Hello there! The answer is C.

So the equation is y = 14.08 ⋅ 2.08^x, where x stands for the number of years. You are finding the number of fish after five years, so place five in for x and solve.

y = 14.08 ⋅ 2.08^5 - Start by finding 2.08 to the 5th power. (I rounded off some decimal points since it was too long.)

y = 14.08 x 38.9329 - Next: multiply your two numbers.

y = 548.175232, or C since it is the closest whole number.

Find the slope between (1, 1) and (10,5)

Natali5045456 [20]

Answer:

Slope = 4/9

Step-by-step explanation:

Let's find the slope between your two points.

(1, 1) ; (10 , 5)

(x1, y1) = (1, 1)

(x2, y2) = (10, 5)

Use the slope formula:

m = y2 − y1 / x2 − x1

= 5 − 1 / 10 − 1

= 4 / 9

Answer:

m = 4 / 9

hope this helps! i would really appreciate it if i get brainliest :)

How do you solve this

Wittaler [7]

use sine law. x = 16.3cm

Step-by-step explanation:

Since triangle angles add up to 180 deg

angle F = 180 -87 -40 = 53

side EF/ sin (angle G) = side EG / sin (angle F )

EF / sin(87) = 13 / sin(53)

EF = 13/sin(53) × sin(87)

EF = 16.3cm

A thief steals an ATM card and must randomly guess the correct pin code that consists of four digits (0 through 9) that must be

stiv31 [10]

The lowest value he'd be able to produce is 0000. The highest value he'd be able to produce is 9999. This means that the thief would have to select the correct pin out of 10,000 combinations. So his chances of selecting the correct pin on his first try would be:

1/10,000

{1 out of 10,000}

A concession stand sell hot dogs and hamburgers. At a football game, 84 hot dogs and 36 hamburgers were sold for $276. At anothe

ICE Princess25 [194]

Answer:

The concession stand sold 46 hot dogs and 32 hamburgers.

Step-by-step explanation:

The first thing to do in algebraic problems is assign variables to things we don't know, so let's start there:

We don't know how many hot dogs the concession stand sold, so we will call that number d.

We don't know how many hamburgers the concession stand sold, so we will call that number h.

Now we translate the statements into algebraic equations:

The number of hot dogs and hamburgers that were sold is 78, so d+h=78.

If each hot dog is sold for 1.25, then the total revenue from hot dogs is given by 1.25d. In the same way, the total revenue from hamburgers is 1.50h. The total revenue from both hot dogs and hamburgers should be the sum of these, and since we are told the total revenue is 105.50, we can say 1.25d+1.5h=105.5.

We now have a system of two linear equations:

d+h=78

1.25d+1.5h=105.5

We can solve it using several methods, though I'm going to go with substitution. Use the first equation to solve for d:

d+h=78

→d=78−h

Now plug this in for d in the second equation:

1.25d+1.5h=105.5

→1.25(78−h)+1.5h=105.5

Solving for h, we have:

97.5−1.25h+1.5h=105.5

0.25h=8

h=8.25→h=32

Since h+d=78,

32+d=78→d=46

The concession stand therefore sold 46 hot dogs and 32 hamburgers.

Can anyone solve these? Pre-Calc BC

Answer:

79. [7, 12], [1, 6]

80. The total revenue in the month of May is $11,575

81. The total revenue in the month of November is $4,630

82. Values obtained from the model and actual values are almost the same, so the given model is precise.

Step-by-step explanation:

79.

The domain of a function is the set of x-values that we are allowed to plug into our function.

The graph below represents f(x),

the graph that the domain of the first part of the function is [7,12]. The domain of the second part of the function is [1,6]. The solution is:

$f(x)=\left \{ {{-1.97x+26.3, 7 \leq x \leq 12} \atop {0.505x^{2} -1.47x+6.3, 1 \leq x \leq 6}} \right. \\\\$

80.

1 ≤ 5 ≤ 6, so we'll plug the value 5 in the function f(x) = 0.505x² - 1.47x + 6.3

f(x) = y = (0.505)(5)² - 1.47(5) + 6.3

f(x) = y = (0.505)(25) - 7.35 + 6.3

f(x) = y = 12.625 - 1.05

f(x) = y = 11.575

For x=5 which represents 5th month May, we got y=11.575

Therefore, the total revenue in the month of May is 11.575 thousands dollars, ie 11,575 dollars.

81.

7 ≤ 11 ≤ 12, so we'll plug the value 11 in the function f(x) = -1.97x + 26.3

f(x) = − 1.97(11) + 26.3

= − 21.67 + 26.3

= 4.630.

For x=11 which represents 11th month November, we got y=4.630 Therefore, the total revenue in the month of November is 4.630 thousands dollars, 4,630 dollars.

82.

Values obtained from the model are y=11.575 (x=5) and y=4.630 (x=11). Actual data values are y=11.5 (x=5) and y=4.4 (x=11)

By comparing these values, we can conclude that the model is precise, because these values are almost the same.
