Answer:
51
Step-by-step explanation:
Let s represent the number of seats in a row. Then the number of rows is (s-9) and the total number of seats is ...
s(s-9) = 2142
s² -9s +4.5² = 2142 +4.5² . . . . . complete the square
(s -4.5) = √2162.25 . . . . . . . . take the positive square root
s = 4.5 +46.5 = 51 . . . . . . . add 4.5
The number of seats in each row is 51.

Step-by-step explanation:
From the piecewise function given in the picture,
f(x) = k³ + x If x < 3
= [tex]\frac{16}{k^2-x}[/tex] If x ≥ 3
Here, function is discontinuous at x = 3
If the function is continuous at x = 3 then,
k³ + 3 = [tex]\frac{16}{k^2-3}[/tex]
(k³ + 3)(k² - 3) = 16
k⁵ - 3k³ + 3k² - 9 = 16
k⁵ - 3k³ +3k² - 25 = 0
By using a graphing tool we can get the point where k = 2.081.

A new bank customer with $5,000 wants to open a money market account. The bank is offering a
simple interest rate of 1.5%.
a. How much interest will the customer earn in 30 years?
b. What will the account balance be after 30 years?
Answer:
Amount of interest in 30 year = $2,250
Account balance after 30 year = $7,250
Step-by-step explanation:
Given:
Amount deposit P = $5,000
Simple interest rate = 1.5% = 0.015
Find:
Amount of interest in 30 year
Account balance after 30 year
Computation:
Interest = PRT
Amount of interest in 30 year = (5,000)(0.015)(30)
Amount of interest in 30 year = $2,250
Account balance after 30 year = P + I
Account balance after 30 year = $5,000 + $2,250
Account balance after 30 year = $7,250

If 3=7k and 7= m/2 then mk=
Answer:
Step-by-step explanation:
3=7k
Meaning k = 3/7
7=m/2
Meaning m = 7*2 = 14
Therefore mk = 3/7*14 = 6
The product of m and k i.e. mk is 6.
Algebraic terms usually consist of two or more variables with their arithmetic operations.
From the parameters given:
3 = 7k ---- (1)
7 = m/2 ---- (2)
We are to determine mkFrom equation (1), let's make (k) the subject, we have:
k = 3/7
From equation (2), let's make (m) the subject, we have:
m = 7 × 2
m = 14
The product of m and k which is mk will now be:
= 14 × 3/7
= 2 × 3
= 6

The Honda Accord was named the best midsized car for resale value for by the Kelley Blue Book (Kelley Blue Book website). The file AutoResale contains mileage, age, and selling price for a sample of 33 Honda Accords. Click on the datafile logo to reference the data. The estimated regression equation is Selling price = 20385.25049 - 0.03739 Mileage - 686.33668 age. Round your answers to the nearest dollar. a. Estimate the selling price of a four-year-old Honda Accord with mileage of 40,000 miles.
answer : ≈ $16144
Step-by-step explanation:
Determine the selling price of a four-year-old Honda Accord with mileage of 40,000 miles.
Given data :
Age= 4 year, Mileage=40,000 miles
Hence the selling price
= 20385.25049 - 0.03739 Mileage - 686.33668 age
= 20385.25049 - 0.03739(40,000) - 686.33668 ( 4 )
= $16144.32
Vertices A (-1,1) and Vertices B (-4,1) of Square ABCD are shown below. What is the perimeter?
Hint: find the Vertices C and D first, then find the perimeter. A square is the same length all around!
Answer:
12
Step-by-step explanation:
Distance from (-4,1)to (-1,1) =|-4|-|-1|=3
Side of square =3
Since each side of square is equal.
3x4=12
If vertices A (-1,1) and vertices B (-4,1) of Square ABCD then perimeter of the square ABCD is 12 units.
What is Distance?The length along a line or line segment between two points on the line or line segment.
The distance between A and B is 3 units, so the distance between B and C must also be 3 units since the square has equal sides.
The coordinates of C are (-4, -2) since it is directly below B.
The distance between C and D is 5 units since it is a horizontal line between the x-coordinates of C and D.
The coordinates of D are (-1, -2) since it is directly to the right of C.
Now we have the coordinates of all four vertices
A (-1,1), B (-4,1), C (-4,-2), and D (-1,-2).
To find the perimeter, we add up the lengths of all four sides:
AB = BC = CD = AD
= √[(xB - xA)² + (yB - yA)²]
= √[(-4 - (-1))² + (1 - 1)²]
= 3
So the perimeter is P = AB + BC + CD + AD
= 3 + 3 + 5 + 3
= 14
Therefore, the perimeter of the square ABCD is 12 units.

In the polyhedron above x=5 mm, y=9 mm, and z=4 mm. The volume of the polyhedron is _____ mm3. Round your answer to the tenths place.
Answer:
180 mm³
Step-by-step explanation:
The polyhedron is an oblique rectangular prism
Area of the oblique rectangular prism = base area * height
height = z = 4 mm
Base area = L*W
L = y = 9 mm
W = x = 5 mm
Base area = 9*5 = 45 mm²
Area of the oblique rectangular prism = 45*4 = 180 mm³

hello :
note : the n th term of an arithmetic sequence is :
An =A1+(n-1)d ....a common difference is : d and A1 the first term
in this exercice : d = 33-29 =29-25= 4 A1 = 25
when : n =97 you have the 97rd term A97

How do you find distance if 1/4 inch equals 2 miles and the other location is 3 3/4 inches aprt
Answer:
Step-by-step explanation:
7/4 is not the answer
Find how many 1/4 inches are in 3 3/4 inches:
There are four 1/4 inches per inch.
3 inches x 4 = 12, there are twelve 1/4 inches in 3 inches and there are three 1/4 inches in 3/4 inch.
So there are a total of fifteen 1/4 inches in 3 3/4.
Now multiply the total 1/4 inches by 2 miles.
15 x 2 = 30 miles total.
