Answer: Because the a-value is negative.
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: y = a(x - h)² + k where
- "a" is the vertical stretch
- -a is a reflection over the x-axis
- h is the horizontal shift (positive = right, negative = left)
- k is the vertical shift (positive = up, negative = down)
Given: g(x) = - (x + 1)² - 3
↓
a= -1
Since the a-value is negative, the parabola will be reflected over the x-axis which will change the curve from (U-shaped) to (∩-shaped).
Answer:
he have left 4.45 kg
Step-by-step explanation:
The computation of he have left is as follows:
= Total salt purchase - salt used on his sidewalk - sales used on the driveway
= 4.45 kg
Hence, he have left 4.45 kg
First you multiply 145 by 01.75 to get how much you add to the total. You add 253.75 to 145 and get 398.75 as the answer
It looks like a slide because it looks to be shifted not flipped or changed in other way.
Mean is the sum of the numbers divided by the number of number
41.42
The median is the middle number, in this case you add the two middle numbers and divide it by 2
61.615
the mode is the number that occurs the most
there is no mode
