Which one of the following functions is non-linear?

Ten percent of the 30 team members which means that  [tex]$\dfrac{10}{100} \cdot 30 = 3$[/tex]  team members are new to the team. So, the answer is 6 new team members. Option D is correct.

To understand how we got the answer, we need to understand the concept of "percentage". The percentage is a way of showing a number as a fraction of 100. So, 10% means  [tex]$\dfrac{10}{100}$[/tex].

Now, if we multiply this fraction by the total no. of team members, we'll find the no. of new team members.

[tex]$\dfrac{10}{100} \cdot 30 = 3$[/tex]

So, 10% of the 30 team members are equal to 3 team members, and that's why the answer is D-6.

Answer:

Step-by-step explanation:

You would need 100 ounces of apples to get 100% of your daily vitamin C.

We know that 8 ounces of apples contains 8% of your daily vitamin C.

To find out how many ounces of apples are needed to get 100% of your daily vitamin C, we can use the following proportion:

(8 ounces / 8%) = (x ounces / 100%)

where x represents the number of ounces needed for 100% of the daily vitamin C.

To solve for x, we can cross-multiply and divide:

8 ounces * 100% = 8% * x ounces

8 ounces * 100 = 8 * x ounces

800 = 8x

x = 100

Therefore, you would need 100 ounces of apples to get 100% of your daily vitamin C.

The temperature during the afternoon in Chicago is 2°F

What is meant by the temperature of a place?

The average air temperature throughout a specific time period, typically a day, a month, or a year, as measured by a thermometer that has been properly exposed determines the temperature of a place.

Given,

 The overnight temperature in Chicago =  -7°F

The temperature that had risen during the afternoon = 9°F

From this data, we can see that there is no temperature change during the morning in Chicago.

That means the temperature remained constant throughout the night till the next morning.

Therefore the temperature during the afternoon in Chicago = -7+9 = 2°F.

The scalars 0 and any scalar with magnitude 0 satisfy the equation 4(2−5)(4,4) = 0 for every pair of vectors (4,4).

Vectors are mathematical objects that have both magnitude and direction. They can be multiplied by scalars, which are non-zero real numbers.

In this case, we are looking for non-zero scalars that satisfy the equation 4(2−5)(4,4)=0 for every pair of vectors (4,4).

To begin, we simplify the equation.

The expression 2−5 equals to -3, so

=> 4(-3)(4,4) = 4(-12,-12).

Next, we multiply 4 by -12 to get -48. The expression

=> 4(-12,-12) = (-48,-48).

Now, we need to find non-zero scalars that multiply (-48,-48) to give us a zero vector, which is a vector with magnitude of 0 and direction undefined.

Any scalar that satisfies this condition is a solution. For example, the scalar 0 satisfies this condition because

=> 0 * (-48,-48) = (0,0).

Additionally, any scalar with magnitude 0 will also satisfy this condition because the product of a vector and a scalar with magnitude 0 is always the zero vector.

The process of converting a hexadecimal value to octal involves two steps: first converting the hexadecimal value to binary, and then converting the binary value to octal.

Hexadecimal is a number system that uses 16 digits, from 0 to 9 and A to F, to represent values. It is commonly used in computer science, as it provides a concise representation of binary data.

To convert a hexadecimal value to an octal value, the hexadecimal number must first be converted to binary, and then the binary number must be converted to octal.

The octal number system uses 8 digits, 0 to 7, to represent values. To convert a binary number to octal, the binary number is split into groups of 3 bits each, starting from the rightmost bit.

The value of each group is then found by adding up the values of the bits that are turned on.

In this case, the unsigned hexadecimal value is given, and we need to find its unsigned octal equivalent.

To do this, we first convert the hexadecimal value to binary. We then group the binary digits into groups of 3 bits each and find the octal equivalent of each group.

The final answer is the concatenation of the octal values of each group, from left to right.

