Answer:
£60
Step-by-step explanation:
Let the original cost be x.
x × (1 - 20%) = 48
0.8x = 48
x = 48/0.8
x = 60
The original cost was £60 before the sale.
Answer:
No. The ladder is too steep.
Step-by-step explanation:
Length of ladder = 17 feet. This is the hypotenuse.
Side a of a right triangle = 16.6
To answer this, you need one of the trigonometric functions.
Opposite = 16.5
hypotenuse = 17
The function you need is the sine function.
Sin(theta) = opposite / hypotenuse
sin(theta) = 16.5 / 17
Sin(theta) = 0.97059
theta = sin-1(0.07059)
theta = 76.07
No the ladder is too steep.
Answer:
Step-by-step explanation:
What the questionmeant is :
- what are the values that are within the function . In other words what are the values that the function work with
let's see :
- The function is a line
- in the graph each unit represent 2 beacuse we used 5 units the represent 10 : 10/5=2
Let's try each value :
- -1 ; yes the function reaches -1
- 1 ; yes the same
- 0; yes it works
- -4 ; no it doesn't work since the function ends before reaching it
- 6; no the same it doesn't work
- 2; yes works
