Answer:
f(1) = 81
Step-by-step explanation:
f(n + 1) = 1/3 f(n)
⇔ f(n) = 3 × f(n + 1)
……………………………
if f(3) = 9 ⇒ f(2) = 3 × f(3) = 3 × 9 = 27
Then
f(1) = 3 × f(2) = 3 × 27 = 81
Given:
In ΔNOP, n = 910 inches, o = 110 inches and p=820 inches.
To find:
The measure of ∠P to the nearest degree.
Solution:
According to the law of cosine:
Using law of cosine in triangle NOP, we get
Putting the given values, we get
Taking cos inverse on both sides, we get
Therefore, the measure of ∠P is 33°.
I think it is D or it could be c?
Answer:
$43 and
$17
Step-by-step explanation:
Let the amount James have be A and that of jada be B
Given
James and jada have $60 together
That’s
A + B = 60
And james A has $9 more than twice jada’s amount
That’s
A = 9 + 2B
We now have two equations
1. A + B = 60 and
2. A = 9 + 2B
Now put 9 + 2B as A in equation one
A + B = 60
9 +2B + B = 60
9 + 3B = 60
Subtract 9 from both sides
9 - 9 + 3B = 60 - 9
3B = 51
Divide both sides by 3
3B/3 = 51/3
B = 17
Jada has $17
Recall
A = 9 + 2B
And B = 17
Therefore
A = 9 + 2 x 17
A = 9 + 34
A = 43
James has $43
Therefore, James has $43 while jada has $17
Because they have lettters the (p's) go together which is -6p and then you have the +15 left so you add that on the end , your answer is -6p + 15
