Y= f(x) 16x find f(x) when x= 1/2
The value of f(x) when x = 1/2 is 8.
Explanation:To find the value of f(x) when x = 1/2, we need to substitute x = 1/2 into the equation y = f(x) = 16x.
Substituting x = 1/2, we get y = f(1/2) = 16(1/2) = 8.
Therefore, f(1/2) = 8.

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
TDC, Inc.'s net profits were $-2000 each month last year.
Let x be the net profit for the year
As we know there are 12 months in 1 year.
So the net profit:
x = $-2000×12
x = -$24,000
Thus, the TDC's net profits for the year were -$24,000 if TDC, Inc. net profits were $-2000 each month last year option (A) is correct.

X^2+12x-13=0
To solve the quadratic equation x^2 + 12x - 13 = 0 by completing the square, follow these steps. The solutions to the equation are x = 1 or x = -13.
Explanation:To solve the quadratic equation x^2 + 12x - 13 = 0 by completing the square, follow these steps:
Move the constant term to the other side of the equation:x^2 + 12x = 13Take half of the coefficient of the x-term and square it:(12/2)^2 = 36Add this value to both sides of the equation:x^2 + 12x + 36 = 13 + 36Factor the left side of the equation, which should be a perfect square:(x + 6)^2 = 49Take the square root of both sides and solve for x:x + 6 = ±√49x + 6 = ±7x = -6 ± 7Therefore, the solutions to the equation are x = 1 or x = -13.The price of grapes at the grocery store is $1.44 per pound. There are approximately 0.45 kilograms in a pound. To the nearest cent, what is the price of grapes in dollars per kilogram?
1 lb / 0.45 = 2.22
so approximately 2.22 kilograms per pound
divide price per pound by kilometers per pound
1.44 / 2.22 = 0.648
round to 0.65, so it costs $0.65 per kilogram
Answer:
1 lb / 0.45 = 2.22
so approximately 2.22 kilograms per pound
divide price per pound by kilometers per pound
1.44 / 2.22 = 0.648
round to 0.65, so it costs $0.65 per kilogram

how can you use a number to explain what an integer and rational number are??
The terms even and odd only apply to integers; 2.5 is neither even nor odd. Zero, on the other hand, is even since it is 2 times some integer: it's 2 times 0. To check whether a number is odd, see whether it's one more than some even number: 7 is odd since it's one more than 6, which is even.
Another way to say this is that zero is even since it can be written in the form 2*n, where n is an integer. Odd numbers can be written in the form 2*n + 1. Again, this lets us talk about whether negative numbers are even and odd: -9 is odd since it's one more than -10,which is even.

Two radical expressions with the same degree and the same _____ are called like terms.
Answer:
Two radical expressions with the same degree and the same radicand are called like terms.
Step-by-step explanation:
All the terms that have same power and vari ables are called like terms.
For example: 3x²y and 5x²y are like terms, 2x³ and 7x³ are like terms, etc.
The number under the root is known as radicand.
Two radical expressions are like terms if
1. They have same degree.
2. They have same radicand.
Therefore the two radical expressions with the same degree and the same radicand are called like terms.
Two radical expressions are called like terms if they have the same degree and the same:
E. radicand
Two radical expressions are called like terms if they have the same degree and the same radicand. The radicand is the number or expression inside the radical symbol. For example, in the radical expression [tex]\(\sqrt{5}\)[/tex], the radicand is 5. For two radical expressions to be like terms, they must not only have the same index (degree) of the radical but also the same radicand.
Consider the expressions [tex]\(\sqrt{3}\) and \(2\sqrt{3}\)[/tex]. These are like terms because they both have the same degree (square root, which is an index of 2) and the same radicand (3). Similarly, [tex]\(\sqrt[3]{7}\) and \(4\sqrt[3]{7}\)[/tex] are like terms because both are cube roots with a radicand of 7.
However, [tex]\(\sqrt{2}\) and \(\sqrt{3}\)[/tex] are not like terms because their radicands differ. Likewise, [tex]\(\sqrt[4]{5}\) and \(\sqrt{5}\)[/tex] are not like terms because their degrees (indices) differ. Therefore, for radical expressions to be like terms, matching radicands and degrees are essential.
The correct question is:
Two radical expressions are called like terms if they have the same degree and the same
A. denominator
B. radical
C. term
D. number

