If the zeros are -2 and 3, then the factored form would be

(x+2) and (x-3)

-2+2 = 0 and 3-3 = 0

A polynomial is written as ax^2 + bx + c

Expand (x+2) (x-3) using FOIL: Multiply each tern in one set of parenthesis by each term in the other set and then simplify by combining like terms:

x*x + x*-3 + 2*x + 2*-3

x^2 -3x + 2x -6

Polynomial in standard form:

x^2 -x -6

Kite WXYZ is graphed on a coordinate plane. What is the area of the kite?

Misha Larkins [42]

Answer:

14 square units

Step-by-step explanation:

There are several ways we can find the area. Probably the easiest is to cut the kite in half vertically and find the area of each triangle. The area of the kite will be double that.

The height of the kite is 7 units, and the width is 4 units. So each triangle will have a base of 7 and height of 2.

A = 1/2 bh

A = 1/2 (7) (2)

A = 7

The area of the kite is double that, so:

2A = 14

What is the answer to this question please explain (picture included)

Yakvenalex [24]

Easy peasy
just use PEMDAS and some exonential laws

$(x^{m})(x^{n})=x^{m+n}$
$(x^{m})^{n}=x^{mn}$
$(ab)^{m}=(a^{m})(b^{m})$

also another is $x^{\frac{m}{n}}=\sqrt[n]{x^{m}}$

so

$[3(2a)^{\frac{3}{2}}]^{2}$ =
$(3^{2})((2a)^{\frac{3}{2}}^{2})$ =
$(9)((2a)^{\frac{3}{2}}^{2})$ =
$(9)((2a)^{\frac{6}{2})$ =
$(9)((2a)^{3})$ =
$(9)(8a^{3})$ =
$72a^{3}$

Suppose that z-scores come from a standard normal distribution. Use the Normal Probability Applet (Links to an external site.) t

Natalka [10]

Answer:

0.683

Step-by-step explanation:

We have to find P(-1<z<1).

For this purpose, we use normal distribution area table

P(-1<z<1)=P(-1<z<0)+(0<z<1)

Using normal area table and looking the value corresponds to 1.0, we get

P(-1<z<1)=0.3413+0.3413

P(-1<z<1)=0.6826

Rounding the answer to three decimal places

P(-1<z<1)=0.683

So, 68.3% of the z-scores will be between -1 an 1.
