Differentiate from first principle
1. y= x^2 + 3x
2. y= x^2 + 3x + 8
Answers
Answer:
Differentiation of both the term is [tex]2x+3[/tex]
Step-by-step explanation:
As we have to use first principle of derivatives lets recall the formula.
[tex]f(x)= \lim_{h\to 0}\frac{(x+h)-f(x)}{h}[/tex]
Solving our eqaution.
[tex]y=x^2+3x[/tex]
We will work with [tex]f(x+h)[/tex] then [tex]-f(x)[/tex] separately then put in the above formula.
1.
[tex]f(x+h)=(x+h)^2+3(x+h)[/tex]
[tex](x^2+h^2+2hx+3x+3h)[/tex]
Now [tex]-f(x)[/tex]
[tex]-f(x)=-x^2-3x[/tex]
Plugging the values of both.
[tex]f(x)= \lim_{h\to 0}\frac{(x+h)-f(x)}{h}[/tex]
[tex]f(x)= \lim_{h\to 0}\frac{(x^2+h^2+2hx+3h+3x)- x^2-3x}{h}=\frac{h^2+2hx+3h}{h}[/tex]
Taking [tex]h[/tex] as common.
[tex]f(x)= \lim_{h\to 0}\frac{h^2+2hx+3h}{h}=h+2x+3[/tex]
Putting [tex]h=0[/tex]
Then
[tex]f(x)=2x+3[/tex] is the final derivative.
This will be same for [tex]y= x^2 + 3x + 8[/tex] as we have to put [tex]8[/tex] only.
2.
[tex]f(x+h)=(x+h)^2+3(x+h)+8[/tex]
[tex](x^2+h^2+2hx+3x+3h)[/tex]
Then [tex]-f(x)=-x^2-3x-8[/tex]
Plugging the values of both.
[tex]f(x)= \lim_{h\to 0}\frac{(x+h)-f(x)}{h}[/tex]
[tex]f(x)= \lim_{h\to 0}\frac{(x^2+h^2+2hx+3h+3x+8)- x^2-3x-8}{h}=\frac{h^2+2hx+3h}{h}[/tex]
Taking [tex]h[/tex] as common.
[tex]f(x)= \lim_{h\to 0}\frac{h^2+2hx+3h}{h}=h+2x+3[/tex]
Putting [tex]h=0[/tex]
Then
[tex]f(x)=2x+3[/tex] is the final derivative.
So both the derivatives are same.

Answers
Answer:
3/8
Step-by-step explanation:
You'd first want to count all the triangles (possibilities) which is 8 total numbers
Then find the even numbers. There is 2, 2, and 4 which is a total of 3 even numbers
The fraction would be 3/8 and it can't be simplified any further
Answer:
3/8
Step-by-step explanation:
This is because, out of 8 results, only 3 of them are even numbers. That is the biggest chance you have at getting an even number.
Quadrilateral PQRS has vertices P(2, 10), Q(6, 8), R(6, 3), and K(2, 3).
What are the coordinates of S’ after a dilation of quadrilateral PQRS by a factor of 2 centered at the origin?
Answers
Answer:
[tex]S'(4,6)[/tex]
Step-by-step explanation:
Dilation rules :
For a pre-image point [tex](x,y)[/tex] which is dilated by a scalar factor of [tex]k[/tex] about the origin, the corresponding point of the image can be given by [tex](kx,ky)[/tex]
Pre-image point [tex](x,y)\rightarrow (kx,ky)[/tex] Image point
Given points of quadrilateral PQRS.
P(2,10)
Q(6,8)
R(6,3)
S(2,3)
The quadrilateral is dilated about the origin by a scalar factor of 2.
The co-ordinates of point S' after dilation can be given by:
[tex]S(2,3)\rightarrow S'((2\times2),(2\times3))[/tex]

Can the sides of a triangle have lengths 3, 3, and 10?
Answers
Answer:
No
Step-by-step explanation:
According to the property of the triangle ,
sum of any two sides should we greater then third side of the triangle.
Here, Measurement of three sides are given as 3,3,5 .
So, sum of the measurement of first two sides is 6.
And third side equals 10.
Clearly 6 is less than 10. So . it violates the property sum of any two sides should we greater then third side of the triangle.
Thus , Sides of a triangle can't be 3,3,10.
Answer:
Yes
Step-by-step explanation:

