Answer:

-3

Step-by-step explanation:

In the attached image we can see the tan(x/2) relation with sine and cosine

tan(x/2)=sinx/(1+cosx)

sinx=-3/5

and from the triangle we can see that the cosine is equal to -4/5 (this triangle is also called a notable triangle of sides 3,4,5 in lenght)

tan(x/2)=(-3/5)/(1-4/5)

tan(x/2)=-3

Write the exact value solution and an approximation for 10^4x=25

Murrr4er [49]

Answer:

exact value: $x= \frac{log25}{4}$

approximate: x=0.349485

Step-by-step explanation:

Exact Value:

$10^{4x} = 25$

$log (10^{4x})= log 25$

$4x = log 25$

$x= \frac{log25}{4}$

Approximate:

$x= \frac{log25}{4}$

$x=1.39794/4\\$

$x=0.349485$

Last year, 85% of students participated in the school fundraiser. Using this data, what would be the BEST prediction of how many

SpyIntel [72]

Answer:

C. 272

Step-by-step explanation:

Since we know 85% of the students participated last year we can assume the same amount will participate this year so to find the answer you simply do the total number of students (320) multiplied by 85% or .85 to get the best guess of how many students will participate this year.
