Answer:

$P(x) = 16x - 100 - 0.1x^2$

Step-by-step explanation:

Given

$R(x) = 46x$

$C(x) = 100 +30x +0.1x^2$

Required

Determine the profit function

This is calculated as follows:

$P(x) = R(x)- C(x)$

Substitute values for R(x) and C(x)

$P(x) = 46x - (100 + 30x + 0.1x^2)$

Open bracket

$P(x) = 46x - 100 - 30x - 0.1x^2$

Collect like terms

$P(x) = 46x - 30x - 100 - 0.1x^2$

$P(x) = 16x - 100 - 0.1x^2$

Answer:

x = 82°

y = 59°

z = 39°

Step-by-step explanation:

∠x = 1/2(134° + 30°) = 82°

∠z = 180° - 59° - 82° = 39°

arc DF = 2(39°) = 78°

arc DB + arc DF = 134° + 78° = 212°

draw a diameter down from point B to the opposite side of the circle, call that point P:

arc BDP = 180°

(arc BDF) 212° - 180° = 32° (arc PF)

∠PBG = 1/2(32°) = 16°

∠DEB = 1/2(134°) = 67°

∠DBE = 180° - 59° - 67° = 54°

(∠DBE) 54° - (∠z) 39° + (∠PBG) 16° = (∠PBE) 31°

y = 90°- 31° = 59°

Y=6x/5 +27 find y-intercept and slope

mixas84 [53]

Answer:

General equation of a line is given by y = mx +c, where m is the gradient /slope, c is the intercept. To find for the intercept on y- axis, put x = 0.
$y = \frac{6(0)}{5 } + 27 \\ y = \frac{0}{5} + 27 \\ y = 27 \\ therefore \: the \: intercept \: on \: y \: is \: 27 \\$
By comparison,
$y = mx + \: c \\ y = \frac{6}{5} x \: +27 \\ m = \frac{6}{5 \: } \: \\ hence \: slope \: is \: \frac{6}{5}$
