Simplify 81^5=3^w and find w

Mathematics
1 answer:
Allisa [31]3 years ago
8 0

Answer:

w = 20

Step-by-step explanation:

<u>Step 1:  Find common bases</u>

81^5 = 3^w

81 → 3 * 3 * 3 * 3 → 3^4

Therefore, 81 = 3^4

81^5 → 3^(^4^)^*^5 → 3^2^0

So... 3^2^0 = 3^w

Since same base now, we can evaluate the exponents by themselves.

20 = w

Answer:  w = 20

Two triangles have the same heights. One triangle has a base length that is twice the base length of the other triangle. Are the
djyliett [7]

Answer:

Yes

Step-by-step explanation:

The formula for area of a triangle is A = (1/2)bh,

For the first triangle we can leave it in general terms, so it's area is

A = (1/2)bh, depending on what b and h are, but it doesn't matter here...

The second triangle has base that is twice the other triangles base.  Bases being multiples of each other is the definition of being proportional so the bases are proportional, an the area of the second triangle is

A = (1/2)(2b)h,   which simplifies to

   A = bh

Comparing the 2 areas, you can see that one has a multiplier of (1/2), so their areas are proportional

Graph the line with slope 3/2<br> and y-intercept - 7.
Ronch [10]

Answer:

14=3x-2y

y = m x+ c \\ y =  \frac{3}{2} x - 7 \\ y =  \frac{3x - 14}{2}  \\ 2y = 3x - 14 \\ 14 = 3x - 2y \\ therefore \\ 14 = 3x - 2y \: is \: the \: required  \: eqution \: of \: the \: line

it can be wrong also

Es un número disminuido en cuatro su resultado es ocho
NARA [144]

Resolviendo una resta, veremos que el número es igual a 12.

<h3>¿Como encontrar el número?</h3>

Definamos X como nuestro número, sabemos que cuando este número es disminuido en cuatro (es decir, le restamos 4 a nuestro número X) el resultado es 8.

Entonces, lo que tenemos que hacer es resolver la operación:

X - 4 = 8

Para resolver esto, lo que tenemos que hacer es sumar 4 en ambos lados de esta ecuación, asi obtenemos:

X - 4 + 4 = 8 + 4

X = 12

De esta forma, concluimos que nuestro número es igual a 12.
