Answer:

5.5

Step-by-step explanation:

The volume of a sphere is represented by the formula 4/3πr^3. So, if we set 4/3πr^3 equal to 2048/3, we can start solving. Start by multiplying both sides by 3/4, the reciprocal of 4/3 to get rid of the fraction. This gives us πr^3 = 512. Divide 512 by π to get 163.1 (when rounded to the nearest tenth). This leaves us with r^3 = 163.1; find the cubic root of 163.1, which is 5.5, to get r

Given A(8,3), B(4,8), C(4,4) and D(8,-1) find the slope of AB

Snezhnost [94]

Answer:

Step-by-step explanation:

Slope: $\frac{y_2-y_1}{x_2-x_1}$ when the given points are $(x_1,y_1)$ and $(x_2,y_2)$

Plug in A(8,3) and B(4,8)

$=\frac{8-3}{4-8} \\=\frac{5}{-4}\\=-\frac{5}{4}$

Therefore, the slope of AB is $-\frac{5}{4}$ .

I hope this helps!

The lengths of two sides of a triangle are shown below:

Feliz [49]

Answer:

Part A) $(3x^2 - 6x - 10) + (5x^2 + 9x - 8 ) =8x^2 + 3x - 18$

Part B) $(10x^2 - x - 3) - (8x^2+3x-18) = 2x^2 -4x+15$

The wind speed s (in miles per hour) is related to the distance (in miles) the tornado travels by the equation s = 93log d + 65.

Vesnalui [34]

Answer:

The distance the tornado traveled was approximately 205 miles.

Step-by-step explanation:

The equation representing the relationship between the wind speed (in miles per hour) and the distance the tornado travels (in miles) is:

$s=93\log d+65$

Compute the value of <em>d</em> for <em>s</em> = 280 as follows:

$s=93\log d+65$

$280=93\log d+65$

$93\log d=280-65\\93\log d=215$

$\log d=2.312\\$

$d=10^{2.312}\\d=205.035\\d\approx 205$

Thus, the distance the tornado traveled was approximately 205 miles.
