Find the area, in square units, of ABC plotted below.
Answer:
43.55
Step-by-step explanation:
1. Use the distance formula on both points AC and AB.
Distance formula is this:
[tex]d=\sqrt{(x2-x1)^2+(y2-y1)^2} \\\\d=\sqrt{(1--5)^2+(8--7)^2} \\\\d=\sqrt{(6)^2+(15)^2} \\\\d=\sqrt{36+225} \\\\d=\sqrt{261} \\\\[/tex]
Distance for AC is 16.16
Now do the same with the numbers for AB and get the distance of 5.39
2. To get the area, use the formula 1/2 x base x height
AB is the base and AC is the height.
1/2 x 16.16 x 5.39 = 43.55
The area of triangle ABC is 43.5 square units.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The shape ABC is a triangle.
Where,
AB = Base
AC = Height
A = (1, 8)
B = (6, 6)
C = (-5, -7)
First, let's find the length of AB using the distance formula:
AB = √((6-1)² + (6-8)²)
= √(25 + 4)
= √(29)
Next, let's find the length of AC using the distance formula:
AC = √((1-(-5))² + (8-(-7))²)
= √(36 + 225)
= √(261)
The area of the triangle ABC can be found using the formula:
Area = (1/2) x base x height
We know that AB is the base and AC is the height,
Area = (1/2) x AB x AC
Area = (1/2) x √(29) x √(261)
Area = (1/2) x √(7569)
Area = (1/2) x 87
Area = 43.5
Therefore,
The area of triangle ABC is 43.5 square units.

he number of homes sold by a realtor during a month has the following probability distribution: Number Sold Probability 0 0.20 1 0.40 2 0.40 What is the expected number of homes sold by the realtor during a month
Answer: 1.2
Step-by-step explanation:
Given the probability distribution :
Number Sold(x) ____0 ______ 1 _______ 2
Probability p(x) ___0.20 ______0.40 ___ 0.40
The expected number of homes sold :
Expected value (E(x)) = Σ (x * p(x))
= (0 * 0.2) + (1 * 0.4) + (2 * 0.4)
= 0 + 0.4 + 0.8

This item is $9000 dollar and it is 90% off how much is the item? Step by step?
Answer:
The item costs $900 after the 90% off.
Step-by-step explanation:
After the 90% off discount, the item costs (100% - 90%) the cost of the original price.
Hence, [tex]\$9000 \cdot (100\% - 90\%)[/tex]
[tex]= \$9000 \cdot 10\%[/tex]

Answer:
C.
Step-by-step explanation:
Choose two points on the line and find the slope. For example, let's use coordinates (0,2) and (5,4).
Use the slope formula to find the slope between these points.
y2-y1/x2-x1
4-2/5-0 = 2/5
Slope of the new line is 2/5.
With the slope, compare the two fractions. Set them up side by side and cross multiply. Whichever one gives you the larger number is the larger fraction. Larger slopes are going to be steeper. So, C is right.
Refer to my picture to see what I mean by cross multiplying.

Answer:
88 degrees
Step-by-step explanation:
This is an isosceles triangle, meaning that the interior angles next to the base will always be the same.
The interior angles of a triangle will always add up to 180 degrees.
So:
46 + 46 = 92
180 - 92 = 88 degrees
Answer:
88 degrees
Explain:
Calculated based on 2 given angles and 1 given side.
∠C = 180° - A - B = 1.53589 rad = 88°
b = a·sin(B)/sin(A) = 1
c = a·sin(C)/sin(A) = 1.38932

Wyatt's office recycled a total of 28 kilograms of paper over 7 weeks. How many weeks will it take Wyatt's office to recycle a total of 32 kilograms of paper? Solve using unit rates.
Answer:
Wyatt's office will take 8 weeks to recycle a total of 32 kilograms of paper.
Step-by-step explanation:
Given that Wyatt's office recycled a total of 28 kilograms of paper over 7 weeks.
So in one week, Wyatt's office will recycle = 28/7 = 4 kilograms / per week
Therefore,
unit rate = 4 kilograms / per weekThus, weeks taken by Wyatt's office to recycle 32 kg of paper
32/4 = 8 weeks
Hence, Wyatt's office will take 8 weeks to recycle a total of 32 kilograms of paper.

which graph represents a function
Answer:
the bottom left one (the graph that looks like a circle) is not a function, but the other ones are.
Step-by-step explanation:
A function is defined so that for every x value within a function has a y value. This means that an x value CANNOT have more than one y value. The bottom right one has two y values for almost every x value within the domain. The top ones are functions, because all x values have only 1 y value (a discontinuous function is still a function!) And the bottom right is too.

Is the point (-18, 31) on the line y = -0.5x + 22?
Answer:
Yes
Step-by-step explanation:
Remember: (x, y)
Substitute the coordinates to the variables (x and y):
Equation: y = -0.5x + 22
Substitution: 31 = -0.5(-18) + 22
31 = 9 + 22?
Correct! The coordinates substituted to its variables solve and make the equation make sense!

5x − 8( 1 + 7x ) = −8
Answer:
x = 0
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
5x - 8(1 + 7x) = -8
Step 2: Solve for x
Distribute -8: 5x - 8 - 56x = -8Combine like terms: -51x - 8 = -8Isolate x term: -51x = 0Isolate x: x = 0Step 3: Check
Plug in x into the original equation to verify it is a solution.
Substitute in x: 5(0) - 8(1 + 7(0)) = -8Multiply: 0 - 8(1 + 0) = -8Add: -8(1) = -8Multiply: -8 = -8Here we see that -8 does indeed equal -8.
∴ x = 0 is a solution of the equation.
