Answer:

(-5,3)

Step-by-step explanation:

When you reflect over the x axis the numbers will be the same but the sign will change depending on which quadrant you end up in.

(5,3) will reflect over x axis and become (-5,3) and will be in the 2nd quadrant after reflecting.

A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?
m_a_m_a [10]

Answer:

523.3 cubic inches

Step-by-step explanation:

A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?

The shape of a basketball is spherical.

Hence:

The volume of a basketball = 4/3 × π × r³

From the question,

π = 3.14

r = radius = Diameter/2

r = 10 in/2 = 5 in

Hence:

The volume of the basketball

= 4/3 × 3.14 × 5³

= 1570 ÷ 3

= 523.33333333 cubic inches

Therefore, the approximate volume of the basketball = 523.3 cubic inches

The mass of Earth is 5.97 >< 1024 kilograms. The mass of the Moon is 7.34 x 1022 kilograms. What is the combined mass of E
LuckyWell [14K]

Answer:

7.34x10^22 kg can also be written as 0.0734 * 10^24 kg

Since both numbers are * 10^24, you can just add 5.97 + 0.0734 = 6.043. Then you have to add the * 10^24 giving you 6.043 * 10^24 kg

The ratio of Earth / moon is 5.97x10^24 / 7.34x10^22 = 81. The mass of the Earth is 81 times the mass of the moon.

Step-by-step explanation: give me brainliest please :)

Answer:

y = 1500(0.024)^t

Step-by-step explanation:

Given

a = 1500km -- initial area

b = 2.4\% -- rate

t = time --- (years)

Required

Represent as an exponential function

An exponential function has the form:

y = ab^t

Where

a = initial\ value

b = rate and b \ne 1

t= time

Substitute values for a and b, we have:

y = 1500 * (2.4\%)^t

Convert percentage to decimal

y = 1500 * (0.024)^t

y = 1500(0.024)^t

Hence, the exponential function that represents the scenario is: y = 1500(0.024)^t
