Estimate L4 and R4 over [0,7] for the function f(x) = 6x^2
The value of L4 and R4 over [0,7] for the function f(x) = 6x² will be 2[2√0 + 2√2 + 2√4 + 2√6] and 2[2√2 + 2√4 + 2√6 + 2√8] respectively.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that the function is,
I'm assuming that you mean the left and right Riemann sums with four equal subintervals when you refer to L4 and R4.
If so, then Δx = (8-0)/4 = 2, and f(x) = 2√x.
L4 = f(0)Δx + f(2)Δx + f(4)Δx + f(6)Δx
L4 =2[2√0 + 2√2 + 2√4 + 2√6]
R4 = 2[2√2 + 2√4 + 2√6 + 2√8]
Thus, the value of L4 and R4 over [0,7] for the function f(x) = 6x² will be 2[2√0 + 2√2 + 2√4 + 2√6] and 2[2√2 + 2√4 + 2√6 + 2√8] respectively.

reduce the following ratio to their lowest terms 1km to 250m
The ratio in their lowest terms is 4:1
What is a ratio?
A ratio displays the multiplicity of two numbers. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The proportion of lemons to oranges is also 6:8.
We are given two values 1km and 250m
We known that 1km = 1000m
Hence we have to find the ratio of the value 1000m to 250m
To find the ratio just Divide the two numbers we get
1000/250
=4/1
=4:1
Hence the smallest ratio for the term is 4:1

If g(x) is the image of y=−2x^2−20x+2 after a translation right 4 units and up 2 units, write the equation of g(x) in the standard form of a quadratic function and describe its graph.
Enter the quadratic expression in standard form, a(x−h)2+k .
The standard form equation is g(x)=
The image of y = −2x^2 − 20x + 2 after a translation right 4 units and up 2 units is written in:
the form a(x−h)^2 + k is -2(x + 1)^2 - 107standard form of the equation is g(x) = -2x^2 - 4x - 108The graph will be a vertical parabola opening downwards
How to get the transformation imagewhen the function y = −2x^2 − 20x + 2 translates right 4 units it gives
y = -2(x - 4)^2 − 20(x - 4) + 2
going up two units
y = -2(x - 4)^2 − 20(x - 4) + 2 + 2
simplifying the equation further gives
y = -2(x - 4)(x - 4) − 20(x - 4) + 4
y = -2(x^2 - 8x + 16) - 20x - 80 + 4
y = -2x^2 + 16x - 20x - 32 - 80 + 4
y = -2x^2 - 4x - 108
completing the square

32°
44°
88°
136°
The measure of angle H is 44°. in the parallelogram.
What is parallelogram?
A unique variety of quadrilateral made up of parallel lines is known as a parallelogram. A parallelogram can have any angle between its adjacent sides as long as its opposite sides are parallel. If two opposite sides of a quadrilateral are parallel and congruent, it will be a parallelogram. Consequently, a quadrilateral in which both pairs of opposite sides are parallel and equal is known as a parallelogram.
We can solve this easily using alternative interior angles. A parallelogram's interior is always 360 degrees, right?
(4x + 16)° + (2x - 16)° = 180
6x = 180
x = 180/6 = 30
So the angle H = 2*30 - 16 = 44°
To visualize the parallelogram, drawing it out is always helpful. Greg S., a widely renowned mathematician who specializes in geometry, says the answer is 44 degrees.
Hence The measure of angle H is 44°.

If tan x° = e divided by 8 and sin x° = e divided by f, what is the value of cos x°?
cos x° = 8 divided by f
cos x° = f divided by 8
cos x° = 8f
cos x° = 8e
The value of cos x° is 8 divided by f
How to find the value of cos x°?
We will use trigonometrical ratios to solve this problem. Below are the definitions of the trigonometrical ratios:
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent or tan = sin/cos
The opposite is the side the angle of consideration is facing
The hypotenuse is the side the right angle is facing
The adjacent is the side left after determining the opposite and hypotenuse
Given: tan x° = e/8 and sin x° = e/f
Since tan = opposite/adjacent, that means in tan x° = e/8, opposite = e and adjacent = 8. Also, sin = opposite/hypotenuse, so in sin x°= e/f, hypotenuse = f
And cos = adjacent/hypotenuse. Thus, cos x° = 8/f.
Therefore, the value is cos x° = 8 divided by f is the answer. Pick the first option
