Answer:

a = 1
b = -3
c = -2

Step-by-step explanation:

The general form of a quadratic equation is often written as ...

ax² +bx +c = 0

The references to "a", "b", and "c" are to the coefficients in this form. Comparing this to your equation ...

x²-3x -2 = 0

we see that the coefficient of x², is 1, so a=1; the coefficient of x is -3, so b=-3, and the constant is -2, so c=-2.

A school pays $1,825 for 150 shirts. This includes the $25 flat-rate shipping cost.

yKpoI14uk [10]

Answer:

We know that the total cost for the 150 shirts (plus a flat-rate of $25) is $1,825.

First, let's find how much costs each shirt.

First, the total cost of the shirts alone (neglecting the flat-rate) is:

$1,825 - $25 = $1,800

Then each shirt costs equal to the quotient of the cost and the number of shirts:

$1,800/150 = $12

Each shirt costs $12.

Then if you order T shirts, the total cost will be the flat-rate of $25 plus T times $12. The equation is:

C(T) = $25 + T*$12

b) C represents the cost

T represents the number of shirts ordered.

c) The initial value is the constant value, in this case, is $25

The rate of change is the coefficient that multiplies the independent variable (T), in the equation the rate of change is $12.

vladimir2022 [97]

Answer:

They make 27 two points basket.

Step-by-step explanation:

Given:

Kelly's basketball team made a total of 33 two points and three point baskets in their game last week.

If her team scored a total of 72 points.

Now, to find the number of two points baskets they make.

Let the two points basket be $x.$

And the three points basket be $y.$

So, total number of two points and three point baskets are:

$x+y=33$

$y=33-x\ \ \ .........(1)$

Now, the total points team scored:

$2x+3y=72$

Substituting the value of $y$ from equation (1) we get:

$2x+3(33-x)=72$

$2x+99-3x=72$

Subtracting both sides by 99 we get:

$2x-3x=-27$

$-x=-27$

Dividing both sides by -1 we get:

$x=27.$

The the two points basket = 27.

Therefore, they make 27 two points basket.

A fly trapped inside a cubical box with side length 1 meter decides to relieve its boredom by visiting each corner of the box. I

Lelu [443]

Answer:

(4 √ 3 + 4 √2 ) m

Step-by-step explanation:

The insect can travel from one corner directly to opposite corner in four different ways

each can be calculated using Pythagoras theorem

firstly for one face we need to calculate the diagonal

H² = 1² + 1² = 2

H = √2

then we calculate the diagonal opposite a corner

for example

A to H where A is at the bottom and H opposite A in another plane at the top in the cubical box

(Interior diagonal for A to H)² = √2² + 1² = 3

Interior diagonal from A to H = √ 3

there are four such corners, the fly will travel 4 √ 3 and it could also go 4 √2 diagonally to the the other corners

maximum possible length in meters = (4 √ 3 + 4 √2 ) m
