Answer:

It should be C. 620

Step-by-step explanation:

Using proportions, it is found that Azul will need to save $155 per month for the next 4 years, and the correct option is B.

Thus, the amount he has to save for the next 4 years is:

[tex]A = 12300 - 4860 = 7440[/tex]

[tex]\frac{7440}{48} = 155[/tex]

And the correct option is:

B. Azul will need to save $155 per month for the next 4 years.

Answer:

Step-by-step explanation:

The equation of shifted function y = ax² is y = a(x-h)²+k, where h tells us how many units we move left (h<0) or right (h>0) and k tells how many units up (k>0) or down (k<0)

y = x² - 20 = 1(x - 0)² + (-20)   ⇒  k = -20<0

So it's shifted 20 units down.

Step-by-step explanation:

A. (5,-4)

The vertex of the graph of the function is (5,-4).

The answer is option A.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To find the vertex of the function y = x² - 10x + 21,

We can use the formula:

x = -b/2a

where a is the coefficient of the x² term, b is the coefficient of the x term, and x is the x-coordinate of the vertex.

In this case,

a = 1 and b = -10, so:

x = -(-10)/(2 x 1) = 5

To find the y-coordinate of the vertex, we can substitute x = 5 into the function:

y = (5)² - 10(5) + 21 = -4

Therefore,

The vertex of the graph of the function is (5,-4).

The simplified form of 3√(512) using radical is 48√(2).

To simplify √(512), find the prime factorization of 512.

Prime factorization of 512:

512 = [tex]2^9[/tex]

Now, rewrite the square root as follows:

√(512) = √[tex](2^9)[/tex]

Next, use the property of square roots that states √(a * b) = √(a) * √(b):

√[tex](2^9)[/tex] = √([tex]2^8 * 2)[/tex]

         = √[tex](2^8) * \sqrt(2)[/tex]

Since √[tex](2^8)[/tex] is equal to [tex]2^4[/tex] then

√(512) = [tex]2^4[/tex] * √(2)

Finally, simplify √(2) as it is not a perfect square:

√(512) = [tex]2^4[/tex]* √(2)

          = 16 * √(2)

So, the simplified form is 48√(2).

Answer:

It depends on where point D is placed so C > 0

Step-by-step explanation:

As i said above

We want to find the coordinate of C given that it is the midpoint of BD.

We know that B is at 0, so we can assume that each letter represents a position on the number line.

Then we can assume that D is located at a number different than zero, let's assume that D is located at the value d.

Then the segment BD goes from 0 to d, so its length is d.

Then the midpoint is at the middle, at d/2 plus the smallest value, 0:

C = d/2 + 0 = d/2

Answer:

The equation of this parabola in standard form is (y - 2)² = -8(x - 6) ⇒ B

Step-by-step explanation:

Let us revise the standard form of the equation of a parabola

The standard form of the equation is (y - k)² = 4p(x - h), where

∵ The vertex of a parabola is (6, 2)

→ From the fact above

∴ h = 6 and k = 2

∵ The equation of its directrix is x = 8

→ From the fact above

∴ h - p = 8

→ Substitute the value of h to find p

∵ 6 - p = 8

→ Subtract 6 from both sides

∴ - p = 2

→ Multiply both sides by -1

∴ p = -2

→ Substitute the values of h, k, and p in the form above

∴ (y - 2)² = 4(-2)(x - 6)

∴ (y - 2)² = -8(x - 6)

∴ The equation of this parabola in standard form is (y - 2)² = -8(x - 6)

Answer:

A significant correlation means that there is a significant (in a statistical point of view) correlation between two things.

Then a significant correlation means that we have a (measurable) correlation between the variables in our experiment.

Now, the factors are the variables that experimenters control during an experiment in order to determine their effect on the response variable, then having a positive correlation between two factors, means that when we change one, the other is also affected by the change in the first one.

Then the statement is true.

Answer:

Answer: the answer to this is x=0.5

Step-by-step explanation:

In order to solve this you have to combine the multiplied terms into a single fraction so its going to look like this -   34x/5 + 9.3= -9.4+3.4(2-5x)

The reposition your terms and put together your multiplied terms into a fraction,Once you have that done distribute them

Subtract 9.3 on both sides.you may simplify and then multiply all the terms with the same value to get rid of the denominators from the fractions

also add 85x to both sides then finally divide both side by the same term which get you -59.5/119 and then simplify and you get -0.5

so x= -0.5

Answer:

x=-0.5

Step-by-step explanation:

step 1

6.8x+9.3=-9.4+3.4(2-5x)

6.8x+9.3=-9.4+(3.4)(2)+(3.4)(-5x) distribute

6.8x+9.3=-9.4+6.8+-17x

6.8x+9.3=(-17x)+(-9.4+6.8) combine like terms

6.8x+9.3=-17x+-2.6

6.8x+9.3=-17x-2.6

step 2

add 17x to both sides.

6.8x+9.3+17x=-17x2.6+17x

23.8x+9.3=-2.6

step 3

subtract 9.3 from both sides.

23.8x+9.3-9.3=-2.6-9.3

23.8x=-119

step 4

divide both sides by 23.8

23.8x/23.8= -11.9/23.8

The answer is =-0.5
