Answer:
9.5%
Step-by-step explanation:
Use the formula I = Prt
I is the interest (unknown), P is the principal (1000), rate is the percent (unknown), and t is time in years (9/12).
9 months is a fraction of a year. There are 12 months in a year, so our fraction is 9/12. You can reduce this fraction by dividing by 3. The fraction reduced is 3/4. You can also use the decimal which is .75.
First we need to solve how much interest we earned. 1071.25 is the balance, so we need to subtract the principal from the balance.
1071.25 - 1000 = 71.25
Plug the numbers in to the formula. We are solving for r.
71.25 = 1000(.75)r
71.25 = 750r
71.25/750 = 750r/750
r = 0.095
Convert the decimal to a percent by moving the decimal two places right.
0.095 = 9.5%
Hey !!!
sinx = 3/5 ( given )
We know a formula of cos2x = ( 1 - 2sin²x)
putting the value of sinx on value of cos2x = ( 1 - 2sin²x)
hence,
we get
cos2x = ( 1 - 2sin²x )
=> [1 - 2 × ( 3/5 )² ]
=> [ 1 - 2 × 9 /25 )
=> [ 25 - 18 /25 ]
=> 7/25 Answer ✔

Answer:
I don't know if this what you want but I will explain how I think the answer is.
Step-by-step explanation:
a) You're at positive 5, and the integer explains that you're adding negative three spaces, which just means you go back three spaces. Your spot on the number line should be 2.
b) It says to go 3 spaces back from 5. Your spot on the number line will be two.
c) You're at negative 3, and you go another 5 spaces back. Your spot on the number line will be -8.
d) You're on -3 on the number line. You remove positive 5, so your new spot on the line is -8.
e) You're at -5. You're removing positive 3. Your going back three spaces. So you would be at -8.
Answer is D
TanB should be 4/3
here in the options it is 5/3 which is not true
