The population of a heard of cattle numbered was 5000 to begin with and was 10,000 after 10 years. If the population was growing

Lapatulllka [165]

Answer:

$r=0.0718$ . The closest value from your given choices is C)r=0.69

Step-by-step explanation:

To solve this we are using the standard exponential growth equation:

$f(t)=A(1+r)^t$

where

$f(t)$ is the final population after $t$ years

$A$ is the initial population

$r$ is the growth rate in decimal form

$t$ is the time in years

We know from our problem that the initial population is 5000, the final population is 10000, and the time is 10 years, so $A=5000$ , $f(t)=10000$ , and $t=10$ .

Let's replace the values and solve for $r$ :

$f(t)=A(1+r)^t$

$10000=5000(1+r)^{10}$

Divide both sides by 5000

$\frac{10000}{5000} =(1+r)^{10}$

$2=(1+r)^{10}$

Take root of 10 to both sides

$\sqrt[10]{2} =\sqrt[10]{(1+r)^{10}}$

$\sqrt[10]{2} =1+r$

Subtract 1 from both sides

$\sqrt[10]{2}-1=r$

$r=\sqrt[10]{2}-1$

$r=1.0718-1$

$r=0.0718$

We can conclude that the growth rate of our exponential equation is $r=0.0718$ . The closest value from your given choices is C)r=0.69

A cone has a radius of 1.2 inches and a height pf 2.9 inches. What is the volume, to the nearest tenth of a cubic inch,of a cone

notsponge [240]

9514 1404 393

Answer:

4.4 in³

Step-by-step explanation:

The formula for the volume of a cone is ...

V = 1/3πr²h

For the given dimensions, the volume is ...

V = 1/3π(1.2 in)²(2.9 in) = 1.392π in³ ≈ 4.4 in³

shusha [124]

Answer:

Step-by-step explanation:

Tangents drawn to a circle from an external point are equal, thus

IH = IJ = 7

ON = OH = 19 - 7 = 12

MN = ML = 26 - 7 = 19

Summing the 4 sides for perimeter (P)

P = 26 + 19 + 7 + 7 + 12 + 19 = 90

Which statement correctly describes the relationship between the graph of f(x) and the graph of g(x)=f(x)+3 ?

Len [333]

Answer:

The graph of g(x) is the graph of f(x) translated 3 units up.

Step-by-step explanation:

Adding 3 to the function will change its input. It will add 3 units to every output and slide the entire function up three units by translation.

Example: f(x) = x f(x) + 3 = x+3

f(1) = 1 f(1) +3 = 1+3 =4
