The answer is 550.
Step by step explanation:
4/100•25=100/100
22•25=550
Answer:
2(n-9)
Step-by-step explanation:
Hi there!
Let "a number" = n.
"The difference" translates to subtraction, so when the question tells us "the difference of a number and 9", it translates to "n-9".
"Twice" means we'll be doubling something. In this case, we're doubling "n-9":
2(n-9)
I hope this helps!
Answer:
- sin(θ) = -(4√15)/17
- cos(θ) = 7/17 . . . . . . . given
- tan(θ) = -(4√15)/7
- csc(θ) = -(17√15)/60
- sec(θ) = 17/7
- cot(θ) = -(7√15)/60
Step-by-step explanation:
The relationship between sine and cosine is ...
sin² + cos² = 1
Solving for sine gives ...
sin = ±√(1 -cos²)
In this problem, we want the negative root.
sin(θ) = -√(1 -(7/17)²) = -√(240/289) = -(4√15)/17
tan(θ) = sin(θ)/cos(θ) = ((-4√15)/17)/(7/17) = -(4√15)/7
___
And the inverse functions are ...
sec(θ) = 1/cos(θ) = 17/7
csc(θ) = 1/sin(θ) = -17/(4√15) = -(17√15)/60
cot(θ) = 1/tan(θ) = -(7√15)/60
_____
Of course, you're aware that 1/√15 = (√15)/15.
Answer:
Step-by-step explanation:
Remark
You have to guess what the question is. I'm assuming that it is either the black triangle to the blue one or the blue one to the black one. Be careful when you post a question to see if you have included a question.
Answer
<em>Ratio of blue to black</em>
The distance of the left most point of the blue triangle to the y axis is 3. The same point on the black one is 1
blue/black = 3/1
<em>Ratio of black to blue</em>
ratio of the black triangle to the blue one is 1/3
The answer will depend on the question. Notice that the two answers are reciprocals.
Answer:
Option b is correct.
The series 20-15+10-5....is Divergent
Step-by-step explanation:
Alternating series Test:
satisfies:
- for all n
Then the series converges,
otherwise diverges.
Given the series: 20-15+10-5....
This is a alternating series:
using the alternating series test;
for all n
⇒ the series diverges.
therefore, the given series i,e 20-15+10-5.... is divergent.
