Answer:
The surface area of a square pyramid is the sum of the areas of all its 4 triangular side faces with the base area of the square pyramid. If a, h, and l are the base length, the height of the pyramid, and slant height respectively, then the surface area of the square pyramid = a2+ 2al (or) a2+2a √a24+h2 a 2 4 + h 2 .

Answer:
As the x-values go to negative infinity, the function's values go to positive infinity
Step-by-step explanation:
O As the x-values go to positive infinity, the function's values go to negative infinity. FALSE - it goes to positive infinity as we go to the right
O As the x-values go to zero, the function's values go to positive infinity FALSE- at zero the value is zero
O. As the x-values go to negative infinity, the function's values are equal to zero. FALSE - it goes to positive infinity as we go to the left
O As the x-values go to negative infinity, the function's values go to positive infinity TRUE - it goes to positive infinity as we go to the left
Answer:
Step-by-step explanation:
If your function is
, that is definitely not the answer you should get after taking the derivative implicitely. Rewrite your function to simplify a bit:
Take the derivative of x terms like "normal", but taking the derivative of y with respect to x has to be offset by dy/dx. Doing that gives you:
Collect the terms with dy/dx on one side and everything else on the other side:
Now factor out the common dy/dx term, leaving this:
Now divide on the left to get dy/dx alone:
Simplify each set of fractions to get:
Bring the lower fraction up next to the top one and flip it upside down to multiply:
×
Simplifying that gives you the final result:
or you could multiply in the x on the bottom, as well. Same difference as far as the solution goes. You'd use this formula to find the slope of a function at a point by subbing in both the x and the y coordinates so it doesn't matter if you do the distribution at the very end or not. You'll still get the same value for the slope.
25%of 32 should be written as 32•25%.then you convert 25%to a decimal wich is 25/100=0.25,last you multiply 32• .25=8 . 8 of them aregoldfish
