a) x^2 - 10x + 25 = 0
b) x^2 - 4x - 5 = 0
(preciso da montagem da conta, junto com o resultado)
Answer:
Step-by-step explanation:
a) x² - 10x + 25 = 0
(x-5)²=0
x-5=0
x=5
b) x² - 4x - 5 = 0
⇒ ( x 2 − 4 x + 4 ) − 5 − 4 = 0
⇒ ( x 2 − 4 x + 4 ) − 9 = 0
( x − 2 ) 2 − 9 = 0 ⇒
( x − 2 ) 2 = 9 ⇒
( x − 2 ) = ± √ 9 (don't forget the ± !) ⇒
x= − 1 x = 5

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
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

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?
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.
:) have a good day
btw answer is
cylinder!!Find the surface area of each prism or pyramid. Round to the nearest tenth if necessary. Can someone help me with 17-19 for 30 points

Tell if the Ratio is Part-to-part or part-to-whole
4 apples to 3 oranges
Answer: Part-to-part
Step-by-step explanation:
This is a part-to-part, because they show part of apples, and part of oranges. This ratio when set up is 4:3. If the ratio was part-to-whole, then the apples would be compared to the total amount of oranges and apples. The ratio for part-to-whole would be 4:7.
Hope this helps!
