Answer:

x = 37

Step-by-step explanation:

Vertically opposite angles are equal

Therefore,  2x + 6 = 80

Subtract 6 from both sides:   2x = 74

Divide both sides by 2:   x = 37

Find the volume of the solid that lies between planes perpendicular to the x-axis at x = pi/4 and x = 5pi/4. The cross-sections
svp [43]

Answer:

The volume of the solid = π²

Step-by-step explanation:

As per the given data of the questions,

The diameter of each disk is  

D = 2 sin(x) - 2 cos(x)

So its radius is

R = sin(x) - cos(x).

The area of each disk is

= \pi \times(sinx-cosx)^{2}

= \pi \times [sin^{2}(x) - 2 sin(x) cos(x) + cos^{2}(x)]

= \pi[1-2sin(x)cos(x)]

= \pi[1-sin(2x)]

Now,

Integrate from x=\frac{\pi}{4}\ \ \ to\ \ \ x=\frac{5\pi}{4}, we get volume:

V=\int_{\frac{\pi}{4}}^{\frac{5\pi}{4}} \pi[1-sin(2x)]dx

After integrate without limit we get

V=\pi[x+\frac{cos2x}{2}]

Now after putting the limit, we get

 V = π²

Hence, the required volume of the solid = π²

For the past 15 months, Frank recorded the cost of his monthly home heating bill and the corresponding average monthly temperatu
leonid [27]

The scatter plot shows that the heating bill will be about $95 for an average monthly temperature of 40°F.

<h3>What is a scatter plot?</h3>

It should be noted that a scatter plot uses dots to represent values for different numeric variables. In this case, the position of each dot on the horizontal and vertical axis shows the values for an individual data point.

From the complete question, the graph attached shows that the heating bill will be about $95 for an average monthly temperature of 40°F.

In conclusion, scatter plots are used to observe the relationships between variables.
