f(x)= 3x; translation up 5 units
After applying the given translation we get the function as 3x + 5
Graph translation is the process of converting an equation or existing graph into a new graph.
One common type of algebraic issue is changing algebraic equations.
A parent function's graph is altered by a translation. The three different types of translation are dilations, reflections, and translations.
A function can have its y-values modified vertically or its x-values changed horizontally (affects the x-values).
We are aware that the x- and y-coordinates must be modified to reflect the translation by the specified amount.
f( x ) = 3x is translated 5 units upwards.
Therefore the required graph is f ( x ) = 3x + 5 .

The amounts of e-waste generated in a region during two years were 14,200,000 tons and 10,700,000 tons. What was the total e-waste generated over these two years in the region, expressed in scientific notation? (5 points)
Group of answer choices
2.49 ⋅ 1014 tons
2.49 ⋅ 107 tons
24.9 ⋅ 1014 tons
24.9 ⋅ 107 tons
The total e-waste generated over these two years in the region, expressed in scientific notation, is B. 2.49 x 10^7 tons.
What is a scientific notation?Scientific notation is a standard form of expressing a short or large number in a decimal form.
Scientific notation involves writing a number that is greater than 1 but less than 10 with the power of 10.
Correct scientific notations express numbers as products of a number between 1 and 10 multiplied by an appropriate power of 10 based on its place value in the given decimal.
Thus, the total e-waste generated cannot be expressed in scientific notation as Options A, C, or D because these do not comply with the rules of scientific notations, unlike Option B.

2. Expand each of the following functions in ascending powers of x up to the term in
x³. In each case state the values of x for which the expansion is valid.
Values of x in ascending orders is shown below.
What are exponents?The number of times a number has been multiplied by itself is referred to as an exponent. For instance, the expression 2 to the third (written as 2³) signifies 2 x 2 x 2 = 8. 2³ and 2 x 3 = 6 are not equivalent. Keep in mind that any number is itself when raised to the power of 1. Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward fashion. To illustrate 3 x 3 x 3 x 3 in a straightforward manner, for instance, we could write it as 34, where 4 is the exponent and 3 is the base. It is claimed that the entire statement 34 has power.

The equation for lines can be written as y=–10x+5/4. Parallel to line's is line t, which passes through the point (1,3). What is the equation of line t?
Step-by-step explanation:
what I understood :
line s : y = -10x + 5/4
the slope is always the factor of x (here : -10).
a parallel lines must have the same slope.
line t : y = -10x + b
to get b we use the coordinates of the given point :
3 = -10×1 + b = -10 + b
13 = b
line t : y = -10x + 13

what is the probability that maximum speed differs from the mean value by at most 2.5 standard deviations? (round your answer to four decimal places.)
The probability that maximum speed differs from the mean value by at most 2.5 standard deviations is 0.8473
Let the required probability that the maximum speed of mopeds differs from the mean speed by 2.5 standard deviations be given by P(U±2.5).
Mean speed U =46.7km/hr
P(46.7±2.5) = (44.2<= X <=49.2)
= P( 44.2<= Z <= 49.2)
= P(44.2 - 46.7/1.75 <= Z <= 49.2- 46.7/1.75)
= P( - 1.4286 <= Z <= 1.4285)
= P(1.4285) - P(-1.4285)
= P(1.43 ) - P(-1.43)
= 0.92364 - 0.07636
= 0.8473
Thus the probability that maximum speed differs from mean value by at most 2.5 standard deviations is 0.8473
the question is incomplete and the full question is "Mopeds (small motorcycles with an engine capacity below 50 cm3) are very popular in Europe because of their mobility, ease of operation, and low cost.

Darlene has 6 3/4 gallons of gasoline. Every time she mows her lawn, she uses 3/8 gallon. How many times can she mow her lawn before she needs more gas?w
The number of times Darlene mow her lawn before she needs more gasoline is equal to 18times.
As given in the question,
Total gasoline with Darlene is equal to 6 3/4 gallons
Convert mixed fraction into proper fraction:
6 3/4 = 27/4 gallons
Every time amount of gasoline used to mow her lawn = 3/ 8gallon
Number of times Darlene mow her lawn before she needs more gasoline
= (27 / 4) ÷ (3 /8)
= (27 /4) × (8/3)
= 18 times
Therefore, the number of times Darlene mow her lawn before she needs more gasoline is equal to 18times.

A study on students drinking habits wants to determine the true average number of alcoholic drinks all uf greek students have in a one week period. We know from preliminary studies that the standard deviation is around 6. 3. How many students should be sampled to be within 0. 5 drink of population mean with 95% probability?.
Number of students need to be sampled = 610
A study to determine the true average number of alcoholic drinks consumed by Greek students is conducted.
Standard Deviation, σ = 6.3
Margin Error of population mean, E = 0.5
Probability = 95% = 0.95
The p-value corresponding to 0.95 probability = (1+0.95)/2 = 0.975
The z-score corresponding to this p-value = 1.96 [from the z-tables]
Now, The margin error, E = zσ/√n, where n is the sample size
⇒ n = (zσ/E)²
⇒ n = (1.96 x 6.3/0.5)²
⇒ n ≈ 610
Hence 610 students need to be sampled.

Graph the image of the figure using the transformation given.
A graph of the image of figure Q'R'S'T' after a dilation of 2 units about the origin is: graph C.
What is dilation?Dilation simply refers to a type of transformation which changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.
What is scale factor?A scale factor can be defined as the ratio of two (2) corresponding length of sides or diameter in two similar geometric figures such as triangles.
Note: Each interval on this graph represents 1 unit.
For the given coordinates, the dilation with a scale factor of 2 about the origin or a center of dilation (0, 0) should be calculated as follows:
Point Q (-2, -1) → Point Q' (-2 × 2, -1 × 2) = Point Q' (-4, -2).
Point R (-1, 2) → Point R' (-1 × 2, 2 × 2) = Point R' (-2, 4).
Point S (1, 0) → Point S' (1 × 2, 0 × 2) = Point S' (2, 0).
Point T (2, -2) → Point T' (2 × 2, -2 × 2) = Point T' (4, -4).

6 = hj + k ( subtract k from both sides )
6 - k = hj ( isolate j by dividing both sides by h )
[tex]\frac{6-k}{h}[/tex] = j
(5)
[tex]\frac{v}{w}[/tex] = 9 ( multiply both sides by w to clear the fraction )
9w = v ( divide both sides by 9 )
w = [tex]\frac{v}{9}[/tex]
(8)
A = [tex]\frac{1}{2}[/tex] bh ( multiply both sides by 2 to clear the fraction )
2A = bh ( divide both sides by h )
[tex]\frac{2A}{h}[/tex] = b
(10)
V = [tex]\frac{1}{3}[/tex] πr²h ( multiply both sides by 3 to clear the fraction )
3V = πr²h ( isolate h by dividing both sides by πr² )
[tex]\frac{3V}{\pi r^2}[/tex] = h
(12)
V = πr²h ( isolate r² by dividing both sides by πh )
[tex]\frac{V}{\pi h}[/tex] = r² ( take square root of both sides )
[tex]\sqrt{\frac{V}{\pi h} }[/tex] = r
