Maxwell purchased $15,000 worth of 52-week T-Bills for $14,650. What will be the rate of return on his investment?
Ket [755]

Answer:

2.39%

Step-by-step explanation:

Maxwell bought $15,000 worth of 52-week T-bills for $14,650

Therefore the rate of return on investment can be calculated as follows

= 15,000-14,650/14,650× 100

= 350/14,650 × 100

= 0.02389 × 100

= 2.39%

Hence the rate of return on this investment is 2.39%

For the function f(x)=-6X^2+3X +7 Evaluate f(-1)
Zigmanuir [339]

Answer:

f( - 1) =  - 2

Step-by-step explanation:

f(x) =  - 6 {x}^{2}  + 3x + 7 \\ f( - 1) =  - 6 {( - 1)}^{2}  + 3( - 1) + 7 \\  =  - 6(1) + ( - 3) + 7 \\  =  - 6 - 3 + 7 \\  =  - 2

I hope I helped you^_^

If the midpoint between (x, 3) and (9, 9) is (7, 6), find the value of x.
crimeas [40]

The midpoint formula states that the midpoint is equal to (x1 + x2/2, y1 + y2/2). However, in this instance, we only have to deal with the x-values because that is where our unknown variable x is. Using our formula for the x-values, we can set up the following equation:

(x + 9)/2 = 7

To solve this equation, we must first multiply both sides by 2 to get rid of the denominator on the left side of the equation.

x + 9 = 14

Next, we should subtract 9 from both sides of the equation to get the variable x alone on the left side.

x = 5

Therefore, your answer is x=5.

Hope this helps!

Answer:

The explicit formula for f(n) is:

f(n) = -71 \cdot 4.2^{n-1}

Step-by-step explanation:

The explicit formula is described by the following geometrical progression:

f(n) = -71 \cdot 4.2^{n-1}
