PLEASE HELP!!! Consider circle O, where m BD=70 and m CA=170

sveta [45]

BPD = 1/2(BD + CA)

BPD = 1/2(70 + 170)

BPD = 1/2(240)

BPD = 120

A full circle = 360 degrees

BC + AD = 360 - 70 - 170

BC+ AD = 360 - 240

BC + AD = 120

Diana paints 150 fence posts and chuck paints 130 fence posts. Diana paints 10 more fence posts than chuck. How many fence posts

statuscvo [17]

Complete Question

The complete question is shown on the first uploaded image

Answer:

Step-by-step explanation:

From the question we are told that

The relationship is $\frac{150 }{d} = \frac{130}{c}$

The number of fence post painted by chuck is $l = 130$

The number of fence post painted by Diana is $k = 150$

can paint 10 fences more than chuck so let say the of fence painted in an hour by chuck is $g$

Then the number of fence post painted by Diana in one hour is

$f = g+ 10$

$\frac{150 }{ g + 10 } = \frac{130}{g}$

$130 g + 1300 = 150g$

$g = 65 \ m$

Use the mean value theorem to determine the area of f(x)= 2x^2+3 on the interval [0 , 2]

Dafna1 [17]

Answer:

The area of given function is 5.67 unit²

Step-by-step explanation:

Given function f(x) as :

f(x) = 2 x² + 3

The interval in which f(x) lies [ 0 , 2 ]

Let The area for the curve = A

Or , A = $\frac{1}{b - a}\int_{a}^{b} f(x) dx$

Or, A = $\frac{1}{2 - 0}\int_{0}^{2} (2x^{2}+3) dx$

Or, A = $\frac{1}{2}(\int_{0}^{2} (2x^{2}) dx + \int_{0}^{2} 3 dx )$

or, A = $\frac{1}{2} [2( \frac{2^{3}-0^{3}}{3})] + \frac{1}{2}[3 (2-0)]$

or, A = $\frac{1}{2}$ ( $\frac{16}{3}$ + 6 )

Or, A = $\frac{1}{2}$ × $\frac{34}{3}$

∴ A = 5.67 unit²

Hence The area of given function is 5.67 unit² Answer
