Answer:
(x, f(x)) = (1, 6), (2, 11), (3, 18), (4, 27)
Step-by-step explanation:
Each figure consists of two small squares and a square that has a side length of 1 more than the figure number. That is, ...
f(x) = (x +1)^2 +2
You can count the squares in figures 1-3. Figure 4 will be 2 more squares than 5^2 = 25, so will be 27 squares.
(x, f(x)) = (1, 6), (2, 11), (3, 18), (4, 27)
The equation is given to compute A(7) = A(r) pi r²
7 = pi r²
r² = 7/pi
value of pi = 3.14
so,
r² = 7/3.14
r = √ (7/3.14)
r = 1.49
Answer:
221
Step-by-step explanation:
Make a proportion.
182/14 = x/17
182 x 17 divided by 14 is 221
14,800=60x+16y
x+y=441
that implies y=441-x so
14,800=60x+16(441-x)
14,800=60x+16*441-16x
14,800-16*441=44x
7744=44x
x=176 kids and 441-176 adults
