PLEASE HELP AS SOON AS POSSIBLE!!!!!!!!!!!!!!!!!! |r+3| ≥7 solve the inequality (please show work and steps )

Answers

|r+3| = (r+3) when r ≥ -3 so for r ≥ -3
                        r + 3 ≥ 7
                               r ≥ 4
|r+3| = -(r+3) when r < -3 so for r < -3
                     -(r + 3) ≥ 7
                         r + 3 ≤ -7
                               r ≤ -10
The answer to this question is r ≤ -10, r ≥ 4
So the solution would be:
|r+3| = (r+3)
r + 3 ≥ 7
  r ≥ 4
|r+3| = -(r+3)
  -(r + 3) ≥ 7
   r + 3 ≤ -7
r ≤ -10
So the answer is r ≤ -10, r ≥ 4

Need help to write equations for 5, 6 & 7

The x-values go up by 1: -2, -1, 0, 1, 2
The y values are always 3 times the previous value.
This is an exponential function.

[tex] y = a(b)^x [/tex]

We need to find a and b.
Look at x = 0.
For x = 0, y = 4.

[tex] y = a(b)^x [/tex]

[tex] 4 = a(b)^0 [/tex]

Since b^0 = 1, this simplifies to

[tex] 4 = a [/tex]

Now we know a = 4. We have

[tex] y = 4(b)^x [/tex]

Look at x = 1. For x = 1, y = 12.

[tex] 12 = 4(b)^1 [/tex]

[tex] 12 = 4b [/tex]

[tex] b = 3 [/tex]

Now that we know a and b, we can write the function.

[tex] y = 4(3)^x [/tex]

Now that you have the function written out, notice the following.
In the exponential equation we found, the number raised to x
is the number you multiply each y value to get the next y value.
In this case, each y value is 3 times the previous one, so you have 3^x.
The way you find "a" in the exponential equation is to look at the y-coordinate
when x = 0. When x = 0, b^x is 1, so b^x drops out, and you get "a" equal to
the y-value. In this case, when x = 0, y = 4, so "a" is 4.
With b = 3, and a = 4, you can quickly write:
y = 4(3)^x.

A carpenter earns $18 an hour for a regular work week (40) hours. He earns time and a half for overtime. The weekly wage function is W(h)={                  18h                                         040} where h is the number of hours worked for the week. Find the wage if the carpenter worked 42.5 hours in the week

Answers

18×40=720 regular time
18×1.5=27 overtime per hour
27×2.5= 67.5 overtime

$720+$67.50=$787.50

Final answer:

To find the carpenter's weekly wage after working 42.5 hours, we calculate the regular pay for 40 hours at $18 per hour, which is $720, and then add the earnings from 2.5 hours of overtime at time and a half ($27 per hour), which is $67.5. The total weekly wage is $787.5.

Explanation:

To calculate the weekly wage of the carpenter who worked 42.5 hours, with $18 per hour for the first 40 hours and time and a half for overtime, we will use the wage function provided: W(h) = 18h for hours up to 40, and for hours above 40, it's (18 × 1.5) × (h - 40). Let's apply this to the 42.5 hours worked.

The carpenter's earnings for the regular 40 hours are $720 (which is 40 hours × $18). For the 2.5 hours of overtime, he earns time and a half, which is $27 per hour (18 × 1.5). The overtime earnings are $67.5 (2.5 hours × $27). So, the total wage is:

$720 + $67.5 = $787.5

Therefore, the carpenter's weekly wage for working 42.5 hours at the given rate is $787.5.

Line RS is tangent to circle Q at point R.


What is the measure of ∠SQR ?

Enter your answer in the box.

Answers

If the line RS is tangent to the circle, then it is at a 90 degree angle to the circle at the point of contact.

Now that we know 2 angles, we can find the 3rd:

180 - 90 - 32 = 58

Using the tangent and radius theorem, the measure of ∠SQR is 58°.

What is Circle Geometry??

From the question, we are to determine the measure of ∠SQR

In the given diagram, QR is a radius

By the tangent and radius theorem,

If a tangent and a radius meet at the point of tangency, then they are perpendicular to one another

∴ ∠QRS = 90°

∠SQR + ∠RSQ + ∠QRS = 180° (Sum of angles in a triangle)

∠SQR + 32° + 90° = 180°

∠SQR + 122° = 180°

∠SQR  = 180° -  122°

∠SQR  = 58°

Hence, the measure of ∠SQR is 58°.

Hamilton received a 75 on his algebra exam. The professor is allowing students to take a 7-question bonus quiz to improve their algebra exam score. Each question answered correctly on the bonus quiz will add 3 points to the exam score. Hamilton needs to receive at least a 90 on his exam score in order to make an "A" for the semester. If x represents the number of questions answered correctly on the bonus quiz, which of the following inequalities symbolizes this situation?


A. 3x + 75 < 90
B. 7x + 75 > 90
C. 3x + 75 > 90
D. 7x + 75 < 90




Answers

The answer is A.

Since each question answered right would add 3 points, the amount of questions answered correctly would be x. You then going to add that to his original score, 75. He needs at least a 90, so 90 is the lowest test grade he can afford. Therefore, 90 is should be the greatest number since there are no less than, equal to and such. Knowing that, the answer would be A

Hope this helps!

Final answer:

The correct inequality should be 3x + 75 ≥ 90 to indicate Hamilton needs at least 90 on his exam. The closest option given, which is not entirely accurate, is C. 3x + 75 > 90.

Explanation:

To determine the inequality that represents Hamilton’s situation, we need to calculate how many points he requires to reach a score of at least an “A”, which is 90. Each correct bonus question adds 3 points to his exam score of 75. We need to find the number of questions, x, Hamilton must answer correctly to achieve a total score of 90 or more. Therefore, the inequality that encompasses this scenario is 3x + 75 ≥ 90 because each correct answer contributes 3 points towards closing the 15-point gap between his current score and the desired score of 90.

