what is the formula for quadratic equations?

Answer:

Step-by-step explanation:

Given is a table of x, f(x) as below

x             1   3   4   6   7  9  10

f(x)         4   8  6  10  10  12  16

Mid pt      6   7   8  10   11  14

width of

interval    2   1     2   1    2    1

dA1         12   7   16  10  22  14

area = area of all rectangles= 81 sq units.

Answer:

[tex]10:02:24\ \text{pm}[/tex]

Step-by-step explanation:

d = Distance to travel = 880 miles

s = Average speed of the car = 65 mph

Time taken to cover the distance is

[tex]t=\dfrac{d}{s}\\\Rightarrow t=\dfrac{880}{65}\\\Rightarrow t=\dfrac{176}{13}\ \text{h}=13.54\ \text{hours}[/tex]

Time the car stopped

[tex]3\times 10+60=90\ \text{minutes}=1.5\ \text{hours}[/tex]

Total time of the journey

[tex]13.54+1.5=15.04\ \text{hours}[/tex]

Converting [tex]0.04\ \text{hours}[/tex] to minutes

[tex]0.04\times 60=2.4[/tex]

So, the total time taken for the journey is [tex]15\ \text{hours and }2\ \text{minutes and }24\text{seconds}[/tex]

Time when they reach their destination

[tex]7:30+15:2.4\approx 10:02:24\ \text{pm}[/tex]

Answer:

a = 55

Step-by-step explanation:

By exterior angle theorem:

a+10 + 44 = 2a

a= 55

Here's the proof:

Consider the same figure shown

say a+10 = x and 44 = y

Thus the remainng angle is 180 - x-y

and the exterior angle is 180- ( 180 - x- y) = x+y

Thus proved

Answer:

Place a filled in dot at -3 with a ray heading to the right

Step-by-step explanation:

Answer:

The distributive property tells us that: a(b-c) = ab-ac.

So in this problem we have: -2(3x-7) = -2(3x) - (-2)(7) = -6x+14

Answer:

5 watts

Step-by-step explanation:

power (measured in watts) is joules per second, or J/s

J = 20

s = 4

J/s = 5

Answer:

There are 14 pencils and 8 are blue

The probability of picking blue in the first pick = 8/14 =4/7.

The probability of picking blue in the second pick = 7/13 (as no replacement was there).

There are 14pencils and 6 are red.

The probability of picking red in the first pick = 6/14 =3/7

The probability of picking red in the second pick = 5/13. (as no replacement was there).

Answer:

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square, you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Answer:

Base x Width x Height

Answer:

-4 ≤ x ≤ 6

Step-by-step explanation:

When we talk of the domain, we are referring to the possible x-values

from the diagram, we can see that we have the x-values at -4 and 6

The dotted line means that -4 and 6 are in the domain

Thus, the two points represent the end and starting point of the domain

Writing this in interval notation, we have the representation as;

-4 ≤ x ≤ 6

Answer: In 1 hour , it will waste = 1.25ml

Step-by-step explanation:

Volume of water  wasted by the tap in 9 Hours = 11,250 ml

Since  it drips in equal quantity,

In 1 hr , it will drip=  1 x 11,250 / 9 = 1,250 ml

But  1000 ml = 1 Liter

1250 ml = 1250ml x 1Liter / 1000ml= 1.25L

Answer:

6x - 18

Step-by-step explanation:

3 x 6 = 18, so thats how you get the 18 in the answer

3 x 2x = 6x, which is how you get the 6x

and theres  a subraction sign so we know to put a - there.

Answer:

6x - 18

Step-by-step explanation:

3(2x - 6) =

("... - 6" means that whatever we do with the 6, we have to remember that it's negative)

3(2x - 6) =

3 * 2x + 3 * (-6) =

6x + (-18) =

(if we add a negative number then it's the same as subtracting that number)

6x + (-18) = 6x - 18
