The graph shows the movement of a car from point A to point D, there are two slant line AB and CD.
(1) Calculate the speed of the car during the first 10 seconds.
(2) For how long did the car stop.
(3) What is the average speed of the car for the whole journey.
(4) Why the line BC is flat not slant.
Answer:
The answer is below
Step-by-step explanation:
a) The speed of the car during the first 10 seconds is equal to the slope of the line AB. The line AB passes through (0, 0) and (10, 200)
slope = (200 - 0)/(10 - 0) = 20 m/s
The speed of the car during the first 10 seconds is 20 m/s
b) The time for the car to move from point A to point D = 60 seconds
c) Distance from point A to B = 200 m, distance from C to D = 500 - 200 = 300 m, distance from B to C = 20 m/s * 20 s = 400 m
Total distance from A to D = 200 + 400 + 300 = 900 m
Average speed = total distance / total time = 900 m / 60 seconds = 15 m/s
d) line BC is flat because the car moves at a constant speed from point B to point C. That is the speed does not change.

Si se invierten $ 500 a una tasa de 5% anual. Hallar el valor futuro a 3 años si el interés es compuesto trimestralmente.
Answer:
the future value is $5800.38
Step-by-step explanation:
Given that
The invested amount i.e present value is $500
The rate is 5 % per year so quarterly rate is 5% ÷ 4 = 1.25%
The time period is 3 per year so for quartely it is 3 × 4 = 12
We need to find out the future value
So as we know that
Future value = Present value × (1 + rate of interest)^time
= $500 × (1 + 0.0125)^12
= $580.38
hence, the future value is $5800.38
Which set of angles could be the interior angles of a triangle?
A. 109, 20°, and 60°
B. 20°, 20°, and 50°
C. 20°, 30°, and 50°
D. 20°, 60°, and 100°
Answer:
D. 20°, 60°, and 100°
Step-by-step explanation:
basically you're testing which set adds up to 180°:
D should immediately catch the eye since it has a simple 100°, and 60+20 is 80, making D the correct answer
a: 189°
b: 90°
c: 120°
d: 180°

For which value of x is the row in the table of values incorrect? The function is the quadratic function y equals the quantity 3 divided by 4 end of quantity multiplied by x squared.
A. x = 3
B. x = 2
C. x = 0
D. x = 5
Answer:
B. x = 2
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
check by substituting each given value of x into the function
x = 0 ⇒ y = × 0² = 0
hence (0, 0) is correct
x = 2 ⇒ y = × 4 = 3
hence (2, 4 ) is incorrect
x = 3 ⇒ y = × 9 = 6
hence (3, 6 ) is correct
x = 5 ⇒ y = × 25 = 18
hence (5, 18 ) is correct

Cameron has 6 pounds of pears.
A roasted-pears recipe requires
13 pounds of pears.
How many batches can he make?
Number sentence:
Solution:
Answer:
See explanation
Step-by-step explanation:
Pears Cameron has = 6 pounds
roasted-pears recipe per batch = 13 pounds
How many batches can he make?
Number of batches of roasted-pear = Pears Cameron has / roasted-pears recipe per batch
= 6 pounds / 13 pounds
= 0.4615384615384 pounds
Approximately,
Number of batches of roasted-pear = 0.46 pounds

–––––––––☆–––––––––what is the area???!?!?!
9514 1404 393
Answer:
ac
Step-by-step explanation:
The length of the base is the x-distance between E and H, so is ...
base = a - 0 = a
The height is the y-distance between E and F, so is ...
height = c - 0 = c
The area of the parallelogram is the product of base and height.
A = base×height
A = a×c
The area of the parallelogram is ac.
Which expression represents the area of this shape?
Answer:
(2x2)+(2x6)
Step-by-step explanation:
area= length x breathe
= (2x2) + (2x6)

In a group of 120 recruits at the police academy 80 are college graduates and 25 are army veterans. If 15 of the recruits are both college graduate and army veterans as shown above, how many are neither college graduate nor army veterans?
Answer:
the number of recruits neither be college graduate and nor army veterans is 30
Step-by-step explanation:
The computation of the number of recruits neither be college graduate and nor army veterans is as follows;
= Total recruits - (college students + army veterans - both college graduates & army veterans)
= 120 recruits - (80 + 25 - 15)
= 120 recruits - 90
= 30
hence, the number of recruits neither be college graduate and nor army veterans is 30
Find the value of y !!
Answer:
y ≈18.8
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
y^2 +18^2 = 26^2
y^2 +324=676
y^2 = 676-324
y^2 =352
Taking the square root of each side
sqrt(y^2) = sqrt(352)
y is approximately 18.76
y ≈18.8
