Given f of x equals 5 times x minus 6 for x less than 3, equals x squared for x between 3 and 5 inclusive, and equals 2 times x plus 15 for x greater than 5 find f '(x) and give its domain.
Answer:
D. 5 for x less than or equal to 4, equals 2x for x between 4 and 6 including 6, and equals 4 for x greater than 6 Domain: All real numbers.
Step-by-step explanation:
Find the complete diagram attached
First we need to get the derivative of the functions
For the function f(x) = 5x - 6
Using the formula
If f(x) = axⁿ
f'(x) = naxⁿ⁻¹
For the function f(x) = 5x - 6
f'(x) = 1(5)x¹⁻¹
f'(x) = 5x⁰
f'(x) = 5
For the function f(x) =x²-2
f'(x) = 2x²⁻¹
f'(x) = 2x
For the function f(x) = 4x+10
f'(x) = 1(4)x¹⁻¹
f'(x) = 4x⁰
f'(x) = 4
Get the domain
The domain is the value of the input variable x for which the functions exists. For the functions given, the domain will be on all real numbers i.e the functions will exists for any value of x on the number line.

Answer:
A)20°
Step-by-step explanation:
As we know a triangle contains 180°
So according to the question
The equation is
25°+135°+x=180°
160°+x=180°
x=180°-160°
x=20°
Answer:
<LNK = 20°
Step-by-step explanation:
[tex]angles \: of \: triangle \: add \: upto \: {180}^{0} \\ in \: that \: scalene \: triangle \\ {25}^{0} + {135}^{0} + < lnk = {180}^{0} \\ < lnk = {180}^{0} - ( {135}^{0} + {25}^{0} ) \\ < lnk = {20}^{0} [/tex]
The first company charges $3.50 per cubic foot of rock and $80 for delivery. The second company charges $2.50 per cubic foot of rock and $120 for delivery. Which system of equations can be used to determine the value of the width, x, at which the cost of the two companies, y, is the same?
Answer:
x = 40
Step-by-step explanation:
First company:
Charges = per cubic foot of rock fee + delivery fee
y = $3.50x + $80
Second company:
Charges = per cubic foot of rock fee + delivery fee
y = $2.50x + $120
Equate the charges of both companies
$3.50x + $80 = $2.50x + $120
3.50x - 2.50x = 120 - 80
x = 40
The cost of the two companies, y are equal when x = 40

4) Write the quadratic equation of the following in vertex form: vertex (-1,3) and passes through (1, -5)
3. Graph the given quadratic function in the factored form as shown below.
4. The quadratic equation in vertex form, given the vertex (-1,3) and passes through (1, -5), is y = -2(x + 1)² + 3.
The given quadratic function in factored form is y = (x - 3)(x + 1).
Graph of the given quadratic function in the factored form as shown below.
Zeros: The zeros of the function occur when y = 0.
So the zeros of the function are x = 3 and x = -1.
Axis of Symmetry:
The axis of symmetry is x = (3 + (-1)) / 2 = 1.
Vertex:
The vertex is (1, -4).
Y-intercept:
The y-intercept is (0, -3).
Domain: The domain of a quadratic function is all real numbers, so the domain is (-∞, ∞).
Range: Since the coefficient of the x² term is positive, the parabola opens upward. Therefore, the range is y ≥ -4.
Write the quadratic equation of the following in vertex form: vertex (-1,3) and passes through (1, -5)
Using the given information, the vertex form equation can be written as:
[tex]y = a(x - (-1))^2 + 3[/tex]
To find the value of 'a,' we can substitute the coordinates (1, -5) into the equation:
-5 = a(1 - (-1))² + 3
-5 = a(2)² + 3
-5 = 4a + 3
-8 = 4a
a = -2
Plugging the value of 'a' back into the equation, we get the quadratic equation in vertex form:
y = -2(x + 1)² + 3
Therefore, the quadratic equation in vertex form, given the vertex (-1,3) and passes through (1, -5), is y = -2(x + 1)² + 3.

