Question 1
What is the axis of symmetry to the following:
f(x) = x² + 2x – 8

Answers

Answer 1

Answer: x = -1

Step-by-step explanation:

Answer 2

Answer:

x = - 1

Step-by-step explanation:

Given a parabola in standard form , f(x) = ax² + bx +c ( a ≠ 0 )

Then the axis of symmetry is calculated using

x = - [tex]\frac{b}{2a}[/tex]

f(x) = x² + 2x - 8 ← is in standard form

with a = 1 and b = 2 , then axis of symmetry is

x = - [tex]\frac{2}{2}[/tex] = - 1, that is

x = - 1

Sean has 9 liters of juice. He pours equal amounts of the juice into 4 pitchers. There is 0.5 of a liter of juice left. How many liters of juice are in each pitcher? Sean has 9 liters of juice. He pours equal amounts of the juice into 4 pitchers. There is 0.5 of a liter of juice left. How many liters of juice are in each pitcher?

Answers

Answer:

2.125 liters of juice

Step-by-step explanation:

Total liters of juice = 9

Total liters left = 0.5

Total liters used = Total liters of juice - Total liters left

= 9 - 0.5

= 8.5

Total liters used = 8.5 liters

He pours equal amounts of the juice into 4 pitcher

Liters per pitcher = Total liters used / number of pitchers

= 8.5 / 4

= 2.125 liters

Liters per pitcher = 2.125 liters

Each pitcher has 2.125 liters of juice

Answer:

  a[n] = n² +2n +9

Step-by-step explanation:

First differences are ...

  17-12 = 5; 24-17 = 7; 33-24 = 9 . . . . . . define d1=5

So, second differences are ...

  7-5 = 2; 9-7 = 2 . . . . . . . define d2=2

The coefficient of the n² term is half the second difference (=d2/2). The 0-th term will be smaller than the first term by the difference between the first first difference and the second difference (d1-d2):

  a0 = a1 -(d1 -d2) = 12 -5 +2 = 9

So, the quadratic rule will be ...

  a[n] = n² +9 +kn

for some value of k.

We can find k using the first term of the sequence.

  a[1] = 1² +9 +k·1 = 12

  k = 12 -10 = 2

Then the rule is ...

  a[n] = n² +2n +9

Answer:

Step-by-step explanation:

100% slope is -3 because you need to move down 3 times which is -3 and move to the right once which is 1

Slope= rise/run

Slope=-3/1 which equals -3

y-intercept= 2 because you just look at the y-axis and see any points that connects to it while the x is zero

If a football field is 100 yd long, how would you find its length in miles?

Answers

Answer:

If it is yards to miles, you divide. Precisely by 1760.

Therefore, if you were to divided 100 bye 1760, it would be around 0.0568182

Step-by-step explanation:

1 yard is 1/1760 fraction of a mile therefore football field will be 0.05682 miles long.

What is unit conversion?

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.

Another example could be kilo gram to gram.

1 mile = 1760 yards.

Divide by 1760

1760/1760 yards = 1/1760 mile

1 yard = 1/1760 mile

Multiply by 100

100 yard = 100/1760 mile

100 yard = 0.05682 mile

Hence "1 yard is 1/1760 fraction of a mile therefore football field will be 0.05682 miles long".

BE||CD. Find the value of x and AC.

Answers

Answer:

x = 4.8

AC = 16.8

Step-by-step explanation:

From the picture attached,

In ΔABE and ΔACD

BE║CD, and the AC and AD are the transversal lines.

∠ABE ≅ ∠ACD [Corresponding angles]

∠AEB ≅ ∠ADC [Corresponding angles]

ΔABE ~ ΔACD [By AA property of similarity of two triangles]

And by the property of similar triangles, corresponding sides of the similar triangles are always proportional.

[tex]\frac{\text{AC}}{\text{AB}}=\frac{\text{AD}}{\text{AE}}[/tex]

[tex]\frac{x+12}{12}=\frac{10+4}{10}[/tex]

[tex]\frac{x+12}{12}=\frac{14}{10}[/tex]

10(x + 12) = 12 × 14

10x + 120 = 168

10x = 168 - 120

x = 4.8

AC = x + 4.8

     = 12 + 4.8

     = 16.8
