Answer:
64 m, at time t = 4 sec
Step-by-step explanation:
We must maximize the function h = 32t – 4t^2. One way in which to do this is to find the axis of symmetry, t = -b / [2a], and from that calculate the height:
a = -4, b = 32, c = 0
-32
and therefore the axis of symmetry is t = ---------------- = 4
2(-4)
The height, h, at time t = 4, is h(4) = 32(4) - 4(4)^2 = 64 m
The maximum height of the ball is 64 m, at time t = 4 sec
Step-by-step explanation:
The golf ball reaches its maximum vertical height when its vertical velocity h' becomes zero. Taking the derivative of h and setting it to zero, we get
h' = 32 - 8t = 0
which gives us t = 4 seconds. So after 4 seconds, the ball will reach its maximum height and its value is
h = 32(4) - 4(4)^2
= 128 - 64
= 64

Gió thổi trên mặt nước trong các đại dương chịu trách nhiệm cho dòng hải lưu. Tuy nhiên, dòng hải lưu trong đại dương không được hình thành bởi gió đơn thuần. Nước gần cực lạnh trong khi nước gần xích đạo ấm. Sự chênh lệch nhiệt độ giữa hai vùng nước này cũng chịu trách nhiệm cho sự hình thành dòng hải lưu. Địa hình đáy đại dương, mưa và thậm chí thủy triều cũng gây ra dòng chảy trong nước.

How are prisms and pyramids alike and how are they different?
Prisms and pyramids are geometric shapes that have flat sides, flat bases and angles. So those are some similarities. However, the bases and side faces on prisms and pyramids differ. Prisms have two bases while pyramids only have one. There are a variety of pyramids and prisms, so not all shapes in each category look the same.

Is x=2 a root of (2x-3)(3x + 2)(x+2)(x+2)(x-7/8)?
Answer:
No
Step-by-step explanation:
2x-3 = 0 so x = 3/2
3x+2 = 0 so x = - 2/3
x+2 = 0 so x=-2 (twice)
x-7/8 = 0 so x=7

Doug needs to order 25,000 g of a
supplement. At the store,
supplements come in 5 kg packages
that cost $80 each. What will Doug's
order cost?
Answer:
$2000
Step-by-step explanation:
1,000 g would be = 1 Kg so it would be 25 Kg
And 25 X 80 = 2000
Answer:
$400
Step-by-step explanation:
25,000 grams is equal to 25 kg, so if 5 kg equals $80, the total 25 kg divided by 5 equals five. With this you multiply; 5 × 80 kg = 400. So $400 is the answer.

Step-by-step explanation:
Use the trig ratio tan to find b
4.5 x tan (23) = b = 7.14668887526
7.1
Answer:
b ≈ 1.9
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{b}{4.5}[/tex] ( multiply both sides by 4.5 )
4.5 × tan23° = b , then
b ≈ 1.9 ( to the nearest tenth )
There are
15
apples in a basket.
6
of these apples are green. The rest of them are red.
(a) What is the ratio of red apples to all apples in the basket?
(b) What is the ratio of green apple to red apples?
Answer:
(a) 9:15
(b) 6:9
Step-by-step explanation:
Total apples: 15
6 : green
9 are red
9:15
6:9
Answer:
(a) 3 : 5
(b) 2 : 3
Step-by-step explanation:
green apples = 6 total apples = 15 red apples = 15 - 6= 9 apples
(a) red apples : all apples= 9 : 15
for simplified form dividing numerator and denominator by 3
= 3 : 5
(b) green apples : red apples= 6 : 9
for simplified form dividing numerator and denominator by 3
= 2 : 3

Nelda baked two kinds of pasta in pans. Each pan was the same size. She sliced one pan of pasta into 4 equal pieces. She sliced the other pan into 6 equal pieces. How can the pans of pasta now be sliced so that both pans have the same-sized pieces? If Nelda has served 8 pieces from 1 pan so far, what fraction of 1 pan has she served?
Answer:
6 equal parts; 8 equal parts
Both those will go into 24.
Step-by-step explanation: Each of six slices of the first pasta has the area 1%2F6 of the entire pan.
Each of eight slices of the second pasta has the area 1%2F8 of the original pan.
Nelda will cut each 1%2F6 in 4 equal pieces to get 1%2F24.
She also will cut each 1%2F8 in 3 equal pieces to get 1%2F24.
solve the equation by completing the square. Round to the nearest hundredth if necessary.
