The formula for compound interest, compounded once per year, is:

A = P(1+r)^t, where r is the annual interest rate as a decimal fraction and t is the number of years.

If interest is compounded twice per year, then the above formula is changed to:

A = P(1+r/2)^(2t), where the '2' indicates twice-per-year compounding.

If interest is compounded n times per year, then the above formula is changed to:

A = P(1+r/n)^(nt).

If an equation of the tangent line to the curve y=f(x) at the point where a = 2 is y=4x-5 find f(2) and f'(2)

vichka [17]

hello :
at the point where a=2 y = 4(2)-5 =3 (commun the curve and the tangent)
so :f(2) = 3
f'(2) =4 (slope of the tangent )

Simplify 3(5y + 6) - 4.<br> A. 11y + 14<br> B. 11y + 18<br> C. 15y + 14<br> D. 15y + 2

TiliK225 [7]

3(5y + 6) - 4

First, distribute so that it will make the solving easier.
$(3)(5y) + (3)(6) - 4$
Second, since parentheses indicate multiplication, '3 × 5y = 15y'.
$15y + (3)(6) - 4$
Third, multiply '3 × 6' to get '18'.
$15y + 18 - 4$
Fourth, subtract '18 - 4' to get '14'.
$15y + 14$

Answer: C) 15y + 14

∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+24)^{\circ}∠A=(7x+24) ∘ and m\angle B=(7x-26)^{\circ}∠B=(7x−26) ∘ ,

Arturiano [62]

Answer:

115degrees

Step-by-step explanation:

Given the following angles

m<A=(7x+24)°

m<B=(7x-26)°

Since both angles are supplementary, their sum will be 180 degrees

Taking the sum of the angles

m<A + m<B = 180

7x+24 + 7x - 26 = 180

14x - 2 = 180

14x = 180+2

14x = 182

x = 182/14

x = 13

get m<A

m<A = 7x+24

m<A = 7(13) + 24

m<A = 91 + 24

m<A = 115

Hence the measure of angle m<A is 115degrees
