Well start at 0,1,2,3, etc. and plug in the numbers until you get you answer of 2!

I THINK the value of x = 1

Divide both sides by 2:

2x^3/2 = 2/2

x^3 = 1

Take the cube root:

x = 1^1/3

x = 1

If someone can confirm this, that would be greatly appreciated. Thank you :)

Describe and correct the error in finding csc θ, given that θ is an acute angle of a right triangle and cos θ =7/11

a_sh-v [17]

Answer:

<h2>cosecθ = 1/sinθ = 11/6√2</h2>

Step-by-step explanation:

Given that cos θ =7/11, cosec θ = 1/sinθ in trigonometry.

Based on SOH, CAH, TOA;

cosθ = adjacent/hypotenuse = 7/11

adjacent = 7 and hyp = 11

Since sinθ = opp/hyp, we need to get the opposite to be able to calculate sinθ.

Using pythagoras theorem to get the opposite;

$hyp^{2} = adj^{2} + opp ^{2} \\opp = \sqrt{hyp^{2} - adj^{2} } \\opp = \sqrt{11^{2} - 7^{2}} \\opp = \sqrt{72} \\opp = 6\sqrt{2}$

sinθ = 6√2/11

cosecθ = 1/sinθ = 1/( 6√2/11)

cosecθ = 1/sinθ = 11/6√2

Note the error; cscθ $\neq$ 1/cosθ but cscθ = 1/sinθ

Mia cut a piece of felt into 3 equal

morpeh [17]

Answer:

$\frac{1}{3}$

Step-by-step explanation:

Mia used One Third of the felt for her art project. 3/3 would be the whole felt together. Since one part of three sections was used up then this means that 1/3 was used.

Answer:

x ≥ -4

Step-by-step explanation:

-3x + 2 ≤ 14

Subtract 2 from each side

-3x+2-2 ≤ 14-2

-3x ≤ 12

Divide each side by -3 . Remember that dividing by a negative flips the inequality.

-3x/-3 ≥12/-3

x ≥ -4
