Assuming the cylinder is closed at both ends

S A = 2 pi r^2 + pir^2h
= 2 pi 6^2 + pi 6^2 24
= 226.2 + 2714.3
= 2940.5

If the cyilnder is open at both ends the surface area is 2714.3

Write the equation of a line that is perpendicular to x=3x=3x, equals, 3 and that passes through the point (0,-4)(0,−4)left pare

leva [86]

Answer: $x+3y=12$

Step-by-step explanation:

Slope of two lines that are perpendicular to each other is 1.

If one line is $y=3x$ , then its slope = 3 [by comparing to the linear equation y= mx+c, here m=3]

Let n be the slope of the required line, then

$n\times3=-1\\\\\rightarrow\ n=\dfrac{-1}{3}$

Equation of line with slope n and passers through (a,b) is

$(y-b)=n(x-a)$

Equation of line with slope n= $\dfrac{-1}{3}$ and passes through point ( 0,-4) :

$(y-(-4))=\dfrac{-1}{3}(x-0)\\\\\Rightarrow\ y+4=\dfrac{-1}{3}x\\\\\Rightarrow\ -3(y+4)=x\\\\\Rightarrow-3y-12=x\\\\\Rightarrow x+3y=12$

Hence, Required equation : $x+3y=12$

An owner of Honda City car sells his car at a price of RM 7.50,000 with a loss present of 12.5%. Then find the price at which he

Mars2501 [29]

Answer:

Cost = RM 857143

Loss = RM 107143

Step-by-step explanation:

Given:

Selling price SP = RM 750000
Loss% = 12.5
Cost price CP = x

Cost price is found as:

SP = CP - 12.5%
750000 = x - 12.5%
750000= x*(100-12.5)/100
750000= 0.875x
x= 750000/0.875
x≈ RM 857143

Loss is:

RM 857143 - 750000 = RM 107143

Dishwashers are on sale for 25% off the original price (d), which can be expressed with the function p(d) = 0.75d. Local taxes a

shutvik [7]

We are given the functions:

P (d) = 0.75 d ---> 1

C (P) = 1.14 P ---> 2

The problem asks us to find for the final price after discount and taxes applied; therefore we have to find the composite function of the two given functions 1 and 2. To solve for composite function of the final price of the dishwasher with the discount and taxes applied, all we have to do is to plug in the value of P (d) with variable d into the equation of C (P). That is:

C (P) = 1.14 (0.75 d)

C (P) = 0.855 d

C [P (d)] = 0.855 d

Is ABC=XYZ? PLEASE HELP!!

statuscvo [17]

Yes ur correct
ABC=XYZ

Because C and Z stay the same so just flip the shape n point A is small and X is small so they go together and B and Y r pointing out they go together
