For this case we have, that by definition, the volume of a cone is given by:

$V = \frac {\pi * r ^ 2 * h} {3}$

Where:

A: It's the radius of the base

h: It is the height of the cone

Substituting we have:

$V = \frac {\pi * (12) ^ 2 * 15} {3}\\V = \frac {\pi * 144 * 15} {3}\\V = \frac {\pi * 2160} {3}\\V = 720 \pi \ cm ^ 3$

Answer:

$V = 720 \pi \ cm ^ 3$

Answer:

Step-by-step explanation:

The radius of a cone is the radius of its circular base. You can find a radius through its volume and height. Multiply the volume by 3. For example, the volume is 20.

Find (4.54×10^8)-(3.98×10^8)

horrorfan [7]

Answer:

$5.6 *10^7$

Step-by-step explanation:

Given

$(4.54*10^8)-(3.98*10^8)$

Required

Solve

$(4.54*10^8)-(3.98*10^8)$

Apply distributive law of algebra

$(4.54 - 3.98) *10^8$

Evaluate the expression in bracket

$(0.56) *10^8$

Remove bracket

$0.56 *10^8$

When a number is in standard form: $a * 10^n$

The value of a must be: $1 \le a \le 10$

So, the expression becomes:

$5.6 *10^{-1}*10^8$

Apply law of indices

$5.6 *10^{-1+8}$

$5.6 *10^7$

Write the rule for finding a point translated vertically k units up. 2. Use this rule to find the coordinates for (−3, −6) when

Alex17521 [72]

Answer:

Rule is (x, y+k)

New point is (-3,9)

Step-by-step explanation:

A point translated vertically k units up means the x coordinate remains the same in the translation but the y coordinate is increased by k units

This can be represented mathematically as;

Let;s assume the point to be A with coordinates (x,y) then to get the image of the point under a vertical translation k units up you add k to the y coordinate value.

Given ;

$A=(\frac{x}{y} )\\\\T=(0,k)\\\\A'=(\frac{x}{y} )+(\frac{0}{k} )=(\frac{0+x}{y+k} )\\\\A'=\frac{x}{y+k} =(x,y+k)$

where T is the translation

In the question

Given (-3,-6) and T is (0,5) the new coordinate will be

$=(\frac{-3}{4}) +(\frac{0}{5} )=\frac{-3}{9} =(-3,9)$

A sales manager collected data on annual sales for new customer accounts and the number of years of experience for a sample of 1

Step-by-step explanation:

Given :

Years of experience (X) :

Annual sales (Y) :

105

106

122

120

113

134

The estimated regression equation obtained is :

y = b0 + b1x

b0 = 82.82967

b1 = 3.46061

ŷ = 3.46061X + 82.82967

The change in annual sales for every year of experience is given by the slope value, b1 = 3.46061 = 3.5 (1 decimal place)

The Coefficient of determination R² = 0.8477 = 0.848 ( 3 decimal place).

The Coefficient of determination gives the proportion of explained variance.

About 84.8% percent variation in annual sales can be explained by years of experience of the sales person.

Using the regression equation :

ŷ = 3.46061X + 82.82967

Years of experience, x = 8

ŷ = 3.46061(8) + 82.82967 = 110.514

111 = (to the nearest whole number)
