The vertices of triangle ABC are A(−2, 3), B(4, 3), and C(−2, −4). The triangle is dilated with a scale factor of 2. Estimate the perimeter of the dilated figure to the nearest whole number.
Answer:
Use dynamic geometry software to draw any triangle and label it △ABC. a. Dilate △ABC using a scale factor of 2 and a center of dilation at the origin to form ... the scale factor is k = 3. —. 2 . So, the dilation is an enlargement. b. Because. CP′ ... Graph △ABC with vertices A(2, 1), B(4, 1), and C(4, −1) and its image after a.

After 2014 the sales of new cell phones without cameras began declining. The number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240, where x is the number of years after 2014
Answer:
60,000 people
Step-by-step explanation:
Given the number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240,
x is the number of years after 2014
We can find the number of people that bought the cell phone in 2020. In year 2020, that will be after 6years
Substitute x = 6 into the expression
y=-30x+240
y=-30(6)+240,=
y = -180 + 240
y = 60
Since y is in thousands, hence the the number of people that have bought the cell phone by 2020 is 60,000 people

The area of the Composite figure is 319 sq units.
What is Composite figure?A two-dimensional figure made up of basic two-dimensional shapes such as triangles, rectangles, circles, semicircles, etc
Given that a Composite figure with sides measurements
We will calculate the area by diving the figure in three rectangles
Area of a rectangle = length * width
Therefore, 9*5 + 8*29 + 3*14 = 45 + 232 + 42 = 319 sq units
Hence, The area of the Composite figure is 319 sq units.

How much larger is 6 x 10^5 compared to
2 x 10^3?Explain how you know.
Answer:
6 x 10^5 is 300 times greater than 2 x 10^3.
Step-by-step explanation:
Use division to compare.
(6 × 10^5)/(2 × 10^3) = 6/2 × 10^5/10^3 = 3 × 10^2 = 3 × 100 = 300
6 x 10^5 is 300 times greater than 2 x 10^3.
There is 6 × 10⁵ is 300 times greater than 2 × 10³.
What is the Scientific Notation?Scientific Notation is a way of writing down in the easy form of very large or very small numbers.
The exponents are given in the question, as follows:
6 × 10⁵ and 2 × 10³
The exponents in scientific notation as a shorthand for the number of zeroes in the number.
We use division to compare.
( 6 × 10⁵)/(2 × 10³)
= 6/2 × 10⁵/10³
= 3 × 10²
= 3 × 100
= 300
This means 6 × 10⁵ is 300 times greater than 2 × 10³
