Answer:

Step-by-step explanation:

Notez que: un quintal =

une unité de poids égale à 100 kg

Un jardinier a récolté deux quintaux et trois quarts de pommes.

Le nombre total de pommes récoltées = 200 kg + 3/4 du quintal de pommes

= 200 kg + 0,381 kg

= 200,381 kg

Il vend un quintal un quart à un voisin

Le montant qu'il a vendu à un voisin = 100 + 1/4 quintal de pommes

100 + 0,127

= 100,127 kg

Il vend également 7/10 d'un quintal sur le marché du village

= 7/10 × 100 kg

= 70 kg de pommes restantes

2/5 d'un quintal à un pâtissier.

2/5 × 100 kg

= 40 kg de pommes restantes

À l'aide d'une fraction, exprimez la quantité de pomme que le jardinier a gardée pour lui.

La quantité que le jardinier lui a réservée =

200 3/4 kg - (100 1/4 kg + 70 kg + 40 kg)

200,381 kg - (210,127 kg)

For what values of m does the graph of y = 3x2 + 7x + m have two x-intercepts
Irina18 [472]

we are given

y=3x^2+7x+m

To find x-intercept means we have to find zeros

and for finding zeros , we will use quadratic formula

and we have it has two x-intercepts

so, it's discriminant must be greater than 0

so, we will find discriminant

D=\sqrt{b^2-4ac}

now, we can compare with

y=ax^2+bx+c

y=3x^2+7x+m

and then we can find a , b and c

a=3,b=7,c=m

now, we can find D

D=\sqrt{7^2-4*3*m}

D=\sqrt{49-12m}

It has two x-intercepts

so,

D=\sqrt{49-12m}>0

now, we can solve for m

49-12m>0

12m

Simplify.
Kazeer [188]
(1/2)^2 = 1/4
2-2/3 = 6/3 - 2/3 = 4/3

OK so:
(1/2)^2 - 6(2-2/3) = 1/4 - 6(4/3)
= 1/4 - 8
= 1/4 - 32/4
= -31/4

Answer:

2.50

Step-by-step explanation:

Given

(x_1,y_1) = (-1,0.8)

(x_2,y_2) = (0,2)

(x_3,y_3) = (1,5)

(x_4,y_4) = (2,12.5)

Required

The rate of change (b)

The above graph is represented as:

y = ab^x

For: (x_2,y_2) = (0,2);

We have:

y = ab^x

2 = a * b^0

2 = a *1

2 = a

a = 2

For (x_3,y_3) = (1,5),

We have:

y = ab^x

5 = a * b^1

5 = a * b

Substitute a = 2

5 = 2 * b

Divide by 2

2.5 = b

b = 2.5

<em>Hence, the rate of change is 2.50</em>
