Answer:

The shape of polygon is Nonagon.

Step-by-step explanation:

We need to find name of polygon whose number of vertex is one more than an octagon.

The number of vertex of octagon is 8 because total 8 side of octagon.

The number of vertex of required polygon is 1 more than 8

Thus, The number of vertex of required polygon is 8+1 = 9

The number of side of polygon is 2 fewer than a hendecagon.

The side of hendecagon = 11

The number of side of required polygon is 2 fewer than 11

Thus, The number of side of required polygon is 11-2 = 9

The number of side required polygon is 9 and number of vertex of polygon is 9.

Thus, It must be Nonagon because Nonagon has 9 sides and 9 vertex.

Solve for x. 6x2−2=13

makkiz [27]

Answer:

x = ±sqrt(5/2)

Step-by-step explanation:

6x^2−2=13

Add 2 to each side

6x^2−2+2=13+2

6x^2 = 15

Divide each side by 6

6/6x^2 = 15/6

x^2 = 5/2

Take the square root of each side

sqrt(x^2) = ±sqrt(5/2)

x = ±sqrt(5/2)

Which of the following is the inverse of y=3x?

shtirl [24]

Answer-

The inverse of $y=3^x$ is

$\boxed{\boxed{y=\log_3 x}}$

Solution-

The given function is,

$y=3^x$

We can get the inverse by interchanging he variable x and y among themselves and then separating each variables.

So in the inverse would be,

$\Rightarrow x=3^y$

Taking log of both sides,

$\Rightarrow \log x=\log 3^y$

As,

$\log a^b=b\times \log a$

Applying the same,

$\Rightarrow \log x=y\times \log 3$

$\Rightarrow y=\dfrac{\log x}{\log 3}$

As,

$\log_b a=\dfrac{\log a}{\log b}$

Applying the same,

$\Rightarrow y=\log_3 x$

Therefore, the inverse of $y=3^x$ is $y=\log_3 x$ .

Raoul saves $14.50 each month for 3 months. He puts his money in the bank and earns $0.33 interest . Hector puts \$3.60 e each w

Norma-Jean [14]

Answer:

$0.63

Step-by-step explanation:

Raoul saves $14.50 each month for 3 months. Total amount saved is 14.50 * 3 = $43.50

He earned an interest of $0.33.

The total amount of money he has is thus: 43.50 + 0.33 = $43.83

Hector puts $3.60 each week for 12 weeks. Total amount save by Hector is thus 3.60 * 12 = $43.2

Now we are asked to get how much money Raoul has. To get this, we simply subtract the amount of money Hector has from that of Raoul

That would be 43.83 - 43.2 = $0.63
