Answer:
Jeremy has 5 1/4 cups of all purpose flour after preparing his recipe.
Step-by-step explanation:
Since the recipe for whole wheat pizza crust calls for 1 1/2 cups of all purpose flour, 1.5 cups of that product is required to create the meal in question.
Now, since Jeremy has 5 7/4 of all purpose flour, it can be stated that he has 6.75 cups of it (7/4 = 1.75).
Therefore, to determine the amount of flour that Jeremy will have left over after preparing the recipe, it is necessary to perform the following calculation:
6.75 - 1.5 = X
5.25 = X
So since 0.25 is equal to 1/4, Jeremy has 5 1/4 cups of all purpose flour after preparing his recipe.
3y(2y+5) solve the problem
3y×(2y+5)
Multiply each term in the parentheses by 3y
3y×2y+3y×5
Calculate the product
6y²+3y×5
Now we do the same thing only different way
3y×2y
Multiply the numbers
6y×y
If a term doesn't have an exponent , it is considered that the exponent is 1
6y^1×y^1
Multiply the terms with the same base by adding their exponents
6y^1+1
add the numbers
6y²
6y^2+3y×5×
calculate the product
6y²+15y
It's the same thing only different way ok
3y×5
Multiply the numbers
15y
answer: 6y²+15y

Which table of values could be generated by the equation -10x+5y=15
9514 1404 393
Answer:
see below
Step-by-step explanation:
I find it convenient to factor 5 from the equation and re-order the left side:
y -2x = 3
This makes it relatively easy to see that the values in the left-most table will satisfy this equation.
__
If we look at the table values for x=2, where all the tables differ, we can easily find the one that works:
1. 7 -2(2) = 3 . . . . this value works in the equation
2. 0.5 -2(2) = -3.5 . . . . no
3. -1 -2(2) = -5 . . . . no
4. 2.5 -2(2) = -1.5 . . . . no

Zoey had 3/4 of a pizza left after going to a local restaurant last night. Today she eats 1/3 of the remaining pizza for lunch. How much of the original pizza does Zoey have left now?
Answer:
half of the pizza is left
Step-by-step explanation:
1 ) three quarters are left = 75% of the original pizza
2) she eats one third of the pizza = 1/3 of 75
3) one third of the pizza is 25 %
4) 75-25 = 50
5) 50 is half of the pizza

Using the paths shown, the distance from Brookfield to Seaside is 20.4 kilometers.
How far is it from Brookfield to Yardley?
Answer:
7.2 km
Step-by-step explanation:
Distance between Brookfield to Seaside = 20.4 km
Distance between Yardley and Seaside = 13.2 km
Let distance between Brookfield to Yardley be x.
Thus:
x + 13.2 km = 20.4 km
Subtract 13.2 from each side
x = 20.4 - 13.2
x = 7.2
Distance from Brookfield to Yardley is 7.2 km

They suggest that the audience has listened to and understood all of Truth’s reasons.
They inform the audience that Truth will not give another speech about women’s suffrage.
They encourage the audience to question Truth’s reasoning and the ideas she has put forth.
Answer:
They suggest that the audience has listened to and understood all of Truth’s reasons.
Step-by-step explanation:
Obliged to you for hearing me, and now old Sojourner ain’t got nothing more to say.
This Implies that she needs to say nothing more, because the truth was so blaringly obvious that everyone in the crowd understood it. It also implies that no better argument for her cause could be put forward, and none was needed.
The statement that most adequately recounts the impact of the given words is: Option A: They remind the audience that Truth has had rich life experiences and offers valuable wisdom.
Effect of WordsFrom the story of "Ain't I a Woman?", we can see that Sojourner is a strong-headed woman that had gone through serious battles all her life in seeking equal rights of women.
Now, the last sentence from "Ain't I a Woman" given in the question exists to help tell the reader that Truth had encountered standard experiences in his life and as such it promotes useful understanding and ideas.Finally, words used like "obliged" and "old" are descriptive words that help show us that she is a humble, and experienced person.
In conclusion, the correct answer is Option A.

1. A wave has a wavelength of 5 m and a frequency of 2 Hz. At what speed/velocity does the
wave travel?
2. The speed/velocity of a wave on a guitar string is 100m/s and the frequency is 1,000 Hz. What
is the wavelength of the wave?
3. If the speed/velocity of a wave is 25 m/s and the wavelength is 5 m, what is the frequency of
this wave?
We will be using the formula: Speed = Wavelength * Frequency
1. Given: Wavelength = 5 m and Frequency = 2 Hz
Speed of the wave = Wavelength * Frequency
Speed of the wave = 5 * 2
Speed of the wave = 10 m/s
__________________________________________________________
2. Given: Speed of the wave = 100 m/s and Frequency= 1000 Hz
Wavelength = Speed / Frequency
Wavelength = 100 / 1000
Wavelength = 0.1 m
__________________________________________________________
3. Given: Speed of the Wave = 25 m/s Wavelength = 5 m
Frequency = Speed / Wavelength
Frequency = 25 / 5
Frequency = 5 Hz

