Your classmate is unsure about how to use side lengths to determine the type of triangle. How would you explain this to your classmate?

Answers

1) Equilateral Triangles: These triangles have the same side length and same angle for all sides. Knowing this, if the side lengths given are all the same, the triangle will be classified as an equilateral triangle. 

2) Isosceles Triangles: These triangles have two sides that have the same side length and one that is not the same. Given this, if the side lengths are all given, the triangle with two same sides are classified as isosceles triangle. 

3) Scalene Triangles: These triangles have all sides associated with a different value. If all side lengths are given and they have different values, this triangle would classify as a scalene triangle. 

Hope I helped :) 

Answer:

First, look at the side lengths a, b, and c, where c is the longest. Then take the sum of a squared and b squared and compare it to c squared. If they are equal, the triangle is a right triangle. If c squared is less than a squared plus b squared, the triangle is acute. If c squared is greater than a squared plus b squared, the triangle is obtuse.

Step 1) Original equation

Step 2) Add 7 to both sides

Step 3) Combine like terms

Step 4) Divide both sides by 2

Step 5) Simplify

Step 6) Apply the square root to both sides. The notation "sqrt" is shorthand for "square root"

Step 7) Use the rule that sqrt(x^2) = |x| for all real numbers x

Step 8) Use the rule that if |x| = k then x = k or x = -k for some fixed number k.

Is this function even, odd, or neither?

Answers

when a function is even, they have symmetry with respect to the y-axis, what does that mean?  well, the graph to the right-side of the y-axis is just a mirror image of the graph to the left-side of the y-axis.

when a function is odd, the symmetry is with respect to the origin, meaning, the graph to the right-side of the y-axis, is a mirror image of the one on the left-bottom-upside-down.  So, you take a photo of the right-side graph,flip it over the x-axis, and then flip it again over the y-axis.

How many real solutions does the equation have?
r2 – 94 = 0

Answers

Final answer:

The quadratic equation r² – 94 = 0 has two real solutions, as the discriminant is positive when applying the quadratic formula.

Explanation:

The question deals with the quadratic equation r2 – 94 = 0. To determine how many real solutions this equation has, we can rearrange it into the standard quadratic form ar2 + br + c = 0, where a = 1, b = 0, and c = -94. The real solutions of a quadratic equation are found using the quadratic formula, which is r = −b ± √(b2 - 4ac) / (2a). In this case, the discriminant (b2 – 4ac) becomes (02 – 4(1)(-94)) which simplifies to 376. This expression is a quadratic equation of the form at² + bt + c = 0, where the constants are a = 1, b = 0, and c = -94. To find the number of real solutions, we need to determine the discriminant, which is given by the formula: discriminant = b² - 4ac. If the discriminant is greater than zero, the equation has two real solutions. If the discriminant is equal to zero, the equation has one real solution. If the discriminant is less than zero, the equation has no real solutions. In this case, the discriminant is: 0 - 4(1)(-94) = 376. Since the discriminant is greater than zero, the equation r² - 94 = 0 has two real solutions. Since the discriminant is positive, this equation has two real solutions.

Final answer:

The equation has two real solutions.

Explanation:

This expression is a quadratic equation of the form  where the constants are To find the number of real solutions, we can use the discriminant, which is given by . If Δ > 0, there are two real solutions. If Δ = 0, there is one real solution. If Δ < 0, there are no real solutions. Let's calculate the discriminant:



Δ = 0² - 4(1)(-94) = 376



Since Δ > 0, the equation has

Generally speaking, using a ______ year's history of cash receipts and disbursements will be a satisfactory basis for projecting the future. Part of a year or full year

Answers

the answer is FULL
By collecting full year's history of cash, we could determine the amount of expense that company might need to continue the operation in the future.
This projection is made on the assumption that the company won't make any major change on its way of operation in next year's period.

Generally speaking, using a FULL year's history of cash receipts and disbursements will be a satisfactory basis for projecting the future.

Though a rough projection can be made in half year's data as well, but a good and solid projection can be made using full year's data. Almost all business run for a full year, so its good to project on an yearly basis. Like in this particular year the profits are this much, so we can project that in the next year we can see a higher profit.

Answer:

1   1/4 or 5/4 gallon per hour.

Step-by-step explanation:

Fuel used in 2 1/4 hour = 2  13/16 gallon

Fuel used in 9/4 hour = 45 / 16 gallon

Fuel used in one hour = [tex]\frac{\frac{45}{16}}{\frac{9}{4}}[/tex]

                                     = 5 / 4 gallon per hour = 1  1 /4 gallon per hour

Thus, teh fuel used in each hour is 1  1/4 gallon or 5 / 4 gallon.

A. (-30, 2)
B. (-2, 30)

Answers

Note that if we add each side of the 2 equations, y will cancel out:

-12x-y+(17x+y)=6+4

5x=10

x=2


Substituting x=2 in either of the equations, we find the value of y.

Let's use the first equation:

-12x-y=6

-24-y=6

-y=24+6

-y=30, so y=-30.

f(x) = x^2 + 24x + (24/2)^2 + 138 - (24/2)^2
f(x) = (x+12)^2 - 6

Answer:

(x +12)^2 - 6

Step-by-step explanation:

d/dx x^2 + 24x + 138 = 2x + 24

when 2x + 24 = 0, the gradient = 0

x = -12

f(-12) = -6

The side length AB is √(3²+4²) = 5.

