Answer:
[tex]n=0,\\n=6[/tex]
Step-by-step explanation:
Given [tex]n^2-6n=0[/tex], we can factor out an [tex]n[/tex] from each of the terms on the left side of the equation:
[tex]n(n-6)=0[/tex]
Since we have two factors that multiply to zero, we can set each of them to zero and solve for [tex]n[/tex], because zero multiplied by anything is equal to zero. Therefore, as long as either [tex]n[/tex] or [tex]n-6[/tex] is equal to zero, the other factor can be any real number and the equation would still hold true.
Therefore, we have the following cases:
[tex]\begin{cases}n=0,\\n-6=0\end{cases}[/tex]
Solving, we get:
[tex]\begin{cases}n=0, n=\boxed{0}\\n-6=0, n=\boxed{6}\end{cases}[/tex]
[tex]\\ \sf\longmapsto n^2-6n=0[/tex]
Take n common[tex]\\ \sf\longmapsto n(n-6)=0[/tex]
Now
[tex]\\ \sf\longmapsto n=0\:or \:(n-6)=0[/tex]
[tex]\\ \sf\longmapsto n=0\:or \;n=6[/tex]
Hence roots of the equation are 0 and 6 .

NEED THE ANSWER ASAP, PLEASE HELP!! What are the coordinates of the focus of the parabola?
y=−18x2−2x−4
Answer:
Vertex is (-8, 4) not one of the answers offered!
Step-by-step explanation:
Factor -1/8 out of the first two terms. Leave a space inside parentheses in which to add a number.
[tex]y=-\frac{1}{8}(x^2 + 16x + \text{-----})-4[/tex]
Complete the square by squaring half the coefficient of x and adding it in the space.
[tex](\frac{16}{2})^2=64[/tex]
Add 64 in the space you made, then compensate for that at the end of the expression by subtracting [tex]-\frac{1}{8}(64)=-8[/tex]
[tex]y=-\frac{1}{8}(x^2+16x+64)-4+8\\y=-\frac{1}{8}(x+8)^2+4[/tex]
The x-coordinate of the vertex is the opposite of +8, the number inside the parentheses. The y-coordinate of the vertex is the number at the end of the expression.
V(-8, 4)

Answer:32 feet
Step-by-step explanation:
Three numbers are C, BC, and ADC. The digits B and C are multiples of 3. If C×BC=ADC and A+D=B, find the numbers C, BC, and ADC.
Suppose c = 5 and A = 85 degrees.
Answer:
a = 4.98
b = 0.44
B = 5
Concept:
Here, we need to know the idea of the Pythagorean theorem and basic trigonometry ratios.
Pythagorean theorem: a² + b² = c²
a = legb = legc = hypotenuseTrigonometry ratios:
Sine = Opposite / Hypotenuse = O/HCosine = Adjacent / Hypotenuse = A/HTangent = Opposite / Adjacent = O/ASolve:
**Disclaimer** The question did not clarify which place did it required to be rounded to as some of the values are infinite. I rounded to the hundredth place. If it is fine, then you may refer to my answers. If it is not, then you may tell me and I'll redo it.
Given information
c = 5
A = 85°
PART ONE: Find the value of [a]
sin (A) = Opposite / Hypotenuse = a / c
sin (85) = a / 5
a = 5 · sin (85)
a = 4.98
PART TWO: Find the value of [b]
cos (A) = Adjacent / Hypotenuse = b / c
cos (85) = b / 5
b = 5 · cos (85)
b = 0.44
PART THREE: Find the value of [B]
Since the triangle as a right angle sign, meaning it is a right triangle.
Therefore, the corner angle is 90°.
90 - 85 = 5°
Hope this helps!! :)

The double bar graph shows how long, on average, different
animals live both in the wild and in captivity.
Which animal's life span in captivity has the least difference from
its life span in the wild?
ears
Answer: Cheetah
Step-by-step explanation: I got it right on the test :)
The animal with the least difference is cheetah with a value of 5
From the double bar chart attached :
Life span in wild is = blue bar
Life span in wild is = blue bar Life span in captivity = brown bar
Calculating the approximate difference between the two bar values as obtained from the graph :
CHEETAH = 17 - 12 = 5
POLAR = 35 - 20 = 15
TIGER = 26 - 20 = 6
GIANT PANDA = 30 - 20 = 10
LEOPARD = 28 - 20
The animal with the least difference between it's span in the wild and in captivity is CHEETAH with a value of 5.

Answer:
Step-by-step explanation:
The slope or, gradient is the rate of change of a linear function( a function which can be represented by a line). We find a slope between two arbitrary pair of points( arbitrary means what the question given us). One point we are given is (0,4) and an another point we are given is (2,1). Now we use the slope formula,
[tex]\frac{change in y }{change in x}[/tex]
So let plug in the values,
[tex]\frac{4-1}{0-2} =\frac{3}{-2} =-\frac{3}{2}[/tex]
The slope is -3/2

-21 - 8a = -5(a +6)
Step by step if possible
Answer:
Step-by-step explanation:
First multiply the -5 to (a+6)
The equation will look like this
-21 - 8a = -5a -30
then move the numbers around where you have a value times on one side, and a normal value on the other
add -5a to -8a, and add -21 to -30
the equation should look like this:
-13a = -51
then you need to get the a by itself, so divide -13 by -51
a= 13/51 (as a fraction with 13 on top)
in the polynomial below.

Type the correct answer in each box. A circle is centered at the point (-3, 2) and passes through the point (1, 5). The radius of the circle is units. The point (-7, ) lies on this circle.
Answer:
The circle has like an equation: (x+3)²+(y-2)²=r²
If x=1 then y=5 ==>(1+3)²+(5-2)²=r²==>4²+3²=r²==>r=5 (the radius)
if x=-7 then (-7+3)²+(y-2)²=25 ==> (y-2)²=25-16==>y=2+3 or y=2-3
The points (-7,5) and (-7,-1) are on the circle.

Answer:
A) y = 4
B) x = 5
Step-by-step explanation:
for a), the line is horizontal. The y-value doesn't change--it stays at 4.
For b), the line is vertical. So the x-value doesn't change--it stays at 5.
