10^x=39 this is exponential form.
Answer:
= 2√3 m or 3.464
Step-by-step explanation:
Using the sine,
sin(60”) = x / 4 multiply both sides by 4
4 sin (60°) = x
4 * √3 / 2 = x
x = 2√3 m
slant height =2√3 m
Answer: The Z value for 95% confidence is Z=1.96.
Step-by-step explanation:
Answer:
x = 1
Step-by-step explanation:
Given
← factor numerator and denominator
= 
← cancel (x - 4) on numerator/ denominator
= 
The denominator of the rational expression cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.
x - 1 = 0 ⇒ x = 1 ← excluded value
[surface area of the square pyramid]=area of the base+4*[area of one lateral triangle]
area of the base=12²----> 144 cm²
area of one lateral triangle=b*h/2
b=12 cm
h=slant height -----> 15 cm
area of one lateral triangle=12*15/2-----> 90 cm²
[surface area of the square pyramid]=144+4*[90]----> 504 cm²
the answer is
the surface area of the square pyramid is 504 cm²
