Answer:

The function that describes the height of the ball in time is  \(h(t) = 32\cdot t -16.087\cdot t^{2}\).

Step-by-step explanation:

Let suppose that ball experiments a free fall motion, which means that the ball is accelerated because of gravity and gravitational acceleration can be considered constant since height reached by the object is too small in comparison with the radius of the Earth. Therefore, we can assume that ball is accelerated uniformly.

Hence, the kinematic formula for the height of the ball (\(h(t)\)), in feet, is described below:

\(h(t) = s + v\cdot t + \frac{1}{2}\cdot g \cdot t^{2}\) (1)

Where:

\(s\) - Initial height with respect to the ground, in feet.

\(v\) - Initial velocity, in feet per second.

\(t\) - Time, in seconds.

\(g\) - Gravitational acceleration, in feet per square second.

If we know that \(s = 0\,ft\), \(v = 32\,\frac{ft}{s^{2}}\) and \(g = -32.174\,\frac{ft}{s^{2}}\), then the function that describes the height of the ball in time is:

\(h(t) = 32\cdot t -16.087\cdot t^{2}\) (2)

Answer:

infinite number of solutions

Step-by-step explanation:

2x + y = 1 ( subtract 2x from both sides )

y = 1 - 2x → (1)

4x + 2y = 2 → (2)

substitute y = 1 - 2x into (2)

4x + 2(1 - 2x) = 2 ← distribute parenthesis and simplify left side

4x + 2 - 4x = 2

2 = 2 ← true statement

This indicates the system has an infinite number of solutions

Answer:

infinitely many.

Step-by-step explanation:

Given the equation 2x+y=1 and 4x+2y=2, if we divide the second equation by 2, we are left with 2x+y=1 which is the same equation as the first and this means that the line overlap, and that there are infinite places where they intercept.

Answer:

The prices are equal when it's 12 pages. For 12 pages, she'd be charged $57

Step-by-step explanation:

x = PER page

y = total

Online scrapbooking equation:

y = 45 + x

Family friend equation:

y = 9 + 4x

Where prices (y) would be equal:

y = 45 + x     (Multiply this by -4)

y = 9 + 4x

y = 9 + 4x

-4y = -180 - 4x

-3y = -171

y = 57

y = 45 + x

-y = -9 - 4x

0 = 36 - 3x

3x = 36

Answer:

Step-by-step explanation:

The linear function that models the taxi fare F as a function of the number of miles driven, m can be written as:

F(m) = 2.30 + 0.40(5m - 0.25)

where 5m - 0.25 represents the total distance traveled in fifth of a mile.

To break this down, we start with the base fare of $2.30 for the first quarter of a mile, which is 1.25 fifth of a mile. Then we add the additional distance traveled beyond the first quarter of a mile, which is given by 5m - 0.25. We multiply this by the per-fifth-of-a-mile charge of $0.40.

For example, if a customer travels 2 miles, then the total distance traveled in fifth of a mile would be 10. So, the fare would be:

F(2) = 2.30 + 0.40(5(2) - 0.25) = 2.30 + 3.95 = $6.25

This means that the taxi fare would be $6.25 for a 2-mile ride with the Topology taxi company.

Answer:

The function that describes the height, h in feet, of the rocket, t seconds into launch is h = -16·t² + 138·t

Step-by-step explanation:

The given parameters are;

The initial velocity of the rocket, v = 138 feet per second

The vertical motion formula = h(t) = 0.5·a·t² + v·t + s

The gravitational constant, a = -32 ft./s²

s = The initial height of the rocket

Therefore, he have;

The height of the rocket, t seconds seconds into launch is given as follows;

Height = h = h(t) - s = 0.5·a·t² + v·t

Substituting the known values gives;

h(t) - s = 0.5 × (-32) × t² + 138 × t = -16·t² + 138·t

h = -16·t² + 138·t

The function that describes the height, h in feet, of the rocket, t seconds into launch is h = -16·t² + 138·t.

