A. Yes, because it has two straight lines.
B. Yes, because it passes the vertical line test.
O C. No, because it is not a curve.
D. No, because it fails the vertical line test.
Answers
Answer:
D. No, because it fails the vertical line test
Step-by-step explanation:
A function can only have 1 output for each input. If you are able to draw a vertical line and it touches the graph twice, then it has failed the vertical line test and is therefore not a function.

Clare’s aunt used a credit card to pay $42 for an outfit. Six weeks later, the credit card company charged her 2% interest.
a. How much is the 2% interest?
b. How much will Clare’s aunt have to pay in total?
Answers
Answer:
0.84$ and 42.82$
Step-by-step explanation:
2% is equivalent to 2/100
So, 42$ x [tex]\frac{2}{100}[/tex] = 84/100 = 0.84$ (the 2% interest)
And the total the aunt has to pay equals to = 42$ + 0.84$ =42.84$

Answers
Answer:
11/12 square feet
Step-by-step explanation:
The area is the product of length and width. Multiplication of mixed numbers is often easily done by converting to improper fractions.
A = LW
A = (3 2/3 ft)(1/4 ft)
A = (11/3)(1/4) ft² = 11/12 ft²
The area is 11/12 square feet.

Which Venn diagram correctly represents the relationship between rational numbers and irrational numbers?
PLEASE HELP!!!
Answers
Answer:
The answer is C.
Step-by-step explanation:
Because rational numbers are part of the irrationals.
There are two major subsets of Real numbers which are rational numbers and irrational numbers
The correct option for the Venn diagram that correctly represents the relationship between rational numbers and irrational numbers is option A because;
A. Rational numbers and irrational numbers have no numbers in common
The reason the above selection is correct is as follows:
Rational numbers are denoted by the capital letter Q, and they can be represented by the ratio of two integers, a, and b, as follows;
[tex]Q = \mathbf{\dfrac{a}{b}}[/tex]
Where;
a, and b, are whole number integers
Rational numbers are one of the two major subsets of real numbers, R
Example of rational numbers are [tex]\dfrac{1}{2}[/tex], 0.85, and [tex]\dfrac{4}{1}[/tex] = 4
Therefore, integers are rational numbers
Irrational numbers: Irrational numbers are real numbers that are not rational numbers, and they are represented by the capital letter, I, they cannot be represented as the ratio of two integers a, and b
Example of irrational numbers are π, √2, and √3
Rational numbers and irrational numbers are different subsets of Real numbers and they have no element in common, therefore, the correct option is option A

Answers
Answer:
La temperatura del aire a una altitud de 15000 metros sobre el nivel del mar es -66 ºF.
Step-by-step explanation:
Dada la relación de linealidad, construimos una función lineal de la temperatura del aire en función de la altitud con respecto al nivel del mar, la cual es:
[tex]T(h) = T_{L} + \frac{T_{H}-T_{L}}{h_{H}-h_{L}} \cdot h[/tex], [tex]0\,m \leq h \leq 20000\,m[/tex] (Eq. 1)
Donde:
[tex]T_{L}[/tex] - Temperatura del aire a nivel del mar, medida en grados Fahrenheit.
[tex]T_{H}[/tex] - Temperatura del aire a determinada altitud, medida en grados Fahrenheit.
[tex]h_{L}[/tex] - Altura del nivel del mar, medida en metros.
[tex]h_{H}[/tex] - Altura determinada, medida en metros.
[tex]h[/tex] - Altitud con respecto al nivel del mar, medida en metros.
[tex]T(h)[/tex] - Temperatura del aire a una altitud con respecto al nivel del mar, medida en grados Fahrenheit.
Si sabemos que [tex]T_{L} = 60\,^{\circ}F[/tex], [tex]T_{H} = 18\,^{\circ}F[/tex], [tex]h_{L} = 0\,m[/tex], [tex]h_{H} = 5000\,m[/tex] y [tex]h = 15000\,m[/tex], la temperatura del aire a esa altitud es:
[tex]T(15000\,m) = 60\,^{\circ}F + \frac{18\,^{\circ}F-60\,^{\circ}F}{5000\,m-0\,m} \times 15000\,m[/tex]
[tex]T(15000\,m) = -66\,^{\circ}F[/tex]
La temperatura del aire a una altitud de 15000 metros sobre el nivel del mar es -66 ºF.

The dimensions of this figure are changed so that the new surface area is exactly 1/4 what it was originally.
Answers
Step-by-step explanation:
I assume the changes to the dimensions were made by using the same factor for each dimension, right ?
so, what do we need to do or calculate ? what is the desired result ?
the surface areas ? the new dimensions ? the volume ?
or only the factor of how much the dimensions changed, when the surface area was changed to 1/4 ?
????
I assume the last one, because there is so little information about what to do.
the surface area is calculated based on the areas of the various rectangles in the surface of the object.
each rectangle area is the result of multiplying 2 dimensions.
as the whole surface area shrinks by the factor 1/4, it means that every rectangle on the surface also shrinks by the factor 1/4.
and this factor 1/4 is the result of multiplying 2 dimensions. each dimension was changed by multiplying it with the same factor as every other dimension.
so, factor×factor = 1/4
factor² = 1/4
factor = sqrt(1/4) = 1/2
so, yes, in order to shrink the surface area to 1/4 of the original size, all the dimensions need to be cut in half (multiplied by 1/2).
