Write an addition equation or a subtraction equation (your choice!) to describe the diagram.

Answer:

x=41

Step-by-step explanation:

supplementary angles add to 180

3x + (2x-25) = 180

5x = 205

x= 41

 angle1          3x41 = 123

angle 2 (2x41) -25 = 57

 123 +57 = 180

[tex]\large{\boxed{\sf Chord = 8cm }}[/tex]

Step-by-step explanation:

First see figure in attachment . As we know that ,Perpendicular from centre of the circle bisects the chord . Hence here ,

[tex]\sf\qquad\longrightarrow AB = 2AC = 2x [/tex]

Now in ∆OAC , by Pythagoras Theorem , we have ;

[tex]\sf\qquad\longrightarrow (5cm)^2= x^2+(3cm)^2\\ [/tex]

[tex]\sf\qquad\longrightarrow 25cm^2=x^2+9cm^2\\[/tex]

Therefore , the length of chord will be ,

[tex]\sf\qquad\longrightarrow AB = 2x \\ [/tex]

[tex]\sf\qquad\longrightarrow AB = 2(4cm)\\[/tex]

[tex]\sf\qquad\longrightarrow \pink{ AB = 8cm } [/tex]

Explanation:

Use the distance formula to calculate the distance from R to S. This is identical to the length of segment RS.

[tex]R = (x_1,y_1) = (-3,-1) \text{ and } S = (x_2, y_2) = (0,3)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-3-0)^2 + (-1-3)^2}\\\\d = \sqrt{(-3)^2 + (-4)^2}\\\\d = \sqrt{9 + 16}\\\\d = \sqrt{25}\\\\d = 5\\\\[/tex]

Segment RS is exactly 5 units long.

-----------------------

Repeat similar steps to find the length of segment ST

[tex]S = (x_1,y_1) = (0,3) \text{ and } T = (x_2, y_2) = (3,0)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(0-3)^2 + (3-0)^2}\\\\d = \sqrt{(-3)^2 + (3)^2}\\\\d = \sqrt{9 + 9}\\\\d = \sqrt{18}\\\\d \approx 4.2426\\\\[/tex]

ST is roughly 4.2426 units long.

------------------------

Lastly, let's calculate the length of segment TR.

[tex]T = (x_1,y_1) = (3,0) \text{ and } R = (x_2, y_2) = (-3,-1)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-(-3))^2 + (0-(-1))^2}\\\\d = \sqrt{(3+3)^2 + (0+1)^2}\\\\d = \sqrt{(6)^2 + (1)^2}\\\\d = \sqrt{36 + 1}\\\\d = \sqrt{37}\\\\d \approx 6.0828\\\\[/tex]

TR is about 6.0828 units long.

------------------------

The factors of the polynomial equation by complete the statements about factoring by grouping are,

[tex](2x-1)\\(7x+3)[/tex]

The factor of a polynomial is the terms in linear form, which are, when multiplied together, give the original polynomial equation as a result.

To find the factor of a polynomial, make the groups of the equation, and equate them equal to zero.

The provided polynomial equation is,

[tex]14x^2+ 6x - 7x - 3[/tex]

Rearrange the equation,

[tex]14x^2- 7x + 6x - 3[/tex]

Take out the common terms 7x from the first two terms and 3 from the last two terms.

[tex]7x(2x- 1) + 3(2x - 1)\\(2x-1)(7x+3)[/tex]

Thus, the factors of the polynomial equation by complete the statements about factoring by grouping are,

The area of a plot is the amount of space on the plot

The area of the plot is 2x^2 -x - 1

The dimensions of the plot are given as:

Length=2x+1

Width=x-1.

The area of the plot is the product of its dimension.

So, we have:

[tex]Area = (2x + 1)(x - 1)[/tex]

Expand

[tex]Area = 2x^2 - 2x + x - 1[/tex]

Evaluate the like terms

[tex]Area = 2x^2 -x - 1[/tex]

Hence, the area of the plot is 2x^2 -x - 1

The annual rate of decay is r = 0.87

We know that if a quantity has a half-life of T, then the rate of decay must be such that:

r^T = 0.5

This means that when a time T passes, the original quantity becomes half of what it originally was.

