Answer:
option-D
Step-by-step explanation:
we are given

Let's assume it is equal to 0

We can use quadratic formula
Suppose, we are given quadratic equations as


we can compare and find a,b and c
a=1 , b=2 , c=4
now, we can plug values
and we get

now, we can simplify it
and we get

The amount of rice harvested this year from 690 acres of farmland was 5211570 bushels
<h3>What is an
equation?</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
This year, a large farm harvested rice from 690 acres of farmland. The crop yield was 7,553 bushels per acre.
Hence:
Amount of rice harvested = 7,553 bushels per acre * 690 acres = 5211570 bushels
The amount of rice harvested this year from 690 acres of farmland was 5211570 bushels

Answers:
- slope = 1
- equation is y = x-4
============================================
Explanation:
Two points on this diagonal line are (0,-4) and (1,-3)
Let's apply the slope formula to get the following
m = (y2-y1)/(x2-x1)
m = (-3-(-4))/(1-0)
m = (-3+4)/(1-0)
m = 1/1
m = 1
The slope is 1. We can think of it as 1/1 to indicate "go up 1, and over to the right 1". In other words, slope = rise/run = 1/1.
----------
Note how the graph crosses the y axis at -4, so this is the y intercept.
Since the y intercept is -4, this means b = -4
So with m = 1 and b = -4, we go from y = mx+b to y = 1x+(-4) which simplifies to y = x-4
Answer:
h = 80
Step-by-step explanation:
Remark
The general Volume formula for a pyramid is V = 1/3 * B * h
Givens
base edge = 3 m
V = 240 m^2
Solution
V = 1/3 * B * h
B = s^2
B = base edge^2
B = 3^2
B = 9
240 = 1/3 * 9 * h multiply by 3
240 * 3 = 9 h Divide by 9
80 = h
