Answer:
y=x^2 -5x+4
Step-by-step explanation:
F(x)= -x+1
G(x)-x+4
(-x+1)(-x+4) = x^2 -4x-1x+4 = x^2-5x+4
=======================================================
Explanation:
The f(x) function goes through (0,1) and (1,0). It's slope is
m = (y2-y1)/(x2-x1)
m = (0-1)/(1-0)
m = -1
The y intercept is b = 1 because this is where the blue line crosses the y axis.
We go from y = mx+b to y = -1x+1, or simply y = -x+1.
So f(x) = -x+1
Through similar steps, you should find that g(x) = -x+4
Both f(x) and g(x) have the same slope, which makes them parallel lines.
-----------------------------------
Once we know what f(x) and g(x) are, we multiply them out like so:
f(x) * g(x) = ( f(x) ) * ( g(x) )
f(x) * g(x) = ( -x+1 ) * ( -x+4 )
f(x) * g(x) = w(-x+4) ..... let w = -x+1
f(x) * g(x) = -xw + 4w ... distribute
f(x) * g(x) = -x( w ) + 4( w )
f(x) * g(x) = -x( -x+1 ) + 4( -x+1 ) ... plug in w = -x+1
f(x) * g(x) = x^2 - x - 4x + 4 ... distribute twice more
f(x) * g(x) = x^2 - 5x + 4
You could use the FOIL rule or box method as alternative routes to get this answer. I prefer the box method because the FOIL rule is only limited to multiplying binomials, while the box method allows you to multiply two polynomials of any length.

The boys kept adding sand, and ten minutes later the volume of the sand cone had increased by 30%. What is the exact volume of the sand cone now? (Show your work. Remember you can draw a picture to help you solve the problem.)
Answer:
a) 84π b) 109.2π
Step-by-step explanation:
The formula to find this is v=πr^2h/3
r=d/2. so the radius (r) is 6 because you have to divide the diameter (12) by 2. and the height is 7. so, 6^2=36 and 36x7=252.
252/3=84
and because the question is asking for the EXACT value, you need to just put the pi symbol next to it. Final answer for a is 84π
B) you need to find 30% of 84, which is 25.2 and add it to 84, and you will get 109.2! Final answer is 109.2π.

Which angle is coterminal with a 110° angle?
O A. An angle measuring 460°
O B. An angle measuring -110°
C. An angle measuring 290°
O D. An angle measuring 470°
Answer:
D. An angle measuring 470*
Step-by-step explanation:In this question
The coterminal angle for 110° is 470°.
What are coterminal angles?"Coterminal angles are two (or more) angles that have their initial and terminal sides in the same positions. However, the angle measures differ either because one angle is measured clockwise and the other is measured counterclockwise".
For the given situation,
The angle is 110°.
The coterminal angles can be determined by adding or subtracting 360° to the given angle.
For 110° = [tex]360+110[/tex]
⇒ [tex]470[/tex]°
Hence we can conclude that the coterminal angle for 110° is 470°.

c = 22.3 km
Step-by-step explanation:
You can solve this problem using cosine law:
[tex] {c}^{2} = {a}^{2} + {b}^{2} - 2ab \cos( \gamma ) [/tex]
where a and b are the legs of the triangle, c is the unknown length and the angle gamma is the angle opposite length c. We know that
a = 50 km
b= 52.4 km
gamma = 25°
c^2 = (50 km)^2 + (52.4 km)^2 -2(50)(52.4)cos25°
= 496.707 km^2
or
c = 22.3 km
Ms. Edwards can spend, at most, $250 on new books for the school library. She will buy a reference book on birds for $30 and a reference book on the planets for $14.95. Let x represent the amount of money Ms. Edwards can spend on other books. Write an inequality that correctly describes this situation.
Answer:
x ≤ 205.05
Step-by-step explanation:
x = dollar amt remaining for other books
30 + 14.95 + x ≤ 250
44.95 + x ≤ 250
x ≤ 205.05
x ≤ $205.05 is an inequality that correctly describes this situation.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
Let's use x to represent the amount of money Ms. Edwards can spend on other books.
We know that Ms. Edwards can spend at most $250 in total and that she will already spend $30 + $14.95 = $44.95 on the reference books on birds and planets.
Therefore, the amount she has left to spend on other books is:
x = $250 - $44.95
x = $205.05
Ms. Edwards can spend up to $205.05 on other books.
To write this as an inequality, we can use the less than or equal symbol since Ms. Edwards cannot spend more than $205.05:
x ≤ $205.05
Therefore, the inequality that correctly describes this situation is:
x ≤ $205.05

