Answers
Option (4) all real numbers greater than or equal to -3
Step-by-step explanation:
Domain: Domain of function is defined by the x-values (Input values) on the graph.
Range: Range of a function is defined by the y-values (output values) on the graph.
x-values are starting from (-3) to infinity.
Therefore, domain of the function will be all real numbers greater than equal to (-3). Option (4) will be the answer.
The domain of the function are all real numbers greater than or equal to -3.
What is function?A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given is a graph, we need to find domain of the function on the graph,
Domain is the set of all possible inputs or x-values, for which the given function is defined.
The given graph is defined form -3 to positive infinity. The point -3 included in the set of input because there is a closed circle at x=-3.
So, domain of the function are all real numbers greater than or equal to –3.
Hence, the domain of the function are all real numbers greater than or equal to -3.

)The diameter of a cylinder is 7 yards. The height
is 12 yards. What is the volume, in terms of T and
to the nearest cubic yard, of the cylinder?
Answers
Answer: 462 yards ^3
Step-by-step explanation:
The equation for the volume of a cylinder is πr^2h
the diameter is 7 yards and the radius is just half the diameter so the radius is 3.5
the height is 12 yards
so π(3.5)^2(12) = 461.814120078 yards ^3

Virgil opened an account with a deposit of $815.
. The bank pays 5% interest compounded annually on this account.
• Virgil makes no additional deposits or withdrawals.
How much interest will the account have earned after 6.5 years?
Answers
Answer:
$304.15
Step-by-step explanation:
The amount of interest earned can be found from the formula ...
I = P((1 +r)^t -1)
I = $815((1 +0.05)^6.5 -1) ≈ $815(0.373189) ≈ $304.15
Virgil's account will have earned about $304.15 in interest in 6.5 years.

Using correlation coefficients, it is found that the value of r is greater than 0 and close to 1, as the scatter-plot is increasing linearly.
What is a correlation coefficient?It is an index that measures correlation between two variables, assuming values between -1 and 1.If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.Researching the problem on the internet, it is found that the relation is modeled by an increasing scatter-plot, hence r > 0. There are very few points in which there are oscillations, which indicate a strong relationship, hence r is closer to 1.

You need 2 coordinates from your graph as long as the line you have is completely straight. You have 2 points it is (0,3) & (8,0)
So your y2 is 0
y1 is 3
So your x2 is 8
x1 is 0
Plug in and solve (keep in mind you should be expecting a negative slope since your line is sloping downwards as you advance to the right.
m = (0-3)/(8-0)
m = -3/8
m = slope = -3/8x = -0.375x

Three 3-digit numbers are formed using the digits 1 through 9 exactly once each. The hundreds digit of the first number is 1. The tens digit of the second number is 8. The units digit of the third number is 5. The ratio of the first number to the second number to the third number is 1:3:5, respectively. What is the sum of the three numbers?
Answers
Answer:
1161
Step-by-step explanation:
We can solve this using what we know about multiples of 3 and 5. Multiplying the first number by 3 will give the value ...
1?? × 3 = 38? . . . . where ? is an unknown digit
The two least significant digits in the first number must be ones that give 80-something when multiplied by 3. They will be between 80/3 = 26 2/3 and 90/3 = 30. The requirement that the least significant digit be odd* means the choices are 27 or 29.
When the first number is 127, its triple is 381. The 1 in the least significant digit is disallowed by the requirement that the 9 digits of these numbers be unique. (127 already has 1 as its most-significant digit.)
So, the first number is 129, making the second number be 3×129 = 387, and the third number be 5×129 = 645.
The numbers have the ratios ...
129 : 387 : 645 = 1 : 3 : 5 . . . . . . . as required.
We note that the digits 1–9 are used exactly once each, as required.
The sum of the numbers is 1161.
_____
* Only odd numbers will give a product that ends in 5 when they are multiplied by 5. The requirement that the third number have a ones digit of 5 means the ones digit of the first number must be odd.

Squares are such bases that multiply itself two times.
⇒ (3p⁴ + 2q⁴)(3p⁴ + 2q⁴)
Simplifying the expression using (a + b)(a + b) = (a x a) + (ab) + (ab) + (b²)
⇒ (9p⁸ + 6p⁴q⁴ + 6p⁴q⁴ + 4q⁸)

Mark sold 2 7/8 gallons of lemonade.
Regan sold 2/3 as much lemonade as Mark.
The following steps can be used in order to determine the total amount of lemonade Regan sells:
Step 1 - The arithmetic operations can be used in order to determine the total amount of lemonade Regan sells.
Step 2 - According to the given data, Mark sold 23/8 gallons of lemonade.
Step 3 - Let the total amount of lemonade Regan sells be 'x'.
Step 4 - So, the value of 'x' can be calculated as:
x = 23/8 × 3/2
x = 63/16
The total amount of lemonade Regan sells is 69/16 gallons.
