Answer:

11x + 6x^2 -57

Step-by-step explanation:

(7x2 + 5)(x - 3) + 2x (3x - 4)

1. Multiply 7x2

(14 + 5)(x - 3) + 2x (3x - 4)

2. Add 14+5

(19)(x - 3) + 2x (3x - 4)

3. Distribute 2x to 3x-4

(19)(x - 3) + 6x^2 - 8x

4. Distribute 19 to x-3

19x - 57 + 6x^2 - 8x

5. Simplify.

11x + 6x^2 -57

Help please! (no one was answering it in physics and i really need help)

Let v_0 be the cat's speed just as it leaves the edge of the table. Then taking the point 1.3 m below the edge of the table to be the origin, the cat's horizontal position at time t is given by

x(t)=v_0t

and its height is

y(t)=1.3\,\mathrm m-gt^2

where g is 9.8 m/s^2, the magnitude of the acceleration due to gravity.

The time it takes for the cat to hit the ground is t with

0=1.3\,\mathrm m-gt^2\implies t=\sqrt{\dfrac{1.3\,\rm m}g}\approx0.36\,\mathrm s

(Unfortunately, this doesn't match any of the given options...)

The cat lands 0.75 m away (horizontally) from the edge of the table, so that its speed v_0 was

0.75\,\mathrm m=v_0(0.36\,\mathrm s)\implies v_0\approx2.08\dfrac{\rm m}{\rm s}

(Again, not one of the answer choices...)

I'm guessing there's either a typo in the question or answers.

What is the Line that passes through (2,0) and (0,1)
zimovet [89]

To find the slope you use the equation:

m = (y₂-y₁) ÷ (x₂-x₁)

You plug in the two points into this equation to find m (m is the slope)

m = (1 - 0) ÷ (0 - 2)

m = 1 ÷ (-2)

m = - 1/2

Next you use this equation:

y = mx + b

Because you know m you plug it in.

y = -1/2x + b

Now you need to find b. To do so you plug in either of the points into this equation(you come out with the same answer for b)

y = -1/2x + b

1 = -1/2(0) + b

1 = b

Finally you plug in b and you get your new equation.

y = -1/2x + 1
