Answer:

x = 25

Step-by-step explanation:

Here's my work. Basically, I knew that the x in angle A is alternate interior to angle C, so they would both be x. the 50 degrees is one a 180 degree line, so the inside of the triangle DCB is 130. X must equal x, so they would both be 25 degrees.

Answer:

A. $200.96 \: {ft}^{2}$

Step-by-step explanation:

Corral is circular in shape.

Radius of the corral would be be the distance from the post to the edge of the corral.

-> r = 8 ft

$A(grass\: eaten) = \pi {r}^{2} \\ \\ = 3.14 {(8)}^{2} \\ \\ = 200.96 \: {ft}^{2}$

The curve with equation y=ax^2+bx has a gradient of 3 at the point (2,-2). Find the values of a and b.

Airida [17]

Answer:

a = 2, b = - 5

Step-by-step explanation:

Given

y = ax² + bx

$\frac{dy}{dx}$ is the measure of the slope at x = a

Differentiate each term with respect to x using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

$\frac{dy}{dx}$ = 2ax + b, hence

2ax + b = 3 at (2, - 2)

Substitute x = 2 into $\frac{dy}{dx}$

4a + b = 3 → (1) and substitute x = 2 into y

4a + 2b = - 2 → (2)

Subtract ( 1) from (2)

b = - 2 - 3 = - 5

Substitute b = - 5 into (1)

4a - 5 = 3 ( add 5 to both sides )

4a = 8 ( divide both sides by 4 )

a = 2
