Answer:
x=14.28
Step-by-step explanation:
24^2+x^2=28^2, Pythagorean theorem
x^2=28^2-24^2
x^2=(28+24)(28-24)
x^2=52*4
x^2=204
x is around 14.28

A square has a perimeter of 12x^4 + 36x^3 inches. What is the length of each side?
Answer:
3x^4+9x^3
Step-by-step explanation:
Perimeter of a square is expressed as;
P = 4L
L is the length of each side
Given
P = 12x^4 + 36x^3
12x^4 + 36x^3 = 4L
4(3x^4+9x^3) = 4L
Divide both sides by 4
4(3x^4+9x^3)/4 = 4L/4
(3x^4+9x^3) = L
L = 3x^4+9x^3
Hence the length of each side is 3x^4+9x^3

(3x2 7x + 14) + (5x2 + 41 6) is equivalent to expression
(2x2 – 5x – 3) + (-10x2 + 2x + 7) is equivalent to expression
(12t2 – 2x – 13) + (-4x2 + 5x + 9) is equivalent to expression
Answer/Step-by-step explanation:
✔️(3x² - 7x + 14) + (5x² + 4x - 6)
3x² - 7x + 14 + 5x² + 4x - 6 (distributive property)
Add like terms
3x² + 5x² - 7x + 4x + 14 - 6
8x² - 3x + 8
Therefore:
✅(3x² - 7x + 14) + (5x² + 4x - 6) is equivalent to expression 8x² - 3x + 8.
✔️(2x² - 5x - 3) + (-10x² + 2x + 7)
2x² - 5x - 3 - 10x² + 2x + 7 (distributive property)
Add like terms
2x² - 10x² - 5x + 2x - 3 + 7
-8x² - 3x + 4
Therefore:
✅(2x² - 5x - 3) + (-10x² + 2x + 7) is equivalent expression to -8x² - 3x + 4
✔️(12x² - 2x - 13) + (-4x² + 5x + 9)
12x² - 2x - 13 - 4x² + 5x + 9
12x² - 4x² - 2x + 5x - 13 + 9
8x² + 3x - 4
Therefore:
✅(12x² - 2x - 13) + (-4x² + 5x + 9) is equivalent expression to 8x² + 3x - 4

Which shows the equation below written in the form ax^2+bx+c=0. x+9=4(x-1)^2
Answer:
[tex]4x^2 - 9x - 5 = 0[/tex]
Step-by-step explanation:
To place the equation in standard form, we expand the operations. So
[tex]4(x-1)^2 = x + 9[/tex]
[tex]4(x^2-2x+1) = x + 9[/tex]
[tex]4x^2 - 8x + 4 - x - 9 = 0[/tex]
Combining the like terms:
[tex]4x^2 - 9x - 5 = 0[/tex]
Suppose John is a high school statistics teacher who believes that watching many hours of TV leads to lower test scores. Immediately after giving the most recent test, he surveyed each of the 24 students in his class and asked them how many hours of TV they watched that week. He then matched each student's test grade with his or her survey response. After compiling the data, he used hours of TV watched to predict each student's test score.

This question is incomplete, the complete question is;
Suppose John is a high school statistics teacher who believes that watching many hours of TV leads to lower test scores. Immediately after giving the most recent test, he surveyed each of the 24 students in his class and asked them how many hours of TV they watched that week. He then matched each student's test grade with his or her survey response. After compiling the data, he used hours of TV watched to predict each student's test score. He found the least-squares regression line to be y" = -1.5x + 85.
He also calculated that the value of r, the correlation, was -0.61.
what is the correct value of the coefficient of determination R² and give a correct interpretation of its meaning
Answer:
Interpretation of coefficient of determination R² = 0.3721
R² = 0.3721, meaning 37.21% of the total variation in test scores can be explained by the least square regression line
Step-by-step explanation:
Given the data in the question;
the least square regression line is;
y" = -1.5x + 85
the correlation coefficient r = -0.61
Now, the coefficient of determination R² is square of correlation coefficient r
R² = -61²
R² = 0.3721

Answer:
Nathan must order 21 sets of forks for the restaurant.
Step-by-step explanation:
Since Nathan needs to order some new supplies for the restaurant where he works, and the restaurant needs at least 571 forks since there are currently 361 forks, if each set on sale contains 10 forks, to determine the number of sets to buy you must perform the following calculation:
(571 - 361) / 10 = X
210/10 = X
21 = X
So Nathan must order 21 sets of forks for the restaurant.
