Answer:
9.6 cm
Step-by-step explanation:
Since the shapes are similar, we can write a proportion. Let x be the length of MN.
9/12 = 7.2/x Write a proportion.
9x = 12(7.2) Use cross products.
9x = 86.4 Multiply.
x = 9.6 Divide both sides by 9.
Side MN is 9.6 cm.

Order these numbers from least to greatest 32/5 6.43 \35 6
Answer:
6.43, 32/5,35/6
Step-by-step explanation:
6 is the least number so its going to go first
next,
32/5 is less than 35/6 so 32/5 will go in the middle and 35/6 will go last
Suppose ΔDEF is the image of a translation of ΔABC. If D is at (−6, −2), what translation rule maps ΔABC to ΔDEF? * Captionless Image T⟨9, 2⟩(ΔABC) = ΔDEF T⟨9, –2⟩(ΔABC) = ΔDEF T⟨–9, –2⟩(ΔABC) = ΔDEF T⟨−9, 2⟩(ΔABC) = ΔDEF
Answer:
T⟨–9, –2⟩(ΔABC) = ΔDEF
Step-by-step explanation:
The question ask what the translation from A is to D(-6,-2). When you solve, you will get (-9,-2) as your answer.

How do i solve this slope of a line from a graph?
Answer:
How you solve it is you pick two points on a line and figure out their coordinates. Determine the difference in the y-coordinates of those two points. Then you also do the same thing with the x-coordinates. Then you divide the difference in the Y and X coordinates .
Step-by-step explanation:
hope this helps 100% sure though that it is right.

Answer:
The graph shows a polynomial.The real zeros are x = -2, 3, 5.The least degree the polynomial can have is 3.Step-by-step explanation:
There is nothing to indicate the graph is not of a polynomial function. Its zeros are the x=intercepts: -2, 3, 5. There are 3 of them, so that is the least degree the polynomial might have.
The graph shows a polynomial.The real zeros are x = -2, 3, 5.The least degree the polynomial can have is 3._____

Answer:
X is 70 degrees
Step-by-step explanation:
Answer:
X is 70 degrees
Step-by-step explanation:
all triangles and straight lines are up to 180 degrees so
180-120=60
we now have 2 angles, so now we need to subtract from 180 to get the missing number
180-60-50=70

Time gained 15 pounds from "Quarantine" snacking
Represent situation below as an integer.
Answer:
15
Step-by-step explanation:
integers are any whole real, whole number, no matter if it's negative or positive. in this case, Time GAINED pounds, so it would make it a positive number.
now, if you were LOSING 15 pounds, it would be -15.
What is the value of the expression below when w = 3. 4w^2 - 7w - 8
Step-by-step explanation: The prime factorization of 4320 is
2•2•2•2•2•3•3•3•5
To be able to remove something from under the radical, there have to be 2 instances of it (because we are taking a square i.e. second root).
√ 4320 = √ 2•2•2•2•2•3•3•3•5 =2•2•3•√ 30 =
± 12 • √ 30
√ 30 , rounded to 4 decimal digits, is 5.4772
So now we are looking at:
w = ( -40 ± 12 • 5.477 ) / -34
Two real solutions:
w =(-40+√4320)/-34=(20-6√ 30 )/17= -0.757
or:
w =(-40-√4320)/-34=(20+6√ 30 )/17= 3.110

find the equation of the linear function represented by the table below in slope-intercept form. picture of table is below
Answer:
[tex] y = 3x + 2 [/tex]
Step-by-step explanation:
The equation of a linear function in slope-intercept form is: y = mx + b, where, m = slope, and b = y-intercept.
Find slope (m) of the linear function by using any two points, say (3, 11) and (7, 23):
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{23 - 11}{7 - 3} = \frac{12}{4} = 3 [/tex]
To find the y-intercept (b), substitute the value of the corrdinate pair of any of the points represented on the table, and the value of the slope (m) into [tex] y = mx + b [/tex].
Substituting, x = -1, y = -1, m = 3.
[tex] y = mx + b [/tex]
[tex] -1 = 3(-1) + b [/tex]
[tex] -1 = -3 + b [/tex]
Add 3 to both sides
[tex] -1 + 3 = b [/tex]
[tex] 2 = b [/tex]
[tex] b = 2 [/tex]
Substitute m = 3, and b = 2 into the equation of the linear function in slope-intercept form:
[tex] y = mx + b [/tex]
[tex] y = 3x + 2 [/tex]
-3=k+3
How do I solve this and can u leave instructions so I can understand what u did
Answer:
k = 6
Step-by-step explanation:
-3=k+3
1) you must isolate the variable (k)
2) subtract each side by 3, to get k=-6
> -3-3=k+3-3
-6=k
now your variable is isolated, so you have your answer.