Answers
Answer: 2b/3 (second answer choice)
======================================
Explanation:
The work shown on the screenshot basically shows plugging x = 2(a+c)/3 into the y(x) function and then simplifying. Step 5 isnt fully simplified, so let's combine like terms, factor, and then divide out a pair of (a-2c) terms to get the following:
y = (2ab+2bc-6bc)/(3(a-2c))
y = (2ab-4bc)/(3(a-2c))
y = (2b*a-2b*2c)/(3(a-2c))
y = 2b(a-2c)/(3(a-2c))
y = 2b/3
find a positive real number such that its square is equal to 15 times the number increased by 286
Answers
Answer:
The positive real number is 26
Step-by-step explanation:
Let
x ----> the number
we know that
The algebraic expression that represent this problem is
[tex]x^{2} =15x+286[/tex]
so
[tex]x^{2}-15x-286=0[/tex]
The formula to solve a quadratic equation of the form
[tex]ax^{2} +bx+c=0[/tex]
is equal to
[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]
in this problem we have
[tex]x^{2}-15x-286=0[/tex]
so
[tex]a=1\\b=-15\\c=-286[/tex]
substitute in the formula
[tex]x=\frac{-(-15)(+/-)\sqrt{-15^{2}-4(1)(-286)}} {2(1)}[/tex]
[tex]x=\frac{15(+/-)\sqrt{1,369}} {2}[/tex]
[tex]x=\frac{15(+/-)37}{2}[/tex]
[tex]x_1=\frac{15(+)37}{2}=26[/tex]
[tex]x_2=\frac{15(-)37}{2}=-11[/tex] ---> the solution cannot be negative
therefore
The positive real number is 26
A pool holds 33500 gallons of water. The pool is filled at a constant rate of 485 gallons every 6.5 minutes. Select whether each statement is true or false.
________ The unit rate for filling the pool is 74 gallons per minute
________ It will take 4 hours and 15 minutes to fill the pool to 85% of its capacity.
________ The difference between the pool being 64% full and 48% full is 3600 gallons.
________ A slow leak has left the pool with only 19800 gallons, a 12% decrease.
________ The pool can be completely filled in less than 5 hours.
Answers
1. It's True. Since it's 485 gallons every 6.5 minutes, then to find 1 minute you would do 485/6.5 which is approximately 74 gallons.
2. It's False. 85% of 33500 is 28475 gallons. If you divide that by 74, since that's the number of gallons per minute, you get approximately around 384 minutes. Since you want the time in hours, you divide 384 by 60, and you get the decimal 6.4. Since 6 hours is greater than 4 hours, it's false.
3. It's False. 64% of 33500 is 21440 gallons. 48% of 33500 is 16080 gallons. 21440-16080 is 5360 gallons, not 3360 gallons.
4. It's False. To find the percent of change, you first need to subtract 19800 from 33500, which gives you a result of 13700. Then you divide 13700/33500, which gives you a quotient of approximately 0.41. You multiply that by 100 to find the percent, which is 41%. 41% is not equal to 12%.
5. It's False. Since the unit rate is 74 gallons per minute, you divide 33500 by 74 to see how many minutes it takes. That gives you a quotient of approximately 453 minutes. You divide that by 60 since you want the time in hours, and the quotient of that is 7.55. 7 hours is greater than 5, so it's false.
I'm not too sure about some of them, so you might want to check my math. :)
Identify the transformation on the figure shown.
A) reflection over the x-axis
B) reflection over the y-axis
C) rotation about the x-axis
D) rotation about the y-axis
Answers
The transformation on the figure is a reflection over the y-axis.
How to identify the transformation?In the image, we can see that we have an original figure in the left side of the y-axis, and then it is reflected over it.
We can see that it is a reflection and not a translation, because the orientation of the figure changes (you can see that in both figures, the 90° is in the side farthest away from the axis).
So the correct option is B, reflection over the y-axis.

Answers
Answer:
The greatest number is A. 1.3 * 10⁵
Step-by-step explanation:
Let's find the greatest number:
Option A : 1.3 * 10⁵ = 1.3 * 100,000 = 130,000
Option B : 9.8 * 10² = 9.8 * 100 = 980
Option C : 9.6 * 10⁴ = 9.6 * 10,000 = 96,000
Option D : 4.6 * 10⁻⁵ = 4.6 * 0.00001 = 0.000046
130,000 > 96,000 > 980 > 0.000046
The greatest number is A. 1.3 * 10⁵
Which expression is equivalent to −13(6x+15)−3
Answers
The expression is equivalent to −78x − 198.
To simplify the expression −13(6x + 15) − 3, you can start by distributing the −13 across the terms inside the parentheses:
−13 * 6x = −78x
−13 * 15 = −195
So, the expression becomes:
−78x − 195 − 3
Next, combine the constant terms:
−195 − 3 = −198
The simplified expression is now:
−78x − 198
This expression is equivalent to the original expression −13(6x + 15) − 3. It cannot be further simplified as the terms are not like terms and cannot be combined further. So, the answer is −78x − 198.
The expression represents a linear equation where x is the variable. It can be used to find the value of the expression for specific values of x.

A line has a slope of 8 and includes the points (1, z) and (2,8). What is the value of z?
Answers
The value of z is zero

Final answer:
This answer clarifies the true statement about the division of 1.23 by 0.15, highlighting key misconceptions about the dividend, divisor, and quotient.
Explanation:
Which statement about 1.23 ÷ 0.15 is true?

Factor The Polynomial X2+X-6
Answers
Answer:
C) (x-2)(x+3)
Step-by-step explanation:
x^2+x-6=(x-2)(x+3)
Because (x-2)(x+3)=x^2-2x+3x-6=x^2+x-6.
Final answer:
The polynomial x² + x - 6 factors to (x + 3)(x - 2) by finding two numbers that multiply to -6 and add to 1.
Explanation:
To factor the polynomial x² + x - 6, one needs to find two numbers that multiply to -6 (the constant term) and add up to 1 (the coefficient of the middle term, x). These numbers are 3 and -2, because 3 × (-2) = -6, and 3 + (-2) = 1. Therefore, the factored form of the polynomial is (x + 3)(x - 2).
