I need help please! I need to know what is/how to get a,b, and c for factoring trinomials of the problem (x-3)(x+4)=0.

1 answer:

6 0

Answer: Trinomials often (but not always!) have the form x2 + bx + c. ... So, how do you get from 6x2 + 2x – 20 to (2x + 4)(3x −5)? Let's take a look. Factoring Trinomials

Find f(1) if f(x)=5^x

dolphi86 [110]

Answer:

The value of function for x = 1 , y = 5 i.e f(1) is 5

Step-by-step explanation:

Given as :

f(x) = $5^{x}$

Now from the function the value of y depend on the value of x

So , for x = 1

I.e f(1) = $5^{1}$

Or, f(1) = 5

Hence The value of function for x = 1 , y = 5 i.e f(1) is 5 Answer

Len [333]

Answer:

<h2>12 feet 8 inch long cast a shadow</h2>

Step-by-step explanation:

A person 6 feet tall standing 18 feet away a lamppost cast a 9 foot shadow.

than move 4 feet than total distance is 22 feet

According to trigonometry rule make 30 degree angle

$tan\left ( 30\ \right )^{o}=\frac{p}{b}$

$\left ( \frac{1}{\sqrt{3}} \right )=\left ( \frac{x}{18+4} \right )$

$x\sqrt{3}=22$

than

$x=\frac{22}{\sqrt{3}}$

$=12feet$ $8 inch$ answer
