How would you convince a fellow student that the number 0.57 is a rational number? (5+ sentences please) Please help me with this i have to turn it in in a few minutes.
Answer: 0.57 = 57/100 this means it has to be rational.
Explanation: You have to explain to them that any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions. An integer can be written as a fraction simply by giving it a denominator of one, so any integer is a rational number.
The decimal number 0.57 is converted to a rational number 57/100.
The given decimal number is 0.57.
We need to write the given decimal number in rational form.
What is a rational number?The word 'rational' originated from the word 'ratio'. So, rational numbers are well related to the concept of fractions which represent ratios. In other words, If a number can be expressed as a fraction where both the numerator and the denominator are integers, the number is a rational number.
To convert 0.57 to a rational number, divide 57 by 100 because after the decimal point there are two digits.
That is, 57/100
Therefore, the decimal number 0.57 is converted to a rational number 57/100.

Given the expression: 4x10 − 64x2
Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)
Part B: Factor the entire expression completely. Show the steps of your work. (6 points)
Answer:
Step-by-step explanation:
a) 4x¹⁰ = 2² * x¹⁰
64x² = 2⁶ *x²
GCF = 2² * x² = 4x²
b) 4x¹⁰ - 64x² = 4x²*(x⁸ - 16)
=4x² *[ (x⁴)² - 4²]
= 4x² * (x⁴ + 4) (x⁴ - 4)
= 4x² * (x⁴ + 4)* [(x²)²- 2²]
=4x² * (x⁴ + 4) * (x² + 2)(x² - 2)

For z = -3 + 5i, evaluate \($z \overline{z}.$\)
(Note: \($\overline{z}$\) denotes the conjugate of z.)
Answer:
\(\underline{ \boxed{z\overline{z} = 34}}\)
Step-by-step explanation:
\(if \: z = -3 + 5i \\then \: \overline{z} = - (3 + 5i) \\ hence \: z\overline{z} = (-3 + 5i)( - 3 - 5i) \\ z\overline{z} = 9 + 15i - 15i - {(5i)}^{2} \\ z\overline{z} = 9 - (25 ){i}^{2} \\ z\overline{z} = 9 - (25)( - 1) \\ z\overline{z} = 9 + 25 \\ \underline{ \boxed{z\overline{z} = 34}}\)
♨Rage♨
Answer:
34
Step-by-step explanation:
Here z = -3 + 5i and the complement of this is
z-comp = -3 - 5i.
Multiplying these two quantities together, we get
9 -25i² = 9 + 25 = 34

The state of colorado is 4 cm long and 3 cm wide on a map. A cartographer wants to use a scale factor of 2.5 to enlarge the map. What is the area of the enlarged map?
A:12 square cm
B:30 square cm
C:35 square cm
D:75 square cm
Answer:
D. 75 cm²
Step-by-step explanation:
We are asked to find the area of a scaled map.
What is a Scale Factor?A scale factor is a change in the size, or ratio of a shape, or object.
The value of the scale factor represents how much larger the shape or object will become.
First, let's identify what is given to us.
Given:
The map of Colorado is 4 cm long and 3 cm wide.We have to enlarge the map with a scale factor of 2.5.We should begin by enlarging the map with the given scale factor. In order to find the dimensions of the scaled map, we should multiply the given dimensions of the original map by the scale factor.
Multiply:
\(4 \times 2.5 = 10 \ cm\)
\(3 \times 2.5 = 7.5 \ cm\)
Next, we should find the area of the scaled map by multiply the dimensions together.
\(A = L \times W\)
Multiply:
\(A = 10 \times 7.5\)
\(A = 75 \ cm^{2}\)
The area of the scaled map is D. 75 cm².
Use a number line to order the numbers from least to greatest.
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25

\(\frac{16}{27}\)
Step-by-step explanation:
From the table, we notice that the total number of students is:
\(3+10+8+6=27\)
Then, along the second column of the table, we notice that the number of students who do not have a brother is:
\(10+6=16\)
So, the probability that a randomly chosen student does not have a brother is:
\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)

Find an equation in standard form for the hyperbola with vertices at (0, ±8) and asymptotes at y = ±4 divided by 3.x. y squared over 9 minus x squared over 16 = 1 y squared over 36 minus x squared over 64 = 1 y squared over 64 minus x squared over 9 = 1 y squared over 64 minus x squared over 36 = 1
Answer:
y^2 / 64 - x^2 /36 =1
Step-by-step explanation:
hyperbola with vertices at (0, ±8)
asymptotes at y = ±4/3x
The general form is
y^2 /a^2 - x^2/ b^2 =1
where the asymptote is y = ± a/b x
but we also have The vertex is ( 0 ,a)
rewriting the asymptote as 8/6 so a =8 and b = 6
y^2 / 8^2 -x^2/6^2 = 1
y^2 / 64 - x^2 /36 =1
