Hey there!

Solve using pythagoras theorem (it's given that is triangle is right angled. Pythagoras theorem only works in the case of right triangles) ⇨ Hypotenuse² = Base² + Altitude ²

Here,

Base = 9 mm

Hypotenuse = 15 mm

Altitude = b

Hypotenuse² = Base² + Altitude ²

15² = 9² + b²

225 = 81 + b²

225 - 81 = b²

144 = b²

√144 = b

12 mm = b

Hope it helps ya!

The cows at the farm eat 5 3/5 hay everyday.The horses eat 1 5/6 as much as the cows. How bales of hay are the horses fed each d

Marina86 [1]

Answer:

13 2/9

Step-by-step explanation:

Cows eats=5 3/5 Hays everyday

Horses eats=1 5/6 as much as the cow

=1 5/6 of what the cow eat+5 3/5

=1 5/6 × 5 3/5 + 5 3/5

=11/6×28/6+28/6

= 308/36+28/6

=308+168/36

=476/36

=13 8/36

=13 2/9

Given point A (3, 8) and point B (-5, 1). Find the following: a.) The coordinates of the midpoint of segment AB. Write your answ

ss7ja [257]

Answer:

Mid point:

$= ( \frac{3 + - 5}{2} , \: \frac{1 + 8}{2} ) \\ = ( - 1, \: 4.5)$

distance:

$= \sqrt{ {( - 5 - 3)}^{2} + {(1 - 8)}^{2} } \\ = \sqrt{64 + 49} \\ = \sqrt{113} \\ = 10.6 \: units$

slope:

$= \frac{1 - 8}{ - 5 - 3} \\ = \frac{ - 7}{ - 8} \\ = \frac{7}{8}$

What is the discrimination of the quadratic equation 8x^2-2x-1=0

ELEN [110]

$D=b^2-4ac\\D=(-2)^2-4(8)(-1)\\D=4+32\\D=36$

For another information, when D > 0, there are 2 real roots.

When D = 0, there is only one real root.

And when D < 0, there are no real roots (also known as imaginary.)
