When 5x^2 + 2= 4x is written in standard form, what are the values of a, b, and c
goblinko [34]

The standard form of a quadratic equation is

ax^{2}+bx+c=0,

where a, b, and c are coefficients. You want to get the given equation into this form. You can accomplish this by putting all the non-zero values on the left side on the equation.

In this case, the given equation is

5x^{2}+2=4x

Since 4x is on the right side of the equation, we subtract that from both sides. The resulting equation is

5x^{2}-4x+2=0

Looking at the standard form equation ax^{2}+bx+c=0, we can see that

a=5, b=-4, c=0

100 points I have answer. Can someone explain this correct answer, I know its correct, but need to understand why? Do we subtrac
lapo4ka [179]

Answer:

c = -6

d = 2

Step-by-step explanation:

After reflection about the x-axis:

A --> A'

(2,3) --> (2,-3)

(4,3) --> (4,-3)

(2,6) --> (2,-6)

After translation:

(2 + c, -6 + d) --> (-4, -4)

2+c = -4

c = -6

-6+d = -4

d = 2

Explain how you can find the volume of the figure below. Then, solve- what is the volume of the figure? Make sure to include you
mote1985 [20]

Answer: a) The figure can be reasonably divided into two geometries:

• a rectangular prism

• a hemisphere.

b) The volume of the rectangular prism is given by

  V = lwh

  V = (10 cm)(5 cm)(4 cm) = 200 cm³

The volume of the hemisphere is given by

  V = (2π/3)r³

  V = (2π/3)(3 cm)³ = 18π cm³

c) The total volume of the figure is

  total volume = (prism volume) + (hemisphere volume)

  V = 200 cm³ + 18π cm³

  V ≈ 256.549 cm³

Easy points
goblinko [34]

Answer: 2

Step-by-step explanation:

try each value in the equation

2(0) + 1 = 3

0 + 1 = 3

1 ≠ 3

so 0 doesn’t work

2(1) + 1 = 3

2 + 1 = 3

3 = 3

this works, so the answer is 1

A water balloon is tossed into the air with an upward velocity of 40 ft/sits height h(t) in ft after t seconds is given by the f
olga_2 [115]

h(t) = -46t² + 40t + 3

We can think this graph by t being the x-axis and h being y-axis

So we want the maximum value to y.

We know by math that the vertex of a parabola is (-b/2a, -Δ/4a)

So the y value of the vertex is -Δ/4a

Let's calculate:

Δ = b² - 4.a.c

Δ = 40² - 4.(-46).3

Δ = 2152

Yvertex = -2152/4.(-46)

Yvertex = 2152/184

Yvertex = 269/23

Now we have the value of y we need to equal it to the equation

269/23 = -46t² + 40t + 3

-46t² + 40t + 3 - 269/23 = 0

-46t² + 40t - 200/23 = 0

Δ = b² - 4.a.c  

Δ = 40² - 4 . -46 . (-200/23)  

Δ = 1600 - 4. -46 . (-200/23)  

Δ = 0

There's 1 real root.

In this case, x' = x'':

x = (-b +- √Δ)/2a

x' = (-40 + √0)/2.-46    

x'' = (-40 - √0)/2.-46

x' = -40 / -92    

x'' = -40 / -92

x' = 0,43478260869565216    

x'' = 0,43478260869565216

So, after approximately 0,4348 seconds the balloon will reach the highest point.

B) height after 2 seconds

h(2) = -46.2² + 40.2 + 3

h(2) = -46.4 + 80 + 3

h(2) = -184 + 83

h(2) = -101

Not sure how it's possible but it would be -101.
