Absolute value of -3.25 is 3.25, so you will find it between 2.3 and 3.3 (D)
Answer:
sin A = 3/5
cos A = 4/5
tan A = 3/4
Step-by-step explanation:
Using the trigonometric ratios;
SOH CAH TOA
Sin A = opposite/hypotenuse
cos A = adjacent/hypotenuse
tan A = opposite / adjacent
From the diagram given;
opposite = 3 adjacent =4
We can find the value of the hypotenuse by using the Pythagoras theorem
opposite² + adjacent² = hypotenuse²
3² + 4² =hypotenuse²
9 + 16 =hypotenuse²
25 = hypotenuse²
take the square root of both-side
√25 = √hypotenuse²
5 = hypotenuse
hypotenuse = 5
sin A = opposite / hypotenuse
sin A = 3/5
cos A = adjacent/hypotenuse
cos A = 4/5
Tan A = opposite /adjacent
tan A = 3/4
In this function, x represents the number of 2) HOURS WORKED PER WEEK.
Profit is net of the fixed income of 8600 and variable cost of 22 hourly rate times the number of hours worked by the employee.
Example:
If the employee worked for 100 hours, then the profit would be:
P(x) = 8600 - 22(100)
P(x) = 8600 - 2200
P(x) = 6400
Even if the employee works 24 hours for the whole week or 7 days, they will still earn profit.
24 hours x 7 days = 168 hours
P(x) = 8600 - 22(168)
P(x) = 8600 - 3696
P(x) = 4904
Answer:
y intercept is 3.5 or 3 1/2
Step-by-step explanation:
y=mx+b
substitute the ordered pair (-1,4) in place for y and x in the equation; substitute the slope of -1/4 in place of m to solve for "b"
4= -1/4(-1) +b
4= 2/4+b
subtract 2/4 from both sides
b= 3 2/4 which reduces to 3 1/2 or in decimal form 3.5
Answer:
14 feet
Step-by-step explanation:
The height of the plywood is in two parts, the part that is a side of the right triangle (h - 2) and the 2 feet that is an extension of that side.
One can find (h - 2) with the Pythagorean theorem which states that the sum of the squares of the two legs of the right triangle is equivalent to the square of the hypotenuse. (if the legs were of length a and b and the hypotenuse was of length c, then they could be in the formula 
.
Then this means that you can input the values in the equation so that it appears as: 
. If you solved this equation, you would get that (h - 2) is 12 and when you add 2 to get the total length of h, you would get 14 feet as the total height of the plywood.
Hope that helps : )
