If an object is dropped from a height of 85 feet, the function h(t) = -16t2 +85 gives the height
of the object after t seconds. Approximately, when will the object hit the ground?

Answers

Answer 1

Answer:

Step-by-step explanation: h(t)=-16t2+85

Let h(t)=0 to find when the object will hit the ground

0=-16t2+85

Solve for t=?

We need to get t term on its own

Take 85 from both sides

0-85=-16t2+85-85

-85=-16t2

To get t term on its own

Divide both sides by -16

-85/-16=-16t2/-16

5.3=t2

We have to solve for t squared that means we must take the square root of both sides

the square root of 5.3=gives + or - 2.3 seconds we can't have negative time so discard -2.3 seconds

Bob invested $2,500 in an account earning 3.4% annual interest that is compounded semi-annually. How long will it take the investment to triple?

(Round your answer to the nearest hundredth.)

Answers

We can conclude that it will take Bob 10 years and 10 months to triple his investment when the compounding is happening semi-annually.

What is compounding?

Compounding is the method through which interest is added to both the principal balance already in place and the interest that has already been paid.

Thus, compounding can be thought of as interest on interest, with the result that returns on interest are magnified over time, or the so-called "magic of compounding."

So, the time that will be taken to make the investment triple is:

Amount invested: $2500

Interest rate: 3.4%

Compounding: Semiannually

Now, consider a period of 2 years:

3.4 * 6/12 = 1.7%

The interest rate that is effective will be 1.7%.

Currently, the future value of the compounded rate at 1.7% for a period of 65 factors equals 2.9913.

Consequently, the value will be $2,500 2.9913 = 7,478.25.

65 months divided by six years equals 10.833 years in total.

0.833 * 12 makes up  10 months a year.

Therefore, we can conclude that it will take Bob 10 years and 10 months to triple his investment when the compounding is happening semi-annually.

In this activity, you will create a function from two points that satisfy it. A linear function passes through the points ( - 2 , 3 ) and ( - 3 , 5 ) . Complete the following tasks to find the equation of the function. Part A To find the equation, first find the rate of change. What is the rate of change for the linear function that passes through the two points?

Answers

The linear function would be y = -4x - 7 which passes through the points (- 2 , 3 ) and ( - 3 , 5 ).

Given that linear function passes through the points (- 2 , 3 ) and ( - 3 , 5 ).

Let the required line would be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

x₁ = -2, y₁ = 3

x₂ = -3, y₂ = 5

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

Substitute values in the equation, we get

⇒ y - 3 = (5 - 1)/(-3 - (-2))[x -(-2)]

⇒ y - 3 = (4)/(-1)[x +2]

⇒ y - 1 = -4(x +2)

⇒ y = -4x - 8 + 1

⇒ y = -4x - 7

Therefore, the linear function would be y = -4x - 7 which passes through the points (- 2 , 3 ) and ( - 3 , 5 ).

What is triangle?

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

Let ΔADE and ΔABC are two triangles.

Given: DE∥BC

To prove:  DB/AD = EC/AE

ΔADE and ΔAC share ∠A

∠A ≅∠A  reflexive property

DE∥BC is given

∠ADE ≅ ∠B   because they are corresponding angles when transversal

            AB cuts parallel lines DE and BC  

ΔADE ∽ ΔABC  a pair of angles in each are congruent.

AB / AD = AC / AE

because corresponding sides of similar triangle's are proportional.

Now subtract 1 from each side

AB / AD - 1 = AC / AE - 1

Answers

The function that relates the distance traveled to the time is given as follows:

d = vt.

In which v is the average velocity during the time traveled.

What is the relation between velocity, distance and time?

The average velocity is calculated as the division of the total distance by the total time, hence the following equation is built to model the proportional relationship between these variables:

v = d/t.

In this problem, we want to relate the distance traveled to the time, hence we have to solve the expression for d, as follows:

d = v x t

d = vt.

(applying cross multiplication to isolate the variable d).

Fraction represents a part of a whole, or more generally, any number of equal parts. In everyday English, fractions represent how many parts of a particular size are there.

For positive common divisors, the numerator and denominator are natural numbers. The numerator represents the number of equal parts and the denominator shows the number of parts that make up the unit or whole. A zero part can never make up a whole, so the denominator is never zero.

It is given that a recipe calls for 5 teaspoons of seasoning for every 6 batches of chilli.

For  6 batches of chilli, number of teaspoons of seasoning needed = 5

For 1 batch of chilli, number of teaspoons of seasoning needed = 5/6

For  102 batches of chilli, number of teaspoons of seasoning needed = [tex]\frac{5}{6}\times 102[/tex] = 85

Adding Fractions:

The fractions that have the same denominator are like fractions, to add like fractions directly, But if the denominators are not the same then we need to change their denominators to the same then we can add the fractions.  

To make denominators as same we need to take the LCM of denominators of two fractions.  

Here we have

Jonah ran 1(3)/(4) laps on Monday

=> 1 3/4 = 7/4 laps

On Tuesday he ran 2(3)/(10) laps

=> 2 3/10 = 23/10 laps

On Wednesday he ran 6(1)/(5) laps

=> 6 1/5 = 31/5 laps

The total number of laps ran combining Monday and Tuesday

= 7/4 laps + 23/10 laps  

= (35 + 46)/20         [ take Lcm of 4, 10 i.e 20 ]  

= 81/20

From the above calculations,

Jonah ran 81/20 laps on combining Monday and Tuesdays

The difference between Wednesday's counted laps and Monday, and Tuesday's counted laps

= 31/5 - 81/20

= (140 - 81)/20             [ Take Lcm of 5, 20 i.e 20 ]
