Answer:

160/3 degrees

Step-by-step explanation:

(80/3) ×2 =160/3 degrees

80 divided by 3 which mean 80 divides into 3 parts.

We get 2 parts of the 80, so that we times 2.

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

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

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

Please help asap im super confused<br> Which is the equation for BC?

Aloiza [94]

Points on BC:
(-5, 5) and (0,1)
Slope = (5-1)/(-5-0)
Slope = -4/5

y = mx + c
y = -4/5x + c

at point (0,1)
1 = -4/5(0) + c
c = 1

y = -4/5x + 1
5y = -4x + 5
4x + 5y = 5 (Answer D)

The slope of the line below is -2. Use the coordinates of the labeled point to

nika2105 [10]

Answer:

$y + 6 = -2(x - 4)$

Step-by-step explanation:

Given:

Slope (m) = -2

Point on the line = (4, -6)

Required:

Point-slope equation of the line

Solution:

Point-slope equation takes the following form:

$y - b = m(x - a)$ ,

Where,

m = slope of the line = -2

(a, b) = coordinates of the point on the line. = (4, -6)

Plug in the values into the slope-point equation

$y - (-6) = -2(x - 4)$

$y + 6 = -2(x - 4)$
