what is the surface area of a box if it’s volume is 2244 inches cubed?
I wasn’t given any measurements, just the volume.
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:

Find the missing lengths of the sides
ANSWER
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:
NUMBER3
Step-by-step explanation:
Table no 3 is representing here a non-linear function.
Why table 3 is 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.

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°

When the length of a rectangle with a width of 1/6 foot was increased by 2/3 foot, the area of the rectangle became 11/72 square feet. Find the original length of the rectangle. Explain your reasoning.
Answer:
1/4 is the original length
Step-by-step explanation:
The original length of the rectangle is 11/72 square feet. To get the area of a rectangle, you multiply the length x width.
You already know the width in this problem. The width is 1/6 feet. So, divide the area (11/72 feet) by the width (1/6 feet) to get the length, 11/12 feet.
However, the original length was increased by 2/3 feet. So, take our new length (11/12 feet) and subtract the increased length (2/3 feet) from it. When you do that, you get 1/4 feet.
Therefore, the answer is 1/4 feet. Hope this helps! :)

Which of the following linear equations in standard form contains points (-2,4) and (3,9)?
Answer:
y=x+6
Step-by-step explanation:
If you need to find a standard linear equation from two points, you have to first find the slope, then find the y intercept.
To find the slope, you should do the change in y over the change in x.
that would be:
(4-9)/(-2-3)
(-5)/(-5)
the slope is 1
plug that in along with values of x and y taken from known point (3,9) to the standard equation of a linear relationship:
y=mx+b
m=1
y=9
x=3
b=?
9=(1)(3)+b
9=3+b
b=6
The equation of the line would be y=x+6
Answer:
x - y = - 6
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (3, 9)
m = [tex]\frac{9-4}{3+2}[/tex] = [tex]\frac{5}{5}[/tex] = 1, hence
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 9), then
9 = 3 + c ⇒ c = 9 - 3 = 6
y = x + 6 ← equation in slope- intercept form
Subtract y from both sides
0 = x - y + 6 ( subtract 6 from both sides )
- 6 = x - y, thus
x - y = - 6 ← in standard form

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

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.

A fountain shoots a water arc that can be modeled by the graph of the equation y=-0.006x^2+1.2x+10, where x is the horizontal distance (in feet) from the river's north shore and y is the height (in feet) above the river. Does the water arc reach a height of 50 feet? If so, about how far from the north shore is the water arc 50 feet above the water?
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.
