Parallel = same slope
f(x) = 4x + b
8 = 4(3) + b, b = -4
Equation: f(x) = 4x - 4
Answer:
The length is equal to 12 and the width is equal to 6.
Step-by-step explanation:
In order to find the values here, we start by setting the width equal to x. Now knowing this, we know that the length is twice that long. Therefore, the length would be equal to 2x. Now we can use the perimeter formula to solve the equation.
2L + 2W = P
2(2x) + 2(x) = P
4x + 2x = 36
6x = 36
x = 6
Now with the given value for x, we can tell that the width is 6 and then we multiply it by 2 to get the length value (12).
<span>Let
x = the 10s digit
y = the units
N1----------> original number
</span>N2----------> new number
<span>N2=N1+36--------- >N2-N1=36
y+x=8------------- > equation (I)
then
10x + y = N1
10y+x=N2
(10y+x)-(10x+y)=36- -----> 9y-9x=36------- > y-x=4----------- > equation (II)
resolving (I) and (II)
</span> y+x=8
y- x=4<span>
-----------------
2y+0x=12--------------- >y=6
then
x=8-y=8-6=2----------> x=2
N1=26 and N2=62
the two digit number is 26</span>
Hello,
y=-g/2 t²+25 t is the trajectoire with g=9.81 m/s²
y=-g/2 (t²-25*2/g t)
==>y=-g/2(t²-2*25/g t +25²/g²)+25²/g² * g/2
==>y=-g/2(t-25/g)²+25²/(2g)
==> h=25²/(2g)=625/(2*9.81*3.28084)=9,709479... feet
(for 1m=3.28084 feet)
