Find an equivalent expression for the missing side length of the rectangle. Then find the missing side when x=3.Round to the nea

SashulF [63]

Answer:

Base of rectangle = 23.25 units (Approx.)

Step-by-step explanation:

Given:

Diagonal of rectangle (Hypotenuse) = 8x

Height of rectangle (Perpendicular) = 2x

Find:

Base of rectangle

Computation:

Base = √Hypotenuse² - Perpendicular²

Base of rectangle = √(8x)² - (2x)²

Base of rectangle = √64x² - 4x²

Base of rectangle = √60x²

Base of rectangle = 7.75x units (Approx.)

If x = 3

Base of rectangle = 7.75x

Base of rectangle = 7.75(3)

Base of rectangle = 23.25 units (Approx.)

Simplify this expression: cos theta/ tan theta cot theta

Dmitry_Shevchenko [17]

Q: $\frac{cos\theta}{tan\theta.cot\theta}=?$

A:

$\frac{cos\theta}{tan\theta.cot\theta}=cos\theta$

because... $tan\theta.cot\theta=1$
*********************************************************
Q: $\frac{cos\theta}{tan\theta}.cot\theta=?$

A:

$\frac{cos\theta}{tan\theta}.cot\theta&= \\ \\ \frac{cos\theta}{\frac{sin\theta}{cos\theta}}.\frac{cos\theta}{sin\theta}&= \\ \\ \frac{cos^2\theta}{sin\theta}}.\frac{cos\theta}{sin\theta}&= \\ \\ \frac{cos^3\theta}{sin^2\theta}}&= cos^3\theta.cosec^2\theta$

10. Write (2x + 1)(x - 3)(x - 2) in standard form.

Leto [7]

Answer:

$2x^3-9x^2+7x+6$

Step-by-step explanation:

The standard form of a polynomial is a method of writing a polynomial such that the terms are organized by degrees. In essence, the first term, or the left-most term has the highest degree or largest exponent. The right-most term or last term has the lowest degree or smallest exponent. One is given an expression in factored form. Distribute, multiply every term by another in the parenthesis, then simplify. Repeat this process until there are no more factored terms. Finally, rewrite the expression in standard form.

$(2x+1)(x-3)(x-2)$

Distribute,

$(2x+1)(x-3)(x-2)$

$((2x)(x)+(-3)(2x)+(1)(x)+(1)(-3))(x-2)$

Simplify,

$((2x)(x)+(-3)(2x)+(1)(x)+(1)(-3))(x-2)$

$(2x^2-6x+x-3)(x-2)$

$(2x^2-5x-3)(x-2)$

Distribute,

$(2x^2-5x-3)(x-2)$

$(2x^2)(x)+(-5x)(x)+(-3)(x)+(-2)(2x^2)+(-2)(-5x)+(-3)(-2)$

Simplify,

$(2x^2)(x)+(-5x)(x)+(-3)(x)+(-2)(2x^2)+(-2)(-5x)+(-3)(-2)$

$2x^3-5x^2-3x-4x^2+10x+6$

$2x^3-9x^2+7x+6$

This polynomial is already in standard form, thus there is no need to reorganize it. The leading term or the left-most term has the highest degree, three, the succeeding terms are in respective order of decreasing exponents.

What is the probability that you will not roll doubles when rolling two fair fifty sided dice (the sides are numbered 1-50 on ea

Nimfa-mama [501]

Sample space of two fair fifty sided dice = 50^2 = 2500
Probability of rolling a double = 50/2500 = 1/50
Probability of not rolling a double = 1 - 1/50 = 49/50
