Point A is located at (-4,\ 9)(−4, 9) on the coordinate plane. Point B is located at (-4,\ -7)(−4, −7). What is the distance between Point A and Point B?
Answer:
AB = 16 units
Step-by-step explanation:
Given the coordinate (-4, 9) and (-4, -7)
Using the formula for calculating the distance between two points
AB = √(x2-x1)²+(y2-y1)²
AB =√(-7-9)²+(-4+4)²
AB = √(-16)²+0²
AB = √16²
AB = 16 units
Hence the distance between Point A and Point B is 16 units

Answer:
21
Step-by-step explanation:
We are to divide the expression
15÷5/7
We can change the sign to a product sign and multiply 15 by reciprocal of 5/7
Reciprocal of 5/7 = 7/5
Multiply with 15
= 15 × 7/5
= 15/5 × 7
= 3 × 7
= 21
Hence the resulting value of the expression is 21

ABCD is a rectangle that represents a park. The lines show all the paths in the park. The circular path is in the center of the rectangle and has a diameter of 15
Complete Question:
ABCD Is a rectangle that represents a park.
The lines show all the paths in the park.
The circular path is in the centre of the rectangle and has a diameter of 15m.
Calculate the shortest distance from A to C across the park,using only the lines shown.
*See attachment for the diagram showing the paths in the park.
Answer:
Shortest distance from A to C through the paths only = 102.9 m
Step-by-step explanation:
Length of park = 80 m
Width of park = 50 m
Diameter of the circular path in the center of the park = 15 m
Therefore:
Shortest distance between from A to C across the park if we're to follow only the lines showing the oaths would be = (length of diagonal AC - diameter of the circular path) + (½ of the circumference of the circular path)
✔️Use pythagorean theorem to find AC:
AC = √(80² + 50²) = √8,900
AC = 94.3398113 ≈ 94.34 m (nearest hundredth)
✔️Diameter of circular path = 15 m
✔️½ of the circumference of the circular path = ½(πd)
d = 15 m
½ of the circumference = ½(π*15) = 23.5619449 ≈ 23.56 m (nearest hundredth)
✔️Shortest distance = (94.34 - 15) + 23.56 = 79.34 + 23.56 = 102.9 m

Given the following rectangle and circle, at what approximate value of x are the two areas equal? Show work and explain all steps.
Answer:
x ≈ 1.28
Step-by-step explanation:
I just took the exam:
Area of rectangle =(3x-1)(x+6), Area of circle = PI(x+1)^2. If you graph these and find where they intersect, you will get x ≈ 1.28.
I hope this helped! :)
The value of x for the two areas to be equal is 167.
AreaArea is the amount of space occupied by a two dimensional object.
The area of the rectangle = length * width = (3x - 1)(x + 2) = 3x² + 5x - 2
Area of circle = π * radius² = π(x - 3)² = πx² - 6πx + 9π
To find x:
πx² - 6πx + 9π = 3x² + 5x - 2
x = 167
The value of x for the two areas to be equal is 167.

In the 1951 science fiction movie classic The Thing from Another World, a group of scientists and soldiers discover a recently crashed alien spaceship buried under a few feet of ice near the North Pole. The party spreads out to determine the size and shape of the alien craft under the blurry ice with the following dialogue: "It's perfectly round...yep, we finally found one...a flying saucer." Assuming that each of the 10 person party is exactly 68 inches (5'8") tall, what would be the diameter of the saucer be in feet rounded to the nearest foot?
Please note that there is insufficient information required to complete this task. The calculation of the diameter of the saucer would have been possible if we were given the width of the 10-person party not their height.
What is the formula for calculating diameter?The formula for calculating the diameter of a circular object in relation to circumference is given as the Circumference of an object divided by Pi (π). That is
If the width of the men were given, and they had stood around the saucer as close to each other as they could, then the circumference of the saucer would have been estimated as:
10 * (width of the men). = 10X
Diameter becomes = 10X/π
Remember, the answer must be in feet.

To multiply out brackets, you multiply the values within the bracket by the one outside one at a time.
For example, for the first one, you would do 2*a, which is 2a, then 2*3, which is 6. Since the 3 was positive, the answer would be 2a+6.
