<=> 2x = -8

<=> x = -4

with x = -4 => HI = - 4 + 12 = 8

Step-by-step explanation:

Answer:

Step-by-step explanation:

20 = 12 + 16 + 2x

20 - 12 - 16 = 2x

-8 = 2x

x = -4

Solve for h in terms of g and u


4u²(2u²) /g = -2u²h -gh²/2 +h

Answers

9514 1404 393

Answer:

  h = (1 -2u² ± √(1 -4u²-12u⁴))/g

Step-by-step explanation:

This is a quadratic in h, so there are two solutions.

Written in standard form, the given equation is ...

  (-g/2)h² +(1-2u²)h -8u⁴/g = 0

The quadratic formula tells you the solution for h is ...

  h = (-(1 -2u²) ±√((1 -2u²) -4(-g/2)(-8u⁴/g)))/(2(-g/2))

  h = (2u² -1 ± √(4u⁴ -4u² +1 -16u⁴))/-g . . . . . simplify

  h = (1 -2u² ± √(1 -4u²-12u⁴))/g . . . . . . . . collect terms

Which equation reveals the minimum or the maximum value of f(x) without changing the form of the equation?

A f(x) = (x – 1)2 + 2

6 f(x) = x2 – 2 – x + 1

© f(x) = x2 – 2x + 1

D f(x)= (x - 1)(x - 1)

Answers

Answer:

A): f(x) = (x – 1)² + 2

Step-by-step explanation:

The quadratic function, f(x) = (x – 1)² + 2 is in vertex form: y = a(x - h)² + k, where:

The vertex of the graph is (h,k).The value of a determines whether the graph opens up or down. If a is positive, the graph opens up and the vertex is its minimum point. If a is negative, then the graph opens down, and the vertex is its maximum point. The value of h determines how far left or right the parent function is translated. The value of k determines how far up or down the parent function is translated.

The function, f(x) = (x – 1)² + 2, provides the pertinent information that allows us to determine the parabola's minimum value, as the value of a is a positive, which implies that the parabola is upward facing, and the vertex, (1, 2) is the minimum point.

A passenger train leaves the train depot 2 hours after a freight train left the same depot. The freight train is traveling 20mph slower than the passenger train. Find the rate of each train, if the passenger train overtakes the freight train in threehours.

Answers

Answer:

50 (mph)    = rate of passenger train

Step-by-step explanation:

Let the rate of  the freight train  =   R

Let the rate of the  passenger train  be R +  30

The freight train  has  been  traveling for 2 + 3   =  5 hours

And the passenger train has  been traveling for  3 hours

And they  have traveled the same distance   when  the passenger  train  overtakes the freight train

So    using rate * time  = distance we have that

R(5)  = (R + 20) 3      simplify

5R  =  3R  +  60     subtract 3R from  both sides

2R  = 60           divide  both sides  by  2

R = 30   (mph)  = rate of freight train

R +  20  =  50 (mph)    = rate of passenger train

The perimeter of a rectangle is 28cm it’s length is more than 10cm more than it’s widith which equation can be used to find the dimensions

Answers

P = 2((10 + x) + x)

The perimeter of a rectangle is the sum of the length and width multiplied by 2

P = 2(l + w)

[to simplify the expression]

P = 2 × (l + w)

[using x to represent the width]

w = x

l = x + 10

P = 2 × ((10 + x) + x)

P = 2((10 + x) + x)

1. X = 170-80-80 = 20

2. X = 180-75-75 = 30

3. X = 180-70 = 110/2 = 55

Step-by-step explanation:

1) x+80°+80°=180°

x=180°-160°

x=20°.

2) as it is a isosceles triangle, y =75°.

x+75°+75°=180°

x=180°-150°

x=30°.

3) 2x+70°=180°

2x=110°

x=55°.
