Answer:

y = -4x + 4

Step-by-step explanation:

y = (1/4)x - 1

m = (1/4)

Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/4)

$= (-1)*\frac{4}{1}\\\\=-4$

(3 , -8)

y - y1 =m(x -x1)

y -[-8] = -4(x - 3)

y + 8 = -4x + 12

y = -4x + 12 - 8

y = -4x + 4

A length of chain is to be constructed by placing 36 component links end to end. The length of a link produced by a production p

Setler79 [48]

Answer:

d. 90 cm, 1.2 cm

Step-by-step explanation:

Given that:

The sample size n = 36

For the length of the link:

The mean $\overline x$ = 2.5

The standard deviation s = 0.2 cm

In a chosen 36 links, The mean and standard deviation for the length chain is as follows:

Mean = n $\overline x$

Mean = 36×2.5

Mean = 90 cm

The Standard deviation = s×√n

The Standard deviation = 0.2×√36

The Standard deviation = 0.2×6

The Standard deviation = 1.2 cm

An angle of 90° measures (___) Pi radians. An angle of -pi/5 radians measures ____? °.

a_sh-v [17]

$\huge \bf༆ Answer ༄$

Conversion from degree to radian ~

$\boxed{ \sf{ \frac{\pi}{180} \times \theta }}$

$\sf \dfrac{\pi}{180 } \times 90$

$\sf \dfrac{\pi}{2} \: \: rad$

Conversion from radians to degree ~

$\boxed{ \sf{ \frac{180}{\pi} \times \theta}}$

$\sf \dfrac{180}{\pi} \times - \dfrac{ \pi}{5}$

$\sf - 36 \degree$
