Triangle ABC is a right triangle
The length of BC is 5 units.
The area of ABC is ____ square units.
Answer:
50 square units.
Step-by-step explanation:
Given in the picture is a right angled triangle
The coordinates of A are (-9,10) and B are (7,-2) and C is (4,-6)
Given that BC = 5 units
AB = distance between A and B
=distance between two points (-9,10) and (7,-2)
=[tex]\sqrt{(-9-7)^2+(10+2)^2} =\sqrt{256+144} \\=20[/tex]
Thus if we consider BC as base then AB is the height
Area of triangle = 1/2 bh = 1/2 (5)(20)
= 50 square units
The area of the triangle is: 50 square units.
What is the Area of a Triangle?Area of a triangle = 1/2(base × height).
Given right triangle ABC:
Base = BC = 5 units
Height = AB = ?
Using the distance formula, [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex] to find AB:
Let,
A(-9, 10) = (x1, y1)
B(7, -2) = (x2, y2)
Thus:
[tex]AB = \sqrt{(7 -(-9))^2 + (-2 - 10)^2}\\\\AB = 20 $ units[/tex]
Area of triangle = 1/2(5 × 20) = 50 square units.

The dot plot shows how many attempts it took for each student to complete a puzzle:
Is the median or the mean a better measure of center for these data and why?
Mean, because the data are skewed and there are outliers
Mean, because the data are symmetric and there are no outliers
Median, because the data are skewed and there are outliers
Median, because the data are symmetric and there are no outliers
Answer: Mean, because the data are symmetric and there are no outliers.
Step-by-step explanation:
The given dot plot shows how many attempts it took for each student to complete a puzzle.
From the given dot plot, we observe that it has no outlier and the data is symmetric.
Therefore , the mean is a better measure of center for these data because mean the data are symmetric and there are no outliers .
"If a data is skewed or has outliers, then we choose median to measure the center of data over mean."

Which line represents the line of reflection in this diagram?
f
g
h
i
Answer: The correct option is (C) h.
Step-by-step explanation: We are given to select the correct line that represents the line of reflection in the given diagram.
We know that
A line of reflection is a line such that each point of the original figure and the image are equidistant from it.
In other words, we can say that the line of reflection is equidistant from the original figure and the image.
Now, from the figure, we can see that the line g is close on the figure on the left than that in the right. So, line g cannot be the line of reflection.
Line i is close the right figure on the upper half and it is close to the left figure on the lower half. So, line i also cannot be the line of reflection.
Line f cannot be the line of reflection because the shape of the figure is not same in both the sides of f.
The only line that is equidistant from both the figures is line h.
Thus, the line of reflection is line h.
Option (C) is CORRECT.

Kenji wants to divide 48.6 by 0.15. What is the first step that Kenji must complete?
Multiply the divisor and dividend by 10.
Multiply the divisor and dividend by 100.
Divide the divisor and dividend by 100.
Divide the divisor and dividend by 10.
The first step that Kenji must complete is option (B) multiply the divisor and dividend by 100 is the correct answer.
What is a division?A division is a process of splitting a specific amount into equal parts. The number to be divided by another number is called the dividend. The number by which we divide another number (dividend) into equal parts is called the divisor.
For the given situation,
Kenji wants to divide 48.6 by 0.15.
[tex]\frac{48.6}{0.15}[/tex]
Step 1:
To perform division, the first step is to make the divisor and dividend without decimals.
So multiply the divisor and dividend by 100.
⇒ [tex]\frac{48.6}{0.15}=\frac{48.6(100)}{0.15(100)}[/tex]
⇒ [tex]\frac{4860}{15}[/tex]
Hence we can conclude that the first step that Kenji must complete is option (B) multiply the divisor and dividend by 100 is the correct answer.

Using synthetic division, how do you know if a given value is a root of a polynomial function?
Final answer:
A given value is a root of a polynomial function if, after using synthetic division, the remainder is zero. The remainder is found in the last position of the bottom row after performing synthetic division with the given value.
Explanation:
To determine if a given value is a root of a polynomial using synthetic division, follow these steps:
Write down the coefficient of the polynomial.
Place the value you want to test for being a root (let's call it 'c') to the left of the coefficients.
Bring down the leading coefficient to the bottom row.
Multiply 'c' by the value you just brought down and write the result underneath the second coefficient.
Add the second coefficient to the product you just wrote down and write the sum in the bottom row.
Repeat the multiplication and addition process until you reach the end of the row.
If the last number in the bottom row, which represents the remainder, is zero, then 'c' is a root of the polynomial. If the remainder is not zero, 'c' is not a root.
Understanding how to perform such operations is essential, especially when dealing with complex equilibrium problems where square roots, cube roots, or higher roots come into play. If unsure about carrying out these operations, particularly on a calculator, it is advisable to seek assistance from your instructor.
