Answer:

notice the two angles are vertical to each other making them equal to each other

for the first angle add 45 and 15 together to get 60

set 60 = 4x (the other angle using the vertical angle congruence theorem)

solve for x gives us 15

What is the rate of interest on a loan of $2,000, for 284 days, if the amount of interest is $93.37, using the exact interest me

Viefleur [7K]

Answer: Option (c) is correct. Rate of interest = 6% p.a.

Step-by-step explanation:

Given that,

principal amount = $2000(loan)

time period = 284 days

interest amount (SI) = $93.37

we have to calculate the rate of interest (i),

Simple interest(SI) = principal amount × rate of interest (i) × time period

93.37 = 2000 × i × $\frac{284}{365}$

i = $\frac{34080.05}{568000}$

i = 0.06

i = 6%

What is the graph of the rational function? Y=-3x+5/-5x+2

Natalija [7]

Answer:

See attached picture.

Step-by-step explanation:

Find critical points to graph the rational function.

When x = 0, then y = 5 / 2 = 2.5.

When y=0, then 0=-3x+5 and x= 5/3 =1.6667.

Plot the points (0,2.5) and (1.6667, 0). Then draw the "L" shape graphs of the rational function.
