Answer:
2. x = -7/2 and x = 1.
Step-by-step explanation:
2x^2 + 5x - 7 = 0
(2x + 7)(x - 1) = 0
x = -7/2, 1.
Answer: 1 Brutus Bites= $9.25
1 Lucky Licks= $8.00
Step-by-step explanation:
2B + 3L= 42.50
5B + 6L= 94.25
Using the elimination method multiply the first equation by -2 to cancel the L's out.
5B + 6L= 94.25
-4B - 6L= -85
B= 9.25
Then put this number back into the equation to solve the other.
2B + 3L = 42.5
5B + 6L = 94.25
2(9.25) + 3(8) = 42.5
5(9.25) + 6(8) = 94.25
Substitute sin(x) = tan(t) and cos(x) dx = sec²(t) dt. We want this change of variable to be reversible, so let's assume bot x and t are bounded between 0 and π/2.
Then we have

Recall the Pythagorean identity,
1 + tan²(t) = sec²(t)
Then
√(1 + tan²(t)) = √(sec²(t)) = sec(t)
and the integral reduces to

Change the variable back to x, so the antiderivative is
