From 2017 JAMB Mathematics past questions

Question: Integrate x2+3x-5

Solution:

Recall that the general power formula for integration is as shown in the image below:

Power Integral formula

Hence, ∫(x2 + 3x – 5) = x3/3 + 3x2/2 – 5x + k

From JAMB Mathematics past question 2017:

Question: Evaluate 0.0028213/0.634

Solution:

0.0028213/0.634

89/200

= 4.45 x 10-3

Question: Calculate the simple interest on ₦6,500 for 4 years at 6%.

Solution:

Recall that the formula for simple interest is A = PRT,

where:

A = simple interest,

P = principal amount,

R =rate per period and

T = time periods.

Hence,

A = 6500 * (6/100) * 4  = 1560

A = 1560
