Answer:
the rocket will reach its maximum height after 4 seconds.
Step-by-step explanation:
The first term ( -4.9(t-4)^2 ) can never be positive, so the maximum height of 80 meters is achieved when t = 4.
Answer:
y = 1
Step-by-step explanation:
no slope, and Y will always equal 1
Answer:
Step-by-step explanation:
Let a , b , c & d be the no. of chairs in hall A , B , C & D respectively.
Given,
b = 4a
c = a + 15
d = a + 8 + 4a = 5a + 8
Now,
Total no. of chairs (T) = a + b + c + d
= a + 4a + a + 15 + 5a + 8
= 11a + 23
Now,
Average chairs in each hall (Avg) = T/4
= (11a + 23)/4
3/4(8p+12)+3/8(16p-8)
=3/4[(8p+12)+1/2(16p-8)]
=3/4[8p+12+8p-4]
=3/4[16p+8]
=3/4*8*[2p+1]
=6[2p+1]
=12p+6
Answer:
<u>It should be 128 inches or 10.67 feet tall</u>
Step-by-step explanation:
Real size of the monument = 160 feet tall
Scale used by Tonya = 4 inches equal to 5 feet
Scale model of the monument = Real size of the monument / Scale used
Proportion between real monument and scale model = 160 / 5 = 32
It means that the proportion between the real monument and the scale model is 32
Scale model height = Proportion * scale used
Scale model height = 32 * 4
<u>Scale model height = 128 inches</u>
<u>Scale model height = 128/12 = 10.67 feet (12 inches = 1 feet)</u>