How would you solve a linear equation with X and Y on the same side
Either the question is printed wrong..
Or the answer should simply be
3x + 4y = 10
Answer:
see explanation
Step-by-step explanation:
To solve, choose a value of x or y, substitute into the equation and evaluate for the other variable.
Choose x = 2, then
3(2) + 4y = 10
6 + 4y = 10 ( subtract 6 from both sides )
4y = 4 ( divide both sides by 4 )
y = 1
Thus (2, 1 ) is a solution to the equation
A school club wants to collect at least 500 canned goods for a school food drive. The club has already collected 30 canned goods
Part A
If 10 club members each collect the same number of canned goods, which inequality represents the minimum number of canned goods, n, each club
member must select for the club to meet the goals?
Answer:
The correct answer is 10n ≥ 470.
Step-by-step explanation:
Since, the school club wants to collect at least 500 canned goods, then we know that they don't want to collect any less: they must collet 500 or more canned goods.
They already collected 30 canned goods, therefore we can subtract this quantity from out goal.
500 - 30 = 470
Since there are 10 club members, the number of members multiplied by "n" the minimum amount of canned goods that they can collect, will equal the total amount of canned goods that they need.

Determine whether the triangles are similar. If similar, state how (AA, SSS, or SAS), and write a similarity statement.
Answer: The triangles are not similar.
===============================================
Explanation:
Create a 3x3 table. It has 3 rows and 3 columns.
Above the top row, we'll have the side lengths of triangle VUW
Along the left side of the table, we'll have the lengths of triangle LNM
Refer to the diagram below to see what I mean. I used a spreadsheet program to create the table.
Once you have those table headers set up, you'll divide each possible pair of side lengths between the two triangles. For example, VU/LN = 35/20 = 1.75 which is represented as the green cell in the upper left corner (row1,column1). The other 8 green table cells are filled out the same way. This table is a handy way to keep track of all the terms since it's easy to lose track. Again, refer to the diagram below.
After the table is filled out, we need to ask ourselves: "Does a certain value show up 3 times in the green cells?". If so, then we could have similar triangles assuming this value shows up in every row and every column in some fashion.
Unfortunately, we don't have a value show up 3 times in the green cells. The values 1.4 and 1.75 come close by showing up twice, but not three times.
Since we don't have a value show up 3 times, this means that the sides are not proportional to one another. Therefore, the triangles are not similar.

I have a half-full bottle of water and it has more than 8 ounces in it. What would be the expression
Answer:
The equivalent expression is [tex]\frac{1}{2}\cdot V_{max} > 8\,oz[/tex].
Step-by-step explanation:
The best approach consists in translating the sentence given in the question into mathematical terms until an expression is complete:
(i) I have a half-full bottle of water
Translation: I use a bottle with a maximum volume capacity [tex]V_{max}[/tex], measured in ounces, a half of it is full of water:
[tex]\frac{1}{2}\cdot V_{max}[/tex]
(ii) And it has more than 8 ounces in it
Translation: The volume occupied by the water is greater than 8 ounces. Hence, we get the following inequation:
[tex]\frac{1}{2}\cdot V_{max} > 8\,oz[/tex]

Answer:
3 hours
Step-by-step explanation:
If both the cars are moving in the same direction,
Speed of orange sports car = 60 miles per hour
Since, this car has already moved for 1 hour,
Distance covered by the sports car = speed × time
= 60 × 1
= 60 miles
Speed of the green van = 30 miles per hour
Since, green van has already moved for the duration = 3 hours
Distance covered by the green van = speed × time
= 40 × 3
= 120 miles
Therefore, distance between sports car and green van = 120 - 60
= 60 miles
Relative speed of orange sports car with respect to green van = Speed of sports car - speed of green van
= 60 - 40
= 20 miles per hour
Time taken by the orange sports car to cover 60 miles (Distance between sports car and green van) = [tex]\frac{\text{Distance between the car and van}}{\text{Relative speed of the sports car}}[/tex]
= [tex]\frac{60}{20}[/tex]
= 3 hours
Therefore, orange sports car will take 3 hours to pass the green mini green van.
