A stainless steel patio heater is a square pyramid. The length of one side of the base is 22.2 in. The slant height of the pyram
Mice21 [21]

Answer:

<h2>The height is 87.5 in</h2>

Step-by-step explanation:

We can solve the height of a square pyramid using the Pythagoras theorem, this is because the slant height the height and the section of the base form a right triangle

the slant height is equivalent to the hypotenuse

the height is equivalent to the opposite

while the base(half) is the adjacent

Given

the base of the pyramid= 22.2 in

the adjacent is = \frac{22.2}{2} = 11.1 in

the slant height (hypotenuse)= 88.2 in

we know that Pythagoras theorem states that "The sum of the squares of the lengths of the legs of a right triangle ('a' and 'b' in the triangle) is equal to the square of the length of the hypotenuse ('c').

c^2=a^2 + b^2

hyp^2=opp^2+adj^2

substituting we have

88.2^2=opp^2+11.1^2\\opp^2= 88.2^2-11.1^2\\opp^2=7779.24-123.21\\opp^2=7656.03\\opp=\sqrt{7656.03} \\opp=87.498\\opp=87.50 in

If the cost of producing the product is 25,000 plus $5.00 per piece, then what is the cost equation for producing x items?
Alexus [3.1K]
If you mean it's $5 for each item and then you add $25,000 to it, then the equation would be
y=5(x)+25,000
let me know if that's what you were asking

Step-by-step explanation:

3m^2-3n^2= 3(m^2-n^2) = 3 (m+n)(m-n)

6m-6n= 6 (m-n)

3(m+n)~(m-n)~/6~(m-n)~ = (m+n)/2

mash [69]

Answer:

2 seconds and 38 seconds

Step-by-step explanation:

h=-16t²-vot

1,200=-16t²-640t

turn this into standard form

16t²-640t+1200=0

now plug thes numbers into the quadratice formula

a 16 b -640 c 1200

solve with quadratic formula to get ≅2 and ≅38 seconds
