Answer: 3.51%
Step-by-step explanation:
Percent error is theoretical minus experimental, divided by the theoretical, and multiplied by 100.
[tex]error=(\frac{(T-E)}{T} )*100[/tex]
[tex]error=(\frac{(17.1-16.5)}{17.1} )*100[/tex]

Discuss the process of factoring a quadratic function in standard form, y=ax^2+bx+c, as well as using the example y=3x^2+10x+8.
Answer:
y=(3x+4)(x+2)
Step-by-step explanation:
Once you distibute everything you will get:
3x^2
6x

Answer:
(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);
Step-by-step explanation:
formula to find area is L* W = A ; meaning length multiplied by width equals to the area.
21.
using the formula to find area...
l*w=a
(7x+2)(3x-1) would be your answer
btw, don't put the "=a" at the end, since it's an expression :))
22.
since the problem states that it's a square, you can just say either...
(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts
Thanks, brainliest, and 5 stars!!

Need help ASAP BC it’s too hard for me
Answer:
1=3
Step-by-step explanation:
Subtract the number without the x from the answer then find a multiple of the number with the x for example
5x+2=17
17-2=15
Multiples
X1= 5
X2=10
X3= 15
Answer:
I hope this helps :)
Step-by-step explanation:
- 5x + 2 = 17 -- x = 3
- 3x + 5 = 36 -- x = 10.333
- x/3 - 14 = 9 -- x = 7.667 (Might be wrong)
- 73 = 3x - 20 -- x = 31
- 2x - 14 = 7 -- x = 10.5
- 53 = 9x - 1 -- x = 6
1 how many more calories should a person on a 2,000-calorie diet eat from veggies than from carbs?
2 if a person is on an 1,800-calorie diet,then how many of their calries will come from fruit?
3 a person on a 2500 calorie diet states that they ar healthier because they eat more calories from veggies. explain why this is or is not accurate
4 according to the graph above which of the following best represents the number of calories from protein a person on a 2200 calorie diet should consume
A 450
B 550
C 625
D 650
The calories from the different diets are given below.
1. 2,000 calories diet eat from veggies than from carbs is 200 calories.
2. 1,800 calories diet from fruit is 270 calories.
3. 2500 calorie diet, healthier because they eat more calories is not accurate.
4. 2200 calorie diet eat from protein is 550 calories. Then option B is correct.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
1. The calories should a person on a 2,000 calories diet eat from veggies than from carbs will be
→ 2000 × 0.35 = 700 calories
→ 2000 × 0.25 = 500 calories
→700 – 500 = 200 calories
2. If a person is on a 1,800 calories diet, then the calories will come from fruit will be
→ 1800 × 0.15 = 270 calories
3. A person on a 2500 calorie diet states that they are healthier because they eat more calories from veggies will be
→ 2500 × 0.35 = 875 calories
Because veggies have more calories than others. Thus, inaccurate.
4. The number of calories from protein a person on a 2200 calorie diet should consume will be
→ 2200 × 0.25 = 550 calories

Tell whether each number is a solution to the problem modeled by the following equation.
Mystery Number: Five more than −8 times a number is 29. What is the number?
Let the mystery number be represented by n. The equation is 5+(−8)n = 29.
Is 3 a solution to the equation?
Is −4 a solution to the equation?
Answer:
Neither are a solution.
Step-by-step explanation:
The thing is, -4 * -8= 32+5 =37, and you're looking for 29.
3*-8=-24+5=19. If you meant to put positive 8 and not negative, then 3 would be right, but other than that, neither are correct.

A student usually saves $20 a month. He would like to reach a goal of saving $350 in
12 months. The student writes the equation 12(x + 20) = 350 to represent this situation.
Solve the equation for x.
• Show your work or explain your answer.
• Write your answer as a sentence that describes what the variable x represents
Answer:
Step-by-step explanation:
12x + 240 = 350
12x = 110
x = [tex]\frac{110}{12}[/tex]
x is how much money the student needs to save more amonth. so insead of saving 20 dollars the student would have to save 20+x dollars and x is [tex]9.16666666666.....[/tex]

the vertices of △ABC are A(-5,4),B(-2,4),and C(-4,2). If ABC is reflected across the y-axis to produce the image △ABC, find the coordinates of the vertex C
the coordinates of C are...
Answer:
(4, 2)
Step-by-step explanation:
Because ABC is reflected across the y-axis, this means that the y coordinate will remain the same, and the x coordinate is the negative of its original (because it is being flipped)
If the vertices of △ABC are A(-5,4),B(-2,4),and C(-4,2). If ABC is reflected across the y-axis to produce the image △ABC, then coordinates of the vertex C is (4,2)
What is coordinate system?
a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other.
Given that,
Vertices of △ABC are A(-5,4),B(-2,4),and C(-4,2).
If ABC is reflected across the y-axis to produce the image △ABC.
We need to find the image of △ABC.
We need to find coordinates of vertex C.
As ABC is reflected across the y-axis, this means that the y coordinate will remain the same,
As the triangle is flipped the sign of x coordinate is the negative of its original.
Hence (4,2) is the coordinates of the vertex C.