In this case we know that the half-life is T = 5 years, then we have:

r^5 = 0.5

r = 0.5^(1/5) = 0.87

Then the annual rate of decay is r = 0.87, and if the initial quantity is 18 grams, we can write the exponential decay as:

f(t) = 18g*(0.87)^t

Answer:

-5

Step-by-step explanation:

x-intercepts occur when y = 0

⇒ 2x + 10 = 0

⇒ 2x = -10

⇒ x = -5

So the x intercept of 2x + 10 is (-5, 0)

Answer:

-5

Step-by-step explanation:

To find the x intercepts we must replace y with 0 and solve for X

So our equation is 0=2x+10

Now we must get x by itself by subtracting 10 on both sides. We subtract 10 because it is being added.

Well, instead of guessing we can solve :)

Divide 2 on both sides, this cancels out the two on the right and makes the -10 on the left turn into a -5.

Now we are left with x=-5

Thus, our answer is -5

Hope this helps!

Answer:

  x = 1 +√5

Step-by-step explanation:

There are different formulas for the area of a triangle available, depending on the given information.

When two sides and the angle between them are given, the relevant area formula is ...

  Area = 1/2(ab)sin(C)

When the base and height of a triangle are given, the relevant area formula is ...

  Area = 1/2bh

The problem statement tells us the two triangles shown have equal areas. That means the two formulas will give the same result.

  Area from angle = Area from base/height

  1/2(x·x)sin(30°) = 1/2(x-2)(x+1)

  x² = 2(x² -x -2) . . . . . . . . . . . use sin(30°) = 1/2, multiply by 4

  x² -2x -4 = 0 . . . . . . . . subtract x², eliminate parentheses

  (x -1)² = 5 . . . . . . . . . add 4+1 to complete the square

  x = 1 ± √5 . . . . . . take the square root, add 1

The value of x must be greater than 2 in order for the triangle side lengths to be positive. (x-2 > 0) This means x = 1-√5 is an extraneous solution.

The value of x is 1 +√5.

The given model would make the least sense to use for x=-2.75.

the given function is:

[tex]h(x)= -16x^2 +100[/tex]

a quadratic relationship,

where

h is the height in feet

x is the time in seconds

Kinetic energy is a form of energy that an object or a particle has by reason of its motion.

as we know that time always appears to run forward, never backward. cannot take negative values so option 1 i.e 2.75 is not possible. Also, after a certain period of time object will vanish all its kinetic energy, resulting in h=0 but h(-2.75)= -21 which is meaningless.

h(-2.75) = [tex]-16*(-2.75)^2+100 = -21\\[/tex]

h(0.25) = [tex]-16*0.25^2 +100=99[/tex][tex]-0.25^2*16+100=99[/tex]

h(1.75) = [tex]-16*1.75^2+100=51[/tex]

h(25) = [tex]-16*2.25^2+100= 19[/tex]

The largest possible area of the garden is 1666.67 square yards

Represent the length of the gardens with y, and the widths of the whole garden with x.

So, the perimeter of the garden is:

[tex]P = 3y + 2x[/tex]

The farmer has 200 yards.

So, we have:

[tex]3y + 2x= 200[/tex]

The area of the garden is:

[tex]Area = xy[/tex]

Divide the amount of fencing equally to maximize the area.

So, we have:

[tex]3y + 2x = 100 + 100[/tex]

This gives

[tex]3y = 100 \to y = \frac{100}3[/tex]

[tex]2x = 100 \to x = 50[/tex]

Recall that:

[tex]Area = xy[/tex]

So, we have:

[tex]Area = 50 * \frac{100}3[/tex]

Evaluate the product

[tex]Area = \frac{5000}3[/tex]

[tex]Area = 1666.67[/tex]

Hence, the largest possible area of the garden is 1666.67 square yards
