What is the ratio of the perimeter of the smaller triangle to the perimeter of the larger triangle?

Andrews [41]

Answer:

Option C. $\frac{5}{6}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

and

The scale factor is equal to the ratio of its corresponding sides

Let

z-----> the scale factor

$z=\frac{15}{18}$

simplify

$z=\frac{5}{6}$

On a particular afternoon, a student plans to take her niece to a movie followed by dessert. The possibilities for the movie are

Sergio039 [100]

Answer:

12 possibilities

Step-by-step explanation:

The number of different possibilities for the afternoon events is determined by the product of the number of movie choices (3: animated, comedy and adventure) by the number of possible deserts (4: hot fudge sundae, strawberry shortcake, apple pie and chocolate milkshake):

$n = 3*4\\n=12\ possibilities$

There are 12 different possibilities.

I really need help with this, lol: Using the table of values given, determine the equation of the function that would model this

Oduvanchick [21]

Somewhat optimistically, we guess that this function is a polynomial, since it doesn't immediately look like it follows an exponential or logarithmic pattern.

We can solve for the equation of degree $n$ passing through $n$ points by writing the polynomial in the form:

$c_n x^n + c_{n-1} x^{n-1} + \cdots + c_0 = f(x)$ .

Then, we solve for the values of the sequence $c$ by substituting in $n$ pairs $(x, f(x))$ . This gives us the polynomial of degree $n$ satisfying the conditions for the first $n$ points; afterwards, we have to check if this polynomial works for the other points. If it does, it is the solution, otherwise, we need to keep going.

Testing in this manner, degrees zero, one, and two don't work. When we try degree three, however, we get the system of equations:

$c_3+c_2+c_1+c_0=0$
$8c_3+4c_2+2c_1+c_0=3$
$27c_3+9c_2+3c_1+c_0=16$
$64c_3+16c_2+4c_1+c_0=45$

Solving this system gives $c_3 = 1, c_2 = -1, c_1 = -1, c_0 = 1$ . Substituting $5$ into this polynomial, $5^3-5^2-5+1=96$ . Likewise, $f(6) = 175$ , so this polynomial satisfies all of the conditions listed.

We therefore conclude that $f(x) = \boxed{x^3-x^2-x+1}$ .
