Answer:

63/8

Step-by-step explanation:

3 1/2 = 7/2

4 1/3 = 13/3

\frac{ \frac{7}{2} + 7 }{ \frac{13}{3}  - 3}

=  \frac{ \frac{21}{7} }{ \frac{4}{3} }

=  \frac{63}{8}

First Question:

Number of trapezoids - 6

Perimeter - 72

3 + 3 + 3 + 6 = <u>15</u>

3 + 3 + 3 + 3 + 6 + 6 = <u>24</u>

3 + 3 + 6 + 3 + 3 + 6 + 3 + 6 = <u>33</u>

15 + 24 + 33 = <u>72</u>

Second Question:

Number of cubes - 6

Surface area - 24 (probably 480 since it said <em>area</em>)

first cube - 6 ones

second cube - 8 ones

Third cube - 10 ones

you could do 6 + 8 + 10 = 24 or add up all the ones (1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1) and you will still get 24

(It said <em>area</em>, and area means to multiply so maybe its 6 x 8 x 10 = 480 and not 6 + 8 + 10)

Anyways have a good day/night :) I might be wrong, but I hope I helped at least a little

Suppose f and g are continuous functions such that g(6) = 6 and lim x → 6 [3f(x) + f(x)g(x)] = 45. Find f(6).
aleksandr82 [10.1K]
Since g(6)=6, and both functions are continuous, we have:

\lim_{x \to 6} [3f(x)+f(x)g(x)] = 45\\\\\lim_{x \to 6} [3f(x)+6f(x)] = 45\\\\lim_{x \to 6} [9f(x)] = 45\\\\9\cdot lim_{x \to 6} f(x) = 45\\\\lim_{x \to 6} f(x)=5


if a function is continuous at a point c, then lim_{x \to c} f(x)=f(c), 

that is, in a    c ∈  a continuous interval, f(c) and the limit of f as x approaches c are the same.


Thus, since lim_{x \to 6} f(x)=5, f(6) = 5


Answer: 5
