List x1, x2, x3, x4 where xi is the midpoint endpoint of the five equal intervals used to estimate the area under the curve of f

Amanda [17]

Answer:

$\bf x_1 = 2\\x_2 = 4\\x_3=6\\x_4=8$

Step-by-step explanation:

The given interval : x = 0 to x = 10

Length of interval = 10 - 0

= 10

$\text{Now, each }x_i \text{ is midpoint and endpoint of the five equal intervals}$

⇒ Number of equal intervals = 5

$\textbf{Length of each interval = }\frac{10}{5}$

$\textbf{Therefore, }\bf x_1 = 0 + 2 = 2\\x_2 = 2 +2 =4\\x_3=4+2=6\\x_4=6+2=8$

Points (1,3), (-4,7), and (-29,K) are collinear. Find K. How do i solve this?

oee [108]

Co linear points have same slope
Points (1,3), (-4,7), and (-29,K)
m1,2=7-3/-4-1=-4/5

m2,3=K-7/-29+4
m2,3=K-7/-25

-4/5=K-7/-25
4/5=K-7/25
4=K-7/5
20=K-7
K=27

Problem 1.1 Solve this equation: 2(x + 5) = 3x + 1

Tamiku [17]

Answer:

x = 9

Step-by-step explanation:

Distribute

2x+2*5=3x+1

2x+10=3x+1

Subtract 3x from both sides

-x+10=1

Subtract 10 from both sides

-x=-9

Multiply both sides by -1

x=9

55 is 40% of what number

Nutka1998 [239]

First of all, you must change 40% into a decimal by multiplying by 100⇒.40
Then you divide 55 by .40
55÷.40=137.5
Therefore, 55 is 40% of 137.5