The second wedge has a greater volume and it is greater by 4.125 in³.

Since the each cheese wedge has a triangular base, its volume V = 1/2bhw where

Given that for the first wedge, b = 2.5 in, h = 4.5 in and w = 3 in, its volume V' = 1/2bhw

= 1/2 × 2.5 in × 4.5 in × 3 in

= 33.75 in³/2

= 16.875 in³

Given that for the second wedge, b = 3 in, h = 4 in and w = 3.5 in, its volume V" = 1/2bhw

= 1/2 × 3 in × 4 in × 3.5 in

= 42 in³/2

= 21 in³

Since V" = 21 in³ > V' = 16.875 in³, the second wedge has a greater volume.

The amount its is greater than the first volume is the difference in their volumes. V" - V' = 21 in³ - 16.875 in³

= 4.125 in³

The second wedge has a greater volume and it is greater by 4.125 in³.

x = 5

Step-by-step explanation:

The given equation is :

2(1+7x)=72

Use the distributive property to the LHS.

2(1)+2(7x) = 72

2+14x = 72

Subtract 2 from both sides.

2+14x-2 = 72-2

14x = 70

x = 70/14

x = 5

Answer:

Step-by-step explanation:a) To find the price of the car before VAT, we need to first calculate the percentage of VAT included in the price:

VAT% = (VAT / Total Price) x 100

where VAT% is the percentage of VAT, VAT is the value of VAT, and Total Price is the price of the car including VAT.

From the given information, we have:

Total Price = Birr 5,000,000

VAT% = 15% (assuming a VAT rate of 15% in Ethiopia)

Therefore, we can solve for the value of the car before VAT as follows:

Total Price = Car Price + VAT

Birr 5,000,000 = Car Price + 0.15Car Price

Birr 5,000,000 = 1.15Car Price

Car Price = Birr 4,347,826.09

So the price of the car before VAT is Birr 4,347,826.09.

b) To find the value of VAT, we can use the same formula as above and solve for VAT:

Total Price = Car Price + VAT

Birr 5,000,000 = Birr 4,347,826.09 + VAT

VAT = Birr 652,173.91

Therefore, the value of VAT is Birr 652,173.91.

To gather evidence supporting or refuting the scientist's claim about the fabric's water repellency, an experiment can be conducted by comparing the water repellency of the two fabrics using a standardized testing method, such as the water droplet test.

The experiment can be designed as follows: Select two fabrics, one being the fabric the scientist claims to be better at repelling water and the other being a different fabric for comparison. Cut identical-sized samples from each fabric and ensure they are in the same condition, such as cleanliness and moisture content.

To test the water repellency, a standardized method like the water droplet test can be employed. This involves placing a droplet of water on each fabric sample and observing how the water interacts with the surface. Factors to consider include the rate of absorption, spreading, or beading of the water droplet. Repeat the test multiple times to ensure consistency.

Measurements and observations should be recorded for both fabrics, noting any differences in water repellency. Statistical analysis can be performed to evaluate the significance of the observed variations.

If the fabric claimed to repel water shows consistently higher rates of beading or slower absorption compared to the other fabric, it would provide evidence supporting the scientist's claim. Conversely, if the two fabrics exhibit similar water repellency characteristics, it would challenge the claim.

By conducting this experiment with proper controls and measurements, evidence can be generated to either support or refute the scientist's claim about the fabric's water repellency.

Answer: A reduced row echelon form (RREF) is a way of transforming a matrix into a simplified form that makes it easier to perform operations such as solving systems of linear equations. A matrix is in reduced row echelon form when it satisfies the following properties:

The first non-zero element in each row, called a pivot, is 1.

Each pivot is the only non-zero element in its column.

The rows above a pivot are zero except for the pivot.

The rows below a pivot are zero.

The columns to the right of a pivot contain only zeros.

An RREF matrix can be used to identify the solutions to a system of linear equations, or to determine if the system has no solutions or infinitely many solutions.
