Write the equation of a line in slope intercept form that has a slope of -2 and passes through the point (5,11).

VikaD [51]

Answer:

y = -2x + 21

Step-by-step explanation:

use point intercept form: y = mx + b where m is the slope and b is the y intercept

to find the y intercept, b, plug in values into equation and solve for b

11 = (-2) (5) + b

b = 21

then plug into the equation the slope and intercept!

In a building there are 30 cylindrical pillars. The radius of each pillar is 42 m and height is 7 m. Find the total cost of pain

SashulF [63]

Answer:

The total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter is Rs.554400.

Step-by-step explanation:

Given : In a building there are 30 cylindrical pillars. The radius of each pillar is 42 m and height is 7 m.

To find : The total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter ?

Solution :

Radius of each pillar r= 42 m

Height of each pillar h= 7 m

The curved surface area of each pillar is $CSA=2\pi rh$

Substitute the value,

$CSA=2\times \frac{22}{7}\times 42\times 7$

$CSA=1848\ m^2$

Area of 30 pillars is given by,

$A=1848\times 30=55440\ m^2$

The curved surface area of all pillars at the rate of Rs.10 per square meter.

The cost painting is $C=55440\times 10=Rs.554400$

Therefore, the total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter is Rs.554400.
