According to the given question.
We have a polynomial 18u - 8u^2 -9 + u^7.
As we know that the leading coefficient of a polynomial is the coefficient of the leading term.
And the highest and the greatest power of a variable in a polynomial equation is called degree of a polynomial.
Here, the leading term of the given polynomial is u^7. Therefore, the leading coefficient of a polynomial is 1.
And the degree of the polynomial is 7.

The amount borrowed is $87,000, the annual interest rate is 6%, the number of payments per year is 12, the loan term is 19 years, and the payment amount is $145,920.
Given that, an individual borrowed $87,000 an APR of 6%, which will be paid off with monthly payments of $640 for 19 years.
What is APR?APR is annual percentage rate. APR can be found with the formula, APR = ((Interest + Fees / Principal or Loan amount) / N or Number of days in loan term)) x 365 x 100.
From the given question,
P=$87,000, R=6%, monthly payment=$640 and loan term = 19 years.
Total amount = Total number of months × Monthly payment
= 19 × 12 × 640
=$1,45,920
Therefore, the amount borrowed is $87,000, the annual interest rate is 6%, the number of payments per year is 12, the loan term is 19 years, and the payment amount is $145,920.

The vertical position y (in feet) of a rock t seconds after it was dropped from a cliff is given by the formula y equals short dash -16 t squared plus 4 t plus 380. The base of the cliff corresponds to y = 0. After how many seconds will the rock hit the ground at the base of the cliff?
The seconds that it will take the rock hit the ground at the base of the cliff is 5 seconds
How to calculate the value?Based on the information given, it should be noted that the expression given is:
y = -16t² + 4t +380
We have to divide through by 4. Therefore,
y = -4t² + t + 95
y = -4t² + 20t - 19t + 95
y = -4t(t - 5) - 19(t - 5)
t - 5 = 0
t = 0 + 5

What is the domain of the function y = square root x+6 -7?
Answer:
-6 ≤ x < ∞
Step-by-step explanation:
You want the domain of the function y = √(x+6) -7.
DomainThe domain of a function is the set of x-values for which the function is defined. On a graph, it is the horizontal extent of the graph.
The square root function is undefined for negative arguments, so that limits the domain of the given function:
x+6 ≥ 0
x ≥ -6 . . . . . domain of the given function
__
Additional comment
When the domain is written in interval notation, both the left and right ends of the interval must be specified.
[-6, ∞)
The square bracket identifies -6 as being part of the domain. The parenthesis is used with ∞, because that number has no specific value.

Brody's age is 3 years less than twice Trinity's age? The sum of their ages is 30.
Answer: Brody's Age is 19 and Trinity's age is 11
Step-by-step explanation:
x = Trinity's age
2x-3= Brody's age
The sum of the ages is 30, so
x + (2x-3) = 30
3x - 3 = 30
add 3 to both sides 30 turns into 33 so,
3x = 33
divide by 3 both sides
x = 11 which is trinity's age and plug x into 2x - 3 which is 19 so that's Brody's age.

age if Ali is older?
The ratio of Ali's age to Steve's is 2 to 1.
How to find the ratio of Ali age to Steve age ?The sum of the ages of Steve and Ali is three times the difference of their ages.
Therefore,
let
x = age of Steve
y = age of Ali
Hence,
x + y = 3(y - x)
x + y = 3y - 3x
Therefore,
x + 3x = 3y - y
4x = 2y
divide both side by 2
4x / 2 = 2y / 2
2x = y

hundredths place include zeros so that it does
The volume of aggregate that she needs to build the patio is 13.18 ft^3
How many cubic feet of aggregate would she need to build the walkway?
We know that the backyard is 14ft long, 6 feet wide and 4 inches deep.
Rememeber that:
1ft = 12 in
Then:
4 in = (4/12) ft = (1/3) ft
Then the volume of the backyard is:
V = (14ft)*(6ft)*(1/3 ft) = 28ft^3
Now we know that we have a mix of 4 parts aggregate to 4.5 parts loose cement that need to fill these 28 cubic feet.
Note that:
4 + 4.5 = 8.5
How many times we have 8.5 in 28?
28/8.5 = 3.294
Now for each of these we have 4 parts of aggregate, then the volume of aggregate that we need is:

