what is the range of the function shown in the graph?
a. -♾ < y < 5
b. -♾ < y < ♾
c. -♾ < y < -5
d. -5 < y < ♾
Answer:
-♾ < y < 5
Step-by-step explanation:
Range is set of all possible values for Y.
To know the range of value from graph one needs to see points on axis beyond which the curve does not move.
Alternatively, we can say range is the value of y which is limiting the movement of curve beyond those limits.
Here we can see that upper point on curve is constrained at midpoint of 4 and 6 which is point 5.
Thus, upper limit is 5
which can be written as
y<5
___________________________________
For lower limit , it
Since , the at lower end curve is extended till the end of graph and the end of graph represents infinity. Also, this infinity is on the negative side of y .
Then lower end is -♾ .
which can be written as
y> -♾
Also we can see that graph is continuous one as there is no break in the curve between 5 and -♾.
Thus range of curve is from minus infinity to 5
which can be expressed as
-♾ < y < 5
What is the probability that 2 randomly selected months have 31 days?
Answer:
31.8%
Step-by-step explanation:There are 7 months that have 31 days so,
The odds the first selected month has 31 days is 7/12
The next month there are only 6 months left with 31 days of only 11 months to choose from
so the odds for the second are 6/11
To calculate the odds they BOTH have 31 months you multiply the two odds:
(7/12) x (6/11) = 42/132 = .318 so 31.8%
The required probability is 0.318 or 31.8% (in the form of a percentage) that 2 randomly selected months have 31 days.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
There are 7 months with 31 days, therefore
The probability that the first picked month has 31 days is 7/12.
There are just 6 months left with 31 days of only 11 months to choose from the following month.
As a result, the odds for the second are 6/11.
To determine the probabilities that they both have 31 months, multiply the two odds:
⇒ (7/12) × (6/11)
⇒ 42/132
Apply the division operation,
⇒ 0.318
⇒ 31.8% in the form of a percentage
Thus, the required probability is 0.318 or 31.8% that 2 randomly selected months have 31 days.

Isaiah was given a gift card for a coffee shop. Each morning, Isaiah uses the card to buy one cup of coffee. Each cup of coffee costs $2.50 and after buying 16 cups of coffee, the card had a $5 remaining balance. Write an equation for A(x),A(x), representing the amount money remaining on the card after buying xx cups of coffee.
Answer:
$45-$2.50xx
Step-by-step explanation:
Let first of all determine the original amount on the gift card as follows
amount utilized=$2.50*16=$40
balance left after utilizing $40=$5
original amount on the gift card=amount utilized+balance left=$40+$5=$45
if xx cups of coffee is purchased ,the amount utilized would be xx*$2.50
i.e $2.50xx
The equation for the amount left would total amount on the gift card minus the $2.50xx
equation for amount remaining =$45-$2.50xx
If the questioner has duplicated x,which means he or she meant just x
equation of the amount remaining would=$45-$2.50x
A rectangular prism has a length of 19ft, a height of 19ft, and a width of 6ft. What is its volume, in cubic ft?
Answer:
[tex] \boxed{Volume \: of \: rectangular \: prism = 2166 \: {ft}^{3}} [/tex]
Explanation:
Volume of rectangular prism is same as volume of cuboid
Length = 19 ft
Width = 6 ft
Height = 19 ft
Volume of rectangular prism = Length × Width × Height
= 19 × 19 × 6
= 19² × 6
= 361 × 6

