Tahmar knows the formula for simple interest is I = Prt, where I represents the simple interest on an amount of money, P, for t
frez [133]
The formula to find the simple interest earned is
I = Prt
Solve for p by dividing both sides by rt to get
P=I/rt
P=?
I=20
R=0.05
T=5years
So
P=20÷(0.05×5)
P=80

What is the area of this composite figure<br> 48.56cm2 <br> 49.12cm2<br> 74.24cm2 <br> 36.56cm2
Vlada [557]

Answer:

D. 36.56 cm²

Step-by-step explanation:

The composite figure is composed of a rectangle and two semicircles.

The two semicircles makes 1 full circle.

Thus:

Area of the composite figure = area of rectangle + area of circle

= L*W + πr²

L = 6 cm

W = 4 cm

r = ½(4) = 2 cm

Area = 6*4 + π*2²

Area = 24 + 12.56

Area = 36.56 cm²

Thea's monthly rent is 1,600 dollars. If the rent goes up 3% a year, then the rent will be
3241004551 [841]

Factor the polynomial function over the complex numbers?? <br><br><br><br> F(x)= x^4 -x^3-2x-4
pav-90 [236]

Answer: The factor form of the function F(x) is (x+1)(x-2)(x^2+2), where  (x^2+2) gives two complex roots.

Explanation:

The given function is,

F(x)=x^4-x^3-2x-4

According to the rational root theorem 1 and -1 are the possible roots of each polynomial.

Put x=-1

F(-1)=(-1)^4-(-1)^3-2(-1)-4=0

Since the value of F(x) is 0 at x=-1 therefore the -1 is a root of given polynomial and (x+1) is a factor of F(x).

Use synthetic division method to divide the polynomial by (x+1).

The last row of the synthetic division shows the coefficient of remaining polynomial.

F(x)=x^4-x^3-2x-4=(x+1)(x^3-2x^2+2x-4)

At x=2 the value of F(x) is 0, therefore (x-2) is a factor of F(x).

Use synthetic division method to divide the polynomial by (x-2).

F(x)=(x+1)(x-2)(x^2+2)

Therefore the roots of F(x) are,

-1,2,\pm i\sqrt{2}

F(x)=(x+1)(x-2)(x+i\sqrt{2})(x-i \sqrt{2} )

Where (x+1)(x-2) factors with real root and (x+i\sqrt{2})(x-i \sqrt{2} ) are factors with complex roots.
