If you're using a graphing calculator, make sure you're in DEG mode (not RAD). There probably is no button for the secant function, but remember that secant is defined as the reciprocal of cosine:
So on your calculator, you'd type
1/cos(19)
and you should get about 1.0576.
Answer:
110 in²
Step-by-step explanation:
The area of a trapezoid is given by the formula ...
A = (1/2)(b1 +b2)h . . . . . . where b1 and b2 are the lengths of the parallel bases, and h is the perpendicular distance between them.
In your problem, b1 and b2 are 13 in and 9 in, and h is 10 in. Putting these values into the formula, we find the area to be ...
A = (1/2)(13 in + 9 in)(10 in) = 110 in²
The area of the trapezoid is 110 square inches.
_____
First, we identify the appropriate formula to use for the geometry shown in the diagram.
Next, we determine from the diagram the values to use in the formula.
Last, we evaluate the formula and make a summary statement of results.
It would be 3 because .50 and up is one up and .49 and down is is one down
Given:
8000 homes
color flyers : $0.08 each
black and white flyers : $0.05 each
budget of $500
c + b = 8,000
0.08c + 0.05b = 500
c = 8,000 - b
0.08(8,000 - b) + 0.05b = 500
640 - 0.08b + 0.05b = 500
-0.03b = 500 - 640
-0.03b = -140
b = -140 / -0.03
b = 4,667 black and white flyers
c = 8,000 - b
c = 8,000 - 4,667
c = 3,333 colored flyers
0.08(c) + 0.05(b) = 500
0.08(3,333) + 0.05(4,667) = 500
266.64 + 233.35 = 500
499.99 = 500
500 = 500
