The correct answer is A. $d* log_ba$

Step-by-step explanation:

According to the power rule for logarithms, the logarithm of a power can be simplified by writing it as the product of the exponent multiplied by the logarithm of the base.

For example;

$log_b(M^n)=nlog_bM$

Hence in this case,

$log_ba^d=d*log_ba$

In the following figure, the value of x is____

zubka84 [21]

Answer:

x ≈ 8.3 ( to the nearest tenth )

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos41° = $\frac{adjacent}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{x}{11}$

Multiply both sides by 11

11 × cos41° = x, thus

x ≈ 8.3
