Triangle ABC has vertices A(0,0), B(3,2), and C(0,4). This triangle may be classified as ?..?
1) equilateral
2) isosceles
3) right
4) scalene
Btw it wasn’t number 2 because that one was inaccurate.
The triange may be classified as (2) isosceles triangle
How to classify the triangle?The vertices are given as:
A(0,0), B(3,2), and C(0,4)
Calculate the side lengths using:
d = √(x2 - x1)^2 +(y2 - y1)^2
So, we have:
AB = √(3 - 0)^2 +(2 - 0)^2
AB = √13
AC = √(0 - 0)^2 +(4 - 0)^2
AC = 4
BC = √(3 - 0)^2 +(2 - 4)^2
BC = √13
Side lengths BC and AB are equal
i.e. AB = BC = √13
Hence, the triange may be classified as (2) isosceles triangle

A cone is cut parallel to its base. Write the best name for the plane section (or cross section).
Final answer:
A cone cut with a plane parallel to its base forms a circular cross section, a concept that is part of the study of conic sections.
Explanation:
When a cone is cut with a plane parallel to its base, the cross section or plane section that is created is a circle. This concept falls under the study of conic sections, which also includes other shapes like ellipse, parabola, and hyperbola, all of which are formed by the intersection of a plane with a cone. If the cut is made closer to the apex, the circle will be smaller, and if it's made closer to the base, the circle will be larger, but all such cross sections remain circular as long as the cut is parallel to the base.

How do you multiply two scientific notation values? Explain the steps you would take to find the product of 6.7 × 106 and 3.2 × 105 written in scientific notation.
Answer is: Calculate the product of the coefficients and powers separately. Apply the product of powers rule to add the exponents. The product is not in scientific notation because the coefficient is greater than 10. Change the coefficient by moving the decimal one place to the left and increasing the exponent by one.
In scientific notation the product is written as [tex](2.144)\times10^{12}[/tex].
Given,Two scientific notation values are [tex]6.7\times10^6[/tex] and [tex]3.2 \times10^5[/tex].
We have to explain the steps to find the product of these values.
Scientific notation:Scientific notation is a widely used floating-point system in which numbers are expressed as products consisting of a number between 1 and 10 multiplied by an appropriate power of 10.
For the product of the above values we multiply coefficients separately like
[tex](6.7\times3.2=21.44)[/tex]
and powers of 10 separately
[tex](10^6\times10^5=10^{11} )[/tex].
So,
[tex]6.7\times10^6 \times 3.2\times10^5=(6.7\times3.2)\times(10^6\times10^5)[/tex].
[tex]6.7\times10^6 \times 3.2\times10^5=(21.44)\times10^{11}[/tex]
Or, in scientific notation form,
[tex]6.7\times10^6 \times 3.2\times10^5=(2.144)\times10^{12}[/tex].
Hence, in scientific notation the product is written as [tex](2.144)\times10^{12}[/tex].

The distance from Boulder City, NV to Santa Fe, NM is around 600 miles. If a map has a scale of 0.3 in for every 30 mi, how far is the scale distance between Boulder City, NV and Santa Fe, NM?
Answer:
6 inches.
Step-by-step explanation:
The distance between two cities is around = 600 miles.
Map has a scale of 0.3 inches = 30 miles.
Therefore, on the scale 1 inches = [tex]\frac{30}{0.3}[/tex] miles
= 100 miles
Since on the map, 100 miles = 1 inches
The distance of 600 miles = [tex]\frac{600}{100}[/tex]
= 6 inches
The scale distance between cities is 6 inches.
Find all real numbers X such that 4x+2>14 AND -21x+1>22
To solve the system of inequalities, we find the values of x that satisfy both conditions: x > 3 and x < -1.
Explanation:To solve this problem, we need to find the values of x that satisfy the given inequalities:
4x+2 > 14
-21x+1 > 22
For the first inequality, subtracting 2 from both sides gives us:
4x > 12
Dividing both sides by 4, we get:
x > 3
For the second inequality, subtracting 1 from both sides gives us:
-21x > 21
Dividing both sides by -21 (and flipping the inequality sign), we get:
x < -1
Therefore, the values of x that satisfy both inequalities are:
x > 3 and x < -1

Caitlyn has a credit card with a spending limit of $1500 and an APR (annual percentage rate) of 18%. During the first month, Caitlyn charged $375 and paid $250 of that in her billing cycle. Which expression will find the amount of interest Caitlyn will be charged after the first month?
The interest that will be charged after the first month is $1.875, calculated by multiplying the remaining balance of $125 by the monthly interest rate of 1.5%.
Explanation:The subject at hand is centered around the concept of credit card interest calculation. In Caitlyn's case, the remaining balance after her payment is $375 - $250 which equals $125. This is the amount that will incur interest.
The APR (annual percentage rate) is 18%, but we must first convert this to a monthly rate by dividing by 12, which equals 0.015 (or 1.5%). The interest charged after the first month is calculated by multiplying the remaining balance by the monthly interest rate. Therefore, the formula to calculate the interest is $125 * 0.015, which equals $1.875.

