Answer:each book cost 39 dollars
Step-by-step explanation:
Since she had 16 dollars left over afterwords subtract 16 from 289 which leaves you with 273. then take the 273 and divide by the 7 books she bout whic will become 39 dollars therefore each book cost 39 dollars
A pyramid is regular if its base is a regular polygon, that is a polygon with equal sides and angle measures.
(and the lateral edges of the pyramid are also equal to each other)
Thus a regular rectangular pyramid is a regular pyramid with a square base, of side length say
x.
The lateral faces are equilateral triangles of side length
x.
The lateral surface area is 72 cm^2, thus the area of one face is 72/4=36/2=18 cm^2.
now we need to find
x. Consider the picture attached, showing one lateral face of the pyramid.
by the Pythagorean theorem:
thus,
thus:
(cm^2)
but
is exactly the base area, since the base is a square of sidelength =
x cm.
So, the total surface area = base area + lateral area =
cm^2
Answer:
cm^2
Since 24/6 = 4. So 4 is a integer, rational number, and whole number
Answer:
B. if F is a fuction then F(2+h)=f(2)+f(h)
Step-by-step explanation:
Answer:
f[g(4)] = 4
Step-by-step explanation:
Given table:
f[g(4)] is a composite function.
When calculating <u>composite functions</u>, always work from inside the brackets out.
Begin with g(4): g(4) is the value of function g(x) when x = 4.
From inspection of the given table, g(4) = -6
Therefore, f[g(4)] = f(-6)
f(-6) is the value of function f(x) when x = -6.
From inspection of the given table, f(-6) = 4
Therefore, f[g(4)] = 4
