Answer:
The correct option is d
The correct option is d
The correct option is c
the correct option is b
Step-by-step explanation:
The given equation is
The give interval is 
Now differentiating the equation
Therefore the equation is positive at the given interval
Now at x= 1
Now at x= 2
Now at the interval (1,2)
i.e
this tell us that there is a value z within 1,2 and
f(z) = 0
Which implies that there is a root within (1,2) according to the intermediate value theorem
Answer: A.
Step-by-step explanation: this is the answer because, look for keywords, in the sentence thay used the word WITHDREW which is also known as taking away, EX: withdrew= take away, divide, minus
Hope this helps!
Answer:
50
Step-by-step explanation:
because the total number of traingle =180 so we have 15 and 35 which equal 50 and the inside angle = 130 and x = 50
Answer:
<u><em>(x+5) is not a factor of f(x)</em></u>
Step-by-step explanation:
Step 1 : we solve the equation x +5 = 0
x + 5 = 0 then x = -5
Step 2: we plug in -5 into f(x)
If we get zero then x+5 is a factor of f(x)
If we get a number other than zero then x+5 is not a factor of f(x)
Calculation:
f(-5) = (-5)³ − 4(-5)² + 3(-5) + 7 = - 233
Since we got -233 and not 0
Therefore ,(x+5) is not a factor of f(x)
