Anna35 [415]
The decimal you put would be “two ten-millionths” if read out loud. If the allowable amount is 10 parts per billion, it would be 1 part per 100 million. Because 2 parts per 10 million is also 20 parts per 100 million, it is not not an acceptable amount

Given f(x)=4x^3+7x^2-7x-10 factor f(x), given that -1 is a zero
stira [4]
If - 1 is a zero then
(x + 1)
is a factor.

Dividing with this factor using the long division approach, we get the quadratic factor to be,

4 {x}^{2}  + 3x - 10
(see attachment).

We can rewrite the polynomial as
f(x) = (x  + 1)(4 {x}^{2}  + 3x - 10)

We can further factor as

f(x) = (x + 1)(4 {x}^{2}  - 5x + 8x - 10)
That is

f(x) = (x + 1)(x  +  2)(4x - 5)

Solve for g<br> 2h - 49 = 12
frez [133]

Answer: h = 30.5

Step-by-step explanation

2h - 49 = 12

     +49 +49

Add 49 to both sides. Inverse operation

2h = 61

2h/2 = 61/2

Divide 2 to both sides to get answer. Inverse operation

h = 30.5

Check:

2(30.5) - 49 = 12

       61 - 49 = 12

               12 = 12
