What is a decimal number?
A decimal is a number with a whole and a fractional component. Decimal numbers, which are in between integers, are used to express the numerical value of full and partially whole amounts. The decimal point is the dot that separates the whole number from the fractional part of the number. An example of a decimal number is 34.5.Here are four decimal numbers:

Answer:
B) 0.702, 0.73, 0.76, 0.91
Step-by-step explanation:
The given set of decimal numbers (in any order) is:
0.702, 0.76, 0.91, 0.73Each number has zero units.
Comparing the digits in the tenth place, all the numbers have 7 tenths except 0.91 which has 9 tenths. Therefore, 0.91 is the largest number as 9 > 7.
Comparing the digits in the hundredths place of the other three numbers, 0.702 is the smallest number as it has zero hundredths.
As 0.73 has 3 hundredths and 0.76 has 6 hundredths, this means that 0.73 is the second smallest number as 3 < 6.
Therefore, the given set of decimals in order from smallest to largest is:
0.702, 0.73, 0.76, 0.91Rewrite the function by completing the square. h ( x ) = x 2 + 3 x − 18 h(x)=x 2 +3x−18
The quadratic function h (x) = x^2 + 3x − 18 by completing the square is witten as h(x) = (x + 1.5)^2 - 20.25.
We are given a quadratic function:
h (x) = x^2 + 3x − 18
We need to rewrite the function by completing the square.
We can see the coefficient of x is 3.
So, we will add and subtract the square of half that.
So, find the square of half of 3, we will get;
(3 / 2)^2 = 9 / 4 = 2.25
add and subtract the square of half of 3 from the given function, we will get;
h(x) = x^2 +3x + -18 2.25 -2.25
arrange the expression, we will get;
h(x) = (x^2 +3x +2.25) -18 -2.25
write the expression in parentheses as a square, and simplify the constant, we will get;
h(x) = (x + 1.5)^2 - 20.25
So, the square function is written as h(x) = (x + 1.5)^2 - 20.25.
Thus, the quadratic function h (x) = x^2 + 3x − 18 by completing the square is witten as h(x) = (x + 1.5)^2 - 20.25.

Can someone help me with this question please !!
I have to know how to solve it to pass my exam
I'll give brainly to the right answer .
Answer:
Step-by-step explanation:
you'll need to know L'Hôpital's Rule. Obviously this problem goes to zero in the denominator if you let x go to zero, which is a big problem :P sooo use L'Hopital's rule to solve this messy problem.
L'Hoptial's rule takes the advantage that you can find the derivative of something but still find it's limit just like you didn't take a derivative. soo
take derivative of numerator and denominator separately
remember how to take derivative of sin^2(3x) ??
pull the two down, then chain rule
d/dx (sin^2(3x) = 2sin(3x) * cos(3x) * 3 = 6*sin(3x)*cos(3x)
d/dx (4x^2) = 8x
we still have the same issue if we take the limit if x goes to zero :0
but it's okay... just take L'Hopitals' again :P
d/dx (6*sin(3x)*cos(3x)) = 6*cos(3x) *3 *(-sin(3x)*3 = 54*cos(3x)*(-sin(3x))
d/dx (8x) = 8
now we can let the limit go to zero
lim ( x ->0)[54*cos(3x)*(-sin(3x)) / 8]
we can see that sin(x) will get closer and closer to zero so we have 0/8
so we can fairly say, without guessing, that yes... this limit goes to zero as X goes to zero. :) nice
Write an equation for the nth term of the arithmetic sequence
The equation for the nth term of the arithmetic sequence is [tex]a_{n}[/tex] = 25 - 4n
The nth term of the arithmetic sequence:An arithmetic sequence or arithmetic progression is a series of numbers with a common difference. For example 1, 2, 3, 4... is an Arithmetic sequence with a common difference 1. In an Arithmetic sequence, the difference between every two consecutive terms will be equal.
The formula for the nth term of a sequence is given below
=> [tex]a_{n}[/tex] = a + (n-1)d
where a is the first term and d is a common difference.
Here we have
21, 17, 13 ... is the arithmetic sequence
Where first term a = 21
and common difference d = term2 - term1 = 17 - 21 = - 4
As we know the nth term of AP, [tex]a_{n}[/tex] = a + (n-1)d
=> [tex]a_{n}[/tex] = 21 + (n-1)(-4)
=> [tex]a_{n}[/tex] = 21 - 4n + 4
=> [tex]a_{n}[/tex] = 25 - 4n

