If s(f) = x-7 and t(x) = 4x^2-x+3, which expression is equivalent to (t•s)(x)

sertanlavr [38]

Answer:

$t(s(x)) = 4x^2 -15x +59$

Step-by-step explanation:

The expression (t•s)(x) means t(s(x)) or t of s of x. It means to substitute s(x) into the equation for t(x).

$t(s(x)) = 4(x-7)^2 -(x-7) + 3\\t(s(x)) = 4(x^2-14x+49) - x + 7 + 3\\t(s(x)) = 4x^2 - 14x + 49 - x + 10\\t(s(x)) = 4x^2 -15x +59$

A circle has the equation 2x2+12x+2y2−16y−150=0.

astra-53 [7]

Answer:

Step-by-step explanation:

hello :

2x²+12x+2y²−16y−150=0

divide by 2 : (x²+6x)+(y²-8y)-75 =0

(x²+6x+9)-9+(y²-8y+16)-16-75 =0

(x+3)²+(y-4)² =10²

The coordinates of the center are (−3,4), and the length of the radius is 10 units.

Answer:

Step-by-step explanation:

Step 1

we know that sinθ = opp/hyp

let x = hyp

sin(23.64) = 5.42/x

0.40=5.42/x

x0.40 = 5.42

x = 13.55

Thefore the length of the hypothenuse is 13.55 Send Love:333