Trigonometric functions, often known as circular functions, are, in a nutshell, the functions of the angle of a triangle. This indicates that the relationship between a triangle's angles and sides is provided by these trig functions. The basic trigonometric functions are sine, cosine, tangent, cotangent, secant, and cosecant.

Given the height of the cliff = 70 feet,

the lake water reaches 50 ft away from the cliff.

distance from the base of the cliff to lake water = 50 feet

the angle of depression is found by tanФ

where Ф = angle of depression

tanФ = perpendicular/base

perpendicular = height = 70 feet

base= 50 feet

tanФ = 70/50

Ф = tan⁻¹(1.4)

Ф = 54.46°

To find the perimeter of a triangular prism, you need to add up the lengths of all three sides of the triangular base and all three sides of the rectangular lateral faces.

The formula for the perimeter of a triangular prism is P = a + b + c + 3l, where a, b, and c are the lengths of the sides of the triangular base, and l is the length of each of the rectangular lateral faces.

The perimeter of the triangular prism is solved

A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.

The volume of a prism is the product of its base area and height

Volume of Prism = B x h

where B = base area of prism

h = height of prism

Given data ,

To find the perimeter of a triangular prism, you need to add the lengths of all the edges. The edges of a triangular prism include the three sides of the base triangle and three additional edges connecting the corresponding vertices of the two base triangles.

The stated combination of coins is not possible as the number of quarters are highly more than the number of dimes and nickels.

Let the number of dimes be x. So, the number of an nickels will be 2x. The number of quarters will be (30 - 3x). As per the known information, the one nickel is 0.05 dollars, one dime is 0.1 dollars and one quarter is with 0.25 dollars.

Now forming the expression -

x×0.1 + 2x×0.05 + (30-3x)×0.25 = 3

Performing multiplication on Left Hand Side of the equation

Absolute value of expression | 6 - 10 | can be simplified into 4.

The absolute value of a number is its distance from zero on the number line, regardless of its sign. It is represented by enclosing the number inside two vertical bars (| |) and is always a non-negative number.

In mathematical terms, the absolute value of x is defined as:

|x| =

a) x if x >= 0

b) -x if x < 0

So, for any number x, its absolute value is always positive or zero.

The expression |6 - 10| represents the absolute value of the difference between 6 and 10. To find the absolute value, we need to consider only the magnitude of the result and ignore its sign. In this case, the difference between 6 and 10 is -4, which is a negative number. Therefore, to find the absolute value, we need to take the absolute value of -4, which is 4.

Coefficient of determination R²

The percentage of variance in the dependent variable that is explained by the independent variable is shown by the coefficient of determination.  R² value is always in the range between 0 and 1. As opposed to 1, which shows that the independent variable fully explains the variation in the dependent variable, 0 means that the independent variable is utterly ineffective at predicting the variance in the dependent variable.

The conversions are 0.261 kg, 300000 seconds, 947.4 cm and 730 L.

a. 261 g to kg

For converting grams to kg, we divide by 1000.

(261 / 1000)= 0.261 kg

The number of significant figures in 261 g is 3 and the number of significant figures in the answer 0.261 kg is also 3.

b. 3 days to seconds

1 day = 24 hours, 1 hour = 60 minutes, 1 minute = 60 seconds

1 day = 24 x 60 x 60 seconds

Therefore, 3 days = 3 x 24 x 60 x 60 seconds = 2, 59, 200 seconds

Since, the number of significant figures in 3 days is 1, hence we write 2, 59, 200 as 300000 seconds, such that it has 1 significant figure.

c. 9, 474 mm  to cm

For converting mm to cm, we divide by 10

(9474 / 10) = 947.4 cm

The number of significant figures in 9, 474 mm is 4 and the number of significant figures in the answer 947.4 cm is also 4.

d. 0.73 KL to L

1 KL = 1000 L

0.73 KL = 0.73 X 1000 L = 730 L
