(when multiplying decimals do not line up the dot and solve it as if there was no decimals point. when you get your answer count the amount of digits on the right side of the number going to the left on your answer.
in this case there are three digits on the right side of the decimals you count three spaces to the left of your answer wich is 574. put the decimal point infront of the 5 and you get you answer. 70.574
The graph of f(x)=-vx is shifted to the right five units.
What is the domain?
Answer:
All x-values larger than or equal to 5 ([tex]x\geq 5[/tex])
Step-by-step explanation:
Notice that the graph of
[tex]f(x)=-\sqrt{x}[/tex]
is defined for all real x-values larger than or equal to zero, since the square root is defined only for such values.
When we shift the graph to the right 5 units, the function becomes:
[tex]f(x)=-\sqrt{x-5}[/tex]
then the radicand x-5 must be larger than or equal to 0 in order to render real values. Then we have:
[tex]x-5\geq 0\\x\geq 5[/tex]
which means that now the Domain becomes the following set (in set builder notation):
[tex]Domain=\left \{ x\,|\,x\geq 5 \right \}[/tex]

Riddle - You enter a room. 2 dogs, 4 horses 1 giraffe and a duck are lying on the bed. 3 chickens are flying over two chairs. How many legs are on the ground?
Answer:
Trick question, either 8 legs because of the two chairs or none.
Step-by-step explanation:
The dogs and everything aren't on the ground. I think the anwser is either 8 or none.
Answer:
The number of legs on the ground are 10.
Step-by-step explanation:
Given information:
2 dogs , 4 horses and 1 giraffe and a duck are laying on the bed.
3 chickens are flying over two chairs .
Now, in the riddle the specific type of leg is not mentioned but the information is given about the bed and chair.
So, one need to consider the legs of bed and chair too, also the person entering in the room is on the ground so the legs of the person will also be counted.
Hence, total number of legs on the ground will be:
legs of (1 bed + 2 chairs + 1 person)
Hence
Number of legs (N) = 4+8+2
N=10
Hence, the number of legs on the ground are 10.

Trying to factor by pulling out :

Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -7x + 3
Group 2: 10x3 - 3x2
Pull out from each group separately :
Group 1: (-7x + 3) • (1) = (7x - 3) • (-1)
Group 2: (10x - 3) • (x2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.

Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 10 and the Trailing Constant is 3.
The factor(s) are:
of the Leading Coefficient : 1,2 ,5 ,10
of the Trailing Constant : 1 ,3
Let us test ....

The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms

Step-1 : Multiply the coefficient of the first term by the constant 5 • -3 = -15
Step-2 : Find two factors of -15 whose sum equals the coefficient of the middle term, which is 1 .
-15 + 1 = -14

The quotient when 10x³-3x²-7x+3 divided by 2x-1 is -21/8.
To calculate the quotient of the equation 10x³-3x²-7x+3 when it is divided by 2x-1, we use the quotient theorem.
Remainder theorem
The quotient theorem states that if f(x) is divided by x-a, then the remainder is f(a).
From the question,
Given:
f(x) = 10x³-3x²-7x+3............. Equation 1diveded by 2x-1The quotient is f(1/2), we substitute the value of x as 1/2 into equation 1
f(1/2) = 10(1/2)³-3(1/2)²-7(1/2)+3f(1/2) = (10/8)-(3/4)-(7/2)+3f(1/2) = -21/8Hence, The quotient when 10x³-3x²-7x+3 divided by 2x-1 is -21/8.

A desk is 2 meters long and 1 meter wide. The desk needs to be represented in a scale drawing of an office that uses a scale of 1 centimeter = 0.5 meter. What are the dimensions of the desk in the drawing?
Answer:
Thus, the dimensions of the desk in the drawing are 4 cm long and 2 cm wide.
Step-by-step explanation:
Scaling
The scale factor established to represent a desk 2 meters long and 1 meter wide is:
1 centimeter = 0.5 meter
We need to convert the real dimensions to the scaled dimensions. To complete the task, it's a good idea to multiply the real dimensions by the ratio:
[tex]\displaystyle \frac{1\ cm}{0.5\ m}[/tex]
to get the scaled dimensions.
The length of 2 meters is scaled to:
[tex]\displaystyle 2\ m\frac{1\ cm}{0.5\ m}=4\ cm[/tex]
And the width of 1 meter is scaled to:
\displaystyle 1\ m\frac{1\ cm}{0.5\ m}=2 cm
Thus, the dimensions of the desk in the drawing are 4 cm long and 2 cm wide.

Answer:
x=2
Step-by-step explanation:
To find the axis of the simmetry of parabola ( the curve of the quadratic function) we have to find the x of the top point of the parabola.

Rachel runs 3.2 miles each weekday and 1.5 miles each day of the weekend. How many miles will she have run in 6 weeks?
Rachel will have ran 114 miles in six weeks.
There's five weekdays in a week: (3.2 x 5) = 16 miles
There's two days in a weekend: (1.5 x 2) = 3 miles
16 [weekday] + 3 [weekend] = 19 miles [7-day week]
(19 x 6) = 114 miles

Suppose that there are 327 members of a professional organization, of which 164 are over the age of 50. What is the probability that a randomly selected member of the organization is over the age of 50?
Answer:
0.502
Step-by-step explanation:
There are 327 members of a professional organization, of which 164 are over the age of 50.
The probability that a randomly selected member of the organization is over the age of 50 is calculated as:
Probabilty = 164 members/327 members
= 0.501529052
Approximately = 0.502
Therefore, the probability of the randomly selected member is over the age of 50 is 0.502.
