Plot the line for the equation on thr graph. y-2=-2(x+4)​
julia-pushkina [17]

Answer:

see attached

Step-by-step explanation:

y-2=-2(x+4)​

y -2 = x(-2) + 4(-2)

y -2 = -2x - 8

y = -2x - 8 + 2

y = -2x - 6

When  x = 0, y = -6. Hence (0,-6) is a point on the line

when y = 0, x = -3. Hence (-3,0) is a point on the line.

Plot these 2 points and connect with a line (see attached)

compare the two numbers to find which is greater. explain how you can compare them without writing them in standard notation fir
Anna71 [15]

The number with the largest exponent is the largest value overall. In this case, that would be 2.1 x 10^8 which is the largest value since 8 is the largest exponent.

Note: The number 4.5 x 10^6 is the number 4.5 million, while the number 2.1 x 10^8 is the number 210 million. The positive exponent means "move the decimal point that number of times to the right". So 4.5 x 10^6 means "move the decimal point 6 spots to the right" so you can convert to standard form. The larger the exponent, the more places the decimal point moves to the right.

What is the volume of a hemisphere with a radius of 9.2 cm, rounded to the nearest tenth of a cubic centimeter?
NARA [144]

Answer:

volume of the hemisphere   ≈1577.5 cm³

Step-by-step explanation:

To find the formula for calculating the volume of a hemisphere, we will follow the steps below:

write the formula for calculating the volume of a hemisphere.

volume of a hemisphere = volume of a sphere ÷2

                                        = \frac{4}{3}πr³   ÷   2

                                        =\frac{2}{3} πr³

WHERE r is the radius

from the question given, radius= 9.2 cm  

π is a constant and is ≈ 3.14

we can now proceed to insert the values into the equation

volume of a hemisphere =  \frac{2}{3} πr³

                                          = \frac{2}{3} × 3.14 ×9.2³

                                           = \frac{2}{3} × 3.14 ×753.571

                                          ≈1577.5 cm³   to the nearest tenth of cubic centimeter

volume of the hemisphere   ≈1577.5 cm³
