Answer:
it would be 500
Step-by-step explanation:
since blue is covering 50% of the circle than the probability of it landing on blue is 50% and 50% of 1000 is 500
We don't know whether those two sides are both legs
of the right triangle, or if BC is the hypotenuse.
If AC and BC are both legs, then
AB = √ (AC² + BC²)
= √ (7² + 8²)
= √ (49 + 64) = √ 113 .
If BC is the hypotenuse of the right triangle, then
AB = √ (BC² - AC²)
= √ (8² - 7²)
= √ (64 - 49) = √ 15 .
Answer:
After 2.80 years the price drops to 300 $
Step-by-step explanation:
Ryan bought a new computer for $2,100.
Price of computer = 2100 $
The value of the computer decreases by 50% each year.
Let p(n) be the price of computer after n years.
Now we need to find n when price is 300 $.
0.50ⁿ x 2100 = 300
0.50ⁿ = 0.143
n log (0.5) = log 0.143
n x -0.301 = -0.845
n = 2.80
After 2.80 years the price drops to 300 $
To find Angle A we use cosine
cos ∅ = adjacent / hypotenuse
From the question
The adjacent is 17
The hypotenuse is 38
So we have
cos A = 17/38
A = cos-¹ 17/38
A = 63.4
<h3>A = 63° to the nearest degree</h3>
To find Angle C we use sine
sin ∅ = opposite / hypotenuse
From the question
The opposite is 17
The hypotenuse is 38
So we have
sin C = 17/38
C = sin-¹ 17/38
C = 26.57
<h3>C = 27° to the nearest degree</h3>
Hope this helps you
