Vladimir [108]

Answer:

The expression of h as function of x is h = $\sqrt{(d + 5500) (d - 5500)}$

Step-by-step explanation:

Given as :

The distance of blimp (AB) = 5500 feet

The slanted distance to the pagoda (BC) = d feet

The horizontal distance (AC) = h

Let the angle made between slanted distance and horizontal distance be Ф

So , cos Ф = $\frac{AC}{BC}$ = $\frac{h}{d}$

And sin Ф = $\frac{AB}{BC}$ = $\frac{5500}{d}$

∵, cos²Ф = 1 - sin²Ф

So, $(\frac{h}{d})^{2}$ = $1 - (\frac{5500}{d})^{2}$

Or, $(\frac{h}{d})^{2}$ = $(\frac{d^{2}- 5500^{2}}{d^{2}})$

Or, h² = d² - 5500²

∴ h = $\sqrt{d^{2}- 5500^{2}}$

Or, h = $\sqrt{(d + 5500) (d - 5500)}$

Hence The expression of h as function of x is h = $\sqrt{(d + 5500) (d - 5500)}$ Answer

You subtract two because the 21 accounts for it and then whatever you have left multiplied by 4 and added to 21 is the amount of years after conversion.

Answer:

Question 7

Answer : 1200 inches squared

Question: 8

Answer: 84 centimeters squared

Question: 9

Answer: 2304 feet squared

Step-by-step explanation:

1) Q7: Parallelogram

A=BH

base 30 inch X height 40 inch = 1200 inches squared

2) Q8: Rhombus

A=pq /2

Multiply the two diagonals then divide by 2

Diagonals 14 cent X Diagonal 12 cent divided by 2 = 84 centimeters squared

3) Q9: Trapezoid

A= (B1+B2)H/2

Add the two bases times the height divide by 2

gives you:

2304 feet squared
