A population of beetles are growing according to a linear growth model. The initial population (week 0) is p0=6 and the populati

wel

Answer:

P(n)= p0 + 11(n)

Where p0= population of week 0

P(n) = population of n weeks

n= number of weeks

Step-by-step explanation:

Population of beetles in Week 0= 6

Population of beetles in Week 7= 83

From week 0 to week 7 there are 8 weeks.

But subtracting population of week 0 from population of week 7 gives

= 83-6

= 77

After the subtraction, we have 7 weeks remaining.

Dividing the remaining population by the number of weeks remaining

=77/7

= 11

For n number of weeks, population p of beetles

P(n)= p0 + 11(n)

Where p0= population of week 0

P(n) = population of n weeks

n= number of weeks

Find the equation of a line perpendicular to x=6+6y that passes through the point (-8,6)

alexgriva [62]

Answer:

y = -6x - 42

Step-by-step explanation:

First solve for y in x = 6 + 6y.

6y + 6 = x

6y = x - 6

6/6y = x/6 - 6/6

y = 1/6x - 1 the slope is 1/6.

Perpendicular lines slopes are negative reciprocals of each other.

So the new equation will have the slope of -6 ( the negative reciprocal of 1/6)

Next solve for "b" by using y = mx + b and the new slope of -6 and the point (-8,6)

y = mx + b

6 = -6(-8) + b

6 = 48 + b

-42 = b

The equation of the line is y = -6x - 42

Which of the following terms best describes the set of all points in a plane for which the difference between the distances of a

Gnoma [55]

Answer:

HYPERBOLA

Step-by-step explanation:

We have the statement,

'The set of all points in a plane for which the difference between the distances of a given point to two fixed foci equals a certain constant'.

We know that,

Hyperbola is the set of points such that for point P anywhere on the curve, the absolute distance to the two fixed points is a constant.

i.e. From the figure, we see that, the difference of the distance of P from $F_{1}$ and $F_{2}$ is equal to constant 2a.

Thus, the term representing the given statement is HYPERBOLA.

Samantha has 54 beads. Amanda has twice as many beads as Samantha. They are making bracelets it takes 8 beads to make a bracelet

wlad13 [49]

Answer:

On combining the beads they can make 20 bracelets.

Step-by-step explanation:

The number of beads Samantha has = 54 beads

Number of beads Amanda has = 2 x( Number of beads Samantha has)

= 2 x 54 = 108 beads

The total number of beads Amanda and Samantha has

= 54 beads + 108 beads

= 162 beads

Number of beads required to make 1 bracelet = 8 beads

Now, $\textrm{The number of bracelets made} = \frac{\textrm{Total number of beads they both have}}{\textrm{Beads required to make 1 bracelet}}$

= $\frac{162}{8} = 20.25$ ≈ 20

or, the total number of bracelets they can make is 20.

Hence, on combining the beads they can make 20 bracelets .
