Answer:
{7, 11, 15, 19}
Step-by-step explanation:
The function is defined by the formula y = 2x + 1 ........ (1)
Now, domain of the function are given to be {3, 5, 7, 9}
Hence, from equation (1), at x= 3, y = 2 × 3 + 1 = 7
Now, at x = 5, y = 2 × 5 + 1 = 11
Again, at x = 7, y = 2 × 7 + 1 = 15
Finally, at x = 9, y = 2 × 9 + 1 = 19
Therefore, the range of the corresponding domain of this function is given to be {7, 11, 15, 19}. (Answer)
Answer:
I'm going to do 1 as an example and using what I've taught you, you have to do the rest. Hope my explanation helps.
Step-by-step explanation:
We are given the points (-2, -4) and (-1, -1)
We need to find the slope.
The equation to do so is y2 - y1 / x2 - x1
lest say:
-2 is x1
-4 is y1
-1 is x2
-1 is y2
-1 - (-4) / -1 - (-2)
3/1 = 3
slope (m) = 3
We already know the y-intercept is 2
The equation of a line is y = mx + b
For this problem we just have to substitute what we already know.
y = (slope)x + y-intercept
y = 3x + 2
*TIP*
If the y-intercept is negative, let's say: b = -5 (using slope 8)
the equation will be y = 8x - 5
Hope this helps. I wish you all the best. :)
Answer:

Step-by-step explanation:
Let the side length of the square base =s feet
Let the height of the box = h
Given that the volume of the box = 
Volume of the box =
Then:

Surface Area of a Rectangular Prism =2(lb+bh+lh)
Since we have a square base, l=b=s feet
Therefore:
Surface Area of our closed box
