The area of a rectangular garden in square feet can be represented by 22 - 102 +21. The length is 2 - 7 feet. You have been hire
Anettt [7]

The area of a rectangular garden in square feet can be represented by z² - 10z +21. The length is z - 7 feet. You have been hired to fertilize the

garden. Recall that the area of the garden is z² - 10z +21. If z = 20 and the fertilizer costs $0.27 per square foot, how much it cost to fertilize

the garden?

Answer:

$ 59.67

Step-by-step explanation:

The area of a rectangular garden in square feet can be represented by z² - 10z +21 square feet

If z = 20

Therefore:

The area of the rectangular garden is:

20² - 10 × 20 + 21

400 - 200 + 21

= 221 square feet

The fertilizer costs $0.27 per square foot, how much it cost to fertilize

the garden?

The cost of fertilize the garden is calculated as:

1 square feet = $0.27

221 square feet = x

Cross Multiply

221 square feet × $0.27

=$ 59.67

Which function has the given properties below? The domain is the set of all real numbers. One x-intercept is (2 pi, 0). The ampl
Tomtit [17]

The functions y = -4sin (x) and y = 4sin (x) has the given properties.Functions help to define the relationship between the independent and the dependent variable.

<h3>What is function?</h3>

A expressions defining a connection between the independent variable and dependent variable is known as the functions.

A feature that:

The domain is defined as the set of all real numbers.

a single x-intercept

The amplitude is four.

The y-intercept is defined as (0,0)

Because the specified function goes through the functions having "cosine," the functions containing "cosine" can be omitted from the selections (0,0). As a result, we have two options:

Hence  y = -4sin (x) and y = 4sin (x) has the given properties.

The difference between the solutions to the equation x2 =a is 30 what is a ?
Mademuasel [1]
Given equation is x^2 = a

In general solution of x^2 = b is x = + \sqrt{b} and x = -  \sqrt{b}

So the solution of given equation is x = + \sqrt{a} and x = -  \sqrt{a}

Now difference between them is 30.
So we can write
\sqrt{a} - (- \sqrt{a}) = 30
\sqrt{a} +  \sqrt{a} = 30
2 \sqrt{a} = 30
\sqrt{a} = 15

On squaring both side
( \sqrt{a})^2 = (15)^2
a = 225
