The height of an object thrown upward with an initial velocity of 32 feet per second is given by the formula h = −16t2 + 32t, wh
andre [41]

Answer:

Therefore  after 1 second of lunched the object reach a height of 16 feet.

Step-by-step explanation:

When a particle is thrown vertically upward direction on that time only gravitation force is worked on it. In that case the acceleration of the particle is - g.Since gravitation force works downward direction and the displacement of the particle is upward direction that's why acceleration is negative.

When particle comes down the the acceleration of the particle is g.

Since the displacement and acceleration work on the particle in same direction.

The value of g is 9.8 m/s².

Given that, the height of the particle can measure from the equation

h=-16t^2+32t       Where t is time in second

To find out the time when the object reach a height 16 feet. We have put the value of h in the given equation.

Putting h=16 in the given equation

16= -16 t²+32

⇒16t²-32t+16=0

⇒16(t²-2t+1)=0

⇒t²-2t+1=0²         [ ∵16≠0]

⇒(t-1)²=0

⇒t-1=0

⇒t=1

Therefore  after 1 second of lunched the object reach a height of 16 feet.

Chloe purchased some dried mango and dried kiwi to make some trail mix. The dried mango cost ​$2.11 per pound and the dried kiwi
andreev551 [17]

Answer:

Number of pounds of dried mangoes Chloe bought = 3.5

Number of pounds of dried kiwi Chloe bought bough = 6.5

Step-by-step explanation:

Total number of pounds of dried fruit purchased = 10

Let number of pounds of dried mango purchased = x

Let number of pounds of dried kiwi purchased be = y

Total weight of dried fruits purchased = x+y

So, we have a sum equation as:

x+y=10

Total cost of dried fruits = $40.34

Cost of a pound of dried mango = $2.11

Cost of x pounds of dried mango in dollars can be given as = 2.11x

Cost of a dried kiwi = $5.07

Cost of y pounds of dried kiwi in dollars can be given as = 5.07y

Total cost of dried fruits in dollars = 2.11x+5.07y

So, we have a cost equation as:

2.11x+5.07y=40.34

The system of equations is :

A) x+y=10

B) 2.11x+5.07y=40.34

Solving by substitution.

Rearranging equation A, to solve for y in terms of x

Subtracting both sides by x

x+y-x=10-x

y=10-x

Substituting value of y we got from A into equation B.

2.11x+5.07(10-x)=40.34

Using distribution.

2.11x+50.7-5.07x=40.34

Simplifying.

-2.96x+50.7=40.34

Subtracting both sides by 50.7.

-2.96x+50.7-50.7=40.34-50.7

-2.96x=-10.36

Dividing both sides by -2.96.

\frac{-2.96x}{-2.96}=\frac{-10.36}{-2.96}

∴ x=3.5

We can plugin x=3.5 in the rearranged equation A to get value of y

y=10-3.5

∴ y=6.5

So, number of pounds of dried mangoes Chloe bought = 3.5

Number of pounds of dried kiwi Chloe bought bough = 6.5
