The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp. Jackie wants to manipulate the
Sauron [17]

The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp.

calculates three times a year, not just once a year.

f(x)= 4(4)^x

3 times a year

so x becomes 3x

f(x)= 4(1+r)^{3x}

4(4)^x=4(1+r)^{3x}

Take log on both sides

log(4)^x=log(1+r)^{3x}

log(4)^x=log(1+r)^{3x}

Use log property and move exponent before log

xlog(4)=3xlog(1+r)}

Divide both sides by x

log 4 = 3 log(1+r)

Solve for '1+r'

log 4 = log(1+r)^3

Remove log from both sides

4 = (1+r)^3

take cube root on both sides

1.584740= 1+r

1+r = 1.59

f(x)= 4(1+r)^{3x}

so equation becomes

f(x)= 4(1.59)^{3x}

1+r = 1.59

subtract 1 from both sides

So r= 59 = 59%

So growth factor is 59%

Answer is option C

​ Quadrilateral ABCD ​ is inscribed in this circle. What is the measure of angle B? Enter your answer in the box. m∠B= ° A quadr
Over [174]

Answer:

m∠B = 157°

Step-by-step explanation:

Cyclic quadrilateral is the quadrilateral whose vertices lie on the edge of the circle

In the cyclic quadrilateral each two opposite angles are supplementary (the sum of their measures is 180°)

∵ Quadrilateral ABCD is inscribed in a circle

- That means its four vertices lie on the edge of the circle

∴ ABCD is a cyclic quadrilateral

<em>Each two opposite angles in the cyclic quadrilateral are supplementary (The sum of their measures is 180°)</em>

∵ ∠B and ∠D are opposite angles in the quadrilateral ABCD

∴ m∠B + m∠D = 180° ⇒ opposite ∠s in a cyclic quadrilateral

∵ m∠B = (6x + 19)°

∵ m∠D = x°

- Substitute them in the rule above

∴ (6x + 19) + x = 180

- Add the like terms in the left hand side

∴ (6x + x) + 19 = 180

∴ 7x + 19 = 180

- Subtract 19 from both sides

∴ 7x = 161

- Divide both sides by 7

∴ x = 23

<em>Substitute the value of x in the expression of the measure of ∠B to find its measure</em>

∵ m∠B = 6(23) + 19

∴ m∠B = 138 + 19

∴ m∠B = 157°

If a transformation is an isometry, how would you describe the relationship between the preimage and the image ?
aleksklad [387]
<span>The inverse image or preimage of a particular subset S of the codomain of a function is the set of all elements of the domain that map to the members of S. Image and inverse image may also be defined for general binary relations, not just functions.</span>
