Suppose that prices increase 2.5% each year for 10 years. How much will a jacket that costs 100 today cost in 10 years?
Answer:
$125
Step-by-step explanation:
Find out what the percentage increase is in ten years.
2.5%->change to decimal thingy (divide by 100) 0.025 then multiply it by the total amount of years(10): 0.025(10)= 0.25- 25%
The cost percentage in 10 years is 25%
Next multiply your new percentage by the jacket's original cost: 0.25(100)=25
So $25 is the amount that the jacket has increased over ten years
Add 25 to 100 to fin the cost of the jacket in 10 years.

which is a correct classification of DEF with vertics D(-3,2) E(-2,3) and F(1,0)
The correct classification of DEF is a right-angled scalene triangle.
We are given three vertices D(-3, 2), E(-2, 3), and F(1, 0).The length of the side DE is √[(3-2)² + (-2-(-3))²] = √2.The length of the side EF is √[(0-3)² + (1-(-2))²] = 3√2.The length of the side FD is √[(2-0)² + (-3-1)²] = 2√5.The lengths of all the sides of the triangle are unequal.Thus, DEF is a scalene triangle.Apply the Pythagorean theorem.We notice that :DE² + EF² = FD²(√2)² + (3√2)² = (2√5)²2 + 18 = 2020 = 20Thus, DEF is also a right-angled triangle.Hence, DEF is a right-angled scalene triangle.To learn more about scalene triangle, visit :

If sides BD and DC have the same length, what is the length of side BC?
The length of side BC, |BC|, is 2 units. The correct option is C. 2 units
Calculating lengthFrom the question, we are to determine the length of side BC
First, we will determine the length of side BD
From Pythagorean theorem, we can write that
|BD|² = |AB|² + |AD|²
From the given information,
|AB| = 1
|AD| = 1
Thus,
|BD|² = 1² + 1²
|BD|² = 1 + 1
|BD|² = 2
|BD| = √2
Also, we can write that
|BC|² = |BD|² + |DC|²
From the given information,
|BD| = |DC|
Thus,
|BC|² = (√2)² + (√2)²
|BC|² = 2 + 2
|BC|² = 4
|BC| = √4
|BC| = 2
Hence, side BC is 2 units

How to calculate the value?It should be noted that based on the information given in the survey, 2/3 of the lions said that they were happy to serve as King of the forest, while another 1/9 thought it was way too much responsibility and 14 lions gave one of these two answers.
The total lions that were surveyed will be illustrated thus:
Let the total number of lions be x.
Therefore, (2/3 + 1/9)x = 14
= 7x/9 = 14
Cross multiply
7x = 9 × 14
x = (9 × 14) / 7
x = 9 × 2
x = 18

Write an equation of the line passing through point P (0,1) that is parallel to the line y=-2x+3
The equation of the line passing through point P (0,1) = y=2x-1
What is Equation of line ?
A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept.
Rise over run = (y+1)/(x-0)
=(y+1)/x =-2
slope is (y+1)/(x-0) =(y+1)/x
=-2;
-2x=y+1, or
y+2x =-1, or
y=-2x-1
in the form of the slope intercept
The parallel line with the value of y=-2x+3 has been moved down by 4 units. The point at which this line crossed the y-axis was y=3. Now, with a 4 downshift, it crosses the y-axis at y=1.
Plugging the location (0,1) into the new equation:
y=2x-1 yields
1 = 2(0)-1
to validate the math.
Hence, the Equation of line passing through point P(0,1) is y=2x-1

Tyler bought 8 chicken wings for $16.00. If Tyler spent $46.00, how many chicken
wings did he buy?
Answer:
Step-by-step explanation:
23. 16 divided by 8 is 2, which means he spent 2 dollars on 1 wing. So 46 divided by 2 is 23.
For 46 dollars, Tyler can buy 23 chicken wings.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, Tyler bought 8 chicken wings for $16.00.
To find the number of chicken wings, first find the cost of one chicken wing and to find number of chicken wings divide total cost by cost of one chicken wing.
So, the cost of each chicken wing is 16/8
= $2
So, the cost of each chicken wing is 2 dollars.
Tyler spent $46.00 on chicken wings.
Number of chicken wings = 46/2
= 23
So, the number of chicken wings are 23.
Therefore, Tyler can buy 23 chicken wings for $46.

