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

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.

The value of cos E is [tex]\frac{24}{25}[/tex]. The correct option is A. [tex]\frac{24}{25}[/tex]

From the question, we are to determine the value of cos E

From the given information, we have

[tex]sin \ D=\frac{24}{25}[/tex]

By SOH CAH TOA

Opposite = 24

Hypotenuse = 25

Thus, considering the diagram

/EF/ = 24

and

/DE/ = 25

By SOH CAH TOA

[tex]cos \ E =\frac{/EF/}{/DE/}[/tex]

∴ [tex]cos \ E =\frac{24}{25}[/tex]

Hence, the value of cos E is [tex]\frac{24}{25}[/tex]. The correct option is A. [tex]\frac{24}{25}[/tex]

Answer:

$320

Step-by-step explanation:

1. 3x + 4x = 560 (since they are ratios, x would be the same amount)

2. 7x = 560

3. x = 80

This means that 3 and 4 should be multiplied by 80 to get the $ amount. The amounts are $240 (3*80) and $320 (4*80).

So, the larger amount if $320.

The volume of the oil required to fill both containers will be 128 liters.

Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width, and height of cube or cubied.

Given that:-

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

So total volume of oil will be calculated as:-

Total volume = 66 + 62 = 128 liters

Therefore the volume of the oil required to fill both containers will be 128 liters.

f(3) = 16

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.

First, multiple 3*3

Next, add 7

The median of this set is:

9

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.

The future value of the annuity on Jennifer’s 18th birthday is $655.02

The interest earned is $55.02.

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:

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

Interest earned =  future value - total amount deposited

655.02 - (100 x 6)= $55.02

y − x > 1 and 2x + y ≤ 2

x + y ≥ -3 and 5x – y ≤ -3

2x – y ≤ -1 and x + 2y < 4

4x – 3y < 12 and x + 3y ≥ 6

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)

We'll need to find the LCM of 5, 8 and 10.

List out the prime factorization of the three numbers.

The unique prime factors are 2 and 5. The '1' isn't a prime number, so we can ignore it.

The '2' has an exponent of 3 as the largest exponent, meaning 2^3 is part of the LCM. The '5' has the largest exponent of 1. So 5^1 = 5 is also part of the LCM

LCM = 2^3*5 = 8*5 = 40

List out the multiples of 40

40, 80, 120, 160, ...

The number 80 is the only multiple between 61 and 107

The volume of the cylinder that is not occupied by the sphere is 2πr³/3

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

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

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

So, V' = πr²h

V' = πr² × 2r

V' = 2πr³

The volume of a sphere of radius r is given by V = 4πr³/3

The volume of the cylinder not occupied by the sphere is V" = V' - V

=  2πr³ - 4πr³/3

= (6πr³ - 4πr³)/3

= 2πr³/3

So, the volume of the cylinder that is not occupied by the sphere is 2πr³/3
