If you would like to simplify <span>4 + (-3) - 2 * (-6), you can do this using the following steps:
</span><span>4 + (-3) - 2 * (-6) = 4 - 3 + 2 * 6 = 1 + 12 = 13
</span>
The correct result would be 13.
Answer:
Below.
Step-by-step explanation:
When you graph this you'll see that it is a rhombus, which has 4 equal sides and the 4 angles are not 90 degrees.
You could draw a square on the coordinate plane using A(0.0). B (0,3), C(3,3) and D(3,0). The sides of the square are all equal to the sides of the rhombus but the 2 quadrilaterals are not congruent because the angles have different values,
Step-by-step explanation:
For them to owe you a total of$2000 then an interest of $2000-320=$1680 must have accrued over the time <em>T</em>
<em>T</em><em>=</em><em>$</em><em>1</em><em>6</em><em>8</em><em>0</em><em>×</em><em>1</em><em>0</em><em>0</em><em>/</em><em>3</em><em>2</em><em>0</em><em>×</em><em>1</em><em>1</em>
<em>T</em><em>=</em><em>4</em><em>7</em><em>.</em><em>7</em><em>2</em><em>7</em><em>2</em><em>.</em><em>.</em><em>.</em><em>≈</em><em>4</em><em>7</em><em>.</em><em>7</em><em>3</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>nearest</em><em> </em><em>hundredth</em>
Proof,
Interest after 47.7262...years which is converted to 525/11 years
=($320×11×525/11)/100
=$1680
therefore total amount which will be owed at that time =principal+interest accrued
=$320+1680=$2000
Answer:
C(x) = 8*x + 8* (1000)/x + 80
C(x) Domain x > 0
Step-by-step explanation:
enclosed area 1000 ft²
let x be side perpendicular to the river
and y parallel to the river
Then:
A = x*y y = A / x y = 1000/x
Cost of one side (x) 4*x $ then two sides cost = 4*2*x cost = 8*x
Cost of one side (y) 8*y $ 8* (1000/x)
Cost of four cornes posts 4*20 = 80 $
Total cost C(x)
C(x) = 8*x + 8* (1000)/x + 80
R { x > 0}
Taking derivatives both sides of the equation
C´(x) = 8 - 8000/x² C´(x) = 0 8 - 8000/x² = 0
8x² -8000 = 0 x² = 1000
x = 100
It is 10%. i hope this is useful
