The triangle formed from the height of the cone and the radius of its base is a special 3,4,5 triangle. The slant height is 5cm.

Recall that the area of a circle = pi*r^2

Substitute 3 in for r

Area = pi * (3)^2 = 9pi

SA = pi*r*l + B

Substitute our values into the equation

SA = pi * 3 * 5 + 9pi

SA = 15pi + 9pi

SA = 24pi cm^2

.1 Simplify: 5n(2n3+n2+8)+n(4-n).

Solution:

5n(2n3+n2+8)+n(4-n).

= 5n × 2n3 + 5n × n2 + 5n × 8 + n × 4 - n × n.

= 10n4 + 5n3 + 40n + 4n – n2.

= 10n4 + 5n3 + 44n – n2.

= 10n4 + 5n3 – n2 + 44n.

Answer: 10n4 + 5n3 – n2 + 44n

Answer:

203

Step-by-step explanation:

186+17= 203

(You add because the 17 is originally negative, therefore, the negative and subtraction sign cancel eachother out and cause the equation to become an addition problem. (edited)

The difference between the two elevations is 203.

What is the difference between the two numbers?

The difference between two numbers implies the actual distance between that two points in the number line.

Here, the elevation of Lake Superior is 186 feet above the sea level, it can be treated as (+186)feet

and the elevation of Caspian Sea is 17 feet below of sea level, it can be treated as (-17)feet.

Now, the difference between two elevation of the lake is = 186-(-17)feet

=203 feet.

The first step in determining the cheaper policy is to determine the cost of each insurance per month. This is done by dividing total insurance cost by total months

To determine the cost of insurance per month, divide the total cost of the insurance by the months

Monthly cost of insurance = total cost / total month

$2200 / 12 = $183.33

$925 / 6 = $154.17

Based on the above calculations, the $925 for a 6-month policy is cheaper

Answer:

  5/3

Step-by-step explanation:

In general, you count the number of repeating digits and use that in the following script.

The improper fraction is 5/3.

__

Additional comment

When the repeat starts at the decimal point, you can create the fraction by dividing the repeating digits by the same number of 9s.

 1/7 = 0.142857...(6-digit repeat)

  = 142857/999999

When the repeat has a number of digits, reducing the fraction isn't always easy.

__

If the repeat doesn't start at the decimal point, you can use the above script, or scale the fraction according to where it starts.

Example: 0.4333...(1-digit repeat) = 0.4 + (1/10)(0.333...) = 0.4 + (1/10)(3/9) = 4/10 +1/30 = 13/30

__

Any fraction whose denominator includes factors other than 2 or 5 will be a repeating decimal. It can be helpful to memorize the repeating decimals associated with small-integer fractions:

1/3 = 0.3...(1-digit repeat)

1/6 = 0.16...(1-digit repeat)

1/7 = 0.142857...(6-digit repeat)

1/9 = 0.1...(1-digit repeat)  --  of course 2/9, 1/3, etc are multiples of this

1/11 = 0.09...(2-digit repeat)  --  as with 1/9, multiples of 1/11 are multiples of this.

1/12 = 0.083...(1-digit repeat)

-6/5 - (-13/15) = -6/5 + 13/15 =

if you are advanced.you can see the relationship between the first triangle and the second triangle.

but if you are not advance in geometry.you can compare the side that are relative to one another.

side Ac relative to side zx

side Bc relative to side yx

and

side Ab relative to side zy

The corresponding sides as equal ratios will be AB / YZ = BC / YZ = AC / XZ. Then the correct option is D.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

In triangles ΔABC and ΔZYX,

∠C = ∠X        (Given)

∠B = ∠Y        (Given)

∠A = ∠Z        (Given)

The corresponding angles of the triangles are equal. Then the triangles ΔABC and ΔZYX are similar to each other. Then the equation is written as,

AB / YZ = BC / YZ = AC / XZ

The corresponding sides as equal ratios will be AB / YZ = BC / YZ = AC / XZ. Then the correct option is D.

Answer:

Step-by-step explanation:

Frank should have used 1.2 not 0.2 in the equation .

because its like the future value formula is FV=PV(1+i)n, where the present value PV increases for each period into the future by a factor of 1 + i. 

So, why do we add 1 to i?

When we look at most alternative rates of return, they are almost universally less than 100%. It is very difficult to make 100% on an investment over long periods of time. You would REALLY have to know what you are doing. Typically, most “alternative” rates of investment will be under 10%. So, that means that when you multiply a number that is less than 1 by itself repeatedly, it gets smaller and smaller quite rapidly.

Let’s look at what happens when we use a return of 0.06 or 6%.

For just two time periods, 0.06 * 0.06 would produce 0.0036! This is a number which is VERY much smaller, by over an order of magnitude! It is not very helpful to our cause.

Adding 1 to the alternate rate of return stabilizes the number.

1.06 * 1.06 = 1.0036 No matter how many times you perform the multiplication, (for a larger number of time periods), you thus still have a number that is “close” to 1. We then later use this as a divisor, so, the numerator is nearly, but not quite, unchanged. The tiny, leftover fractional part gives us the ability to differentiate between various investments, while keeping things on an even keel.

Answer:

  a) 4

  b) 3

Step-by-step explanation:

a. The total number of real and complex zeros is equal to the degree of the polynomial. That total is (1 negative real) + (3 positive real/complex) = 4 total zeros. The degree of the polynomial is 4.

The even degree is confirmed by the answer to part b, and by the end-behavior shown in the table, which has a tendency to -∞ for |x|→∞.

__

b. The intermediate value theorem tells you there will be zeros in the intervals (0, 1), (1, 2), and (2, 3) according to the values in the table. (The function changes sign in those intervals.) Thus there are 3 positive real zeros.

Additional comment

Stanley cannot tell anything about Descartes' rule of signs by analyzing the table of function values. To use that rule, he must have terms of the polynomial. If he has those terms, he already knows the degree of the polynomial.
