I got 70

Combination=n!/((n-r)!r!)

=8!/((8-4)!*4!)

=8*7*6*5*4!/(4!*4!)

=8*7*6*5/(4*3*2)

=70 ways

Whats the vertex form of y=x^2-20x+15

Sveta_85 [38]

This looks like a parabola so:
y=x^2 - 20x + 15 --> x^2 - 20x +15=y
(x^2 -20x)=y - 15 --> (x - 10)^2=y - 15 +100 ( used complete the square)
(x - 10)^2=y + 85

Answer:

$\huge\boxed{\sf x = 55\°}$

Step-by-step explanation:

When a quadrilateral is inscribed in a circle, the opposite angles of it add up to 180 degrees.

Here,

∠DCB + ∠DAB = 180 (Opposite angles of a quad inscribed in a circle.)

<u>Given that:</u> ∠DCB = 135° and ∠DAB = x

135 + x = 180

Subtract 135 to both sides

x = 180 - 135

x = 55°

$\rule[225]{225}{2}$

Hope this helped!

What is the antiderivative of secx-tanx

Ivenika [448]

Step-by-step explanation:

∫ (sec x − tan x) dx

∫ sec x dx + ∫ -tan x dx

∫ (sec²x + sec x tan x) / (sec x + tan x) dx + ∫ (-sin x / cos x) dx

ln(sec x + tan x) + ln(cos x) + C
