A
9, 40, 41
B
8, 30, 31
С
7.8, 15
D
2, 3, 6
Answer:
A and B are correct, but A is most correct.
Step-by-step explanation:
just do Pythagorean theorem and see which numbers add up to each other. if you do them for all 4 answers, you see d and c do not equal to each other. b is almost correct, and a comes out exact.

the path of a toy rocket is modelled by the equation y=-x^2+6x+2, where x is the horizontal distance, in metres, travelled and y is the height, in metres, of the toy rocket above the ground. what is the maximum height of the toy rocket? at what horizontal distance does the maximum height occur?
Answer:
The path of a toy rocket is defined by the relation y=-3x^2+11x+4, where x is the horizontal distance, in meters, traveled and y is the height, in metres, above the ground.
Determine the zeros of the relation.
-3x^2 + 11x + 4 = 0
---
3x^2 - 11x -4 = 0
Factor:
3x^2 - 12x + x - 4 = 0
---
3x(x-4) + x-4 = 0
---
(x-4)(3x+1) = 0
---
x = 4 or x = -1/3
============================
f(x) = -3x^2+11x+4
How far has the rocket traveled horizontally when it lands on the ground?
4 ft.
==================
What is the maximum height of the rocket above the ground, to the nearest hundredth of a meter?
---
max occurs when x = -b/2a = -11/(2*-3) = 11/6
height = f(11/6) = 14.083 ft

A coin collection contains d dimes and q quarters worth a total of $50.
Which equation models this information?
d + q = 50
10d + 25q = 50
0.1d + 0.25q = 50
0.01d + 0.25q = 50
Answer:
0.1d + 0.25q = 50
Step-by-step explanation:
dimes are worth 10 cents so it's 0.1 and d represents the unknown amount
quarters are worth 25 cents so it's 0.25 and q represents the unknown amount

How do I simplify this complex rational expression?
Answer:
[tex]\frac{23x+3}{20(x+1)}[/tex]
Step-by-step explanation:
Separate the fractions into a more readable format.
Factorise the denominators of all the fractions where possible. For [tex]x^2-1[/tex] apply DOTS ==> Difference of two squares*
Simplify the fractions.
I wrote out my working so I hope that helps :>>
*Difference of two squares is a method of factorising the sum of two squares, where one of them is negative. [tex]a^2-b^2 = (a-b)(a+b)[/tex]

Step-by-step explanation:
5x +2y=-9
3x+4y= -11
por el método de igualacion porfavor hacerlo en folio y me mandáis una foto si no no entiendo
Answer:
x = -1
y = -2
Step-by-step explanation:
5x + 2y = -9 2y = -9 - 5x y=(-9-5x)/2
3x + 4y = -11
3x+4[(-9-5x)/2] = -11
3x+( -36-20x)/2 = -11
3x-18-10x = -11
-7x = 7
x = -1
y = -2
Answer:
x = −1 and y = −2

In a basketball game Elena scored twice as many points as Tyler Tyler scores four points fewer than Noah and Noah scores three points as Mai of Mai scores 5 points how many points did Elena score
Full question:
In a basketball game, Elena scores twice as many points as Tyler. Tyler scores four points fewer than Noah, and Noah scores three times as many points as Mai. If Mai scores 5 points, how many points did Elena score? Explain your reasoning
Answer and explanation:
We start from known to unknown. We know that Mai scored 5 points and so we work from here.
Since Mai scored 5 points and Noah scored three times as many points then Noah's score = 3×5= 15 points
Since Tyler scored four points less than Noah, Noah's score= 15-4= 11 points
Finally Elena's score is twice that of Tyler hence Elena's score =2×11= 22 points

The masses of four vehicles and the net forces acting on them as they enter a highway are recorded in the table below. Vehicle Mass (kg) Force (N) Sedan 1400 5250 SUV 1900 5250 Truck 2100 5250 RV 2500 5250 Which vehicle has the greatest acceleration as it enters the highway?
Answer:
if you use Newton's 2nd rule:
F = m* a (force = mass * acceleration)
you can rearrange the terms to:
a = F/m (acceleration = Force/mass)
which will let you solve for acceleration.
use substitution to solve this. substitute for x, not y
