Answer:
B. 2x + y = pi + 1.
Step-by-step explanation:
y = sin x + 2 cos x
The slope of a line tangent is the derivative, so:
y' = cos x - 2 sin x
At (pi/2, 1) , substituting for x:-
cos pi/2 - 2 sin pi/2
= 0 - 2 * 1 = -2.
So the slope is - 2 and an equation can be found by using the point-slope formula:
y - y1 = m(x - x1) so:
y - 1 = -2(x - pi/2)
y = -2x + pi + 1
2x + y = pi + 1.
Answer:
correct
Step-by-step explanation:
he is correct because the transformation is a translation and under the translation the image and preimage are congruent.
the measure of the sides are preserved, and the peasure of the angles are preserved so if all the corsponding sides and angles are congruent the hexagons are congruent too
C = 11*(2*d) Try it and see that it fits every sample you have. Again this can be simplified to
C = 22 * d
Answer:
Well I can't make a table but I can explain the answer.
Step-by-step explanation:
So you have $1,800 on a payment plan. In three months, the balance is 1,350. So 1,800-1,350=450. This means he paid $450 in three months. 450/3 is 150. He pays $150 a month. Then 2 months later, (5 months after purchase) he has balance is $1,050. 1,350-1,050=300. 300/2=150. Further evidence of the fact that he pays 150 dollars a month. This means that the 6th month, he will have $900 dollars left on the payment. 7th month... $850, 8th month... $600, 9th month... $450, 10th month... 300 dollars, 11th month... 150, and 12 month he will have paid off all of his computer. Hope it helps, sorry it is so long. Have a great day! :D
Answer:
The irrational number is 4.37124...
Step-by-step explanation:
This is because the number is non-terminating and non-repeating; as in the numbers don't repeat in the same order and they never end.
