Answer:
a = ![\sqrt{7}](https://tex.z-dn.net/?f=%5Csqrt%7B7%7D)
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.:
<em>Suppose ABC is a right triangle with sides a, b, and c and right angle at C. Find the unknown side length using the Pythagorean theorem and then find the values of the six trigonometric functions for angle B. when b=3 and c=4</em>.
My answer:
We will Pythagoras theorem, which states that the sum of squares of two legs of a right triangle is equal to the square of the hypotenuse of right triangle. Because the question says that ABC is a right triangle.
![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
Given that: b=3 and c=4
![a^2+3^2=4^2a^2+9=16a^2+9-9=16-9a^2=7](https://tex.z-dn.net/?f=a%5E2%2B3%5E2%3D4%5E2a%5E2%2B9%3D16a%5E2%2B9-9%3D16-9a%5E2%3D7)
so a =
We know that tangent relates opposite side of a right triangle with adjacent side.
![\text{tan}(B)=\frac{a}{b}\\\text{tan}(B)=\frac{\sqrt{7}}{3}](https://tex.z-dn.net/?f=%5Ctext%7Btan%7D%28B%29%3D%5Cfrac%7Ba%7D%7Bb%7D%5C%5C%5Ctext%7Btan%7D%28B%29%3D%5Cfrac%7B%5Csqrt%7B7%7D%7D%7B3%7D)

The accompanying table shows the number of bacteria present in a certain culture over a 4 hour period, where x is the time, in hours, and y is the number of bacteria.Write an exponential regression equation for this set of data, rounding all coefficients to the nearest thousandth. Using this equation, determine the number of bacteria present after 11 hours, to the nearest whole number.
