You didn't write the (-2/7) as a power; you were supposed to do b to the power of -2 over 7, which is what the other person done in your other post regarding this

Needd help please and thank you!! It’s 1/E just in case you couldn’t see that! Thx!

Answer:

option A

The base is e^-1

Step-by-step explanation:

Given in the question a function, f(x) = (1/e) $^{x}$

This function can also be write as.

f(x) = $(e^{-1})^{x}$

by using Negative Exponent Rule

$x^{-n}=\frac{1}{x^{n}}$

This says that negative exponents in the numerator get moved to the denominator and become positive exponents.

30=Five-sixthsY solve for Y

borishaifa [10]

Given :-

A linear Question is given to us .

The equⁿ is $\sf 30 = \dfrac{5}{6}y$

To Find :-

The value of y .

Solution:-

Taking the given equⁿ :

$\bf \implies30=\dfrac{5}{6}y$

$\bf \implies 30\times 6=5y$

$\bf\implies y=\dfrac{\cancel{30}\times6}{\cancel5}$

$\underline{\boxed{\red{\bf{\longmapsto \qquad y \qquad = \qquad 36 \qquad}}}}$

$\boxed{\green{\bf\pink{\dag}\: Hence\:the\:value\:of\:y\:is\:36.}}$

Some rules :-

On transposing numbers or variables,

Plus changes to minus.
Minus changes to plus .
Multiply changes to divide.
Divide changes to multiply.

Write the first five terms of a sequence. Don't make your sequence too simple. Write both an explicit formula and a recursive fo

Marina CMI [18]

Let the first five terms of a sequence be, 4,8,12,20,24

Ok, let me explain the meaning of term explicit and Recursive formula.

Explicit formula ,is the general formula to find any term of the sequence.

And, Recursive formula, is the method by which, we can find the nth term of the sequence if (n-1)th term of the sequence is known.

So,the explicit formula for the sequence is,

y = 4 n, where , n is any natural number.

And the recursive formula is .

y = 4 (n-1), with the help of (n-1)th term we can find nth term.

First term =4=4 × 1

Second term =8 =4 × 2

Third term =12=4×3

Fourth term =16 =4 × 4

.....................

...........................

.................................

(n-1) th term =4 × (n-1)

nth term =4 × n

Applying the simple procedure by looking at the first , second and the way the next term goes , the general and recursive formula is obtained.

As, you said you don't want simpler sequence

Consider the first five terms of the sequence, 0, 3,8,15, 24.

Explicit formula =n² + 2 n

Recursive formula=(n-1)²+2(n-1)

If,you will look at the sequence, it is neither Arithmetic nor geometric .

First term =0=0²+0×0

Second term =3=1+2=1²+2 × 1

Third term =8=4+4=2²+2×2

Fourth term =15=9+6=3²+2×3

Fifth term =24=16 +8=4²+2×4

So, Explicit formula= n²+ 2 n, where n is a whole number.

HOPE THIS HELPS!
