Answer:
EH = 3.31
Step-by-step explanation:
We have been given a right angle triangle EKL. As KH has been given as the altitude (perpendicular) of the right angled triangle, and K is the right angle, we can say that EK is tthe base of the triangle and EH is the only side lleft, which is the hypotenuse of the triangle.
Where,
EK = Base = 3
KH = perpendicular altitude
EH = Hypotenuse
m<K = 90
m<E = 25
We know that
cosθ = Base/ Hypotenuse
cos 25 = 3/ EH
EH = 3/cos25
EH = 3.31
Perpendicular alitutude can also be calculated by using the formula for tanθ.
Answer:
12.05$
Step-by-step explanation: 2.65$ x 3 - 20$= 12.05$
Part A is C. because it is $3.49 per mango, so it is $3.49m, and $1.40 per papaya, so that is $1.40p, and $1.24 per coconut, so that is $1.24c. You add those up and the expression would be 3.49m + 1.40p + 1.24c.
Part B is B.
Because 3 times 3.49 is 10.47, which is the cost for the mangoes. And 1.4 times 4 is 5.6, which is the cost for the papayas. And 6 times 1.24 is 7.44, which is the cost of the coconuts. Add 10.47, 5.6, and 7.44 and you get 23.51 which is the answer.
He "owled" from the pain xD
For this case, the first thing we must do is define variables.
We have then:
t: number of hours
F (t): total charge
We write the function that models the problem:
Where,
b: represents an initial fee.
We must find the value of b.
For this, we use the following data:
Her total fee for a 4-hour job, for instance, is $ 32.
We have then:
From here, we clear the value of b:
Then, the function that models the problem is:
Answer:
the function's formula is:
