Sliva [168]

Answer:

$a_1=12$

Step-by-step explanation:

Assuming the geometric series is

$\sum_{n=1}^{\infty} 12*(-\frac{1}{3} )^{n-1}$

then nth term is

$a(n)=12*(-\frac{1}{3} )^{n-1}$ ,

and the first term is found when $n=1$ :

$a_1=12*(-\frac{1}{3} )^{1-1}=12*(-\frac{1}{3} )^0\\\\\boxed{a_1=12}$

<h3>How to calculate the surface area of a prism</h3>

The formula for calculating the total surface area is expressed as:

Area = 4(area of triangle)

Find the area of the triangle

A = 0.5(6)(5.2)

A =3(5.2)

A = 15.6 square inches

TSA = 4(15.6)
TSA = 62.4 square inches

Hence the amount of wrapping paper he uses is 62.4 square inches

A road is inclined at an angle of 5°. After

Scorpion4ik [409]

Answer:

464 feet

Step-by-step explanation:

The Sine of the angle of inclination gives the increase in altitude.

This is because the Sine of an angle is equal to the Opposite side divided by the Hypotenuse side. i.e

Sin Ф = Opposite ÷ Hypotenuse

Sin 5° = O ÷ 5328

0·08716 = O ÷ 5328

Make O the subject and multiply every fraction by 5328

(0·08716/1 × 5328)= (O/5328 × 5328)

464·388 = O

∴ The increase in altitude is 464·388 feet

This is supposed to be to the nearest foot so we round off

464·388 becomes 464 feet
