Answer:
562.5ml
Step-by-step explanation:
using percentage multipliers you just have to do:
add 0.25 to 1 because that will make 125%
then multiply it by 450ml
450ml x 1.25 = 562.5ml
Answer:
Two numbers are 38 and 10
Step-by-step explanation:
Let x and y are the two numbers
One number is 18 more than twice the other number.
The sum of the numbers is 48.
Plug in y =2x+18
Subtract 18 from both sides
divide both sides by 3
x=10
Two numbers are 38 and 10
Answer:
f'(x) = 2[3tan²(x)sec²(x) - 10csc⁴(x)cot(x)]
Step-by-step explanation:
f' of tan(x) = sec²(x)
f' of csc(x) = -csc(x)cot(x)
General Power Rule: uⁿ = xuⁿ⁻¹ · u'
Step 1: Write equation
2tan³(x) + 5csc⁴(x)
Step 2: Rewrite
2(tan(x))³ + 5(csc(x))⁴
Step 3: Find derivative
d/dx 2(tan(x))³ + 5(csc(x))⁴
- General Power Rule: 2 · 3(tan(x))² · sec²(x) + 5 · 4(csc(x))³ · -csc(x)cot(x)
- Multiply: 6(tan(x))²sec²(x) - 20(csc(x))³csc(x)cot(x)
- Simplify: 6tan²(x)sec²(x) - 20csc⁴(x)cot(x)
- Factor: 2[3tan²(x)sec²(x) - 10csc⁴(x)cot(x)]
i got 180x + 9 but idk if it is the correct answer
