Answer:

acute triangle

Step-by-step explanation:

For an acute, the angles should be less than 90°

right should be equal to 90°

obtuse, angles should be less than 180 but greater than 90

Answer:

3. acute

Step-by-step explanation:

The triangle is an acute angle as all its measures are less than (<) 90°.

89° < 90°

78° < 90°

13° < 90°

=》Triangle → c. acute

1. 5/6 = 10/12

  3/4 = 6/8

2. 2/9 = 4/18

   4/12 = 1/3

3. 6/7 = 12/14

   1/2 = 2/4

4. 5/9 = 10/18

   3/18 = 1/6

5. 1/6 = 2/12

   1/9 = 2/18

6. 3/8 = 6/12

   5/6 = 10/12

What are the solutions for x when y is equal to 0 in the following quadratic
Scrat [10]

Answer: Option C

Step-by-step explanation:

Given the quadratic equation y = x^2 - 13x, substitute y=0:

 0 = x^2 - 13x

In this case, to find the solutions of the given quadratic equation, you must factor out the variable "x". Then:

0=x(x-13)

Therefore, you get that the solutions of this equation are the following:

x=0\\\\\\x-13=0\\x=13

Then, the answer is:

x = 0\ or\ x = 13

This matches with the option C.

The function h(x) = x2 + 14x + 41 represents a parabola.
defon
Part A:

h(x)= x^{2} +14x+41

The first step of completing the square is writing the expression x^{2} +14x as (x+7)^{2} which expands to x^{2} +14x+49.

We have the first two terms exactly the same with the function we start with: x^{2} and 14x but we need to add/subtract from the last term, 49, to obtain 41. 

So the second step is to subtract -8 from the expression x^{2} +14x+49

The function in completing the square form is
h(x)= (x+7)^{2}-8

Part B:

The vertex is obtained by equating the expression in the bracket from part A to zero

x+7=0
x=-7

It means the curve has a turning point at x = -7

This vertex is a minimum since the function will make a U-shape. 
A quadratic function a x^{2} +bx+c can either make U-shape or ∩-shape depends on the value of the constant a that goes with x^{2}. When a is (+), the curve is U-shape. When a (-), the curve is ∩-shape

Part C:

The symmetry line of the curve will pass through the vertex, hence the symmetry line is x=-7

This function is shown in the diagram below
