Given the following functions f(x) and g(x), solve (f + g)(3) and select the correct answer below:
garik1379 [7]
You can evaluate the functions separately, then add results:
.. f(3) = 2*3 +21 = 27
.. g(3) = 3 -24 = -21
(f +g)(3) = f(3) +g(3) = 27 -21 = 6

Or, you can find the combined function and evaluate that for x=3.
.. (f +g)(x) = f(x) +g(x)
.. = (2x +21) +(x -24)
.. = 3x -3
The
.. (f +g)(3) = 3*3 -3 = 6

Either way, the best choice is C) 6.

In ΔBCA, BA = 17 cm, BF = 6 cm, CG = 9 cm. Find the perimeter of ΔBCA.
Rainbow [258]

Answer:

answer is 52 cm

Step-by-step explanation:

BA = 17, BF = 6, and CG = 9

triangle sides BF and BH are congruent because they are tangent lines along the same curve

BH is equal to 6 since BF is equal to 6

this applies to CG and CF and AG and AH

CG is equal to 9

so CF is equal to 9

now we add 6 + 9 for the measurement of side CB

CB = 15

now we do the same for the other two sides

we already know BA = 17 so we subtract it from BH = 6 to find the measurement of AH

AH is equal to 11 and is tangent across the same curve as AG

AG = 11

now we add AG to CG

11 + 9 = 20

now we know  all the side lengths

CB + BA + AC = Perimeter

15 + 17 + 20 = 52

Perimeter of triangle BCA = 52

I don't know why I went through all the trouble if I know no one is going to see this :'(. I just thought the other guy gave the wrong reasons

What would you pay for a $215,000 debenture bond that matures in 15 years and pays $10,750 a year in interest if you wanted to e
velikii [3]

Answer:

at 4% $238,904.53

at 5% $215,000

at 6% $194,118.66

Step-by-step explanation:

Yield is the return received on the investment, The rate of yield is determined by calculating the percentage of return to total investment.

Price of the bond is the present value of all cash flows of the bond. These cash flows include the coupon payment and the maturity payment of the bond.

According to given data

Face value of the bond is $215,000

Coupon payment = C = $10750 annually

Number of periods = n = 15 years

Price of the bond is calculated by following formula:

Price of the Bond = C x [ ( 1 - ( 1 + r )^-n ) / r ] + [ F / ( 1 + r )^n ]

Yield =  4% annually

Price of the Bond = 10,750 x [ ( 1 - ( 1 + 4% )^-15 ) / 4% ] + [ $215,000 / ( 1 + 4% )^15 ] = $238,904.53

Yield =  5% annually

Price of the Bond = 10,750 x [ ( 1 - ( 1 + 5% )^-15 ) / 5% ] + [ $215,000 / ( 1 + 5% )^15 ] = $215,000

Yield =  6% annually

Price of the Bond = 10,750 x [ ( 1 - ( 1 + 6% )^-15 ) / 6% ] + [ $215,000 / ( 1 + 6% )^15 ] = $194,118.66
