do u have the answer

For this case we have that if the box is cubed, then the volume is given by:

[tex]V = l ^ 3[/tex]

Where:

l: It's the side of the cube

We have to:

[tex]l ^ 3 = 2244\\l = \sqrt [3] {2244}\\l = 13,09204886[/tex]

So, l is the side of the box. The surface area of a cube is given by:

[tex]SA = 6l ^ 2\\SA = 6 * (13.09204886) ^ 2\\SA = 1028.41046012[/tex]

Rounding off we have that the surface area of the cube is:

[tex]1028.4 \ in ^ 2[/tex]

Answer:

[tex]1028.4 \ in ^ 2[/tex]

im not sure but it could be (-2,0) :/

Answer:

(2,0)

The answer is obvious

1. From the given right-triangle, the side opposite to [tex]\theta[/tex] is 6.8 units.

The adjacent side to [tex]\theta[/tex] is 4 units.

Recall the mnemonics, SOH-CAH-TOA.

We use the tangent ratio to obtain:

[tex]\tan \theta=\frac{Opposite}{Adjacent}[/tex]

[tex]\tan \theta=\frac{4}{6.8}[/tex]

[tex]\tan \theta=\frac{10}{17}[/tex]

[tex]\implies \theta=\tan^{-1}(\frac{10}{17})[/tex]

[tex]\implies \theta=30.5\degree[/tex] to the nearest tenth.

2. This time we were given the hypotenuse to be 15.7 units and the adjacent side is 6 units.

We use the cosine ratio to obtain:

[tex]\cos \theta=\frac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos \theta=\frac{6}{15.7}[/tex]

[tex]\cos \theta=\frac{60}{157}[/tex]

[tex]\implies \theta=\cos^{-1}(\frac{60}{157})[/tex]

[tex]\implies \theta=67.5\degree[/tex] to the nearest tenth.

Answer:

25).  55.02°

26).  30.46°

Step-by-step explanation:

Points to remember

Trigonometric ratios

Sin θ  = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = Opposite side/Adjacent side

To find the answer of question 25

Cos θ = Adjacent side/Hypotenuse

 = 9/15.7 = 0.573

θ = Cos⁻¹(0.573) = 55.02°

To find the answer of question 26

Tan θ = Opposite side/Adjacent side

 = 4/6.8 = 0.588

θ = Tan⁻¹(0.588) = 30.46°

I am pretty sure 52 degrees

well, she knows that the mass of chocolate is 1.8 times that of powered sugar.

it just so happen that powered sugar is 100 grams for one cup, and since chocolate is 1.8 times "that", then in one cup of chocolate there must be 1.8 times 100 grams, or 1.8*100 = 180 grams.

the recipe uses 1/2 cup of chocolate, well, half a cup of chocolate, namely half of 180 grams is just 90 grams.

The second graph is the graph of logarithmic function

Logarithmic functions are the inverses of exponential functions. The logarithmic function [tex]y=1og_ax[/tex]is defined to be equivalent to the exponential equation [tex]x=a^y[/tex].

The logarithmic function is similar in shape to the square root function. To graph a logarithmic function it is better to convert the equation to its exponential form.

NUMBER3

Step-by-step explanation:

Table no 3 is representing here a non-linear function.

A nonlinear function, as its name suggests, is a function that is not linear. In other words, the graph of a nonlinear function is not a line, its graph can be anything other than a line

Since a nonlinear function is a function that is not a linear, its equation can be anything that is not of the form f(x) = ax+ b. One examples of nonlinear functions is, f(x) = x2 is nonlinear as it is a quadratic function.

The statement -11 is greater than -3, so it was colder in Milwaukee is true.

Answer:

-11 is greater than -3, so it was colder in Milwaukee.

Step-by-step explanation:

Answer 1 (-11 is greater than -3, so it was colder in Chicago) is incorrect because it was -3 in Chicago, not -11.

Answer 2 (-3 is greater than -11, so it was colder in Chicago) is incorrect because -3 is not greater than -11.

Answer 3 is correct because -11 is greater than -3 and the cities are labeled correctly.

Answer 4 (-3 is greater than -11, so it was colder in Milwaukee) is incorrect because -3 is not greater than -11. Milwaukee was also -11, not -3.

The correct answer is C

EXPLANATION

The given triangle is a right triangle. Since two angles are equal, it is a right isosceles triangle.

This implies that, x=8 units.

