Rationalise the denominator of 1/(2√5 + √3)

wlad13 [49]

Answer:

$\bf ➤ \underline{Solution-} \\$

$\sf \: \: \: \dfrac{1}{ 2 \sqrt{5} + \sqrt{3} }$

On rationalising,

$\sf \implies\dfrac{1}{ 2 \sqrt{5} + \sqrt{3} } \times \dfrac{2 \sqrt{5} - \sqrt{3}}{2 \sqrt{5} - \sqrt{3}}$

Combine the fractions,

$\sf \implies \dfrac{1(2 \sqrt{5} - \sqrt{3})}{(2 \sqrt{5} + \sqrt{3})(2 \sqrt{5} - \sqrt{3})}$

We know that,

$\sf \implies (a + b)(a - b) = (a)^{2} - (b)^{2}$

So,

$\sf \implies \dfrac{1(2 \sqrt{5} - \sqrt{3})}{(2 \sqrt{5} )^{2} - (\sqrt{3})^{2} }$

$\sf \implies \dfrac{1(2 \sqrt{5} - \sqrt{3})}{20 - 3 }$

$\sf \implies \dfrac{1(2 \sqrt{5} - \sqrt{3})}{17 }$

$\sf \implies \dfrac{2 \sqrt{5} - \sqrt{3}}{17 }$

Hence,

On rationalising we got,

$\bf \implies\dfrac{2 \sqrt{5} - \sqrt{3}}{17 }$

If sin is 3/4 and tan is -3/4, then cos is ?

nadya68 [22]

Answer:

$cos=1$

Step-by-step explanation:

Use the acronym SOH-CAH-TOA

sin = $\frac{3}{4}$

So opposite is 3 and hypotenuse is 4.

tan = $\frac{-3}{4}$

So opposite is -3 and adjacent is 4.

cos = adjacent/hypotenuse

cos = $\frac{4}{4}=1$

Luke bought three canvas boxes to store his papers. The canvas boxes have dimensions of 12 inches by 10 inches by 12 inches. Wha

irga5000 [103]

Answer: 4,320 inches cubed.

Step-by-step explanation:

step 1----- Volume of 1 canvas box

Volume of solid for a rectangular box = Length x width xHeight

where Length= 12inches,

Width= 10 inches

Height= 12 inches

Volume of a Canvas box= 12 X 10 X 12= 1440 inches cubed

Step 2== Volume of 3 canvas boxes

1 canvas box = 1440 inches cubed

therefore 3 canvas boxes =

1440 x 3= 4320 inches cubed.
