<span>The correct answer is 1.

Explanation:
The way this is written, everything after the words "divided by" would be calculated first; it is written as though this is a grouping, such as 20/(2*(5+5)). We would evaluate the innermost parentheses first; 5+5=10. Then this gives us 2*10=20 in our parentheses. 20/20 = 1.</span>

F(x)=(x+1)^(5)-5x-2 <br> Find F'(x) and zeros of F'(x)
KiRa [710]
Assuming you mean
f(x)=(x+1)^5-5x-2

first use chain rule on first part
derivitive of (x+1)⁵=5(x+1)⁴ times the derivitive of (x+1) which is 1
the first part is 5(x+1)⁴

derivitive of -5x is -5
derivitive of -2 is 0

we gots
f'(x)=5(x+1)⁴-5
find zeroes
0=5(x+1)⁴-5
5=5(x+1)⁴
1=(x+1)⁴
+/-1=x+1
-1+/-1=x
-2=x or 0=x

f'(x)=5(x+1)⁴-5
zeroes at x=-2 and x=0

Complete the square to make a perfect square trinomial. Write the result as a binomial square. q2−23q
tia_tia [17]

Answer:

\left(q-\dfrac{23}{2}\right)^2

Step-by-step explanation:

Given the expression: q^2-23q

To complete the square, we follow these steps:

Step 1: Identify the coefficient of q

Coefficient of q=-23

Step 2: Divide the coefficient of q by 2

=-\dfrac{23}{2}

Step 3: Square your result from step 2 and add it to the equation

This gives us: q^2-23q+\left(-\dfrac{23}{2}\right)^2

We have now completed the square.

Step 4: Write the result as a binomial square.

To write it as a binomial square, pick the variable and add the term in the bracket.

Therefore:

q^2-23q+\left(-\dfrac{23}{2}\right)^2=\left(q-\dfrac{23}{2}\right)^2

PtichkaEL [24]

Answer:

The father is 59

Step-by-step explanation:

lets say each of the kids are twelve

30*5=150-36=114=59+55

30*5+ 150 the age of everyone in the family added together

12*3= 36 the age of all the kids

150-36=114 the age of the adults added together

we know the mother is 4 years younger than the father so to state off you can take 114 and divide it by two to get what half of it is then take take numbers that are four apart to find the ages that add up to 114.
