Answer:
1A. acute. all of the angles are under 90%. acute is under 90%, right is 90%, and obtuse is over 90%
2A. scalene. isosceles is all sides are the same length, and equilateral is all sides are the same length AND all the angles are 60%. with scalene all sides can be different lengths, and angles can be different
3. no. the rule for making a triangle is that any 2 sides added up, must be more than the 3rd side. so 6+2, 6+4 work, but 2+4 is 6, which is not greater than 6, the third side

Find the area of the object
Answers
Answer:
2π + 24 m² = 30.3 m²(3 s.f.)
Step-by-step explanation:
Area of rectangle: l x w
6 x 4 = 24 m²
Area of semicircle: πr²/2
r = 4/2 = 2
π x 2² / 2
4π / 2
2π
Total area: 2π + 24 m² = 30.3 (3 s.f.)

Use a graphical method to find estimates for the solutions of the simultaneous equations x^2 + y^2=2.25 y-x=1
NEED ASAP WILL MARK AS BRAINLIEST
Answers
Answer:
A) which graph represents the equation x^2 + y^2 = 2.25?
First, the general equation for a circle can be written as:
(x - a)^2 + (y - b)^2 = R^2
This is a circle of radius R centered in the point (a, b).
Then we can rewrite our equation as:
(x - 0)^2 + (y - 0)^2 = (√2.25)^2 = (1.5)^2
Then we have a circle centered at the point (0, 0) and with a radius equal to 1.5
Then we can see that the correct one is graph C.
b) Now we want to solve the system:
x^2 + y^2 = 2.25
y - x = 1
graphically.
To do it we need to graph both equations and see in which points do they intersect.
We already have the first equation graphed, so we only need to also graph the linear equation:
y - x = 1
y = 1 + x
An example of this can be seen in the graph below:
There we can estimate one of the intersections as (0.4, 1.4) and the other as (-1.4, -0.4)

The graph of line p represents = x-1. If the slope of line p is multiplied by (-10)
to create liner, which statement about the graphs of the two lines is true?
A
Line r intersects line p.
B Line ris parallel to line 2.
CLine ris 10 units above line p.
D
Line ris 10 units below line p.
Answers
Answer:
A. Line r intersects line p
Step-by-step explanation:
to find the second graph multiply the slope of line p by -10
slope is 1/5 or 0.2
So,
0.2 * -10 = -2
slope of second line is -2
Graph shown
Altered line shown in blue
Line p shown in green

Find the average rate of change of g(x) =-x²+2x+2 from x=2 to x = 6.
Simplify your answer as much as possible.
Answers
Solve the equation replacing x with 2 and the 6:
-2^2 + 2(2) + 2 = 4 + 4 + 2 =10
-6^2 + 2(6) + 2 = 36 + 12 + 2 = 50
Difference between the answers: 50-10 = 40
Difference between 2 and 6 = 6-2 = 4
Average rate of change = 40/4 = 10