write an equation of the line that contains point (-2,2) and is perpendicular to x - 2y = 5 in standard form.
Answer:
[tex]y = -2x-2[/tex]
Step-by-step explanation:
A line being perpendicular means that it has a slope that is an opposite reciprocal of the other line.
In this case:
[tex]x - 2y = 5\\-2y = -x + 5\\y = \frac{x}{2} - \frac{5}{2}[/tex]
The slope of this line is [tex]\frac{1}{2}[/tex] and so the perpendicular slope would be [tex]-2[/tex].
Using the point slope form:
[tex]y - y_1 = m(x-x_1)\\[/tex]
Substitute values:
[tex]y - y_1 = m(x-x_1)\\y - 2 = -2(x+2)\\y -2 = -2x-4\\y = -2x-2[/tex]

The tree died about ] years ago.
Do not round until the final answer. Then round to the nearest whole number.)
Answer:
Time 2 540 years
Step-by-step explanation:
T = 5 600 yares - Half-life
73% - Carbon content
N = 0.73·N₀
Decay constant:
λ = ln 2 / T = 0.693 / 5600 ≈ 0.000124 (years)⁻¹
Law of radioactive decay:
N = N₀·e^(-λ·t)
0.73·N₀ = N₀·e^(-λ·t)
0.73 = e^(-λ·t)
ln (0.73) = -λ·t
t = ln (0.73) / (-λ) = ln (0.73) / (- 0.000124) ≈ 2 540 years

Suppose Tom borrows $4000 at an interest rate of 3% compounded each year.
Assume that no payments are made on the loan.
Follow the instructions below. Do not do any rounding.
(a) Find the amount owed at the end of 1 year.
(b) Find the amount owed at the end of 2 years.
The amount owed at the end of 1 year is $4120 and by the end of 2 years, $4243.60 when Tom borrows $4000 at an interest rate of 3% compounded each year.
What is compound interest?The interest you earn on interest is known as compound interest. Simple math can be used to demonstrate this: if you have $100 and it earns 5% interest annually, you will have $105 at the end of the first year. You will end up with $110.25 at the end of the second year. In order to calculate compound interest, multiply the principal of the original loan by the annual interest rate multiplied by the number of compound periods minus one.
Here,
principle amount=$4000
rate of interest=3%
For first year,
A=P(1+r/n)^(nt)
A=4000(1+3/12)^12*1
A=$4,120.00
For first year,
A=P(1+r/n)^(nt)
A=4120(1+3/12)^12*1
A=$4,243.60
When Tom borrows $4000 at an interest rate of 3% compounded annually, the total amount due at the end of one year is $4120, and at the end of two years, it is $4243.60.

What is Linear Inequality?
The mathematical expression with unequal sides is known as an inequality in mathematics. Inequality is referred to in mathematics when a relationship results in a non-equal comparison between two expressions or two numbers. In this instance, any of the inequality symbols, such as greater than symbol (>), less than symbol (), greater than or equal to symbol (), less than or equal to symbol (), or not equal to symbol (), is used in place of the equal sign "=" in the expression. Polynomial inequality, rational inequality, and absolute value inequality are the various types of inequalities that can exist in mathematics.
The symbols "" and ">" signify tight inequalities, while "" and "" signify slack inequalities. A linear inequality looks precisely like a linear equation, but the symbol connecting two expressions is different.

300 metros = 300/1000 = 0.3 kilómetros
Entonces:
300 metros por minuto = 300metros/minuto

now let's see how many liters we have hmmm 2 of hazel, 1 of alcohol and the rest in boric acid, to make a total of 5 liters, so boric acid must be 2, since 2 + 1 + 2 = 5.

how much alcohol is there in 95% of 1? well, no to bore you to death, is just 0.95 liters, and we know the boric acid has no alcohol.
so in the 5 liters of the lotion, we have 0.28 liters plus 0.95 liters of alcohol total, that's 1.23 liters total.

Step-by-step explanation:
If we graph the function with the help of the given table,
Since, there is a common difference in each term of 'cost of gym membership'
d = 61 - 25.5 = 35.5
d = 96.5 - 61 = 35.5
Graph will represent a linear function.
Let the equation of the line is,
y - y' = m(x - x')

Two points lying on the graph are (1, 25.5) and (2, 61).
Slope of the line =

Equation of the line passing through (1, 25.5) having slope 'm' = 35.5
y - 25.5 = 35.5(x - 1)
