Aright triangle has one angle that measures 23 degrees. the adjacent leg measures 27.6 cm and the hypotenuse measures 30cm. what is the approximate area of the triangle?

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
