Answer:
Spacing between the posters will be 1.75 each
Step-by-step explanation:
We are given
The length of the wall = 13ft
width of the poster = 2ft ⇒2*3=6ft for three posters
Poster's from end of the wall = 1.75*2 = 3.50ft
let the spacing be = x ⇒ 2x for two spacing between three posters
Total length of the wall = 6 + 3.50 + 2x = 13
2x + 9.50 = 13
2x = 3.50
x = 1.75ft
So the spacing between the posters will be 1.75 each
An 18-pound bag of dog food is $27. What is the constant of proportionality that relates cost in dollars, y, to the number of pounds of dog food, x ?
help please True or false 15=11m.
if m=4?
Answer:
False
Step-by-step explanation:
If F=4 that means 11 x 4 = 44 and 15 does not equal 44.
find the value of c that completes the square
x^2-6x+c
please help me with the math problem and show me how to do these kinds.
Thank you.
Answer:
The answer is 9
Step-by-step explanation:
for the equation:
move the -6x
x^2 + c - 6x
To find c :
c = (b/2)^2
this means you have to divide the coefficient of x by 2 then square the result

The equation that represents the canned goods order is
24x + 64y = 384, where x = number of minutes for
producing fruit cans and y = number of minutes for
producing vegetable cans.
What is the meaning of the y-intercept?
If you can give sample response from edge I will give brainliest!
Answer:
The y intercept is where the number of minutes producing fruit cans is 0 and the value of the number of minutes for producing vegetable cans is on the y-axis.
Step-by-step explanation:
A y-intercept is where the x value is 0 and the y-value is on the y-axis. So, the answer consists of making the x value 0.
Answer:
Sample Answer: The x-intercept, at the point (16, 0) indicates the choice to produce fruit for 16 minutes. In 16 minutes, producing 24 cans of fruit a minute, all 384 cans for the order will be completed. The zero for the y-value represents that no time is spent producing cans of vegetables.
Step-by-step explanation:
Write \sqrt{-40}
−40
in simplest radical form.
Answer:
2*{2*i*√(10) - 20}
Step-by-step explanation:
i will interpret your expression as being
sqrt{-40} − 40. The first term factors to
sqrt{-4*10)
and the second stays as is.
Then we have
sqrt(-4*10) - 40, or
i*2*sqrt(10) - 40, or
2*{2*i*sqrt(10) - 20}, or
2*{2*i*√(10) - 20}
Which polynomial function has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1? f(x) = (x – 2i)(x – 3i) f(x) = (x + 2i)(x + 3i) f(x) = (x – 2)(x – 3)(x – 2i)(x – 3i) f(x) = (x + 2i)(x + 3i)(x – 2i)(x – 3i)
Answer:
[tex]P(x)=(x-2i)(x-3i)[/tex]
Step-by-step explanation:
Build a Polynomial Knowing its Roots
If we know a polynomial has roots x1, x2, ..., xn, then it can be expressed as:
[tex]P(x)=a(x-x1)(x-x2)...(x-xn)[/tex]
Where a is the leading coefficient.
Note the roots appear with their signs changed in the polynomial.
If the polynomial has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1, then:
[tex]P(x)=1(x-2i)(x-3i)[/tex]
[tex]\mathbf{P(x)=(x-2i)(x-3i)}[/tex]

A piece of cardboard has the dimensions (x + 15) inches by (x) inches with the area of 60 in 2 . Write the quadratic equation that represents this and show your work. Then find the possible value(s) for x, and find the actual dimensions of the postcard.
Answer:
[tex]x^2 + 15x - 60 = 0[/tex]
The actual dimension is 18.28 by 3.28
Step-by-step explanation:
Given
Dimension:
[tex](x + 15)\ by\ x[/tex]
[tex]Area = 60in^2[/tex]
Required
Determine the quadratic equation and get the possible values of x
Solving (a): Quadratic Equation.
The cardboard is rectangular in shape.
Hence, Area is calculated as thus:
[tex]Area = Length * Width[/tex]
[tex]60= (x + 15) * x[/tex]
Open Bracket
[tex]60= x^2 + 15x[/tex]
Subtract 60 from both sides
[tex]x^2 + 15x - 60 = 0[/tex]
Hence, the above represents the quadratic equation
Solving (b): The actual dimension
First, we need to solve for x
This can be solved using quadratic formula:
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = 1[/tex]
[tex]b = 15[/tex]
[tex]c = -60[/tex]
So:
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]x = \frac{-15 \± \sqrt{15^2 - 4*1*-60}}{2*1}[/tex]
[tex]x = \frac{-15 \± \sqrt{225 + 240}}{2}[/tex]
[tex]x = \frac{-15 \± \sqrt{465}}{2}[/tex]
[tex]x = \frac{-15 \± \21.56}{2}[/tex]
Split:
[tex]x = \frac{-15 + 21.56}{2}[/tex] or [tex]x = \frac{-15 - 21.56}{2}[/tex]
[tex]x = \frac{6.56}{2}[/tex] or [tex]x = \frac{-36.36}{2}[/tex]
[tex]x = 3.28[/tex] or [tex]x = -18.18[/tex]
But length can't be negative;
So:
[tex]x = 3.28[/tex]
The actual dimensions: [tex](x + 15)\ by\ x[/tex] is
[tex]Length =3.28 +15[/tex]
[tex]Length =18.28[/tex]
[tex]Width = x[/tex]
[tex]Width =3.28[/tex]
The actual dimension is 18.28 by 3.28

Explain, step by step, how to arrive at a single rational number to represent the following expression. Show both a written explanation and the related math work for each step. 1 - 3/4 + (-12 1/4)
Answer:
-30
Step-by-step explanation:
first you should complete the equition of bracket
1-3/4+(-121/4)
= 1-3/4+(-30.25)
= 1-0.75+(-30.25)
=0.25+(-30.25)
=-30
hence the right answer is -30 :)

WHAT'S THE RANGEE??
Answer:
-2 < y ≤ 10
Step-by-step explanation:
The graph's lowest point is at y = -2, and the graph's highest point is at y = 10, so we know it would start off with -2 and end with 10. The dot at the lowest point is not shaded in, indicating that the graph does not include -2. So, we would represent this exclusion in our inequality with a less than (<) sign. As for the highest point at y = 10, it is shaded in, indicating that the graph does include 10. We would show this in our inequality with a less than or equal to sign (≤)

The graph shows the amount of money paid when purchasing bags of caramel corn at the zoo:
A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 10. Four points are shown on the graph on ordered pairs 0, 0 and 1, 3 and 2, 6 and 3, 9. These points are joined by a line. The label on the x-axis is Bags of caramel corn. The title on the y-axis is Total cost in dollars.
What does the point (0, 0) on the graph represent?
Answer:
Step-by-step explanation:
propportinal
means that the points are inproportion
ratios
1:3=2:6=3:7
1/3=2/6=3/7
1/3=1/3=3/7
false
therefor it is not poropoortional
another way is to graph the points and see if a straight line can go though all of them
it can go thoruhg the first 3 but not eh 4th pont (3,7)
not proportional
