-3^2 + (2-6)(10
9 + (-4)(10)
9 + (-40)
9 - 40
-31
Hope this is correct and that it helps :)
A linear function represents a line, a quadratic function represents a parabola.
The dots fit a parabolic behaviour (they are descendent at the beginning, they reach a minimum and then start growing again), so a quadratic model could fit the dots much better than a linear one.
Answer:
Is it a multiple choice question
Step-by-step explanation:
25% of 42=25 divided by 100 x 42
25\100 x 42=10.5
Answer:
This is an acute triangle
Step-by-step explanation:
Pythagoras theorem is used to determine if a triangle is right, acute or obtuse
If the sum of squares of two shorter lengths is greater than the square of third side then the triangle is an acute triangle.
If the sum of squares of two shorter lengths is less than the square of third side then the triangle is an obtuse triangle.
If the sum of squares of two shorter lengths is equal the square of third side then the triangle is a right triangle.
so,
As 1600<1945, the given triangle is an acute triangle ..
