Answer: 1.41 seconds
Step-by-step explanation:
The problem gives the initial velocity by saying "dropped." This indicates a velocity of zero. Acceleration can also be found because the object is in free fall. It would experience the acceleration of gravity. We can use the kinematic equation:
[tex](y_f-y_i)=V_it+\frac{1}{2}at^2[/tex]
The velocity term completely cancels because the object was dropped with an initial velocity of 0.
[tex](18-50)=\frac{1}{2} (32.17)t^2\\[/tex]
[tex]-32=-16.085t^2\\t=\sqrt{1.989} =1.41s[/tex]

The total cost C for a manufacturer during a given time period is a function of the number N of items produced during that period. To determine a formula for the total cost, we need to know the manufacturer's fixed costs (covering things such as plant maintenance and insurance), as well as the cost for each unit produced, which is called the variable cost. To find the total cost, we multiply the variable cost by the number of items produced during that period and then add the fixed costs.
a. Use a formula to express the total cost C of this manufacturer in a month as a function of the number of widgets produced in a month. Be sure to state the units you use.
b. Express using functional notation the total cost if there are 250 widgets produced in a month, and then calculate that value.
Answer:
(a) C = 9000 + 15N
(b) Cost of 250 widgets is $12750
Step-by-step explanation:
The question has missing details. See attachment for complete question
Solving (a): An expression for total cost.
The expression is generated using:
[tex]Total\ Cost = Fixed\ Cost + Variable\ Cost * Number\ of\ Items[/tex]
From the given parameters:
[tex]Fixed\ Cost = 9000[/tex]
[tex]Variable\ Cost = 15[/tex]
[tex]Number\ of\ Items = N[/tex]
So, the expression becomes:
[tex]C = 9000 + 15 * N[/tex]
[tex]C = 9000 + 15 N[/tex]
Solving (b): Cost of 250 widgets
In this case:
[tex]N =250[/tex]
Substitute 250 for N in [tex]C = 9000 + 15 N[/tex]
[tex]C = 9000 + 15 * 250[/tex]
[tex]C = 9000 + 3750[/tex]
[tex]C = 12750[/tex]

a baseball team wins 45% what fraction of the games do they win
Answer:
= 9/20
Step-by-step explanation:
45% = 45/100
= 0.45
= 0.45/1 × 100/100
= 45/100
= 9/20
The bus fare in a city is $2.00. People who use the bus have the option of purchasing a monthly coupon book for $28.00. With the coupon book, the fare is reduced to $1.00. Determine the number of times in a month the bus can be used so that the total monthly cost without the coupon book is the same as the total monthly cost with the coupon book
Answer:
56 = 56
Step-by-step explanation:
Given:
Bus fare = $2.00
coupon book = 28.00
bus fare w/ coupon book = $1.00
let x be the number of bus rides.
2.00x = 1.00x + 28.00
2.00x - 1.00x = 28.00
1x = 28.00
x = 28.00
24 bus rides for both to have the same cost.
2.00x = 1.00x + 28
2.00(28) = 1.00(28) + 28
56 = 28 + 28
56 = 56

— 3х + Зу = - 24
how do i convert to slope intercept form
Answer:
y = x - 8
Step-by-step explanation:
Slope intercept form: y = mx + b, where b is the y-intercept.
Solve the given equation for y and then compare the result with this y = mx + b:
3y = 3x - 24
Dividing all three terms by 3 yields:
y = x - 8 (answer). The slope is 1 and the y-intercept is -8.
The first three terms of a geometric sequence are as follows.
-7, 14, -28
Find the next two terms of this sequence.
Give exact values (not decimal approximations).
-7, 14, -28, CI
-7,14,-28,56,-112
an = a1(r)^n-1
a4 = -7(-2)^4-1
a4 = -7(-2)³
a4 = -7(-8)
a4 = 56
an = a1(r)^n-1
a5 = -7(-2)^5-1
a5 = -7(-2)⁴
a5 = -7(16)
a5 = -112
#CarryOnLearningApproximately__ tons of LNG will be produced in may, and approximately 104,489 tons will be produced in___
Help plz :,)
Answer:
Step-by-step explanation:
For all Plato users
Approximately 94437.825 tons of LNG will be produced in May, and approximately 104,489 tons will be produced in October month.
Given that, the production of LNG by an energy company increases by 1.7% each month.
How to find the percentage of the number?Convert the problem to an equation using the percentage formula: P% * X = Y.
Production in April month=91,307+1.7% of 91,307
=91,307+1.7% ×91,307
=92,859.219 tons
Production in May month=92,859.219×(1+1.7%)
=94437.825 tons
Production in June month=94437.825×(1+1.7%)=96,043 tons
Production in July month=96,043×(1+1.7%)=97,676 tons
Production in August month=97,676×(1+1.7%)=99,336.49 tons
Production in September month=99,336.49×(1+1.7%)=1,01,025.21 tons
Production in October month=1,01,025.21×(1+1.7%)=1,04,489 tons
94437.825 tons of LNG will be produced in May, and 104,489 tons will be produced in October month.

The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000 miles and a standard deviation of 8,300 miles. What proportion of these tires last between 40,000 and 45,000 miles
Answer:
P [ 40000 ≤ X ≤ 45000 ] = 0,02773 or 2,8 %
Step-by-step explanation:
P [ 40000 ≤ X ≤ 45000 ] = ?
To find the probablity P [ X ≤ 40000 ] = ?
z(s) = ( X - x ) / σ
z(s)= ( 40000 - 6000 )/ 8300
z(s) = -20000/8300
z(s) ≈ - 2,41
Then
from z-table we find P [ X ≤ 40000] = 0,00820
Now again:
For P [ X ≤ 45000 ]
z₂ = ( X - x ) / σ
z₂ = ( 45000 - 6000 ) / 8300
z₂ = - 15000 / 8300
z₂ = - 1,8072
z₂ ≈ 1,81
From z - table
For P [ X ≤ 45000 ] = 0,03593
Then:
P [ 40000 ≤ X ≤ 45000 ] = 0,03593 - 0,00820
P [ 40000 ≤ X ≤ 45000 ] = 0,02773 or 2,8 %
Two publishers have offered Melanie Thompson a deal on her new
book Sugar-Free Culinary Classics. The first has offered to pay
her $82,000 up front and a $5.50 royalty for every book it
sells. The second has offered to pay $68,000 up front and a
$6.75 royalty for every book it sells. Over what range of book
sales will Melanie make more from the second publisher than she
will from the first?
Answer:
Step-by-step explanation:
68000+6.75b>82000+5.5b. subtract 5.5b from both sides
68000+1.25b>82000. subtract 68000 from both sides
1.25b>14000. divide both sides by 1.25
b>11200
So she must sell more than 11500 books to make more with second publisher.

here, we have,
to determine the situation:
The given parameters are:
Initial = 5200
Rate = 5%
Because the population by 5% every year, then the situation is a geometric sequence.
The common ratio is then calculated as:
Ratio = 1 + Rate
This gives
Ratio = 1 + 5%
Evaluate
Ratio = 1.05