Find the image of O (0,0) after two reflections, first across L1 and then across L2: L1: y = 2 L2: x = -3
Final answer:
After reflecting the origin (0,0) first across the line y=2, and then across the line x=-3, the final image of the point is at (-6,4).
Explanation:
The reflection of a point in the Cartesian coordinate system can be found using certain rules, depending on the line of reflection.
For the first reflection across L1: y = 2, imagine that every point has to move in a perpendicular motion to this line until it is on the opposite side but the same distance from L1.
The origin (0,0) will move up to (0,4) because it is 2 units away from y=2 and needs to move another 2 units up to be an equal distance on the opposite side of the line.
Next, for the reflection across L2: x = -3, use the same principle, but horizontally.
The point (0,4) is 3 units away from the line x=-3.
Reflecting over this line, you would move (0,4) to the left by 6 units (twice the distance from the line), giving us a final position of (-6,4).
The final position of the point O (0,0) after the two reflections is (-6,4).

Which number line shows the solution to
11x + 14 < –8?
Answer:
D!!
Step-by-step explanation:
Hope it helps!!
The solution to the inequality 11x + 14 < -8 is x < -2. On a number line, this would be a circle at -2 with a line extending to the left.
Explanation:To find the solution to the inequality 11x + 14 < –8, we will first subtract 14 from both sides, which gives us:
11x < -8 - 14
This simplifies to 11x < -22.
Next, we divide both sides by 11 for: x < -2
The solution is x < -2. On a number line, this would be represented by a circle around -2 (not filled in, because the inequality does not include 'equal to') with a line extending to the left (indicating 'less than').

Elliot buys a 5 pound package of ground beef for 12.50 varna buys a package of ground beef for 7.50 at the same unit price. What is the weight of the package
Varna's package weighs 3 pounds, priced at $7.50, matching Elliot's $12.50 package with 5 pounds at same unit price.
To find the weight of Varna's package of ground beef, we can set up a proportion based on the unit price.
Elliot's package:
Price: $12.50
Weight: 5 pounds
Varna's package:
Price: $7.50 (same unit price as Elliot's)
Weight: Let's call it x pounds
We can set up the proportion:
[tex]\[\frac{12.50}{5} = \frac{7.50}{x}\][/tex]
Now, we can cross multiply:
[tex]\[12.50x = 5 \times 7.50\]\[12.50x = 37.50\][/tex]
Now, let's solve for \( x \):
[tex]\[x = \frac{37.50}{12.50}\]\[x = 3\][/tex]
So, the weight of Varna's package of ground beef is 3 pounds.

x = −3.25 and x = 9.25
y = −4.25 and y = 8.25
y = −3.25 and y = 9.25
Answer:
The directrix of the ellipse is:
x= -3.25 and x=9.25
Step-by-step explanation:
As we know that for any ellipse equation of the type:
[tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex] and a>b
The directrix is given by:
[tex]x=h\pm \dfrac{a}{e}[/tex]
where,
[tex]e=\sqrt{1-\dfrac{b^2}{a^2}}[/tex]
Here we have the equation of parabola as:
[tex]\dfrac{(x-3)^2}{5^2}+\dfrac{(y-2)^2}{3^2}}=1[/tex]
Hence, we have:
[tex]h=3,\ k=2,\ a=5,\ b=3\\\\and\\\\e=\sqrt{1-\dfrac{3^2}{5^2}}\\\\e=\sqrt{1-\dfrac{9}{25}}\\\\e=\sqrt{\dfrac{25-9}{25}}\\\\\\e=\sqrt{\dfrac{16}{25}}\\\\e=\dfrac{4}{5}[/tex]
Hence, we have: the directrix as:
[tex]x=3\pm \dfrac{5}{\dfrac{4}{5}}\\\\\\x=3\pm \dfrac{25}{4}\\\\Hence, x=9.25\ and\ x=-3.25[/tex]
Hence, the equation of directrix is:
x= -3.25 and x=9.25
