what is four minus three

Answer:

  125 meters

Step-by-step explanation:

The ball will hit the ground when its height is zero. Use that value for h in the equation, and solve for d.

__

  h(d) = -d²/125 +d . . . . the given equation

  0 = d(-d/125 +1) . . . . . use h=0, and factor out d

This equation is satisfied by values of d that make the factors zero:

  d = 0   ⇒   d = 0

  -d/125 +1 = 0   ⇒   d = 125

The horizontal distance to the landing point is 125 meters.

Answer: 20.4 feet

Step-by-step explanation:

To find how high the ladder reaches on the wall, first find the relationship between the angle and the wall. The wall is opposite to the angle, so it's possible to solve this equation using sin(58). Sine equals opposite over hypotenuse so sin(58) = x/24. Multiply 24 on both sides to get an equation that can be plugged into a calculator of 24sin(58) = x.

24sin(58) = 20.35, which gets rounded up to a final answer of 20.4 feet.

The second term of the given sequence aₙ = -5(n² + 1n) when solved gives us; a₂ = -20

We are given the formula for a sequence as;

aₙ = -5(n² + 1n)

Where n is the position of the term.

Now, for the first term, we will have;

a₁ = -5(1² + 1(1))

a₁ = -10

The second term of the sequence is;

a₂ = -5(2² + 1(2))

a₂ = -20

Using translation concepts, it is found that the parent function graphed in this problem is [tex]y = \sqrt{x}[/tex].

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, we have only one graph, which has the format of the square root of x, hence the function is:

The trigonometric ratios with their values are based on the triangle will be sin D = 4 / 5, sin C = 3 / 5, sin D x cos D = 12 / 25, tan C x tan D = 1, and cos C x tan D = 16 / 15.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The triangle is given below.

Then the trigonometric ratios with their values are based on the triangle shown in the diagram and will be

sin D = 4 / 5

sin C = 3 / 5

sin D x cos D = 4 / 5 x 3 / 5

sin D x cos D = 12 / 25

tan C x tan D = 3 / 4 x 4 / 3

tan C x tan D = 1

cos C x tan D = 4 / 5 x 4 / 3

cos C x tan D = 16 / 15

Step-by-step explanation:

   First, we will find out how many miles she has left.

-> We will subtract miles travled from total trip.

1,579 miles - 220 miles = 1,359 miles

   Now, we will find the answer to your question.

-> If she has three days left in her trip, we will divide the rest of the miles to travel by 3.

1,359 miles / 3 days = 453 miles

The practical domain of function f(x) has all positive integers and all whole numbers that are multiples of 4 that is option A or D is correct

The domain is "set of all possible inputs value for the function".

According to the question,

A package of buttery round crackers contains 4 sleeves of crackers each

package of crackers cost $2.49. A function f(x) written to represent the cost of purchasing x packages of crackers.

In order to find the practical domain for the function f(x) only if analysis the value of domain function 'x' must positive number so contain 'all positive integers' and since a package of buttery round crackers contains 4 sleeves then domain must contain 'all whole numbers that are multiples of 4'.

Hence, the practical domain of function f(x) has all positive integers and all whole numbers that are multiples of 4.

When you perform the vertical line test on the graphs, the first graph is the only one that passes through a X value multiply times.

The time that the projectile will reach a height of 96 ft and return to the ground will be 6 seconds.

It is the study of the motion of a body without considering mass. And the reason behind them is neglected.

The projectile will reach a height of 96 ft and return to the ground when v₀ = 112 feet per second

The time it takes to reach feet and return to the ground will be

T = 2v₀  /  g

Where g = 32.2 feet per square second.

Then we have

T = 2 x 112 / 32.2

T = 5.956

T ≅ 6 seconds

The standard error is an estimate of the standard deviation of the sampling distribution. The value of the standard error of the mean is 387.970.

It is an estimate of the standard deviation of the sampling distribution. It measures the variability of a considered sample statistic.

Suppose that we're given that:

Population standard deviation = σ

Size of the sample we're working on = n

Then, the standard error can be calculated as:

[tex]SE = \dfrac{\sigma}{\sqrt{n}}[/tex]

where SE denotes the standard error.

The standard error of the mean can be written as,

SE = σ/√n

SE = 2,125/√30

SE = 387.970

Hence, the value of the standard error of the mean is 387.970.
