Area of original poster=80
Area of enlarged poster=320
The area of the enlarged is 4x larger than the original
I think this is how you would do it but good luck
Answer:
Step-by-step explanation:
The given box in both questions are cuboid.
Question 3:
Volume of cuboid = length * width * height
= 3 * 3 * 5 = <u>45 units.</u>
Question 4:
Volume of cuboid = length * width * height
= 4 * 2 * 6 = <u>48 units</u>
y = mx + b, where m = slope, and b = y-intercept.
y = 3x + 3
y = 1/2x - 3
y = 1/2x + 3
y = 3x + 1/2
we can eliminate 2 and 4 since the y-intercept in the graph is shown as (0, 3)
This leaves us with
y = 3x + 3 and y = 1/2x+3
m = change in y / change in x
We take any two points on the line to find the slope.
I chose (2, 4), (0, 3)
change in x: 2 - 0 = 2
change in y: 4 - 3 = 1
m = 1/2
This leaves us with the only answer that has the slope of 1/2 and the y-intercept of 3.
option: 3
y = 1/2x + 3
Answer:
<em>Standard line equation</em><em>:</em><em> </em>
y=ax+b
The point (5,1) is on the line. so :
1=a(5)+b → 1=5a+b
The point (1,-5) is also on the line. Then :
-5=a(1)+b → -5=a+b
Subtract the two equations in terms of a and b. we have:
6=4a → a=3/2 , b=-6.5
<em>y=1.5x-6.5</em>
Answer:
114.89 degrees
245.11 degrees
Step-by-step explanation:
cos is negative in the second and third quadrant ("pointing" on the x-axis to the left).
so, the first answer for the second quadrant is
114.89 degrees.
the answer for the third quadrant is then backwards the same angles from a full 360 degree rotation
360 - 114.89 = 245.11 degrees
