4 times 5 is 20. So we’d multiply 7 by 5 to get 35 pints of blue paint.

Answer:

35 pints

Step-by-step explanation:7 divided by 4 is 1.75 so thats how much 1 is so then you do 1.75 times 20 and you get 35

Find the range of the graphed function.
rusak2 [61]

Range is set of all y-values. To find a range of graphed function, we need to know that range starts from the minimum value of graph to maximum value. That's because the minimum value is the least value that you can get by substituting the domain and the maximum value is the largest value that you can get by substituting the domain as well.

Now we don't talk about domain here, we talk about range. See the attachment! You are supposed to focus on y-axis, plane or vertical line. See how the minimum value of function is the negative value while the maximum value is positive.

That means any ranges that don't contain the negative values are cleared out. (Hence A and C choices are wrong.)

Next, range being set of all real numbers mean that graphed functions don't have maximum value or minimum value (We can say that both max and min are infinite.)

Take a look at line graph as an example of range being set of all real numbers, or cubic function.

Answer/Conclusion

  • The range exists from negative value which is -9 to the maximum value which is 5.
  • That means the range is -9<=y<=5

A diver jumps up and over from a cliff in order to avoid rocks and land in the deeper water. The path of the dive can be modeled
lions [1.4K]

Answer:

48.06  to the nearest hundredth.

Step-by-step explanation:

f(x) = -16x^2 + 2x + 48

To find the maximum height we convert to vertex form:

= -16(x^2 + 1/8x) + 48

= -16[x + 1/16)^2 - 1/256] + 48

= -16(x + 1.16)^2  + 16/256 + 48

= 48.0625.

If A = (-2, -4) and B = (-8, 4), what is the length of AB?
svetoff [14.1K]

Answer: OPTION D

Step-by-step explanation:

To solve this exercise you must use the formula for calculate the distance  between two points, which is shown below:

d_{(A,B)}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Now, you must substitute the points given in the problem into the formula:

A(-2,-4)

B(-8,4)

d_{(A,B)}=\sqrt{(-8-(-2))^2+(4-(-4))^2}

Then, the result is:

d_{(A,B)}=10units
