Answer:

120x^3y^7

We can use the Pascal's triangle to solve this question.

This pascal's triangle is shown in the Image below. To build the triangle, begin with the number 1 at the top, then continue placing numbers below it in a triangular pattern. In this way, each number are the numbers directly above added together. So, the expression is :

(x+y)10

After you do the steps you be left with:

120x^3y^7

Find the equation of the quadratic function with vertex (-2,18) passing through (-5,0)?
Sliva [168]

Answer:

y-18=-2(x+2)^2

Step-by-step explanation:

Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

y-k=a(x-h)^2

Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.

It's been given the vertex of the parabola as (-2,18):

y-18=a(x+2)^2

Now substitute the point (-5,0) and find the value of a:

0-18=a(-5+2)^2

Operating:

-18=a(-3)^2

-18=9a

Solving for a:

a = -18 / 9

a = -2

Thus, the equation of the quadratic function is:

\mathbf{y-18=-2(x+2)^2}

F(x) = 3^x; find f(0)​
spin [16.1K]

Answer:

f(0)=1

Step-by-step explanation:

The question asks us to find f(0). We want to find what f(x), or y is, when x is equal to 0.

f(x)=3^x

Therefore, we can substitute 0 in for x.

f(0)=3^0

Evaluate the exponent, 3^0.

Any number raised to the power of zero is equal to 1.

f(0)=1
