Answer:

113.1

Step-by-step explanation:

Using the volume (for sphere) formula:

V = (4/3)*pi*(r^3)

You can plug in the radius (diameter/2, the diameter is 6m) to get a volume of 113.1.

Answer:

113.04m³

Step-by-step explanation:

[tex]Solution,\\\\Diameter(d)=6m\\\\Radius(r)=6m/2=3m\\\\Now,\\\\Volume=\frac{4}{3} \pi r^{3} \\\\Volume=\frac{4}{3} *3.14*(3m)^{3} \\\\Volume=113.04m^{3}[/tex]

Answer:

y = -2x - 3

Step-by-step explanation:

in the equation y = mx + b,

m = slope    b = y-intercept

The y-intercept is provided in the point, (0, -3), because that is where it crosses the y. You're y-intercept is -3

Now you need to find slope. You need to find the difference between these two points to find slope.

[tex]-2+0 = -2[/tex]

[tex]1-3=-2[/tex]

so your slope is going down by 2 and to the left by 2.

Hope this helps! Might be wrong. Try with another example and tell me if it works. <3

Answer: B

Step-by-step explanation:

m is the value of the slope between the two points on the graph

If the two coordinates is (x1,y1) and (x2,y2), the slope is (y1-y2) / (x1-x2)

So the slope for this question is (1-(-3)) / (-2-0) = -2 so the answer is B

Answer:

x <16/3

Step-by-step explanation:

7x - 4< 4(x+3)

Distribute

7x - 4< 4x+12

Subtract 4x from each side

7x-4x - 4< 4x-4x+12

3x-4 < 12

Add4 to each side

3x-4+4 < 12+4

3x<16

Divide each side by 3

3x/3 <16/3

x <16/3

Slope:-

[tex]\\ \rm\longmapsto m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \rm\longmapsto m=\dfrac{6-8}{-7-4}[/tex]

[tex]\\ \rm\longmapsto m=\dfrac{2}{11}[/tex]

Answer:

[tex]\frac{x-2}{3(x-3)}[/tex]

Step-by-step explanation:

The area of the shaded rectangle is [tex]A_1=\frac{x-2}{3}\times\frac{x+1}{4}[/tex]

The area of the large rectangle is [tex]A_2=\frac{x-3}{2}\times\frac{x+1}{2}=\frac{(x-3)(x+1)}{4}[/tex]

So the fraction is [tex]\frac{A_1}{A_2}=A_1\times\frac{1}{A_2}=\frac{x-2}{3}\times\frac{x+1}{4}\times\frac{4}{(x-3)(x+1)}=\frac{x-2}{3(x-3)}[/tex]

Step-by-step explanation:

Distribute the negative sign:

[tex]\frac{2}{7} x-3 -5/2-\frac{1}{5}y[/tex]

From the given, we can only find the difference with the integers.

Subtract the integers:

equation: [tex]y=0.05x+45.5[/tex]

graph: attached below

Step-by-step explanation:

We can write this in slope-intercept form, or [tex]y=mx+b[/tex]. Since x is defined as the #of text messages, and 0.05 is the cost of a text message, 0.05 will be m. 45.5 is the base price, or the y-intercept, so it will be b.

Plugging in these numbers, we get [tex]y-0.05x+45.5[/tex]

now we make y = 60, since that is the total amount they have

[tex]60=0.05x+45.5\\14.5=0.05x\\x=290[/tex]

So, they can send 290 messages for 60, but they need the bill under 60, so 1 text message less will be 289, and that's enough.

Using the slope concept, it is found that he stepped back 63.44 feet.

The slope is given by the vertical change divided by the horizontal change.

It's also the tangent of the angle of depression.

Initially, we have that:

Hence:

[tex]\tan{68^{\circ}} = \frac{85}{d}[/tex]

[tex]d = \frac{85}{\tan{68^{\circ}}}[/tex]

[tex]d = 34.34[/tex]

When he stepped back, the angle was of 41º, hence:

[tex]\tan{41^{\circ}} = \frac{85}{d}[/tex]

[tex]d = \frac{85}{\tan{41^{\circ}}}[/tex]

[tex]d = 97.78[/tex]

97.78 - 34.34 = 63.44.

Hence he stepped back 63.44 feet.

Divide the percent with the original price to get your answer

The time it will take the ball to reach a height of 90feet is 1.2 and 4.4secs

Given the height h (in feet) of the ball t seconds after being kicked expressed as:

h = –16t2 + 90t + 4.

If the ball is at a height of 90feet, hence:

90 = –16t2 + 90t + 4

–16t2 + 90t + 4 - 90 = 0

16t^2  -90t  + 86= 0

8t^2  -45t  + 43= 0

Factorizing the result to get the values of t:

[tex]t=\frac{45 \pm \sqrt{45^2-4(43)(8)} }{16} \\t=\frac{45 \pm \sqrt{2,025-1376} }{16} \\t=\frac{45 \pm {25.47}}{16} \\t=4.4s \ and\ 1.22secs[/tex]

Assuming that all other factors are equal, (and they never are), I would prefer a 20% or more ROI investment, located in a tax deferred, or tax exempt account!

Assuming that you are for some reason entirely unmotivated to look for better investments than the two you have pointed out, why not just buy the 8.1% investment with your IRA, Roth IRA, 401(k), SEP IRA, or spousal IRA funds?

You can then pretty much ignore your tax rate. Just move over any portion of your standard deduction that remains unused near the end of the year, via a Roth conversion. You will pay no additional taxes, and the money converted will forever remain free of RMDs, (which will otherwise occur later on), for the rest of your life!

Step-by-step explanation:

Use your now freed up taxable money to invest in tax free transactions, (similar to the effect of having a periodic Roth IRA), and live happily ever after!
