If the expression 16t² models the distance in feet that an object falls during the first t seconds after being dropped, then the distance of the object during 0.5 second is 4 feet

Given,

The expression model of the distance in feet that an object falls during the first t second after being dropped = [tex]16t^{2}[/tex]

Time = 0.5 second

Then the distance = [tex]16(0.5)^{2}[/tex]

=16×0.25

=4 feet

Hence, if the expression 16t² models the distance in feet that an object falls during the first t seconds after being dropped, then the distance of the object during 0.5 second is 4 feet.

The difference of the polynomials, (p² + p - 8) - (-4p² - p + 3), is: D. 5p² + 2p - 11.

To find the difference of two polynomials, group like terms together after opening up the parentheses, then combine the like terms together.

Given the polynomials:

(p² + p - 8) - (-4p² - p + 3)

Apply the distributive property to eliminate the parentheses

p² + p - 8 -1(-4p²) -1(-p) -1(3)

p² + p - 8 + 4p² + p - 3

Group like terms

p² + 4p² + p + p - 8  - 3

Combine like terms

5p² + 2p - 11

Thus, the difference of the polynomials, (p² + p - 8) - (-4p² - p + 3), is: D. 5p² + 2p - 11.

Yes, the given set of numbers can be the measures of the sides of a triangle. The triangle is obtuse.

By the triangle inequality theorem, the sum of the lengths of any two sides should be greater than the length of the third side.

4 + 12 > 14

12 + 14 > 4

14 + 4 > 12

Hence, these set of numbers can be the measures of the sides of a triangle.

According to the Pythagorean Inequality Theorem, a triangle whose sides measure a, b, and c where c is the largest, the triangle can be characterized as:

acute if [tex]c^{2} < a^{2} + b^{2}[/tex]

obtuse if  [tex]c^{2} > a^{2} + b^{2}[/tex]

right if  [tex]c^{2} = a^{2} + b^{2}[/tex]

∴The longest side is 14.

Hence, a = 4, b = 12 and c = 14;

Consider        [tex]a^{2} + b^{2}[/tex] :

[tex]= 4^{2} + 12^{2}[/tex]

= 160.

Now consider [tex]c^{2}[/tex] :

= [tex]14^{2}[/tex]

= 196.

Thus, [tex]c^{2} > a^{2} + b^{2}[/tex]

Hence, the triangle is obtuse.

The measurement of each angle is : m∠A = 108° , m∠B = 36° , m∠C = 36°.

In mathematics, an isosceles triangle is a triangle in which any of the two sides are equal. Or we can say that if a triangle has at least two sides of equal length then it is known as isosceles triangle. In geometry, isosceles triangle follow the property of congruency of triangles. That means in an isosceles triangle the two angles of equal sides are congruent to each other.

In the given question,

Let m∠B = m∠C = x  , where m denotes measure of angle

therefore, m∠A = 3x

According to Triangle Angle-Sum Theorem,

m∠A + m∠B + m∠C = 180

thus,

3x + x + x = 180

5x = 180

x = 36

Hence,

m∠A = 3x = 180

m∠B = 36°

m∠C = 36°

Therefore, the measure of each angle A , B and C is 180°, 36° and 36° respectively.

The distance traveled in each section will be 150 meters and 350 meters.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

From a simultaneous equation for: A cyclist completes a journey of 500 m in 22 seconds, part of the way at 10m/s and the remainder at 50m/s.

Let x distance be covered with velocity 10 m/s in time t₁ and the remaining distance (500 - x) covered with velocity 50 m/s in time t₂. Then the equation will be

t₁ + t₂ = 22          ....1

Then the time t₁ will be

10 = x / t₁

t₁ = x / 10

Then the time t₂ will be

t₂ = (500 - x) / 50

Put the time in equation 1, then we have

x / 10 + (500 - x) / 50 = 22

5x + 500 - x = 1100

4x = 600

x = 150 meters

And the remaining distance will be

500 - x = 500 - 150

500 - x = 350 meters

The distance traveled in each section will be 150 meters and 350 meters.

The formula for the height of a cylinder is h = V / (π.r²) and the height of a cylinder with a volume of 36 cm³ and a radius of 3 cm is  4/π cm

Given a cylinder with a radius r and height h, then its volume is given by the formula:

      V = π.r².h

Where:

V = volume

r = radius

h = height

To find the formula for the height, divide both sides by π.r²

V : π.r² = π.r².h : π.r²

or,

           h = V / (π.r²)

The given parameters are:

V = 36 cm³

r = 3 cm

Substitute those parameters into the formula:

h = 36 / (π.3²)

h = 36 / (9π)

The equation of the line in point-slope form, which passes through the points located at (1 , 0) and (5 , 5), is y = 5/4(x - 1).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Getting the slope of the two points: (1 , 0) and (5 , 5).

m = (y2 - y1)/(x2 - x1)

m = (5 - 0)/(5 - 1)

m = 5/4

Using the point slope form, plug in the values of the slope and one point to set up the equation.

(y - y1) = m(x - x1)

where m = 5/4 and (x1 , y1) = (1 , 0)

The correct option is A. 1/18. Shannon has a 1/18 chance of being in the second P.E. class along with the first lunch.

Two events are considered independent if the happening of the one doesn't affect the likelihood of the happening of the other.

The mathematical model of event independence A and B is the probability of both A and B occurring becoming equal to the product of a probabilities of A & B.

Now, for the stated question;

Let the probability that the Shannon will get second P.E class is P(A) = 1/6.

Now, Let the probability that the Shannon will get first lunch is P(B) = 1/3.

Ad, both events are independent.

Thus, the intersection will be -

P (A∩B) = P(A).P(B)

P (A∩B) = 1/6×1/3

P (A∩B) = 1/18.

Therefore, the probability that Sharron will be in the second P.E. class and the first lunch is 1/18.
