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.

If $450.46 were invested at 2% interest that is compounded annually, it would be worth after 6 years.

The future value of a loan or investment may be determined using the formula FV = P*(1+R/N)(N*T), where FV is the future value, P is the original principal, R is the annual interest rate, N is the number of times interest is compounded annually, and T is the amount of time in years.

A = P(1+r/n)ⁿ

From the question, we have

P = $400

t = 6 year

r = 2%

r = 0.02

n = 1

A = P(1+r/n)ⁿ

A = 400(1+0.02/1)⁶

Now,

[tex]AB = \left[\begin{array}{ccc}2&3\\-1&1\end{array}\right] \left[\begin{array}{ccc}1&9\\-3&k\end{array}\right] = \left[\begin{array}{ccc}-7&18+3k\\2&-9-k\end{array}\right][/tex]

Thus, in order for AB = BA, we must have that

[tex]\left[\begin{array}{ccc}-7&18+3k\\2&-9-k\end{array}\right] = \left[\begin{array}{ccc}-7&-6\\-6-k&-9-k\end{array}\right][/tex]

If 29 student tickets were sold, then all possible values for the number of adult tickets that the drama club must sell in order to meet the show's expenses are 54 and 55 .

the price for each student ticket is $4.50 and adult is $8 ;

The number of people auditorium can hold is = no more than 84 people ;

the number of children tickets sold is = 29 tickets ;

Let "x" be number of adult tickets sold.

The total revenue from ticket sales = $4.50×29 + $8×(x)

⇒ $130.5 + $8x.

The total revenue must be at least $560,

So , $130.5 + $8x ≥ $560.

Subtracting $130.5 from both sides, we get $8x ≥ $429.5   ;

Dividing both sides by 8, we get x ≥ 53.69    ;

Since the number of adult tickets sold must be an integer, the minimum number of adult tickets that must be sold is 54.

The maximum number of people allowed in the auditorium is 84, so the maximum number of adult tickets that can be sold is 84 - 29 = 55.

Therefore, the possible values for the number of adult tickets that must be sold are 54, 55.

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.

So, the formula for finding the perimeter of a triangular prism is:

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 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 angle of depression from the top of the cliff to the edge of the water

is 54.46°.

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°

Hence angle of depression is 54.46°.

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. So, the simplified expression is:
