We can make ratios equivalent to 18:4 by dividing and multiplying on it.
1. (18:4)/2=9:2
2. (18:4)*2=36:8
3. (18:4)*3=54:12
You're welcome :).
Answer:3, 25
Step-by-step explanation:
The seconds should be the x-axis and the height is y axis. Also thinking about how a kicked ball makes an arch, the max is 25, and the mid point between 0 and 6 is 3.
The x-intercept of the graph is (4 , 0)
Step-by-step explanation:
Let us revise the meaning of x-intercept and y-intercept
- x-intercept means value x when y = 0
- That means the graph intersects x-axis at point (a , 0), where a the value of x when y = 0
- y-intercept means value of y when x = 0
- That means the graph intersects y-axis at point (0 , b), where b is the value of y when x = 0
∵ 5x - 4y = 20 is the equation of the graph
- To find x-intercept substitute y by 0
∵ y = 0
∴ 5x - 4(0) = 20
∴ 5x - 0 = 20
∴ 5x = 20
- Divide both sides by 5
∴ x = 4
The x-intercept of the graph is (4 , 0)

Answer:
<u>Story</u>
Jane is 1.7 m tall. She stands 250 m away from the base of the Eiffel tower and looks up at the top of the building. The angle of elevation from her eyeline to the top of the building is 45°.
<u>Question</u>
Calculate an estimate of the height of the building. Give your answer to the nearest meter.
<u>Calculation</u>
Label the sides of the triangle O, A and H (where O is the side opposite to the angle, A is the side adjacent to the angle and H is the hypotenuse).
In the triangle, the angle and side A is known, and O must be calculated.
Therefore, use the trig ratio tan(x) = O/A:
⇒ tan(40) = O/250
⇒ 250tan(40) = O
⇒ O = 209.7749078...
Assume Jane's eye-level is approximately 1.5 m above the ground.
Therefore, the Eiffel tower is approximately:
209.7749078... + 1.5 = 211.2749078.. meters tall
Rounding to the nearest meter ⇒ 211 m
