Answer:
Parallel cut-rectangle
Perpendicular cut-triangle
Step-by-step explanation:
A rectangular pyramid has a base that is a rectangle, but comes up into a point.
18 - (-f) = 91
Subtracting a negative value changes to addition:
18 + f = 91
Subtract 18 from both sides:
F = 73
Answer:
15
Step-by-step explanation:
please give me brailiest
To calculate the slope containing two points, we can use that formula:
"m" represents the slope and coordinates are expressed as follows: (x, y)
Let's go to the calculations.
The answer is 2 uc.

Let's analyze Hannah's work, step-by-step, to see if she made any mistakes. </span>In Step 1, Hannah wrote

<span> as the sum of two separate derivatives </span>

<span>using the </span><span>sum rule.
</span>
This step is perfectly fine. In Step 2,

was kept as it is, and

was rewritten as

using the constant rule.Indeed, according to the constant rule, the derivative of a constant number is equal to zero.
This step is perfectly fine. In Step 3,

was rewritten as

supposedly using the constant multiple rule.
The problem is that according to the constant multiple rule,

should be rewritten as

and not as

.

Therefore, Hannah made a mistake in this step.</span>
