the slope of the points (8,6) and (2,-2)
Answer:
4/3
Step-by-step explanation:
m = slope
m = y2 - y1 / x2 - x1
m = -2 - 6 / 2 - 8
m = -8 / -6
m = -8/-6
Negative + Negative = Positive
m = 8/6
Both numbers have a common factor of 2
m = 8 ÷ 2 / 6 ÷ 2
m = 4/3

A square has an area of 313.29m2.
Work out the perimeter of the square.
The perimeter of the square is 70.8 meters.
To find the perimeter of a square, we need to know either the length of one side or the area of the square. In this case, we are given the area of the square as 313.29 m².
The formula for the area of a square is:
Area = side length²
We can rearrange this formula to solve for the side length:
Side length = √Area
Substituting the given area into the formula, we have:
Side length = √313.29 m²
Calculating the square root of 313.29, we find that the side length of the square is approximately 17.7 meters (rounded to one decimal place).
Since a square has four equal sides, the perimeter is simply four times the side length:
Perimeter = 4 * 17.7 m = 70.8 meters
As a result, the square's circumference is 70.8 metres.

x is inversely proportional to the square root of y
When x = 12, y = 9
Find the value of x when y= 81
Answer: 4
Step-by-step explanation:
The formula for inverse proportion is x = k / y. Since x is inversely proportional to the square root of y. This will be:
x = k / ✓y
When x = 12, y = 9
We have to calculate the constant of proportionality, k which will be:
12 = k / ✓9
12 = k / 3
k = 12 × 3
k = 36
To find the value of x when y = 81 will be:
x = k / ✓y
x = 36 / ✓81
x = 36 / 9
x = 4
Therefore, x = 4 when y = 81.

Which of these statements is true? Sin 18° = cos 72°, sin 55° = cos 55°, sing 72° = cos 18°c both a and c
Answer:
Sin 18° = cos 72° and sin 72° = cos 18°
Step-by-step explanation:
According to trigonometry identity;
sin Ф = cos(90 - Ф)
for Sin 18° = cos 72
Ф = 18°
Substitute into the expression
sin Ф = cos(90 - Ф)
sin 18 = cos(90 - 18)
Sin 18 = cos 72
Hence the statement id true
For sin 72° = cos 18
Ф = 72°
Substitute into the expression
sin Ф = cos(90 - Ф)
sin 72 = cos(90 - 72)
Sin 72 = cos 18
Hence this statement too is correct
The two correct statements are Sin 18° = cos 72° and sin 72° = cos 18°

Paul wants to visit his aunt who lives 300 miles away from his house. He drives his car at about 50 miles an hour. If X represents the time spent driving and why represents the distance from his aunts house which scatterplot could represent the situation
Answer:
It would take 6 hours.
An equation for that could be: 50x = 300 (X is how long it would take)
So 50 mph• X (time spent) = 300 miles
You didn't give me any scatterplots to look at so I can't help you with that sorry
Monique wants to bake a cake. She needs 2 1/8 cups of sugar, and 1 5/24 cups of flour. How many cups of ingredients will she use in all? *
Answer:
3 1/3 cups total
Step-by-step explanation:
Add together 2 1/8 cups and 1 5/24 cups. The LCD here is 24, and so we rewrite 2 1/8 cups as 2 3/24 cups.
Adding 2 3/24 cups and 1 5/24 cups, we get 3 8/24 cups,
which simplifies to 3 1/3 cups total

If the sequence 4, 8, 12, 16 continues, what will be the 7th
term?
Answer:
28
Step-by-step explanation:
In order to find the seventh term in this arithmetic function, you need to find its function; in order to do this, you must first identify the common difference by finding the difference between two consecutive terms:
16 - 12 = 4; the common difference is 4
Now, you need to find the 0th term, which is the 1st term minus the common difference:
4 - 4 = 0
At this point, you can write out the function (where f(n) = [0th term] + [common difference]n:
f(n) = 4n
Finally, you can plug 7 into this function:
f(n) = 4(7)
f(n) = 28, so the 7th term is 28

One way to solve the quadratic equation x2 = 9 is to subtract 9 from both sides to get one side equal to 0: x2 – 9 = 0. The expression on the left can be factored:
(x + 3)(x – 3) = 0. Using the zero factor property, you know this means x + 3 = 0 or x – 3 = 0, so x = −3 or 3

22 The distance around a meteor crater is 9,031 ft. Find the diameter of the crater. Use 22/7
(Type an integer or decimal rounded to the nearest tenth as needed.)
Answer:
d = 2873.5 feet
Step-by-step explanation:
Given that,
The distance around a meteor crater is 9,031 ft.
We need to find the diameter of the crater. The circumference of a circle is given by :
[tex]C=2\pi r[/tex]
Where
r is the radius of the circle
So,
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{9031}{2\times \dfrac{22}{7}}\\\\r=1436.75\ ft[/tex]
Since,
Diameter, d = 2r
[tex]d=2\times 1436.75\\\\d=2873.5\ ft[/tex]
So, the diameter of the crater is equal to 2873.5 feet.
