Step-by-step explanation:
step 1. if k is a zero then (x - 1) is a factor of 4x^3 + 23x^2 - 34x + 7.
step 2. we "can" use long division but synthetic division is easier!
step 3. 1 4 23 -34 7
4. 4. 27. -7.
4 27. -7. 0 (must get 0)
step 4. so the factors are (x - 1)(4x^2 + 27x - 7).
step 5. please note if you multiply these factors together you will get the original polynomial!
Explanation:
We already have phone A 5.3 cm
We just need to find phone B
First we need to find what one-third is as a decimal
Which is 0.3
Now add 0.3 to 5
0.3 + 5 = 5.3
Answer: neither phone a and Phone be 05.3 cm
Answer:
Step-by-step explanation:
Given
Required
Find x
The area is calculated as thus:
Substitute values
Multiply through by 2
Remove absolute sign
Add 6 to both sides
Divide by 3
<em>So, the coordinates are (-8, 11) or (12,11)</em>
Let h(t)= 0 (because when it reaches the ground h=0)
0=-16t^2+116
16t^2=116
divide both sides by 16
t^2= 7.25
square root both sides to find t
t=2.69sec