Bob the Wizard makes magical brooms. He charges 125 gold pieces for each magical broom he makes for his customers. He also charges a one-time fee of 50 gold pieces for his initial consultation. The total number G of gold pieces Bob charges is a function of x, the number of magical brooms he makes. Write the function's formula.
Answer:
y= 125x + 5o
Step-by-step explanation:
Since the constant is 125 we add the x to show each broom he makes. The one time fee is not a constant so therefore it will only be added once.
Answer:
f(x)=125g+50
Step-by-step explanation:
He is charging $125 for each gold piece so you would multiply “g” and 125.
You would add 50 as a one time fee so you add 50.
The Math Club wants to order t-shirts to recognize students who improved their performance in Algebra I for their hard work and effort. Hot Shirts charges $10 per shirt with a $15 set up charge. T-Shirt World charges $5 per shirt with a $50 set up charge.
Answer:
Cost of ordering t-shirts the same at both sides is 7
The cost is $85
Step-by-step explanation:
let x equal the number of tshirts
Hence:
15 + 10x = 50 + 5x
10x-5x= 50-15
5x = 35
35/5x
x = 7
Therefore the cost of ordering t-shirts the same at both sides is 7
The cost is $85
What is 2(n-1)+4n=2(3n-1)
Answer:
Infinite solutions
Step-by-step explanation:
Distribute the 2 to (n - 1), and distribute the 2 to (3n - 1), like so:
2(n - 1) + 4n = 2(3n - 1)
2n - 2 + 4n = 6n - 2
Add like terms (2n and 4n):
6n - 2 = 6n - 2
Subtract 6n from both sides:
-2 = -2
Since we ended up with the same term on both sides, we can't do anything else, meaning this equation has infinite solutions.

The diagram shows a right-angled triangle and a parallelogram.
24 cm side of triangle
30 cm base of parallelogram
7cm base of triangle
The area of the parallelogram is 5 times the area of the triangle.
The perpendicular height of the parallelogram is hcm.
(b) Find the value of h.
Answer:
see explanation
Step-by-step explanation:
i know this is very late but ..
area of triangle= b*h/2
24*7/2=84
and it said the parallelogram is 5 times the area so we do
84*5=420 which is the total area of the parallelogram
now to find h we need to do
420/30=14
h=14 because 30*14=420
The required value of h is 14 cm for the given parallelogram.
What is Parallelogram?A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
The area of the triangle is (247)/2 = 84 square cm.
Since the area of the parallelogram is 5 times the area of the triangle, the area of the parallelogram is 845 = 420 square cm.
The area of the parallelogram is equal to the base (30 cm) multiplied by the height (h cm), so we can set up the equation:
30h = 420
To find the value of h, we can divide both sides of the equation by 30:
h = 420/30
h = 14 cm
Thus, the required value of h is 14 cm.

Describe when you would need to solve a system of linear equations, instead of a single linear equation
Answer:
See explanation below
Step-by-step explanation:
A system of linear equations is a system that is formed when you have two or more variables, for example:
[tex]x=2y+z\\3y-4x=7y+2z\\2y+z=4x+3y[/tex]
In this case, we have 3 equations with 3 variables in total (x, y and z). Thus, we would need to solve a system of linear equations (they are linear because none of the variables have exponents).
On the other side, a single linear equation has only one variable that we need to find, for example:
[tex]3x=\frac{5}{3}[/tex]
In this case we would just have to solve for x
[tex]3x=\frac{5}{3} \\9x=5\\x=\frac{5}{9}[/tex]
Thus, we need to solve a system of linear equations when we have more than one variable (and more than one equations) as opposed to when we have just one variable and a single equation (single linear equation)

a) 16[tex]\pi[/tex]
b) Using [tex]\pi[/tex] is more accurate because it represents the exact and full value of pi, rather than an estimation or approximation like 3.14.
Step-by-step explanation:
The formula to find the volume of a cone is [tex]\frac{1}{3} \pi r^{2} h[/tex]. We know the radius is 6, so all we need to find is the height, h. By using the Pythagorean theorem, we can see that the height is [tex]10^{2} - 6^{2} = \sqrt{64}[/tex], or 8. Plugging in all the values into the formula gives us:
V = [tex]\frac{1}{3} \pi (6)(8)[/tex]

Imani sells shirts packed in boxes that are each 15in. x 10in. x 2in. Imani stacked 3 boxes and wrapped them with one piece of paper. How much paper did she use, not including overlap?
Answer:
She used 600 square inches of paper.
Step-by-step explanation:
Since the box are 15 in x 10 in x 2 in and are stacked on top of each other, they form a bigger rectangular prism with 15 in x 10 in x 6 in. In order to calculate how much paper she used, we need to calculate the surface area of this prism, this is done by using the following formulla:
surface area = 2*width*length + 2*width*height + 2*length*height
surface area = 2*15*10 + 2*15*6 + 2*10*6 = 300 + 180 + 120
surface area = 600 in².
She used 600 square inches of paper.
