Answer:

5859375

Step-by-step explanation:

These are the terms of a geometric sequence with n th term

$a_{n}$ = $a_{1}$ $r^{n-1}$

where r is the common ratio and $a_{1}$ the first term

here r = $\frac{375}{75}$ = $\frac{75}{15}$ = $\frac{15}{3}$ = 5 and $a_{1}$ = 3, hence

$a_{10}$ = 3 × $(5)^{9}$ = 5859375

Do 0.3 and 3.0 have the same value. Explain.<br><br> Explain=10 points

just olya [345]

<span>No, 0.3 and 3.0 do not have the same value. The zero in front the decimal point, means that the next digit has a value less than one. The first decimal position is greater than the second decimal position, and it is greater than the fhird decimal positio, and so on; 0.3 is 3/10. The digit 3 in 3.0 has value of 3 units which is greater than 3/10.</span>

SCALCET8 3.9.017.MI. Two cars start moving from the same point. One travels south at 48 mi/h and the other travels west at 20 mi

Veronika [31]

Answer:

The rate at which the distance between the cars increasing two hours later=52mi/h

Step-by-step explanation:

Let

Speed of one car, x'=48 mi/h

Speed of other car, y'=20 mi/h

We have to find the rate at which the distance between the cars increasing two hours later.

After 2 hours,

Distance traveled by one car

$x=48\times 2=96 mi$

Using the formula

$Distance=Time\times speed$

Distance traveled by other car

$y=20\times 2=40 mi$

Let z be the distance between two cars after 2 hours later

$z=\sqrt{x^2+y^2}$

Substitute the values

$z=\sqrt{(96)^2+(40)^2}$

z=104 mi

Now,

$z^2=x^2+y^2$

Differentiate w.r.t t

$2z\frac{dz}{dt}=2x\frac{dx}{dt}+2y\frac{dy}{dt}$

$z\frac{dz}{dt}=x\frac{dx}{dt}+y\frac{dy}{dt}$

Substitute the values

$104\frac{dz}{dt}=96\times 48+40\times 20$

$\frac{dz}{dt}=\frac{96\times 48+40\times 20}{104}$

$\frac{dz}{dt}=52mi/h$

Hence, the rate at which the distance between the cars increasing two hours later=52mi/h

A video game club charges a fixed annual membership fee of $18 and $3 per video game rented. Let f(n) represent the total annual

user100 [1]

Since there is a flat membership fee of $18, the y intercept is 18. And since there is a $3 fee per number of video games rented, n, the slope or rate of change of the linear equation is 3. The slope-intercept form of a line is:

f(x)=mx+b, where m=slope and b=y-intercept so in terms of n, games rented, the cost, f(n) is:

f(n)=3n+18