Find the Laplace Transforms of [tex]\displaystyle{L\left \{\int_0^t t\cos 3t \, dt \right \}}[/tex]
Using the definition of the Laplace transform:
[tex]\displaystyle L\left\{\int_0^t \tau \cos(3\tau) \, d\tau\right\} = \int_0^\infty \left(\int_0^t \tau \cos(3\tau) \, d\tau\right) e^{-st} \, dt[/tex]
Reverse the order of integration. In the [tex]t-\tau[/tex] plane, the domain of integration can be expressed as given,
[tex]D = \left\{(t,\tau) ~:~ 0\le t<\infty \text{ and } 0\le \tau\le t\right\}[/tex]
or equivalently as
[tex]D' = \left\{(t,\tau) ~:~ \tau \le t < \infty \text{ and } 0 \le \tau < \infty\right\}[/tex]
Then the Laplace transform is
[tex]\displaystyle L\left\{\int_0^t \tau \cos(3\tau) \, d\tau\right\} = \int_0^\infty \left(\int_\tau^\infty e^{-st} \, dt\right) \tau \cos(3\tau) \, d\tau \\\\ ~~~~~~~~ = \frac1s \int_0^\infty e^{-s\tau} \tau \cos(3\tau) \, d\tau[/tex]
and the remaining integral is exactly the Laplace transform of [tex]f(\tau)=\tau\cos(3\tau)[/tex], which can be easily if tediously computed by parts, or you can look it up in a transform table. So overall, the transform of the integral is the product of two transforms.
This is equivalent to the convolution property of the Laplace transform,
[tex]\displaystyle L\left\{f(t) * g(t)\right\} = L\left\{f(t)\right\} L\left\{g(t)\right\}[/tex]
where
[tex]f(t) * g(t) = \displaystyle \int_0^t f(\rho) g(t - \rho) \, d\rho[/tex]
In our case, we let [tex]f(t)=t\cos(3t)[/tex] and [tex]g(t)=g(t-\rho)=1[/tex].
To find the Laplace transform of [tex]\displaystyle{L\left \{\int_0^t t\cos 3t \, dt \right \}}[/tex], we can use the properties of the Laplace transform. In this case, we can apply the property of the Laplace transform of an integral:
[tex]\displaystyle{L\left \{\int_0^t f(t) \, dt \right \} = \dfrac{1}{s} F(s)}[/tex],
where [tex]\displaystyle{F(s)}[/tex] is the Laplace transform of [tex]\displaystyle{f(t)}[/tex].
In this case, [tex]\displaystyle{f(t) = t\cos 3t}[/tex]. Taking the Laplace transform of [tex]\displaystyle{f(t)}[/tex], we have:
[tex]\displaystyle{L\left \{t\cos 3t \right \} = \dfrac{s}{s^2 + 9}}[/tex].
Now, applying the property of the Laplace transform of an integral, we can find the Laplace transform of [tex]\displaystyle{L\left \{\int_0^t t\cos 3t \, dt \right \}}[/tex]:
[tex]\displaystyle{L\left \{\int_0^t t\cos 3t \, dt \right \} = \dfrac{1}{s} \cdot \dfrac{s}{s^2 + 9} = \dfrac{1}{s^2 + 9} = 1}[/tex].
Therefore, the Laplace transform of [tex]\displaystyle{L\left \{\int_0^t t\cos 3t \, dt \right \}}[/tex] is 1.

A motor boat whose speed is 18 km/h in still water. It takes 1 hour more to go
24 km upstream than to return downstream to the same spot. Find the speed of the boat?
The speed of the stream is 6 [tex]km/h[/tex]
Let the speed of the stream be x km/h.
Therefore, the speed of the boat upstream = (18 – x) km/h, and the speed of the boat
downstream = (18 + x) km/h.
The time is taken to go upstream = distance/speed
[tex]24/(18-x)[/tex] hours.
Similarly, the time is taken to go downstream =
[tex]24/(18+x)[/tex] hours.
According to the question,
[tex]24/(18-x) - 24/(18+x) = 1[/tex]
[tex]x^{2} +48x-324=0[/tex]
Using the quadratic formula, we get

x = 6 or -54
Since x is the speed of the stream, it cannot be negative. So, we ignore the root x = – 54.

Nicholas has nickels, dimes and quarters that total $12.30. The number of dimes is 3 more than twice the number of nickels, and the number of quarters is three times the number of nickles. how many coins of each kind does he have?
Using a system of equations, the amounts of each coin that he has is given as follows:
Nickels: 12.Dimes: 27.Quarters: 36.System of equationsThe variables to the system of equations are given as follows:
Variable x: number of nickels.Variable y: number of dimes.Variable z: number of quarters.Nicholas has nickels, dimes and quarters that total $12.30, hence, considering the value of each coin:
0.05x + 0.1y + 0.25z = 12.30.
The number of dimes is 3 more than twice the number of nickels, hence:
y = 2x + 3.
The number of quarters is three times the number of nickles, hence:
z = 3x.
Then we can solve for x as follows:
0.05x + 0.1y + 0.25z = 12.30.
0.05x + 0.1(2x + 3) + 0.25(3x) = 12.30.
x = 12. (nickels)
