Here we are finding x, given the angle and adjacent side. To find x we will use the function cos as cos = a/h.

So let's do cos(35°) = 15cm / x

cos(35°) = 0.8 (1 dp)

x = 15 cm / cos(35°)

x = 18.3 cm (1 dp)

Janice attempted to shoot 34 free throws with a basketball. She made 19 of 1 point
vfiekz [6]

The experimental probability so far is 19/34, since she made 19 good shots out of 34.

So, based on this results, and until new updates arrive, we can assume that she makes point with probability 19/34.

Classify the following polynomials. Combine any
zavuch27 [327]

First simplify all polynomials and rewrite them in descending exponent order.

1. -x^2+2x

2. x^3-4x^2

3. -2x^2+2x+3

Now observe the terms with highest exponents in each expression, in particularly focus on their exponent value,

-x^2 with value of 2

x^3 with value of 3

-2x^2 with value of 2

The value is also known as order of polynomial and it is a way to classify polynomials.

Every order creates a <em>f</em><em>a</em><em>m</em><em>i</em><em>l</em><em>y</em> of polynomials determined by the order (which is always greater than -1)

A polynomial such as (1) and (3) have an orders of 2, which is often called quadratic order and thus the polynomials (1), (3) are classified in the same <em>family</em> of quadratic polynomials, these are polynomials with order of 2.

Polynomial (2) however has an order of 3, which is called cubic order. This polynomial (2) is classified in the family of cubic polynomials.

There are of course many other families, in fact, infinitely many of them because you have order 0, 1, 2, 3, and so on there are precisely \aleph_0+1 read as "aleph 0 + 1" (the number of natural numbers + 1 (because 0 is not a natural number)) of polynomial families.

The first few have these fancy names, for example:

order 0 => constant polynomial

order 1 => linear polynomial

order 2 => quadratic polynomial

order 3 => cubic polynomial

order 4 => quartic polynomial

and so on.

Hope this helps!

Use substitution to solve the system of equations<br> Y+x=3<br> Y=1.5x+1
Serjik [45]

The solution to given system of equation is (x, y) = (0.8, 2.2)

<em><u>Solution:</u></em>

<em><u>Given system of equations are:</u></em>

y + x = 3 --------- eqn 1

y = 1.5x + 1 ---------- eqn 2

We have to solve the above system of equations by substitution method

<em><u>Substitute eqn 2 in eqn 1</u></em>

1.5x + 1 + x = 3

Combine the like terms

2.5x + 1 = 3

Move the constants to Right hand side of equation

2.5x = 3 - 1

2.5x = 2

x = 0.8

<em><u>Substitute x = 0.8 in eqn 2</u></em>

y = 1.5(0.8) + 1

y = 1.2 + 1

y = 2.2

Thus the solution to given system of equation is (x, y) = (0.8, 2.2)
