Answer:

-101 feet

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the relevant relation is ...

Tan = Opposite/Adjacent

Opposite = Adjacent × Tan

height = (0.5 × 5280 ft) × tan(47°) ≈ 2831 ft

The usual relation between estimates and errors is ...

error = estimate - actual

Then ...

actual = estimate - error

For the given angle and error, the actual angle is ...

actual angle = 47° -(-1°) = 48°

actual height = (2640 ft)·tan(48°) ≈ 2932 ft

Then the change in the height of the mountain due to the error is ...

2831 ft -2932 ft = -101 ft

The error of -1° in angle estimate creates an error of -101 ft in the height estimate.

Identify the graph of 4x^2+5y^2=20 for T(5,-6) and write an equation of the translated or rotated graph in general form. (pictur

NikAS [45]

Answer:

b. ellipse; $4x^2+5y^2-40x+60y+260=0$

Step-by-step explanation:

The graph of $4x^2+5y^2=20$ an ellipse because the coefficients of the quadratic terms are not the same.

This ellipse is centered at the origin. If this ellipse is translated so that its center is now at $(5,-6)$ .

Then the translated ellipse will now have equation.

$4(x-5)^2+5(y+6)^2=20$

We expand to get;

$4(x^2-10x+25)+5(y^2+12y+36)=20$

$4x^2-40x+100+5y^2+60y+180=20$

$4x^2+5y^2-40x+60y+100+180-20=0$

$4x^2+5y^2-40x+60y+260=0$
