Answers

Answer 1

All options except Option D , a² + b²  , is the square of the binomial.

What is a Binomial ?

A polynomial that contains only two term is called a Binomial.

The sum of square of a binomial is the sum of square of the first term , square of second term and twice of the product of the first and second term.

(a+b)² = a² +b² +2ab

(a-b)² =  a² +b²-2ab

The options have to be broken down into this form to check whether they are square of a binomial

Option A : 4m² - 6mn + 9n² = (2m -3n)²

Option B:  16x² + 24xy + 9y²=(4x+3y)²

Option C : c²- 2cd - d²=(c-d)²

Option D : a² + b² cannot be written as the square of binomial.

All options except Option D is the square of the binomial.

The radius of a spherical balloon a is increasing at a constant rate of 0.1 cm/s. another balloon, b, is being continuously deflated in such a way that the total volume of a and b remains constant. suppose that at the beginning the radius of a is 10 cm and that of b is 9 cm. find the rate of change of the radius of b when the radius of a is 12 cm

Answers

Let [tex]r_A[/tex] and [tex]r_B[/tex] be the respective radii of balloons A and B. If the fixed total volume is V, then

[tex]V = \dfrac{4\pi}3\left({r_A}^3 + {r_B}^3\right)[/tex]

and knowing [tex]r_A=10\,\rm cm[/tex] and [tex]r_B=9\,\rm cm[/tex] at the start, we have V = 6916π/3 cm³. Then when [tex]r_A=12\,\rm cm[/tex], the radius of the other sphere is [tex]r_B=1\,\rm cm[/tex].

Differentiating both sides with respect to time t gives a relation between the rates of change of the radii:

[tex]0 = 4\pi \left({r_A}^2 \dfrac{dr_A}{dt} + {r_B}^2 \dfrac{dr_B}{dt}\right) \implies \dfrac{dr_B}{dt} = -\left(\dfrac{r_A}{r_B}\right)^2 \dfrac{dr_A}{dt}[/tex]

We're given [tex]\frac{dr_A}{dt} = 0.1\frac{\rm cm}{\rm s}[/tex] the whole time. At the moment [tex]r_A=12\,\rm cm[/tex], the radius of balloon B is changing at a rate of

[tex]\dfrac{dr_B}{dt} = -\left(\dfrac{12\,\rm cm}{1\,\rm cm}\right)^2 \left(0.1\dfrac{\rm cm}{\rm s}\right) = \boxed{-14.4 \dfrac{\rm cm}{\rm s}}[/tex]

A median is:

In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value. The basic feature of the median in describing data compared to the mean is that it is not skewed by a small proportion of extremely large or small values, and therefore provides a better representation of a "typical" value. Median income, for example, may be a better way to suggest what a "typical" income is, because income distribution can be very skewed. The median is of central importance in robust statistics, as it is the most resistant statistic, having a breakdown point of 50%: so long as no more than half the data are contaminated, the median is not an arbitrarily large or small result.

Given that:-

There are two containers out of which one can hold 31/2 liters of oil while the other can hold 22/3 liters of oil. Suppose there are 4 containers of the first type and 9 containers of the second type.

The volume of oil in the first container is [tex]\dfrac{31}{2}[/tex] liters so for four containers the volume will be:-

V = 4 x  [tex]\dfrac{31}{2}[/tex]

V = 2 x 31 = 62 liters

The volume of oil in the second container is [tex]\dfrac{22}{3}[/tex] liters.

V = 9 x  [tex]\dfrac{22}{3}[/tex]

V = 3 x 22 = 66 liters

•function notation•

does anyone know how to do this. please help.

Answers

Answer:

f(3) = 16

Step-by-step explanation:

Function notation is used to express a rule in terms of x and f(x), where x is independent and f(x) is dependent.

Pronunciation of Function Notation

To use function notation it is important to know how to express the function in words.

The function "f(x) = 3x + 7" would be pronounced "F of X equals three X plus 7."

So, the function is "F of" whatever variable or value is within the parentheses.

Use of Function Notation

The function y=x is similar to the function f(x)=x. As a matter of fact, when graphed they both work the same way, but the function notation seen in the question allows us to see the value of x.

This is because the value in the parentheses is the value of x. So, in this situation, the question asks what is the value of the function when x equals 3.

Solving for f(3)

To solve this function, all we have to do is plug 3 in for x and evaluate.

f(3) = 3(3) + 7

First, multiple 3*3

f(3) = 9 + 7

Next, add 7

f(3) = 16

Since the object is a sphere in a cylinder, we need to know the volume of sphere and cylinder.

What is volume of a cylinder?

The volume of a cylinder is given by V '= πr²h where

r = radius of cylinder and h = height of cylinder.

Since the height of the cylinder equals the diameter of the sphere, h = 2r

So, V' = πr²h

V' = πr² × 2r

An annuity is a fixed payment of money over a specified period of time.

The formula for determining the future value of the annuity is: yearly deposit x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

r = interest rate = 3.5%n = number of years = 18 - 12 = 6

Future value of the annuity: $100 x [{(1.035^6) - 1} / 0.035}  = $655.02

The number that could not be a value of y if y = 4x² - 6 is -12.

What is the value of y for a function of f(x)?

The value of y for which a function f(x) = y = 4x² - 6 can be determined by knowing the smallest value of y for which x is equal to zero.

So, from the equation y = 4x² - 6, we will replace the value of x with zero to determine the smallest value of y.

i.e.

y = 4(0) - 6

y = 0 - 6

y = -6

Thus, any number smaller than -6 could not be a value of y for the equation y = 4x² - 6.

Therefore, we can conclude that the number that could not be a value of y if y = 4x² - 6 is -12.

So, I would plot a new graph to answer this question.

The systems of inequalities are given as:

x + y ≥ -3 and 5x – y ≤ -3

2x – y ≤ -1 and x + 2y < 4

4x – 3y < 12 and x + 3y ≥ 6

Next, we plot these inequalities on a graph and write out the points of intersection.

From the attached graph, we have:

y − x > 1 and 2x + y ≤ 2  ⇒ (0.3, 1.3)

x + y ≥ -3 and 5x – y ≤ -3  ⇒ (-1, -2)

2x – y ≤ -1 and x + 2y < 4  ⇒ (0.4, 1.8)

4x – 3y < 12 and x + 3y ≥ 6 ⇒ (3.6, 0.8)

Hence, the solutions to the systems of inequalities are (0.3, 1.3), (-1, -2), (0.4, 1.8) and (3.6, 0.8)
