For what value of k is the trinomial x2 - 6x + k a perfect square?
Answers
Answer:
9
Step-by-step explanation:
[tex]x^2-6x+k\\= x^2-6x + 9 + (-9)+k\\=(x-3)^2+k-9[/tex]
So in order this expression to be a perfect square we need k-9=0. Thus k =9.
Find the total surface area of the following cone. Leave your answer in terms of Pi. 4cm 3cm
Answers
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

The scale factor is
1 : 9.5×10²⁰ as we make our galaxy as small as 1 m.The distance to Andromeda would be:

b. How many positive real zeros does the function have? How can you tell?
Answers
9514 1404 393
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.

If the elevation of Lake Superior is 186 feet above sea level and the elevation of the Caspian Sea is 17 feet below sea level, find the difference of the two elevations.
Answers
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.
How to calculate the difference between the two elevation?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.

Rational numbers have repeating patterns, like 0.9898989898989898… where it’s just 98 over and over.
Irrational number do not have a repeating pattern.
In your number, there’s one more 8 each time, so 98, then 988, then 9888, then 98888, and so on. So it’s not repeating. Because it’s not repeating, you know it’s irrational.

Step-by-step explanation:
It's not too difficult, but you can get wrapped around the axle. Here are the rules:
the opposite of a positive number is a negative numberthe opposite of a negative number is a positive numberThat is, turning a number to its opposite is just changing its sign.
__
If you layer these rules, you find ...
the opposite of (the opposite of a positive number) is a positive number
The first rule tells you the statement in parentheses is a negative number, and the second rule tell you its opposite is a positive number.
That is, a double opposite gets you back where you started. In short, any even number of minus signs cancel each other.

Use your knowledge of the definitions of validity, soundness, strength, and cogency to determine which of the following statements are true.
a) To check an argument's deductive validity, you should first ask whether the argument is sound.
b) Some inductive arguments are neither cogent nor uncogent.
c) If a deductive argument has false premises and a false conclusion, then the argument could be valid.
d) All strong inductive arguments are equally strong.
e)An inductive argument cannot be both weak and uncogent.
f) If an argument is deductively valid and has premises that are all true, then the argument is cogent.
g) All deductive arguments are either completely valid or completely invalid.
h) To have a cogent inductive argument, the premises must not ignore a piece of evidence that would require a different conclusion.
i) If an argument is deductively valid, then at least one of its premises must actually be true.
j) A statement that is true is a sound statement.
k) No sound deductive arguments are invalid arguments.
l) If a deductive argument is unsound, the argument's premises cannot all be true.
m) If an inductive argument is strong, then the argument's conclusion must be true.
n) A weak inductive argument cannot be cogent.
o) In an invalid deductive argument, it is impossible for the premises to be true and the conclusion to be false simultaneously.

How do you convert 1.6 (6repeating) as a fraction?
Answers
9514 1404 393
Answer:
5/3
Step-by-step explanation:
In general, you count the number of repeating digits and use that in the following script.
name the number: x = 1.666...multiply by 10 to the power of the number of repeating digits: 10¹x = 16.666...subtract the original number. The repeating digits should cancel. 10¹x -x = 9x = 15.000...divide by the coefficient of the variable: x = 15/9reduce the fraction: x = 5/3 = 1 2/3The 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)

Max is shopping for commercial auto insurance for the company vehicle. He is provided two quotes: $2200 for a 12-month policy or $925 for a 6-month policy. What is the first step in determining which policy is cheaper?
Answers
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
