Table B and C

In Table B, the X coordinate of -3 has two different answers which is impossible in a function because it only has one output or one answer which is y.

In Table C, the X coordinate of 0 also has two different outputs or two different answers, and with a function, there is only one y coordinate for each X coordinate.

The problem states that a can of tomato sauce contains 8 oz of sauce and a case contains 12 cans. We are trying to find out how many cases of tomato sauce Chef Hugo orders and we know that he gets a total of 480 oz of sauce.

What in mathematics is a linear equation?

According to Wolfram MathWorld A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

We can use the formula 12(8)x = 480 to find out the number of cases of tomato sauce that Chef Hugo orders.

Here's the calculation:

12(8)x = 480

96x = 480

x = 5

Therefore, Chef Hugo orders 5 cases of tomato sauce.

y equals the quantity negative 3 times x plus 7 end quantity over 4.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given a linear equation in two variables.

3x+ 4y = 7

We have to find an expression to calculate y from the equation.

Subtracting both sides of the equation with 3x, we get,

3x + 4y - 3x = 7 - 3x

4y = 7 - 3x

Dividing throughout by 4,

4y/4 = (7 - 3x)/4

y = (7 - 3x) / 4

Hence the value of y is the quantity negative 3 times x plus 7 end quantity over 4.

A vertical asymptote exists of the form x = k where y→∞ or y→ -∞.

A slant asymptote exists of the form y = mx + b where m ≠ 0.

Vertical lines go up and down and are in the form of x = a, where a stands for the common x-coordinate of all locations, whereas horizontal lines go left to right and take the shape of y = b, where b stands for the y-intercept.

A vertical line that directs the function's graph but is not actually a part of it is called a vertical asymptote. Because it appears at an x-value outside of the function's domain, the graph can never cross it. There may be multiple vertical asymptotes for a given function. All common factors are cancelled in the denominator, D(x).

A horizontal asymptote exists of the form y = k where x→∞ or x→ -∞ if the value of the one/both of the limits lim ₓ→∞ f(x) and lim ₓ→ -∞ f(x).

Answer:

(5,4)

Step-by-step explanation:

first, if you have a calculator you can put the equation into y = and just find the maximum point there

to find the x value of the maximum point you do -B/2A

-80/2(8) = 5 so the x value would be 5

then to find y just plug in 5 for x and you should get 4

Answer:

Maximum value of
[tex]f(x) = - 8x^2 + 80x - 196[/tex]

is

[tex]\boxed{f(x) = 4}[/tex]

Step-by-step explanation:

The maximum or minimum value of a function f(x) occurs when the first derivative equals zero

The first derivative of
[tex]f(x) = - 8x^2 + 80x - 196[/tex]

[tex]f'(x) = \dfrac{d}{dx}\left(-8x^2+80x-196\right)[/tex]

[tex]=-\dfrac{d}{dx}\left(8x^2\right)+\dfrac{d}{dx}\left(80x\right)-\dfrac{d}{dx}\left(196\right)[/tex]

[tex]\dfrac{d}{dx}\left(8x^2\right) = 16x\\\\=- \dfrac{d}{dx}\left(8x^2\right) = -16x\\\\\\\dfrac{d}{dx}\left(80x\right)=80\\\\\dfrac{d}{dx}\left(196\right)=0[/tex]

[tex]\dfrac{d}{dx}\left(-8x^2+80x-196\right) \\\\\\ =-16x + 80 + 0\\\\= -16x + 80\\\\[/tex]

Set this expression equal to 0 and solve for x to find the x value which maximizes or minimizes the function

[tex]-16x + 80 = 0\\\\\implies -16x = -80\\\\x = -80/-16\\\\x = 5\\\\[/tex]

Plug this value of x into the original function to get the maximum or minimum value.

[tex]f(5) = -8(5^2) + 80(5) - 196\\\\= -8 (25) +400 -196\\\\= -200 + 400 - 196\\\\= 4\\\\[/tex]

So the maximum value of [tex]\boxed{f(x) = 4}[/tex] ANS

and occurs at [tex]x = 5[/tex]  

(Strictly speaking to find if this is a maximum or minimum, we have to find the second derivative and see if it is negative or positive. If negative, it is a maximum, if positive it is a minimum

But since the question does not ask for this, I am skipping it. In case you are interested, the second derivative of f(x) is the derivative of f'(x) which will work out to -16 so it is a maximum)

A chord is the line segment that the two points determine, i.e., the interval on the secant with the two points as its ends.

In the plane, a circle is created by each point that is a specific distance from another point (center). Therefore, it is a curve made up of points that are spaced out from one another in the plane in a fixed manner. It rotates symmetrically around the center at all angles. Every pair of points in the plane of a circle, which is a closed two-dimensional object, are evenly distanced from the "center." Specular symmetry is produced by a line that traverses the circle.

The value of h in terms of x when the volume of cylinder is equal to that of cone is h = 6x²

Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface. The unit of volume is in cubic units such as m3, cm3, in3 etc. Sometimes, volume is also termed capacity.

The volume of a cone is linked to the volume of a cylinder. A cone is one third of the volume of a cylinder. The volume of a cone is ¹/₃ × π × r² × l. To calculate the volume we multiply these values together.

The volume of cylinder = πr²h

and volume of cone = 1/3 πr²h

since the volume of the cone and cylinder are equal

πr²h = 1/3 πr²h

r in cylinder = x cm and h is 2x

r in cone = x cm

therefore πx²×2x = 1/3πxh

divide both side by πx

π2x³/πx = h/3

2x² = h/3

therefore h = 3×2x²

h = 6x²

Answer:

2.1

Step-by-step explanation:

σ total ^ 2 = σ randi ^2 + σ leah ^2 = 1.1^2 + 1.8^2 = 4.45

σ total = √4.45 = 2.1

Randi and Leah can expect the total number of hours spent studying to vary by approximately 2.1 hours from the mean.

The correct option is C.

The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean.

Given:

Randi and Leah are studying together for an exam.

Let X represent the number of hours Randi spends studying nightly, and let y represent the number of hours Leah spends studying nightly.

The mean of X is 4.5 hours with a standard deviation of 1.1 hours, and the mean of Y is 3.7 hours with a standard deviation of 1.8 hours.

Assuming these are independent random variables,

S = X + Y

σ²  = σ²(Randi)² + σ²(Leah)

    = (1.1)² + (1.8)²

    =√(4.45)

σ  = 2.1

Therefore, the sum is 2.1.

The measure of the angle ∠B of the triangle ABC will be 27°.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

In ∆ABC, if m∠A is seven more than four times m∠B and m∠C is eleven more than m∠B. Then the equations are given as,

∠A = 4∠B + 7                                ...1

∠C = ∠B + 11                                ...2

∠A + ∠B + ∠C = 180°                   ...3

From equations 1, 2, and 3, then we have

4∠B + 7° + ∠B + ∠B + 11° = 180°

5t - 3 + 3 = 3t - 5 + 3

5t = 3t - 2

Then subtract 3t from both sides:

5t - 3t = 3t -2 - 3t

2t = -2

Finally, divide both sides by 2 to solve for t:
