Answer:
6xsinx + 3x²cosx
Step-by-step explanation:
Differentiate using the product rule
Given y = f(x)(g(x) , then
[tex]\frac{dy}{dx}[/tex] = f(x)g'(x) + g(x)f'(x)
Here f(x) = sinx ⇒ f'(x) = cosx
g(x) = 3x² ⇒ g'(x) = 6x
Thus
[tex]\frac{dy}{dx}[/tex] = 6xsinx + 3x²cosx

Answer:
6x= 42
x= 7
Step-by-step explanation:
a) Area= length ×width
2100= 50 ×width
width= 2100 ÷50
width= 42 ft
Thus, the field is 42ft wide.
b) width of field
= x +3x +2x
= 6x
Since we know that the field is 42ft wide from (a),
Equation: 6x= 42
x= 42 ÷6
x= 7

True or False? (-x)^6 = -x^5 Explain your
answer (use either words or an example).
Answer:
False
Step-by-step explanation:

- [tex]x^{5}[/tex] = - [tex]x^{5}[/tex]
Thus
[tex](-x)^{6}[/tex] ≠ - [tex]x^{5}[/tex]
True or False, the chance of flipping heads on a coin 3 times in a row is 1/2
true flip a coin it's fifty fifty
Answer:
False
Step-by-step explanation:
Each toss is an independent event, so the probability of three tosses of heads in a row is the product of the three probabilities..
Each probability of heads is
p(heads) = 1/2
p(heads, heads, heads) = p(heads) * p(heads) * p(heads) = 1/2 * 1/2 * 1/2 = 1/8

work it out "the equation 1.5r + 15=2.25r represents the number r of movies u must rent to spend the same amount at each movie store. how many movies must u rent to spend the same amount at each movie store" then there's 2 pics one says "all rentals $1.50, membership fee $15" other says "membership free, all rentals $2.25"
Answer:
20
Step-by-step explanation:
Your equation is correct. To solve it subtract 1.5r from both sides and divide by the resulting coefficient of r.
15 = 0.75r
15/0.75 = r = 20
You must rent 20 movies for the costs to be the same.

Step-by-step explanation:
Jackson was selling cups of lemonade. On Saturday, he sold a total of 14 cups. On Sunday he sold cups at a steady rate of 3 cups per hour. Set up and solve an equation to find how many hours, h, it took Jackson to sell 47 cups (including those from Saturday).
Answer:
(47-14) h ÷ 3 =11
Step-by-step explanation:
47-14=33
33 divided by 3 is 11
Jackson takes 11 hours to sell 47 cups.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of hours that Jackson sold his cups on Sunday.
Now,
Saturday cups + Sunday cups = Total cups.
14 + 3x = 47
3x = 33
x = 11
Hence "Jackson takes 11 hours to sell 47 cups".

Which of the quadratic functions listed is written in standard form?
O A. Y= 2x² + 3x - 5
O B. Y-4 = - 3(x - 5)
OC. Y - 7 = -2(x + 3)?
O D. Y= (x+1)(x – 5)
Answer: A
Step-by-step explanation:
f(x)=ax²+bx+c is the standard form for quadratic functions. Looking at the answer choices, we can eliminate B, C, D. They are not the same as the given standard form. B and C are point-slope formulas, which are not standard form. D is in intercept form, therefore it is not standard form. This leaves us with A as the correct answer.

Marcus and Emma went to the store together. Marcus had $2.00 and Emma had $4.50. Together they spent $6.00. What expression could be used to find the combined amount Marcus and Emma have left?
Answer:
$6.00-($2.00+$4.50)
in other terms, 6 - (2 + 4.5)
Step-by-step explanation:
So first, we know that they spent 6 in total. To figure out how much they spent, we need to figure out how much they had all together.
To get how much all together, we have to add. 2 + 4.5
Now that we now how to get the total amount, out them in parentheses and add the 6 infront.
Since we need to find the remaining amount, were subtracting 6 from the total, hence the parentheses.
All this leads to the expression: 6 - (2 + 4.5)

A field in the shape of a square has an area of 8,100 square feet. How can you determine the length of one side of the field?
To determine the length of one side use the formula for the area of square. As a square is equal on all four sides, finding one length results in any of the four. Solve using the formula and you receive your answer of 90.
A = s²
8100 ft² = s² (set up formula)
√8100 ft² = s² ( get s alone by squaring both sides)
90 ft = s (answer)
We can conclude that the side of the given square with an area of 8100ft² is 90ft.
What is a square?A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles. It can alternatively be explained as a rectangle with two neighboring sides that are of equal length. A square is a two-dimensional plane object in geometry that has four equal sides and four equal but 90-degree angles.So, the area of the square is 8100ft².
Formula: s²So, we know that: 8100 = s²Now, calculate for s as follows:
s² = 8100s = √8100s = 90ftTherefore, we can conclude that the side of the given square with an area of 8100ft² is 90ft.