Find the 2nd Derivative:
f(x) = 3x⁴ + 2x² - 8x + 4
Answer:
[tex]f''(x)=36x^2+4[/tex]
Step-by-step explanation:
Let's start by finding the first derivative of [tex]f(x)= 3x^4+2x^2-8x+4[/tex]. We can do so by using the power rule for derivatives.
The power rule states that:
[tex]\frac{d}{dx} (x^n) = n \times x^n^-^1[/tex]This means that if you are taking the derivative of a function with powers, you can bring the power down and multiply it with the coefficient, then reduce the power by 1.
Another rule that we need to note is that the derivative of a constant is 0.
Let's apply the power rule to the function f(x).
[tex]\frac{d}{dx} (3x^4+2x^2-8x+4)[/tex]Bring the exponent down and multiply it with the coefficient. Then, reduce the power by 1.
[tex]\frac{d}{dx} (3x^4+2x^2-8x+4) = ((4)3x^4^-^1+(2)2x^2^-^1-(1)8x^1^-^1+(0)4)[/tex]Simplify the equation.
[tex]\frac{d}{dx} (3x^4+2x^2-8x+4) = (12x^3+4x^1-8x^0+0)[/tex] [tex]\frac{d}{dx} (3x^4+2x^2-8x+4) = (12x^3+4x-8(1)+0)[/tex] [tex]\frac{d}{dx} (3x^4+2x^2-8x+4) = (12x^3+4x-8)[/tex][tex]f'(x)=12x^3+4x-8[/tex]Now, this is only the first derivative of the function f(x). Let's find the second derivative by applying the power rule once again, but this time to the first derivative, f'(x).
[tex]\frac{d}{d} (f'x) = \frac{d}{dx} (12x^3+4x-8)[/tex] [tex]\frac{d}{dx} (12x^3+4x-8) = ((3)12x^3^-^1 + (1)4x^1^-^1 - (0)8)[/tex]Simplify the equation.
[tex]\frac{d}{dx} (12x^3+4x-8) = (36x^2 + 4x^0 - 0)[/tex] [tex]\frac{d}{dx} (12x^3+4x-8) = (36x^2 + 4(1) - 0)[/tex] [tex]\frac{d}{dx} (12x^3+4x-8) = (36x^2 + 4 )[/tex]Therefore, this is the 2nd derivative of the function f(x).
We can say that: [tex]f''(x)=36x^2+4[/tex]
Answer:
[tex]y = f(x) = 3 {x}^{4} + 2 {x}^{2} - 8x + 4 \\ \frac{dy}{dx} = 12 {x}^{3} + 4x - 8 \\ \frac{d {}^{2} y}{dx {}^{2} } = 36 {x}^{2} + 4 \\ \boxed{\frac{d {}^{2} y}{dx {}^{2} } = 4(9 {x}^{2} + 1)}[/tex]

Answer:
The missing value in the ordered pair is 6.
Step-by-step explanation:
Given that:
The ordered pairs are (-1, 3) and (x,-7)
We have to find the missing value x so that the ordered pairs have a slope -2.
Slope is the steepness of a line which is denoted by m.
Slope =m= -2
Here,
[tex]x_1=-1, y_1=3\\\\x_2=x, y_2=-7[/tex]
Slope is given by;
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Putting the given values,
[tex]-2=\frac{-7-3}{x-(-1)}\\-2=\frac{-10}{x+1}\\-2(x+1)=-10\\-2x-2=-10\\-2x=-10-2\\-2x=-12[/tex]
Dividing both sides by -2
[tex]\frac{-2x}{-2}=\frac{-12}{-2}\\x=6[/tex]
Hence,
The missing value in the ordered pair is 6.
An unconfined compression test was performed to determine the average strength of concrete cylinders (in psi). It is believed that the strength is approximately normally distributed with a standard deviation of 256 psi. A sample of 70 concrete cylinders was taken, and it was found that the average strength was 3000 psi. Find a 91% confidence interval for the true average strength of the concrete.
Be sure to:
• State the value for α.
• State whether you should use z or t and find the appropriate value. Round z-values to 2 decimals. Round t-values to 3 decimals.
• Find the confidence interval (to 2 decimals). State the parameter your confidence interval is for.
• Write a verbal interpretation of your confidence interval.
Answer:
Explained below.
Step-by-step explanation:
(1)
The confidence level is, 91%.
Compute the value of α as follows:
[tex]\text{Confidence level}\% =(100-\alpha \%)\\\\91% = 100-\alpha \%\\\\\alpha \%=100-91\%\\\\\alpha \%=9\%\\\\\alpha =0.09[/tex]
(2)
As the population standard deviation is provided, i.e. σ = 256 psi, the z value would be appropriate.
The z value for α = 0.09 is,
z = 1.69
(3)
Compute the 91% confidence interval as follows:
[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]
[tex]=3000\pm 1.69\cdot\frac{256}{\sqrt{70}}\\\\=3000\pm 51.71\\\\=(2942.29, 3057.71)[/tex]
(4)
The 91% confidence interval for population mean implies that there is a 0.91 probability that the true value of the mean is included in the interval, (2942.29, 3057.71) psi.
