Answer 1

Answer:

area = 18.81 m²

Step-by-step explanation:

solving for the 7 sided polygon first:

divide into 7 equal isosceles triangles, each having sides of 10 m and a peak angle of 360°/7 = 51.43°. Drop a line from the peak & perpendicular to the base makes a right triangle with a 25.71° peak angle and a 10 m hypotenuse.

sin 25.71° = x/10, x = 4.34, the base of the full triangle will be 2 x 4.34 = 8.68 m

cos 25.71° = x/10, x = 9.01, the rise of the triangle is 9.01 m

The area of each triangle will be 1/2(8.68)(9.01) = 39.10 m²

39.10 x 7 triangles = 273.72 m²

area of 7 sided polygon = 273.72 m²

Next solve for the inner circle:

The rise of the triangle (9.01) is the radius of the inner circle.

area of inner circle = πr² = 3.14(9.01²) = 254.91 m²

273.72 - 254.91 = 18.81 m²

What is the value of A when we rewrite 3^x as A^5x

Answers

Answer:

A=3^1/5

Step-by-step explanation:

3^x = 3 ^ 1/5*3^5x. Basically you need 3^x to equal A^x. A^x is equal to A^5x in this situration. So, multiply 5x to equal 1x. To make 1x you need to multiply the 5x by 1/5. So, the A value is 3, since the whole number in the 3^x has to be equal to the whole number in A^x. Knowing this, we can tell that A must be equal to 3^1/5.

Answer:

The answers to both the subparts of the equations are shown:

(A) Re-written equation by completing the square: (x-7)² - 5 = 0(B) Solutions of the equation: x = 12, x = 2

What are equations?Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the two equations 3x + 5 and 14, which are separated by the 'equal' sign, make up the equation 3x + 5 = 14.

So, the equation is:

−34 = x² −14x+10

(A) Rewrite the equation by completing the square:

−34 = x² −14x+10x² - 14x + 44 = 0(x² - 14x + 49) - 5 = 0(x-7)² - 5 = 0

(B) The solutions of the equation:

(x-7)² = 5x-7 = 5x-7 = -5x= 12, x=2

Therefore, the answers to both the subparts of the equations are shown:

(A) Re-written equation by completing the square: (x-7)² - 5 = 0(B) Solutions of the equation: x = 12, x = 2

2. Simplify.

apply the Distributive Property. 2(5y-3)+2(4y)=10y-6+8ycombine like terms. 10y-6+8y=18y-6

3. Therefore, 18y-6=174.

The areas of two squares
in the model are given.
Find the area of the
third square.
625 units2
400
units2

Answers

Answer:

225 u²

Step-by-step explanation:

The area of the larger square is 625 u². We know that area of square is the square of side. So ,

⇒ a² = 625 u²

⇒ a = √625 u²

a = 25 u .

Similarly finding the side of second square as ,

⇒ a'² = 400 u²

⇒ a' = √400 u²

a' = 20 u

If we see these are the hypontenuse and base of a right a Angled triangle formed between the square. The measure of perpendicular will be the side lenght of third square.

⇒ h² = p² + b²

⇒( 25u)² = p² + (20u)²

⇒ p² = 625 - 400 u²

⇒ p² = 225 u²

This p² is only the area of square .

Hence the area of third square is 225 u² with a side lenght of 15 u .

225 units
