Final answer:

The correct expression to find the temperature difference between the low and high temperatures when the temperature rose as much above zero as it was below zero is 5 + 5 degrees, which equals 10 degrees in total.

Explanation:

The question involves finding the difference in temperature from a low of -5 degrees Fahrenheit to a high that is as many degrees above zero as the low was below zero. To calculate the difference, we consider the increase in temperature from the low to 0 degrees, which is 5 degrees, and then the additional increase to the high temperature, which is also 5 degrees above zero. Therefore, the total change in temperature is 5 degrees (to get to zero) plus another 5 degrees (to reach the high), totaling 10 degrees.

The correct expression to find the number of degrees between the low and high temperatures would be C. 5 + 5, representing the increase from -5 degrees to 0, and from 0 to +5 degrees, respectively.

Answer: A. Based on the law of syllogism, if two lines meet at a 90 angle, then they have opposite reciprocal slopes.

Step-by-step explanation:

Law of Syllogism which is also known as reasoning by transitivity is a valid argument method of a deductive reasoning that follows a sequence.

Its similar to the transitive property of equality, which states that if a=b and b=c then a=c

The given statement :  If two lines meet at a 90 angle, they are perpendicular. If two lines are perpendicular, they have opposite reciprocal slopes.

let a →" two lines meet at a 90 angle"

b→ "two lines are perpendicular are perpendicular"

c→" two lines have opposite reciprocal slopes"

Since a→b and b→c

Therefore by law of syllogism, a→c

i.e. If two lines meet at a 90 angle, then they have opposite reciprocal slopes.

Aswer:  9 /  4  sqrt 3

Solution:

Perimeter: P=9 inch

Area: A=?

A=(1/4) sqrt(3) L^2

Side of the triangle: L

We need the side "L" of the triangle:

We know: P=3 L

Replacing the perimeter in the equation above:

9 inch=3 L

Solving for L: Dividing both sides of the equation above by 3:

(9 inch) / 3 = 3 L /3

3 inch = L

L = 3 inch

Replacing L=3 inch in the formula of Area:

A=(1/4) sqrt(3) L^2

A=(1/4) sqrt(3) (3 inch)^2

Squaring:

A=(1/4) sqrt(3) (9 inch^2)

Multiplying:

A=(1*9)/4 sqrt(3) inch^2

A=9/4 sqrt(3) inch^2

Answer:

9√3/4

or

9/4√3

Step-by-step explanation:

P=3a=9⇒a=3 inches.

The area of the equialteral triangle is

A=\dfrac{a^2\sqrt{3}}{4}=\dfrac{3^2\sqrt{3}}{4}=\dfrac{9\sqrt{3}}{4}\ \text{sq. in}.A=4a23=4323=493 sq. in.

Answer:

This is an Obtuse triangle.

Step-by-step explanation:

A Equilateral Triangle is a triangle where all sides are equal. Here all sides are different so it is not an Equilateral Triangle.

Isosceles triangle is a triangle that has 2 sides that are equal. Here all sides are different therefore this is not an Isosceles triangle.

A right angled triangle is a triangle whose sides satisfy the following equality.

Lets say A triangle has sides a, b and c. Where c is the highest value.

Then, [tex]a^{2} +b^{2} =c^{2}[/tex]

Lets substitute the values to the above equation to see whether it the triangle we are given satisfies the above equality,

[tex]7^{2} +15^{2}[/tex] = [tex]49+225[/tex]=[tex]274[/tex]

[tex]17^{2} =289[/tex]

Therefore, [tex]7^{2} +15^{2}[/tex] ≠[tex]17^{2}

So it is not a Right Angled Triangle.

If the sum of squares of the shorter sides is greater than the square of the longer side then it is an Acute angle if not it is an obtuse angle.

[tex]7^{2} +15^{2}[/tex] = [tex]274[/tex]≤[tex]17^{2} =289[/tex]

Therefore, This is an Obtuse triangle.

Answer:

  x  <  6.4  

Step-by-step explanation:

given,

       -8 - 5 x + 2 > -38

           - 5 x - 6 > -38

adding both side by 6

           - 5 x - 6 + 6  > -38 + 6

             - 5 x  > -32

multiplying both side by (-1)

                5 x  <  32        

on multiplying by negative sign the inequality direction changes

                  x  <  6.4  

the graph is shown in the figure attached below. the shaded region shows the required area.

A compound inequality is a sentence with two inequality statements joined either by the word “or” or by the word “and.” “And” indicates that both statements of the compound sentence are true at the same time.

“Or” indicates that, as long as either statement is true, the entire compound sentence is true.

