Answer:
45 degrees
Step-by-step explanation:
That looks about half a right angle
A right angle is 90 degrees
90/2 = 45
Answer:
20.5 years
Step-by-step explanation:
The population is given by the exponential function ...
p = 16000·(1 +0.022)^t
When p = 25000, we can find the value of t by taking logarithms.
log(25000/16000) = t·log(1.022) . . . . . divide by 16000, take the log
t = log(25/16)/log(1.022) ≈ 20.5 . . . . . . divide by the coefficient of t
It will take about 20.5 years for the population to reach 25000.
The answer is B = 6 3/4. Please mark as brainliest if it did help and have a nice day!
Answer:
√2
Step-by-step explanation:
tan(x) = -1
x = arctan(-1)
x = -π/4
Now since x is between 3π/2 and 2π use use the general form
nπ-π/4
taking n = 2
2×π-π/4
= 7π/4
now tan (7π/4) = -1
so sec (7π/4) = √2

Maddison bought 2 oranges which cost ($.60 x 2 = $1.20) $1.20 total. Ronald bought 4 apples which cost ($.50 x 2 = $2.00). Now if we compare the difference between how much Ronald and Madison have spent so far we see that Ronald has spent $.80 more than Madison ($2.00-$1.20 = $.80). That means that Madison has $.80 more cents to spend on bananas than Ronald. We know that Madison buys 2 more banana than Ronald. So 2 bananas must cost $.80 cents. Divide the 80 cents by the 2 bananas and you figure out that each banana costs $.40 cents. ($.80 / 2 = $.40). To check that this math is correct next add $.40 cents for each banana to the amount of the other fruits they bought. So Madison bought 2 oranges ($1.20) and 3 bananas($.40 x 3 = $1.20) which together costs $2.40 total ($1.20 + $1.20). Ronald bought 4 apples ($2.00) and 1 banana ($.40) which together cost $2.40 ($2.00 + $.40 = $2.40. We can see that if the bananas cost $.40 cents each, Madison and Ronald will end up spending the same amount.
