Answer 180, 260 and 360
Step-by-step explanation
Eli age = 9
Freda age = 13
Geoff age = 18
We write the ages in ratio as 9 : 13 : 18
Now sum all the ages 9 + 13 + 18 = 40
The total amount to be shared is £800
Therefore Eli share = 9/40 x £800 = £180
Freda share = 13/40 x £800 = £260
Geoff share = 18/40 x £800 = £360
Substitute x = -5
|2* -5 -1| + 10
|-10-1| + 10

The ladder makes 79.92 degrees of angle with the ground (Calculation: Cos A = 7/40 = 0.175 resulting A = ACos 0.175 = 79.92 degrees). This problem can be solved by using a simple trigonometry formula of Cosine which stated Cos A = Adjacent/Hypotenuse. The ladder length of 40 feet is the hypotenuse side of the triangle and the 7 feet distance between the ladder's foot and the wall is the adjacent side<span>. </span>
Answer: f(x)=2-x^2
Step-by-step explanation:
The quadratic equation is
y=ax^2+bx+c
and c is equal to the y-intercept.
in the twi graphs shown both have the same shape but different y-intervepts.
c(the y-intercept) in the first graph is 5 and in the second graph(F) is 2.
The answer is -130. hope this helps.
