Question 12 information reference tables look at each expression. is it a factor of 8x4 + 2x2 – 45 when this expression is fully

vichka [17]

8x^4 + 2x^2 - 45 = (2x^2 + 5)(4x^2 - 9) = (2x^2 + 5)(2x + 3)(2x - 3)

(a) 2x^2 + 3....no
(b) 2x^2 + 5...yes
(c) 2x - 3....yes
(d) 4x^2 - 9)...no...not when it is fully factored

Answer:

Option no C

Step-by-step explanation:

Given:

Price of crackers $ 9 for 3 boxes

Price of Granola Bars $6 for 3 boxes

Total bought $ 20 worth of snacks

To find the equation

Solution:

Price of cracker $ 9 for 3 boxes

price of one box of a cracker = $ 9 / 3

=$ 3 per box

Price of granola bars $ 6 for 3 boxes

price of one box of a granola bars = $ 6 / 3

=$ 2 per box

Let total crackers bought are x

price of x crackers will be 3x

Let granola bars bought are y

price of y granola bars will be 2y

as total price is 20

so price of x crackes + y granolas = 20

which will be

3x + 2y = 20

which will be option no C

What is the value of tangent theta in the unit circle below? One-half StartFraction StartRoot 3 EndRoot Over 3 EndFraction Start

horrorfan [7]

Answer:

$\frac{1}{\sqrt{3} }$

Step-by-step explanation:

A unit circle is defined as a circle of unit radius (that is the radius of the circle is equal to 1). In trigonometry, the unit circle is a circle with a radius of 1, while centered at the origin (0, 0) in the Cartesian coordinate.

In the unit circle below, we can see that the line touches the unit circle at point $(\frac{\sqrt{3} }{2} ,\frac{1}{2})$ , therefore to find the tangent of theta, we use the formula:
