In the equation m-1 1/3=4

romanna [79]

m = 5 $\frac{1}{3}$

note that 1 $\frac{1}{3}$ = $\frac{4}{3}$

isolate m by adding $\frac{4}{3}$ to both sides

m = 4 + $\frac{4}{3}$ = $\frac{16}{3}$ = 5 $\frac{1}{3}$

Find the formula for an exponential function that passes through the two points give.

Ksenya-84 [330]

Answer:

$y=3(2)^{x}$

Step-by-step explanation:

Given.

Two points are given.

$(x, y)=(-1,\frac{3}{2})$ and $(x, y)=(3,24)$

An exponential function is in the general form.

$y=a(b)^{x}$ -------(1)

We know the points $(-1,\frac{3}{2})$ and $(3,24)$

put the first point value in equation 1

$\frac{3}{2}=a(b)^{-1}$

$\frac{3}{2}=\frac{a}{b}$

$a=\frac{3}{2}\times b$ --------(2)

put the second point value in equation 1

$24=a(b)^{3}$ ----------(3)

Put the a value from equation 2 to equation 3

$24=\frac{3}{2}\times b(b)^{3}$

$b^{3+1}=\frac{24\times 2}{3}$

$b^{4} = 16\\b=\sqrt[4]{16} \\b=2$

Put the b value in equation 2

$a=\frac{3}{2}\times 2$

$a=3$

Put the a and b value in equation 1

$y=3(2)^{x}$

So, the exponential function that passes through the points $(-1,\frac{3}{2})$ and $(3,24))$ are $y=3(2)^{x}$ .

STatiana [176]

Answer:

$2561.50

Step-by-step explanation:

If the account earns simple interest, then the balance at the end of 6 months will be ...

... A = P + Prt . . . . . for principal amount P, interest rate r, time period t

... A = $2350 +2350·0.18·6/12 = $2350 + 211.50

... A = $2561.50

Question 3:
If the diver is being pulled up at 25 feet every minute, in 10 minutes they would have been pulled up 10 times that
10*25=250
The diver is now 200 feet below, but 10 minutes ago they would have been 250 feet deeper so:
200+250=450

450 feet
