The x-coordinate of the vertex of the function y=-x²+bx+3 is 10. Determine the y-coordinate of the vertex.
Answers
Answer:
103Step-by-step explanation:
Given function:
y = -x² + bx + 3The x-coordinate of a quadratic function y = ax² + bx + c is determined by:
x = -b/2aThe given function has:
x = 10, and a = -1Find the value of b:
10 = -b / -2b = 20The function is:
y = -x² + 20x + 3The y-coordinate of the vertex is:
y = -(10²) + 20*10 + 3 = -100 + 200 + 3 = 103Answer:
Solution given:
y = -x² + bx + 3
we have
The x-coordinate of a quadratic function y = ax² + bx + c is determined by:
x = [tex] \frac{ - b}{2a} [/tex]
we have
x = 10, and a = -1
Substituting value of a in -b/2a
we get
b = 20
now
The y-coordinate of the vertex is:
y = -(10²) +20*10+ 3 = -100 + 200 + 3 = 103 is your answer.

Answer:
x ≈ 47°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinx° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{8}{11}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{8}{11}[/tex] ) ≈ 47° ( to the nearest degree )
Describe how you would determine whether a triangle is a right triangle given its coordinates.
A. You could find out whether the slopes of any two sides have a product of −1. B. You could find out whether any two sides have the same slope. C. You could find out whether one side is parallel to an axis, or perpendicular to an axis. D. You could find out whether one side has a slope of 0, and another side has a slope of either 1 or −1.

Originally, a department store bought a set of dishes at a cost of $57.68 and marked it up 125%. After a month, the set of dishes had not sold, so the store marked it down 50%. What was the discounted price?
Answers
Answer:
$64.89
Step-by-step explanation:
57.68 + 1.25 × 57.68
= 57.68 + 72.1
= 129.78
The original price was $129.78.
129.78 – 0.50 × 129.78
= 129.78 – 64.89
= 64.89
The discount price was $64.89.

Step-by-step explanation:
An unknown number y is 15 more than an unknown number x. The number y is also x less than 8. The equations to find x and y are shown below.
y = x + 15
y = −x + 8
Which of the following statements is a correct step to find x and y?
and could somebody please give me a step by step explanation
Answers
Next you need to move both variables to the same side so you can subtract x from both sides so it would be 15=-2x+8
Now you want to get the variable alone so you’d subtract the 8 from each side of the equation and you’d be left with 7=-2X
Lastly you one just one x so divide each side by -2 and you’d have 7/-2=x
x= -7/2 or -3.5
Let me know if you want further explanation of how I got x.
Answer:
x = −3.5
y = 11.5
Step-by-step explanation:
y = x + 15
y = −x + 8
[We know that y is 15 units more than x, and that −x is 8 units less than y. That can be combined into −x + 8 = x + 15 for the first variable (x), and for the second variable (y), y − 15 = −y + 8]
↓
In order to solve this, solve for the first variable in one of the equations, then substitute the result into the other equation.
↓
x = −[tex]\frac{7}{2}[/tex] = −3.5
y = [tex]\frac{23}{2}[/tex] = 11.5

games in 75% of the seasons that they played.
Answers
Answer:
Ronique's team won at least 24 games in 75% of the season that they played.
Step-by-step explanation:
(The box-whisker plot below will show everything, but I'll explain it in detail because I want to be more helpful)
So... we have seven data points.
2014 - 15 (Year 1): 31 wins
2015 - 16 (Year 2): 24 wins
2016 - 17 (Year 3): 32 wins
2017 - 18 (Year 4): 22 wins
2018 - 19 (Year 5): 34 wins
2019 - 20 (Year 6): 28 wins
2020 - 21 (Year 7): 38 wins
We need a box & whisker plot for this.
22 will go on the left whisker, since it's the lowest of the data points. 38 will go on the right whisker, since it's the highest.
For the two quartiles, 24 is the first quartile, so from that point to the right whisker, that's 75% of the data. The third quartile will be 34. And the midline will be at 31, since it's the median of the data points.
From that explanation, we can be sure that Ronique's team won at least 24 games in 75% of the seasons that they played.
