Step-by-step explanation:

As we can see it a right angled triangle

so <y =90°

Now

3x + 11° + 25° + 90° = 180°{being sum of angles of triangle}

3x + 126° = 180°

3x = 54°

X = 18°

What are the coordinates of the turning point for the function f(x) = (x - 1)3 - 3? A. (-1, -3)

Naddik [55]

ANSWER

The turning point is

$(1,-3).$

EXPLANATION

The function given to us is

$f(x) = (x - 1) ^{3} - 3$

At turning point,
$f '(x) = 0$

So we need to differentiate the given function and equate it to zero.

We using the chain rule of differentiation, we obtain,
$f '(x) =3 (x - 1) ^{2}$

We equate this to zero to obtain,

$3 (x - 1) ^{2} = 0$

We divide through by 3.

$(x - 1) ^{2} = 0$

We solve for x to get,

$x - 1 = 0$

$x = 1$

We substitute this x-value in to the function to obtain the corresponding y-value of the turning point.

$f(1) = (1- 1) ^{3} - 3$

$f(1) = 0 - 3$

$f(1) = - 3$

Therefore the turning point is

$(1,-3)$

C is the correct answer.

A french fry stand at the fair serves their fries in paper cones. The cones have a radius of 2 inches and a height of 6 inches.

stellarik [79]

The formula for the volume of a right circular cone is V = $\pi r^{2} h$ . In solving for the volume of the first french fries cones V = $\pi ( 2^{2} )(6)$ = 75.398 $in^{3}$ . In solving for the height of the second french fries cones with a new radius of 4, the formula is rearranged to h = $\frac{V}{ \pi r^{2} }$ = $\frac{75.398}{ \pi (4^{2}) }$ = 1.5 in or inches. The height of the new cones will be 1.5 inches.

d1i1m1o1n [39]

Answer: to move a graph up c units, add c to the whole function

so basicaly what you did is you subtraced 3 from the whole function

the whole graph shifts 3 units down
