Answer:
x= 97/3
Step-by-step explanation:
Answer:
1.75 meters² or 175 centimeters²
Step-by-step explanation:
Step 1: Find Area of the Base.
- Base is a square with dimensions of 7cm by 7cm
Step 2: Find the Area of the Triangles.
- Each triangle has a base of 7cm and a height of 9cm.
- 7 x 9 = 63, and 63/2 = 31.5
- 31.5 x 4 = 126 cm²
Step 3: Add the areas together.
- 175 cm²
Thus, the surface area is 1.75 m^2 or 175 cm^2.
Answer:
Step-by-step explanation:
1st let's calculate the decreasing rate & let V₁ be the initial value & V₂ the final's
we know that V₂=V₁.e^(r,t) where r=rate & t-time (& e=2.718)
After t= 2 years we can write the following formula
2350,000=240,000.e^(2r)==> 235,000/240000 = e^(2r) =>47/48=e^(2r)
ln(47/48)=2rlne==> ln(47/48)=2rlne=2r (since lne =1)
r= ln(47/48)/2==>r=-0.0210534/2 =-0.01052 ==> (r=-0.01052)
1) Determine when the value of the home will be 90% of its original value.
90% of 240000 =216,000
Now let's apply the formula
216,000=240,000,e^(-0.01052t), the unknown is t. Solving it by logarithm it will give t=10 years
1.a) Would the equation be set up like so: V=240e^.09t? NON, in any case if you solve it will find t=1 year
2)Determine the rate at which the value of the home is decreasing one year after : Already calculated above :(r=-0.01052)
3)The relative rate of change : it's r = -0.01052
Answer:
158400 meters
Step-by-step explanation:
multiply 3600 by 22 then multiply by 2
