Higher June 2022 Paper 3 Q2
2 \(T = 4m^2 - 11\)
(a) Work out the value of \(T\) when \(m = -3\) (2)
(b) Make \(p\) the subject of the formula \(d = 3p + 4\) (2)
| Answer | Mark | Mark scheme |
|---|---|---|
| 25 | M1 | for (\(T =\)) \(4 \times (-3)^2 - 11\) or \(4 \times (-3)^2 = 36\) |
| A1 | cao |
Additional guidance
Can accept missing brackets.
| Answer | Mark | Mark scheme |
|---|---|---|
| \(p = \dfrac{d - 4}{3}\) oe | M1 | for a correct first step, eg \(d - 4 = 3p\) or \(\dfrac{d}{3} = p + \dfrac{4}{3}\) or for \(\dfrac{d - 4}{3}\) as answer |
| A1 | for \(p = \dfrac{d - 4}{3}\) oe |
Additional guidance
May be in unsimplified form,
eg \(d - 4 = 3p + 4 - 4\)
