Step-by-step explanation:
The distance formula is:
[tex]d = \sqrt {\left( {x_2 - x_1} \right)^2 + \left( {y_2 - y_1} \right)^2 }[/tex]
We can plug in the given coordinates into the equation:
[tex]d = \sqrt {\left( {4 - 9} \right)^2 + \left( {-3 - (-3)} \right)^2 }\\d = \sqrt {\left( {-5} \right)^2 + \left( {-3+3} \right)^2 }\\d = \sqrt{25 + \left( {0} \right)^2 }\\d=\sqrt{25+0}\\d=\sqrt{25}\\d=5[/tex]

B. X^5-3
C. 9x^5-27x
D. X^4-3
E.x^5-3x
F. X^4-3x
Answer:
x⁴-3
Step-by-step explanation:

Given the functions k(x) = 2x2 − 7 and p(x) = x − 4, find (k ∘ p)(x). (k ∘ p)(x) = 2x2 − 8x 16 (k ∘ p)(x) = 2x2 − 16x 32 (k ∘ p)(x) = 2x2 − 16x 25 (k ∘ p)(x) = 2x2 − 11.
Function represents a relationship between variables. The product of the two given functions (k·p)(x) is 2x³-8x²-7x+28.
What is Function?A function assigns the value of each element of one set to the other specific element of another set.
Given to us
k(x) = 2x² − 7
p(x) = x − 4
As the two equations are given to us, k(x) and p(x), and we need to find (k ∘ p)(x), And we know the product of two functions can be written as,
[tex](k \cdot p)(x) = k(x) \cdot p(x)[/tex]
therefore,
[tex]k(x) \cdot p(x)\\\\= (2x^2-7)(x -4)\\\\= 2x^3 - 8x^2 - 7x +28[/tex]
Hence, the product of the two given functions (k·p)(x) is 2x³-8x²-7x+28.

Step-by-step explanation:
This is percentage increase and its calculated with the formula:
C2 = x2 - x1 x 100
x1 1
where x2 = final value (75 inches)
x1 = initial value (48 inches)
c2 = relative value
pecentage increase = 100
so we say, 75 - 48 x 100

if you noticed I multiplied the second equation all through by minus so the positive 9 turned negative when multiplied by minus so negative 14 + negative 9 gives negative 23
Step-by-step explanation:
32-2y=22
y=5 because 32 minus 10 is 22 and 2y is 10
7x + 3y= 105

Consider the graph of function g.
If f(x) = x2, which equation represents function g?
A. g(x)=f(2x)
B. g(x)=f(4x)
C. g(x)=2f(x)
D. g(x)=f(1/2x)
Answer:
FOR PLATO USERS
The answer is D. g(x) = f(1/2x)
Step-by-step explanation:
A graph with f(x) = x^2 starts at point zero, just like the picture shown below, so we can only predict that the new function was stretched horizontally. The parent function, f(x) = x^2, has the following points
[tex]\left[\begin{array}{ccc}x&&y\\1&&1\\2&&4\end{array}\right][/tex]
terrible table i know (pretend its a table chart) but these are the points of a normal f(x) graph. The points of the NEW graph is:
[tex]\left[\begin{array}{ccc}x&&y\\2&&1\\4&&4\end{array}\right][/tex]
It appears that the x values in the parent function table are half of the x values in the new graph table. So, the new function would be
[tex]g(x)=f(\frac{1}{2} x)[/tex]

Answer:
[tex]\sqrt{51}[/tex] or 7.14
Step-by-step explanation:
Using the Pythagoras theorem, we can conclude the formula that we are going to use here is [tex]a^{2}+b^{2} = c^{2}[/tex]
As we can see, this is a right triangle given that it has the square in the corner there. With this information, we can conclude that the longest side is 10, making it the hypotenuse or [tex]c[/tex]
Now we need to find [tex]b[/tex] in the formula of [tex]a^{2}+b^{2} = c^{2}[/tex] making the equation [tex]b^{2} = c^{2} - a^{2}[/tex] or [tex]b = \sqrt{ c^{2} - a^{2}}[/tex]
Given the provided information, this would be [tex]b^{2} = 10^{2} - 7^{2}[/tex] or [tex]b = \sqrt{ 10^{2} - 7^{2}}[/tex]
Simplifying it would be [tex]b = \sqrt{ 100-49[/tex] = [tex]\sqrt{51}[/tex]
The radical form would be [tex]\sqrt{51}[/tex]
While it's integer would be 7.14
Hope this helps!
Answer:
Step-by-step explanation:
Use Pythagorean theorem,
Let the third side =x
base² + altitude² = hypotenuse²
7² + x² = 10²
49 + x² = 100
x² = 100 - 49
x² = 51
x = √51

Step-by-step explanation:
The area of the lawn is a trapezoid.
Area of a trapezoid = [tex]\dfrac12(a+b)h[/tex]
where a and b are the parallel sides (bases) and h is the height
Therefore,

Luna drew a scale drawing of the high school. The parking lot, which is 54 meters wide in real life, is 102 centimeters wide in the drawing. What scale did Luna use? 17 centimeters:___meters
Scale drawings are used to draw shapes in a different proportional size
The scale used in the drawing is 17 centimeters : 9 meters
How to determine the scale of the drawingFrom the question, we have:
Real length = 54 metersScale length = 102 centimetersSo, the scale is:
Scale = Scale length : Real length
This gives
Scale = 102 centimeters : 54 meters
Reduce the scale
Scale = 17 centimeters : 9 meters
Hence, the scale used in the drawing is 17 centimeters : 9 meters

case A) If the price is marked down by percent, the new price will be
we know that
If the price is marked down by 10 percent
then the new price will be
10%= 10/100=0.10
(1 - 0.10) *$28= 0.90 * $28
=$25.20
therefore The statement case A) is True
case B) If the price is marked down by 25 percent, the new price will be $21
we know that
If the price is marked down by 25 percent
then the new price will be
25%=25/100=0.25

Grace biked for 8 miles in 1 hour on Monday. She covered 18 miles in 2 hours the next day. On which day did Grace bike at a faster pace?
Solution:
Note that:
[tex]Speed = \frac{Distance}{Time}[/tex]Find the speed of her bike of both the days and compare.
Speed on Monday = 8 miles/1 hour = 8 m/hSpeed on the next day = 18 miles/2 hours = 9 m/hThis means that:
=> 9 m/h > 8 m/hHence, the day after Monday is the day, she rode her bike faster than on Monday.
Answer:
The next day
Step-by-step explanation:
she covered 8 miles in 1 hour on Monday but on tuesday she covered 9 miles in 1 hour so she biked faster the next day.

Answer: 9
Step-by-step explanation: Root 18 can be broken down into root ( 9 times 2). 9 is a square root & can be taken out as its root. Root 18 equals 3 times root 2. Multiple both 12/root & 3 root 2 by root 2. Leaves 12 + 3 times 2 or 18. Now gotta take that root 2 we multiplied by back out. Break 18 into its parts, 9 times 2. Divide the 2 by root 2, gives you root 2. So 9 times root 2. Don't have to divide 9 as well, because they all the same type of operation, multiplication/division, no adding.
