SinB=AC/AB=14/50=7/25

Answer: The exact values of indicated trigonometric functions are:

\sin B=\frac{7}{25}\\\\and,\\\\\tan B=\frac{7}{24}

Step-by-step explanation:

Since we have given that

ACB is a right angled triangle,

AC = 14 units

CB = 48 units

BA = 50 units

For sin B ,we will use "SOH" :

\sin B=\frac{AC}{AB}\\\\\sin B=\frac{14}{50}\\\\\sin B=\frac{7}{25}

similarly,

For tan B, we will use "TOH" :

\tan B=\frac{Perpendicular}{Hypotenuse}=\frac{AC}{CB}\\\\\tan B=\frac{14}{48}\\\\\tan B=\frac{7}{24}

Hence, The exact values of indicated trigonometric functions are:

\sin B=\frac{7}{25}\\\\and,\\\\\tan B=\frac{7}{24}

A line goes through the points (-1,9) and (1,1).Write the equation of this line in point slope form using one of these points.
Mashcka [7]

Answer:

y-9= -4(x+1)

Step-by-step explanation:

First, you should know what the format for point slope form is. y-y1=m(x-x1). Now, fill in the points to the x1 and y1 variables. It doesn't matter what ordered pair you use. If the number you fill in is negative, for example, -1, change it to a positive 1. If you're plugging in a positive number such as 9, it becomes -9. Now, it may look like this: y-9=m(x+1). However, you still need to find slope. You can use the expression y-y1/x-x1. 9-1=8. -1-1= -2. So, your slope is 8/-2. However, you can simplify this to -4. Now, plug in -4 to your equation to have your final answer: y-9=-4(x+1).

natka813 [3]

Answer:

Alberta's total overtime pay of the week was $ 145.80.

Step-by-step explanation:

Given that Alberta worked 6 hours at time-and-a-half pay, and 3 hours at double-time pay, and that the value of her regular work hour is $ 9.72, to determine the value of the pay of his overtime, the following equation must be performed:

6x1.5x9.72 + 3x2x9.72 = X

9x9.72 + 6x9.72 = X

87.48 + 58.32 = X

145.8 = X

Therefore, Alberta's total overtime pay of the week was $ 145.80.
