Answer:
16
Step-by-step explanation:
let x be a positive integer
mathematically, the statement: “The product of two consecutive positive integers is 194 more than the next integer” means x(x + 1) - 194 = x + 2
………………………………
Solving the equation x(x + 1) - 194 = x + 2 for x :
x(x + 1) - 194 = x + 2
⇔ x² + x - 194 = x + 2
⇔ x² - 194 = 2
⇔ x² = 196
⇔ x = 14 or x = -14
Since -14 < 0 then the solution to our equation is x = 14
Therefore
The largest integer of the three is x + 2 = 14 + 2 = 16
Verification:
14 × 15 − 194 = 210 − 194 = 16

Answer:
(6,2)
Step-by-step explanation:
If you are looking for the coordinates then that is the correct answer.
Answer:
(6,2)
Step-by-step explanation:
Because the Y axis is vertical so you would move down and subtract 5 from the 7. Your X would stay the same. So the answer will be (6,2)

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position. The correct option is D.
What are coordinates?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
For a function to be even, the graph of the function should be such that it should be symmetrical about the x-axis. Therefore, the points of the graph will be the opposite.
The 7 points of option D can be plotted as shown below, which is symmetrical about the X-axis. Hence, the correct option is D.

Recall that the area of a trapezoid is equal to the average of its bases times its height.
For the trapezoids shown here, each base corresponds to the value of [tex]y=2x^2[/tex] when [tex]x[/tex] is one of the endpoints of some interval, while the height is the length of that interval.
On the interval [-2, -1], the trapezoids has bases 2(-2)² = 8 and 2(-1)² = 2, and "height" -1 - (-2) = 1. Then its area is (8 + 2)/2 × 1 = 5.
On the interval [-1, 0], one of the bases is 2(-1)² = 2 and the other is 2(0)² = 0, and the height is again 0 - (-1) = 1. Then the trapezoid's/triangle's area is (2 + 0)/2 × 1 = 1.
Then the total area under the curve [tex]y=2x^2[/tex] on the interval [-2, 0] is approximately 5 + 1 = 6.
Compare this to the actual value of the area given by the definite integral,
[tex]\displaystyle \int_{-2}^0 2x^2 \, dx = \frac{16}3 \approx 5.333\ldots[/tex]

Penny attended a four year state college. She took out a student loan to pay for her tuition and room & board for the four years she was attending the college. Her tuition fees were $6,970 per year, and the cost of her room and board was $11,320 per year. Now that she has graduated, she will have to start paying back her loan. Fortunately, Penny has a grace period of one year before she has to start paying back the loan. Her loan details are as follows: there is a fixed-rate interest of 4.5% and the interest compounds each month. During her one year grace period, interest will accrue on the loan, so that when she has to start paying the loan back she will owe more than what she owes now. Her goal is to be able to payoff the loan in 10 years.
What is the new loan amount after the one-year grace period (remember that interest will accrue on the loan during this initial 12-month period that she is not paying anything back on the loan)? This is the amount that she will be responsible for paying back. (Round your answer to the nearest whole dollar)
Given that she can pay back the loan in full after 10 years of payments, what is the total amount she will end up paying back (both principal and interest that has accrued over the 10 years)? And how much will her monthly payments on the loan be for those 10 years? (Round your answers to the nearest whole dollar)
The loan amount is given as $76521
We first have to calculate the total amount of tuition
6970 x 4 + 11320 x 4
= 73160
a. How to solve for the new loan amount[tex]73160 (1+\frac{\frac{4.5}{100} }{12} )^1^2[/tex]
= 73160 x (1 + 0.00375)¹²
= 76520.95
Hence the new loan amount after agrace period of 1 year = $76521
b. PV = $76521
i = [tex]\frac{4.5/100}{12}[/tex]
= 0.00375
t = 10 years
[tex]PMT[\frac{1-(1+0.00375)^-^1^2^0}{0.0375} ]= 76521[/tex]
pmt = 793. 05
The monthly payment is $793. 05.
In ten years the total payment is 793.05 x 10 x 12
= 95166
Difference = 95166 - 76521
= $18645
In ten years her ,monthly payment on the loan would be $18645.

Converting Normal distribution to standard normal because A normal distribution is determined by two parameters the mean and the variance. A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. Hence it's easy to work with standard normal distribution.

