If the tree is 25 feet tall , what is the angle of depression to his friend

Answer:

The answer is C.

Step-by-step explanation:

In order to find the value of expression, you first have to solve x by substracting 6 to both sides then divide it by 5 :

[tex]5x + 6 = 10[/tex]

[tex]5x + 6 - 6 = 10 - 6[/tex]

[tex]5x = 4[/tex]

[tex]5x \div 5 = 4 \div 5[/tex]

[tex]x = \frac{4}{5} [/tex]

Next, you have to substitute the value of x into the expression :

[tex]let \: x = \frac{4}{5} [/tex]

[tex]10x + 3[/tex]

[tex] = 10( \frac{4}{5} ) + 3[/tex]

[tex] = 8 + 3[/tex]

[tex] = 11[/tex]

Answer:

The vertex form of a quadratic is given by

y = a(x – h)^2 + k, where (h, k) is the vertex. h may act as "x" in this case.

Step-by-step explanation:

The vertex form of a quadratic is given by

y = a(x – h)^2 + k, where (h, k) is the vertex.

You must simply get an equation in this format to find h and k.

The x value of the vertex in a parabola is found using the formula -b/(2a), which represents the x-coordinate of the vertex, a critical point that determines the parabola's maximum or minimum value.

The x value of the vertex in a parabola is a critical point that determines the maximum or minimum of the quadratic function. In a quadratic equation of the form f(x) = ax^2 + bx + c, the x-coordinate of the vertex can be found using the formula -b/(2a). This formula is derived from completing the square or using calculus to find the critical points of the function. Once you determine the x-coordinate of the vertex, you can substitute it back into the original equation to find the corresponding y-coordinate, giving you the full coordinates of the vertex of the parabola.

The Step 2 shows the mistake done by Ettiene.

A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0. with a ≠ 0 .

It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem.

Given:

The given equation is x(x+4)=117.

Step1:  x²+4x=117

Now, b/2 =4/2 =2

Then, add 2² to both the sides of an equation, we get

x²+4x+2²=117+2²

x²+4x+4=117+4

(x+2)²=121

x+2=±√121

x+2=±11

x=±11-2

x=11-2=9 and x=-11-2=-13

The events that are mutually exclusive are Landing on a shaded sector and landing on the number three and Landing on an unshaded sector and landing on a number less than 2.

Mutually exclusive means that a combination of occurrences can never occur.

a) landing on a number greater than three while in a shaded area:

This is possible; for example, you could land in the 4.

b) landing in an even number on a dark sector.

Again, sector 4 is an even number and a shaded sector, thus these events do not conflict.

c) uncolored and odd number

This event is not mutually exclusive because you can land in the 3, which is unshaded and an odd number.

d) Landing on a shaded sector and landing on the number three

Because 3 is an unshaded sector, you can never land in 3 and a shaded sector at the same time; the two are mutually exclusive.

e) Landing on an unshaded sector with a number less than two.

Because 1 is the only integer smaller than 2, and sector 1 is darkened, these events are mutually exclusive.

Step-by-step explanation:Trust me

4x-7=9

4x-7+7=9+7

4x=16

4x/4 = 16/4

X=4

Answer: x = 4

Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is 4x.

To isolate 4x, we have to get rid of the -7 by adding

7 to both sides of the equation.

That leaves us with 4x = 16.

Now divide both sides by 4 to find that x = 4.

Answer:

41.9 units³

Step-by-step explanation:

(please see attached for reference)

The volume of a cone is given by:

V = (1/3) πr²h    where,

V = volume (we are asked to find this)

π = 3.142

r = radius = given as 2

h = height = given as 10

Substituting the known values into the above equation,

V = (1/3) πr²h

= (1/3) (3.142) (2²)(10)

= 41.893

= 41.9 units³  (nearest tenth)

Answer:

The ratio of the volume of cone to square pyramid is π or 3.14

Step-by-step explanation:

Given

Shapes: Cone and Square Pyramid

Diameter of the cone, d = 10 inches

Height of the cone, h = 12 inches

Height of the pyramid, h = 12 inches

Base edge of the pyramid, a = 5 inches

Required:

Ratio of the volume of cone to square pyramid.

First, we calculate the volume of each shapes

Volume of a cone is calculated as follows;

Volume = ⅓πr²h

Where r = radius = ½d

Recall that d = 10 inches

So, r = ½ * 10 inches

r = 5 inches.

