Mr jones has a square that measures 10 feet on each side. He decides to expand the garden by expanding each day by x. Find the expression in standard form thay represents the area of the new expanded garden.

the expression in standard form that represents the area of the new expanded garden is_______. ​

Answers

Key Concepts

Area of a Rectangle

Formula: [tex]A=lw[/tex] where l is the length and w is the width

Whenever we modify any of the side lengths, as in make them longer or shorter, we simply add or subtract from l or w.

Standard Form

When a quadratic equation is organized in standard form, it follows the following format:

[tex]y=ax^2+bx+c[/tex] where a, b and c are numbers

In standard form, all the terms have been simplified and there are no parentheses to expand.

Solving the Question

We're given:

Square garden has measurements of 10 ft by 10 ftWe're expanding each side by xWe must find the area of the garden in standard form

If we're expanding each side by x, we're simply adding x to each side length:

10 ft by 10 ft ⇒ (x + 10) ft by (x + 10) ft

Now to find the area, we can use the area formula:

[tex]A=(x+10)(x+10)[/tex]

This expression can be simplified as l = w:

[tex]A=(x+10)^2[/tex]

Putting it into standard form:

We can do this by expanding the parentheses:

[tex]A=(x+10)^2[/tex]

⇒ Because this is a perfect square, we can use the following rule to help us expand this equation:

[tex](a+b)^2=a^2+2ab+b^2[/tex]

[tex]A=x^2+20x+100[/tex]

Answer

Therefore, the expression in standard form that represents the area of the new expanded garden is [tex]x^2+20x+100[/tex].

A comparison of the measures of central angles and inscribed angles of circles to their intercepted arcs are listed in the tables below. Based on the data in the tables, which conjecture about inscribed and central angles is true?.

Answers

A central angle means an angle that is at the center of a circle and whose legs are intersecting the circle.

What is a central angle?

Your information is incomplete as the data is not given. Therefore, an overview will be given.

Central angles are shaped by an arc between the two points. When a central angle and the inscribed angle intercept the same arc, then the central angle would be the double of the inscribed angles while the inscribed angle will be half of the central angle.

the table below shows the salary that ellen earned at her job based on her years of experience.

Which explicit formula can be used to determine the salary, f(n), that Ellen earned with n years of experience?

A: f(n)=4,350n+31,900
B: f(n)=4,350n+14,500
C: f(n)=725n+31,900
D: f(n)=725n+29,009

Answers

Answer:

Step-by-step explanation:

Find the difference between year 4 and year 5 salary.

32,625 - 31,900 = 725 (rate of change)

Multiply 4 x 725 then subtract that number from 31,900 to find out base salary

4x 724 = 2900

31,900 - 2,900 = 29,000

That's the constant.

So,

f(n) = 725n + 29,000

1.) Daniel stands on one side of a stream that is 400 feet wide. He wants to reach his campsite that is 1600 feet downstream on the opposite side. He decides he will swim to the boat ramp on the opposite side, which is part way downstream toward the campsite, then jog the rest of the way. The angle formed by Daniel’s swim path and the shore at the boat ramp is.

Is Daniel’s sister correct? Support your answer mathematically.
Answer: ?


(Please please do not answer if you aren't 100% sure of the answer!!)

Answers

From Daniel's initial location from the campsite given the width of the

stream is 400 feet and Daniel swims to the boat ramp, we have;

1.) Please find attached the drawing of the situation

2.) 3.34 minutes

3.) 1,298.59 feet

4.) 3.69 minutes

How can the distances and times be calculated?

1.) Please find attached a labelled diagram of the scenario created with MS Visio

2.) Daniel's average swimming rate (speed) = 150 feet per minute

[tex]The \ distance \ Daniel \ swims = \mathbf{\dfrac{400 \, feet}{sin(53^{\circ})}} \approx 500.85 \, feet[/tex]

The time it takes him to swim to the boat ramp, t, is therefore;

[tex]t \approx \dfrac{500.85 \ feet}{150 \ feet/min} \approx \underline{3.34 \ minutes}[/tex]

3.) The distance, d₁, downstream of the boat ramp from Daniel is given as follows;

d₁ = √((500.85 feet)² - (400 feet)²) ≈ 301.41 feet

Therefore;

The distance from the boat ramp to the campsite, d₂, is therefore;

d₂ ≈ 1600 feet - 301.41 feet = 1,298.59 feet

The distance from the boat ramp to the campsite, d₂ ≈ 1,298.59 feet                              

4. The time, t₂, it will take Daniel to jog from the boat ramp to the campsite is given as follows;

[tex]t_2 = \mathbf{\dfrac{d_2}{v_2}}[/tex]

Where;

v₂ = The rate at which Daniel can jog, which is 4 mph

Which gives;

[tex]t_2 = \mathbf{\dfrac{1298.59 \, feet}{4 \, mph}} = \dfrac{1298.59 \, feet}{4 \, mph} \approx \dfrac{1298.59 \, feet}{5.866142 \ feet/s} \approx \dfrac{221.37 \, s}{60 \, s/min} \approx 3.69 \, min[/tex]

Therefore;

The time it takes him to jog from the boat camp to the campsite, t₂ ≈ 3.69 minutes

Answers

Answer:

C. Add 13 to both sides of the equation.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, m. Add 13 to both sides of the equation:

m - 13 = 24

m - 13 (+13) = 24 (+13)

m = 24 + 13

m = 37
