Answer:

y ≈ 32.0°

Step-by-step explanation:

Since the triangle is right use the sine ratio to find y

sin y = $\frac{opposite}{hypotenuse}$ = $\frac{9}{17}$ , thus

y = $sin^{-1}$ ( $\frac{9}{17}$ ) ≈ 32.0° ( nearest tenth )

X - the percent of increase

$210+210x=260 \\
210x=260-210 \\
210x=50 \\
x=\frac{50}{210} \\
x \approx 0.238 \\
x \approx 23.8\%$

The percent of increase is approximately 23.8%.

Answer: 1211.6585 years

Step-by-step explanation:

The equation for exponential growth is: $P=P_oe^{kt}$

P: final population
P₀: initial population
k: rate of decay (or growth)
t: time

Use the half life information to find k:

$\dfrac{1}{2}P_o=P_oe^{k(800)}\\\\\\\dfrac{1}{2}=e^{800k}\qquad \rightarrow \qquad \text{divided both sides by}\ P_o\\\\\\ln\bigg(\dfrac{1}{2}\bigg)=800k\qquad \rightarrow \qquad \text{applied ln to both sides}\\\\\\\dfrac{ln(\frac{1}{2})}{800}=k\qquad \rightarrow \qquad \text{divided both sides by 800}\\\\\\\large\boxed{-0.000867=k}$

Next, input the information (65% decayed = 35% remaining) and the k-value to find your answer.

$.35P_o=P_oe^{-0.000867t}\\\\\\.35=e^{-0.000867t}\\\\\\ln(.35)=-0.000867t\\\\\\\dfrac{ln(.35)}{-0.000867}=t\\\\\\\large\boxed{1211.6585=t}$

F(x)=268 – 22x The value of f(7) 11.86 422 114 -114

vagabundo [1.1K]

Answer:

114

Step-by-step explanation:

To evaluate f(7) substitute x = 7 into f(x), that is

f(7) = 268 - 22(7) = 268 - 154 = 114

Write an equation of a line parallel to y=1/2x+3 that passes through (2,5)

tamaranim1 [39]

$y=\frac{1}{2}x+3 \parallel y=mx+b$

Two lines are parallel when their slopes are the same.
$m=\frac{1}{2} \\ y=\frac{1}{2}x+b \\ \\ (2,5) \\ x=2 \\ y=5 \\ \Downarrow \\
5=\frac{1}{2} \times 2 + b \\ 5=1+b \\ b=4 \\ \\ \boxed{y=\frac{1}{2}x+4}
