Answer:
I think it C
Step-by-step explanation:
Let's solve your equation step-by-step.
(k−4)2=9
Step 1: Simplify both sides of the equation.
k2−8k+16=9
Step 2: Subtract 9 from both sides.
k2−8k+16−9=9−9
k2−8k+7=0
Step 3: Factor left side of equation.
(k−1)(k−7)=0
Step 4: Set factors equal to 0.
k−1=0 or k−7=0
k=1 or k=7
Answer:
k=1 or k=7
Hope this helps! :)
Square both sides:
K -4 = sqrt(9)
With the answer being a square root rewrite with a postive and negative value:
K-4 = sqrt(9)
And
K-4 = -sqrt(9)
Simplify each:
K-4 = 3
And
K-4 = -3
Solving for k in each one you get answer
C. {1,7}

Q4) Identify which of the following are geometric sequences and which are
not
(i) 2, 6, 18, 54.....
(ii) 25,5, 1,
(iii) 1, 4, 9, 16
Answers
Answer:
(i) and (ii)
Step-by-step explanation:
For a sequence to be geometric then the ratio r between consecutive terms must be common.
(1)
2, 6, 18, 54
6 ÷ 2 = 3
18 ÷ 6 = 3
54 ÷ 18 = 3
Here there is a common ratio r = 3 , then sequence is geometric
(ii)
25, 5, 1
[tex]\frac{5}{25}[/tex] = [tex]\frac{1}{5}[/tex] and [tex]\frac{a_{3} }{a_{2} }[/tex] = [tex]\frac{1}{5}[/tex]
There is a common ratio r = [tex]\frac{1}{5}[/tex] , then sequence is geometric
(iii)
1, 4, 9, 16
4 ÷ 1 = 4
9 ÷ 4 = 2.25
16 ÷ 9 = 1.777..
There is no common ratio, then sequence is not geometric

Answer:
x = 23
Step-by-step explanation:
These are supplementary angles so the sum of those angles add up to 180:
3x + 16 + 5x - 20 = 180
8x - 4 = 180
8x = 180 + 4
8x = 184
x = 184/8
x = 23

If a rectangular cross-section with coordinates at (1, 1), (1, 4), (3, 4) and (3, 1) is rotated about the line y = 1, what will be the resulting three-dimensional object?
Answers
Answer:
cylinder
Step-by-step explanation:
Answer
cylinder!!
Step-by-step explanation:
so the points "(1, 1), (1, 4), (3, 4) and (3, 1)" they are all positive so this makes this easier tbh so it looks like this once u put them on a grah
. .
. .
its a rectangle then it says to rotate on y = 1 which u look at the graph u just put this rectangle on its side like this
. .
. .
so then look at the answer options
A.) Cone
B.)Cylinder
C.)Sphere
D.)Pyramid
so it CANT be A bc 1 its a rectangle and if it was a cone it would have 3 points, not 4, bc it would be a triangle
It can be B bc on a graph it will be 2D and a Cylinder has 4 points on a graph(in 2D) which the problem is telling you to make something 2D into something 3D...and is a rectangle in 2D
It CANT be a C bc in 2D it would be a circle and straight up, a square isnt a circle, and the points on the problem is a square ant there would be so many points to put down if it was a circle
It CANT be a D bc once again this would be a triangle and that would have 3 points, or maybe 5(if your looking overhead of the Pyramid where u can see all 4 corners, like a square then the middle point) so a square has all equal sides, rectagle does not, it has 2 and 2 equal sides. 2 sides being small and paralell, and 2 long sides being parallel.

3/4 x 6=18/4
Step-by-step explanation:
Reduce fraction to lowest terms
18 over 4

18 ÷ 2
4 ÷ 2

9 /2
2 is the greatest common divisor of 18 and 4. Reduce by dividing both numerator and denominator by 2.
Step 2 of 2: Simplify, sub-step b: Convert improper fraction to mixed number.
Convert improper fraction to mixed number

The current population of Rochester is 211,000 and is decreasing at a rate of 4.1% every ten years. Which function can be used to find the population 30 years from now?
Answers
Answer:
211,000(0.97)t
Step-by-step explanation:
Firstly; Write the exponential decay function for this situation.
y = a(1 – r)t Write the formula.
= 211,000(1 – 0.041)t Substitute 1700 for a and 0.03 for r.
= 211,000(0.97)t Simplify.
Next; Find the population in function.
y = 1700 Substitute 12 for t.
≈ 1180 Use a calculator and round to the nearest whole number.
The population in 30 years function will be approximately 211,000(0.97)t.

Answers
Answer:
y=x/3 - 4
Step-by-step explanation:
add x to get x to the other side
3y= x-12
divide by 3 on both sides to get y by itself y= x/3 - 4 is simplest form
Answer:
slope intercept form is y=mx+b
add x to both sides : 3y=x-12
