Answer:

Step-by-step explanation:

This follows the form

y=a(b)^x

where a is the initial value and b is the base with the exponent.  Using that information, we can see that the initial value in our function is 1/3. Simplifying the base will take some work. Let's first rewrite this is a radical:

81^{\frac{3x}{4} }=\sqrt[4]{81^{3x} }

Now let's break up 81 into its factors. 81 is 9*9 which is 3*3*3*3.  Therefore,

81=3^4

We will use that as a simplification:

\sqrt[4]{(3^4)^{3x}}  which simplifies to

\sqrt[4]{3^{12x}}

Rewriting that as an exponent looks like this:

3^{\frac{12x}{4}} which simplifies to

3^{3x}

That's the answer for the second part.  The whole exponential equation now is

f(x)=\frac{1}{3}(3)^{3x}

The domain for an exponential function is all real numbers and the range is

y > 0

Number Two:
The formula to find the volume of a triangular prism is the area of the triangle/base multiplied by the height.
Finding the area of the base:
10×15=150×0.5=75
Now multiply it by its height.
75×25
1,875 m³
Number Four:
You need to multiply the width times the height times the length, or in any arrangements. Everything needs to get mutiplied together.

I only need the answer
irina [24]

Answer:

1

Step-by-step explanation:

The given equation of the function is y = -a·(x - h)² + 1

The positive constants of the equation = <em>a</em>, and <em>h</em>

The points the function crosses the x-axis = 2, and 4

Where the function crosses the x-axis, y = 0, and x = 2, and 4, therefore, when x = 2, we have;

y = 0 = -a·(2 - h)² + 1

When x = 4, we have;

0 = -a·(4 - h)² + 1

-a·(2 - h)² + 1 = -a·(4 - h)² + 1

-a·(2 - h)² = -a·(4 - h)²

(2 - h)² = (4 - h)²

±(2 - h) = +#±(4 - h)

When

(2 - h) is negative, and (4 - h) is positive, but the same magnitude, we have';

-(2 - h) = +(4 - h)

2·h = 4 + 2 = 6

h = 3

0 = -a·(4 - h)² + 1 = -a·(4 - 3)² + 1 = -a + 1

Therefore, a = 1

Durante a distribuição de bombons para seus netos, vovó Cláudia percebeu que, se distribuísse 11
Aleksandr [31]
<span>During the distribution of bonbons to her grandchildren, Grandma Claudia realized that if she distributed 11 chocolates for each of them, 10 candies would remain. In the meantime, distribute 13 chocolates each of his grandchildren, would lack 6. Based on this information, it is CORRECT to state that the difference between the number of candies and the number of grandchildren is A) 90. B) 30. C) -90. D) -30.

Let n=number of candies,
and c=number of grandchildren
The story expressed in modulo gives the two following equations:
then
mod(n,11)=10  (ten left if each given 11).............(1)
mod(n,13)=-6, or
mod(n,13)=7  (7 left if each given 13)

By enumerating (1), we have
10,21,32,43,54,65,76,87,98,109...
=> 8*11+10=98
By enumerating (2), we have
7,20,33,46,59,72,85,98,101...
=> 8*13-6=98
Hence there are 8 grandchildren and 98 candies.

The difference of the number of candies and the number of grandchildren is therefore 98-8=90.


Another way to get the number of grandchildren is
c=(10-(-6))/(13-11)=8
