The length of the longer diagonal of this parallelogram is 10.8.

What are the definitions and properties of a parallelogram?

A parallelogram is a rectangle with two pairs of parallel sides. The lengths of the opposite sides of the parallelogram are equal, and the angles of the opposite sides are the same. Also, the internal angles on the same side of the transversal are complementary. The sum of all internal angles is 360 degrees.

A parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The lengths of the opposite or opposite sides of the parallelogram are equal, and the angles of the opposite sides of the parallelogram are equal.

Substitute values into point-slope form

[tex]y-y_1=m(x-x_1)\\\\y -10=2(x -3)[/tex]

Lerola and her younger sister Kiara are jogging around a circular track. Lerola jogs far enough from the center of the circle that her laps are half a mile long. Kiara runs around a circle whose circumference is as long as Lerola's. How far from the center of the circle is Kiara running, in feet? Use 3.14 for pi. 3 2There are 5280 feet in a mile.

Answers

Circumference of circular track, C = 0.5 miles = 0.5×5280 feet = 2640 feet.

We know, circumference in circle is given by :

[tex]C = 2\pi r[/tex]

( Here, r is radius i.e distance of centre from track )

Putting values in above equation :

2 × 3.14 × r = 2640

6.28 × r = 2640

r = 420.38 feet

Therefore, distance between centre and track is 420.38 feet .

Hence, this is the required solution.

The slope of the table is 2

How to determine the slope?

From the table, we have the following points:

(x,y) = (0, 4) and (1,7)

The slope is then calculated as:

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

Substitute known values

m = (7 - 4)/(1 - 0)

Evaluate the differences

m = 3/1

Divide

m = 2

Hence, the slope of the table is 2

can somebody simply explain a unlinear functions???

Answers

Answer:

The graph of a linear function is a line. ... Linear functions have a constant slope, so nonlinear functions have a slope that varies between points. Algebraically, linear functions are polynomials with highest exponent equal to 1 or of the form y = c where c is constant. Nonlinear functions are all other functions.

nonlinear functions are functions that are not linear functions. Therefore, they have the opposite properties of a linear function. The graph of a linear function is a line. Thus, the graph of a nonlinear function is not a line.

Solve for X

Answers

Answer: 15/7 2 1/7

Step-by-step explanation: First divide 8x-3=x+12 Then add 3 to both sides.

8x=x+15 Subtract x from both sides. 7x=15 Then divide again so 7/7 and 15/7. If you simplify it become 2 1/7

Answer:

x = 15/7

Step-by-step explanation:

Reduce the fraction with 2

8x - 3 = x + 12

Move variable to the left-hand side and change its sign

8x - x - 3 = 12

Move constant to the right-hand side and change its sign

8x - x = 12 + 3

collect like terms

7x = 12 + 3

Add the numbers

7x = 15

Divide both sides of the equation by 7

Solution: x = 15/7

x = 2 1/7, x = 2.142857

Step 1: m∠m + m∠n + m∠o = 180 degrees (sum of angles of a triangle)
Step 2: m∠p − m∠o = 90 degrees (alternate interior angles)
Step 3: Therefore, m∠m + m∠n + m∠o = m∠o + m∠p
Step 4: So, m∠m + m∠n = m∠p

In which step did the student first make a mistake and how can it be corrected?

Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (corresponding angles)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; it should be m∠o + m∠p = 180 degrees (supplementary angles)

find the distance traveled in 15 seconds by an object traveling at a constant velocity of 20 feet per second

Answers

The distance travel by the object would be 300 feet

The distance covered by the object is 300 feet's.

We have - object traveling at a constant velocity of 20 feet per second.

We have to calculate the distance traveled in 15 seconds by the object.

What is the formula to calculate the distance covered by the object ?

The distance covered by the object can be calculated using the formula -

d = v x t

Where -

v - it is the velocity of object

t - time taken by object

According to question -

v = 20 feet/sec

t = 15 seconds

Hence, the distance covered will be -

d = 20 x 15 = 300 feet's

Hence, the distance covered by the object is 300 feet's.