A recent forest fire near Littleville destroyed four-fifths of the trees in Bigtree National Forest. The
forest covers 4920 km2. There is now about 30 tons of salvageable wood per km2 in the burned area. The
part of the forest that was not destroyed by fire will not be open to the salvagers. Assuming the trees are
evenly distributed throughout the park, about how long will it take to remove all the salvageable wood at
a rate of 53 1/2 tons per day? Round your answer to the nearest whole number.
Step-by-step explanation:
the whole forest is 4920 km².
4/5 if that was destroyed with salvageable wood :
4/5 × 4920 = 3,936 km²
there is 30 tons of salvageable wood per km², so in total :
3936 × 30 = 118,080 tons.
the wood can be removed at av rate of 53.5 tons per day.
how many days until cleaned up ?
as many days as 53.5 fits into the total amount of 118,080 :
118080 / 53.5 = 2,207.102804... days.
so, it will take about 2,207 days to remove all the salvageable wood.

The locus of the point represented by the equation y = 3•x + 2, indicates that the point (1, 5) is on the locus of the point.
How can the location of the point in relation to the point be found?The distance from the x-axis is the y-value
The distance from the y-axis is the x-value
Therefore;
The equation of the locus of the point is presented as follows;
y = 3•x + 2When x = 1, y = 3 × 1 + 2 = 5
When x = 1, y= 5

Two side lengths of a triangle are $11$ and $17$. What is the longest possible integer length of the third side of the triangle
The longest possible integer length of the third side of the triangle is 6 < x < 28
The sum of any two sides must be greater than the third side for a triangle to exist
let the third side be x
x + 11 > 17 and x + 17 > 11 and 11 + 17 > x
x > 6 and x > - 6 and x < 28
The longest possible integer length of the third side of the triangle is 6 < x < 28
The length of the 3 sides of a triangle needs to always be among (however no longer the same) the sum and the difference of the opposite two sides. As an example, take the instance of two, 6, and seven. and. consequently, the third side period should be extra than 4 and less than 8.

A box has dimensions of 2.5 cm by 3.0 cm by 4.0 cm. The volume of the box in milliliters and liters is:
Answer:
30000 milliliters
0.03 liters
Step-by-step explanation:
The volume of the box is 2.5 x 3.0 x 4.0 = 30 cc
There are 1000 ml in 1 cc so 30cc = 30 x 1000 = 30000 ml
There are 1000 cc in 1 liter so 30 cc = 30/1000 = 0.03 liters
The volume of the box is 30 mL or 0.03 L.
What is volume?Volume is a metric magnitude that is defined as the extension in three dimensions of a region of space. Volume is defined as the amount of space occupied by the object or figure in three-dimensional space. Volume is measured in cubic units.
The volume of this prism depends on its three dimensions and is calculated as the multiplication of these dimensions,
Volume= Dimension 1× Dimension 2× Dimension 3
The volume of the box = 2.5 x 3.0 x 4.0 = 30 cc
There are 1000 ml in 1 cc so 30cc = 30 x 1000 = 30000 ml
There are 1000 cc in 1 liter so 30 cc = 30/1000 = 0.03 liters
Hence, the volume of the box is 30 mL or 0.03 L.

using Pythagoras' identity in the right triangle
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , then
(x + 1)² + (x + 3)² = (x + 5)² ← expand all factors using FOIL
x² + 2x + 1 + x² + 6x + 9 = x² + 10x + 25 , that is
2x² + 8x + 10 = x² + 10x + 25 ← subtract x² + 10x + 25 from both sides
x² - 2x - 15 = 0 ← in standard form

The population of a town was 25,00 people then 3,200 people moved away.What was the percent of decrease
Answer:
-12.8 %
Step-by-step explanation:
-3200 / 25 000 x 100% = - 12.8 %
Answer:
Your answer is -12.8%
Step-by-step explanation:
To calculate the percent decrease, we:
Find the difference between the new value and the original
Divide the number by the original
Multiply by 100 and the % symbol.
The population of the town originally had 25,000. 3,200 people moved away. This means that the new population is 21,800.
21,800-25,000=-3,200
-3,200/25,000=-0.128
-0.128(100)=-12.8%
The towns population decreased by 12.8%.
