Answer:
1)b=-4
2)k=4
3)can u explain what #3 and 4 say
4)?
5)0/ no solution
Step-by-step explanation:
First, change percent into decimal value
Percent means per hundred
APR = 3.5%
APR = 3.5/100
APR = 0.035
The APR is 0.035 of the total loan
Second, we need to find interest rate for 9 months
interest rate = 9/12 × 0.035
interest rate = 3/4 × 0.035
interest rate = 0.75 × 0.035
Third, determine what to put into calculator
She can put it like this
interest = interest rate × total loan
interest = 0.75 × 0.035 × 2,800
Or she can put it like this
interest = 0.02625 × 2,800
Answer:
4
Explanation:
1, 4, 16, 64......
mutiply all of the numbers by 4
1*4=4
4*4= 16
16*4= 64
Answer:
2 4/15 pints
Step-by-step explanation:
Caden has 3 2/3 pints of water in a pitcher.
He has 1 2/5 pints of water left in the pitcher.
The amount of water he poured is calculated as
3 2/3 - 1 2/5
3 - 1 + (2/3 - 2/5)
Lowest Common Denominator is 15
2 + (5 × 2 - 3×2/15)
2 + (10 - 6/15)
2 + (4/15)
= 2 4/15 pints
He poured 2 1/15 pints of water.
Answer:
There are no real factors for this.
Step-by-step explanation:
We could answer this either by checking each listed expression to see whether it is a factor of 9r^2-4r+1, or
We could take the coefficients of 9r^2-4r+1, determine the quantity b²-4ac (called the 'discriminant') and draw a conclusion based upon whether the discriminant is -, + or 0.
Let's use the 2nd approach.
Here, a = 9, b = -4 and c = 1.
Then the discriminant is b²2 - 4ac, or (-4)² - 4(9)(1), or 16 - 36.
Since 16 - 36 is negative, we conclude that this 9r^2 - 4r + 1 has NO REAL FACTORS.
