given f(x)=x^3+x^2-x what is f(4)
Answer:
76
Step-by-step explanation:
Plug 4 in for each x
Answer:
76
Step-by-step explanation:
given f(x)=x^3+x^2-x what is f(4)
whenever u see f(4) it is telling you that whenever you see an x you would replace it with a 4 so you start substituting the x for 4's or replacing them (same thing XD) 4^3+4^2-4 4 times 4 times 4 = 64 + 4 times 4 = 16
64 + 16 - 4 = 76
Ernesto baked 3 cakes in 2 1/2 hours. Assume that the number of cakes baked varies directly with the number of hours. Write and solve a direct variation equation to find how many cakes can he bake in 7 1/2 hours.
Answer: We assume that the number of cakes baked varies directly with the number of hours. Hence, he can bake 9 cakes in 7.5 hours.

Suppose m is the line with equation x=-5, line n is the equation y=1
Here is the complete question:
suppose m is the line with equation x=-5, line n is the line with equation y=1, line g is the line with equation y=x, and line h is the line with equation y=-2. Given A(9,-3), B(6,4), and C(-1,-5), what are the coordinates of the vertices of △A′B′C′ for each reflection?
1. Rx-axis
2. Ry-axis
Answer with step-by-step explanation:
1. When you get the reflecting coordinates along x-axis, the signs of the y coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:
A(9, 3), B(6, -4), and C(-1, 5).
2. When you get the reflecting coordinates along y-axis, the signs of the x coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:
A(-9, -3), B(-6, 4), and C(1, -5).

the length of a rectangular yard is 4 feet more than the width. the perimeter of the yard is 208 feet. write the equation that represents the perimeter of the yard. let w represent the width. solve the equation. what are the dimensions of the yard?
Answer:
Length = 54 ft.
Width = 50 ft.
Step-by-step explanation:
Let the width of the rectangle be 'w'.
According to question ,
Length = w + 4
Perimeter = 208 ft.
We know that [tex]perimeter = 2(l + w)[/tex] where l = length & w = width
So,
[tex]2(w + 4 + w) = 208[/tex]
[tex] = > 2(2w + 4) = 208[/tex]
[tex] = > 2w + 4 = \frac{208}{2} = 104 [/tex]
[tex] = > 2w = 104 - 4 = 100[/tex]
[tex] = > w = \frac{100}{2} = 50[/tex]
Width = 50 ft.
=> Length = 50 + 4 = 54 ft.
A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out what price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit.
y=-15x^2+801x-5900
Answer:
The widgets should be sold for $26.7 for the company to make the maximum profit.
Step-by-step explanation:
Given the quadratic equation
[tex]f\left(x\right)=-15x^2+801x-59000[/tex]
As the leading coefficient is (-3), so the graph would be a downward Parabola.
Thus, the maximum profit would be at the vertex.
The selling price 'x' can be determined by determining the x-coordinate of the vertex.
In order to calculate the x-coordinate of the vertex, we can find this by
x = -b/2a
where a = -15 and b = 801
x = -801 / 2(-15)
x = -801/-30
x = 801/30
x = 267/10
x = 26.7
Therefore, the widgets should be sold for $26.7 for the company to make the maximum profit.
In a series of 4 one day cricket matches, the runs scored by Pakistan and Australia are given below: (06 Marks) Match Pakistan Australia First 102 208 Second 202 192 Third 360 241 Fourth 276 203 Find: (i) What is the average score of Pakistan in one match? (ii) What is the average score of Australia in one match? (iii) Which team performed better?
Step-by-step explanation:
Scores of Australia in all four matches starting from 1st 208, 192, 241, 203 respectively.
Similarly, scores of Pakistan in all four matches starting from 1st 102, 202, 360, 276 respectively.
The avg of Pakistan in one match = (102+202+360+276)/4 = 235
The avg of Australia in one match = (208+192+241+203)/4= 211
Since, the avg score of Pakistan is more than that of Australia, Pakistan performed better.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 95 miles per hour. The westbound train travels at 115 miles per hour. How long will it take for the two trains to be 336 miles apart? Do not do any rounding.
Answer:
It will take 1.6 hours for the two trains to be 336 miles apart.
Step by step explanation:
Given that:
Speed of eastbound train = 95 miles per hour
Speed of westbound train = 115 miles per hour
Combined speed = 95+115 = 210 miles
Distance = 336 miles
[tex]Speed = \frac{Distance}{Time}\\\\210 = \frac{336}{Time}\\\\Time = \frac{336}{210}\\\\Time = 1.6\ hours[/tex]
Hence,
It will take 1.6 hours for the two trains to be 336 miles apart.

The graph shows the distance Kerri drives on a trip. What is Kerri's speed?
Driving Time and Distance
A. 25 miles per hour
B. 60 miles per hour
C. 75 miles per hour
D. 50 miles per hour
Answer:
Kerri's speed = 50 mile per hour. Therefore option (D) is true.
Step-by-step explanation:
Given the distance-time graph
It is clear from the distance-time graph that:
at Time = 1 hour, Distance = 50 milesat Time = 2 hours, Distance = 100 milesso the two points on the distance-time graph is:
(1, 50)(2, 100)Finding the slope between the points to determine the speed.
Please note that the slope between the points represents the speed or rate of change.
Speed = Rate of change = y₂-y₁ / x₂-x₁
= 100 - 50 / 2-1
= 50 / 1
= 50 miles per hour
Thus, Kerri's speed = 50 mile per hour. Therefore option (D) is true.
If (3 , 2) is a point on the line whose equation is y = 3x + k, determine the value of k.

5 5
The prime factorization of 100 is 2 * 2 * 5 * 5, or 2^2 * 5^2, or 5^2 * 2^2
Step-by-step explanation:
2^2 × 5^2 =
(2×2) × (5×5) =
4 × 25 = 100
5^2 × 2^2 =
(5×5) × (2×2) =
25 × 4 = 100
2*2*5*5=100
2 and 5 are the only prime numbers in this question. 2(2)*5(5) doesnt equal 100.

This recipe makes 8 portions of porridge. Complete the amount of each ingredient that is needed to make just 5 portions. Recipe: Serves 8 400 g oats 1.2 l milk 40 g sugar
Answer:
5 portions of porridge requires
250g of oats, 0.75L of milk and 25g of sugar
Step-by-step explanation:
This recipe makes 8 portions of porridge. Complete the amount of each ingredient that is needed to make just 5 portions.
The ingredients for the recipe = Oats, Milk, Sugar
Hence:
For Oats
8 portions of porridge = 400g of oats
5 portions of porridge = x
Cross Multiply
8x = 5 × 400
x = 5 × 400/8
x = 250g of oats
For Milk
8 portions of porridge = 1.2 L of milk
5 portions of porridge = x
Cross Multiply
8x = 5 × 1.2
x = 5 × 1.2/8
x = 0.75 L of milk
For sugar
8 portions of porridge = 40g of sugar
5 portions of porridge = x
Cross Multiply
8x = 5 × 40
x = 5 × 40/8
x = 25g of sugar
Hence:
5 portions of porridge requires
250g of oats, 0.75L of milk and 25g of sugar
