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

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.

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

Answer:

25

Step-by-step explanation:

Area is found by doing two length x width. Because ethics is a square all side lengths are equal. Therefore I did the square root of 625 in order to determine what 2 numbers (length and width) would be multiplied by each other to get 625. Hope this helps

(n^2+7n+3n+21)/(n^2+7n-4n-28)-(3n/(n-4)

(n(n+7)+3(n+7))/(n(n+7)-4(n+7))-(3n/n-4)

Answer:

Step-by-step explanation:

340 - 120 = 220

220/20=11

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.

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.

We're given:

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

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

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

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;

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]

Answer: D

Step-by-step explanation:

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
