Answer:

sum = +13

Step-by-step explanation:

The possible factors of 48 are

{1,2,3,4,6,8,12,16,24,48}

Of these, the pair 3,16 gives a sum of 19 and a product of 48.

We are given that 16 (greater absolute value) is positive, so 3 is negative.

The sum of the two is therefore 16-3 = 13

Answer:

196 tickets

Step-by-step explanation:

The total expenses to put on a 3-day production of a play is $980. Each ticket to go and watch the play is going to be sold for $5. The producer sells x number of tickets, x number of tickets would cost 5x. Therefore to find the number of tickets the producer must sell so as to make a profit the money generated from selling the tickets must be more than the cost of production. Therefore we use the formula:

5x ≥ 980

Dividing through by 5:

x ≥ 980

x ≥ 980/5

x ≥ 196

Therefore the producer must sell at least 196 tickets so as to make a profit

Answer:

itS A

Step-by-step explanation:

Answer:

h(x) = x^3

A function has an inverse that is also a function is it is a one-to-one function, a function is one-to-one if each value in the domain is linked to only one value in the range, and if each value in the range is linked to only one value in the domain.

Then, a function that is monotonous growing is always one to one, and a function is monotonous growing if the derivative is positive for all the values of x

The derivative of x^3 is:

h'(x) = 3*x^2

and as you know, x^2 is always equal or greater than zero, so h(x) = x^3 is monotonous growing, then it has a inverse that is also a function.

Hello

-x+4y=-5

so

[tex]4y = x-5\\<=> y=\dfrac{1}{4}x-\dfrac{5}{4}[/tex]

we say that y varies directly with x if y=kx

in this example we have an additional constant, the graph is not a line through the origin so this is not a direct variation

Answer:

k = -18

Step-by-step explanation:

If x-3 is a factor, what this means is that if we substitute;

x = 3 into the equation, we should get 0

This is from the factor theorem

Thus ;

P(3) = 0 = 2(3)^3 -5(3)^2 + 3(3) + k

0 = 54 - 45 + 9 + k

k + 18 = 0

k = -18

Answer:

Vertex: (4, -2)

Vertex form: [tex]y = 2(x-4)^2 - 2[/tex]

Inverse function: [tex]y = (16 \pm\sqrt{16+8x})/4[/tex]

Step-by-step explanation:

The x-coordinate of the vertex can be calculated using the formula:

[tex]x_{vertex} = -b/2a[/tex]

Where a and b are coefficients of the quadratic equation in the form:

[tex]y = ax^2 + bx + c[/tex]

So, using a = 2 and b = -16, we have:

[tex]x_{vertex} = 16/4 = 4[/tex]

To find the y-coordinate of the vertex, we calculate y using the x-coordinate of the vertex:

[tex]y=2*4^2-16*4+30[/tex]

[tex]y = -2[/tex]

So the vertex is (4, -2)

The vertex form is given by:

[tex]y = a(x-h)^2 + k[/tex]

Where h is the x-coordinate of the vertex and k is the y-coordinate of the vertex. Therefore, we have that:

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

To create an inverse function, we switch x by y and vice-versa:

[tex]x=2y^2-16y+30[/tex]

[tex]2y^2-16y+30 - x = 0[/tex]

Then, using Bhaskara's formula, we have:

[tex]\Delta = b^2 -4ac = (-16)^2 - 4*2*(30-x) = 16 + 8x[/tex]

[tex]y = (-b \pm\sqrt{\Delta})/2a[/tex]

[tex]y = (16 \pm\sqrt{16+8x})/4[/tex]

It's important to say that this inverse function is not really a function, because one value of x gives two values of y.

Answer:

Step-by-step explanation:

[tex]\sqrt{16x^{16}}=\sqrt{16}\cdot\sqrt{x^{16}}=4\cdot x^8[/tex]

Step-by-step explanation:

Two sides of one triangle are congruent to two sides of the other triangle. The included angles of the two triangles are congruent.

The triangles are congruent by SAS.

Answer:

a) [tex]\angle G = 125^\circ[/tex]

b) AG = 15 units

c) Perimeter of polygon SUBAG = 78 units

Step-by-step explanation:

Given:

Polygon ROTFL ~ Polygon SUBAG

Similar polygons mean they have similar angles and the ratio of corresponding sides and ratio of their perimeter are equal.

Part A:

Given that

[tex]m\angle R = 100^\circ\\m\angle O = 120^\circ\\m\angle T = 75^\circ\\M\angle L = 60^\circ[/tex]

[tex]m\angle L+M\angle L = 180^\circ\\\Rightarrow m\angle L=180-60=120^\circ[/tex]

Sum of all interior angles of a pentagon is [tex]540^\circ[/tex]

[tex]m\angle R+m\angle O+m\angle T+m\angle F+m\angle L=540^\circ\\\Rightarrow 100+120+75+m\angle F+120=540^\circ\\\Rightarrow m\angle F=125^\circ\\[/tex]

Due to similarity property of the two pentagons, [tex]\angle F =\angle G = 125^\circ[/tex]

Part B:

Ratio of corresponding sides is equal.

Given the sides SU = 12, RO = 8 and FL = 10 units respectively.

[tex]\dfrac{SU}{RO}=\dfrac{AG}{FL}\\\dfrac{12}{8}=\dfrac{AG}{10}\\\Rightarrow AG = 15\ units[/tex]

Part C:

Ratio of corresponding sides must be equal to ratio of perimeter of the two polygons:

[tex]\dfrac{RO}{SU} = \dfrac{\text{perimeter of ROTFL}}{\text{perimeter of SUBAG}}\\\Rightarrow \dfrac{8}{12} = \dfrac{52}{\text{perimeter of SUBAG}}\\\Rightarrow \text{perimeter of SUBAG} = 52 \times 1.5\\\Rightarrow \text{perimeter of SUBAG} = 78\ units[/tex]

So, the answers are:

a) [tex]\angle G = 125^\circ[/tex]

b) AG = 15 units

c) Perimeter of polygon SUBAG = 78 units

Step-by-step explanation:

y = 9x + 8

y = 7.5x + 16

1.5x = 8

x = 5.3 hours

Answer:

5.3hrs or 5hrs 18mins

Step-by-step explanation:

First, we have to put the information given to us about the money they earn into an expression

Let x represent the number of hours Kini and Duke work and y represent the total amount of money they earn in a week.

y(kini) = 9x + 8

y(duke) = 7.5x + 16

Now we subtract the x values and the constant values

9x - 7.5x = 1.5x

16 - 8 = 8

Make these into an equation

1.5x = 8

Divide both sides by 1.5 so x(the number of hours the both work) can stand alone.

[tex]\frac{1.5x}{1.5} =\frac{8}{1.5}[/tex]

x = 5.3hrs or 5hrs and 18 mins

Answer:

Step-by-step explanation:

We know that both Emily and Fred gave Gary, who had no money, a total of $15. We also know that now they have the same amount of money (they all have $15). We simply have to add the values each person gave to Gary:

Emily: 15 + 9 = 24

Fred: 15 + 6 = 21

Answer:

The history instructor has made a computational error.

Step-by-step explanation:

We have that the data represents the linear correlation coefficient and notes it is 1.15

The linear correlation coefficient value which is 1.15 does tell the instructor that the history instructor has made a computational error due to the linear correlation coefficient value falls in the range -1 to +1.

Therefore, the history instructor has made a computational error.
