Answer:

Surface area of sphere = 4πr²

r = radius

radius = diameter /2

= 12/2

= 6units

Surface area = 4π×6²

= 144π

= 452.4 square units

Solve the system of equation

kherson [118]

Answer:

The answer to your question is:

x = -10; y = 8

Step-by-step explanation:

Solve equations by elimination method

2x + 3y = 4 (1)

x + 2y = 6 (2)

Multiply 2 by -2

2x + 3y = 4

-2x - 4y = -12

-y = -8

y = 8

Substitute y in (2)

x + 2(8) = 6

x = 6 - 16

x = -10

Determine the amplitude or period as requested . Amplitude of y = - 1/5 * sin x a - 1/5 1/5 b 5 d. pi/5

Brrunno [24]

Answer:

The amplitude is 1/5

Step-by-step explanation:

Given

$y = -\frac{1}{5}\sin(x)$

Required

Determine the amplitude

The general cosine function is:

$y = A\sin(k(x + c)) +d$

Where

$Amplitude = |A|$

Compare $y = A\sin(k(x + c)) +d$ and $y = -\frac{1}{5}\sin(x)$

$A = -\frac{1}{5}$

So:

$Amplitude = |-\frac{1}{5}|$

$Amplitude = \frac{1}{5}$

How would you determine what fraction strips with rhe same denominator would fit exactly under 1/2 & 1/3. What are they?

vfiekz [6]

Step-by-step explanation:

$\frac{1}{2} = \frac{1 \times 3}{2 \times 3} = \frac{1}{6} \\ \\ \frac{1}{3} = \frac{1 \times 2}{3 \times 2} = \frac{1}{6}$

${ \boxed{{ \bold{{ \pink{e}}{ \blue{x}}{ \purple{p}}{ \green{l}}{ \red{a}}n{ \purple{a}}{ \orange{t}}{ \red{i}}on}}}}$

we equate first under the fraction (denominator)
find the number of products that allow the denominators to be the same
the result that both fractions have the same denominator
