using a table of value determine the solution to the equation below to the nearest fourth of a unit

2^(-x) + 1 = 5^x + 2

x= -1.50
x= 2.50
x= -0.50
x= 0.75

Answers

For finding the solution to something like this, it makes sense to write a function of x that is zero at the solution value. That function might be obtained by subtracting the right side from the equation.
  f(x) = (2^-x +1) - (5^x +2)
Now, we want to find x so that f(x) = 0.

For the offered choices, we get
  f(-1.50) ≈ 1.74
  f(-0.50) ≈ -0.03
  f(0.75) ≈ -3.75
  f(2.50) ≈ -56.72

The obvious choice is
  x = -0.50

A basketball is thrown with an initial upward velocity of 30 feet per second from a height of 6 feet above the ground. The equation h=-16t^(2)+30t+6 models the height in feet t seconds after the basketball is thrown. After the ball passes its maximum height, it comes down and then goes into the hoop at a height of 10 feet above the ground. About how long after it was thrown does it go into the hoop?

Answers

For this case we have the following equation:
 h = -16t ^ (2) + 30t + 6
 We substitute the value of h = 10 in the equation:
 10 = -16t ^ (2) + 30t + 6
 Rewriting we have:
 0 = -16t ^ (2) + 30t + 6-10
 0 = - 16t ^ (2) + 30t - 4
 We look for the roots of the polynomial:
 t1 = 0.144463904
 t2 = 1.730536096
 "the ball passes its maximum height, it comes down and then goes into the hoop". Therefore, the correct root is:
 t = 1.730536096
 Answer:
 It goes into the hoop after:
 t = 1.73 seconds

cylinder A has a volume of 360 cm3. Cylinder B has a base and height identical to that of cylinder B, but leans to the right in such a way that its slant is greater than 4 cm. what is the volume of cylinder B

Answers

If the height is measured between the parallel ends of the cylinder, the volume is identical:
  360 cm³.

_____
If the "height" is measured along the central axis of the cylinder, there is insufficient information to determine the volume.

The slant length of a prism (even a cylindrical one) is immaterial. What matters to the volume is the area of the base and the distance between the planes of the bases (height).

Which type of study contains a treatment?

Sample.
Experiment.
Survey.
Observational study.

Answers

Typically, in an experiment there are two groups. One group is called the control group. The other group is the experimental group. This second group receives some sort of treatment. The control group does not. The idea is to see if the treatment has an effect on those who receive it by comparing them to a comparable group that does not receive the treatment.

So the answer is experiment.
The type of study that contains a treatment is called EXPERIMENTAL STUDY.
An experimental set up usually involved random assignment of variables into different group and manipulation of a particular variable while others are controlled. This type of study is usually done to determine the effect of one variable on the outcome of another variable. The experimental set up is usually made up of control and treatment groups.

PLEASE HELP!!!!!! WHICH OF THE FOLLOWING IS A CORRECT EQUATION FOR THE LINE PASSING THROUGH THE POINT (-2 1) AND HAVING SLOPE M = 1/2

Answers

The answer for this equation is A and B.
Answer choice A is in slope-intercept (y = mx+b) form. The slope of the line is the number in front of the x, so in this case it's [tex] \frac{1}{2} [/tex]. Now, just plug in the given point to see if the equation is satisfied: 

[tex]1= \frac{1}{2} (-2)+2[/tex]
[tex]1= -1+2[/tex]
[tex]1= 1[/tex]

It works, so answer choice A works.

Answer choice B is in slope-intercept (y = mx+b) form. The slope of the line is the number in front of the x, so in this case it's -2. Answer choice B has the wrong slope, so eliminate B.

Answer choice C is in standard form. Rearrange it to slope-intercept form:

[tex]x-2y=-4[/tex]
[tex]-2y=-x-4[/tex]
[tex]y= \frac{1}{2} x+2[/tex]

Same as A, so answer choice C works.

Answer choice D is in point-slope form: y - y1 = m(x - x1). If you know this form well, you should be able to see that the given equation satisfies both the slope and point requirement. If you don't know the form well, try putting it into slope-intercept:

[tex]y-1= \frac{1}{2} (x+2) [/tex]
[tex]y-1= \frac{1}{2} x+1 [/tex]
[tex]y= \frac{1}{2} x+2 [/tex]

Same as A, so answer choice D works.

From the figure we are given that the measure of angle U is equal to 85°. With this, we can conclude that the arc intercepted by the angle which is the arc DKC will have a measure that is twice its value. 

     m(DKC) = 2(85°) = 170°

The total measure of the arc in a circle is equal to 360°. Hence,

     m(DKC) + m(DUC) = 360°

Substituting the known value,
      170° + m(DUC) = 360°

The value of m(DUC) is equal to 190°. The measure of the angle K is half this value.

