Answer:
Step-by-step explanation:
A quadratic function has the formula ax² + bx + c
- To determine if a graph will be narrow or wide, the leading coefficient, a, will be the factor that determines this
- The greater the coefficient, the narrower the parabola
- The lesser the coefficient, the wider the parabola
Here all of the functions are in the form ax²
- In
, our "a" term is 
- In y = -2x², our "a" term is -2
- In y = -3x², our "a" term is -3
- In
, our "a" term is 
We can eliminate the two functions with the negative coefficients because they are much smaller than the two functions with the fractions as coefficients, and will therefore open much wider.
We can now compare the two remaining functions, and 
- Giving the two fractions common denominators would turn them into
and 
- The equation with the larger fraction will be the parabola that is the narrowest. In this case, it is the .
- Therefore, will have the narrowest graph
Answer: Choice B) 3/5
==================================================
Explanation:
The smaller horizontal side is JM = 15
The larger horizontal side is NQ = 25
The ratio of these corresponding sides is:
small/large = 15/25 = (5*3)/(5*5) = 3/5
----------------
Alternatively,
The smaller vertical side is ML = 18
The larger vertical side is QP = 30
The ratio of these corresponding sides is:
small/large = 18/30 = (6*3)/(6*5) = 3/5
----------------
Either way, the answer is 3/5
Answer:
The expression equivalent to 8 - (6r + 2) is -6r + 6 ⇒ A
Step-by-step explanation:
Let us solve the question
∵ The expression is 8 - (6r + 2)
→ Multiply the bracket by (-)
∵ (-) × (+) = (-)
∴ 8 - (6r + 2) = 8 - 6r - 2
→ Add the like terms
∵ 8 - (6r + 2) = (8 - 2) - 6r
∴ 8 - (6r + 2) = 6 - 6r
→ Switch the terms
∴ 8 - (6r + 2) = -6r + 6
∴ The expression equivalent to 8 - (6r + 2) is -6r + 6
Answer:
im gonna guess d?
Step-by-step explanation:
cuz it goes up
So that when you add divide or multiply the three sides you get your complete answer length times width times height.
