Step-by-step explanation:
The formula for percent change is
change/original.
So let's subtract 17 from 55 to find the change. 55-17=38
This is the change. Now we divide it by the original, 17.
38/17=2.235294
We're not done yet! We have to move the decimal point over to the right 2 spaces to make it a percentage. So, the percentage increase is
about 223.53 percent
Answer:
1300
Step-by-step explanation:
add 60x2+70+45x3
get 325
multaply times 4 because he gets this stuff then goes back and gets it 3 more times
get 1300
Answer:
The seventh root of a^5
Step-by-step explanation:

is equal to
![\sqrt[7]{a^5}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Ba%5E5%7D)
because
![b^{1/m} = \sqrt[m]{b}](https://tex.z-dn.net/?f=b%5E%7B1%2Fm%7D%20%3D%20%5Csqrt%5Bm%5D%7Bb%7D)
hope this makes sense and helps
Tan(theta) = 5/4
sin(theta)/cos (theta)=5/4
cos(theta)=4sin(theta)/5
sin²(theta)+cos²(theta)=1
sin²(theta)+16sin²(iheta)/25=1 /*25
25 sin²(theta)+16 sin²(theta)=25
sin²(theta)=25/41 /√
sin(theta)=
cos(theta)=
cot(theta)=
csc(theta)=1/sin(theta)=
sec(theta)=1/cos(theta)=
