Answer:
4/3
Step-by-step explanation:
You want the limit as t→1 of (t³+t²-5t+3)/(t³-3t+2).
Simplified formThe fact that each polynomial evaluates to 0 at t=1 tells you that (t-1) is a factor of each. Factoring that out gives ...
[tex]\dfrac{t^3+t^2-5t+3}{t^3-3t+2}=\dfrac{(t-1)(t^2+2t-3)}{(t-1)(t^2+t-2)}=\dfrac{(t-1)(t-1)(t+3)}{(t-1)(t-1)(t+2)}\\\\=\dfrac{t+3}{t+2}[/tex]
The limit at t = 1 is found by direct substitution:
lim = (1 +3)/(1 +2) = 4/3
A hospital is trying to cut down on emergency room wait times. It is interested in the amount of time patients must wait before being called back to be examined. An investigation committee randomly surveyed 70 patients. The sample mean was 1.5 hours with a sample standard deviation of 0.5 hours.
Which distribution should you use for this problem? (Enter your answer in the form z or tdf where df is the degrees of freedom.)
The distribution that is needed for the problem that we have here is the t distribution.
What is the t distribution?With its bell-shaped structure and heavier tails, the t-distribution, commonly referred to as the Student's t-distribution, is a kind of probability distribution that resembles the normal distribution.
When there are insufficient samples or unknown variances, it is used to estimate population parameters. T-distributions have broader tails than normal distributions because they are more likely to contain extreme values.
We have tn-1
where n = 70
so that we would have
t70 - 1
= t69
Therefore we would have to use the t distribution here.

A company issues 9%, 4-year bonds with a par value of $160,000 on January 1 at a price of $165,386, when the market rate of interest was 8%. The bonds pay interest semiannually.
Simple interest is defined as the percentage of earnings on the lending for a period of time
Here,
Value of a single bond = $160,000
Issue price of bond = $165, 386
Rate of interest = 9%
the market rate of interest = 8%
Interest payment = Semi-annually
Semi-annual interest payment = Value of the single bond × rate of interest/2
= $160,000 × 0.09/2
= $7200
Thus, the amount of each semiannual interest payment is $7200.

The radius of a spherical ball is increasing at a rate of 2 cm/min. At exactly what rate (in cm2/min) is the surface area of the ball increasing when the radius is 6 cm?
The rate at which the surface area is changing when r = 6cm is 96[tex]cm^{2}[/tex]/min.
Surface area of SphereThe surface area of a sphere with radius r is given by4π[tex]r^{2}[/tex]
Given;
S = surface area at time t, and r = radius at time t
radius of a spherical ball is increasing at a rate of 2 cm/min
radius: 6cm
Area of a sphere is A = 4π[tex]r^{2}[/tex]
Step 1: Differentiate area of a spherical ball
A = 4π[tex]r^{2}[/tex]
[tex]\frac{dA}{dt}[/tex] =[tex]\frac{d}{dt}[/tex](4π[tex]r^{2}[/tex])

Tammy must choose a number between 61 and 107 that is a multiple of 3,9 and 12. Write all the numbers that she could choose
Answer:
G LCM (least common multiple) of 3, 9, and 12. After doing that, find the number that is between 61 and 107.
Step-by-step explanation:
Least common multiple (lcm) is where g finds out the number that can be divided by all the numbers (3, 9, and 12 in this case) and still come out with a whole number.
Does 4f+2(12 f−4)=3(2f−4)−f+3 have one solution, no solution, or infinitely many solutions?
Based on the calculations, this equation 4f + 2(12f − 4) = 3(2f − 4) − f + 3 has one solution, which is equal to -1/23.
What is no solution?In Mathematics, no solution is also referred to as zero solution, and an equation is said to have no solution when the left hand side and right hand side of the equation are not the same or equal.
This ultimately implies that, an equation would have no solution or zero solution when both sides of the equal sign are not the same and the variables cancel out.
From the information provided, we have the following equation:
4f + 2(12f − 4) = 3(2f − 4) − f + 3
Opening the bracket, we have:
4f + 24f - 8 = 6f - 12 - f + 3
28f - 8 = 5f - 9
By collecting like terms, we have the following:
28f - 5f = -9 + 8
23f = -1
Dividing both sides by 23, we have:
f = -1/23