However, the options given do not include the correct representation which would be 3x + 75 ≥ 90. Instead, the closest option is C. 3x + 75 > 90, which would imply that Hamilton must score more than 90, which is not a requirement for making an “A” (as “A” can include exactly 90).

A bin is constructed from sheet metal with a square base and 4 equal rectangular sides. if the bin is constructed from 48 square feet of sheet metal, then what is the largest volume of such a bin? what are its dimensions?

Answers

This is a problem of maxima and minima using derivative.

In the figure shown below we have the representation of this problem, so we know that the base of this bin is square. We also know that there are four square rectangles sides. This bin is a cube, therefore the volume is:

V = length x width x height

That is:

[tex]V = xxy = x^{2}y[/tex]

We also know that the bin is constructed from 48 square feet of sheet metal, so:

Surface area of the square base = [tex]x^{2}[/tex]

Surface area of the rectangular sides = [tex]4xy[/tex]

Therefore, the total area of the cube is:

[tex]A = 48 ft^{2} = x^{2} + 4xy[/tex]

Isolating the variable y in terms of x:

[tex]y = \frac{48- x^{2} }{4x}[/tex]

Substituting this value in V:

[tex]V = x^{2}( \frac{48- x^{2} }{x}) = 48x- x^{3} [/tex]

Getting the derivative and finding the maxima. This happens when the derivative is equal to zero:

[tex]\frac{dv}{dx} = 48-3x^{2} =0[/tex]

Solving for x:

[tex]x = \sqrt{\frac{48}{3}} = \sqrt{16} = 4[/tex]

Solving for y:

[tex]y = \frac{48- 4^{2} }{(4)(4)} = 2[/tex]

Then, the dimensions of the largest volume of such a bin is:

Length = 4 ft
Width =  4 ft
Height = 2 ft

And its volume is:

[tex]V = (4^{2} )(2) = 32 ft^{3}[/tex]

What is cos 45? Please HELP !!!

Answers

Answer:

A) Cos ( 45) = [tex]\frac{1}{\sqrt{2}}[/tex].

Step-by-step explanation:

Given  : Triangle 90 -45 -45 .

To find : What is cos 45.

Solution : We have given

Triangle 90 -45 -45  

Hypotenuse = √2 ,

Adjacent side to 45 degree = 1 .

By the trigonometric ratio : cosine is the ratio of the adjacent side to angle  to the hypotenuse .

Cos ( theta) = [tex]\frac{Adjacent}{hypotenuse}[/tex].

Plug the values  Hypotenuse = √2 , Adjacent side to 45 degree = 1 .

Cos ( 45) = [tex]\frac{1}{\sqrt{2}}[/tex].

Therefore, A) Cos ( 45) = [tex]\frac{1}{\sqrt{2}}[/tex].

The cosine of 45° is √2 / 2.

In a triangle with angles of 90°, 45°, and 45°, we can use the trigonometric functions to find the ratios of the sides.

In this case, we want to find the cosine of 45°.

The cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse.

In the given triangle, the adjacent side to the 45° angle is 1, and the hypotenuse is √2.

Using the formula for cosine, we have:

cos 45° = adjacent side / hypotenuse

Substituting the values, we get:

cos 45° = 1 / √2

To rationalize the denominator, we multiply both the numerator and denominator by √2:

cos 45° = (1 / √2) * (√2 / √2) = √2 / 2

Therefore, the cosine of 45° is √2 / 2.

how many times greater is one hour than one minutes Mounds of History Elizabeth Kibler1Looking at the Etowah Indian Mounds Historic Site in Georgia is like taking a trip into history. Huge, green mounds sprout up from the grassy earth. The impressive mounds give visitors a feeling of mystery. The Etowah Indian Mounds Historic Site in Georgia is one of the most well preserved examples of Native American society in the United States. This historic site is 54 acres of what was once a Native American town. The Mounds3The Etowah Indian Mounds Historic Site, located near the Etowah River, has six mounds. Three of the moundscalled A, B, and Care the most famous features of the site. Native Americans built the mounds beside two, open plazas. The mounds have four sides and flat tops. Native Americans used steps to get to the tops of the mounds. They also built a ditch that served as a protective barrier around the mounds. Native Americans built the mounds for several reasons. They used the mounds as platforms for building, burial grounds, and areas for religious activities. The main mounds served as the center of the town. The other members of the town lived scattered for many miles around the mounds. Scientific Research5Scientists who study ancient cultures discovered much information about the mounds. They believe that Mound A at Etowah was reserved for the chief of the area. The chief of the town had his home on the mound. The other citizens of the town lived around this mound. The closer a person lived to Mound A, the more significant he or she was in the society. Mound A reaches about 60 feet high. It is also more than 300 square feet wide at its base. Some scientists believe that every time a chief died, a new layer was added to mound. Then, a new house was built on the top. 6The only Etowah mound to be fully dug up and researched is Mound C. Mound C was used as a burial mound. Inside Mound C, scientists found jewelry, clothing, and other important relics. Mississippian Culture7The Etowah Indian Mounds are remnants of an interesting society. The builders of these mounds were part of the Mississippian culture. This group of Native Americans lived in parts of North America from 800 A.D. until the arrival of European explorers. People of the Mississippian culture built these mounds between 1000 B.C. and 1550 A.D.8The Mississippians living in and around Georgia first encountered European explorers in the 1500s. Unfortunately, the Native Americans were not protected against the ailments brought by these strangers. Illness put the already-declining population on dangerous ground.