Using Pythagoras Theorem,

[tex] {y}^{2} = {8}^{2} + {8}^{2} [/tex]

This implies that:

[tex]{y}^{2} = 64 + 64[/tex]

[tex]{y}^{2} =128[/tex]

Take positive square root,

[tex]{y} = \sqrt{128} [/tex]

[tex]{y} = 8 \sqrt{2} [/tex]

The correct answer is C

Answer:

Correct choice is C. [tex]x=8[/tex], [tex]y=8\sqrt{2}[/tex].

Step-by-step explanation:

Apply formula [tex]\sin\left(\theta\right)=\frac{opposite}{hypotenuse}[/tex]

[tex]\sin\left(45^o\right)=\frac{8}{y}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{8}{y}[/tex]

[tex]y=8\sqrt{2}[/tex]

Apply formula [tex]\tan\left(\theta\right)=\frac{opposite}{adjacent}[/tex]

[tex]\tan\left(45^o\right)=\frac{8}{x}[/tex]

[tex]1=\frac{8}{x}[/tex]

[tex]x=8[/tex]

Hence correct choice is C. [tex]x=8[/tex], [tex]y=8\sqrt{2}[/tex].

Answer:

It is 0

Step-by-step explanation:

Unlike the positive side of the number line which increases its value as it goes up in numbers, the negative side of a number line increases its value as it goes goes down in numbers as the more closer a negative number is to the positive side of infinity, the greater value it has. In this instance, zero is the greater number than -6 and all other negative numbers.

ANSWER

The water arc is 50 ft above the water approximately 42ft and 158ft from the north shore.

EXPLANATION

The water arc is modeled by the function:

[tex]y = - 0.006 {x}^{2} + 1.2x + 10[/tex]

We write this function in vertex form:

[tex]y = - 0.006 ({x}^{2} - 200x )+ 10[/tex]

[tex]y = - 0.006 ({x}^{2} - 200x + ( - 100)^{2} ) - - 0.006( - 100)^{2} + 10[/tex]

[tex]y = - 0.006 ( x- 100)^{2} ) + 60+ 10[/tex]

[tex]y = - 0.006 ( x- 100)^{2} ) +70[/tex]

The vertex of this function is at

(100,70).

This means that the water arc reached a height of 50ft.

We put y=50 and solve for x.

[tex]- 0.006 ( x- 100)^{2}+70 = 50[/tex]

[tex]- 0.006 ( x- 100)^{2} = - 20[/tex]

[tex]( x- 100)^{2} = \frac{10000}{3} [/tex]

[tex]x = 100 \pm \frac{100 \sqrt{3} }{3} [/tex]

x=42.3 or x=157.7

Hence the water arc is 50 ft above the water approximately 42ft and 158ft from the north shore.

The water arc does reach a height of 50 feet, and it is about 42.27 feet and 157.73 feet from the north shore when it is 50 feet above the water.

1.Set up the equation:

[tex]\[ -0.006x^2 + 1.2x + 10 = 50 \][/tex]

2. Simplify the equation:

Subtract 50 from both sides:

[tex]\[ -0.006x^2 + 1.2x + 10 - 50 = 0 \] \[ -0.006x^2 + 1.2x - 40 = 0 \][/tex]

3. Solve the quadratic equation:

We can use the quadratic formula

[tex]\( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \), where \( a = -0.006 \), \( b = 1.2 \), and \( c = -40 \).[/tex]

[tex]\[ a = -0.006, \quad b = 1.2, \quad c = -40 \][/tex]

[tex]\[ \Delta = b^2 - 4ac \] \[ \Delta = 1.2^2 - 4(-0.006)(-40) \] \[ \Delta = 1.44 - 0.96 \] \[ \Delta = 0.48 \][/tex]

[tex]\[ x = \frac{-b \pm \sqrt{\Delta}}{2a} \] \[ x = \frac{-1.2 \pm \sqrt{0.48}}{2(-0.006)} \][/tex]

Calculate the square root of 0.48:

[tex]\[ \sqrt{0.48} \approx 0.6928 \][/tex]

  Now, find the two values of x:

[tex]\[ x_1 = \frac{-1.2 + 0.6928}{-0.012} = \frac{-0.5072}{-0.012} \approx 42.27 \] \[ x_2 = \frac{-1.2 - 0.6928}{-0.012} = \frac{-1.8928}{-0.012} \approx 157.73 \][/tex]

Therefore, the water arc reaches a height of 50 feet at approximately [tex]\( x = 42.27 \) feet and \( x = 157.73 \)[/tex] feet from the north shore.

I actually don't have enough information to complete this question but if you have a positive slope the line goes either up and right or down and left but when it is negative it goes down left or up right.
