A, C, B, respectively
Step-by-step explanation:
science(density and buoyancy)
For this case we must solve the following questions:
Question 1:
We should simplify the following expression:
Applying double C we have:
By definition of multiplication of powers of the same base we have to place the same base and add the exponents:
Canceling common terms:
Answer:
Option A
Question 2:
We should simplify the following expression:
So, we have:
Simplifying common terms:
Answer:
Option D
Question 3:
We factor the following expressions to rewrite the experience:
<em>: </em>We look for two numbers that multiplied give 10 and added 7:
<em></em> We look for two numbers that multiplied give -50 and added -5:
<em></em>
Rewriting the given expression we have:
We simplify common terms in the numerator and denominator we have:
Answer:
Option D
Answer:
θ ≈ 36.03°
Step-by-step explanation:
We can use tangent (opposite side / adjacent side) for this question:
tan (θ) = 8 / 11
θ = tan⁻¹ (8/11)
θ = 36.02737339
θ ≈ 36.03°
Answer:
-4
Step-by-step explanation:
f(x) = 4x - 12
Let x=2
f(2) = 4*2 - 12
= 8-12
= -4
