.Given: F(x) = 3x2+ 1, G(x) = 2x - 3, H(x) = x
inna [77]

For this case we have the following functions:

F (x) = 3x ^ 2 +1\\G (x) = 2x-3\\H (x) = x

We have to:

G (x) * - 1 is given by:

(2x-3) * - 1 = -2x +3

Thus, the correct option is the option is A.

On the other hand,

F (x) +G (x) = 3x ^ 2 +1 +(2x - 3) = 3x ^ 2+ 1+ 2x-3 = 3x ^ 2 +2x-2

Thus, the correct option is the option is A.

We also have:

F (-2) = 3 (-2) ^ 2+ 1 = 3 (4)+ 1 = 12+ 1 = 13

Thus, the correct option is the option is B.

Last we have:

F (3)+G (4) -2H (5) = (3 (3) ^ 2+ 1)+ (2 (4) -3) -2 (5) = (3 (9)+ 1) - (8-3) 10 = 28+ 5-10 = 33

Thus, the correct option is the option is C.

ANswer:

Option A, A, B, C

Maths * Henry is mixing concrete. To make concrete he needs to mix cement, sand and gravel in the ratio 4 : 3 : 1 by weight. Hen
Mice21 [21]

Answer:

His 55 kg of cement is 5 kg short of the 60 kg he needs.

Step-by-step explanation:

Let r be a ratio useful in determining how much of each ingredient Henry needs:

4/8 of the mix is cement, 3/8 is sand and 1/8 is gravel.

4/8 of the total 120 kg must then be 60 kg made up of cement;

3/8                                 must then be 45 kg made up of sand; and

1/8                                   must then be 15 kg made up of gravel

His 55 kg of cement is 5 kg short of the 60 kg he needs.
