Answer:
r = 1.7 percent
Step-by-step explanation:
I = P(1+r)^nt
assuming the principal is the same
yearly
I = (1 +.07)^1
quarterly
I = (1+ r) ^4t
lets find the quarterly interest rate if we get the same interest
(set the equations equal)
(1 +.07)^1= (1+ r) ^4
simplify
1.07 = (1+r) ^4
take the 4th root on each side
(1.07) ^ (1/4) = (1+r) ^ 4 ^ (1/4)
1.017058525 = 1+r/4
subtract 1
.017058525 = r
multiply by 100
r = 1.7 percent
Domain is the x-values
Range is the y-values
Both listed in order from least to greatest
Answer:
D. 5267
Step-by-step explanation:
In the triangle XY and XZ are tangent to circle C. This means that the length has of XY and XZ are congruent.
So first you have to set the equations to each other to find what b equals to.
85b+83=91b-283
Add 283 to both sides
85b+366=91b
Subtract 85b on both sides
366=6b
Divide by 6
B=61.
Then you substitute 61 as b in the equation for XY.
85b+83
85(61)+83
5185+83
5268
