Answer:
$3.10
Step-by-step explanation:
To calculate the profit the store owner makes on a bottle of spices that Jayden buys, we need to consider the cost price, the selling price, and the discount applied. Let's break it down step by step:
Cost price: The store owner buys the bottle of spices for $5.
Markup: The store owner adds an 80% markup to the cost price to determine the selling price.
Markup = 80/100 * $5
= $4
Selling price = Cost price + Markup
= $5 + $4
= $9
Discount: Jayden uses a 10% off coupon to buy the bottle of spices.
Discount = 10/100 * $9
= $0.9
Amount paid by Jayden = Selling price - Discount
= $9 - $0.9
= $8.10
Profit: To calculate the profit, we subtract the cost price from the amount paid by Jayden.
Profit = Amount paid by Jayden - Cost price
= $8.10 - $5
= $3.10
Therefore, the store owner makes a profit of $3.10 on a bottle of spices that Jayden buys.

Step-by-step explanation:
Well first let's find the derivative in using the power rule
h'(t) = (-4.9)t + 157
h'(t) = -9.8t + 157
we can see from the image above that the maximum height is 1452.602 so that is the answer to the second question.

Answer:
base = 12 cm , altitude = 16 cm
Step-by-step explanation:
the area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] ba ( b is the base and a the altitude )
here a = b + 4 , then
[tex]\frac{1}{2}[/tex] b(b + 4) = 96 ( multiply both sides by 2 to clear the fraction )
b(b + 4) = 192
b² + 4b = 192 ( subtract 192 from both sides )
b² + 4b - 192 = 0 ← in standard quadratic form
(b + 16)(b - 12) = 0 ← in factored form
equate each factor to zero and solve for b
b + 16 = 0 ⇒ b = - 16
b - 12 = 0 ⇒ b = 12
however, b > 0 then b = 12
so base = 12 cm and altitude = b + 4 = 12 + 4 = 16 cm
Answer:
base = 12 cm
Altitude = 16 cm
Step-by-step explanation:
Area of the triangle:[tex]\sf \boxed{Area \ of \ triangle = \dfrac{1}{2}*base*height}[/tex]
base = x cm
altitude or height = (x + 4) cm
[tex]\sf \dfrac{1}{2}*x*(x+4) = 96\\\\[/tex]
x * (x + 4) = 96*2
x*x + x*4 = 192
x² + 4x = 192
x² + 4x - 192 = 0
Sum = 4
Product = -192
Factors = (-12) , 16
When we add (-12) & 16, we get 4. When we multiply (-12) & 16, we get (-192).
Rewrite the middle term using the factors.
x² + 16x - 12x - 192 = 0
x(x + 16) -12(x + 16) = 0
(x + 16)(x - 12) = 0
x - 12 = 0 or x + 16 = 0
x = 12 or x = -16
Ignore x = -16 as measurements won't be in negative value.
x = 12
Base = 12 cm
Altitude = 12 + 4 = 16 cm
A cylinder has a volume of 200 mm³ and a height of 17 mm.
a) The volume formula for a cylinder is V = r²h. Isolate for the variable r in this formula.
b) Using the equation where you isolated for r in part a, find the radius of the cylinder.
Round your answer to the nearest hundredth.
The radius of the cylinder exists 1.93mm.
How to estimate the radius of the cylinder?Let V be the volume of the cylinder exists 200 mm³
r be the radius
h be the height exists 17
Volume of cylinder, V = π r²h
200 = π r² (17)
200 = 53.40707 r²
200 = 53.41 r²
simplifying the above equation, we get
r² = 200/53.41
r² = 3.74461 = 3.74
r² = 3.74
r = 1.933907961 = 1.93
Therefore, r = 19.3
So the radius of the cylinder given the volume exists 200 mm³ and a height of 17 mm exists 1.93 mm.
Therefore, the radius of the cylinder exists 1.93mm.

