Answer:

  V = (1/3)πr²h

Step-by-step explanation:

The volume of a cone is 1/3 the volume of a cylinder with the same radius and height.

  Cylinder Volume = πr²h

  Cone Volume = (1/3)πr²h

where r is the radius (of the base), and h is the height perpendicular to the circular base.

_____

Comment on area and volume in general

You will note the presence of the factor πr² in these formulas. This is the area of the circular base of the object. That is, the volume is the product of the area of the base and the height. In general terms, ...

  V = Bh . . . . . for an object with congruent parallel "bases"

  V = (1/3)Bh . . . . . for a pointed object with base area B.

This is the case for any cylinder or prism, even if the parallel bases are not aligned with each other. (That is, it works for oblique prisms, too.)

Note that the cone, a pointed version of a cylinder, has 1/3 the volume. This is true also of any pointed objects in which the horizontal dimensions are proportional to the vertical dimensions*. (That is, this formula (1/3Bh), works for any right- or oblique pyramid-like object.)

__

* in this discussion, we have assumed the base is in a horizontal plane, and the height is measured vertically from that plane. Of course, any orientation is possible.

The solution to the given expression is log (9) + log (4).

The logarithm function is defined as the inverse of exponential function. If b = e^(a) then a is defined as a = log(b).

The logarithm of the product of two numbers is equal to the sum of their individual logarithms. The logarithmic properties can be written as log(ab) = log(a) + log(b), log(a/b) = log(a) - log(b) and log(aⁿ) = nlog(a).

The given expression is log(9 × 4).

It can be rewritten as,

log(9 × 4)

Use the property of the logarithm log(ab) = log(a) + log(b) to obtain,

log(9 × 4) = log(9) + log(4)

Hence, the given logarithmic expression can be solved as log (9) + log (4).

Answer:

x = -1 or 5

Step-by-step explanation:

From the expression (x +1) (x - 5)

We’re to solve for x.

Therefore,

x + 1 = 0

Subtract one from both sides

x + 1 - 1 = 0 - 1

x = -1

x - 5 = 0

Add five to both sides

x - 5 + 5 = 0 + 5

x = 5

Answer:

(1,0)

Step-by-step explanation:

The point that f(x) = log₂x and g(x) = log₁₀x have in common is where both graph intersect.

Recall that the logarithm of 1 is 0.

This implies that, when we plug in x=1 into both function we get 0.

g(1) = log₁₀1=0

f(1) = log₂1=0

This means the two graphs intersect at (1,0)

Therefore the graphs of f and g have (1,0) in common

The probability that a point chosen inside a circle will also be inside a square is π/4.

The probability that a point chosen inside a circle will also be inside a square can be determined by comparing the areas of the circle and the square. Let's assume that the circle has a radius of r and the square has sides of length 2r. The area of the circle is πr2 and the area of the square is (2r)2 = 4r2. Therefore, the probability of the point being inside the square is given by the ratio of the area of the circle to the area of the square: P = (πr2) / (4r2) = π/4.

The correct answer is option C as the shown triangle is obtuse.

Based on the image, the triangle has the following angles:

Step 1: Sum of angles in a triangle

The sum of the angles in any triangle is always 180 degrees.

Therefore:

[tex]132^0 + 36^0 + 12^0 = 180^0[/tex]

Step 2: Analyze angle measures

Looking at the triangle, the following are the angle measures:

One angle [tex](132^0)[/tex] is greater than [tex]90^0[/tex].

There are no angles exactly equal to [tex]90^0[/tex].

All other angles [tex](36^0,12^0)[/tex] are less than [tex]90^0[/tex].

Step 3: Triangle classification

Based on the angle measures, the following is evident.

The triangle has one angle greater than [tex]90^0[/tex], so it cannot be acute (where all angles should be less than [tex]90^0[/tex]).

The triangle does not have any angles equal to [tex]90^0[/tex], so it is not right.

Since it has one angle greater than [tex]90^0[/tex], the triangle is classified as obtuse.

Thus the triangle is obtuse and it corresponds to option C.

Answer:

x = -75

Step-by-step explanation:

x/-5=15

x = 15 x -5

x = -75

Answer:

-75

Step-by-step explanation:

Step by step solution :

Step  1  :

            x

Simplify   ——

           -5

Equation at the end of step  1  :

  x    

 —— -  15  = 0

 -5    

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  -5  as the denominator :

         15     15 • -5

   15 =  ——  =  ———————

         1        -5  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

x • -1 - (15 • 5)     -x - 75

—————————————————  =  ———————

        5                5  

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  -x - 75  =   -1 • (x + 75)

Equation at the end of step  3  :

 -x - 75

 ———————  = 0

    5  

Step  4  :

When a fraction equals zero :

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 -x-75

 ————— • 5 = 0 • 5

   5  

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -x-75  = 0

Solving a Single Variable Equation :

4.2      Solve  :    -x-75 = 0

Add  75  to both sides of the equation :

                     -x = 75

Multiply both sides of the equation by (-1) :  x = -75

One solution was found :

                  x = -75

1.29 % is converted to decimal as 0.0129

Solution:

"Percent" means "per 100" or "over 100"

To convert 1.29% to a decimal rewrite 1.29 percent in terms of per 100 or over 100

Given percentage is 1.29 %

1.29 % = 1.29 over 100

[tex]1.29 \% = \frac{1.29}{100}[/tex]

1.29 over 100 is the same as 1.29 divided by 100

Completing the division we get:

[tex]1.29 \% = \frac{1.29}{100} = 0.0129[/tex]

Thus the given 1.29 % is converted to decimal as 0.0129

Source:

Previous question that can be found at brainly

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Miles per week Charles rode his bike = 19

Miles every Monday Charles bikes = 2.2

Miles every Tuesday Charles bikes = ?

Miles every Wednesday Charles bikes = 3.8

Miles every Thursday Charles bikes = ?

Miles every Friday Charles bikes = 5.4

Charles rode 1.6 miles more on Thursday than Tuesday

2. Find the number of miles he rode on Tuesday and Thursday.

x = Miles Charles rides every Tuesday

1.6 + x = Miles Charles rides every Thursday

Now, we can write our equation to solve for x, this way:

2.2 + x + 3.8 + x + 1.6 + 5.4 = 19

2x + 13 = 19

2x = 19 - 13

2x = 6

x = 3 ⇒ x + 1.6 = 4.6
