Answer:
3x + 2 = 14
3x + 2 - 2 = 14 - 2
3x = 12
3x/3 = 12/3
x = 4
Step-by-step explanation:
3x + 2 = 14
subtract 2 from both sides
3x + 2 - 2 = 14 - 2
combine like terms.
3x = 12
divide both sides by 3
3x/3 = 12/3
x = 4

Read the passage. Which statement best describes how Belle changes over the course of the story?
Riding a Bicycle
It was a bright Sunday morning when Belle woke up with the biggest smile on her face. She had been looking forward to this day for a long time. Her father was going to teach her to ride a bicycle. She dressed quickly and gulped down her breakfast.
After breakfast, Belle’s father showed her the different parts of a bike. Then he said he would hold onto the back of the bike while she peddled. But Belle’s excitement got the better of her. She said she wanted to try riding by herself. Her father let go. Belle quickly lost her balance and crashed to the ground. The fall dazed her. She grumpily agreed to let her father keep holding the bike while she rode.
Every once in a while, he would let go. The moment he did, Belle would lose her balance and topple over. Her father explained that this was perfectly normal. He said that all first-time riders fall. Even so, Belle’s mood darkened with each fall. After a while, she wanted to give up and return home.
Belle’s father tried to talk her out of quitting. He pointed toward some other children biking nearby. He showed her how happy they looked as they rode their bicycles. He told her she needed to keep trying. With a little more effort, she would soon enjoy riding just like the other children. His words gave Belle the determination to keep going.
After several more failed tries, Belle finally got the hang of it. She began gently peddling by herself, beaming with pride. She had finally done it! That night, she went to bed with a couple of bruises and cuts. But she had an even bigger smile on her face than she’d had in the morning. She would forever remember this day and the lesson she learned about never quitting.
A.
Belle starts showing more trust in her father as he teaches her how to ride a bike.
B.
Belle becomes less excited as the story goes on, until her excitement for bike riding disappears.
C.
Belle learns both how to ride a bike and how important it is not to give up.
D.
Belle gets hurt from falling off her bike, which scares her away from bike riding for good.

Nola hiked down a trail at a steady rate for 10 minutes. Her change in elevation was −190 feet. Then she continued to hike down for another 20 minutes at a different rate. Her change in elevation for this part of the hike was −200 feet. During which portion of the hike was her rate of change in elevation greater? Complete the explanation. Her rate was faster in the (Select: First, Second) part of the hike, because her heart rate was ____ ft/min in the first part and ___ ft/min in the second part.
Answers
Answer:
Her rate was faster in the FIRST because her rate was - 19 ft/ minutes in the FIRST PART and - 10ft/minute in the SECOND part
Step-by-step explanation:
Portion 1
Time taken to hike down = 10 minutes
Change in elevation = - 190 ft
Portion 2
Hiked down for further 20 minutes
Change in elevation = - 200ft
During which portion of the hike was her rate of change in elevation greater?
Rate of change in elevation :
Change in elevation / time
Portion 1:
Rate of change in elevation :
Change in elevation / time
- 190 ft / 10 minutes = - 19 ft/minutes
Portion 2:
Rate of change in elevation :
Change in elevation / time
- 200 ft / 20 minutes = - 10 ft/minutes
Her rate was faster in the FIRST because her rate was 19 ft/ minutes in the FIRST PART and 10ft/minute in the SECOND part

