Answer:
the equation in letter D is a linear function.
ANSWER
The correct answer is C
EXPLANATION
The given triangle is a right triangle. Since two angles are equal, it is a right isosceles triangle.
This implies that, x=8 units.
Using Pythagoras Theorem,
![{y}^{2} = {8}^{2} + {8}^{2}](https://tex.z-dn.net/?f=%20%7By%7D%5E%7B2%7D%20%20%3D%20%20%7B8%7D%5E%7B2%7D%20%20%2B%20%20%7B8%7D%5E%7B2%7D%20)
This implies that:
![{y}^{2} = 64 + 64](https://tex.z-dn.net/?f=%7By%7D%5E%7B2%7D%20%20%3D%2064%20%20%2B%20%2064)
![{y}^{2} =128](https://tex.z-dn.net/?f=%7By%7D%5E%7B2%7D%20%20%3D128)
Take positive square root,
![{y} = \sqrt{128}](https://tex.z-dn.net/?f=%7By%7D%20%20%3D%20%20%5Csqrt%7B128%7D%20)
![{y} = 8 \sqrt{2}](https://tex.z-dn.net/?f=%7By%7D%20%20%3D%208%20%5Csqrt%7B2%7D%20)
The correct answer is C
It is equal to 3000 to the nearest thousandth
Answer:
c. first quadrant
Step-by-step explanation:
First Quadrant : 0° to 90°
Second Quadrant : 90° to 180°
Third Quadrant : 180° to 270°
Fourth Quadrant : 270° to 360° (or 0°)
If the shape on the red image is scaled to the shape on the blue image, the scale factor is 0.2777.
Explanation:
- The original shape's base in the red image is measured. The base of the red image is measured to be 9 units. Now we measure the same side of the blue image. The base of the blue image is measured to be 2.5 units. So after scaling, the length of the painting will be 2.5 units.
- To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling. In this case, it is the base of both images. So The scale factor =
=
= 0.2777. - So the red image is dilated by a scale factor of 0.2777 to produce the blue image.
