Answer:
1. the interior angle measure of a parallelogram is 360 degrees
2. diagonal of a parallelogram bisect it into two congruent triangles
3. opposite angles of a parallelograms are congruent
4. a parallelogram has two pairs of parallel sides.
5. consecutive angles of a parallelogram are supplementary
Step-by-step explanation:
Answer:
Only the 2 is negative. The 2nd step is incorrect.
Step-by-step explanation:
In this equation, she did the 2nd step wrong because when you use the factors of 8, -4 and -2 just get you -6, not -2. So, you would have a -4 and a positive 2.
The number of pretzels that must be sold to maximize the profit is 400.
<h3>What is the number of pretzels to be sold in the quadratic equation?</h3>
The number of pretzels to be sold can be determined by taking the derivative of the quadratic equation.
Given that:
P(x) = -4x^2+3200x-100
P'(x) = -8x + 3200
P''(x) = -8
At the critical point;
P'(x) = 0
Thus;
8x = 3200
x = 3200/8
x = 400
P''(400) = -8
P'' (400) < 0
Therefore, at x = 400, P(x) will be maximum.

I = PRT
I = 240
R = 1.6% = 0.016
T = 3
now we sub and solve for P, the money he should deposit
240 = P * 0.016 * 3
240 = 0.048P
240 / 0.048 = P
5000 = P <==== ur answer is 5,000
