What class is this for? I’ll help you but i don’t see a picture or anything. How many dogs were bought around the world or in one particular area?
Answer:
8
Step-by-step explanation:
Area = 1/2bh
200 = 1/2(50)h
200=25h
8=h
The axis of symmetry of h(x) = 5x2 + 40x + 64 = -4
The formula for calculating the axis of symmetry is expressed as:
Axis of symmetry x = -b/2a
h(x) = 5x^2 + 40x + 64
a = 5 and b = 40
Answer: A
Step-by-step explanation:
Looking at the conditions, we can eliminate D. An isosceles triangle has 2 equal sides. 2 cm, 3 cm, 4 cm don't have 2 equal lengths.
We can next eliminate C. C is a right scalene triangle. Even if this is a scalene triangle, the key is the work "right". Any right triangle, regardless of it's angles, always fit the Pythagorean Theorem. C does not fit the Pythagorean Theorem.
2²+3²=4²
4+9=16
13≠16
We are left with the options A and B. A and B can both be correct answers, but it is the condition given in the problem that makes A the right answer. A states acute scalene triangle. That means there is at least 1 acute angle. Technically, B is also correct, but because the problem explicitly states 29°, that makes A the correct answer.
Answer: line: To represent straight objects in geometry, mathematicians introduced the concept of line or straight line
rays: vector, a ray is a vector from a point to a point. In geometry, a ray is usually taken as a half-infinite line (also known as a half-line) with one of the two points and taken to be at infinity
segments: The term line segment refers to a section of a line bounded by two distinct points. It is comprised of all points on the line between its endpoints. A closed line segment includes both endpoints, whereas an open line segment excludes both endpoints.
