1. find the exact value of cos2θ if sin 2θ=3/4 and θ is between 0° and 90°

musickatia [10]

Answer:

<u>Identities used:</u>

sin²θ + cos²θ = 1
cos2θ = cos²θ - sin²θ

sin2θ = 3/4, and θ in the first quadrant
cos²2θ = 1 - sin²2θ
cos2θ = √(1 - sin²2θ) = √(1 - 9/16) = √(7/16) = √7 / 4

sinθ(cos²θ - cos2θ) =
sinθ(cos²θ - (cos²θ - sin²θ) =
sinθ(sin²θ) =
sin³θ

Which radical expressions are equivalent to the exponential expression below ? Check all that apply . (13 + 8) ^ (1/2) A. (13 +

Fantom [35]

Answer:

$(B)\sqrt{21}\\(C)\sqrt{13+8}$

Step-by-step explanation:

Given the expression $(13 + 8) ^{1/2}$

Using law of indices: $a^{1/2}=\sqrt{a}$

$(13 + 8) ^{1/2}=\sqrt{13+8}$

Also:13+8=21

Therefore:

$(13 + 8) ^{1/2}=21^{1/2}\\=\sqrt{21}$

A car is driving at the speed of 58 kilometers per hour. how much time will it take to drive for distance of 32 miles ?

quester [9]

well, we know that there are 1.609 kilometers in 1 mile, so 58 kilometers will be 58 ÷ 1.609 ≈ 36.05 miles.

we know the car is doing 36.05 miles in 1 hour, how long will it be for 32 miles?

$\bf \begin{array}{ccll} miles&hours\\ \cline{1-2} 36.05&1\\ 32&x \end{array}\implies \cfrac{36.05}{32}=\cfrac{1}{x}\implies 36.05x=32 \\\\\\ x=\cfrac{32}{36.05}\implies x\approx 0.8877\qquad \leftarrow \textit{53 minutes and about 16 seconds}$
