Answer
Law of Sines
Step-by-step explanation:
If you have all three side lengths, you can use law of sines.
side length a/sin of angle a=side length b/sin of angle b=side length c/sin of angle c
not sure if that makes sense but look up the law of sines!
25% means 1/4
divide 268 with 4 and the answer is
67
Answer:
the 4 one maybe
Step-by-step explanation:
The exponential function is :
y=ab^x
We have two points:
(1, 7.5)
(3, 16.875)
First point:
(1 , 7.5)
x=1
y=7.5
y=ab^x
7.5=ab¹
Second point:
(3 , 16.875)
x=3
y=16.875
y=ab^x
16.875=ab³
Then, always is true that.
7.5 / 16.875 = (ab) / (ab³)
7.5(ab³)=16.875(ab)
7.5ab³ / a
b²=16.875
7.5b²=16.875
b=⁺₋√(16.875 / 7.5)
b=⁺₋1.5
if b=-1.5 ⇒ 7.5=a(-1.5) ⇒a=-5
y=-5*(-1.5)^x
y=5(1.5^x)
if b=1.5 ⇒ 7.5=a(1.5) ⇒ a=5
y=5*(1.5^x)
Answer; y=5*1.5^x
Answer:
6.14
Step-by-step explanation:
Find area of shaded region:
regtangle area - circle area = shaded area
Regtangle area:
3x3=9
Circle area:
Pi (3.14) x radius x radius= 3.14
area all together if shaded region
9-3.14=6.14