At the end of week one, a stock had increased in value from $5.75 a share to $7.50 a share.Find the percent of increase at the end of week one to the nearest tenth of a percent.At the end of week two, the same stock had decreased in value from $7.50 to $5.75.Is the percent of decrease at the end of week two the same as the percent of increase at the end of week one?Justify your answer.
Answers
First, we will find the increase. I don't think it's any of the 3 formulas listed.
The formula I'll be using is Increase = Increased value - Original value
Let x be increase.
x = $7.50 - $5.75
x = $1.75
We then divide the increase by the original value.
Percent of increase = Increase/Original value
Let x be percent of increase.
x = $1.75/$5.75
x is approximately 0.30437
To turn a decimal into a percent, multiply it by 100.
0.30437 x 100 = 30.437
30.437 can be rounded to 30.4
The percent of increase at the end of week one is 30.4%
At the end of week two, the same stock had decreased in value from $7.50 to $5.75.We will first need to find the percent of decrease.
The formula will be Decrease = Original value - Decreased value
Let x be decrease
x = $7.50 - $5.75
x = $1.75
We then divide the decrease with the original value.
Percent of decrease = Decrease/Original Value
Let x be percent of decrease
x = $1.75/$5.75
x is approximately 0.30437
To turn a decimal into a percent, multiply it by 100.
0.30437 x 100 = 30.437
30.437 can be rounded to 30.4
The percent of decrease at the end of week one is 30.4%
Is the percent of decrease at the end of week two the same as the percent of increase at the end of week one? Justify your answer.No because the full percent of increase at the end of week one is 100% + 30.4% so that would be like a 130.4% increase while at the end of week two, it would be 130.4% - 30.4% and that would lead us back to 100%.
A packaging company makes package peanuts in two containers, rectangular prisms and cylinders. The rectangular prism has a length of 6 feet, a width of 3 feet, and a height of 5 feet. The cylinder of peanuts has a diameter of 7 feet and a height of 10 feet. How many rectangular prisms contain the same amount of peanuts as one cylinder container? Round your answer to the nearest tenth.
Answers
Answer:
4.3
Step-by-step explanation:
length = 6 feet
width = 3 feet
height = 5 feet
Volume of rectangular prism = length × width × height
= (6 × 3 × 5) feet
= 90 cubic feet
cylinder of peanuts has a diameter of 7 feet and a height of 10 feet
Volume of a cyclinder = πr^2h
π = 3.14
r = diameter / 2
= 7/2 = 3.5 feet
h =10 feet
Volume of a cyclinder = πr^2h
= 3.14 × (3.5)^3 × 10
= 3.14 × 12.25 × 10
= 384.65 cubic feet
How many rectangular prisms contain the same amount of peanuts as one cylinder container = volume of cylinder container / volume of rectangular prism container
= 384.65 / 90
= 4.274
To the nearest tenth = 4.3

The paraboloid z = 3 − x − x2 − 2y2 intersects the plane x = 1 in a parabola. Find parametric equations in terms of t for the tangent line to this parabola at the point (1, 3, −17). (Enter your answer as a comma-separated list of equations. Let x, y, and z be in terms of t.
Answers
Answer:
the required parametric equation is:
x = 1
y = t + 3
z = -12t - 17
Step-by-step explanation:
From the given information:
We are to express x,y, and z in terms of t.
The purpose of this question is to find the parametric equations in terms of t.
Given that the tangent line related to the parabola is the point (1,3, -17)
Provided that the paraboloid z = 3 - x - x² - 2y² intersect the plane x = 1 in a paraboloid; then:
z = 3 - 1 - (1)² - 2y²
z = 1 - 2y²
Suppose y = t, then the parametrization is given by:
(x (t), y(t), z(t) ) = (1, t, 1 - 2t²)
(x' (t), y'(t), z'(t) ) = (0,1, -4t)
At the point (x,y,z) = (1,3, -17)
For t (=y) = 3
Hence, (x'(3),y'(3),z'(3)) = (0,1, -12)
Therefore, the equation of the tangent line can be expressed as:
[tex]\dfrac{x-1}{0}=\dfrac{y-3}{1}=\dfrac{z-(-17)}{-12}=(t)[/tex]
x - 1 = 0, y -3 = t, z + 17 = -12t
x = 1, y = t + 3 , z = -12t - 17
Thus, the required parametric equation is:
x = 1
y = t + 3
z = -12t - 17

To find:
The two values of [tex]\theta = ?[/tex]
Solution:
By given equation:
[tex]\theta = tan^{-1}(0.4226)[/tex]
[tex]\theta[/tex] can be equal to [tex]\approx 20.91^\circ[/tex]
Also, we know the property that, [tex]tan\theta[/tex] is positive in the 3rd quadrant.
and following is also true:
[tex]tan\theta = tan(180^\circ+\theta)[/tex]
Therefore, another value possible for [tex]\theta[/tex] can be:
[tex]\theta =180^\circ+22.91\\\Rightarrow \theta \approx 202.91^\circ[/tex]
Therefore, the answer is:
[tex]22.91^\circ, 202.91^\circ[/tex]
