Answer:

the first set of values is correct

Step-by-step explanation:

when x =0,

y = 3(0) -1

y=-1

when x =1,

y=3(1)-1

y=2

when x=2,

y=3(2)-1

y=5

Answer:

The value of f(2) would be -40.

Step-by-step explanation:

Given function is,

$f(x) = 2x^3 - 3x^2 - 18x - 8$

Substituting x = 2 in the above function,

We get,

$f(2) = 2(2)^3 - 3(2)^2 - 18(2) - 8$

$=2(8) - 3(4) - 36 - 8$

$=16 - 12 - 44$

$\implies f(2)= -40$

Hence, the value of f(2) would be -40.

Question 1 of 10

Archy [21]

Answer:

A. y = 7(x + 1)²-3

Step-by-step explanation:

Parabola:

$y = 7x^{2} + 14x + 4$

$y = 7(x^{2} + 2x) + 4$

Putting into vertex form, remember that:

$(x + a)^{2} = x^{2} + 2ax + a^{2}$

In this question:

$x^{2} + 2x$ , to put into this format:

$x^{2} + 2x + 1 = (x + 1)^{2}$

We add one inside the parenthesis to do this. The parenthesis is multiplied by 7, so for the equivalent, we also have to subtract 7. Then

Vertex form:

$y = 7(x^{2} + 2x + 1) + 4 - 7$

$y = 7(x + 1)^{2} - 3$

So the correct answer is:

A. y = 7(x + 1)²-3

It would be awesome for some help! :3 Johnny Uses a wheelbarrow to move planting soil to a delivery truck. The volume of plantin

EleoNora [17]

We are given with
dimensions of wheelbarrow = 2ft x 3ft x 1.5 ft
dimensions of truck = 11 ft x 8 ft x 6 ft

The volume of the wheelbarrow is 2(3)(1.5) = 9 ft3
The volume of the truck is 11(8)(6) = 528 ft3
70% of this is
528 ft3 (0.7) = 369.6 ft3
Dividing this by the volume of the wheelbarrow
369.6 ft3 / 9 ft3 = 41.07
He would need to use the wheelbarrow 42 times.
