BD is 62 cm because first we have to plug 8 as x and we get BE as 31 and since BE is half of BD then BD would be 31*2 which is 62.
We are required to find the cosine and tangent of 60°. Here we use an equilateral triangle whose side is 2 units, the height of the triangle by Pythagorean theorem will be √3 units, the base of the right angle triangle formed by bisection of the base will be 1 unit.
thus:
tan θ=opposite /adjacent
opposite= √3
adjacent=1
hence:
tan 60=√3/1=√3
cos θ=adjacent/ hypotenuse
adjacent=1
hypotenuse=2
thus
cos 60=1/2
Answer:
There are 525 calories in a banana split.
Step-by-step explanation:
We know that a banana has 80 calories and 5 calories less than this
80 - 5 = 75 calories
is 1/7 that of the calories in a banana split.
This means that the banana split will have 7 times 75 calories
75 * 7 = 525
There are 525 calories in a banana split.
Answer:
and the slope intercept is
Answer:
The form is y=mx+b where m is the slope and b is the y-intercept
1)
y=4/3x-5
2)
y=-3/2x+4
y-intercept is (0,4)
4-1/0-2=3/-2=-3/2
3)
y=-2/3x
y-intercept is (0,0)
0-(-2)/0-3=2/-3=-2/3
4)
y=2x-1
9-3/5-2=6/3=2
y-9=2(x-5)
y=2x-10+9
y=2x-1
