What is the missing information?The missing information are the vertices of the triangle, given as follows:
X(-3,2).Z(1,-1).Y(3,4).What is the area of a triangle?The area of a triangle is given by half the base multiplied by the height, that is:
A = 0.5bh
For this problem, the have that the base is the length of segment XZ, which is found applying the distance between two points as follows:
[tex]b = \sqrt{(1 + 3)^2+(-1 - 2)^2}[/tex]
b = sqrt(25)
b = 5.
The height is the distance between the midpoint of XZ and Y. The midpoint of XZ(mean of the coordinates) is (-1, 0.5), hence the height is:
[tex]h = \sqrt{(-1 - 3)^2+(4 - 0.5)^2}[/tex]
h = sqrt(4² + 3.5²)
h = 5.32.
Thus the area of the triangle is given by:
A = 0.5 x 5 x 5.32 = 13.3 units².

What is a quadratic equation?
In algebra, a quadratic equation( from Latin quadratus' forecourt') is any equation that can be rearranged in standard form asax^2 + bx + c = 0
where x represents an unknown, and a, b, and c represent known figures, where a ≠ 0. is still, not quadratic, as there's no ax^2 term,( If a = 0( and b ≠ 0) also the equation is direct.)
The figures a, b, and c are the portions of the equation and may be distinguished by calling them, independently, the quadratic measure, the direct measure, and the constant or free term.The values of x that satisfy the equation are called results of the equation, and the roots or bottoms of the expression on its left-hand side. A quadratic equation has at most two solutions.Given,
h(0)=6 ft (six)
v(0)=40 ft/sec (fourty)
h(t)=6+40t-16t2 (equation)
for h=28 ft(twenty eight)
28=6+40t-16t2 (equation)
or 16t2 - 40t + 22 = 0 (equation)

Step-by-step explanation:
The length of a rectangle is 5 in longer than its width.
If the perimeter of the rectangle is 58 in, find its length and width.
Answer:
Length = 17 in
Width = 12 in
Step-by-step explanation:
Formula we use,
→ P = 2(L + W)
Then the value of L and W is,
→ P = 2(L + W)
→ 58 = 2(x + 5 + x)
→ 2(2x + 5) = 58
→ 4x = 58 - 10
→ x = 48/4
→ [ x = 12 ]
Then the width will be,
→ W = x = 12 in
Hence, the width is 12 in.
Now the length will be,
→ L = x + 5 = 12 + 5 = 17 in
Therefore, the length is 17 in.

Answer:so dividing you add a extra zero behind the dot or point while multiplying you decrease the decimal to a whole number
if it is right pls give me brainliest
Step-by-step explanation:The relationship between 0.8 divided by 10^2 and 0.8x10^2 is that 0.8 divided by 10^2 means you add extra zero to the dot like this 0.008 so what it mean is that 10^2 is to add extra zeros in front of the point or dot in 0.8 while 0.8x10^2 decreases the zero like this 80 so we remove the 0 in 0.8 which mean 0.8 is no longer a decimal but a whole number now and then add a extra zero because 10^2 mean add two zeros so if you see a number infornt of 10^ like 2 is how many zeros you add. so you add to extra zeros to 0.8 which decreases
Do children weigh 160 pounds together the oldest weighs 120lbs more how much do they each weigh
Answer:
One child weighs 120lbs, and the other weighs 40lbs.
Step-by-step explanation:
Assuming that you meant "Two" instead of "Do", there are two children that weigh 160 pounds together. If we know that one child weighs 120lbs more, we know that the other child has to weigh 40lbs using the equation below where x represents the weight of the second child:
120 + x = 160
Subtract 120 from both sides
x = 40
FINAL ANSWER: One child weighs 120lbs, and the other weighs 40lbs.

A shirt and a tie are 57 together if the shirt is $29 more than the tie how much money is the Tie worth
Answer:
$14
Step-by-step explanation:
The tie costs x.
The shirt costs x + 29
Together they cost $57.
x + x + 29 = 57
2x + 29 = 57
2x = 28
x = 14
Answer: $14
Answer:
14
Step-by-step explanation:
Tie is X
Shirt is x + 29
So,
X+X+29= 57
2x+29= 57
57-29= 2x
28=2x
X= 14
So tie is 14 bucks

What is Mid-point of a Line segment?
The mid-point of a line segment is a point on the line segment which divides it into two equal parts.
Given is a line segment AB whose mid-point is M with a and b being the coordinates of A and B respectively. Further, Q is the midpoint of AM and T is the midpoint of QM.
[Refer to the image attached for clear explanation]
Since M is the mid-point of AB, therefore the coordinates of point M will be = M [(a + b)/2]
Now, Q is the mid-point of AM. Therefore, the coordinates of Q will be =
[(a + b)/2 + a]/2 = Q [(3a + b)/4]
and
T is the mid-point of QM. Therefore, its coordinates will be =
(a + b)/2 + (3a + b)/4 = T [(5a + 3b)/4]
Hence, the the coordinates of Q and T in terms of a and b is -
Q [(3a + b)/4] and T [(5a + 3b)/4]
