The correct answer to this question is this one: "D. 11.474"
your calculator probably doesn't do "secant". But sec is 1/cos
so do cos(85) (in degree mode, not radian mode)
then "invert it": 1 / ANS or x^-1 if you have that key
or type
1/cos(85 degrees)= <span>11.4737</span>
Answer:
a = -2
Step-by-step explanation:
(x-2) (x+b) = x² + (b-2) x - 2b = x² + 3x + 5a
b-2 = 3
b = 5
5a = - 2b = - 10
a = -2
Answer:
First Choice
Step-by-step explanation:
The answer is the first choice.
5 divided by 5/3 is 3.
The multiplication to check this quotient is 3 * 5/3 which is what Miko did.
Both the division and the multiplication to check the division are correct.
70 km because 2.5*25 is 65, and 65 + 5 is 70
