What are the zeros of the function f(x)=-x^2+13x-36
Galina-37 [17]

For this case we have the following function:

f (x) = - x ^ 2 + 13x-36

To find the zeros of the function we make y = 0and solve for "x", then:

0 = -x ^ 2 + 13x-36

We multiply by -1 on both sides of the equation:

0 = x ^ 2-13x + 36

We factor the equation, for this we look for two numbers that, when multiplied, result in 36 and when added, result in -13. These numbers are -9 and -4.

(-9) * (- 4) = 36\\-9-4 = -13

Thus, the factored equation is:

(x-9) (x-4) = 0

Therefore, the roots are:

x_ {1} = 9\\x_ {2} = 4

Answer:

x_ {1} = 9\\x_ {2} = 4

Find how many quarts of 6% butterfat milk and 1% butterfat milk should be mixed to yield 75 quarts of 3% butterfat milk.
IgorC [24]

Answer:

30 gallons of 6% milk, and 45 gallons of 1% milk.

Step-by-step explanation:

x=quarts of 6% butterfat

<h2>First, write an equation.</h2>

0.06x+0.01(75-x)=0.03*75

<h2>Multiply both sides by 100.</h2>

0.06x*100+0.01*100(75-x)=100*0.03*75

<h2>Simplify</h2>

6x+75-x=3*75

6x+75-x=225

<h2>Solve</h2>

5x=225-75=150

5x=150

x=30

75-30=45

So, we need 30 gallons of 6% milk, and 45 gallons of 1% milk.
