Find the value of y...

soldier1979 [14.2K]

Answer:

y=0

Step-by-step explanation:

Rewrite Evaluate Powers:

3 $3^{2y-1}+3^{-1}+2*3^{y}*3^{-1}=1$

Calculate:

$(3^{y})^{2}*\frac{1}{3} +2*3^{y}*\frac{1}{3}=1$

Solve using substitution:

$(3^{y})^{2}*\frac{1}{3} +\frac{2}{3} *3^{y}=1$ $t=3^{y}$

Solve the equation for t:

$t^{2}*\frac{1}{3}+\frac{2}{3}t=1$

t=-3

t=1

Substitute back to t=3^y

3^y=-3

3^y=1

y∉R

$3^{y}=1$

y=0

Use grouping symbols and at least one exponent to write a numerical expression that has a value of 80.

Kaylis [27]

To group an expression, means that the factors of the expression are to be separated in (), [] or {}.

An expression with a value of 80 is: $2^2 \times ( [2 + 2] \times [3 + 2] )$

The number is given as:

$80$

Factorize

$80 = 2 \times 40$

Factorize 40

$80 = 2 \times 2 \times 20$

Express $2 \times 2$ as an exponent

$80 = 2^2 \times 20$

Express 20 as 4 x 5

$80 = 2^2 \times ( 4 \times 5)$

Express 5 as 3 + 2

$80 = 2^2 \times ( 4 \times [3 + 2] )$

Express 4 as 2 + 2

$80 = 2^2 \times ( [2 + 2] \times [3 + 2] )$

Hence, the above expression has a numerical value of 80

The area of a rectangle is 259 cm2 and its lenght is 18.5 cm find

crimeas [40]

The breadth of rectangle is 14 cm

The perimeter of rectangle is 65 cm

<em><u>Solution:</u></em>

Given that,

Area of rectangle = 259 square centimeter

Length of rectangle = 18.5 cm

<em><u>The area of rectangle is given by formula:</u></em>

$Area\ of\ rectangle = length \times breadth$

<h3><u>Find the breadth:</u></h3>

Substitute the given values in above formula:

$259 = 18.5 \times breadth\\\\breadth = \frac{259}{18.5}\\\\breadth = 14$

Thus breadth is 14 cm

<h3><u>Find the perimeter:</u></h3>

The perimeter of rectangle is given by formula:

$Perimeter = 2(length + breadth)$

Substitute the given values in above formula:

$perimeter = 2(18.5+14)\\\\perimeter = 2(32.5)\\\\perimeter = 65$

Thus perimeter of rectangle is 65 cm