Answer:
B. 3x^2 +11x -20 = 0
Step-by-step explanation:
For solutions p and q, the quadratic will be
(x -p)(x -q) = 0
We notice that the leading coefficients of the offered answer choices are greater than 1, so it will be convenient to use a value that "clears fractions."
(x -4/3)(x -(-5)) = 0
3(x -4/3)(x +5) = 0 . . . . multiply by 3 to clear the fraction
(3x -4)(x +5) = 0 . . . . . . clear the fraction
3x(x +5) -4(x +5) = 0 . . use the distributive property
3x^2 +15x -4x -20 = 0 . . . . use the distributive property again
3x^2 +11x -20 = 0 . . . . collect terms
_____
The constant in the product of factors is the product of roots:
(x -p)(x -q) = x^2 -(p+q)x +pq
Here, that would mean the constant would be (4/3)(-5) = -20/3.
If we compare the above quadratic to the standard form:
ax^2 +bx +c = 0
we find that we can divide the standard form equation by 'a' to get ...
pq = c/a
That is, c/a = -20/3, so we might start looking for an answer choice that has a leading coefficient of a=3 and a constant of c=-20.

What equation do you get when you solve p = 2l + 2w for w
Answer: When you solve for w the equation is [tex]w= \frac{p-2l}{2}[/tex]
Step-by-step explanation:
p = 2L + 2w subtract 2L from both sides
p -2L = 2L -2L + 2w 2L-2L = 0 om the right; they cancel
p - 2L = 2w now get w alone
(p - 2L)/2 = 2w/2 divide both sides by 2 2w/2 = w 2/2=1 it "cancels"
[tex]\frac{p +2L}{2} = w[/tex] rewrite Reverse sides to put w alone on the left side
[tex]w= \frac{p-2l}{2}[/tex]

If the infinite curve y = e−4x, x ≥ 0, is rotated about the x-axis, find the area of the resulting surface.
Answer: the area of the resulting surface is π/16 [ 4√(17) + In( 4 + √( 17)) ]
Step-by-step explanation:
Given that;
y = e^(-4x), x ≥ 0
then, dy/dx = -4e^(-4x)
now, √( 1 + (dy/dx)² ) = √( 1 + ( -4e^(-4x))²) = √( 1 + 16e^(-8x)
so the surface area of the surface obtaining by rotating the curve y = e^(-4x) on ( 0, ∞ ) about x-axis is,
S = ₀∫^∞ 2πy √( 1 + (dy/dx)² ) dx
S = ₀∫^∞ 2πe^(-4x) . √( 1 + 16e^(-8x) dx
S = 2π. ₀∫^∞ e^(-4x) . √( 1 + 16e^(-8x) dx
so LET 4e^-4x = u ⇒ -16e^(-4x) dx = du
⇒e^-4x dx = du/ -16
so whenx = 0, then u =4 and when x → ∞ then e^(-4x) → 0 so u →0
therefore
S = 2π ₄∫⁰ √(1 + u²) . du/-16
= π/8 ₀∫⁴ √(1 + u²) . du
= π/8 [ u/2√(1 + u²) + 1/2 In ( u + √( 1 + u²) ]₀⁴
WE MAKE USE OF
∫√( a² + u²) du = u/2√(a² + u²) + a²/2 In ( u + √( a² + u²)) + C
so
= π/8 [ 4/2√(1 + 16) + 1/2 In ( 4 + √( 1 + u16 ]
= π/8 [ 2√(17) + 1/2 In ( 4 + √( 17)) ]
= π/16 [ 4√(17) + In( 4 + √( 17)) ]
therefore the area of the resulting surface is π/16 [ 4√(17) + In( 4 + √( 17)) ]
