Answer:
24 cm
Step-by-step explanation:
The altitude from the centre to the chord is 5 cm and bisects the chord.
The radius of the circle is 26 cm ÷ 2 = 13 cm
There is a right triangle formed with legs 5 and x ( x is half the chord )
The hypotenuse is the radius, then using Pythagoras' identity
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take the square root of both sides )
x =
= 12
Then
length of chord = 2x = 2 × 12 = 24 cm
Answer:
it should be 3x^2 +2
Step-by-step explanation:
If it was the exact spending as the previous year it would be $520 but doubled would be $1,040. Since there is not enough information in the problem I can not say for certain.
Square roots and squaring are always nonlinear.
Answer:
A) 5k
Step-by-step explanation:
anything near a number like that is usually times. Like 7g would be 7xg!
