}x+3\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

that means that the slope of line L is also 5, or 5/1 or   [tex]slope=\cfrac{\stackrel{rise}{5}}{\underset{run}{1}}[/tex]

Check the picture below.

Answer:

-5 and -5.

Step-by-step explanation:

Two negative numbers multiply to make a positive and add to make a negative.

Answer: Yes

Step-by-step explanation:

x=2 is a vertical line with an undefined slope, and y=5 is a horizontal line with a slope of 0. Since these lines have slopes that are negative reciprocals, they are perpendicular.

Step-by-step explanation:

Answer:

240°

Step-by-step explanation:

measure of XWZ = 360 - 120 = 240°

The measure of arc wz is 240 degrees.

here, we have,

we know that,

A small arc is one with a measure of fewer than 180 degrees. A major arc is one with a measure greater than 180 degrees. A semicircle is an arc that divides a circle in half and has a measure of 180 degrees.

An arc is a continuous segment of a circle. There are two sections, one of which is larger than the other. The major arc is the larger one, and the minor arc is the smaller one.

Given:

From diagram, m ∠xz = 120 degrees.

We know that whole circle = 360 degrees

So, measure of arc wz = 360 - 120

                                     = 240

Hence, the measure of arc wz is 240 degrees.

b. There are infinitely many solutions there are infinitely many numbers that are greater than or equal to 4

c. The boundary point for the inequality is at x=4 because any value less would make the inequality not true. The ralationship with the inequality is that it is the only solution that makes the inequality exactly equal to 13

d. (see image) just account for the x direction and ignore the y

Answer:

The car will be worth 6,624$ in 3-years

Step-by-step explanation:

Firstly we need to move the decimal two to the left, so the decimal form of 1% is 0.01.

Secondly, we make the equation by plugging in a multiplication sign and the cost of the car. Example - (0.01 x 10,350).

Now, that we have everything in an equation we can multiply 0.01 by 10,350, which will give us what 0.01 percent of 10,350 is, (103.5).

Lastly, we will subtract 103.5 from the cost of the car (10,350) to get the value of the car after the first month. The cost of the car will be $10,246.5. To find the value after the next two years we will repeat these steps...

weight = 30 kg

Force = weight × 10

= 30×10

= 300

Area = cm

= 100/100

Answer:

106.25 mph

Step-by-step explanation:

since the car travels at 85 miles per hour we divide it by 60 seconds in order to find how many miles is it to get in a minute

=> 85mph ÷ 60

divide 85 by 60

=> 1.416

multiply 1.416 by 15 to get how many miles it to go in 15 minutes

=> 21.25

then add it to 85

=> 106.25

Answer:

15: 10.99

2(3.14)r

3.5/2 = 1.75

2(3.14)1.75

2(3.14)8

50.24

17: 260%

2 = 200%

3/5 = 60%

200 + 60 = 260%

.5 is a decimal and you get it by dividing 1 by 2, or 1/2.

So 1/2 ultimately means .5.

Answer:

The conclusion

There is sufficient evidence to conclude that the  the residents of this particular city are spending significantly (at 5% level) more time watching TV than the average for this geographic area.

Step-by-step explanation:

From the question we are told that

   The population mean is [tex]\mu = 13 \ hours\ per\ week[/tex]

   The sample size is  n= 16

    The sample  mean is  [tex]\= x = 15.3[/tex]

    The standard deviation is  [tex]s = 3.8\ hours.[/tex]

   The null hypothesis is  [tex]H_o : \mu = 13[/tex]

    The alternative hypothesis is  [tex]H_a : \mu > 13[/tex]

     The level of significance is  [tex]\alpha = 0.05[/tex]

Generally the test statistics is mathematically represented as

      [tex]t = \frac{\= x - \mu }{ \frac{\sigma }{\sqrt{n} } }[/tex]

=>   [tex]t = \frac{15.3 - 13 }{ \frac{ 3.8 }{\sqrt{16} } }[/tex]

=>   [tex]t = 2.42[/tex]

 Generally the p-value is mathematically represented as

      [tex]p-value = P(z > 2.42)[/tex]

From the z -table  

       [tex]P(z > 2.42) = 0.0077603[/tex]

=>   [tex]p-value = 0.0077603[/tex]

From the values obtained we see that  [tex]p-value < \alpha[/tex]

Hence we reject the  null hypothesis

   Therefore there is sufficient evidence to conclude that the  the residents of this particular city are spending significantly (at 5% level) more time watching TV than the average for this geographic area.

Answer:

The range consisting of the p-value is, 0.000001 < p-value < 0.00001.

Step-by-step explanation:

The dependent t-test (also known as the paired t-test or paired samples t-test) compares the two means associated groups to conclude if there is a statistically significant difference amid these two means.

In this case a paired t-test is used to determine whether the percent population growth rate of major cities has decreased compared to the last decade.

The alternative hypothesis is Hₐ: [tex]\mu_{d}<0[/tex].

The test statistic value is, t = -5.053.

The degrees of freedom is, 16.

Compute the p-value as follows:

[tex]p-value=P(t_{16}<-5.053)=0.000059[/tex]

Thus, the range consisting of the p-value is, 0.000001 < p-value < 0.00001.
