Answer:

p(t) = 0 for t = 1

p(t) = 1 for t = 1/8 = 8^-1

Step-by-step explanation:

the graph you will have to do yourself.

just go there and type in

-  log_{8}(x)

well, don't type "log" in letters.

you start by typing the "-" sign, and then you need to look up the functions by clicking on the "funcs" button and look for the log functions .

pick the

log_{a}

option. and then simply enter 8 as the first parameter in the {} brackets and x as the second in the () brackets.

and then you see.

any logarithm is 0 for x (or t) = 1.

because any a⁰ = 1.

and the logarithm gives you that exponent of the base number that leads to the given x value.

in other words : a logarithm is the inverse function of an exponential function.

the exponential function is

y = a^x

and the logarithm then determines

x =  log_{a}(y)

that is all.

and

-  log_{8}(x)  = 1

means that the logarithm itself delivered -1.

and 8^-1 = 1/8

so, p(t) = 1 for t = 1/8

Blizzard [7]

Answer:

Perimeter of the rectangle=Perimeter of the trapezium

2{(3x+4)+(4x)}=2(5x)+(x-3)+(7x-3)

→2(7x+4)=10x+x-3+7x-3

→14x+8=18x-6

→4x=14

→x=7/2

<u>→</u><u>x=3.5</u>

The value of x is <u>3.5 cm</u>

After getting 5 new rocks, George gave half of his rock collection to Susan. If George gave Susan 36 rocks, which equation could
kirill115 [55]
Let x be the number of rocks that George have at first.

First, George have x rocks. Then, he gets 5 new rocks. So, we have:
x + 5
Next, half of his rock collection is given to Susan.
\frac{x + 5}{2}

Susan got 36 rocks, so the equation is
\frac{x + 5}{2}  = 36
