Answer:
A. $2,000
Step-by-step explanation:
<em>Assuming that the money in the savings account will be used to pay off for tractor.</em>
<em>let the number of months be m</em>
Savings after m months will be 500+ 150m
After m months the installments paid will 200m
To find the months it will take to pay for the tractor in m months, savings and the installments will be the price of the tractor. As an equation it be represented as below:
500+150m +200m = 4000
150m + 200m = 4000-500 <em>(grouping like terms)</em>
350m = 3500 <em>(Making m the subject of the formula)</em>
350m/350 = 3500/350
m = 10
Substituting m into the equation of saving after m months
<em>Savings after m months will be</em> 500+ 150m
<em>Savings after m months will be</em> 500 + 150(10)
<em>Savings after m months will be</em> 500 + 1500
Savings after m months will be $2000
Answer and explanation:
The wrong step <u>is changing the sign in step 2</u>
Such that; in step 1 the student had; (x + 6) and (x - 2)
In step 2, the student should have;
x + 6 = 0 and x - 2 = 0 instead of x - 6 = 0 and x + 2 = 0
Step 3, will thus be;
x = -6 and x = 2
The dot product is used to determine the magnitude of the resultant vector of two component vectors. It is expressed as a·b. It does not literally mean that you multiply their values. Instead, you multiply their matrices. However, since we cannot find matrices, let's just find the resultant vector through theorems involving triangles. By cosine law:
R = √[a² + b² - 2abcos(3π/4)]
R = √[60² + 30² - 2*60*30*cos(3π/4)]
R = 83.94
Thus, a·b = 83.94
Answer:
All of the above
Step-by-step explanation:
Any rigid transformation is a similarity transformation. So, too, is (uniform) dilation.
Well 88.5 +88.5+56.2+56.2= 289.4 meters in perimeter
