The approximate value of s, the speed of the car in feet per second is 5.32 ft/s
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that:
tan(θ) = s² / 49
Also:
sinθ = 1/2
θ = sin⁻¹ (0.5) = 30⁰
tan(30) = s² / 49
s = 5.32 ft/s
The approximate value of s, the speed of the car in feet per second is 5.32 ft/s

Find the surface area of the prism.
7 yd
7 yd
7 yd
The surface area of the prism is 294yd²
What is surface area?The area occupied by a three-dimensional object by its outer surface is called the surface area. The prism is a square prism also called cube.
Therefore the surface area of a cube is expressed as;
SA = 6l².
This is because a cube has 6 equal faces. The area of each face is given as l². Where l is the side length.
Therefore the surface area of the prism is calculated as;
SA = 6l²
= 6 × 7²
= 6 × 49
= 294yd²
therefore the area of the prism is 294yd²

Find the value of y.
960
1660
y = [? ]°
Answer:
y = 48°
Step-by-step explanation:
The value of an inscribed angle is half the value of the arc it subtends.
The angle marked x subtends the arc marked 66°, so has a value of ...
x = 66°/2
x = 33°
The value of y is similarly found.
y = 96°/2
y = 48°
The angle marked with a dot is an external angle of the triangle, so is the sum of the remote internal angles, x and y:
dot angle = x + y = 33° +48° = 81°
Of course, angle z is the supplement of this:
z = 180° -81°
z = 99°

After spending $200 on market research, you discover that you can sell many more copies of your book if you price it at $20. Write new functions for both your expenses and your income from selling x copies.
Answer:
next time put the whole question but
a) In the cost function you have a fixed cost and a variable cost. The variable cost is the slope of the line and the fixed cost is the y-intercept so we can say:
c(x)=4x+1550
b) If you want to break even at 50 books, let p equal the price you need to charge, then we will need to create a profit function. Profit equals revenue minus cost.
r(x)=px and c(x)=4x+1550, so P(x) (P(x) is the Profit function:
P(x)=r(x)-c(x) so:
P(x)=px-4x-1550
And we wish to break even at 50 books, so P(50)=0:
50p-4(50)-1550=0
50p-1750=0
50p=1750
p=$35.00
So you must price the book at $35.00 so that you break even when you sell 50 books.
c)
The income function is just like the profit function that we found in the last problem, and if we use the price found in that equation we have:
P(x)=35x-4x-1550
P(x)=31x-1550
d)
The variable cost should be the same, the fixed cost SHOULD go up because you have spent $200.00 more for research. The cost function should now be:
c(x)=4x+200+1550
c(x)=4x+1750
But now our revenue function has changes since we are changer our price to $20 per book, And since P(x)=r(x)-c(x) we have:
P(x)=20x-4x-1750
P(x)=16x-1750

