Answer:

B) 12.25πm²  

Step-by-step explanation:

The formula for the <em>circumference</em> of a circle is

C = 2πr

The circumference of your circle is

C = 7πm

If we factor out a 2 from the 7, we get

C = (2 × 3.5)πm = 2π(3.5m)

Now, if we compare the two formulas, we see that

r = 3.5m

The formula for the <em>area</em> of a circle is

A = πr²

If r = 3.5m, then the area of your circle is

A = π(3.5m)² = 12.25πm²

Solve the equation by completing the square. Round to the nearest hundredth if necessary? X^2+3x=24
Genrish500 [490]
X^2+3x=24, halve the linear coefficient, square it, and add it to both sides

In this case (3/2)^2=2.25

x^2+3x+2.25=26.25 now the left side is a perfect square...

(x+1.5)^2=26.25  take the square root of both sides

x+1.5=±√26.25  subtract 1.5 from both sides

x=-1.5±√26.25

x=-1.5-√26.25 and -1.5+√26.25

x≈ -6.62 and 3.62

Four minus x equals negative two. 4 - x = -2. whats x?
Roman55 [17]

Answer:

X would have to equal 6. To work it out, you subtract 4 from each side to cancel out the 4. -x = -6. You have to make -x just x so you × each side by -1. You get x = 6.

If the probability is 0.54 that Stock A will increase in value during the next month and the probability is 0.68 that Stock B wi
Aloiza [94]

P(A) =0.54

P(B)= 0.68

P'(A)= 1-0.54 = 0.46

P'(B)= 1- 0.68 = 0.32

The probability of neither of both event will occur:

= P'(A)×P'(B)

=0.46 × 0.32

=0.1472

Find the measure of
koban [17]

Answer:

m∡GHI = 21°

Step-by-step explanation:

Since the lines are intersecting, GHI and JHK are opposite angles, so they are the same measure.

That means you can set them equal to each other

x + 7 = 3x - 21

x = 14

Now plug x into GHI

14 + 7 = 21

m∡GHI = 21°
