3.)

∠1 = 60°

∠2 = 180° - 70° - 60°

= <u>5</u><u>0</u><u>°</u> (A)

4.)

∠3 = 180° - 40° - 60°

= 80°

∠4 = 180° - ∠3

= 180° - 80°

= <u>1</u><u>0</u><u>0</u><u>°</u> (H)

5.)

<u>ΔABC = ΔCBD</u> (B)

Reason :

ΔABC --> the angle is at B

ΔCBD ---> the angle is at B

A company's revenue from selling x units of an item is given as R=1700x-2x^2 . If sales are increasing at the rate of 25 units p

viva [34]

Answer:

The daily rate is: 17500 units per day

Step-by-step explanation:

Given

$R = 1700x - 2x^2$

$\frac{dx}{dt} = 25$

Required

Find $\frac{dR}{dt}$ when $x = 250$

We have:

$R = 1700x - 2x^2$

Differentiate both sides with respect to time

$\frac{dR}{dt} = 1700\frac{dx}{dt} - 4x\frac{dx}{dt}$

Factorize

$\frac{dR}{dt} = (1700- 4x)\frac{dx}{dt}$

Substitute: $\frac{dx}{dt} = 25$ and $x = 250$

$\frac{dR}{dt} = (1700- 4x)\frac{dx}{dt}$

$\frac{dR}{dt} = (1700- 4*250)*25$

$\frac{dR}{dt} = (1700- 1000)*25$

$\frac{dR}{dt} = 700*25$

$\frac{dR}{dt} = 17500$

Which numbers are a distance of two units from eighths on a number line?

Irina-Kira [14]

Answer:

$\Huge \boxed{\mathrm{-1.875 \ and \ 2.125}}$

$\rule[225]{225}{2}$

Step-by-step explanation:

Eighths is 1/8 or 0.125.

Two units of distance from 0.125 can be :

$0.125-2=-1.875 \\\\\\ 0.125+2=2.125$

$\rule[225]{225}{2}$
