8 0

Answer:

correct value of x = 5

Step-by-step explanation:

\frac{ {( - 2)}^{4x + 2} }{ {( - 2)}^{2x} }  =  {( - 2)}^{12}  \\  =  \frac{ {( - 2)}^{4 \times 5 + 2} }{ { ( - 2)}^{2 \times 5 } }  \\  =  \frac{ {( - 2)}^{22} }{ { ( - 2)}^{10} }  \\  = \frac{4194304}{1024} \\  = 4096 = 4096(i.e \:  {( - 12)}^{12}   = 4096) \\

Find the amount of each payment necessary to amortize the following loan.
Sonbull [250]
Use the formula of the present value of annuity ordinary
The formula is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value 84700
Pmt payment per quarter ?
R interest rate 0.10
K compounded quarterly 4
N time 9 years
We need to solve for pmt
Pmt=pv÷ [(1-(1+r/k)^(-kn))÷(r/k)]
Pmt=84,700÷((1−(1+0.10÷4)^(−4
×9))÷(0.10÷4))=3,595.65

A triangle has sides with lengths of 20 meters, 21 meters, and 29 meters. Is it a right triangle?
coldgirl [10]

Answer:

Yes, the sides form a right triangle.

Step-by-step explanation:

<u>Pythagorean Theorem:</u>

a² + b² = c²

↓

20² + 21² = 29²

║a² = 20² = 400

║b² = 21² = 441

║c² = 29² = 841

↓

400 + 441 = 841

║This equation is true.

↓

Yes, the sides form a right triangle.

Drag each tile to the correct box. Arrange the angles in increasing order of their cosines.
inna [77]

Answer:

\frac{3\pi}{4}

Step-by-step explanation:

we are given different angles

we can see that each angles have different denominators

so, firstly we will find common denominators

denominators are 1 , 2,3,4,6

so, LCD will be 12

now, we will make denominator of all terms 12

\frac{3\pi}{4} =\frac{3\pi\times 3}{4\times 3}=\frac{9\pi}{12}

\pi =\frac{\pi\times 12}{1\times 12}=\frac{12\pi}{12}

\frac{7\pi}{6} =\frac{7\pi\times 2}{6\times 2}=\frac{14\pi}{12}

\frac{5\pi}{3} =\frac{5\pi\times 4}{3\times 4}=\frac{20\pi}{12}

\frac{7\pi}{4} =\frac{7\pi\times 3}{4\times 3}=\frac{21\pi}{12}

\frac{4\pi}{3} =\frac{4\pi\times 4}{3\times 4}=\frac{16\pi}{12}

\frac{3\pi}{2} =\frac{3\pi\times 6}{2\times 6}=\frac{18\pi}{12}

2\pi =\frac{2\pi\times 12}{1\times 12}=\frac{24\pi}{12}

we can see that denominators are same

so, we can arrange it according to numerators as

\frac{9\pi}{12}

we can replace values

and we get order as

\frac{3\pi}{4}
