W=L/2+4

W=(L+8)/2

A=LW, using W from above we get:

A=L(L+8)/2

A=(L^2+8L)/2, and we are told that A=234 so

(L^2+8L)/2=234

L^2+8L=468

L^2+8L-468=0  

L^2+26L-18L-468=0

L(L+26)-18(L+26)=0

(L-18)(L+26)=0, since L>0

L=18, and since W=(L+8)/2

W=13

So the length is 18 meters and the width is 13 meters.

If 10 to the power of x =<br> 5, what is x?
AleksAgata [21]

Answer:

x=0.5, or 1/2

Step-by-step explanation:

10^2 is 10*10*1. The 2 represents how many 10s are being multiplied together then multiplied by 1. That would mean that x has to be an amount of 10s to be multiplied together then multiplied by 1 to get 5. 1/2 of 10 is 5. The equation would be 10^1/2 which is equal to 1/2 of 10, or 5, multiplied by 1 because x is no more than one.

(0, -2) Correct or not?
8090 [49]
Make f(x) = y
f(x)= -1/8 (4) ^x+3 +6
y = -1/8 (4) ^x+3 +6
y-intercept is when the function crosses the y-axis, and the y-axis is always where x = 0
y = -1/8 (4) ^x+3 +6
y = -1/8 ( {4}^{0})+9 \\  {(anything)}^{0}  = 1 \\ y = -1/8 (1)+9 = 9 - (1 \div 8)  \\ = 8 \: (7 \div 8)
or was the equation instead:
y = -1/8 ( {4}^{(x + 3)})+6
???????
Because in that case it's totally different, so here goes...
y = -1/8 ( {4}^{(x + 3)})+6 \\ y = -1/8 ( {4}^{(0 + 3)})+6 \\ y = -1/8 ( {4}^{3})+6 \\ y = -1/8 (64)+6
y = -1/1 (8)+6 =  - 8 + 6 =  - 2
Therefore, yes it is correct that the y-intercept lies at the point (0, -2)

Suppose n=6 , m=2 , z1 is the average of the elements of x , and z2 is the average of the first three elements of x minus the av
rusak2 [61]

Answer:

See step by step explanations fir answers.

Step-by-step explanation:

Given that;

n=6 , m=2 , z1 is the average of the elements of x , and z2 is the average of the first three elements of x minus the average of fourth through sixth elements of x

So, Let d=n∧28, d′=n∧22.

We have nd=10, nd′=20n

so

n=10d=20d′nwhenced=2d′.

On the other hand, d is a divisor of 28, and above shows d′ is, too. As it is also a divisor of 22, the only possibilities are d′=1, d′=2, corresponding to d=2, d=4.

However, if d=2, n=20, and 20∧28=4, not 2. So the only solution is d=4, and n=40.
