Help me anyone??? Would be nice!

Answer:

Area is 50 meters squared

Step-by-step explanation:

So you know that length = 10 meters and width is half of the length.

You need to make an equation to solve for width, 'W', using length, 'L'

W = L / 2

Now just plug in length

W = 10 /2 = 5

Since you know length and width now, you can solve for area

Area = W * L

Area = 5 * 10

Area = 50

Answer:

I think it's division property and x = 6

Answer:

(4,4)

Step-by-step explanation:

There are two ways that you can solve this. You can solve it with the help of technology or you can solve it traditionally. I will show how to do it in both ways so you can pick which way you want to solve it.

Traditional Method:

5x - 2y = 12

6x + 2y = 32

Look at the variables and numbers in both equations. One of them has to be the same value but have to have opposite signs. The 2y in both equations are the same value but have different signs. That's what we want. We can add everything in the equation now. (5x + 6x), (-2y + 2y), and (12 + 32).

11x = 44

To get x alone, Divide each side by 11. Then we will get the value of x.

11/11x = 44/11

x = 4

Horray! We got x, but what about y? Pick one of the equations. I will go with 5x - 2y = 12. Substitute the x value inside the equation.

5(4) - 2y = 12

20 - 2y = 12

-2y = -8

y = 4

Good! We figured out y. Now we know the solution! The solution is (4,4).

Technology Method:

Grab a graphing calculator. Enter the equations. You will see two lines. Look at where they intersect. The point where they intersect is the solution. That line is (4,4). You could also do this on a piece of paper by graphing the equations.

I hope this helps! Let me know if you need any more help or if I got anything wrong.

Answer:

[tex]f(x) = x^{2} - 1[/tex]

Step-by-step explanation:

The definition of even function is: [tex]f(x) = f(-x)[/tex]

I am going to assume the  second option is [tex]f(x) = x^{2} - 1[/tex] and the answer.

[tex]f(x) = x^{2} - 1\\f(-x) = (-x)^{2} - 1 = x^{2}-1[/tex]

Answer:

The instantaneous rate of change of [tex]y[/tex] with respect to [tex]x[/tex] at the value [tex]x = 3[/tex] is 18.

Step-by-step explanation:

a) Geometrically speaking, the average rate of change of [tex]y[/tex] with respect to [tex]x[/tex] over the interval by definition of secant line:

[tex]r = \frac{y(b) -y(a)}{b-a}[/tex] (1)

Where:

[tex]a[/tex], [tex]b[/tex] - Lower and upper bounds of the interval.

[tex]y(a)[/tex], [tex]y(b)[/tex] - Function exaluated at lower and upper bounds of the interval.

If we know that [tex]y = 3\cdot x^{2}[/tex], [tex]a = 3[/tex] and [tex]b = 6[/tex], then the average rate of change of [tex]y[/tex] with respect to [tex]x[/tex] over the interval is:

[tex]r = \frac{3\cdot (6)^{2}-3\cdot (3)^{2}}{6-3}[/tex]

[tex]r = 27[/tex]

The average rate of change of [tex]y[/tex] with respect to [tex]x[/tex] over the interval [tex][3,6][/tex] is 27.

b) The instantaneous rate of change can be determined by the following definition:

[tex]y' = \lim_{h \to 0}\frac{y(x+h)-y(x)}{h}[/tex] (2)

Where:

[tex]h[/tex] - Change rate.

[tex]y(x)[/tex], [tex]y(x+h)[/tex] - Function evaluated at [tex]x[/tex] and [tex]x+h[/tex].

If we know that [tex]x = 3[/tex] and [tex]y = 3\cdot x^{2}[/tex], then the instantaneous rate of change of [tex]y[/tex] with respect to [tex]x[/tex] is:

[tex]y' = \lim_{h \to 0} \frac{3\cdot (x+h)^{2}-3\cdot x^{2}}{h}[/tex]

[tex]y' = 3\cdot \lim_{h \to 0} \frac{(x+h)^{2}-x^{2}}{h}[/tex]

[tex]y' = 3\cdot \lim_{h \to 0} \frac{2\cdot h\cdot x +h^{2}}{h}[/tex]

[tex]y' = 6\cdot \lim_{h \to 0} x +3\cdot \lim_{h \to 0} h[/tex]

[tex]y' = 6\cdot x[/tex]

[tex]y' = 6\cdot (3)[/tex]

[tex]y' = 18[/tex]

The instantaneous rate of change of [tex]y[/tex] with respect to [tex]x[/tex] at the value [tex]x = 3[/tex] is 18.

Answer: 0.796 meters

Step-by-step explanation:

Circumference of circle = [tex]2\pi r[/tex] , where r=radius

Here, Circumference of loop = 2.5 meters

i.e. [tex]2\pi r=2.5[/tex]

[tex]\Rightarrow\ r=\dfrac{2.5}{2\pi}[/tex]

[tex]\Rightarrow\ r=\dfrac{2.5}{2\times\dfrac{22}{7}}\\\\\Rightarrow\ r=\dfrac{2.5\times7}{2\times22}\\\\\Righttarrow\ r=0.398\ m[/tex]

Diameter = 2r = 2(0.398) = 0.796 meters

Hence, The diameter of Taiga's exercise hoop = 0.796 meters

Answer:

Kindly check explanation

Step-by-step explanation:

Organizations like NASA who explore space and planets often have to deal with measurement of very long distances such as the one stated above. The Major challenge with the distance written in the format expressed above is the difficulty to read, state or use in mathematical calculations as it is too explicit. A more effective method is to express this distance in standard format and more suitable long distant units such as miles.

For instance;

880,000,000,000,000,000,000,000 kilometers could be expressed as in standard form as ;

The angle A using the sum of the angles in a right-angle triangle formula,

is = 44.5°

According to the definition of a right triangle, if one of the triangle's angles is a right angle (90 degrees), the triangle is referred to as a right-angled triangle or just a right triangle.

A right triangle's initial characteristic is that one of its angles is 90 degrees. The biggest angle in a right triangle, the 90° angle is a right angle. The other two angles are either sharp or less than 90 degrees.

Now in the given question,

AB = 7

AC = 5

∠C = 90°

Using the formula Sin ∠B = 5/7

Simplifying it:

(Sin ∠B) = 5/7

⇒ [tex]Sin^{-1}[/tex] (Sin∠A) = [tex]Sin^{-1}[/tex] 5/7

⇒ ∠B ≈ 45.5°

Now we know ∠A + ∠B + ∠C = 180°

⇒ ∠A = 180° - 90° -45.5°

⇒ ∠A = 44.5°

Therefore, angle A in the triangle = 44.5°

Answer:

56.25 pound of the coffee that costs $5 per pound is needed

18.75 pound of the coffee that costs $9 per pound is needed

Step-by-step explanation:

Let the number of pounds be x and y respectively

The total pounds is 75;

So;

x + y. = 75 •••••••(i)

Total cost of first type

9 * x = $9x

Total cost of second type;

5 * y= $5y

75 pound at $6 per pound; total cost of this is;

6 * 75 = $450

Thus;

9x + 5y = 450 ••••••••(ii)

From i, x = 75-y

Put this into ii

9(75-y) + 5y = 450

675 -9y + 5y = 450

4y = 675-450

4y = 225

y = 225/4

y = 56.25

x = 75 - y from i

x = 75-56.25

x = $18.75
