Answer:
Inverse of y = 
= 
.
Step-by-step explanation:
Given : f(x) = y = 100 - x²
To find : Find inverse.
Solution : We have given that :
f(x) = y = 100 - x²
Step1) : Replace every x with a y and replace every y with an x .
x = 100 - y².
Step 2): Solve for y
On subtracting 100 from both sides
x - 100 = -y²
On multiplying both side by -1
100 -x = y²
Taking square root both sides and switching sides
y = ± 
.
Step3 ) : Replace y with .
= ± .
Therefore, inverse of y = = ± .
Divide 4100 by 3.
Your answer should be 1366. 6666....
You should estimate and make it 1367.
Answer:
Answer:Option D is correct.Step-by-step explanation:We are given with a solid figure with cuboid in base and square based pyramid in top.we have to find Surface of the figure.Surface Area = Curved surface ares of cuboid + area of base of cuboid + lateral surface area of pyramid.Length of the cuboid, l = 8 cmwidth of the cuboid , w = 8 cm height of the cuboid , h = 11 cm Lateral surface area of pyramid = 4 × Area of a triangle Base of triangle , b = length of cuboid = 8 cmHeight of the triangle ,H = 8 cmSurface Area = 2 × h × ( l+w ) + l × b + 4 × 1/2 × b × H = 2 × 11 × ( 8 + 8 ) + 8 × 8 + 2 × 8 × 8 = 22 × 16 + 64 + 128 = 352 + 192 = 544 cm²Therefore, Option D is correct. Step-by-step explanation:
Answer:
y intercept is (0,-4) slope is 4/2
Step-by-step explanation:
If you plug 0 into x you get the y-intercept, because to for a y-intercept x=0.
The slope is the number attached to the x.
Answer:
15years
Step-by-step explanation:
6000×10×t÷100=9000
600t=9000
t=9000÷600
t=15years
