Mathematics
1 answer:
Masteriza [31]3 years ago
7 0

Answer:

A) (Triangle) So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Example: Find the area of the triangle. The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

B) We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius.

C)The parallelogram area can be calculated, using its base and height.  

Area = ½ × d1 × d2 sin (y)

All Formulas to Calculate Area of a Parallelogram

Using Base and Height A = b × h

Using Trigonometry A = ab sin (x)

Using Diagonals A = ½ × d1 × d2 sin (y)

D)Area of a trapezoid is found with the formula, A=(a+b)/2 x h. Learn how to use the formula to find area of trapezoids.

Hope this helps!

All the love, Ya boi Fraser :)

8. Is the following statement true or false? Justify your conclusion. If a and b are nonnegative real numbers and a + b =0, then
atroni [7]

Answer:

If a + b = 0 then a = 0 and b =0

a  | b | a + b (answer)

0 | 0 | 0

0 | 1  | 1

0 | 2 | 2

1  | 0 | 1

2 | 0 | 2

1  | 1  | 2

2 | 1  | 3

 

Step-by-step explanation:

Considering the following conditions for the real numbers:

a\geq 0\\b\geq 0

Following the rules of these in-equations, it is possible to deduce:

a + b \geq 0

Then, if the proposed statement is:

a + b = 0

The conditions above shall comply the requirements established, but first, analyzing the statement:

If a \geq 0 and b \geq 0 then a + b \geq a, a + b \geq b and a + b \geq 0.

If a = 0 and b a non negative real number, then a + b \geq b, but because to a = 0, then a + b = b. Due to the commutative property of sums, the same behavior will be presented if b = 0 and a a non negative real number.

According to that, if  a + b = 0, then a = 0 and b = 0.

Solve the following inequality: -2y+6<10
Montano1993 [528]
-2y + 6 < 10

Subtract 6 on both sides

-2y < 10

Divide by -2 on both sides

y > -5

Hope this helps! Just in case you don’t understand the final answer, when dividing or multiplying by a negative number you flip the sign!
