Answer:
a) -64
0
b) 5
- 5
Step-by-step explanation:
Up square: Multiply the numbers in the right square and left square and write the answer in the up square.
Down square: Add the numbers in the right square and left square and write the answer in the down square.
Left and right square: Factorize the number in the up square and check if it satisfies (add or subtract the factors) the number in the down square.
a) Up square: -64
8*(-8) = -64
Down square: 0
8 + (-8) = 0
b) Factorize (-25), in such a way that when we add we should get 0.
-25 = 5 * (-5)
5 + (-5) = 0
Right square: 5
Left square : -5
c) Right square: (-3)
-12 ÷ 4 = (-3)
Down square : 1
4 + (-3) = 1
Answer:
24

Answer:
c
Step-by-step explanation:
The area of a circle is represented by the equation:
We know that the diameter is two times the radius:
So if we know that the diameter of the circle is 24m, we can divide this by two in order to get the radius:
-->
So then we can plug this radius in to the equation for the area of a circle:
We are told to use 3.14 as pi, and not pi itself, so let's plug in 3.14 for pi:
Now we know that the area of this circle is 452.16 square meters.
Answer:
1
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.
Trigonometric functions are used to show the relationship between the angles of a triangles and the sides of the triangle. For a right angled triangle, the ratio of the sides can be gotten using trigonometric functions such as:
cosθ = adjacent/hypotenuse, sinθ = opposite/hypotenuse, tanθ = opposite/adjacent
Given the right angle triangle:
cos(A) = adjacent / hypotenuse = 3 / 4.24
cos(A) = 3 / 4.25
cos(B) = adjacent / hypotenuse = 3 / 4.24
cos(B) = 3 / 4.24
cos(A) / cos(B) = (3 / 4.24) ÷ (3 / 4.24) = 1
cos(A) / cos(B) = 1
