An Isosceles Right Triangle is a right triangle that consists of two equal length legs.

i.e opp = adj

hyp\(^2\) = adj\(^2\) + opp\(^2\)

2\(^2\) = x\(^2\) + x\(^2\)

4 = 2x\(^2\)

2 = x\(^2\)

√2 = x

Correct Answer: C. \(\frac{x_3}{3}\) + \(\frac{3x_2}{2}\) - 5x + k

Explanation

(a) A leper knelt before Jesus and besought him to heal him. Jesus stretched out his hand and touched him saying, "be clean". Immediately, the leper was healed; he became clean. Then Jesus warned him not to tell anybody or spread the news, but to go to the priest and offer, for his cleansing, what Moses commanded as a proof to the people. But he went out and began to spread the news such that the crowd that gathered around Jesus made it difficult for him to enter openly into the town. Jesus remained in the countryside where people came to him from all over the place.

The significance of the instructions given to the cleansed leper by Jesus were:

(i) Jesus wanted to keep his messiahship secret because it was yet too early to expose himself as, he needed some time for his teaching to permeate people's hearts to enable them fully appreciate the true meaning of his messiahship through his death on the cross and salvation for man.

(ii) Again, his teaching ministry was of greater importance than his healing ministry. Hence, if those healed were to spread the news about their healing, the crowd that would come for similar healings would disturb his teaching ministry.

(iii) Jesus obeyed the Mosaic law, especially as it was in accordance with God's law of mercy and kindness. It was also the role of priests to declare a leper clean, to make him acceptable in society. Jesus' concern for the sick made him advise the healed leper to do everything to remove the stigma of ostracism he had suffered froth for so long.

(b) Some ways by which God performs miracles today include:

(i) God continues to perform miracles of healing through doctors, nurses, surgeons, etc:

(ii) Many Christians have been healed because of their faith. This is the belief of many churches today.

(iii) In miraculous ways, sinners have been converted to saints or believers with the local churches as agents of Christ.

Correct Answer: B. 2.0V

Correct Answer: D. English

Correct Answer: A. -5.5

Explanation

\(\int_{\frac{1}{2}}^{1} \frac{x^{3} - 4}{x^{3}} \mathrm {d} x \equiv \int_{\frac{1}{2}}^{1} 1 - \frac{4}{x^{3}} \mathrm {d} x\).

= \(\int_{\frac{1}{2}}^{1} 1 - 4x^{-3} \mathrm {d} x\).

= \(\left. x - \frac{4x^{-2}}{-2}\right |_{\frac{1}{2}}^{1} = \left. x + \frac{2}{x^{2}}\right |_{\frac{1}{2}}^{1}\)

= \((1 + 2) - (\frac{1}{2} + 8) = 3 - 8.5 = -5.5\)
