Correct the following statement and rewrite: Roots conduct water to the leaves.
Answer
Stem conducts water to the leaves not the roots. Roots absorb water from the soil through root hair and transport the water in upward direction in plants.
If \( 8tanA=15, \)then the value of \( \frac{sin\theta -cosA}{sin\theta +cosA}\) is (A) \( \frac{7}{23}\) (B) \( \frac{11}{23}\) (C) \( \frac{13}{23}\) (D) \( \frac{17}{23}\)
If \( \sqrt{3}tan\theta =3sin\theta ,\) then the value of \( si{n}^{2}\theta -co{s}^{2}\theta \) is (A) \( \frac{1}{2}\) (B) \( \frac{1}{3}\) (C) \( \frac{1}{4}\) (D) \( \frac{1}{5}\)
If a and b are real number such that \( acos\theta +bsin\theta =4\) and \( asin\theta -bcos\theta =3\), then \( {(a}^{2}+{b}^{2})\) is (A) 7 (B) 12 (C) 25 (D) \( \sqrt{12}\)
If A is an acute angle and \( tanA=\frac{5}{12}, \)the value of case A is (A) \( \frac{11}{5}\) (B) \( \frac{13}{5}\) (C) \( \frac{16}{5}\) (D) \( \frac{17}{5}\)
If \( \alpha \) and \( \beta \) are the roots of the quadratic equation \( 4{x}^{2}+2x-1=0\) then the value of \( \sum _{r=1}^{\infty }\left({\alpha }^{r}+{\beta }^{r}\right)\) is: (a) \( 2\) (b) \( 3\) (c) \( 6\) (d) \( 0\)
