Answer:
Step-by-step explanation:
x³ = 4³ = 4 * 4 * 4 = 64
Answer:

Step-by-step explanation:
Given that,
R₁ = 100 ohms
R₂ = 200 ohms
We need to find the equivalent resistance of the circuit. So,

So, the equivalent resistance is
.
Answer:
A) 20°
Step-by-step explanation:
Sine and cosine are co-function complements which means that value of sine of an angle is equal to the value of cosine of the complementary angles.
This can be represented by:


Given statement:

Applying co-function complements

Since, we can represent 70° = 90°-20°
So
Thus,
makes the statement true.
Answer:
Step-by-step explanation:
a₁ = πr₁⁵ = 25π cm²
a₂ = 25(25π) = 625π cm²
r₂ = 25 cm
