C-7=7
Cancel out the -7 so add 7 to both sides
C-7=7
+7=+7
C=14
M-7=-7
Same thing
M-7=-7
+7=+7
M=0
X+5=-10
-5=-5
X=-15
Y+8=3
-8=-8
Y=-5
9k=-18
This time divide 9 on both sides
9k=-18
\9=\9
K=-2
-3v=-7
/-3=/-3
V=7/3
5n=-15
/5=/5
N=-3
T/2=-6
*2=*2
T=-12
D/-4=-2
*-4=*-4
D=8

Consider the given function and the given interval.

docker41 [41]

Answer:

(a) fave = 8

(b) c = 64/9

Step-by-step explanation:

(a) The average value of the function is its integral over the interval, divided by the width of the interval.

$f_{ave}=\displaystyle\frac{1}{16-0}\int_0^{16} {3x^{\frac{1}{2}}} \, dx=\left.\frac{x^{3/2}}{8}\right|_0^{16}=8$

(b) We want ...

f(c) = 8

3√c = 8 . . . . . use f(c)

√c = 8/3 . . . . . divide by 3

c = (8/3)² . . . . square

c = 64/9

(c) c ≈ 7.111

An animal shelter houses only cats and dogs, and there are 25% more cats than dogs. If there are 40 cats, how many dogs are ther

Inessa [10]

X is the number of dog
y is the number of cats , y=40
25% of x is 25*x /100=25x/100=x/4
<span>and there are 25% more cats than dogs means y+ x/4=x implies 40=(3/4)x
</span>x=160/3=53
so the number of dogs is 53 and the number of cats is 40
the total number is 53+40=93
