Answers
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
4n − 2n + 4 = −1 + 17
Step 02:

5. Logan is cooking carrots as part of his dinner. He is in a rush so he wants them to cook as fast as possible. He decides to cut them into small pieces so they cook faster. Will this work? Use the dimensions of two pieces of carrot to justify your answer.
Answers
Let's imagine a piece of carrot that has a shape of a cylinder, and the total surface area of the carrot is S.
If we cut the carrot in half, with a cut parallel to the cylinder base, we will have two smaller cylinders, but the total surface area will increase, since the "internal" part of the bigger cylinder will now be an external area for the new 2 pieces:
In the drawing, the green circles in the right image will add to the total surface area.
If only the base of the cylinder is touching the pan, the surface area will double (from pi*r² to 2*pi*r²), since we will have two pieces of carrot instead of one, with the same base area.
If a bigger surface area is in contact with the pan, the carrots will cook faster. Therefore the answer is YES.

For her cell phone plan heather pays 30 dollars per month plus 0.05 per text. She wants to keep her cell phone bill under 60 dollars per month. Which inequality represents the number of texts t heather can send each month while staying within her budget?
Answers
The inequality represents the number of texts t heather can send each month while staying within her budget is t<600.
Given, heather pays 30 dollars per month plus 0.05 per text.
She wants to keep her cell phone bill under 60 dollars per month.
hence texts she can send = 0.5 × 600
= $30
hence for $30 heather can text upto 600 texts.
so, cell phone plans + text
= $30 + $ 30
= $60
so, the inequality represents the number of texts t heather can send each month while staying within her budget is t<600
Hence the inequality is t<600

Nick used a rope to make a rectangle and a circle below. If 10 cm rope was left, what was the original length of the rope? cm 10 cm 7 cm
Answers
To find the original length of the rope, we must find the length of rope used in the rectangle and in the circle, and add it to the length of rope that was leftover.
The length of rope used in the rectangle would be the perimeter of the rectangle, the perimeter of the rectangle is the sum of all his sides.
Perimeter of a rectangle = side + side + side + side
[tex]\text{Perimeter rectangle= 10+7+10+7=34 cm}[/tex]The question gives us the perimeter of the circle, 20 cm this measure was the length of rope used in the circle.
[tex]\text{Perimeter circle= 20 cm}[/tex]Now the total length of the rope was: The sum of the perimeters of both rectangle and circle and the length of rope that was left.
Total length rope = 34 + 20 + 10 = 64 cm

Jaden and Lola are hosting events that are catered by the same company. Jaden plans to have 82 adults and 96 children attend, so the total projected cost of his meals is $5,664. Lola has 65 adults and 49 children on his guest list, so she will pay the caterer $4,002. How much does the caterer charge for each meal?
Answers
Let's use the variable x to represent the cost of one adult meal, and y to represent the cost of one child meal.
If the cost of 82 adult meals and 96 children meals is $5,664, we can write the following equation:
[tex]82x+96y=5664[/tex]If the cost of 65 adult meals and 49 children meals is $4,002, we can write the equation:
[tex]65x+49y=4002[/tex]To solve this system, let's solve the second equation for y and then use its value in the first equation:
[tex]\begin{gathered} 65x+49y=4002 \\ 49y=4002-65x \\ y=\frac{4002-65x}{49} \\ \\ 82x+96y=5664 \\ 82x+96(\frac{4002-65x}{49})=5664 \\ 82x+7840.653-127.347x=5664 \\ -45.347x=-2176.653 \\ x=48 \\ \\ y=\frac{4002-65\cdot48}{49} \\ y=18 \end{gathered}[/tex]Therefore every adult meal costs $48 and every child's meal costs $18.

Given the following angles of a regular polygon, 120°, (4*x+-3)°, (x+14)°, 45°, 135°, (x-31)°, and (x*6+20)°, what is the value of x?
Answers
Since the polygon has seven angles we deduce it is a heptagon. In that case the sum of the interior angles must be equal to 900°. We can formulate the following equation accordingly.
120°+(4*x-3)°+ (x+14)°+ 45°+ 135°+ (x-31)°+ (x*6+20)° = 900°
120°- 3° +14° + 45° + 135° - 31° + 20 + 4x + x + x + 6x = 900° (Organizing)
300 ° + 12x = 900° (Operating like terms)
12x= 900° - 300° (Transposing 300° to the other side of the equation)
12x= 600° (Subtracting 300° from 900°)
12/12x= 600° / 12 (Dividing by 12 on both sides of the equation)
x= 50°
Answer is: x= 50°

Complex numbers can be written in two forms:

In this case we are given these last two quantities and we have to find a and b. One way to do this is recalling an important property of the exponential expression above:
[tex]e^{i\theta}=\cos \theta+i\sin \theta[/tex]Then the exponential form of a number is equal to:
[tex]z=r\cdot e^{i\theta}=r\cdot(\cos \theta+i\sin \theta)=r\cos \theta+i\cdot r\sin \theta[/tex]And since we are talking about the same number then this expression must be equal to that given by a and b:
[tex]a+i\cdot b=r\cos \theta+i\cdot r\sin \theta[/tex]Equalizing terms without i and those with i we have two equations:
[tex]\begin{gathered} a=r\cos \theta \\ b=r\sin \theta \end{gathered}[/tex]Now let's use the data from the exercise:
[tex]\begin{gathered} r=\lvert z_1\rvert=2 \\ \theta=\theta_1=49^{\circ} \end{gathered}[/tex]Then we have:
