Answer:

\$5,828.28

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=5\ years\\ P=\$4,900\\ r=0.035\\n=2  

substitute in the formula above  

A=\$4,900(1+\frac{0.035}{2})^{2*5}  

A=\$4,900(1.0175)^{10}=\$5,828.28

7<br> Write an equation of a line<br> with slope of 23 and<br> y-intercept -6.
emmainna [20.7K]

Answer:

y = 23x - 6

Step-by-step explanation:

The formula for line is y =  mx + b

m is the slope, so plug in 23

b is the y intercept, so plug in -6

So it would be y = 23x + (-6), which simpify into y = 23x - 6

Pls, help!!!! Will make brainliest!!!
riadik2000 [5.3K]

Answer:

y=2x+6

Step-by-step explanation:

slope intercept formula → y=mx+b

\frac{6-2}{0-(-2)} =\frac{4}{2} =2\\

so 2 is your slope and the point (0,6) crosses the y-intercept at 6 since x = 0

plugin 2 for m (or the slope) and 6 for b (y-intercept)

your answer → y=2x+6

If you place a cup of 210 degree Fahrenheit coffee on a table in a room that is 68 degrees fareinheit, and ten minutes later, it
Lana71 [14]
Newton's Law of Cooling

Tf=Ts+(Ti-Ts)e^(-kt)   where Tf is temp at time t, Ts is temp of surroundings, Ti is temp of object/fluid.  So we need to find k first.

200=68+(210-68)e^(-10k)

132=142e^(-10k)

132/142=e^(-10k)

ln(132/142)=-10k

k=-ln(132/142)/10

k≈0.0073  so 

T(t)=68+142e^(-0.0073t)  so how long until it reaches 180°?

180=68+142e^(-0.0073t)

112=142e^(-0.0073t)

112/142=e^(-0.0073t)

ln(112/142)=-0.0073t

t= -ln(112/142)/(0.0073)

t≈32.51 minutes
