Answer:
#1 -2800, 10000
#2 -2800
Step-by-step explanation:
you simply just have to find the average around both mid points, and y equals up and down, so they want t know the average of the height
All these equations are in the form of ax^2 + bx + c = 0, where a, b, and c are some numbers. the discriminants of equations like this are equal to b^2 - 4ac. if the discriminant is negative, there are two imaginary solutions. if the discriminant is positive, there are two real solutions. if the discriminant is 0, there is one real solution.
<span>x^2 + 4x + 5 = 0
</span>b^2 - 4ac
4^2 - 4(1)(5)
16-20
-4, two imaginary solutions.
<span>x^2 - 4x - 5 = 0
</span>b^2 - 4ac
(-4)^2 - 4(1)(-5)
16 + 20
36, two real solutions.
<span>4x^2 + 20x + 25 = 0
</span>b^2 - 4ac
20^2 - 4(4)(25)
400 - 400
0, one real solution.
Answer:
1)
23265
2)
9478.125
3) 102369.09375
Formula nonsense: V=l*w*h
1) meaning V= 33*47*15 so V= 23265
2) meaning V= 22.5*33.7*12.5 so V= 9478.125
3) meaning V= 122.25*50.75*16.5 so V= 102369.09375
<h2>Step-by-step explanation:</h2>
-5/7 + x = -1
(-5+7x)/7 = -1
-5 + 7x = -7
7x = -2
<h2>x = -2/7</h2>
please change the digit as per ur QUESTION
