Answer:
1
Step-by-step explanation:
Using the trigonometric identities
tan(90 - x) = cotx , cotx = 
Given
tan1tan2tan3....................... tan87tan88tan89
= tan1tan2tan3............... tan(90-3)tan(90-2)(tan90 - 1)
= tan1tan2tan3.............. cot3cot2cot1
= tan1cot1tan2cot2tan3cot3 ........................
= 1 × 1 × 1 ×....................... × 1
= 1
Answer:
<em>* Siobhan's profit at the grocery store ⇒ $ 10.8 *</em>
Step-by-step explanation:
See below;
Priya's 40% profit in the grocery store ⇒ 40/100 * 9 = 2/5 * 9 = 18/5 ⇒ $ 3.6,
Priya's profit at the grocery store ⇒ 9 + 3.6 ⇒ $ 12.6,
Siobhan's 15% of Priya's profit from the store ⇒ 15/100 * 12.6 = $ 1.8
Siobhan's profit at the grocery store ⇒ 12.6 - 1.8 = $ 10.8
<em>* Siobhan's profit at the grocery store ⇒ $ 10.8 *</em>
Answer:
4/5
Step-by-step explanation:
SImply use slope formula. We see the graph has defined points at (5, 4), and (-5, -4).
m=(Y2-Y1)/(X2-X1)
(4-(-4))/(5-(-5))=8/10
Simplify 8/10
=4/5
