For questions 1 and 2 , write each expression using a single exponent.

1) \ x^9:x^2=x^7\\
\\
2) \ h^{14}:h^{5}=h^9

<span>For questions 3 and 4, simplify each expression.
</span>
3) \ 4^4:4^6=4^{-2}=\frac{1}{4^2}=\frac{1}{16}\\&#10;\\&#10;4) \ 5^0=1

<span>For questions 6-8, multiply the following polynomial.
</span>
6) \ -2r(8r+5)=-16r^2-10r\\&#10;\\&#10;7) \ 4a(a^2+7a+4)=4a^3+28a^2+16a\\&#10;\\&#10;8) \ (2y-3)(3y-2)=6y^2-4y-9y+6=6y^2-13y+6

Raul uses a credit card to take out a 3-year loan of $4500 at a rate of 15% to purchase
mars1129 [50]

Answer:

Amount of loan pay = $6.840 (Approx.)

Step-by-step explanation:

Given:

Amount of loan borrow = $4,500

Rate of interest = 15% = 0.15

Number of year = 3 year

Find:

Amount of loan pay

Computation:

Future value = Present value[1+r]ⁿ

Amount of loan pay = Amount of loan borrow[1+r]ⁿ

Amount of loan pay = 4,500[1+0.15]³

Amount of loan pay = 4,500[1.15]³

Amount of loan pay = 4,500[1.52]

Amount of loan pay = $6.840 (Approx.)

find the volume of cubical box . if the cost of painting of outer surface is rs 1440 at the rate rs 15 per mcube
bearhunter [10]
Surface of a cubical box=6(side²)

1)We have to calculate the surface of this cubical box.
Rate=cost of painting / surface  ⇒surface=cost of painting/rate

Data:
Rate=$15/m²
cost of painting=$1440

Surface=$1440/($15/m²)=96 m²

2)We find out the length of the side:

Surface of a cubical box=6(side²)

Data:
Surface of a cubical box=96 m2

Therefore:
96m²=6 (side²)
side²=96 m²/6
side²=16 m²
side=√(16 m²)=4 m

3) We find the volume of a cubical box.
volume=(side³)
volume=(4 m)³
volume=64 m³

Answer: the volume of this cubical box would be 64 m³.
