John Blake takes out a mortgage for $80,000. There is a loan of 30 years at $600 per month. This gives a total interest of $136,

yan [13]

Answer: 8.4 %

Step-by-step explanation:

Since, the monthly payment formula,

$P = \frac{r(PV)}{1-(1+r)^{-n}}$

Where, PV is the present value of the loan,

r is the rate per period,

n is the number of periods,

Here, PV = $ 80,000

P = $ 600

n = 12 × 30 = 360

Let r be the annual rate ,

⇒ $600 = \frac{\frac{r}{12}\times 80,000}{1-(1+\frac{r}{12})^{-360}}$

⇒ $600 = \frac{\frac{80000r}{12}}{1-(1+r/12)^{-360}}$

⇒ $600(1-(1+\frac{r}{12})^{-360}) = \frac{80,000r}{12}$

⇒ $r = 0.082$

Thus, the annual rate of interest = 0.082 = 8.2 %

There are 12 boys and 8 girls in a class. If 2 more girls join the class, what is the new ratio for the number of boys to the nu

ycow [4]

Here how it goes, 12 boys to 8 girls is 3:2 in ratio form but since u adding 2 more girls then 8 girls + 2 girls = 10 girls so now its 12 boys + 10 girls so your answer in final would be 6:5.

Which exponential function goes through the points (1, 16) and (4, 128)?

djyliett [7]

Answer:

Here is the complete question (attachment).

The function which represent the given points are $f(x)=8(2)^{x}$

Step-by-step explanation:

We know that a general exponential function is like, $y=a(b)^{x}$

We can find the answer by hit and trial method by plugging the values of $(x,y)$ coordinates.

Here we are going to solve this with the above general formula.

So as the points are $(1,16)$ then for $x=1,\ y=16$

Can be arranged in terms of the general equation.

$ab^1=16$ ...equation(1) and $ab^4=128$ ...equation(2)

$a\times b=16, then\ a=\frac{16}{a}$

Plugging the values in equation 2.

We have

$\frac{16}{b} b^4=128,16\times b^3=128,b=\sqrt[3]{\frac{128}{16}} =\sqrt[3]{8}=2$

Plugging $b=2$ in equation 1.

We have $a=\frac{16}{b} =\frac{16}{2} =8$

Comparing with the general equation of exponential $a=8$ and $b=2$

So the function which depicts the above points = $y=8(2)^x$

From theoption we have B as the correct answer.
