Answer:
<u>3.7</u>
Step-by-step explanation:
<u>Given</u>
- sin²θ + cos²θ = 1
- sinθ = 0.27
<u>Solving for cos</u>θ
- cos²θ = 1 - sin²θ
- cos²θ = 1 - (0.27)²
- cos²θ = 0.0729
<u>Finding tan</u>θ
- tanθ = sinθ / cosθ
- tanθ = 0.27 / 0.0729
- tanθ = <u>3.7</u>
<u>Verifying it lies in the range</u>
- θ = tan⁻¹ (3.7)
- θ = 74.88°
- Range is : 0 < θ < π/2 [or 0 < θ < 90°]
- It lies in the range [Verified]
Alright, so plugging it in, we get 2(-4)^2=2(2)^4+3^2-(-4)^2+2^4. Use PEMDAS with parenthesis and exponents to then get (2)(16)+9-16+16. Multiplying 1 and 16, we get 32+41-16+16=73
Step 1: Prioblem
Estimate the difference of 765 and 333. Explain your estimate.
Step 2: Concept and Method
Difference mean to subtract the smaller number from larger number.
Therefore,
Step 3: Final answer
= 432
Answer:
x = -1/8
Step-by-step explanation:
to determine the value of x in the expression-6=3/4x
first, cross multiply inorder to have a straight line equation ,then combine the like terms together and evaluate.
solution
-6=3/4x
using cross multiplication techique
4x × -6 = 3
-24x = 3
divide both sides by the coefficient of x which is -24
-24x/-24 = 3 /-24
x = -1/8
