Perform the indicated operation: (–11⁄2)(–3⁄2).
a. 13⁄4
b. 9⁄4
c. –9⁄4
d. –5⁄2

9/4.

Step-by-step explanation:

(–1 1⁄2)(–3⁄2)

= -3/2 * -3/2

=  9/4.

a and c

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
