Step-by-step explanation:

the general vertex form is

y = a(x - h)² + k

with (h, k) being the vertex of the curve.

after doing all the multiplications we get

y = a(x² - 2hx + h²) + k = ax² - 2ahx + ah² + k

now we have

y = x² + 24x + 124

and we can compare

ax² = x²

a = 1

-2ahx = -2hx = 24x

-2h = 24

h = 24/-2 = -12

ah² + k = 124

(-12)² + k = 124

144 + k = 124

k = -20

so, the vertex form is

y = (x + 12)² - 20

Based on the above information, it can be inferred that Sarah saves $6,900 per year.

Taking into account that her new employer is going to give her a free health service and that before she paid $575 for the health service monthly, to calculate her savings per year we must multiply the value of the health service by the number of months of one year (12).

Based on the above, it can be inferred that Sarah is saving $6,900 per year on health care.

Step-by-step explanation:

To solve the inequality:

4x + 8 ≥ -4

4x ≥ -12

x ≥ -3

If this is what you did then I'm not sure how you ended up getting x ≤ -3. You're not dividing by a negative number so the sign never switches.

Hope this helps

Step-by-step explanation:

−4≤4x+8

Subtraction property of inequality with the value 8.

-12≤4x

Division property of inequality with the value of 4.
The reason the sign stays as less than or greater to is because the sign only switches when the DIVISOR is negative, not the dividend.

Answer:

It would take 45 men 5 days to make 500 watches.

Explanation.

for 15 men it takes 15 days.

but if you have 45 men. that is 3x the amount of men.

they will be able to make watches 3 times faster.

just believe me its the right answer.

Please Vote Me Brainliest. Thank You.

(Assuming every single man has the same working rate.)

Solution 1 :

If there is 45 men working, there will be 45 : 15 = 3 times as much men.

So, the amount of time taken will be reduced by 3 times.
=> It will take 15 : 3 = 5 days for 45 men to produce 500 watches.

Solution 2 :

15 men produce 500 watches in 15 days -> If there is only 1 man, it will take 15 x 15 = 225 (days).

If there is 45 men, the amount of time will reduce by 45 times.

So, it will take 225 : 45 = 5 days for 45 men to produce 500 watches.

I assume you mean the equation

[tex]i^{2x+3} = i[/tex]

Since i = √(-1), we have i⁴ = 1 and so i⁵ = i. Then 2x + 3 must be some multiple of 5.

Now just check for which of the given choices that this holds:

x = 16   ⇒   2x + 3 = 35   (yes)

x = 11   ⇒   2x + 3 = 25   (yes)

x = 10   ⇒   2x + 3 = 23   (no)

x = 14   ⇒   2x + 3 = 31   (no)

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a trigonometric function:

Answer:

9x^2(5y^2 + 2x).

Step-by-step explanation:

First find the Greatest Common Factor of the 2 terms.

GCF of 18 and 45 = 9

GCF of x^2 and x^3 = x^2.

The complete GCF is therefore 9x^2.

So, dividing each term by the GCF, we obtain:

9x^2(5y^2 + 2x).

Using the concept of the degree of a polynomial, it is found that the correct option is given by:

Degree(R(x)) = Degree(Q(x)) - 1.

It is the highest exponent of it's equation.

When two polynomials are divided by each other, the degree of the remainder can be at most one less than the degree of the dividend, hence the correct option is given by:

Degree(R(x)) = Degree(Q(x)) - 1.

The area of a trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis is 37.5 square units.

A trapezium is a quadrilateral having two opposite sides parallel.

The area of a trapezium is equal to;

[tex]\rm Area =\dfrac{1}{2} \times \text{Distance between the parallel sides} \times \text{Sum of the parallel sides}[/tex]

The trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis.

The vertices are at (0,10), (10,10),(5,5) and (0,5)

You need to find the area of the rectangle (0,10) (10,5) (0,5) and (5,5)

The lengths are 5, 5,5,5.

The area of the legs is = 5 × 5 =25

The area is;

[tex]\rm Area =\dfrac{1}{2} \times \text{Distance between the parallel sides} \times \text{Sum of the parallel sides}\\\\Area =\dfrac{1}{2} \times 5 \times 5\\\\Area =12.5[/tex]

And the right triangle (10,5),(5,5), and (10,10) the right angle is at (10,5)

the two legs are lengths 5 and 5

so together they are 25 +12.5=37.5 square units.

Hence, the area of a trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis is 37.5 square units.
