Answer:
Reflection over y-axis
Step-by-step explanation:
We know that with a reflection of the x-axis, we flip the value of the y value
But since the y-values in Q3 and Q4 are both negative, we know that can't be the case
So it has to be a reflection over the y-axis where the x-values are flipped
Hope this helps
It opens downwards so it looks like this “n”. That is because a in the formula is a negative number in this situation
Answer:
11
Step-by-step explanation:
Answer:
Simplest form = 4<em>z </em>+ 21
Case 1: True, Case II: false and Case III: true
Step-by-step explanation:
18<em>z </em>- 7( -3 + 2z)
= 18<em>z</em> + 21 - 14z
= 18<em>z</em> -14z + 21
= 4<em>z </em>+ 21
So, in the above expression we have two terms. First term is 4z and second term is 21.
So the first case is true. As the expression has two terms.
The coefficient of <em>z </em>is a number which is multiplied by <em>z</em>. Therefore, Second case is false as the coefficient of <em>z</em> is 4.
The constant is a number which is not multiplied by any variable. Therefore, third case is true as the constant number in above expression is 21.
Answer: 527.79 m²
Step-by-step explanation:
formula is A = 2πrh + 2πr²
A = 2π x 4 x 17 + 2π x 4²
A = 527.79 m²
