DOES ANYONE UNDERSTAND QUADRATIC APPLICATIONS FOR ALGEBRA 1???? PLS DONT RESOND IF YOU DINT KNOW

Mathematics
1 answer:
lilavasa [31]2 years ago

Answer:

1 ) Vertex form.

2 ) Standard form.

3 ) I'm not sure about this one, but there are only 3 forms, in which the last one is factored form, and the other two are above, so it must be factored form.

Step-by-step explanation:

1 ) Vertex form : y = a( x - h )² + k

Vertex form shows you where the vertex(the lowest/highest point aka ( h, k ) ) of the parabola is, without graphing it. (But you could graph it and find the vertex like that, I recommend you use desmos graphing)

2 )Standard form : y = ax² + bx + c

Standard form can be used to show the y-intercept( aka c ), in this case, where the snowball was thrown from. (Again, you can graph it and find where he parabola hits the y axis)

3 ) Factored form : ( ax + c )( bx + d )

Factored form tells us the x-intercepts, or in this case where the snowball landed or how long the snowball is in the air. (like i said, you could graph it, and find the points(there could be only one or maybe none in some cases) that are on the x axis)

I know this was four days ago, but I hope this helped you understand a little better.

1/5x - 2/3y = 30 , when y = 15
Helga [31]

Question

1/5x - 2/3y = 30 , when y = 15


Answer:

<h2>200</h2>

Step-by-step explanation:

replace y with 15

1/5x - 2/3 * 15 = 30

1/5x - 10 = 30

1/5x = 40

x = 40 * 5

x = 200

Explain by step by step pls :( if u type something wrong ill report u
Serhud [2]

Answer:

∠ C = ∠BCD = 30°

Step-by-step explanation:

∠ EDF = ∠GFC  = 110°                [ corresponding angles ]

Now consider triangle BCF

∠FBC  + ∠ABC = 180°                [ straight line angle ]

∠FBC  + 100° = 180°

∠FBC  = 180 - 100 = 80°

∠BFC + ∠GFC = 180°                  [ straight line angle ]

∠BFC + 110° = 180°

∠BFC = 180 - 110 = 70°

Sum of angles of triangle is 180°

Therefore , in triangle BCF

That is ,

       ∠F + ∠B + ∠ C  = 180°

          70° + 80° + ∠C = 180°

           ∠C = 180 - 150 = 30°

PLEASE HELP! The trail around Mirror Lake in Yosemite National park is 5 miles long. What fraction describes how much more of th
Katen [24]

Answer:

  • Jon - Andrea = 1/10
  • Callie - Jon = 3/10

Step-by-step explanation:

In terms of tenths, the distances each hiked are ...

  • Andrea — 4/10
  • Jon — 5/10
  • Callie — 8/10

Then the differences of interest are ...

  Jon - Andrea = 5/10 -4/10 = 1/10

  Callie - Jon = 8/10 - 5/10 = 3/10

__

Jon hiked 1/10 of the trail more than Andrea.

Callie hiked 3/10 of the trail more than Jon.

What is 2.24 rounded to the nearest tenth?
quester [9]
One tenth is 0.1.  Therefore, the answer has to be 2.x.  Since 4 is less than 5, the 2 remains the same.  The answer is 2.2.
