Answer:

The number of space shuttle launches the greatest in the year 1985 (C)

Step-by-step Explanation:

According to the graph given in the attachment, the no. of launches made in those years are:

1981: 2
1982: 3
1983: 4
1984: 5
1985: 9
1986: 6

The no. of launches was greatest in the year 1985 and the line graph touches the highest peak in 1985 $.$

Select Exponential growth or Exponential decay for each function.

Lena [83]

Answer:

f(x)=(1.023) ⋅ 3^x Growth

f(x)=3 ⋅ (0.072)^x Decay

f(x)=4 ⋅ (0.035)^x Decay

f(x)=2 ⋅ (1.34)^x Growth

Step-by-step explanation:

An exponential function at its heart has a base number of rate. If the rate is less than 1, then the function decays. If the base number or rate is greater than 1, then the function grows and increase.

f(x)=(1.023) ⋅ 3^x Rate 3 - Growth

f(x)=3 ⋅ (0.072)^x Rate 0.072 - Decay

f(x)=4 ⋅ (0.035)^x Rate 0.035 - Decay

f(x)=2 ⋅ (1.34)^x Rate 1.34 - Growth

A box holds 42 pieces of red construction paper and 18 pieces of blue construction paper. A piece of paper is pulled out of the

dimulka [17.4K]

First problem :
probability to draw a red paper : 42/(42+18)=7/10

In 110 tries one can thus expect to draw 7/10*110=77 red papers

Second problem :
Since for 150 trials (which will give the least error) we have got 135 yellow balls, we can expect twice as much in 300=150*2 trials, which makes 270 yellow balls.

HELP PLEASE!!!!!! Only 5 more minutes till i turn it in!!!

GarryVolchara [31]

Answer:

<B = 70°

Step-by-step explanation:

First we need to find x, lets plugin these two equations.

2x - 30 = x + 20

Then find like terms

2x = x + 50 =

x = 50

Then we plugin 50 for x

2(50) - 30 =

100 - 30 = 70

<B = 70°

The Oriental Pearl Tower in Shanghai, China, is a 468-meter high tower with 11 spheres along the tower. Two spheres are larger t

Alexeev081 [22]

The approximate total volume of the two largest spheres on the Oriental Pearl Tower 113105.45 m³.

<h3 /><h3>How to find the volume of a sphere</h3>

The volume of the sphere is calculated as follows:

volume = 4 / 3 πr³

where

r = radius

The lower two larger spheres in the tower has a radius of 25 meters and 22.5 meters. Therefore, the total volume of the two largest sphere is as follows:

volume of lower sphere = 4 / 3 × 3.14 × 25³

volume of lower sphere = 196250 / 3

volume of lower sphere = 65416.6666667

volume of lower sphere = 65416.7 m³

volume of higher sphere = 4 / 3 × 3.14 × 22.5³

volume of higher sphere = 143066.25 / 3

volume of higher sphere = 47688.75

volume of higher sphere = 47688.8 m³

The approximate total volume = 65416.7 + 47688.8 = 113105.45 m³
