Answer:

Lol I hope she didn't hit you yet. The answer is x=14 :)

Step-by-step explanation:

So the first thing that you would want to do is find what 9 is multiplied by to get 21. To do this, we can just do a simple algebraic equation: 9x=21. The answer is 7/3 because mAgIc. So now, we can also multiply 6 by 7/3. this would be 42/3 because of more MaGiC. 42/3 divides into 14 because im  just obviously a mage. lol I hope this helped.

Answer:

150 ft^3

.1 ton or 200 lbs

Step-by-step explanation:

The volume is given by

V = l*w*h

V  = 5*5*6

V = 150 ft^3

To find how much 1 ft^3 weighed take the weight and divide by the volume

15 tons / 150 ft^3

.1 ton / 1 ft^3

1 ft^3  weights .1 ton

We know that 1 ton = 2000 pounds

.1 ton = 200 pounds

Could someone please answer question b) ii) ?<br> The question is on the attached image.
mel-nik [20]

Answer:

b) i) Curve A

ii) - 1.75

iii) x = 1 - √5  or x = 1 + √5

Step-by-step explanation:

b) i) We are given a function y = x² - 2x - 3 and the graph of this function is also shown in the side diagram.

The equation can be rearranged to y = (x - 1)² - 4

⇒ (x - 1)² = y + 4

Therefore, this is an equation of a parabola having the vertex at (1,-4) point and its axis is parallel to the positive y-axis.

So, the curve A represents the equation given. (Answer)

ii) Now, at x = 2.5, f(x) = 2.5² - 2 × 2.5 - 3 = - 1.75 (Answer)

iii) When y = 1, then x² -2x - 3 = 1

⇒ x² - 2x - 4 = 0

⇒ (x - 1)² - 5 = 0

⇒ (x - 1)² - (√5)² = 0

⇒ (x - 1 + √5)(x - 1 - √5) = 0

⇒ x = 1 - √5  or x = 1 + √5 (Answer)
