Answer:
Linear Equation: y=-44000x+88922000
Year 2009: $526000
By year 2021, they have no more fund
Step-by-step explanation:
Slope formula is difference of y/difference of x. 79000-70200/2003-2005=
-88000/2=-44000.
To find the y intercept, x=0.
It should be year 0. 44000x2003=88132000+790000=88922000
Now put it into y=mx+b
y=-44000x+88922000
Plug in 2009.
It should equal 526000.
Answer:
x^2 -2x + 1
Step-by-step explanation:
Think of a quadratic equation as
ax^2 + bx + c
x^2 -2x +
Comparing the two equations
a = 1 , b = -2, c = ?
c becomes the missing part
Divide b by 2
-2/2 = -1
square the result
-1^2
= 1 this is what to add to get a perfect square
x^2 -2x + 1
(x - 1)^2
Answer:
Yes
Step-by-step explanation:
x is the number of days worked
y is the total amount earned
m is the amount earned per day
so y = mx
Answer:
25.61 feet
Step-by-step explanation:
First, we can draw a picture (see attached picture). With the wall representing the rightmost line, and the ground representing the bottom line, the ladder (the hypotenuse) forms a 80 degree angle with the ground and the wall and ground form a 90 degree angle.
Without solving for other angles, we know one angle and the hypotenuse, and want to find the opposite side of the angle.
One formula that encompasses this is sin(x) = opposite/hypotenuse, with x being 80 degrees and the hypotenuse being 26 feet. We thus have
sin(80°) = opposite / 26 feet
multiply both sides by 26 feet
sin(80°) * 26 feet = opposite
= 25.61 feet as the height of the wall the ladder reaches
