Answer:

The GCF of 24 and 36 is 12

Step-by-step explanation:

Answer:

f(x) = 2(x - 2)² - 1

Step-by-step explanation:

Given the vertex, (2, -1) and the point, (0, 7), we can plug these values into the vertex form of the quadratic function:

f(x) = a(x - h)² + h

where:

vertex = (h, k)

a = determines whether the graph opens up or down, and the wideness or narrowness of the parabola.

h = determines how far left or right the parent function is translated.

k = determines how far up or down the parent function is translated.

We could substitute the given values into the vertex form, and solve for the value of "a":

f(x) = a(x - h)² + h

7 = a(0 - 2)² - 1

7 = a(-2)² - 1

7 = a(4) - 1

Add 1 to both sides:

7 + 1 = a(4) - 1 + 1

8 = 4a

Divide both sides by 4 to solve for a:

8/4 = 4a/4

2 = a

Since a = 2, and the vertex = (2, -1) then we could plug this value into the given function:

f(x) = 2(x - 2)² -1

Answer:

the nth term of a sequence is usually denoted by the symbole an . a1 =2 the second term is a2=6 and so....

A term is multiplied by 3 to get the next term . if you know the formula for the nth term of a sequence of n , then you can find any term .

formula : an =a1 + ( n - 1 ) d

the truth value is that 10 is higher than 7 or 5 (not sure if this is what you needed)

Answer:

yes, it is a right triangle

Step-by-step explanation:

it follows the pythagorean theorem

if you were to plug in the numbers, it would work

a^2 + b^2 = c^2

6^2 + 8^2 = 10^2

36 + 64 = 100

Based on the information given, the required equation of parabola will be y= -3x² - 14x + 12.

The parabola passes through the points (-1, 23), (1, -5), (3, -57). Let the equation of the parabola be y = ax² + bx + c.

For point (-1, 23), this will be:

23 = a(-1)² + b(-1) + c

23 = a - b + c ..... equation i

For point (1, -5), this will be:

-5 = a(1)² + b(1) + c

-5 = a + b + c .... equation ii

For point (3, -57), this will be:

-57 = a(3)² + b(3) + c

-57 = 9a + 3b + c .... equation iii

From equation i, 23 = a - b + c

Therefore, c = 23 - a + b .... equation iv

Substitute c into equation ii

-5 = a + b + 23 - a + b

-5 = 2b + 23

2b = -23 - 5.

2b = -28

b = -28/2 = -14

Substitute c into equation iii

-57 = 9a + 3b + 23 - a + b

-80 = 8a + 4b.

-80 = 8a + 4(-14)

-80 = 8a - 56

8a = -80 + 56

8a = -24

a = -24/8 = -3

Therefore, the value of c will be:

c = 23 - a + b

c = 23 -(-3) + (-14)

c = 23 + 3 - 14

c = 12

In conclusion, the required equation of parabola will be y = -3x² - 14x + 12.

Solving the quadratic equation, it is found that the duck was underwater for two seconds.

The path of the duck after x seconds is modeled by:

[tex]y = 2x^2 - 4x[/tex]

It is a concave up parabola, thus, the negative values of y, when he is underwater, are between the roots.

To find the roots:

[tex]y = 0[/tex]

[tex]2x^2 - 4x = 0[/tex]

[tex]2x(x - 2) = 0[/tex]

[tex]2x = 0 \rightarrow x = 0[/tex]

[tex]x - 2 = 0 \rightarrow x = 2[/tex]

2 - 0 = 2, thus, the duck was underwater for two seconds.

Answer:

30

Step-by-step explanation:

1. The exterior angle theorem states that the two opposing (in terms of the exterior angle) interior angles of a triangle are congruent to the exterior angle. This means that m∠1 (x) + 90 = 120. Now, we just have to solve for x.

2. (Solving)

Step 1: Subtract 90 from both sides.

Step 2: Check if solution is correct.

Therefore, m∠1 = 30 degrees.

Answer:

∠ 1 = 30°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

120° is the exterior angle of the left triangle , then

∠ 1 + 90° = 120° ( subtract 90° from both sides )

∠ 1 = 30°

Step-by-step explanation:

Answer:

Y = 58

X = 66

Step-by-step explanation:

So the markers mean that those sides of the triangle are congruent. Because of this, we know that the angles opposite from those sides are equal as well.

In the big triangle, Y will be equal to the empty angle. You can then use:

180 = 64 + 2*Y

Then, solving for Y, you get:

Y = (180-64)/2

Y = 58

You can use the same idea for the smaller triangle. The empty angle will be the same as the angle marked as 57.

180 = 57*2 + X

Then, solving for X, you get:

X = 180 - 57*2

X = 66