Hence,

Volume = ⅓ * π * 5² * 12

Volume = ⅓ * π * 25 * 12

Volunteer = π * 25 * 4

Volume = 100π in³

Calculating Volume of the pyramid.

Volume = ⅓a²h

Recall that a = 5 and h = 12

So, Volume = ⅓ * 5² * 12

Volume = ⅓ * 25 * 12

Volume = 25 * 4

Volume = 100 in³

Now that both volumes have been calculated.

The ratio of the volume of cone to square pyramid is calculated by dividing the volume of the cone by the volume of the square pyramid.

Ratio = 100π ÷ 100

Ratio = π

Taking π as 3.14

Ratio = 3.14

Hence, the ratio of the volume of cone to square pyramid is π or 3.14

18.84x3=56.52

The area of the given polygon is 11.7 cm².

Given is an equilateral triangle with radius of 3 cm, we need to find the area of the polygon,

The radius of a circumcircle of an equilateral triangle is equal to a/√3, where a is the side length of the equilateral triangle.

So,
a/√3 = 3

a = 3√3

Now the side length is 3√3 cm.

Now, the area of an equilateral triangle is:

A = √3 / 4 × side²

= √3 / 4 × (3√3)²

= √3 / 4 × 27

= 11.7 cm²

Hence the area of the given polygon is 11.7 cm².

Answer:

B) Subtract the bottom equation from the top equation.

C) Add the equations.

Step-by-step explanation:

Let us analyze each of the options to see which one of them work.

A) Multiply the top equation by 7, then subtract the bottom equation from the top equation.

Multiplying the top equation by 7 gives:

7 * (16x + 5y) = (1 * 7)

112x + 35y = 7

Then, subtracting the bottom equation from this:

 112x + 35y = 7

-  (16x - 5y = 7)

=> 112x + 35y - 16x + 5y = 7 - 7

112x - 16x + 35y + 5y = 0

96x + 40y = 0

This method didn't eliminate any variable, so it didn't work for us.

B) Subtract the bottom equation from the top equation

This will yield:

  16x + 5y = 1

- (16x - 5y = 7)

=> 16x + 5y - 16x + 5y = 1 - 7

16x - 16x + 5y + 5y = -6

0x + 10y = -6

10y = -6

y = -6 / 10

Hence, one variable has been eliminated. It works.

C) Add the equations

This yields:

  16x + 5y = 1

+ 16x - 5y = 7

  32x + 0y = 8

  32x = 8

=>x = 8 / 32 = 1 / 4

This method works since one variable has been eliminated.

(Option C: (3 + i)/2 and (3 - i)/2

The solutions to the quadratic equation 2x^2 - 6x + 5 = 0 are 1.5 + 0.5i and 1.5 - 0.5i, as the discriminant is negative and indicates there are no real solutions, only complex ones.

Explanation:

The solutions of the quadratic equation 2x2 - 6x + 5 = 0 can be calculated using the quadratic formula, which is:

x = (-b ± √(b2 - 4ac)) / (2a)

For the given equation, a = 2, b = -6, and c = 5. Plugging these values into the quadratic formula, we get:

x = (6 ± √((-6)2 - 4(2)(5))) / (2(2))
x = (6 ± √(36 - 40)) / 4
x = (6 ± √(-4)) / 4

Since the discriminant (b2 - 4ac) is negative, this equation has no real solutions and two complex solutions. The final solutions are:

x = (6 ± 2i) / 4

x = (3 ± i)/ 2
x = 1.5 ± 0.5i

The solutions are 1.5 + 0.5i and 1.5 - 0.5i.

The equation is 4x + 9 = 45 which is the correct answer would be option (C).

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, separated by an equal sign (=). The left side and the right side of the equation can contain variables, constants, and mathematical operations.

Option A: 9x - 7 is not an equation because it does not have an equal sign.

Option B: (b + 7) x 3 is not an equation because it does not have an equal sign.

Option C: 4x + 9 = 45 is an equation because it has an equal sign and shows that the left side and the right side are equal.

Option D: (⅔)x - 3 > c is not an equation because it does not have an equal sign. Instead, it is an inequality, which shows that one expression is greater than or less than another expression.

Hence, the correct answer would be an option (C).
