Answer:

It is the number of foxes in time t=0.

Step-by-step explanation:

If you evaluate f in x=0, you obtain that f(0) = 185*1.2⁰ = 185*1 = 185. This means that after 0 years, the number of foxes on the reservation is 185. In other words, the reservation starts with 185 years and then it grows. 185 here represents, as a result, the value of f, in other words the number of foxes, at time t=0.

Answer:

Step-by-step explanation:

sin(x)=cos(x) × tan(x)

=(-2√23)×(√24)

=(-2√23)×(2√6)

=(-4√138)

=(-4(2√(3×23)))

=(-8√69)

Your mother gave you $13.32 with which to buy a present. This covered 3/5 of the cost. How much did the present cost

Gala2k [10]

Answer:

$22.20

Step-by-step explanation:

We are told that $13.32 only covered 3/5 of the cost. Does this mean it covered the whole cost? No. The 5 in the denominator represents the whole cost, and the 3 represents the fraction of the cost. In this case, 13.32 represents the 3, as it did not cover the whole cost.

Let's set up our equation by making 13.32 into a fraction.

13.32/x

We will represent the present's actual cost with the letter x.

13.32/x = 3/5

We want to make sure the 13.32 is in the numerator, equal to the 3 in the numerator in the 3/5 number, because we know that $13.32 only covered for a fraction of the present's cost, not the whole cost.

We solve this by doing cross multiplication. Multiply the 13.32 by the 5.

13.32 x 5 = 66.6

Next we divide 66.6 by 3 to get 22.2

66.6/3 = 22.2

This gives us our final answer of $22.20. This means that the cost of the original present was $22.20

REWARDING BRAINLY FOR CORRECT ANSWER

Answer:

Mean: 58

Median: 58

Step-by-step explanation:

The mean is a type of average. It is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the number of values on the list. To find the mean, add up all the values in the set. Then divide the sum by how many values there are.
The median is the middle number; found by ordering all data points and picking out the one in the middle

FINDING THE MEAN:

57 + 54 + 59 + 57 + 61 + 58 + 60 = 406

406 ÷ 7 = 58

FINDING THE MEAN:

Arrange the numbers from smallest to greatest:

54, 57, 57, 58, 59, 60, 61

Find the median number:

54, 57, 57, 58, 59, 60, 61

The median is: 58

Question 6 of 10

Andreas93 [3]

Answer:

C. 31.64

Step-by-step explanation:

23 = sin(36) × Hypotenuse

Hypotenuse is the baseline between the angles 36° and 54°.

Hypotenuse = 23/sin(36)

x = cos(36) × Hypotenuse

x = cos(36) × 23/sin(36) = cos(36)/sin(36) × 23 =

= 1/tan(36) × 23 = 23/tan(36) = 31.63686382... ≈

≈ 31.64
