Situation:
A geologist in South America discovers a
bird skeleton that contains 47% of its
original amount of C-14.
N = Noekt
No = inital amount of C-14 (at time
t = 0)
N = amount of C-14 at time t
k= 0.0001
t = time, in years

Find the age of the bird skeleton to the nearest year.

Step-by-step explanation:

The x-intercept is the point at which the graph crosses the x-axis.

Answer:

460

Step-by-step explanation:

If 207 students are going to college means that 207 are the 45% of the students that are going to college we need the total number of students that were in the graduating class so,

[tex]Total Students=\frac{207}{0.45} \\\\Total Students=460[/tex]

So there are 460 students in the graduating class and 45% of them are going to college which is 207

Answer:

Step-by-step explanation:

when a line is perpendicular to a given line, it uses the opposite reciprocal of the slope (basically flip the top and bottom numbers of the slope fraction and then change its sign from negative to positive or vice versa)

the slope of the given line is 1/4

the opposite would be -1/4

the reciprocal would be -4/1 or just -4

so the slope of this new line is -4

what we know so far is

y = -4x + b

since it has to go through point P (9, -2)

we’ll substitute 9 for x and -2 for y to find b

-2 = -4(9) + b

-2 = -36 + b

34 = b

so the final equation is

y = 4x + 34

Answer:

x=27

Step-by-step explanation:

since lime m is parralell to line n, that means adjacent angles are equal to each other x and 27 are adjacent because they are across from each other basically. therefore, x is equal to 27 degrees.

Answer:

Answer:

[tex]x\leq 4[/tex]

Step-by-step explanation:

525 = 175 + 85x

350 = 85x

x about 4.11, so [tex]x\leq 4[/tex]

This means that Jamal can grow no more than 4 trees.

Answer:

Length is 8feet

Width is 26feet

Step-by-step explanation:

Area of the garden = Length × Width

A = LW

Perimeter = 2(L+W)

If the length of the garden is 8 feet more than 3 times the width, then;

L = 3W+8

Substitute into the second equation

P =2(L+W)

P = 2(3W+8+W)

P = 2(4W+8)

P = 2(4W)+16

If he needs 64 feet of fencing to do the job then;

64 = 8w+16

8w = 64-16

8w = 48

w = 48/8

w = 6feet

Hence the width is 6feet

Get the length

L = 3w+8

L = 3(6)+8

L =18+8

L = 26

Hence the length is 26feet

Answer:

440 million computer sold

Step-by-step explanation:

in 2010 = 20 million sold

in 2011 = 4.5*20= 90 million sold

by linear equation formula

[tex]\frac{x-x_1}{x_2-x_1}=\frac{y-y_1}{y_2-y_1}[/tex]

where y = computer sold in million

x=  year

putting in above equation and solving we get

\frac{x-10}{11-10}=\frac{y-20}{90-20}

70x-y=680

in 2016 put x= 16 ( assuming hat the sales follow a linear trend through 2016)

y = 70*16-680 = 1120-680= 440 million computer sold

Answer:

C)3m +7 27 and -4m +85 – 12

Step-by-step explanation:

Answer:

125

Step-by-step explanation:

For arithmetic sequence: aₙ = a₁ + (n-1)d       Sₙ = n/2 * (a₁ + aₙ)

a1+a4+a7+a10 = a₁ + (a₁ + 3d) + (a₁ + 6d) + (a₁ + 9d) = 4a₁ + 18d = 2 * (2a₁ + 9d)

2 * (2a₁ + 9d) = 50

2a₁ + 9d = 25

a1+a2+a3...+a10 = 10/2 * (a₁ + a₁₀) = 5 * (a₁ + a₁ + 9d) = 5 * (2a₁ + 9d)

a1+a2+a3...+a10 = 5 * 25 = 125

Answer:

b, c and d

Step-by-step explanation:

Answer:

x = 5

Step-by-step explanation:

25 = 6x - 5 (add 5 on both sides)

+5         +5

30 = 6x (divide by 6 on both sides)

5 = x

Answer:

The value is  [tex]P(X = 3) = 0.1804[/tex]  

Step-by-step explanation:

From the question we are told that

   The number of customer that enter the tellers every 5 minutes is  [tex]\lambda = 2[/tex]

Generally the  probability that exactly three customers enter the queue in a randomly selected five-minute period is mathematically represented as

      [tex]P(X = 3) = \frac{e^{- \lambda} * \lambda^{3}}{3!}[/tex]

=>   [tex]P(X = 3) = \frac{e^{- 2} * \lambda^{3}}{3!}[/tex]

=>   [tex]P(X = 3) = 0.1804[/tex]
