Answer:
u = (-21)/20
Step-by-step explanation:
Solve for u:
u + 1/4 = (-4)/5
Put each term in u + 1/4 over the common denominator 4: u + 1/4 = (4 u)/4 + 1/4:
(4 u)/4 + 1/4 = -4/5
(4 u)/4 + 1/4 = (4 u + 1)/4:
1/4 (4 u + 1) = -4/5
Multiply both sides of (4 u + 1)/4 = (-4)/5 by 4:
(4 (4 u + 1))/4 = (-4)/5×4
4×(-4)/5 = (4 (-4))/5:
(4 (4 u + 1))/4 = (-4×4)/5
(4 (4 u + 1))/4 = 4/4×(4 u + 1) = 4 u + 1:
4 u + 1 = (-4×4)/5
4 (-4) = -16:
4 u + 1 = (-16)/5
Subtract 1 from both sides:
4 u + (1 - 1) = (-16)/5 - 1
1 - 1 = 0:
4 u = (-16)/5 - 1
Put (-16)/5 - 1 over the common denominator 5. (-16)/5 - 1 = (-16)/5 - 5/5:
4 u = (-16)/5 - 5/5
-16/5 - 5/5 = (-16 - 5)/5:
4 u = (-16 - 5)/5
-16 - 5 = -21:
4 u = (-21)/5
Divide both sides by 4:
u = ((-21)/4)/5
5×4 = 20:
Answer: u = (-21)/20
Answer:
see below
Step-by-step explanation:
6+9x^2
Rewriting in decreasing powers of x
9x^2 +0x + 6
ax^2+bx+c
a = 9
b =0
c = 6
I think it is 10.
hope this helps!!! :D
60/100 / 60 are shaded out of the hundred. Simplified would be 3/5. The decimal would be 0.6.
The value of log(0.47) after rounding to 4 decimal place is -0.3279
Option D
Given :
Find the value of log(0.47) using calculator
To find the log value we use the calculator
here we are asked to find out log (0.47) that is the log (decimal)
we cannot find the log value without calculator because we have decimal argument inside log.
Use scientific calculator
Press log first then enter the number 0.47 inside a parenthesis
Press enter , it will show you the log(0.47)
log(0.47) =-0.327902142
Now round the answer to 4 decimal places
We have 0 in the 5th decimal place . so we keep 9 as it is
log(0.47) =-0.3279
