Which quadratic function in standard form has the values a = –3.5, b = 2.7, and c = –8.2?
sweet-ann [11.9K]

Answer:

f(x)=-3.5x²+2.7x - 8.2

Step-by-step explanation:

We have given:

a = -3.5 , b=2.7 and c= -8.2

We have to write  quadratic function in standard form.

We know that the standard form of quadratic function is:

f(x)=ax²+bx+c

where a, b, and c being constants, or numerical coefficients, and x is an unknown variable.

We have the values a= -3.5 , b = 2.7 and c = -8.2

Substitute the values  in the standard form:

f(x)=-3.5x²+2.7x - 8.2

Therefore the answer is: f(x)=-3.5x²+2.7x - 8.2 ....

a cargo ship arrived at Kingston Harbour carrying 403,172 kilograms of flour. All the flour was tranfered to 5 trains and 9 truc
IrinaVladis [17]

Each train carried 64141 kg of flour and each truck carried 9163 kg of flour.

Step-by-step explanation:

Let the no. of kg of flour carried by each train be 'a'

Let the no. of kg of flour carried by each truck be 'b'

Total flour = 403172 kg

No. Of trains = 5

No. of trucks = 9

a = 7(b)

5a + 9b = 403172

5(7b) + 9b = 403172

35b + 9b = 403172

44b = 403172

b = 403172/44

b = 9163

Each truck carried 9163 kg of flour.

a = 7b

a = 7(9163)

a = 64141

Each train carried 64141 kg of flour.
