Answer: -7g = k
explanation: -7 is the opposite of 7
Right on top of 'a'. They'll look like one single point on the number line.
Answer:
h(f(x))=3x-4
Step-by-step explanation:
You combine both F(X) and H(x).
f(x)=x-7 , therefore it is f(x)=1x-7
You add 2x with 1x to get 3x
and 7-3 is -4.
h(f(x))=3x-4

Answer:
4.4 inches
Step-by-step explanation:
Here, we are interested in calculating the value of x.
Mathematically, a line that comes from the center of the circle and extends to a chord, divides the chord into two equal parts.
This means what we have is a right angled triangle with the radius being the hypotenuse, the half of the length of the chord as the other side of the triangle.
3.7 is half the length of the chord i.e 7.4/2
Thus;
using Pythagoras’ theorem
x^2 = 2.4^2 + 3.7^2
Pythagoras’ posited that the square of the hypotenuse is equal to the sum of the squares of the other two sides of the triangle.
Thus;
x^2 =5.76 + 13.69
x^2 = 19.45
x = √(19.45)
x = 4.41 inches which is 4.4 inches to the nearest tenth