Good Treads and Speed Tracks manufacture tires. Good Treads claims that their tires last longer than Speed Tracks tires. A car company decided to test Good Tread's claim. They purchased 20 sets of Good Tread's tires and 20 sets of Speed Track's tires. They tested the lifetime of each tire by simulating 1,000 miles of driving conditions for each set of tires each day. At the end of each day, they measured the tread on each of the tires. Once the tire tread drops below minimum safe tread depth, the tire is considered to have passed its lifetime.

After observing the lifetime of each tire, the car company reported that the average lifetime of a Good Treads tire is 55,000 miles and the average lifetime of a Speed Tracks tire is 65,000 miles.

Given the car company's report, what conclusion can be made regarding the average lifetime of Good Treads and Speed Tracks tires?
There is not enough information to make any conclusions from the car company's report.


Good Treads' claim is false; therefore, it can be concluded that Speed Tracks tires last longer than Good Treads tires.

Answers

Good Treads' claim is false; therefore, it can be concluded that Speed Tracks tires last longer than Good Treads tires.

D

The car company's report provides evidence that Speed Tracks tires have a longer average lifetime compared to Good Treads tires. Therefore, we can conclude that Good Treads' claim that their tires last longer is false.

Based on the car company's report, we can conclude that Good Treads' claim that their tires last longer than Speed Tracks' tires is false. The average lifetime of a Good Treads tire is reported to be 55,000 miles, while the average lifetime of a Speed Tracks tire is reported to be 65,000 miles.

To reach this conclusion, we compare the average lifetimes of the two tire brands. Since the car company tested 20 sets of each brand's tires and measured the tread on each tire after simulating 1,000 miles of driving conditions, we can assume that these results are representative.

By comparing the average lifetimes, we see that the average lifetime of Speed Tracks tires is greater than the average lifetime of Good Treads tires. Therefore, we can conclude that Speed Tracks tires last longer than Good Treads tires, contradicting Good Treads' claim.

In conclusion, the car company's report provides evidence that Speed Tracks tires have a longer average lifetime compared to Good Treads tires. Therefore, we can conclude that Good Treads' claim that their tires last longer is false.

The ratio of the lengths of corresponding sides of two similar octagons is 8:9. what is the ratio of their perimeters? *

Answers

The ratio of perimeters is the same as the ratio of the corresponding sides: 8:9.

_____
Any corresponding length measures of the similar figures will have the same ratio.

The ratio of the perimeters of the two similar octagons is the same as the ratio of the lengths of their corresponding sides, which is 8:9.

When dealing with similar polygons, such as octagons in this case, the ratio of the lengths of corresponding sides directly determines the ratio of their perimeters. Since the sides of the octagons are proportional, with a specific ratio of 8:9, we can infer that the perimeters of the octagons will also have the same ratio. This is due to the perimeter being the sum of the lengths of all sides of the polygon.

Therefore, if one side of the first octagon is scaled up by a factor of 8, the entire perimeter will be scaled by the same factor. Correspondingly, if one side of the second octagon is scaled up by a factor of 9, its entire perimeter will also reflect that scaling. Given that the ratio of the lengths of corresponding sides is 8:9, the ratio of their perimeters will also be 8:9.

Indicate the general rule for this sequence. Find a 1 and the common difference. a 4 = 18 a 7 = 9

Answers

Final answer:

The general rule for the sequence is an = -9 + (n-1)(9). The first term (a1) is -9 and the common difference is 9.

Explanation:

Sequence Analysis:

To find the general rule for a sequence, we need to determine the pattern or relationship between the terms. In this case, we are given a4 = 18 and a7 = 9. To find the common difference, we subtract the two terms: 18 - 9 = 9. So, the common difference is 9. To find a1, we can use the formula: an = a1 + (n-1)d, where n is the term number and d is the common difference. Substituting n = 4, a4 = 18, and d = 9, we can solve for a1. 18 = a1 + (4-1)(9), which gives us a1 = 18 - 3(9) = 18 - 27 = -9. Therefore, the general rule for this sequence is an = -9 + (n-1)(9). The first term (a1) is -9 and the common difference is 9.

a^1 = 27

Because your friends stayed in bed instead of helping you with the breakfast, you agree to split the £248 hostel bill to the ratio of: 3:3:2 with you paying the least. How much will you have to pay?

Answers

Final answer:

The question posed is about the concept of ratio, you are required to divide £248 according to the ratio 3:3:2. Each part of the ratio is worth £31, thus you will have to pay for two parts, hence, your total responsibility is £62.

Explanation:

The subject of this question is ratio. In the given problem, you need to distribute £248 hostel bill into the ratio of 3:3:2. Firstly, you add the three parts of the ratio which equals to 8 (3+3+2). Now, to find out how much each part is worth you need to divide the total sum, which is £248, by the total number of parts, which is 8. This gives you the value for one part, which is £31 (248 ÷ 8).

Given that you have to pay the least, which corresponds to 2 parts, you multiply £31 by 2, thus you have to pay £62 (31 * 2).