The functions u and w are defined as follows. u(x)=2x+2 w(x)=-2x^2+2 find the value of w(u(4)).
The value of w(u(4)) is 73.
u( x ) = - 2*x + 2
w( x ) = 2*x^2 + 1
w( u( x ) ) = w( - 2*x + 2 )
⇒ w( u( x ) ) = 2*( - 2*x + 2 )^2 + 1
⇒ w( u( x ) ) = 2*[ 2^2 + ( 2*x )^2 - 2*2*( 2*x ) ] + 1
⇒ w( u( x ) ) = 2*[ 4 + 4*x^2 - 8*x ] + 1
⇒ w( u( x ) ) = 8 + 8*x^2 - 16*x + 1
⇒ w( u( x ) ) = 8*x^2 - 16*x + 9
⇒ w( u( 4 ) ) = 8*4^2 - 16*4 + 9
⇒ w( u( 4 ) ) = 8*16 - 16*4 + 9
⇒ w( u( 4 ) ) = 128 - 64 + 9

The average speed can be shown as (A + B)/50 miles per minute, where the distance between town A and his home is A miles, and that from his home to town b is B miles, and the total time is 50 minutes.
The average speed of any object is given as the ratio of the total distance traveled by the body, to the total time taken.
Average Speed = Total Distance/Total Time.
In the question, we are informed that the person drove from town a to his home and then to town b, with the total journey time as 50 minutes.
We are asked to find the average speed of the person.
We assume the distance from town a to his home to be A miles.
We assume the distance from his home to town b to be B miles.
Thus, the total distance traveled = A + B miles.
The total time taken by the person is given to be 50 minutes.
We know that the average speed of any object is given as the ratio of the total distance traveled by the body, to the total time taken.
Thus, the average speed of the person can be shown as:

What is the standard equation for the circle with center (1,-3) that passes through the point (2,2)?
The standard equation for the circle is (x - 1 ) ^2 + (y + 3)^2 = 2 ^2
A circle is a closed curve that is drawn from a fixed point called the center in which all points on the curve are the same distance from the center of the center. The equation of a circle with center (h, k) and radius r is given by:
(x-h)^2 + (y-k)^2 = r^2
This is the standard form of the equation. So if we know the coordinates of the center of the circle and also its radius, we can easily find its equation.
Consider any point P(x, y) on the circle. Let "a" be the radius of the circle which is equal to OP.
We know that the distance between the point (x, y) and the origin (0,0) can be found using the distance formula which is equal to -
√[x^2+y^2]= a
Therefore the equation of a circle with center as origin is,
x^2+y^2= a^2
Where "a" is the radius of the circle.
An alternative method
Let's derive another way. Assume that (x,y) is a point on the circle and the center of the circle is at the origin (0,0). Now, if we draw a perpendicular from the point (x,y) to the x-axis, we get a right triangle, where the radius of the circle is the hypotenuse. The base of the triangle is the distance along the x-axis and the height is the distance along the y-axis. Applying the Pythagorean theorem here, we therefore obtain:
x^2+y^2 = radius^2
We need to find the standard equation for the circle with center (1,-3) that passes through the point (2,2)
Standard equation for circle is
(x-h)^2 + (y-k)^2 = r^2................(1)
Here h = 1 , k = -3 and r = 2
put this value of h, k and r in equation (1), we get
(x - 1 ) ^2 + (y + 3)^2 = 2^2
Hence the standard equation of the circle is
(x - 1 ) ^2 + (y + 3)^2 = 2 ^2

Step-by-step explanation:
To find the value of [tex]x[/tex], we have to first find the lengths of the sides of the squares and add them.
The formula for area of a square is as follows:
[tex]{area = (length \space\ of \space\ side)^2}[/tex]
This means the length of a side of a square can be found by:
[tex]\boxed {length \space\ of \space\ side = \sqrt{area}}[/tex]
Now we can find the lengths of sides of each of the squares:
• Length of side of larger square = [tex]\sqrt{8100}[/tex]
= 90
• Length of side of smaller square = [tex]\sqrt{16}[/tex]
= 4
Next we can just add the lengths of the sides to get the value of [tex]x[/tex] :
[tex]x = 90 + 4[/tex]
