The length of actual car is 13.5 feet
We are given the ratio, which will be interpreted as 1 inch of model will be equal to 18 inch of the real car.
So, the formula relating the scale length and actual length will be as follows -
Scale = Real
Model length at scale/Actual length at scale = Model length in real/Actual length in real
Keep the values in formula to find the actual length of car
1/18 = 9/Actual length of car in real
Actual length of car in real = 9 × 18
Performing multiplication
Actual length of car in real = 162 inches
Converting length from inches to feet -
1 inch = 0.0833 feet
162 inch = 0.0833×12
162 feet = 13.5 feet
Hence, the actual length of car in real is 13.5 feet

Graph the function f(x) = x3 – 10x2 + 28x – 24 Then, write a

- Type of polynomial function and degree
- Domain & Range
- End behavior
- Intervals of Increasing/Decreasing
- Intervals of Positive/Negative
- Turning points (including whether it's a relative max or relative min)
- Zeros and their multiplicity (and the effect of the multiplicity on the graph)
- Cubic Function | 3-degree
- Domain & Range | Domain and Range both are all set of Real Numbers.
- End Behavior | When x approaches positive infinity, f(x) approaches positive infinity as well. When x approaches negative infinity, f(x) approaches negative infinity too.
- Intervals of Increasing/Decreasing | Increases at (-∞, 2) U (6,∞) and Decreases at (2,14/3) aka 2 < x < 14/3
- Intervals of Positive/Negative
Positive when x > 6 or (6,+∞)
Negative when 2 < x < 6 and x < 2 or (2,6) U (-∞,2)
- Turning Points are (2,0) and (14/3, -256/27)
- Zeros and Multiplicity | Factoring the polynomial as we get (x-2)(x-2)(x-6). Therefore, the zeros are multiplication of 2 and 6.
Multiplicity will affect the graph for x-axis. When the multiplicity kicks in, the graph will turn either decreasing on increasing on x-axis immediately.

There are 12800 films on Netflix. 9% of the films are horror. How many films are horror?
Answer:
1152
Step-by-step explanation:
You multiply the 12800 films by 9% to get your answer.
Answer:
1152
Step-by-step explanation:
Step 1: Our output value is 9.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$9=100\%$.
Step 4: Similarly, $x=12800\%$.
Step 5: This results in a pair of simple equations:
$9=100\%(1)$.
$x=12800\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{9}{x}=\frac{100\%}{12800\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{9}=\frac{12800}{100}$
$\Rightarrow x=1152$
Therefore, $12800\%$ of $9$ is $1152$
this took a really long time

The perimeter of the given rectangle is, 19.2112
Given that, the vertices of the rectangle are A(-3,-2), B(-5,-5), C(1,-5), D(3,-2) .
to find the perimeter through the given vertices, we need to calculate the distance from the vertices AB,BC,CD,DA.
we already know that the sum of all sides of the rectangle is known as the perimeter of the rectangle.
Using distance formula between 2 vertices , √[(x2-x1)²+(y2-y1)²]
AB = √[(-5+3)²+(-5+2)²]
= √[(-2)²+(-3)²]
= √[4+9]
= √[13]
= √13
AB = 3.6056
BC = √[(1+5)²+(-5+5)²]
= √[(6)²+(0)²]
= √[36+0]
= √[36]
= √36
BC = 6
CD = √[(3-1)²+(-2+5)²]
= √[(2)²+(3)²]
= √[4+9]
= √[13]
= √13
CD = 3.6056
DA = √[(-3-3)²+(-2+2)²]
= √[(-6)²+(0)²]
= √[36+0]
= √[36]
= √36
DA = 6
Therefore perimeter of the rectangle with given vertices is ,
= AB+BC+CD+DA
= 3.6056+6+3.6056+6
= 19.2112
= 19 (rounded to nearest tenth).
Therefore the perimeter of the rectangle with given vertices is 19.2112

A school paid $248 for new basketballs and soccer balls. The number of basketballs purchased was 6 less than 3 times the number of soccer balls purchased. Basketballs cost $28 each and soccer balls cost $20 each. How many total balls did the school purchase?
Answer:
4 Soccer balls and 6 Basketballs
Step-by-step explanation:
You can solve this problem by setting up a system of equations. Letting x be Soccer balls and y be Basketballs. Remember, Money goes with, Money goes with Money, meaning that for this problem the first equation that can be made is $248 = $28y + $20x with Y being basketballs and x being soccerballs. Next is a little more difficult. You will be creating the equation y=3x-6 because it is 6 less than 3 times the amount of x or Soccer balls. From here you can plug in the equations into a graphing calculator and graph it and see where the two lines intersect. This would be at (4, 6). When I said to let x equal Soccer Balls and y equal basketballs that is where I got the 4 soccer balls and 6 basketballs.

How can you determine the sale price if you are given the regular price and the percent of markdown? (List the steps)
Answer:
The sale price is $34
Step-by-step explanation:
If we are given the regular price P and the markdown percentage r, we follow these steps:
1) Calculate the markdown or discount amount M.
M = P*r/100
2) Subtract it from the regular price:
S = P - M
S is the sale price.
Example: The regular price is $40 and the markdown percentage is 15%. Thus:
1) M = $40*15/100 = $6
2) S = $40 - $6 = $34
The sale price is $34

What is the factorization of 2x + 5x + 3?
Answer:
(2x+3)(x+1)
Step-by-step explanation:
A P E X
The factorization of the polynomial 2x² + 5x + 3 is (2x + 3)(x + 1).
What is Polynomial?Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables
To factorize 2x² + 5x + 3, we need to find two binomials in the form of (ax + b) and (cx + d) such that their product equals the given expression.
Firstly Multiply the coefficient of the first term (2) by the constant term (3) to get 6.
The two factors of 6 that add up to the coefficient of the middle term (5). In this case, the factors are 2 and 3.
Now Rewrite the middle term using the two factors found in the previous step. We have:
2x² + 2x + 3x + 3
We can factorize the first two terms by taking out 2x as a common factor and the last two terms by taking out 3 as a common factor. We get:
2x(x + 1) + 3(x + 1)
(2x + 3)(x + 1)
Therefore, the factorization of 2x² + 5x + 3 is (2x + 3)(x + 1).

=======================================================
Explanation:
The information that m || n is not needed or used, so I'm not sure why your teacher put that in there.
The angles shown are a linear pair. They are adjacent and they are supplementary. They form a straight angle.
Supplementary angles add to 180.
(x-17)+(5x-1) = 180
x-17+5x-1 = 180
(x+5x)+(-17-1) = 180
6x-18 = 180
6x = 180+18
6x = 198
x = 198/6
x = 33
---------
Extra info:
if x = 33, then,
x-17 = 33-17 = 165x-1 = 5*33-1 = 165-1 = 164Adding the angles gives 16+164 = 180 which helps confirm our answer.

Answer:
You need to invest at a continuous compound interest rate of 6.701355026%
Step-by-step explanation:
The formula to use is the compound interest formula:A=P(1+r/100)^t
where A=Total amount at the end of the investment period
P=Principal amount
R=Rate of interest
T=Investment tenor/time
