I=(r)(t)(P)P=principalr=rate in decimalt=timei=interest
so just plug in what you know to solve for what you don't know
first oneI=(0.05)(3)(100)
I=15
2nd one20=(0.04)(t)(500)20=20tdivide by 20 both sides1=tt=1
3rd one35=(0.10)(7)(P)35=0.70Pdivide both sides by 3550=PP=50
4th one6=(r)(2)(200)
6=400rdivide both sides by 4000.015=rconvert to percent1.5%=r
We are given a figure that is projected to be a rhombus that is a quadrilateral that has 4 equal sides. in this case, the length of the sides is equal to sqrt (a2 + b2) through the distance formula. There are four equal sides so the perimeter is equal to D) 4√(a^2 + b^2)
Answer:
x = 14; y = 8
Step-by-step explanation:
A perpendicular intersection means an intersection between 2 lines, forming angles of 90°. Then:
7x - 8 = 90°
11y + 2 = 90°
7x - 8 = 90
7x = 90 + 8
7x = 98
x = 98/7
x = 14
11y + 2 = 90
11y = 90 - 2
11y = 88
y = 88/11
y = 8
I hope I've helped you.
The angle of depression is the same as the base angle next to the right angle because of alternate interior angles. Use the tangent ratio:
. The angle of depression, therefore, is 27
You can use either the quadratic formula or you can factor it.
3Y(y+8)=0
so 3Y=0 Y=0
Y+8=0 Y=-8