Question #5 Show steps
Correct answer is C
We need to find the derivative first. Think of x/(x+2) as x(x+2)^(-1). That will allow us to use the product rule. You could also use the quotient rule if you want. I'll go with the product rule route.
[tex]f(x) = \frac{x}{x+2}\\\\f(x) = x(x+2)^{-1}\\\\f'(x) = (x+2)^{-1}-x(x+2)^{-2}\\\\f'(x) = \frac{1}{x+2}-\frac{x}{(x+2)^2}\\\\f'(x) = \frac{x+2}{(x+2)^2}-\frac{x}{(x+2)^2}\\\\f'(x) = \frac{x+2-x}{(x+2)^2}\\\\f'(x) = \frac{2}{(x+2)^2}\\\\f'(x) = \frac{2}{x^2+4x+4}\\\\[/tex]
Since we want the tangent slope to be 1/2, we'll set f ' (x) equal to 1/2 and solve for x.
[tex]f'(x) = \frac{2}{x^2+4x+4}\\\\\frac{1}{2} = \frac{2}{x^2+4x+4}\\\\1*(x^2+4x+4) = 2*2\\\\x^2+4x+4 = 4\\\\x^2+4x = 0\\\\x(x+4) = 0\\\\x = 0 \ \text{ or } \ x+4 = 0\\\\x = 0 \ \text{ or } \ x = -4\\\\[/tex]
The two x values, x = 0 and x = -4, make f ' (x) equal to 1/2.
---------
If x = 0, then y is...
[tex]y = f(x)\\\\f(x) = \frac{x}{x+2}\\\\f(0) = \frac{0}{0+2}\\\\f(0) = 0\\\\[/tex]
Showing that (0,0) is one point we're after.
If x = -4, then,
[tex]y = f(x)\\\\f(x) = \frac{x}{x+2}\\\\f(-4) = \frac{-4}{-4+2}\\\\f(-4) = 2\\\\[/tex]
Making (-4, 2) the other point where the tangent slope is 1/2.
We use the original f(x) function, and not the derivative, when determining the y coordinates of the two points. If you plugged x = 0 or x = -4 into f ' (x), you'd get 1/2. So its good practice, but not what we're after ultimately.

Answer:
[tex]Range = \{4,7,9\}[/tex]
Step-by-step explanation:
Given
The attached function
Required
The range of the function
A function is represented by matching an arrow from the domain to the range.
This implies that, the arrow comes from the domain to the range
From the attached function, the arrow points to 4,7 and 9
Hence, the range is:
[tex]Range = \{4,7,9\}[/tex]
3. Which two expressions are equivalent for any value of y? *
O A. 3(3y + 3) and 6y + 6
B. 3(3y + 3) and 9y + 6
O c. 9(y + 3) and 12 + 9y
O D. 9(y + 3) and 27 + 9y
Given:
The pair of expressions in the options.
To find:
The two expressions are equivalent for any value of y.
Solution:
Two expressions are equivalent for any value of y, iff they are equivalent.
[tex]3(3y+3)=3(3y)+3(3)[/tex]
[tex]3(3y+3)=9y+9[/tex]
Clearly, [tex]3(3y+3)[/tex] is not equivalent to [tex]6y+6[/tex] or [tex]9y+6[/tex]. So, options A and B are incorrect.
[tex]9(y+3)=9(y)+9(3)[/tex]
[tex]9(y+3)=9y+27[/tex]
[tex]9(y+3)=27+9y[/tex]
The expression [tex]9(y+3)[/tex] is not equivalent to [tex]12+9y[/tex]. So, option C is incorrect.
The expression [tex]9(y+3)[/tex] is equivalent to [tex]27+9y[/tex].
Therefore, the correct option is D.

Only serious answers plzzzzz
Answer:
x = 9
Step-by-step explanation:
4(5 + 4) = 3(x + 3) => Intersecting secants theorem
4(9) = 3(x + 3)
Open bracket by applying distributive property
36 = 3x + 9
Subtract 9 from each side
36 - 9 = 3x + 9 - 9
27 = 3x
Divide both sides by 3
27/3 = 3x/3
9 = x
x = 9

A potteruses clayat a daily rate that is normally distributed with a mean of 27pounds and a standard deviation of 8pounds. When the potterplaces an order for the clayit requires 5days for the order to arrive.7.What is the Service Level if the shop places an order when inventory reaches 155pounds
Answer:
100 percent
Step-by-step explanation:
mean ( average daily demand ) ( d ) = 27 pounds
standard deviation of demand ( std ) = 8 pounds
Lead time ( taken order takes to arrive ) ( L ) = 5 days
Reorder point = 155 pounds
Determine the service level )
Applying the equation below
Reorder point = d x L + (Z x std ) note : Z = service factor
155 = 27 * 5 + ( Z * 8 )
155 = 135 + 8Z
hence Z ( service factor ) = ( 155 - 135 ) / 8 = 2.5
hence the service level is ≈ 100 percent
