Answer:
x ≈ 3.1 ft
Step-by-step explanation:
The segment from the centre to the chord is a perpendicular bisector, thus
The triangle is right with base =
x
Applying Pythagoras' identity to the right triangle, then
(
x )² + 1.4² = 2.1²
x² + 1.96 = 4.41 ( subtract 1.96 from both sides )
x² = 2.45 ( multiply both sides by 4 )
x² = 9.8 ( take the square root of both sides )
x =
≈ 3.1 ft ( to the nearest tenth )
Slope formula: (y2 - y1/x2 - x1)
Substitute
(9 - 17/-1 - 3) = 2
Answer:
-750
Step-by-step explanation:
Q(h)=-8h^2-5h ,
Let x = -10
q(-10) = -8 (-10)^2 -5(-10)
=-8 *100 +50
=-800+50
= -750
Answer:
Im pretty sure the answer in $8.70
Step-by-step explanation:
All you have to do is 382 divided by 44
Hey there!!
Let us take the first number as ' x '
According to the question
The second number exceeds the first number by 15
hence, the second number = x+15
The sum of both the numbers = 69
which means
x + x + 15 = 69
2x+15 = 69
Subtracting by 15 on both sides
2x + 15 - 15 = 69 - 15
2x = 54
dividing by 2 on both sides
x = 27
first number = 27
second number = 27 + 15
= 42
Hope my answer helps!
