Mathematics
1 answer:
PSYCHO15rus [73]3 years ago
4 0

Answer:

The answer is below

Step-by-step explanation:

9) The area of the platform = length * width = 9 m * 12 m = 108 m²

Area = 108 m²

11) 1 km² = 1 km × 1 km = 1000 m × 1000 m = 1000000 m²

But 1 hectare = 10000 m², hence:

1000000 m² = 1000000 m² / 10000 m² per hectare = 100 hectares

1 km² = 100 hectares

12) Area of each paper = 16 cm * 12 cm = 192 cm²

There are 48 sheets, hence:

Total area of sheets = 192 cm² * 48 = 9216 cm²

13) Area of each tile = 12 cm * 10 cm = 120 cm²

The kitchen contains 500 tiles, therefore:

Area of kitchen = 120 cm² * 500 tiles = 60000 cm²

1 m² = 10000 cm²

60000 cm² = 60000 cm² / 10000 cm² per m² = 6 m²

Area of kitchen = 6 m²

What are the explicit equation and domain for a geometric sequence with a first term of 2 and a second term of −8? an = 2(−8)n −
jonny [76]
Hello,

The question is
<span>"What are the explicit equation and domain for a geometric sequence with a first term of 2 and a second term of −8?"

It is a geometric sequence =>U(2)=U(1)*r==>-8=2*r ==>r=-4

U(1)=2=2*(-4)^0
U(2)=-8=2*(-4)=2*(-4)^1
U(3)=32=-8*(-4)=2*(-4)(-4)=2*(-4)^2
U(4)=-128=32*(-4)=2*(-4)^3
...
U(n)=2*(-4)^(n-1) where n>=1.

Nine fourths minus two thirds
Yuki888 [10]

Answer:

1 \frac{7}{12}  \: or \: 1.583

Step-by-step explanation:

nine fourths is also

\frac{9}{4}

two thirds is also

\frac{2}{3}

subtract,

\frac{9}{4}  -  \frac{2}{3}

L.C.M = 12

\frac{27 - 8}{12}

\frac{19}{12}

1  \frac{7}{12}  \: or \: 1.583

Use the definition of the derivative to differentiate f(x)= In x
WINSTONCH [101]

By def. of the derivative, we have for y = ln(x),

\displaystyle \frac{dy}{dx} = \lim_{h\to0} \frac{\ln(x+h)-\ln(x)}{h}

\displaystyle \frac{dy}{dx} = \lim_{h\to0} \frac1h \ln\left(\frac{x+h}{x}\right)

\displaystyle \frac{dy}{dx} = \lim_{h\to0} \ln\left(1+\frac hx\right)^{\frac1h}

Substitute y = h/x, so that as h approaches 0, so does y. We then rewrite the limit as

\displaystyle \frac{dy}{dx} = \lim_{y\to0} \ln\left(1+y\right)^{\frac1{xy}}

\displaystyle \frac{dy}{dx} = \frac1x \lim_{y\to0} \ln\left(1+y\right)^{\frac1y}

Recall that the constant e is defined by the limit,

\displaystyle e = \lim_{y\to0} \left(1+y\right)^{\frac1y}

Then in our limit, we end up with

\displaystyle \frac{dy}{dx} = \frac1x \ln(e) = \boxed{\frac1x}

In Mathematica, use

D[Log[x], x]

cow is tied to a tree on grazing land with a 9 -meter rope What is the longest distance around that it can cover ?​
Sholpan [36]
Radius = 9m
Diameter = 18 m
Area = 254.34 squared m
Circumference = 56.52 m

I’m guessing is asking for the circumference because it says around
