What is the slope of the line that goes through (2, 5) and (-6, -2) ?

Answers

Answer 1

Answer:
slope = 7/8

Explanation:
Slope of the line can be calculated using the following equation:
slope = [tex] \frac{y2 - y1}{x2 - x1} [/tex]

The two points given are:
(2,5) representing (x1 , y1)
(-6,-2) representing (x2 , y2)

Substitute with the points in the above equation to get the slope as follows:
slope = [tex] \frac{-2 - 5}{-6 - 2} [/tex] = 7/8

Hope this helps :)

The chemical formula for lithium phosphide is Li3P. Which best describes this ionic compound?

Answers

Lithium ions have 1 positive charge, and phosphorus ions have 3 negative charges.

When lithium and phosphorus combine to form lithium phosphide, three lithium cations (Li+) combine with one phosphide anion (P₃-) to balance the charges and form a neutral compound, Li₃P.

What is Ionic compound?

an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding.

The correct description of the ionic compound lithium phosphide, with the chemical formula Li3P, is "Lithium ions have 1 positive charge, and phosphorus ions have 3 negative charges."

This is because lithium is a Group 1A element, which means it has one valence electron that it tends to lose in chemical reactions to form a cation with a charge of +1.

Phosphorus, on the other hand, is a Group 5A element, which means it has five valence electrons and tends to gain three electrons to form an anion with a charge of -3.

Thus, When lithium and phosphorus combine to form lithium phosphide, three lithium cations (Li+) combine with one phosphide anion (P₃-) to balance the charges and form a neutral compound, Li₃P.

The angle bisector of ∠ACD in rhombus ABCD makes a 64° angle with the diagonal BD . Find the measure of ∠BAD.

Answers

In a rhombus, the diagonals are perpendicular bisectors of each other, meaning they divide each other into two equal parts at a right angle. Let's denote the measure of ∠BAD as x degrees. The measure of ∠BAD is [tex]$ 26^\circ $[/tex].

Since the angle bisector of ∠ACD makes a 64° angle with the diagonal BD, and BD bisects ∠ACD, then ∠ACB = 64° as well. Additionally, since ABCD is a rhombus, opposite angles are equal. Therefore, ∠ABD = ∠ACB = 64°.

Now, considering triangle ABD, we know that the sum of angles in a triangle is 180°. Thus:

[tex]\[ \angle BAD + \angle ABD + \angle ADB = 180^\circ \][/tex]

Substituting the known values:

[tex]\[ x + 64^\circ + 90^\circ = 180^\circ \][/tex]

[tex]\[ x + 154^\circ = 180^\circ \][/tex]

[tex]\[ x = 180^\circ - 154^\circ \][/tex]

[tex]\[ x = 26^\circ \][/tex]

So, the measure of ∠BAD is [tex]$ 26^\circ $[/tex].

To summarize:

1. The angle bisector of ∠ACD in the rhombus makes a 64° angle with diagonal BD.

2. By the properties of a rhombus, ∠ACB = 64° as well.

3. Since opposite angles in a rhombus are equal, ∠ABD = ∠ACB = 64°.

4. In triangle ABD, the sum of angles is 180°.

5. Solving for ∠BAD, we find [tex]$ 26^\circ $.[/tex]

Which is the measure of the reference angle for 227 degrees

Answers

47 degrees

hope this helps<3

Geometrically, the reference angle is the smallest angle between the terminal ray and the x-axis.

Algebraically, the reference angle for X is the smaller of (X mod 180°) and (-X mod 180°).

Here, that would be
.. min(227 mod 180, -227 mod 180)
.. = min(47, 133)
.. = 47 . . . . degrees

_____
"X mod 180" means you subtract the largest multiple of 180 that is smaller than X.
Then 227 mod 180 = 227 -180 = 47
and -227 mod 180 = -227 -(-360) = 133.

Amount = $980

Answers

1)
Principal Amount = P = $980
Interest rate = r = 8% = 0.08
Compounding periods = n = 4
Time = t = 5 years

Formula to be used for finding compounding amount:

[tex]A=P (1+ \frac{r}{n} )^{nt} [/tex]

Using the values in the formula, we get:

[tex]A=980 (1+ \frac{0.08}{4} )^{5*4} =1456.23[/tex]

Therefore, the amount compounded over a period of 5 years will be $1456.23

2)
Principal Amount = $980
Compounded Amount = $1456.23
Interest Earned = Compounded Amount - Principal Amount
Interest Earned = 1456.23 - 980 = $ 476.23

Therefore, $476.23 interest will be earned over a period of 5 years.

Which of the following functions is graphed below?!?

Answers

The given graph is for a piecewise function consisting of two intervals:

(1) x ≤ 1 ⇒⇒⇒ the graph in this interval like a cubic function.

(2) x > 1 ⇒⇒⇒ the graph in this interval like a quadratic function

By comparing to the given options

The answer is option c.

Answer:

Option C is correct.

Explanation:

A piece-wise function is a function which is defined by multiple sub-functions, each sub-function applying to a certain interval of the main function's domain.

From the graph we can see that the function is made up of 2 pieces.

Solid dot means- Including

Open-dot means - not- including.

As we can see that the boundary lines are at x=1.

We have to look each line separately to determine each equation:

when [tex]x>1[/tex], it gives the function [tex]y=x^2+4[/tex] and

when [tex]x\leq 1[/tex], it gives the function [tex]y =x^3-2[/tex].

So, the piece-wise function is:

[tex]y=\left \{ {{x^3-2}, x\leq1 \atop {x^2+4}, x>1} \right.[/tex]

An electronics shop offers a small ic chip for $1.50 per unit and $4.00 for large ic chip. on a certain day, 2200 chips were sold and $5050 is collected. how many small ic chips and how many large ic chips were sold?

Answers

Let s and l represent the numbers of small and large ICs sold that day. The problem statement gives rise to two equations.
.. s + l = 2200
.. 1.50s +4.00l = 5050

Solving these by your favorite method gives
.. s = 1500
.. l = 700

1500 small ICs and 700 large ICs were sold.

To determine the number of small and large IC chips sold, we set up a system of linear equations with the given total number of chips (2200) and total earnings ($5050). Solving the system, we found that 1500 small IC chips and 700 large IC chips were sold.

To solve the problem, we can set up a system of linear equations to represent the sales for small and large IC chips. We have two unknowns: the number of small IC chips (let's call it x) and the number of large IC chips (let's call it y). We have two pieces of information to create our equations:

The total number of chips sold is 2200, so x + y = 2200.

The total amount collected is $5050, so 1.50x + 4.00y = 5050.

Solving this system of equations, we multiply the first equation by 1.50 to align it with the second equation:

1.50x + 1.50y = 3300 (Multiply the first equation)

1.50x + 4.00y = 5050 (Second equation)

Subtracting the first new equation from the second gives us:

2.50y = 1750

Dividing both sides by 2.50 to find y gives us y = 700. That means 700 large IC chips were sold. Now, we can substitute y in the first equation to find x:

x + 700 = 2200

x = 2200 - 700

x = 1500

Hence, 1500 small IC chips and 700 large IC chips were sold.

Does anyone know how to prove that OAC and OBC are Congruent.

Answers

Hello,

The first step is to see that sides OA, OC, OB are all equal because they are the radii of the circle. Knowing that those sides are equal means that we have isosceles triangles. That gives us that the base angles are the same.

In OAC, we can subtract 118 from 180 to give us 62 degrees for the 2 bases angles. This would make each angle 31 degrees.

In OBC, the base angles are already 31, leaving the other angle 118.

There we have all the angles the same and 2 sides the same.

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
