Answer:
8.72×10²
Step-by-step explanation:
- 8.72×10²=872
The simplified expression is (r
) (4
x s³) is 4r³.
<h3>What are exponents?</h3>
The amount of times a number has been multiplied by itself is shown by its exponent. The result of multiplying 8 by itself n times is represented as follows:
8 x 8 x 8 x 8 x …..n times = 8n
Given:
(r
) (4
x s³)
Now, using the law of exponents we have

So,
(r
) (4
x s³)
= 4
x 
= 4r³ x s°
= 4r³
Hence, the simplified expression is (r
) (4
x s³) is 4r³.

What picture are you talking about ?
Answer:
Step-by-step explanation:
This form is already factored so it can help us to find the intercepts with the x-axis
how ?
- The intercepts with the x-axis are simply the points where f(x)=0
from the factored form we can deduce that x=2 and x=3 are the points that represent the intercepts with the x-axis since f(2)=0 and f(3)=0
- The intercept with the y-axis is the image of 0 so f(0)=(0-2)(0-3)=6
so :
- The intercepts with the x-axis are (2,0) and (3,0)
- The intercept with they-axis is (0,6)
To get the standard form we should develop :
= x²-5x+6
now the vertex form with the axis of symmetry :
- There are many ways to do it but here is the simplest one :
the standard form is x²-5x+6 :
The coordinates of the vertex are : (
,f(
) )
- let A be the vertex : a(
,
) - the axis of simmetry is x= 5/2
- The vertex form is : 1*(x-
)²/(1/4)