Answer:
A: 46 meters at 3 seconds
B: 0 meters at 6.033 seconds
C. It depends where the tree is
D. 6.033 seconds
Step-by-step explanation:
A. To find max height, we need to find the vertex.
We can do this by using vertex from y=a(x-h)+k for y=a^2+b^2+c^2
h(t) = -5t^2+30t+1
h(t)+45 = - 5x^2+30x+45+1
h(t)+45= -5(x^2-6x-9)+1
h(t)+45 = -5(x-3)^2+1
h(t) = -5(x-3)^2+46
Hence, the max height is 46 at 3 seconds
B. The minimum height is 0 meters because of the problem
C. It depends because the parabola intersects x=10 in 2 places meaning that you need the tree to be in either of these two places to intercept the horseshoe

Step-by-step explanation:
Mateyo is building a rectangular prism with a volume of 1000 cubic units. The height of the prism is 10 units. Mateyo claims that the base of the prism must be a square. Draw a base for th rectangular prism that shows that Mateyo is not correct. Remember to label the units.
Answer:
See attachment for drawing
Step-by-step explanation:
Given
[tex]Volume = 1000[/tex]
[tex]Height = 10[/tex]
Required
Drawing that proves Mateyo wrong
First, calculate the base area
[tex]Volume = Base\ Area * Height[/tex]
This gives:
[tex]1000= Base\ Area * 10[/tex]
Divide both sides by 10
[tex]100= Base\ Area[/tex]
Rewrite as:
[tex]Base\ Area = 100[/tex]
The base area is calculated as:
[tex]Base\ Area = Length * Width[/tex]
So, we have:
[tex]Length * Width = 100[/tex]
Mateyo's claim can be interpreted as:
[tex]Length = Width = 10[/tex]
However, there are other possible cases such that:
[tex]Length \ne Width[/tex]
For instance:
[tex]Length = 20[/tex]
[tex]Width = 5[/tex]

Answer:
The surface area of the cuboid is 648 m^2
Step-by-step explanation:
What we have here is cuboidal in outlook
By using the formula for the surface area of a cuboid, we can get the surface area of the shape
mathematically, we have the surface area of a cuboid as follows;
2(lb + lh + bh)
where l is the length, b is the breadth (width) and h is the height
We can have the length as 9 m, the width as 9 m and the height as 13.5 m
Substituting these values, we have the surface area of the cuboid as;
A = 2(9(9) + 9(13.5) + 9(13.5))
A = 2(81 + 243)
A= 2(324)
A = 648 m^2

Answer:
x = 16, x = 17
Step-by-step explanation:
Given a line parallel to a side of a triangle and it intersects the other 2 sides, then it divides those sides proportionally, that is
[tex]\frac{x+8}{20}[/tex] = [tex]\frac{2x-5}{22.5}[/tex] ( cross- multiply )
20(2x - 5) = 22.5(x + 8)
40x - 100 = 22.5x + 180 ( subtract 22.5x from both sides )
17.5x - 100 = 180 ( add 100 to both sides )
17.5x = 280 ( divide both sides by 17.5 )
x = 16
----------------------------------------------------------------
[tex]\frac{2x+8}{28}[/tex] = [tex]\frac{5x-4}{82-28}[/tex] = [tex]\frac{5x-4}{54}[/tex] ( cross- multiply )
28(5x - 4) = 54(2x + 8)
140x - 112 = 108x + 432 ( subtract 108x from both sides )
32x - 112 = 432 ( add 112 to both sides )
32x = 544 ( divide both sides by 32 )
x = 17

Answer:
The answer should be 10c - 4d
Step-by-step explanation:
3c + 7c - 9d + 5d = 10c - 4d
Step-by-step explanation:
First you add up 3c and 7c as they have the same parameter. That makes 10c. Then calculate 5d-9d which equals -4d. You can change the order of 5d-9d in a way that you would reduce the larger number from the smaller number so that you could calculate it easily like that. The final Ander 2ould be 10c-4d
