The total surface area of this cuboid is 112^2
Find the value of x
length = 10cm
width = 2cm
Hight = x
The value of x is 3
How to solve for x?The given parameters are:
Length = 10cm
width = 2cm
Height = x
The surface area is calculated as;
Area = 2 *(lw + lh + wh)
So, we have:
2 * (10 * 2 + 2x + 10x) = 112
Evaluate the like terms and divide by 2
20 + 12x = 56
Subtract 20 from both sides
12x = 36
Divide by 12
x = 3
hence, the value of x is 3

Im taking precalc over edge 2022 right now. Cramming right before the deadline LOL. If i complete things after the deadline do they count for late credit?
Step-by-step explanation:
♦ Solution ♦ :-
Given Information :
The ratio of heights of the two girls = 5:7
Assumption
Consider their height be 5X cm and 7X cm
The height of the first girl = 5X cm
But According to the condition mentioned in given problem
The height of the first girl = 192 cm
=> 5X = 192
=> X = 192/5
=> X = 38.4
Therefore, X = 38.4 cm
Now the height of the second girl = 7X cm
=> 7 × 38.4 cm
=> 268.8 cm
♦ Alternative Method♦ :-
The ratio of the heights of the two girls = 5:7
The height of the first girl = 192 cm
Assume that the height of the second girl = X cm
Therefore, 5:7= 192:X
=> 5/7 = 192/X
=> 5X = 7×192
=> X = (7×192)/5
=> X = 7× 38.4
=> x = 268.8 cm
♦ Answer ♦ :-
The height of the second girl is 268.7 cm
use the distrubutive property to simply 2(-5-7j)
Answer:
2(-5 - 7j) = -10 - 14j
Step-by-step explanation:
Using the distributive property means that we have to multiply both -5 and -7j by 2:
2(-5 - 7j)
⇒ 2 × -5 + 2 × -7j
⇒ -10 - 14j

The domain and range is [-4, 4] and [0, 4]
What is Domain and range?The domain of a function is the set of values that we are allowed to plug into our function.
The range of a function is the set of values that the function assumes.
x² + y² = 16
y = √16 - x²
For domain under root should not be negative quantity,
16 - x²≥0
16≥x²
So, x≤4 or x≥4
Thus, the domain is [-4, 4]
Range:
y is maximum at x=0, y=4
y is minimum at x=4, y=0

calculate AC to 1 decimal place ?
Step-by-step explanation:
first we need to find the length of CD, so that we can use Pythagoras to find AC.
to get CD we use again Pythagoras. there is a smaller right-angled triangle on top of the BCD rectangle.
so, AD = 11 = 4 + 7
7 = the vertical leg of the upper right-angled triangle.
the horizontal leg is congruent to CD and is
sqrt(16² - 7²) = sqrt(256 - 49) = sqrt(207).
AC² = sqrt(207)² + 11² = 207 + 121 = 328
AC = sqrt(328) = 18.11077028... cm ≈ 18.1 cm

Write the equation in point-slope form of the line that passes
through the given point and has the given slope..
m= 5/3,(4, -2)
Answer:
y + 2 = 5/3(x - 4)
Step-by-step explanation:
Point-slope form of the equation of a line is a shortcut, fill-in-the-blank formula. You can write an equation just by filling in the slope and a point (hence the name, point-slope)
It looks like this:
y - Y = m(x - X)
The point given is (4,-2) fill in the -2 for the Y. Leave the first y just like it is, it stays a y. Fill in the 4 for X. Leave the first little x in the parenthesis alone Leave it an x.
y - -2 = m(x - 4)
Fill in the slope for the m.
y - -2 = 5/3(x - 4)
Simplify if possible.
y + 2 = 5/3 (x - 4)

The turning point of the parabola is (64, -43)
What is a turning point?Turning point is that point on a parabolic curve in which the gradient of the curve changes value.
It is also the point on the curve in which the curve starts rising or falling.
Analysis:

at turning point dy/dx = 0
dy/dx = 54x - 3456

54x = 3456
x = 3456/54 = 64
To find the value of y at x = 64

Function 1
graph of function f of x equals negative x squared plus 8 multiplied by x minus 15
Function 2
f(x) = −x2 + 2x − 3
Function 1 has the larger maximum at (1, 4).
Function 1 has the larger maximum at (4, 1).
Function 2 has the larger maximum at (1, −2).
Function 2 has the larger maximum at (−2, 1).
Answer:
Function 1 has the larger maximum at (4, 1)
Explanation:
After observation, graph of function 1 has vertex at Maximum (4, 1)
In order to find vertex of function 2, complete square the equation.
f(x) = -x² + 2x - 3
f(x) = -(x² - 2x) - 3
f(x) = -(x - 1)² - 3 + (-1)²
f(x) = -(x - 1)² - 2
Vertex form: y = a(x - h)² + k where (h, k) is the vertex
So, here for function 2 vertex: Maximum (1, -2)
Conclusion:Function 1 = Maximum (4, 1), Function 2 = Maximum (1, -2)
Function 1 has greater maximum value of (4, 1) as "1 is greater than -2"

Resolver y realizar la comprobacion del siguiente sistema de ecuacion aplicando el metodo grafico. [y=3-2x, y=8-7x
The solution for the system of equations: y = 3 - 2x and y = 8 - 7x, is x = 1, y = 1.
In the question, we are given a system of equations,
y = 3 -2x ... (i), and
y = 8 - 7x ... (ii).
We have been asked to solve the given system of equations.
To solve the system of equations, we do as follows:
Substitute the value of y = 3 - 2x, from (i) in (ii), to get:
y = 8 - 7x,
or, 3 - 2x = 8 - 7x, which is a linear equation in one variable.
To solve this, we follow these steps:
3 - 2x = 8 - 7x,
or, 3 - 2x + 7x = 8 - 7x + 7x {Adding 7x to both side of the equation},
or, 3 + 5x = 8 {Simplifying},
or, 3 + 5x - 3 = 8 - 3 {Subtracting 3 from both sides of the equation},
or, 5x = 5 {Simplifying},
or, 5x/5 = 5/5 {Dividing both sides of the equation by 5},
or, x = 1.
Substituting x = 1, in (i), we get:
y = 3 - 2x,
or, y = 3 - 2(1),
or, y = 3 - 2 = 1.
Thus, the solution for the system of equations: y = 3 - 2x and y = 8 - 7x, is x = 1, y = 1.
