D.) 16^2 + 63^2 = x^2
The Pythagorean Theorem supports my answer. When given a right angled triangle, the equation a^2+b^2=c^2 should be used to find the missing variable/angle. In this case, when substituting the numbers in the variables, you are left with the correct answer D.
I hope this helped!!
answer: c, the green line
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.
- (2, -7)
- lines r and s and lines t and u must be parallel
which equation can be used to find x, the length of the hypotenuse of the right tr...
