Student A is wrong and Student B is correct.

How?

Direction is saying to construct a line that passes through C
The last step is enough to describe that A is wrong.
Its saying to swing an arc(Should be line).
On the other hand Student B has done correct
By passing point through C and G it satisfies our required construction.

Can someone explain the answer and how the formula works?

zubka84 [21]

Answer:

A = 346.185 cm²

Step-by-step explanation:

The formula given is:

A = πr²

A = Area of the object (circle).

π = 3.14

r = radius, which is 1/2 of the diameter, a straight line from one end to the other.

Set the equation, plug in the corresponding numbers to the corresponding variables:

A = (3.14)(10.5)²

Simplify. Remember to follow PEMDAS.

PEMDAS =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

and is the order of operation.

First, solve the exponent.

(10.5)² = 10.5 * 10.5 = 110.25

Next, multiply:

A = (3.14)(110.25)

A = 346.185 cm²

A = 346.185 cm² is your answer.

NeX [460]

Answer:

{chocolate, strawberries, peanuts}

Step-by-step explanation:

Given that three sets are

Let A = {vanilla, chocolate, hot fudge, strawberries, sprinkles, peanuts, whipped cream}

Let B = {vanilla, hot fudge, sprinkles, whipped cream}

Let C = {chocolate, hot fudge, peanuts, whipped cream}

Then Universal set U = AUBUC

= {vanilla, chocolate, hot fudge, strawberries, sprinkles, peanuts, whipped cream}

B'=elements in U but not in B

={chocolate, strawberries, peanuts}

choose the equation below that represents the line passing through the point (2, −4) with a slope of one half. a. y = 1/2x 5 b.

ICE Princess25 [194]

The point-slope form: $y-y_0=m(x-x_0)$

$m=\dfrac{1}{2};\ (2;-4)\to x_0=2;\ y_0=-4$

subtitute

$y-(-4)=\dfrac{1}{2}(x-2)\\\\\boxed{y+4=\frac{1}{2}(x-2)}$
