differentiate t²sin(2t)
Answer:
[tex]\displaystyle \large{y\prime = 2t \sin (2t) + 2t^2 \cos (2t)}[/tex]
Step-by-step explanation:
We are given a function:
[tex]\displaystyle \large{y = t^2 \sin (2t)}[/tex]
To differentiate a function, we are going to use the product rules since there are two functions which are t^2 and sin(2t) multiplying together.
From the product rules, [tex]\displaystyle \large{y = f(x)g(x) \to y\prime = f\prime (x) g(x)+f(x) g\prime (x)}[/tex]
Therefore, [tex]\displaystyle \large{y = t^2 \sin (2t) \to y\prime = (t^2)\prime \sin (2t) + t^2 (\sin (2t))\prime}[/tex]
Before we start differentiating, I’d like you to look at [sin(2t)]’. A function like this, you cannot just directly derive and answer. You need to use chain rules.
We know that, [tex]\displaystyle \large{y = \sin (x) \to y\prime = \cos (x)}[/tex] but what if the “x” is another function? Like sin(3x), sin(x^2) as examples. The insides are another function, can be expressed as fog(x) or gof(x) is composite function.
Basically, chain rule is a rule or formula for composite function and it’s the most common and useful as well as being always used in differentiation.
Chain Rules
[tex]\displaystyle \large{\frac{dy}{dx} = \frac{dy}{du} \frac{du}{dx}}[/tex]
where u is another function in a bracket. From the formula above, it can be also written as:
[tex]\displaystyle \large{[f(g(x))]\prime = f(g(x))\prime \cdot g(x)\prime[/tex]
To simply say, you differentiate the whole function first then multiply with the chain or inner derived function.
So from the function, we obtain:
[tex]\displaystyle \large{y\prime = 2t \sin (2t) + t^2 \cos (2t) \cdot (2t)\prime}\\ \displaystyle \large{y\prime = 2t \sin (2t) + t^2 \cos (2t) \cdot 2}\\ \displaystyle \large{y\prime = 2t \sin (2t) + 2t^2 \cos (2t)}[/tex]
The factored form would be:
[tex]\displaystyle \large{y\prime = 2t ( \sin (2t) + t \cos (2t))}[/tex]
From above, for polynomial function, to differentiate, you can do by using the power rules.
Power Rules
[tex]\displaystyle \large{y = ax^n \to y\prime = nax^{n-1}}[/tex]

Step-by-step explanation:
Which graph represents this system? 2x-5v=-5 y=-3x+1
Answer:
Please check the attached graph.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the system of equations
2x - 5y = -5 --- [Equation 1]
y = -3x + 1 --- [Equation 2]
converting the equation 1 in the slope-intercept form
2x - 5y = -5
5y = 2x+5
divide both sides by 5
y = 2/5x + 1
Thus, the y-intercept = 1
Now, please check the attached graph below.
The red line represents the equation 2x - 5y = -5
From the graph, it is clear that the red line has the y-intercept y = 1.
Now, considerng the equation 2
y = -3x + 1
comparing with the slope-intercept form of line equation
The y-intercept b = 1
Hence, the y-intercept of the line y = -3x + 1 is y = 1
The green line represents the equation y = -3x + 1
From the graph, it is clear that the green line has the y-intercept y = 1.
Point of Intersection:
It is clear from the graph:
The red line represents the equation 2x - 5y = -5.The green line represents the equation y = -3x + 1.As both lines meet or intersect at the point (0, 1).
Therefore, the point of intersection of both the lines is:
(x, y) = (0, 1)
As we know that the point of intersection of both the lines represents the solution to the system of equations.
Therefore, (0, 1) on the graph represents the solution to the system of equations.
The graph is attached below.

question 3, thanks for the help :)
Answer:
The slope of the line passing through (1, 2) and (3, 8) is:
Slope = 3
Step-by-step explanation:
Given the points
(1, 2)(3, 8)Here:
(x₁, y₁) = (1, 2)
(x₂, y₂) = (3, 8)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [8 - 2] / [3 - 1]
= 6 / 2
= 3
Thus, the slope of the line passing through (1, 2) and (3, 8) is:
Slope = 3

Find the length of BC, in simplest radical form.
9514 1404 393
Answer:
BC = 16 +12√3
Step-by-step explanation:
In the attached, we see that ∆ABE is a 30°-60°-90° triangle with AB the short side and BE the hypotenuse. Then BE = 2·AB = 12√3.
EC is the side opposite AD in parallelogram ADCE, so is the same length, 16.
The length BC is ...
BC = EC +BE
BC = 16 +12√3

Step-by-step explanation:
Donna deposits $275 into her savings account. She leaves the money in her account,
untouched, for 6 years. If the account earns 4.5% simple interest each year, how much simple
interest will she have earned by the end of the sixth year?
$7,425.00
$74.24
$206.25
$12.38
The simple interest earned by Donna by the end of the sixth year is $74.24
What is simple interest?Simple interest is the interest charge on borrowing that's calculated using an original principal amount only and an interest rate that never changes.
Given that, Donna deposits $275 into her savings account for 6 years, the account earns 4.5% simple interest each year,
We need to find the interest earned by the end of the sixth year
Simple Interest = PRT / 100
Where,
P = Principal ($275)
R = rate (4.5%)
T = time (6 years)
SI = 275 × 6 × 4.5 / 100
= 7425 / 100
= 74.25
Hence, the simple interest earned by Donna by the end of the sixth year is $74.24
