Answer:

x = (-5/2)

Step-by-step explanation:

4 - (2x + 4) = 5

-4 from both sides

- (2x + 4) = 1

divide both sides by -1

2x + 4 = -1

-4 from both sides

2x = -5

divide both sides by 2

x = (-5/2)

Answer:

D. x = -5⁄2

Step-by-step explanation:

4 - (2x + 4) = 5

4 - 2x - 4 = 5

-2x = 5

-2½ = x

* -2½ = -5⁄2

a){10}^{0}  \\ b)  {10}^{ - 7}  \\  c){10}^{7}  \\  d) {10}^{1}

Step-by-step explanation:

{1000}^{ - 3}  =   {10}^{3 + ( - 3)}  =  {10}^{0}  \\  {0.0001}^{ - 4}  =  {10}^{ - 3 +  - 4}  =  {10}^{ - 7}  \\  {100}^{5}  =  {10}^{2 + 5}  =  {10}^{7}  \\  {0.001}^{3}  =  {10}^{ - 2 + 3}  =  {10}^{1}

An acute angle, θ, is in a right triangle such that sin of theta is equal to 3 over 8 period What is the value of cot θ?
Serggg [28]

We want to find the value of cot(θ) given that sin(θ) = 3/8 and θ is an angle in a right triangle, we will get:

cot(θ) = (√55)/3

So we know that θ is an acute angle in a right triangle, and we get:

sin(θ) = 3/8

Remember that:

  • sin(θ) = (opposite cathetus)/(hypotenuse)
  • hypotenuse = √(  (opposite cathetus)^2 +  (adjacent cathetus)^2)

Then we have:

opposite cathetus = 3

hypotenuse = 8 = √(3^2 +  (adjacent cathetus)^2)

Now we can solve this for the adjacent cathetus, so we get:

adjacent cathetus = √(8^2 - 3^2) = √55

And we know that:

cot(θ) = (adjacent cathetus)/(opposite cathetus)

Then we get:

cot(θ) = (√55)/3
