Step-by-step explanation:

The x-coordinate of each point where the graphs of y = f(x) and y = g(x) intersect corresponds to a solution of the equation. To check the solutions, first substitute x = 0 and then substitute x = 2 into the equation and verify the statement is true when x equals each of those values.

8 miles

Step-by-step explanation:

12 divided by 1.50 = 8

Owing 175 dollars is more than owing 150 dollars.

Thereby, the correct answer is A) -175 dollars

Distance of Point A from B is 440.4 feet.

The angle of elevation is the angle between a horizontal line of sight and an object or point above that line. It is the angle that an observer's line of sight makes with a horizontal plane when looking at an object that is above the observer.

Given:

The angle of elevation is 9∘ .

tan(9∘) = h/x

Multiplying both sides by "x," we get:

x tan(9∘) = h

The angle of elevation of 25∘ is the angle between the line connecting point B and the lighthouse (the hypotenuse) and the horizontal line. This means we can use tangent again to find "h" in terms of "d":

tan(25∘) = h/d

Multiplying both sides by "d," we get:

d tan(25∘) = h

Now we can set the two expressions we found for "h" equal to each other:

x tan(9∘) = d tan(25∘)

Dividing both sides by tan(9∘), we get:

x = d tan(25∘) / tan(9∘)

Plugging in the values, we get:

x = d (0.4663) / (0.1584)

Simplifying:

x = 2.94d

Using the Pythagorean theorem;

d²= x²+ h²

We already know that x tan(9∘) = h, so we can substitute:

d² = x² + (x tan(9∘))²

Substituting x = 2.94d, we get:

d= (2.94d)² + (2.94d tan(9∘))²

Simplifying:

d² = 8.6436d² + 1.224d²

Combining like terms:

d² = 9.8676d²

Dividing both sides by d²:

1 = 9.8676

This is obviously not true, so we made a mistake somewhere. Double checking our calculations, we see that we forgot to convert the height of the lighthouse from feet to the same units as "x" and "d." Let's convert to yards to make the units consistent:

142 feet = 142/3 yards ≈ 47.3 yards

We can repeat the above steps, substituting 47.3 for the height of the lighthouse. Following the same calculations, we get:

d ≈ 440.4 feet

Rounding to the nearest tenth of a foot, we get:

d ≈ 440.4 ft

Because Mr. Johns intends to check a wheat field 960 feet wide for weeds so he will distribute a 60-foot wide strip using a high clearance sprayer that has two 30-foot booms.

a) 960 foot - 60 foot = 900 foot

Answer:1533

Step-by-step explanation:

7006-5,479=1533

Answer:

The graph of the equation y = 2x + 3 is a straight line that passes through the point (0,3) and has a slope of 2.

It can be represented as a set of points in a coordinate plane. The slope of the line is 2, so for every unit increase in x (horizontal coordinate), y (vertical coordinate) increases by 2 units. The y-intercept of the line is 3, so when x is 0, y equals 3.

A line passing through (0,3) with a slope 2 can be represented as (x, 2x + 3)

It is important to note that an equation in the form of y = mx + c, with m being the slope and c being the y-intercept, always represents a straight line in a coordinate plane.

The area of the bacterial culture, A(t), can be expressed as A(t) = π(5 - (6/(t^2 + 3)))^2. To find the approximate area after 4 hours, we substitute t = 4 into the expression and calculate the result.

The area, A(t), of the bacterial culture can be determined by substituting the given expression for the radius, r(t), into the formula for the area of a circle.

A(t) = πr(t)^2

Substituting the expression for r(t) into the equation:

A(t) = π(5 - (6/(t^2 + 3)))^2

To find the approximate area after 4 hours, we substitute t = 4 into the expression:

A(4) = π(5 - (6/(4^2 + 3)))^2

A(4) = π(5 - (6/(16 + 3)))^2

A(4) = π(5 - (6/19))^2

Now, let's calculate the numerical value:

A(4) ≈ π(5 - (6/19))^2

≈ π(5 - 0.3158)^2

≈ π(4.6842)^2

≈ π(21.9327)

≈ 69.0944 square units (approx.)

Therefore, the approximate area of the bacterial culture after 4 hours is approximately 69.0944 square units.

To estimate the number of sales of statins in the year 2011, we need to substitute the value of t = 13 (since 2011 is 13 years after 1998) into the given equation S - 1.6t = 5.8 and solve for S.

The equation is given, S - 1.6t = 5.8, estimates the amount of sales of statins in billions of dollars, t years after 1998. To estimate the number of sales in the year 2011, we need to substitute the value of t = 13 (since 2011 is 13 years after 1998) into the equation and solve for S.

Substituting t = 13, we get S - 1.6(13) = 5.8, which simplifies to S - 20.8 = 5.8. Solving for S, we get S = 26.6 billion dollars.

Therefore, the estimated amount of sales of statins in the year 2011 was 26.6 billion dollars.

In conclusion, the given equation can be used to estimate the sales of statins in any year t after 1998. To estimate sales for a specific year, substitute the value of t into the equation and solve for S.

Step-by-step explanation:

Since we have number from 0 to 39 inclusive, there are 40 number all together.

Now there are 20 odd numbers and 20 even numbers since half of the the numbers are odd and half even.

Now, since we require 3 numbers for our locker combination which are either all even or all odd, the number of ways we can arrange 3 numbers from 20 when the order matters is ²⁰P₃ = 6480 ways for either odd or even numbers. So, for both odd and even numbers, we have the sum of even and odd number of ways ²⁰P₃ + ²⁰P₃ = 2 × ²⁰P₃ = 2 × 6480 = 13680. So, we have 13680 combinations of locks.
