The weekly production cost C of manufacturing x watches is given by the formula C = 6000 + 3x, where the variable C is in dollar

Irina18 [472]

Answer:

therefore, to produce 1000 watches , it would cost 9000 dollars.

Price : 9 dollars a watch

Step-by-step explanation:

C=6000 + 3x

what is the cost of producing 1000 watches?

first do this

C= (1000)= 6000 + 3(1000)

C= (1000)= 6000 +3000

C= 9000

A circle has a radius of 8cm. An angle of 1.4 radians is subtended at the center by an arc. Calculate the length of the arc

AURORKA [14]

Answer:

11.2 cm

Step-by-step explanation:

Given that;

Arc Length Formula (if θ is in radians): l = ϴ × r

ϴ = angle subtended in radians

r= radius of the circle

l = 8cm × 1.4 radians

l= 11.2 cm

Solve the equations 1. 16x^2-1=0 2. 36z^2 96z 15=0

Allisa [31]

$16x^2-1=0 2$

$16x^2-1=0 2:x$

$
16x^2=1
 
$ $|Add \ 1 \ to \ both \ sides|$

$x^2= \dfrac{1}{16}$ $|Divide \ both \ sides \ by \ 16|$ 

$x^2= \sqrt{\dfrac{ \sqrt{1}}{ \sqrt{16}}}$ $|Take \ the \ square \ root \ of \ both \ sides|$

$x= \dfrac{1}{4}$
