Answer:
A is the answer
Answer:
the first one is the answer y = (x-2)^2 + 1
Step-by-step explanation:
The vertex form of a quadratic function is y = a(x – h)^2 + k, where a, h, and k are constants. h and k are vertex.
vertex is (2,1) which is (h,k)
passes through (0,5)
Equation is y = a( x - 2)^2 + 1 . now substituting (0,5) in for x and f(x),
5 = a ( 0 - 2) ^2 + 1 and solve for a.....
5 = 4a + 1
5-1 = 4a
4a = 4.......... a = 1
equation becomes y = 1(x-2)^2 + 1 or y= (x-2)^2 + 1

Answer:
UW = 67
Step-by-step explanation:
In order to find UW, we need to add UV and VW because them together makes the entire line, also known in this problem as UW. This is our equation:
UV + UV = UW
This is the equation if you plug the numbers:
19 + 4x - 20 = 6x - 35
Combine like terms to make it easier to do the math:
4x - 1 = 6x - 35
Then do the math:
(4x - 4x) -1 = (6x - 4x) - 35
-1 = 2x - 35
(-1 + 35) = 2x (- 35 + 35)
34 = 2x
34/2 = 2x/2
x = 17
Then you plug in x for the UW expression:
6x - 35
6(17) - 35
102 - 35
67
UW = 67

Answer:

Step-by-step explanation:
The length of AB is found using the distance formula
We need to know the coordinates of A and B
A = (-5,-4) and B = (-3,3)
The distance is
d = sqrt ( (y2-y1)^2 + (x2-x1)^2)
= sqrt( (3 - -4)^2 +(-3 - -5)^2)
= sqrt( (3+4)^2 +(-3+5)^2)
= sqrt(7^2+2^2)
= sqrt(49+4)
= sqrt(53)
=7.280109889

Step-by-step explanation:
Xs = 5 -(0-5) = 5+5 = 10
Ys = -2 -(5-(-2)) = -2 - 7 = -9

Use midpoint formula and assume S(x, y):
(0 + x)/2 = 5 ⇒ x / 2 = 5 ⇒ x = 10(5 + y)/2 = -2 ⇒ 5 + y = -4 ⇒ y = -4 - 5 ⇒ y = -9INSTRUCTIONS: This is a numerical series. Find the missing item

In a GP the second and fourth terms are 0.04 and I respectively find the common ratio and the first term
Answers
Answer:
common ratio=0.5, a1= 0.08
Step-by-step explanation:
r=a3/a2
r=a4/a3
compare both we get:
a3/a2=a4/a3
subtitute a2=0.04 and a4=1
a3/0.04=1/a3
(a3)^2=0.04*1
(a3)^2=0.04
taking square root in both sides
a3=0.02
For r, r=a3/a2
subtitute a3 and a2 above
r=0.02/0.04
r=0.5 common ratio
For a1
r=a2/a1
0.5=0.04/a1
a1=0.04/0.5
a1=0.08
A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.

The common ratio of the geometric sequence is 1/0.02.
What is a geometric sequence?A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.
We have,
Geometric sequence:
The second term = 0.04
The fourth term = 1
In a geometric sequence the nth term is given as:
[tex]a_{n}[/tex] = [tex]a_1 r^{n-1}[/tex]
Second term = 0.04
[tex]a_2[/tex] = 0.04
[tex]a_1 r^1 = 0.04[/tex]
[tex]a_1r[/tex] = 0.04 _____(1)
Fourth term = 1
[tex]a_4 = 1[/tex]
[tex]a_1 r^3[/tex] = 1 _____(2)
From (1) and (2) we get,
0.04/r = 1/r³
r³ = r / 0.04
r² = 1/0.04
r = 1/0.02 ____(3)
Putting (3) in (1) we get
[tex]a_1[/tex] = 0.04 x 0.02 = 0.08
Thus,
The first term of the geometric sequence is 0.08.
The common ratio of the geometric sequence is 1/0.02.
