Answer:

Step-by-step explanation:

[ -t² + 5t² - 6t] + [8t² - 8t] =  -t² + 5t² - 6t + 8t² - 8t  

 {bring the like terms together}

= -t² + 5t² + 8t² - 6t - 8t   {add/subtract the like terms}

= 12t² - 14t

Describe how the graph of y=log (10 000x) is related to the graph of y=log x
Nana76 [90]
Background: log (a . b) = log a + log b 
hence log(10000x) = log 10000 + log x but we know that log 10000 = 4
                               = 4 + log x 
therefore the graph of log(10000x) is just the graph of log x transposed by 4

A cylinder has a surface area of 224 pie square meters and a diameter of 14 meters. Find the height of the cylinder.
inna [77]

Answer: 9 meters

Step-by-step explanation:

Hi, to answer this question we have to apply the formula:

Surface area if a cylinder (S)= 2 π r2 + 2 π r h

Where r is the radius and h is the height

Diameter is equal to 2r , so in our case:

14 =2r

r = 14/2 = 7 meters

Replacing with the values given and solving for h:

224 pi = 2 π 7^2 + 2 π 7 h

224 π - 2 π 7^2 / 2 π 7= h

703.71 -307.87 /43.98 = h

9 = h