Ordered: 130 mg. Available: 1 gr/tablet. How many tablets should be given? ________
Answer:
2
Step-by-step explanation:
1gr=100mg
130-100=30
No tablets should be given since the ordered quantity of 130 mg is less than the available quantity per tablet of 1 g.
How many tablets should be given?We have the following data:
Ordered amount: 130 mg
Available amount per tablet: 1 g
To decide the number of tablets to be given, we have to be make sure the units are steady. Let's change over the ordered amount to grams:
130 mg = 130/1000 g = 0.13 g
Presently, we are able calculate the number of tablets:
Number of tablets = Ordered amount / Available amount per tablet
Number of tablets = 0.13 g / 1 g = 0.13 tablets
Since we cannot administer a fraction of a tablet, we round the result to the closest whole number. In this case, 0.13 is less than 0.5, so we round down:
Number of tablets to be given = tablets
Hence, no tablets ought to be given since the ordered amount of 130 mg is less than the available amount per tablet of 1 g.

What is defined as the rectangle?A rectangle is a closed two-dimensional shape with four sides, four corners, and four right angles (90°).
A rectangle's opposite sides are equal as well as parallel. Because a rectangle is a 2-D shape, it has two dimensions: length and width. The length of the rectangle is the longer side, and the width is indeed the shorter side.Now, as per the given question;
The area of the rectangular floor is given as two hundred thirty-nine and one-fourth square feet.
Thus,
A = 239.25 feet
The width is fourteen and one-half feet.
Thus,
W = 14.5 feet
The formula for area is;
A = L×B (L is the length)
Put the values;
239.25 = L×14.5
L = 239.25/14.5
L = 16.5 feet
The rectangular perimeter is;
P = 2(L + B)
P = 2(16.5 + 14.5)
P = 62 feet

two investments totaling $28,000 produce annual income of $1435. One investment yields 9% per year, while the other yields 2% per year. How much is invested at each rate
The investment amount at 9% rate is $12500 and the investment
amount at 2% rate is $15500
What is mathematical expression?
A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Let x be the amount invested at 9% rate.
And (28000−x) be the amount invested at 2% rate.
The total annual income is $1435
Let us find the amount invested at 9% rate:
x9%+2%(28000−x)=1435
9%+2%(28000−x)=1435
0.09x+0.02(28000−x)=1435
0.09x+560−0.02x=1435
0.09x−0.02x=1435−560
0.07x=875
x=875/0.07
x=12500
Let us find the investment amount at 2% rate:
⇒28000−x
⇒28000−12500
⇒15500
Therefore, the investment amount at 9% rate is $12500 and the investment amount at 2% rate is $15500.

Why does the graph look like a series of steps rather than a smooth curve? Why is a hollow circle needed at the beginning of each step(except the first)?
Answer:
the cost function is defined as a step function
Step-by-step explanation:
You want to know why a cost graph has steps.
Cost StepsIn the US, current first class postage rates for appropriately sized envelopes are 60¢ for the first ounce, and 24¢ for each additional ounce.
Envelopes below a certain weight cannot be mailed, and above that minimum (up to at most one ounce), the cost will be 60¢. That is, the first step is at cost=60¢, and extends from some minimum weight up to 1 ounce at that cost.
Above one ounce -- even very slightly above, the cost is 84¢. There is no weight where the cost is 61¢ or 62¢ or any other number between 60¢ and 84¢.
For the purpose of determining cost, the weight is rounded up to the next higher ounce. This guarantees that cost values will be a discrete set of values.
Continuous weightsThe weight can take on any real value. This is reflected in the continuous horizontal line at each level of cost.
The hollow circle at 1 ounce on the second step means that the cost for one ounce is not the value of that second step. The filled circle indicates the cost for one ounce is the value of the first step. The hollow circle also indicates that weights arbitrarily close to 1 ounce, but greater, will cost the same as for 2 ounces.
__
Additional comment
The minimum weight envelope that can be mailed first class will be a function of its size. Outside a certain size and weight range, the envelope will not be "machinable," so will incur an extra charge.