Now as shown in the graph, the solution inequality of the graph is :

x > 3 and x < 5   [please note, circles in the graph indicate exclusion, dots indicate inclusion. in the graph given circles are shown, so it depicts exclusion]

Now let's solve each option to find if it fits in with the above inequality

Option 1 : 2x-4 > 6 or 3x < 9

⇒ x > 5 or x < 3

Option 2 : 2x - 4 < 6 and 3x > 9

⇒ x < 5 and x > 3

Option 3 : 3x + 8 > -7 or -4x < 12

⇒ 3x > -15 or x < -3

⇒ x > -5 or x < -3

Option 4 : 3x + 8 < -7 and -4x > 12

⇒ 3x < -15 and x > -3

⇒ x < -5 and x > -3

So the compound sentence in option 2 : 2x - 4 < 6 and 3x > 9

4x+10 >= 11

4x+10-10 >= 11-10 .... subtract 10 from both sides

4x >= 1

4x/4 >= 1/4 .... divide both sides by 4

x >= 1/4

x >= 0.25

This means  x must be 0.25 or larger. The next integer closest to 0.25, that is above 0.25, is the value 1.

So x = 1 is the smallest integer solution possible.

Let x = the smaller number.

Let 4+3x = the larger number.

So, 28 = 4+3x - x

24 = 2x

x = 12.

The smaller number is 12, now we need to find the larger number,

4+3(12)

40

So, the numbers are 12 and 40.

The equation can be solved by setting up two equations based on the information given, and then substitifying and simplifying the equations to solve for the two numbers. The two numbers are 12 and 40.

The subject of this question is dealing with equations in mathematics. To problem-solve this, we can first form an equation based on the information given: The larger number is equal to 'four more than three times the smaller number' and 'the difference between the two numbers is 28'.

So we can set up two equations:

By substituting the first equation into the second, it resolves as:

3S + 4 - S = 28

which simplifies to:

2S = 24

So, the smaller number S = 24/2 = 12. Substituting S = 12 into the first equation gives:

L = 3*12 + 4 = 36 + 4 = 40

So the two numbers are 12 and 40.

So here is how it would go

Isolate the x. Treat the less than sign as equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 47 from both sides

4x + 47 (-47) < 7 (-47)

4x < -40

Next, divide 4 from both sides

(4x)/4 < (-40)/4

x < -40/4

x < -10

x < -10 is your answer

ISS completes 21,900 orbits around the Earth in four years.

To calculate how many times the International Space Station (ISS) orbits the Earth in 4 years, we would set up a column addition problem where we add the number of orbits per year 5475 times for each of the four years. Here is the problem set up for column addition:

 5475
+ 5475
+ 5475
+ 5475
------

When we add these numbers, the total will give us the number of orbits completed in four years.

The addition is as follows:

 5475
+ 5475
+ 5475
+ 5475
------
21900

Therefore, the ISS completes 21,900 orbits around the Earth in four years.

Answers:

a. The company needs to sell 100 units to reach the maxmum profit.

b. The company's maximum profit is $5,000.

Solution:

a. How many unit does the company need to sell to reach the maximum profit?

p(x)=-0.5x^2+100x

This is a quadratic equation, and its graph is a parabola vertical (because the veriable "x" is square). Comparing with the general form:

p(x)=ax^2+bx+c; a=-0.5, b=100, c=0

a=-0.5<0 (negative), then the parabola opens downward, and it has a maximimun value (maximum profit) at its vertex.

We can find the abscissa of the vertex (units that the company needs to sell to reach the maximum profit using the following formula:

x=-b/(2a)

Replacing b by 100 and a by -0.5 in the formula above:

x=-100/[2(-0.5)]

x=-100/(-1)

x=100

The company needs to sell 100 units to reach the maximum profit.

b. What's the company's maximum profit?  

To determine the maximum profit we substitute the value of "x" obrained in part "a" in the quadratic equation:

x=100→p(100)=-0.5(100)^2+100(100)

p(100)=-0.5(10,000)+10,000

p(100)=-5,000+10,000

p(100)=5,000

The company's maximum profit is $5,000.

n = 8

the sum to n terms of a geometric sequence is

[tex]S_{n}[/tex] = [tex]\frac{a(1-r^{n )} }{1-r}[/tex]

where a is the first term and r the common ratio

here a = 16 and r = [tex]\frac{64}{-32}[/tex] = [tex]\frac{-32}{16}[/tex] = - 2

[tex]S_{n}[/tex] = ( 16( 1 - ( - 2 )^n )/1 - (- 2 )) = - 1360

[tex]\frac{16}{3}[/tex] ( 1 - (- 2 )^n ) = - 1360

multiply both sides by [tex]\frac{3}{16}[/tex]

1 - (- 2 )^n = - 255

- (- 2 )^n = - 256

)-2)^n = 256

note that [tex]2^{8}[/tex] and [tex](-2)^{8}[/tex] = 256

hence n = 8