Let's split up the shape in a square and a triangle.

If you introduce point E at (5,1) you see a square ABED with area 5*5=25.
What remains is a triangle with straight sides 5 and √((11-5)² + (1--7)²) = 10. So the triangle's area is 5*10/2 = 25.

This means the total area is 25+25=50.

What is the measure of angle a

Answers

Review the meaning of "straight angles."

Here 110 and A are "straight angles," and so 110 + A = 180   (degrees).

Then A = 70 degrees.

Answer:

m∠A = 70°

Step-by-step explanation:

The given figure is nothing but parallel lines cut by a transversal.

We use property of transversal to find the value of angle A.

Here ∠A and 110° are pair of interior angles on the same side.

The pair of interior angles on the same side add upto 180 degrees.

Therefore, ∠A + 110 = 180

Subtract 110 from both sides, we get

∠A + 110 - 110 = 180 -110

∠A = 70°

m∠A = 70°

Answers

Given the points P(-2, 7), Q(6, 8) and R(-1, -3), we find the quadratic equation of the form [tex]y=ax^2+bx+c[/tex] as follows:

Step 1:
We check to make sure that no pair of points is colinear (i.e. lie on the same line) by making that the slopes of the combinations of the line are not equal.

Slope of PQ = [tex] \frac{8-7}{6-(-2)} = \frac{1}{8} [/tex]
Slope of PR = [tex] \frac{-3-7}{-1-(-2)} = \frac{-10}{1} =-10[/tex]
Slope of QR = [tex] \frac{-3-8}{-1-6} = \frac{-11}{-7} = \frac{11}{7} [/tex]

Since, the slope of the lines are not equal, thus the points are not colinear nor parallel.

Step 2:
Substitute the x-values and the y-values of the given points into the quadratic equation formular to have three system of equations as follows:

[tex]a(-2)^2+b(-2)+c=7\Rightarrow 4a-2b+c=7 \ .\ .\ .\ (1) \\ \\ a(6)^2+b(6)+c=8\Rightarrow36a+6b+c=8\ .\ .\ .\ (2) \\ \\ a(-1)^2+b(-1)+c=-3\Rightarrow a-b+c=-3\ .\ .\ .\ (3)[/tex]

Step 3:

Therefore, the quadratic equation with the three given points is

[tex]y=\frac{81}{56}x^2-\frac{317}{56}x-\frac{283}{28}[/tex]
Final answer:

To find the quadratic equation from 3 points, use the method of substitution and solve the system of equations. Substituting the given points into the general quadratic equation will result in a system of equations that can be solved for the quadratic equation.

Explanation:

To find the quadratic equation from 3 points, we can use the method of substitution. Let's say the three points are (x1, y1), (x2, y2), and (x3, y3). We can substitute these points into the general quadratic equation, y = ax^2 + bx + c, to get three equations. Solving this system of equations will give us the values of a, b, and c, and thus the quadratic equation.

For example, let's say the three points are (1, 3), (2, 6), and (3, 11). Substituting these points into the general quadratic equation, we get the following equations:

3 = a(1^2) + b(1) + c

6 = a(2^2) + b(2) + c

11 = a(3^2) + b(3) + c

Solving this system of equations will give us the values of a, b, and c, and thus the quadratic equation.

Answers

The correct answer to the above question is, without any doubt, answer D. The two terms only differ in where the powers of ten are multiplied in the term. The actual values (5.4 and 18) that determine the overall digits of the result (972) do not change.
Final answer:

5.4 x 0.18 can be expressed as [tex](54 * 18) * (1/10 * 1/10)[/tex], where each 1/10 returns the decimal point stripped from 5.4 and 0.18 initially. So the correct answer is option B.

Explanation:

The appropriate approach to solving this question is by acknowledging how numbers with decimal points function on multiplication. To express 5.4 x 0.18 in another form, we can take the decimal points away and multiply the resultant figures, 54 and 18. Then, we introduce the decimal points back using fractions equivalent to 0.1 and 0.01 (that is, 1/10 and 1/100, respectively). Hence, the correct equivalent is option B: [tex](54 * 18) * (1/10 * 1/10).[/tex] The 1/10 accounts for the decimal in 5.4, and the other 1/10 accounts for the decimal in 0.18.

Paulo scored "x" on his first math test, then scored 10 points higher on his second, scored 5 points lower on the third than the second, and scored half as well on the fourth test as the second. if his average for the four tests is 75 points, what did he score on the second test?

Answers

We know that
[tex] \frac{x+(x+10)+(x+10-5)+ \frac{x+10}{2} }{4} = 75 [/tex]

Then we simplify to get this:
[tex] \frac{(3x+15)+ \frac{x+10}{2} }{4} = 75[/tex]

Then we get common denominators and add:
[tex] \frac{ (\frac{6x+30}{2})+ (\frac{x+10}{2}) }{4} = 75[/tex]
[tex] \frac{ \frac{7x+40}{2} }{4} = 75[/tex]

Then reciprocalize the main denominator and simplify:
[tex]\frac{7x+40}{2} * \frac{1}{4} = 75[/tex]
[tex] \frac{7x+40}{8} = 75[/tex]

And then solve for x:
[tex]7x + 40 = 600[/tex]
[tex]7x = 560[/tex]
[tex]x = 80[/tex]

Since he scored ten points higher than x (x is what he earned in the first test), we can add:
[tex]80 +10 = 90[/tex]

So, he got 90 points on his second test.
