Answer:

210.65 ft

round as needed

Step-by-step explanation:

Law of Cosines

c^2 = a^2 + b^2 - 2abCosC

c^2 = 125^2 + 210^2 - 2(125)(210)Cos73

c^2 = 15,625 + 44,100 - 15349.5

c^2 = 44,375.5

c = 210.654931107724132

ASAP NEED HELP DESCRIBE AND GET CORRECT a) You are using the equation 4(p – 7) = 44 to determine how many pictures can be saved
ratelena [41]

Answer:

p = 18

Step-by-step explanation:

4(p – 7) = 44

Divide each side by 4, using the division property of equality

4(p – 7)/4 = 44/4

p-7 = 11

Add 7 to each side using the addition property of equality

p-7+7 = 11+7

p = 18

Yet another question.
inna [77]

Answer:

t= 3 years

Step-by-step explanation:

So far we have 2 useful relationshipsP_{t}= P_{o} e^{r*t} and P_{t}=2P_{0}

Now, clearing t

P_{t}= P_{o} e^{r*t} \\\frac{ P_{t}}{P_{o}} = e^{r*t}\\\frac{2 P_{0}}{P_{o}} = e^{r*t}\\2 = e^{r*t}

I apply logarithm

log(2)=r*t\\ t=\frac{log(2)}{r}\\t=\frac{0.3}{0.1} \\ t=3 years

Done
