Answer:

Step-by-step explanation:

The enclosing rectangle is 24 units long and 12 units high. Its area is ...

(24 units)(12 units) = 288 square units

The white circles obviously cover more than half the area, so the only viable answer choice is 62.

If you want to go to the trouble to actually figure it out, you can find the area of each circle using the area formula ...

A = πr² = (3.14)(6²) = 113.04

Then both circles have an area of 2×113.04 = 226.08, and the shaded area is the difference between that and the rectangle area:

shaded area = 288 -226.08 = 61.92 ≈ 62

Answer:

x2 = -0.600000

x3 = -0.521600

Step-by-step explanation:

Given the formula;

xn+1 = (xn)³-5/10

x2 = (x1)³-5/10

Given x1 = -1

x2 = (-1)³-5/10

x2 = (-1-5)/10

x2 = -6/10

x2 = -0.600000

x3 = (x3)³-5/10

Given x3 = -0.6

x3 = (-0.6)³-5/10

x3 = (-0.216-5)/10

x3 = -5.216/10

x3 = -0.521600

Which calculation could not be used to find the percentage change

bogdanovich [222]

Answer:

Option (B).

Step-by-step explanation:

Percentage change between two numbers a and b can be calculated by the formula,

% change = $\frac{|b-a|}{a}\times 100$

Where, (b - a) = Change in values

a = Initial value

If a = 16 and b = 20

Percentage change between 16 and 20 will be,

= $(\frac{20-16}{16})\times 100$

= $\frac{4}{16}\times 100$

= 25%

If a = 20 and b = 16,

Percentage change = $\frac{|16-20|}{20}\times 100$

= 20%

Therefore, %change between 16 and 24 may be 16% or 20%.

Option (A),

$\frac{20-16}{16}\times 100$ = 25%

Option (B),

$\frac{20}{16}-1\times 100$ = 1.25 - 1 × 100

= 1.25 - 100

= -98.75%

Option (C),

$100\times \frac{1}{4}$ = 25%

Option (D),

$\frac{(20-16)}{20}\times 100$ = 20%

Therefore, we can not use the calculation used in Option (B).

What equation is being graphed?

Alex

Answer:

D. y-4= -3/2(x+5)

Step-by-step explanation:

Firstly, taking two valid ordered pairs from the graph:

(-2,4) and (2,-2)

Using Delta y over Delta x, we are able to obtain m as -3/2

Next,

The following is the point-slope formula:

y-y₁=m(x-x₁)

Based on the graph, (4,-5) can be spotted as a definite ordered pair

Therefore, y-4= -3/2(x+5) fits the graph best and has the appropriate m value.
