Answer:
-0.7
Step-by-step explanation:
-2n+1.8=3.2
-2n=3.2-1.8
-2n=1.4
n=1.4/-2
n=-0.7
Answer:
a. 40°
b. 21°
Step-by-step explanation:
a. Reference angle = θ
Opposite = 5
Adjacent = 6
Apply TOA:
(nearest degree)
b. Reference angle = x
Opposite = 5
Hypotenuse = 14
Apply SOH:
(nearest degree)
Answer:
C
Step-by-step explanation:
sine uses opposite over hypotenuse
the opposite of x is 20 and the hypotenuse is 29
so the answer is 20/29
The potential solutions of are 2 and -8.
<h3>Properties of Logarithms</h3>
From the properties of logarithms, you can rewrite logarithmic expressions.
The main properties are:
- Product Rule for Logarithms -
- Quotient Rule for Logarithms -
- Power Rule for Logarithms -
The exercise asks the potential solutions for . In this expression you can apply the Product Rule for Logarithms.
Now you should solve the quadratic equation.
Δ=. Thus, x will be . Then:
The potential solutions are 2 and -8.