John and 3 friends are going out for pizza for lunch. They split one pizza and 4 large drinks. The pizza cost $13.00. After using a $6.00 gift certificate, they spend a total of $13.20. Write an equation to model this situation, and find the cost of one large drink. a. 3d + $13.00 – $6.00 = $13.20; $2.07 b. 4d + $13.00 – $6.00 = $13.20; $1.55 c. 4d – $13.00 + $6.00 = $13.20; $6.73 d. 4d + $13.00 – $6.00 = $13.20; $1.60
4d +13.00 -6.00 = 13.20

What is 16% of 43 minutes
Answer:
16% of 43 minutes are 6.8 minutes.
Step-by-step explanation:
To know the percentage of a quantity first you should divide the percentage by a hundred, then you should multiply the quantities, as follows.
1. Calculate the percentage:
[tex]\frac{16}{100}=0.16[/tex]
2. Multiply the percentage by the quantity:
[tex]0.16*43=6.88[/tex]
Therefore 16% of 43 minutes are 6.8 minutes.

The quotient of a number and 4, minus 1, equals 5/4. find the number
Final answer:
The equation (x / 4) - 1 = 5/4 is solved by isolating x and simplifying, which reveals that the number sought is 9.
Explanation:
To solve the equation where the quotient of a number and 4, minus 1, equals 5/4, we can set up the following algebraic expression:
Let x = the number we want to find.
Now, we translate the problem into an equation:
(x / 4) - 1 = 5/4
To find the value of x, follow these steps:
Add 1 to both sides of the equation to get the fraction by itself:
(x / 4) - 1 + 1 = 5/4 + 1
Simplify both sides:
(x / 4) = 5/4 + 4/4
Add the fractions on the right side:
(x / 4) = 9/4
Multiply both sides of the equation by 4 to solve for x:
4 * (x / 4) = 4 * (9/4)
Simplify both sides:
x = 9
Therefore, the number we are looking for is 9.
the greatest wind speed ever recorded on earth's surface is 231 miles per hour. what is the speed in kilometers per hour
To convert 231 miles per hour to kilometers per hour, multiply by the conversion factor of 1.60934, resulting in approximately 371.76 km/h.
The greatest wind speed ever recorded on Earth's surface is 231 miles per hour (mph). To convert this speed into kilometers per hour (km/h), we use the conversion factor that 1 mile is approximately 1.60934 kilometers. Therefore, the speed in kilometers per hour is given by multiplying the speed in miles per hour by this conversion factor.
Here is the calculation:
231 mph x 1.60934 = 371.75774 km/h.
Approximately, the wind speed would be 371.76 km/h after converting from miles per hour.

What is 7 feet converted to miles?
Answer:
Step-by-step explanation:
Use the factor-label method you learned in chemistry (also known as dimensional analysis), keeping in mind 2 things:
the label you want needs to be on the top of the equivalent ratio, and
that there are 5280 feet in 1 mile. Having said that:
[tex]7feet*\frac{1mile}{5280 feet}=[/tex]
The math tells us to divide 7 by 5280. That means that
7 feet = .0013257576 miles, to however many decimal places you need. That 7575 is repeating, btw.

What is a quadrilateral?A quadrilateral is a shape made up of four sides having the sum of the angles 360 degrees. The given shape is like a parallelogram in which two sides are equal and at the same angles.
Given that angle A in the quadrilateral is 85 degrees. The value of the angle B will be calculated as:-
∠A + ∠B +∠C + ∠D = 360
85 + ∠B + 85 + ∠B = 360 ∠B = ∠D
170 + 2∠B = 360
2∠B = 360 - 170
2∠B = 190
∠B = 190 / 2
∠B = 95
Therefore, the measure of the angle ∠ABC will be 95 degrees.
