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:x<-7
Step-by-step explanation:
3x -15x - 30 > 54
-12x-30>54
-12x<54+30
I moved 30 from left side to right which becomes positive and > becomes <
-12x<84
-12x/-12<84/-12 I used my calculator to do this
x<-7
has characteristic equation
which has roots at
. The negative root has multiplicity 2. So the general solution is
<h2>
Answer:</h2>
<u>The length is</u><u> 12 feet</u>
<h2>
Step-by-step explanation:</h2>
The width of the garden is 5 feet
After that the total edging is telling us the area
We know that
<h3>Area of rectangle = length x width</h3>
So
60 = length x 5
Length = 60 / 5
Length = 12 feet
Answer:
466
Step-by-step explanation:
50 + 8*52 = 466
