Answer:

B) h(x) = -1/4(x - 6)(x + 3)

Step-by-step explanation:

Zeros of a function:

Given a polynomial f(x), this polynomial has roots x_{1}, x_{2}, x_{n} such that it can be written as: a(x - x_{1})*(x - x_{2})*...*(x-x_n), in which a is the leading coefficient.

In this question:

Concave down, so a < 0, which excludes options c and d.

Roots at x = 6 and x = -3. So

-\frac{1}{4}(x-6)(x-(-3)) = -\frac{1}{4}(x-6)(x+3)

So option B.

Answer:

The experimental subjects are pine tree seedlings .

Step-by-step explanation:

The physical entity to which the treatment is assigned at random is known as experimental unit .  

The same treatment cannot be received by two experimental units, they have to different treatments. The selection of experimental units plays an important role to determine the p-values in the statistical analysis. The experimental units are divided into different homogeneous groups called blocks.

From the question, the experimental subjects identified are pine tree seedlings.

What is the slope intercept from of the equation of the line that passes through (7, -5) and (3, -9)
never [62]

Answer:

B. y = x - 12

Step-by-step explanation:

First, find the <em>rate of change</em> [<em>slope</em>]:

\frac{-y_1 + y_2}{-x_1 + x_2} = m

\frac{5 - 9}{-7 + 3} = \frac{-4}{-4} = 1

Then use the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because you get it done faster that way. It does not matter which ordered pair you choose:

−9 = 3 + b

−12 = b

y = x - 12

________________________________________________________________________________________________

−5 = 7 + b

−12 = b

y = x - 12

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

I am joyous to assist you anytime.

How to do this question plz answer me ​
Karolina [17]

Answer:

x = 6 cm

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the height )

Here b = 12 and h = 4, then

A = \frac{1}{2} × 12 × 4 = 6 × 4 = 24 cm²

Then area of parallelogram = 3 × 24 = 72 cm²

The area (A) of a parallelogram is calculated as

A = bh ( b is the width and h the height )

Here b = x and h = 12, thus

12x = 72 ( divide both sides by 12 )

x = 6

The width of the parallelogram is 6 cm
