Answer:
○ C) 256 in.²
Step-by-step explanation:
{a}^{2} + 2a \sqrt{ \frac{ {a}^{2}}{4} + {h}^{2} } = S. A. \\ \\ {8}^{2} + 2(8) \sqrt{ \frac{{8}^{2}}{4} + {12}^{2}} = 64 + 64\sqrt{10}\\ \\ 64\sqrt{10} ≈ 266,3857703 ≈ 256

Answer:
y=3x+4
Step-by-step explanation:
first you find the slope by doing change in y over change in x. The change in y is 9 because 7-(-2)=9. The change in x is 3 because 1-(-2)=3. Then you do 9/3 which is 3, which is your slope, or m.
So now you know y=3x+b, then you substitute one of the points in for x and y, and you get 7=3(1)+b, where b is your y-intercept. then you solve, and find that b=4.
Now you put it into slope intercept form, which is y=mx+b, where m=3 and b=4, so you are left with y=3x+4.
Leave a thanks if I am correct please.
Answer:
7.5
Step-by-step explanation:
mean= sum all/number of all
(2+8+6+8+6+8+10+12)/8=
60/8=7.5
It takes them 12 seconds to eat the whole sausage.
<h3>What is speed?</h3>
Speed is the rate of change of distance.
Analysis:
If kitten eats x cm, then puppy will eat 14 - x cm
speed = d/t
speed of kitten = 1/2
speed of puppy = 2/3
1/2 = x/t
2/3 = 14 - x / t
t = 2x--------1
2t = 3(14 - x ) -------- 2
substitute t in equation 2
2(2x) = 3(14 - x)
4x = 42 - 3x
7x = 42
x = 42/7 = 6cm
substitute value of x in equation 1
t = 2(60 = 12 seconds.
In conclusion, it takes the both animals 12 seconds to finish the sausage.
