Answer:

f'(2)=64

Step-by-step explanation:

After plugging in 2 for x our equation would look like

log(2^2+(3×2))×2^(3x2)

Now just follow PEMDAS, starting with the left.

1: 2^2=4, 3×2=6, 4+6= 10

2: 3×2=6, 2^6=64

3: log(10)=1

4: 1×64=64

5: f'(2)=64

The length of CE in the triangle is 20.

A triangle is a three-sided polygon that consists of three edges and three vertices.

From the given triangle ABC

BC=CD which are congruent sides

x-5=14

x=19

AB=DE

2x+3=6

2x=3

x=3/2

Now DE 2x+3=2(3/2)+3=6

The ratio of y to x gives the constant of proportionality, k = 5, therefore, they are proportional quantities.

If two variables of two quantities, x and y, are represented on a graph to show their relationship, they are proportional quantities if for every ratio of y to x, the value we get is the same, which means they have a constant of proportionality, k.

Using the points on the graph in the image attached below, the table can be completed as follows:

Part A:

Number of T-shirts (x): 1   2   3   4

Time in minutes (y):     5  10  15 20

Part B: Find the ratio of y to x for each of the points on the graph.

5/1 = 5

10/2 = 5

15/3 = 5

20/4 = 5

The table derived from the graph is:

Number of T-shirts (x): 1   2   3   4

Time in minutes (y):     5  10  15 20

B. The quantities are proportional.

The ratio of y to x gives the constant of proportionality, k = 5, therefore, they are proportional quantities.

AB vector is a vector whereas AB bar is a line segment.

What is a vector ?

The vectors are described as an object containing both significance and course. Vector describes the motion of an item from one point to any other. Vector math may be geometrically picturised via the directed line segment.

The duration of the phase of the directed line is known as the value of a vector and the angle at which the vector is inclined shows the path of the vector. The start line of a vector is referred to as “Tail” and the finishing factor (having an arrow) is referred to as “Head.”

The difference is in their names itself.

AB vector is a vector whereas AB bar is a line segment.

A vector has a direction and a magnitude while a line segment ( scalar ) has only magnitude.

Therefore, AB vector is a vector whereas AB bar is a line segment.

Sort the data: 41, 41, 43, 43, 45, 50, 52, 53, 54, 62, 63, 63, 67, 75, 97

Find the median (Q2): 53

Split the data set into two parts: Q1 (25th percentile) and Q3 (75th percentile)

Q1: 41, 41, 43, 43, 45, 50, 52, 53

Q3: 54, 62, 63, 63, 67, 75, 97

Find the median (Q1) of Q1 and the median (Q3) of Q3:

Q1 = 45

Q3 = 63

Finally, calculate the IQR by subtracting Q1 from Q3:

IQR = Q3 - Q1 = 63 - 45 = 18

So, the interquartile range of the given data set is 18. This means that 50% of the data falls within a range of 45 + 18 = 63 and 45 - 18 = 27.

The set of pairs for which x and y vary inversely is given as follows:

{(-1, -2/7), (4, 1/14), (6, 1/21)}.

(third set).

A direct proportional relationship is defined as follows:

y = kx.

In which k is the constant of proportionality.

For an inverse relation, the relation is modeled as follows:

y = k/x.

Meaning that when x increases, y decreases at a constant rate.

The constant is then obtained as follows:

k = yx.

Hence the third relation is then the relation for which x and y vary inversely, as:

k = -1 x -2/7 = 4 x 1/14 = 6 x 1/21.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Lydia has money in two savings accounts one rate is 8% and the other is 12%  and the total interest is $336. Let the amount invest in accounts be x and y respectively.
According to the question,
0.08x + 0.12y = 336 - - - - - -(1)

Again,
she has $350 more in 12% account
y = x + 350 - - - - - -(2)

Put y in equation 1,
0.08x + 0.12[x + 350] =336
0.08x + 0.12x + 42 = 336
0.20x = 336 - 42

Option D is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The exponential function is given as,

f(x) = m[tex]a^x[/tex]

Now,

From the table,

2 = m[tex]a^0[/tex]

m = 2

1 = m[tex]a^1[/tex]

m = 1/a ____(1)

0.5 = m[tex]a^2[/tex]
