since U is the midpoint of QT, QT = 2(QU)
similarly, QS = 2 (QR)
because QR is parallel to QS and QU is parallel to QT, triangle QUR is similar to triangle QTS. therefore, the scaling factor between QT/QU and QS/QR is equal to the scaling factor between RU and ST.
therefore,
ST = 2(RU)

What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.
Given is a graph of the amount of water in a bathtub with respect to time.
A) This statement means that the slope of the line at 10 : 01 pm is smaller than that of at 10 : 14 pm.
The line is steeper at 10:01 pm than that at 10:14 pm. That is the tangent of the angle making with the x axis at 10:01 pm is higher than that at 10:14 pm.
So the tub is filling at a faster rate at 10:01 pm than at 10:14 pm.
B) At 10:06 pm, the amount of water is constant at 30 gallons. So this statement is correct.
C) The maximum amount of water in the tub was about 35 gallons is a correct statement since after that the tub was draining.
D) The amount of water in the tub stayed the same from 10:16 pm to 10:20 pm is not correct, since the water was draining during the time and thus, water was decreasing.
E) It took 4 minutes for the tub to drain. It is correct since the draining starts at 10:16 pm and ends at 10:20 pm.
Hence the correct statements are B, C and E.

A ball is thrown vertically from the top of a building. The height of the ball after t seconds can be given by the function
Answers
Answer:The instantaneous velocity of the ball after 4 seconds is -0.4 m/s
Step-by-step explanation:
Step-by-step explanation:
If f(x) is the function which represents the distance that a particle moves after x seconds, with velocity v and acceleration a, then
v(x) = f'(x) ⇒ first derivative
a(x) = f"(x) ⇒ second derivative
∵ A ball is thrown vertically from the top of a building
∵ The height of the ball after t seconds can be given by the
function s(t)= -0.1(t -2)² + 10
- To find the function of the velocity differentiate s(t)
∵ s(t) = -0.1(t - 2)² + 10
- Solve the bracket
∵ (t - 2)² = t² - 4t + 4
∴ s(t) = -0.1(t² - 4t + 4) + 10
- Multiply the bracket by -0.1
∴ s(t) = -0.1t² + 0.4t - 0.4 + 10
- Add the like terms
∴ s(t) = -0.1 t² + 0.4t + 9.6
Now let us differentiate s(t)
∵ s'(t) = -0.1(2)t + 0.4(1)
∴ s'(t) = -0.2t + 0.4
- s'(t) is the function of velocity after time t seconds
∵ s'(t) = v(t)
∴ v(t) = -0.2t + 0.4
We need to find the instantaneous velocity of the ball after 4 seconds
Substitute t by 4
∴ v(4) = -0.2(4) + 0.4
∴ v(4) = -0.8 + 0.4
∴ v(4) = -0.4
∴ The v is -0.4 m/s ⇒ -ve means the velocity is downward
The instantaneous velocity of the ball after 4 seconds is -0.4 m/s
Brenda needs to solve the system of linear equations below for her homework assignment. y = 9x – 70 y = 2x – 32 Which is a reasonable estimate of the solution to this system of linear equations?
Answers
Step-by-step explanation:
We have y = 9x - 70 and y = 2x - 32.
=> 9x - 70 = 2x - 32
=> 7x = 38
=> x = 38/7 which is around 5.43.
Answer:
Equations are :--- y = 9x – 70 and y = 2x – 32
Substituting the value of y, we get
[tex]9x - 70 = 2x - 32 \\ 7x = 38 \\ x = \frac{38}{7} \\ \boxed{x = 5.43} \\ y = 9x - 70 \\ y = 9( \frac{38}{7} ) - 70 \\ \boxed{ y = - 21.14}[/tex]

Design An art class is making a mural for their school which has a triangle drawn in the middle. The
length of the bottom of the triangle is x. Another side is 5 more than three times the length of the
bottom of the triangle. The last side is 3 more than the bottom of the triangle. Write and simplify an
expression for the perimeter of the triangle.
What is the expression for the perimeter of the triangle?
(Simplify your answer.)
Answers
Answer:
Expression for perimeter of triangle = 5x+8
Step-by-step explanation:
Given that:
Length of bottom of triangle = b = x
Length of other side = a = 3x + 5
Length of last side = c = x + 3
Perimeter of triangle = a + b + c
Perimeter = (3x+5)+x+(x+3)
Perimeter = 3x+5+x+x+3
Perimeter = 5x + 8
Hence,
Expression for perimeter of triangle = 5x+8
