HELPPPPP! WILL Give BRAINLIEST! 100 POINTS! Please get it correct!

Leno4ka [110]

Answer:

11.26 cm²

Step-by-step explanation:

The shaded region is the difference of areas of semicircle AB and triangle ABC.

ABC is right triangle as AB is diameter, so C is right angle.

Area of semicircle:

A = 1/2πr² = 1/2*3.14*4² = 25.12 cm²

Area of triangle:

A = 1/2BC*AC = 1/2*4* $\sqrt{8^2-4^2}$ = 2 $\sqrt{48}$ = 13.86 cm²

Shaded are is:

25.12 - 13.86 = 11.26 cm²

The function p(x) is an odd degree polynomial with a negative leading coefficient. If q(x) = x3 + 5x2 - 9x - 45, which statement

saul85 [17]

Answer:

As x approaches negative infinity, p(x) approaches positive infinity and q(x) approaches negative infinity.

Step-by-step explanation:

The order of the polynomial and the sign of the leading coefficient will let us find the correct answer easily,

If you get a negative number (such as negative infinity) and you take it to an odd power, (for example 3), you will still get a negative number.

As q(x) has a positive leading coefficient, this means that as x approaches negative infinity, q(x) will approach too negative infinity.

Since p(x) has an odd degree, but negative leading coefficient,

(-)*(-) = +

And this means that p(x) approaches positive infinity

Find the zeros of the quadratic function: y= 6(7x + 9)(8x - 3).

fiasKO [112]

Answer:

A) (-9/7,0), (3/8,0)

Step-by-step explanation:

Zeros of a quadratic function:

x for which y = 0.

In this question:

$y = 6(7x + 9)(8x - 3)$

It's 0 if one of the factors is 0. 6 is never 0, now about the other to:

$7x + 9 = 0$

$7x = -9$

$x = -\frac{9}{7}$

So (-9/7, 0) is a zero of the quadratic function.

The other is:

$8x - 3 = 0$

$8x = 3$

$x = \frac{3}{8}$

(3/8,0) is the other zero.

Thus, the correct answer is given by option A.
