Answer:

2.5cm^2

Step-by-step explanation:

so diameter is basically radius*2...to find radius(since area of circle is pi*r^2 we need to divide diameter by 2)

so 1.8/2=0.9

now,

pi*0.9^2

pi*0.81

2.5 cm^2

Enter the coordinates of the vertex of the function f(x) = x2 + 4x - 7
elixir [45]

Given the equation of the function:

f(x)=x^2+4x-7

The given function represents a parabola

We will make a complete square to find the coordinates of the vertex

The coefficient of x = 4

Half the coefficient of x = 2

Square it give = 4

So, we will add and subtract 4

\begin{gathered} f(x)=x^2+4x+4-4-7 \\ f(x)=(x^2+4x+4)-11 \\ f(x)=(x+2)^2-11 \end{gathered}

Compare the last equation with the vertex form of the parabola

f(x)=(x-h)^2+k

So, h = -2, k = -11

So, the answer will be the coordinates of the vertex = (-2, -11)

Divide: (3x^4+11x^3+10x^2+5x-21) / ( x+3). Synthetic division is recommended, but you can use long division too
8_murik_8 [283]

Quotient Is 3x³+2x²+ 4x-7 and the remainder is 0.

<u>Step-by-step explanation:</u>

In long division, first we have to multiply (x+3) by 3x³, and then changing the sign of the product, cancel the terms then (x+3) is multiplied by 2x² then by 4x and finally by -7, we will get the remainder as 0 and the quotient as 3x³+2x²+ 4x-7.
