Step-by-step explanation:
(1 - cos²A) (1 + tan²A) = tan²A
(sin²A)(sec²A) = tan²A
(sin²A)(1/cos²A) = tan²A
(sin²A)/(cos²A) = tan²A
tan²A = tan²A → <u>Proved</u>
Answer:
5400 + 351 = 5751
Step-by-step explanation:
The rates are equivalent because both of them do 30 jumping jacks a minute.
Answer:
<u>D. 0.92t, is indeed a correct answer, but probably B or E are not correctly written. The second correct way is t - 0.08t.</u>
Step-by-step explanation:
If the farmer recently sold 8% of the original acreage of his plot and t is the original acreage, therefore:
8% = 0.08
Thence, the expressions to describe two ways to find the new acreage are:
t - 0.08t
t - 0.08t = 0.92t
<u>D. 0.92t, is indeed a correct answer, but probably B or E are not correctly written. The second correct way is t - 0.08t.</u>
