Steps to solve:
(4.7 x 10^4)(6.4 x 10^15)
~Combine like terms
(4.7 x 6.4)(10^4 x 10^15)
~Simplify
30.08 x 10^4+15
30.08 x 10^19
~Divide by 10 to get a number less then 10
30.08/10 x 10^19
3.008 x 10^20
Therefore, the answer is A) 3.008 x 10^20
Best of Luck!
Answer:
|x| - 17 = 0
Step-by-step explanation:
<u>The measure of the arc CD = 64°</u>
It is required to find the measure of the arc CD in degrees.
So, as shown at the graph
BE and AD are are diameters of circle P
And ∠APE is a right angle ⇒ ∠APE = 90°
So, BE⊥AD
And so, ∠BPE = 90° ⇒(1)
But it is given: ∠BPE = (33k-9)° ⇒(2)
From (1) and (2)
∴ 33k - 9 = 90
∴ 33k = 90 + 9 = 99
∴ k = 99/33 = 3
The measure of the arc CD = ∠CPD = 20k + 4
By substitution with k
<u>∴ The measure of the arc CD = 20*3 + 4 = 60 + 4 = 64°</u>
