Answer:

tan a + cot b

Step-by-step explanation:

It's already simplified.

There are alternate forms like

$sec(a)csc(b)cos(a-b)\\\\sec(a)csc(b)[sin(a)sin(b)+cos(a)cos(b)]\\\\\frac{sin (a)}{cos (a)} +\frac{cos(b)}{sin(b)}$

# 15. Q. Find the area of the trapezoid

harina [27]

Answer:
219.96 yd²

Explanation:
The area of the trapezoid can be calculated using the following rule:
Area of trapezoid = $\frac{b1 + b2}{2} * h$
where:
b1 is the length of the first base
b2 is the length of the second base
h is the height

Now, in the given we have:
b1 = 15.8 yd
b2 = 21.8 yd
h = 11.7 yd

Substitute with the givens in the above equation to get the area as follows:
area = $\frac{15.8 + 21.8}{2} * 11.7 = 219.96 yd^2$

Hope this helps :)

The amount of fuel in a tractor's fuel tank is changing according to the equation y=−3x+40 , where x = time in hours and y = amo

Alenkasestr [34]

Answer:

The rate of change is "-3". Which means the rate at which the tractor uses fuel.

Step-by-step explanation:

The equation describes a line and any line follows the equation:

y = m*x + c

Where "m" is the rate of change and "c" is the shift on the line. Comparing the equation for the fuel and the equation from the line, the rate of change must be "-3". The rate of change in this context describes the speed at which the tractor uses fuel, at a rate of 3 gallons per hour.

What is “ f(x) = 2x^2- 32x” in standard form if it has one?

kap26 [50]

Most textbooks interpret standard form of a quadratic function to be as follows:

f(x) = $a x^{2} + bx + c$

In the function f(x) = $2 x^{2} - 32x$ , notice we do not have a value for "c". Just place a "0" in for the c and you have standard form.

the criteria for standard form:
1. All like terms are combined
2. Degree must drop from left to right
3. The leading coefficient cannot be equal to zero.
