sin 45 = opp/hyp
sin 45 = 4 / y
y = 4/sin 45
y = 4 /((sqrt2)/2)=4* sqrt(2)
tan 45 =opp/adj
tan 45 = 4/(x-3)
1 = 4/(x-3)
x-3 = 4
x=7
B
Answer:
5.264 * 10^4
Step-by-step explanation:
We put a decimal point to the right of the number, so
52640.
Then we move it to the left until we get a number that is between 1 and 10.
5.2640
This was four hops to the left.
We can remove the trailing 0, and write
5.264 * 10^4
10^4 because of the four hops
Answer:

Step-by-step explanation:
1
The area of a rectangle = length × width
2
To find the width, divide the area by the length
3
width =
= 
To simplify divide each term on the numerator by 3x
=
+
= x + 3 ← width
F(4)=3(4)+2
f(4)=12+2
f(4)=14