What is the size of angle x?
Write a justification for your answer.
The angle x will be 34°.
From the properties of circles we get to know that the angle at the center and the angle between two tangents are always supplementary.
Supplementary angles are those which always sum to to 180°.
For example ∠HJK is supplementary to ∠HIK the their sum will come out to be 180°.
similarly ∠ROP + ∠RQP = 180°
∠RQP = 180° - ∠ROP
∠ROP is given to us 146°
After putting it in the equation above we get ∠RQP = 34°

Answer: dont be rude
Step-by-step explanation:
A medic's bag contains individually wrapped tongue depressors (each costing 4 cents) and Band-Aids (each costing 8 cents). If the materials are worth $12.48 and there are 184 individual packages in total, how many tongue depressors and Band-Aids are there?
# of Tongue Depressors:
# of Band-Aids:
The number of tongue depressors = 56
The number of Band-Aids = 128
What is an equation?
An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.
Let x be the number of tongue depressors.
Let y be the number of Band-Aids
Convert cents to dollars
1 cent = $0.01
So, 4 cents = 0.01*4 = $0.04
8 cents = 0.01* = $0.08
The materials are worth $12.48 .
This means, 0.04x+0.08y=12.48......(1)
There are 184 individual packages in total.
This means, x+y=184.......(2) => x=184-y.....(3)
Substitute (3) in (1),
0.04(184-y)+0.08y=12.48
7.36-0.04y+0.08y=12.48
=> y= 128
(3) => x=184-128=56
So, the number of tongue depressors = 56
The number of Band-Aids = 128

inches are $27.55, and Saturday rates are $29.35 per
column inch. How much should KT's Restaurant budget for
newspaper advertising for the coming year?
The budget of KT's Restaurant for newspaper advertising for the coming year is $58,533,500
Given,
The length of advertisement of KT's Restaurant in Vidalia Times in week days = 5,000
The length of advertisement of KT's Restaurant in Vidalia Times in Saturdays = 10,000
The cost of daily column = $27.55 per column inch
The cost of Saturdays = $29.35 per column inch
We have to find the budget of KT's Restaurant for newspaper advertising for the coming year;
Here,
There are approximately 53 Saturdays in a year.
So,
365 - 53 = 312
Then,
The budget of advertisement on daily column = 312 × 5000 × 27.55 = $42,978,000
The budget of advertisement on Saturday column = 53 × 10,000 × 29.35 = $1,555,500

x = 1, and x = 2 x = –6 and x = 2 x = –4 and x = 2 x = 2
The critical points of the given inequality are; x=-6 and x=2
What are the critical points of the Inequality?1) When the denominator is equal to zero, at that point, we will have a critical point.
We are given the inequality;
(2x + 5)/(x - 2) ≥ (x - 1)/(x - 2)
Thus, x - 2 = 0
x = 2.
Thus, x = 2 is a critical point
2) Simplify the numerator to get the expression such that p(x) ≥ 0 or p(x) ≤ 0.
Thus, at p(x) = zero, we have other critical point(s)
Multiply both sides by (x - 2) to get;
2x + 5 = x - 1

Josephine invests £3,500 in a bank account which pays annual compound interest of 4.5%. How much money will she have in the bank after: (a) 2 years, (b) 3 years?
Josephine have £3882.9 amount after 2 years and £3994.9 amount after 3 years.
Using the formula of compound interest we can find the amount after t years compounded annually at the r per cent rate.
The formula of compound interest is as follows,
[tex]A=p(1+\frac{r}{100} )^t[/tex]
Where P is the principal value, A is the amount, r is the rate and t is the time.
Here we have a principal value of £3,500 and a rate is 4.5%.
Now, finding the amount after 2 years by putting the values in the formula of compound interest,
[tex]A=p(1+\frac{r}{100} )^t\\\\A=3500(1+\frac{4.5}{100} )^2\\\\A=3500(1+0.045 )^2\\A=3500(1.045)^2\\A=3500\times1.092025\\A=3882.0875[/tex]
So, After 2 years Josephine will have £3882.9.
Now, finding the amount after 3 years,
[tex]A=p(1+\frac{r}{100} )^t\\\\A=3500(1+\frac{4.5}{100} )^3\\\\A=3500(1+0.045 )^3\\A=3500(1.045)^3\\A=3500\times1.141166125\\A=3994.0814375[/tex]
So, After 3 years Josephine will have £3994.9.
Therefore, After 2 years Josephine will have £3882.9 and after 3 years Josephine will have £3994.9 when 4.5% interest is compounded annually.
