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

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

Answers

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

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.)​

Answers

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.

Which of these statements is true? Sin 18° = cos 72°, sin 55° = cos 55°, sing 72° = cos 18°c both a and c

Answers

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°

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? *

Answers

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

x is inversely proportional to the square root of y
When x = 12, y = 9
Find the value of x when y= 81

Answers

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.

If the sequence 4, 8, 12, 16 continues, what will be the 7th
term?

Answers

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

A square has an area of 313.29m2.
Work out the perimeter of the square.

Answers

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.
