the answer would be $45.55
<3
Step-by-step explanation:
20$ + $50.00 = $70
$70 - $6.95 = $64.5
$64.5 - $9.95 = $54.55
$54.55 - $20 = $34.55
$34.55 + $15 = $49.55
$49.55 - $4 = $45.55
Given nth term of an AP = 7-4n
Put n = 1 then t1 = 7-4(1) = 7-4 = 3
Put n = 2 then t2 =7-4(2) = 7-8 = -1
Common difference = t2-t1 = -1-3 = -4
First draw a line on the smallest number, and one on the largest. then calculate the midpoint (n+1)/2 the value, and draw that line in the middle. calculate upper quartile and lower quartile and draw lines on them. draw a line between the tops of the quartiles and one between the bottom, and from the middle of the lines to the minimum and maximum. sorry if not explained well
Answer:
4
Step-by-step explanation:
Answer:
p(2) = -9
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
p(x) = -2x³ + 4x - 1
p(2) is x = 2
<u>Step 2: Solve</u>
- Substitute: p(2) = -2(2)³ + 4(2) - 1
- Evaluate: p(2) = -2(8) + 4(2) - 1
- Multiply: p(2) = -16 + 8 - 1
- Add: p(2) = -8 - 1
- Subtract: p(2) = -9
