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).
It’s 8/15 decimal form it’ll be 0.53 hope this helped !
(8/9)^2 is just 8/9 squared, or 8/9 * 8/9. This is 64/81, and cannot be reduced. This is therefore our answer.
Answer:
45ft squared
Step-by-step explanation:
you multiply 3 by the radius which is 15
that gives you a total of 45
Answer:
120
Step-by-step explanation:
volume of triangular prism = area of base times length
the base is a triangle and the area of a triangle can be calculated by using this formula
where b = base length and h = height
Dimensions of base
base length = 8cm and height = 3cm
Thus,
The length of the triangular prism is 10cm
Thus volume = 10 * 12 = 120
