2. TU, UV and TV are mid-segments
3. Definition of mid-segment
4. Division property of equality
6. SSS similarity theorem
Solution:
Step 1: Given
T is the midpoint of QR.
U is the midpoint of QS.
V is the midpoint of RS.
Step 2: Mid-segments connects midpoints of opposite sides.
TU, UV and TV are mid-segments.
Step 3: By definition of mid-segment
A triangle mid-segment is parallel to the third side of the triangle and is half of the length of the third side.
and
Step 4: By division property of equality
Divide first segment by RS, second segment by QR and third segment by SQ.
Step 5: By transitive property
Step 6: From the above steps, the sides of the triangle are congruent.
By SSS similarity theorem,
Hence proved.
Answer:
The sales tax is 8%
Explanation:
We are given that:
The price of the rocket is $24 and the sales tax is $1.92
To get the percentage of the sales tax, all we have to do is divide the sales tax by the price of the rocket and then multiply the quotient by 100 (to convert the ratio to percentage)
This is done as follows:
% of sales tax =
% of sales tax = %
Hope this helps :)
Answer:
First three terms = 28, 22, and 16
Step-by-step explanation:
The formula for the nth term of an arithmetic sequence is given by:
an = a1 + (n-1)d, where:
Step 1: Find a1:
We can find a1 by substituting 10 for an, 4 for n, and -6 for d in the nth term formula:
10 = a1 + (4 - 1) * -6
10 = a1 + 3 * -6
(10 = a1 - 18) + 18
28 = a1
Thus, the first term is 28.
Step 2: Find a2 (the second term):
Now, we can find the second term by substituting 28 for a1, 2 for n, and -6 for d in the nth term formula:
a2 = 28 + (2 - 1) * -6
a2 = 28 + 1 * -6
a2 = 28 - 6
a2 = 22
Thus, the second term is 22.
Step 3: Find a3 (the third term):
Now, we can find the third term by substituting 28 for a2, 3 for n, and -6 for d in the nth term formula:
a3 = 28 + (3 - 1) * -6
a3 = 28 + 2 * -6
a3 = 28 - 12
a3 = 16
Thus, the third term is 16.
Step 4: Write the first three terms:
Therefore, the first three terms of the arithmetic series are 28, 22, and 16.

Answer:
B. The axis of symmetry is x=1.
F. The vertex is (1, 7).
G. The y-intercept is (0, 10).
Step-by-step explanation:
A graph of the function is helpful sorting this out.
_____
For quadratic ax² +bx +c, the axis of symmetry is x=-b/(2a). Here, that is ...
x = -(-6)/(2·3)
x = 1 . . . . axis of symmetry
This is also the x-coordinate of the vertex. The y-coordinate of the vertex can be found by evaluating the expression for this value of x:
3·1² -6·1 +10 = 7
so the vertex is (1, 7).
__
The y-intercept is the constant, the value of the function when x=0. Here, that is 10, so the coordinates of the y-intercept are (0, 10).
