Step-by-step explanation:
1) -9 = 9 true/false
the answer is false because negative and positive quite unlike in terms.
2) -(-21) = -21
Using the symbols multiplication rule,
Where,
<h2>
+ × + = +</h2><h2>
- × - = +</h2><h2>
- × + = -</h2><h2>
+ × - = -</h2>
Therefore, -(-21) = +21 = 21
⟼ 21 = -21
the maximum height is the y-value of the vertex.
h(x) = -2x² + 20x + 48
<em> a=-2, b=20, c=48</em>
h(5) = -2(5)² + 20(5) + 48
= -50 + 100 + 48
= 50 + 48
= 98
Answer: 98 meters
Answer:
104 Pages
Step-by-step explanation:
on Monday she reads 3/8 of the novel which means
x 352 = 132 pages
on Tuesday she reads 28 pages, doesn't require any calculations.
on Wednesday she reads 1/4 of the novel,
x 352 = 88
Just add all of that,
132+28+88=248 Pages
Subtract the novel pages by the read pages value
352-248=104pages.
