Answer:

Y = 9

Step-by-step explanation:

2Y (with Y having a value of 9) would be equal to 2 x 9 which would give you 18

then you take the 18 and subtract 10x

which would give you 8x with the x not being relevant in your case (maybe)

A certain forest covers an area of 4600km. Suppose that each year this area decreases by 7.75%. What will the area be after 13 y

wolverine [178]

Answer:

$1679.60\ km^2$

Step-by-step explanation:

-We can use the exponential decay function to estimate the size after 13 years:

$P_t=P_oe^{-rt}$

Where:

$P_t$ is the size after t years, t is the time, r is the rate of decay and $P_o$ the original size.

#We substitute and calculate as:

$P_t=P_oe^{-rt}\\\\=4600e^{-13\times 0.0775}\\\\=1679.60$

Hence, the forest covers $1679.60\ km^2$ after 13 years.

26. Julie says that sin A/cos A = tan A and sin B / cos B = tan B. Use the triangle shown to prove

PSYCHO15rus [73]

Julie is correct because:

$\frac{\sin A}{\tan A}=\frac{a/c}{b/c}=a/b=\tan A \\ \\ \frac{\sin B}{\cos B}=\frac{b/c}{a/c}=b/a =\tan B$
