Answer:
Roots = { 2, 5}
Vertex = (3.5, - 2.25)
Step-by-step explanation:
Roots
From the graph
x = {2, 5}
From factoring the equation
(x - 2)(x - 5) = 0
x = {2, 5}
--------------------------
The equation turns at the vertex
From the graph
(3.5, -2.25)
From the equation
X coordinate of vertex
x = -b/2a
x = 7/2 = 3.5
y = (3.5)² - 7(3.5) + 10
y = 12.25 -24.5 + 10
y = -2.25

Profit, P(x), is the difference between revenue, R(x), and cost, C(x), so P(x) = R(x) - CC). Which
expression represents P(x), if R(I) = 224 – 3x3 + 2x – 1 and C(x) = 24 – + 22 + 3?

I NEED HELP ASAP
Answer:
Step-by-step explanation:
Profit, P(x), is the difference between revenue, R(x), and cost, C(x)
R(x) = 2x^4 - 3x^3 + 2x - 1
C(x) = x^4 -x^2 + 2x + 3
Substituting into the equation
P(x) = R(x) - C(x)
= (2x^4 - 3x^3 + 2x - 1) - (x^4 -x^2 + 2x + 3)
= x^4 - 3x^3 + x^2 - 4
The answer is the lower left option.
Answer:
[tex]P(x)=x^4-3x^3+x^2-4[/tex]
(This is the option found in the lower-left corner)
Step-by-step explanation:
When given the following functions,
[tex]R(x)=2x^4-3x^3+2x-1[/tex]
[tex]C(x)=x^4-x^2+2x+3[/tex]
The problem asks one to find ([tex]P(x)[/tex]), moreover, one is given the following information,
[tex](P(x))=(R(x))-(C(x))[/tex]
Substitute,
[tex]P(x)=(2x^4-3x^3+2x-1)-(x^4-x^2+2x+3)[/tex]
Simplify, multiply everything in the second parenthesis by the negative sign outside of it,
[tex]P(x)=2x^4-3x^3+2x-1-x^4+x^2-2x-3[/tex]
Combine like terms, only operations between coefficients of the same variable with the same degree (exponent) can be performed,
[tex]P(x)=x^4-3x^3+x^2-4[/tex]
Helppp I’m on a math test

3√6 + 2√2×2×6+ 7√3×3×6
3√6 +2 ×2√6 + 7 ×3√6
3√6 +4√6 + 21√6
28√6
This question is kinda confusing I need help
Answer:
D) p³ + 2; when p = 3 the number of plants is 29.
Step-by-step explanation:
Illiana cubed (³) the number of original plants, p, in the garden. Then, she added 2 more plants. We will use n for the number of total plants.
So, the equation should be p³ + 2. Substitute our value for p into the equation and solve.
p³ + 2 = n
3³ + 2 = n
27 + 2 = n
29 = n
There are 29 total plants.
The answer, then, is the last option, p³ + 2; when p = 3 the number of plants is 29.
Good luck ^^

trigonometry. please help
Answer:
C) 3/5
Step-by-step explanation:
Have you heard of this way to memorize the trig ratios?
SOH-CAH-TOA (Say it out loud so you remember it.)
It represents these ratios:
Sine = opposite side / hypotenuse
Cosine = adjacent side / hypotenuse
Tangent = opposite side / adjacent side
In this problem, cos C = adj / hyp = BC / AC = 24 / 40.
That simplifies to 3/5

1. A box has square ends. Its length is 13 cm longer than its width and the volume of the box is 60 cubic centimeters. What are the dimensions of the box?
Answer:
2 cm
Step-by-step explanation:
Given that
The length is 13 cm longer than its width
And, the volume of the box is 60cm^3
We need to find out the dimension of the box
Since the box has square ends
So,
the height is equivalent to the width
Let us assume the width be W so the height also be W
Now the length is W + 13
The volume is
W × W × (W + 13) = 60
After solving this W is 2 cm

A translation is a type of transformation that moves each point in a figure the same distance in the same direction.
Find the area of the figure.
4 ft
3 ft
Bft
3 ft
3.ft
2 ft
2 ft
9514 1404 393
Answer:
32 ft^2
Step-by-step explanation:
The area can be figured several ways. Here are two of them.
__
Add components
The figure can be divided into two smaller rectangles, (b) and (d) in the attached drawing. The area of each is the product of its dimensions.
Area b = (4 ft)(3 ft) = 12 ft^2
Area d = (10 ft)(2 ft) = 20 ft^2
Area of the figure is Area b + Area d = 12 ft^2 + 20 ft^2 = 32 ft^2.
__
Subtract white space
The figure is bounded by an overall rectangle that is 10 ft wide and 5 ft high. The area of that rectangle is
Area a+b+c+d = (10 ft)(5 ft) = 50 ft^2
The area of whitespace 'a' is ...
Area a = (3 ft)(3 ft) = 9 ft^2
Area c has the same dimensions, so the same area. The area of the figure is the area of the bounding rectangle less the area of the two corner white spaces (a) and (c).
Area of the figure is ...
Area a+b+c+d -Area a -Area c = 50 ft^2 -9 ft^2 -9 ft^2 = 32 ft^2.

Answer:
11 m= 3 12 slope is 4 and y intercept is 2
Step-by-step explanation:
11 slope = gradient of a line formulae y2-y1 / x2 - x1
12-6 / 4-2 =3
12 slope is the gradient so and is found as m in the equation y=mx + c
so 4 is the slope and the y intercept is where x= 0 so y = 2
