If a rectangular prism has dimensions of 2cm by 2 cm by 5 cm, then the surface area of the rectangular prism is 48 centimeter square
The length of the rectangular prism = 2 cm
The width of the rectangular prism = 2 cm
The height of the rectangular prism = 5 cm
The surface area of the rectangular prism = 2(lw+lh+hw)
Where l is the length
w is the width
h is the height
Substitute the values in the equation
The surface area of the rectangular prism = 2(2×2+2×5+2×5)
= 2(4+10+10)
= 2×24
= 48 centimeter square
Hence, if a rectangular prism has dimensions of 2cm by 2 cm by 5 cm, then the surface area of the rectangular prism is 48 centimeter square

Jerome is constructing a table of values that satisfies the definition of a function.
It is important to know that a function associates to every elemento of x a unique element of y. In other words, x-values should no repeat. Having said that, we can't fill the blank with -1, 0, 11, or 17.
Hence, the answers are -5 and 2. Find the value of p if the sum of negative 4
and the quantity p divided 5 is sixteen.

What is a linear equation example?
Ax+By=C is the usual form for two-variable linear equations.As an illustration, the conventional form of the linear equation 2x+3y=5 When an equation is given in this format, finding both intercepts is rather simple (x and y).A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.6x +4(x - 10) = 140.
6X + 4X - 40 = 140

The equation of the parabola is x² = 60y after applying the concept of the parabola.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
(x - h)² = 4a(y - k)
(h, k) is the vertex of the parabola:
a = √[(c-h)² + (d-k²]
(c, d) is the focus of the parabola:
It is given that:
Focus of (0, 15) and directrix y = –15.
Let (x, y) be on the parabola:
The distance between focus and (x, y):
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\rm d=\sqrt{(x-0)^2+(y-15)^2}[/tex]
[tex]\rm d=\sqrt{x^2+(y-15)^2}[/tex]
Directrix y = -15
y + 15 = 0
[tex]\rm \sqrt{x^2+(y-15)^2} = |y + 5|[/tex]
Squaring both sides:
x² + (y - 15)² = (y + 15)²
x² + y² -30y + 225 = y² + 30y + 225
x² -30y = 30y
x² = 30y + 30y
x² = 60y
Thus, the equation of the parabola is x² = 60y after applying the concept of the parabola.

I need it in slope intercept form and it has to be PERPENDICULAR to the equation it gives.
The equation of the line in slope intercept form perpendicular to 6x - 2y = 12 and has the same y-intercept is y = - 1 / 3 x - 6
How to find equation in slope intercept form?The equation in slope intercept form can be represented as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the equation of the line is perpendicular to 6x - 2y = 12 and have the same y-intercept.
Hence, perpendicular lines follows the rule below:
m₁m₂ = -1
6x - 2y = 12
6x - 12 = 2y
y = 3x - 6
Hence,
3m₂ = -1
m₂ = - 1 / 3
Therefore, the slope of the line is - 1 / 3.
The y-intercept is -6

The equation of the line will be y = 2x + 1.
What do we mean by the equation of the line?The set of points that make up a line in a coordinate system is represented algebraically by a line's equation. An equation of a line is an algebraic expression that represents the many points that together make up a line in the coordinate axis as a set of variables, x, and y.So, the equation of the line:
The equation is parallel to y = 2x -2 and the slopes equation is y = mx + b where m is the slope.So, the slope is 2.Then, y = 2x + b
Now, substitute x = 1 and y = 3 in the above equation to find b:
y = 2x + b3 = 2(1) + bb = 3 - 2b = 1So, the equation of the line will be: y = 2x + 1

A person 1.85 m tall walks towards a lamppost on level ground at a rate of 0.5 m/sec. The lamp on the post is 5 m high. At which rate is the tip of the person's shadow moving toward the lamppost when the person is 4 I from the post? Please enter your answer in decimal format with three decimal places.
Using the Pythagorean Theorem and implicit differentiation, it is found that the tip of the person's shadow is moving toward the post at a rate of 0.393 m/sec when the person is 4 m from the post.
What is the Pythagorean Theorem?The Pythagorean Theorem is a geometry axiom that relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, stating that the hypotenuse squared is the sum of the legs squared, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In the context of this problem, we have that:
The distance d between the person's shadow and the lamp is the hypotenuse of a right triangle.The legs are the person shadow and the lamp.Hence the following relation between these variables is established:
d² = x² + y².
Applying implicit differentiation, the rate of change of the distance is given as follows:
[tex]d\frac{dd}{dt} = x\frac{dx}{dt} + y\frac{dy}{dt}[/tex]
The height remains constant, hence:
[tex]\frac{dy}{dt} = 0[/tex]
The other parameters are given as follows:
y = 5 - 1.85 = 3.15 m (vertical distance).x = 4 m (distance of the person from the post).dx/dt = 0.5 m/s (velocity of the person).Hence the distance at the desired instant is:
d² = 4² + 3.15²
d = sqrt(4² + 3.15²)
d = 5.091 m
The rate of change of the distance is found as follows:
5.091dd/dt = 4 x 0.5
dd/dt = 2/5.091
dd/dt = 0.393 m/sec.

The correct range of definition is;
[tex]C;\text{ -5}\leq x<1[/tex]Here, we want to get the range of values of x for which the given expression is defined
The key here is that any value of x that will make us have a negative value inside the root will make the expression undefined as that would give us a non-real root
Now, let us take a look at the options;
a) if x is greater than 1, we will have a negative root on the right, making the expression undefined. This option is wrong
b) This is also wrong; if 5 is less than x, then x might be 6 , which would give a negative root value
c) If -5 is less than x, x could take values of -4, -3, -2 and the root on the right will never be negative. But in cases like this, we have the spectrum upto positive values of x such as 5 which would make the root on the right negative and undefined. This range here is the correct answer
d) Here, 5 is greater than x, so the root on the left can never be negative. For values less than -1, like -6, what we have on the left will be undefined
