Answer:
400
Step-by-step explanation:
You want to know the number of foxes predicted after 42 years by y = 50·2^x, where x is measured in 14-year periods.
Periods42 years is 42/14 = 3 14-year periods. Using x=3 in the equation, we predict ...
y = 50·2^3 = 50·8 = 400
foxes.
After 42 years, there will be 400 foxes.
__
Additional comment
It is often convenient to use time measured in 1-year periods. In that case, the equation could be written ...
y = 50·2^(t/14)
Then t/14 is the number of 14-year periods when t is in years.
(7 × 10) + (7 × 10%) + (7 × 10²) = 700 070.07
Write down a possible set of values for x, y and z.
The equation (7 × 10) + (7 × 10%) + (7 × 10²) = 700 070.07 can be rewritten as:
7x + 0.7y + z = 700 070.07
To find a set of values for x, y, and z that satisfies this equation, we can use trial and error. One possible set of values is:
x = 100
y = 10
z = 7000
If we plug these values into the equation, we get:
(7 × 100) + (7 × 0.1) + (7 × 7000) = 700 070.07
Which simplifies to:
700 + 0.7 + 49000 = 700 070.07
This equation is true, so the values x = 100, y = 10, and z = 7000 are a solution to the original equation.

Answer:
[tex]\huge{\boxed{2 \text{ units}}}[/tex]
Step-by-step explanation:
N.B. I attached an image of the number line as presented by the problem.
The absolute value of a number is its distance from zero. A simple way to say that is that the absolute value of a number is the number made positive and is denoted by "||"
i.e.
|-4| = 4
|4| = 4
|-219| = 219
The distance between two points on a number line is the absolute value of their difference. Thus, simply do:
|5 - 3|
|2|
2
OR
|3 - 5|
|-2|
2
Thus, the length of the segment is simply 2.

PART A: Given the rate at which the zookeeper is giving the animals hay and grain, on which day will she have the same amount of grain and hay remaining? Explain how you determined your answer
Given the rate at which the zookeeper is giving the animals hay and grain, on which day will she have the same amount of grain and hay remaining is 6 days.
Every three days, one pound of hay and one pound of feed are used.
10 pounds of grain and 8 pounds of hay are present.
There are 6 pounds of hay and 6 pounds of grain left on the sixth day.
A rate in mathematics is the comparison of two related values expressed in different units.
The numerator of the ratio indicates the rate of change in the other (dependent) variable if the denominator of the ratio is written as a single unit of one of these quantities, and if it is assumed that this quantity may be modified systematically (i.e., is an independent variable).

Given that,
We have to find the distance between the points (3,5) and a line with the equation 5x-3y+10=0.
We know that,
We have a formula that is
Let (x₁, y₁) be the point and ax + by + c = 0 be the line.
Then the distance between a point and a line will be
d=|ax₁+by₁+c|/√(a²+b²)
Here,
(x₁,y₁)=(3,5)
a=5, b=-3 and c=10
So, substituting
d=|5(3)+(-3)(5)+10|/√(5²+(-3)²)
d=|15-15+10|/√25+9

The measure of arc PD is 56.
What is a measure of arc?
The central angle that creates the intercepted arc's central angle, or the arc measure, is expressed in degrees. Arc length can be estimated as a percentage of the circle's circumference by multiplying the circle's diameter by the arc length, divided by 360.
Here, we have
Given: DR = 4x +4
PR = 50°
The sum of the measure of arc PR + DR = 180°
50° + 4x +4 = 180°
x = 4

Multiple choice:
-$4.62
-$1.00
$1.00
$4.62
Answer:
Hope this helps, Good Luck! :)
Step-by-step explanation:
EV = - + prob(win)*win
= -5 + 1/1000 * 375
= -4.62
The requried, the expected value for a person that buys one ticket is approximately -$4.62. The correct answer is option A. -$4.62.
To calculate the expected value, we need to consider the probability of winning the color television and the corresponding value of the prize. We can then subtract the cost of buying the ticket to find the expected value.
Given:
Cost of one ticket = $5
Value of the color television (prize) = $375
Number of tickets sold = 1000
The probability of winning the color television is 1 out of 1000, as only one ticket will be selected out of the total 1000 tickets sold.
Expected Value (EV) = (Probability of winning * Value of prize) - Cost of the ticket
EV = (1/1000 * $375) - $5
EV = $0.375 - $5
EV = -$4.625
