Find AB
I need help !
9514 1404 393
Answer:
d. AB = 54
Step-by-step explanation:
The triangle is isosceles, so AB = AC.
(4x +6) = (5x -6)
12 = x . . . . . . . . . . . . add 6-4x to both sides
Then the length of AB is ...
AB = 4x +6 = 4(12) +6 = 48 +6
AB = 54

In parallelogram ROCK shown below, m angle ROS=65^ and m angle OCK=70^ . What is the measure of angle R ? Explain why
Answer:
angke R is 70
Step-by-step explanation:
opposite angle of a parallelogram are equal.
I.e. angle C = angle R = 70
Answer:
70
Step-by-step explanation:
In a parallelogram, (I) opposite angles are congruent.
(II) Adjacent angles are supplementary.
(III) Opposite sides are equal and parallel.
(Iv) Diagonals bisect each other
Angle R and angle C are opposite angles as they don't share any arm's(sides).
∠R = ∠C = 70

Answer:
9 pi
Step-by-step explanation:
First find the circumference of the circle
C =2 * pi *r
C = 2 * pi *9
C = 18 pi
This is a semicircle which is 1/2 of a circle
Take 1/2 of the circumference
1/2 C = 1/2 ( 18 pi)
1/2 C = 9 pi
Two numbers multiply to be 4 and add to be -5
Answer:
-1, -4
Step-by-step explanation:
x + y = -5
x×y = 4
=>
x = -5 - y
=> (-5 - y) × y = 4
-5y - y² = 4
y² + 5y + 4 = 0
the solution for a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
a = 1
b = 5
c = 4
x = (-5 ± sqrt(25 - 16))/2 = (-5 ± 3)/2
=> x = -2/2 = -1 or x = -8/2 = -4
=> y = 4/-1 = -4 or y = 4/-4 = -1
since the sequence in an addition and multiplication does not make any difference, the two numbers are simply -1 and -4

How many solutions does this equation have one, none, or infinite 12+2i-i=9i+6
Answer:
i=3/4
Step-by-step explanation:
Assuming that we are treating "i" as a variable and not the constant "i":
12+2i-i=9i+6
12+i=9i+6
12=8i+6
6=8i
8i=6
i=6/8
i=3/4
Therefore, the equation has only one real solution which is i=3/4

Suppose that many large samples were taken from a population and the sample proportion centered around 0.25 which of the following is most likely the population parameter
0.25
0.45
0.35
0.15
Answer:
0.25
Step-by-step explanation:
Hope it helps, sense it’s centered around 0.25 then the parameter would be 0.25
To It’s centered around 0.25 then the parameter would be 0.25.
We have given,
Suppose that many large samples were taken from a population and the sample proportion centered around 0.25
We have to determine which of the given is most likely the population parameter.
What is the center parameter in the large sample?
A sample means from any distribution. We could have a left-skewed or a right-skewed distribution.
To It’s centered around 0.25 then the parameter would be 0.25
Therefore option A(0.25) is correct
To It’s centered around 0.25 then the parameter would be 0.25.

Point k is on line segment JL. Given JL = 4x+2, KL = 5x-6, and JK = 3x, determine the numerical length of JK.
Answer:
6 units
Step-by-step explanation:
JK + KL = JL
3x + 5x-6 = 4x+2
8x-6 = 4x+2
subtract 4x from each side to get:
4x - 6 = 2
add 6 to each side to get:
4x = 8
x = 2
JK = 3x and x=2 so JK = (3)(2) or 6
The numerical length of JK = 6
What is Line Segment?
" A line segment is a line section that can link two points. "
We know that point K is divide line JL
Given that JL = 4x+2
KL = 5x-6
JK = 3x
So, Equation is JK+KL = JL
3x+5x-6 = 4x+2
8x-6 = 4x+2
8x-4x = 2+6
4x = 8
x = 8/4
x = 2
So , numerical length of JK = 3x
JK = 3×2
JK = 6
Hence , length of JK is 6

A painting without its frame has a width 2.5 times its height, h, in inches. Its frame is 3 in. wide all along its perimeter. What is an expression for the area of the framed painting in terms of h? A. 2.5h2 B. 2.5h2 + 6 C. 2.5h2 + 36 D. 2.5h2 + 21h + 36
Answer:
2.5h^2 + 21h + 36
Step-by-step explanation:
Height = h
width = 2.5h
border = 3 in.
Overall height = h+6
Overall width = 2.5h+6
Overall area
= (h+6)(2.5h+6)
= 2.5h^2 + 15h + 6h +36
= 2.5h^2 + 21h + 36
