The derivative is f'(x) = 5.
The limit definition of the derivative tells us that the derivative of a function is f is
f' (x) = [tex]\lim_{h \to \0} 0[/tex] [tex]\frac{f(x+h)-f(x)}{h}[/tex]
For this, f(x) = 5x and f(x + h) = 5(x + h)
So:
f'(x) = [tex]\lim_{h \to \}0[/tex] [tex]\frac{5(x+h)-5x}{h}[/tex]
= [tex]\lim_{h \to \}0[/tex] [tex]\frac{5x+5h-5x}{h}[/tex]
= [tex]\lim_{h \to \}0[/tex] [tex]\frac{5h}{h}[/tex]
= [tex]\lim_{h \to \}0[/tex] 5
= 5
So, when f(x) = 5x , we see that its derivative is f'(x) = 5.

Given: triangle ABC,
Angle B=120°,
AB= 6, BC = 10
Find: The area of triangle ABC
The area of triangle ABC when Angle B=120°, AB= 6, BC = 10 is 25.980 square unit.
As per the question statement, we are supposed to find out the area of triangle ABC in which angle B=120°, AB= 6, BC = 10.
Lets find out AC for which we should know about Cosine formula
i.e., [tex]AC^{2} =AB^{2} +BC^{2} -2(AB)(BC)cos(B)\\AC^{2} =6^{2} +10^{2} -2*6*10cos120\\AC^{2}= 36+100-120*(-0.5)\\AC^{2}=196\\AC=\sqrt{196} =14[/tex]
Hence We have measures of all three sides of the triangle ABC.
Now we use the Heron's formula for calculating the area of triangle ABC.
We need semi perimeter i.e., [tex]s=\frac{AB+BC+AC}{2}[/tex]
[tex]s=\frac{30}{2} =15[/tex]
Now Area is given by,
[tex]area=\sqrt{s(s-AB)(s-BC)(s-AC)} \\area=\sqrt{15(15-6)(15-10)(15-14)} \\area=\sqrt{15*9*5*1} \\area=\sqrt{675} \\area = 25.980 unit^{2}[/tex]
Area: The space occupied by an object or a shape in square units.Cosine Formula: Uses the cosine of an angle to determine the remaining sides of the triangle.Heron's Formula: Uses the measure of the all sides of triangle to calculate the area of the triangle.To learn more about Heron's questions, click on the link given below:

Step-by-step explanation:
(4h⁴)⁴ / (4h^-8)
remember, multiplying exponents means adding them. exponents of exponents means multiplying them.
and dividing exponents means subtracting them.
also, n^-a = 1/(n^a).
let's look at the numerator (top part) first :
(4h⁴)⁴ = 4^1×4 × h^4×4 = 4⁴×h¹⁶
now, for the denominator, the exponent -8 applies only to h. not to 4.
so,
1/(4h^-8) = h⁸/4
and so, the whole expression is then simplified
4⁴×h¹⁶ × h⁸/4 = 4³ × h²⁴

Write a difference quotient that best approximates the instantaneous rate of change of g at x=2.5.
A difference quotient that best approximates the instantaneous rate of change of g at x=2.5 is; -3
What is the Difference Quotient?We can define the average rate of change of a function g(x) in an interval [a, b] as:
r = [g(b) - g(a)]/(b - a)
Particularly, if we want to find an approximation of the rate of change for a particular value x', we can choose:
a < x' < b
Such that a and b are really close to x'.
Then if we want to find the instantaneous rate of change of g at x = 2.5, we need to find values of a and b really close to 2.5.
Looking at the graph, we can choose:
a = 2
b = 3
(are the two closer ones to 2.5)
Then the rate of change can be written as:
f'(x) = g(3) - g(2)]/(3 - 2)
f'(x) = (1 - 4)/1
f'(x) = -3
Thus, we can conclude that a good approximation of the instantaneous rate of change is -3.

A bag contains 3 red marbles, 5 blue marbles and 4 green marbles. If
two marbles are drawn out of the bag, what is the exact probability
that both marbles drawn will be red?
+-
Answer:
Submit Answer
the probability of drawing 2 red marbles from the bag will be 0.0455.
Number of Red marbles = 3
Number of blue marbles = 5
Number of green marbles = 4
Total marbles = 3 + 5 + 4 = 12
Probability of drawing 2 red marbles from the bag will be:
P = 3 / 12 × 2 / 11
P = 6 / 132
P = 3 / 66
P = 1 / 22
P = 0.0455
Therefore, the probability of drawing 2 red marbles from the bag will be 0.0455.

There is no relationship between the number of movies and the number of sleep hours.
What is a relationship?It is always a thing of importance to show data by the use of a scatter plot. The scatter plot must always have two axes. The vertical (y axis ) and the horizontal (x axis). It is always common to plot the independent variable on the x axis and the dependent variable on the y axis.
The scatter plot thus represented shows how one variable is related to another. In this case, we are trying to obtain how the number of sleep hours tend to be related with the number of movies and this has been shown on the scatter plot that is shown in the question above.
It is clear from the statements in the question that the line of best fit would show that as the number of movies remained constant, the number of sleep hours decreased. This now implies that there is no relationship between the number of movies and the number of sleep hours.

The simplified form of the algebraic expression is [tex]\frac{23}{10} p+\frac{6}{5} r[/tex] .
An expression constructed using integer constants, variables, and algebraic operations is known as an algebraic expression in mathematics (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number).
A good example of an algebraic expression is 3x² + 2xy + c.Any expression that can be converted into a rational fraction using the properties of the arithmetic operations is said to be rational (commutative properties and associative properties of addition and multiplication, distributive property and rules for the operations on the fractions). In other terms, a rational expression is one that can be created using only the four arithmetic operations and the variables and constants.Given expression is of the form:
[tex]\frac{3}{5} (\frac{1}{2}p+2r )+2p[/tex]
Now we will use the distributive property to expand the algebraic expression:

If angle 5 is 120 degrees, find the value of <8
Answer:Answer:
The measurement of the angle is 60
Step-by-step explanation:
The two blue lines are straight and parallel lines. The sum of the angles on a straight line is 180 degrees. Angle 5 and angle 6 are on a straight line. Therefore
Angle 5 + angle 6 = 180
If angle 5 is 120 degrees, then
Angle 6 = 180 - 120 = 60 degrees.
for a randomly selected worker, what is the approximate probability the bolt will be inserted in 19 minutes or less? round to the nearest whole percent.
The probability that the bolt will be inserted in 19 minutes or less is 0.8413.
How to calculate the probability?It should be noted that the probability will be illustrated as:
P(X < x) = P[z < (x - u/sd)]
where
x = number
u = mean
SD = standard deviation
Therefore given the numbers, this will be:
P(x < 19) = P(z < (19 - 15)/4)
= P(z < 4/4) = P(z < 1)
= 0.8413
