Answer:

Step-by-step explanation:

1 km= 1000m

1.5 km = 1 x 1000 + 500

1000 + 500

1500m

1500 m : 250 m

750 m : 125 m

150 m : 25 m

30 m : 5 m

6 m : 1m

A company designs a logo using a kite figure around the letter t. The logo is 12 centimeters wide and 16 centimeters tall. What

Temka [501]

Answer:

96 sq. cm.

Step-by-step explanation:

A "kite" has 2 diagonals, which are the "width" and "height" of the kite.

Using diagonals, the area of a kite is given by $A=\frac{pq}{2}$

Where

A is the area

p,q are the width and height, respectively

From the problem given, p is 12 and q is 16, so the area is:

$A=\frac{pq}{2}\\A=\frac{(12)(16)}{2}\\A=96$

Thus, the area is 96 sq. cm

It is estimated that world reserves of oil currently stand at 2625

seraphim [82]

Answer:

35.4 years

Step-by-step explanation:

The annual consumption (in billions of units) is described by the exponential function ...

f(t) = 45.5·1.026^t

The accumulated consumption is described by the integral ...

$\displaystyle\int_0^t{f(x)}\,dx=45.5\int_0^t{1.026^x}\,dx=45.5\left(\dfrac{1.026^t-1}{\ln{1.026}}\right)$

We want to find t such that the value of this integral is 2625, the estimated oil reserves.

2625 = 45.5/ln(1.026)·(1.026^t -1)

2625·ln(1.026)/45.5 +1 = 1.026^t ≈ 1.480832 +1 = 1.026^t

Taking natural logs, we have ...

ln(2.480832) = t·ln(1.026)

t ≈ ln(2.480832)/ln(1.026) ≈ 35.398

After about 35.4 years, the oil reserves will run out.
