Answer:

The length of other leg of right angled triangle ABC is 14.4 in

Step-by-step explanation:

Given a right triangle that has 30° angle. The leg adjacent to 30° is 25 inches.

we have to find the length of the other leg.

In ΔABC, by trigonometric ratios

$\tan \theta=\frac{Perpendicular}{Base}$

$\tan 30=\frac{AB}{BC}$

$\frac{1}{\sqrt3}=\frac{AB}{25}$

$AB=\frac{25}{\sqrt3}=14.433\sim 14.4 in$

Hence, the length of other leg of right angled triangle ABC is 14.4 in

Tan(30o)= ?/25
25 * tan(30o) = ?
? = 14.4

Please help me and we should use laws of exponents

Answer:

3.b

$(\frac{8}{3})^{2x+1} *(\frac{8}{3})^{5} =(\frac{8}{3}) ^{x+2}\\\\(\frac{8}{3})^{2x+1 +5} =(\frac{8}{3}) ^{x+2}\\\\\\2x +6 = x+2\\x = -4$

i hope question 3.a. is 5^x ÷ 5^-3 = 5^5

3.a.

$\frac{5^x}{5^{-3}} = 5^5\\\\5^ {x+3} = 5^5\\\\x+3 = 5\\x =2$

working as a waiter, Michael earns $6.50 per hour plus tips. last night he received $36.50 in tips and earned a total of $65.75.

pashok25 [27]

Michael worked 4.5 hours. 65.75 - 36.50 = 29.25, therefore, Michael made $29.25 not including tips. 29.25/6.50 = 4.5

What is the rate of change of the equation y=0.86x+3.302

Alchen [17]

The rate of change of the given equation is: 0.86

Step-by-step explanation:

Rate of change or slope is the steepness of a linear function or line.

When an equation is given in the form of slope-intercept form, the co-efficient of x is the slope or rate of change of the equation.

Given equation is:

$y=0.86x+3.302$

We can see that the co-efficient of x is 0.86

Hence,

The rate of change of the given equation is: 0.86
