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.

The city of Orlando’s building a dog park in downtown Orlando dog park will be triangular shaped as shown on the coordinate plan

kiruha [24]

Answer:

Perimeter of the dog park = 15.4 yards

Step-by-step explanation:

Coordinates of the vertices of the given triangle are,

P(1, 2), Q(1, 6), R(-4, 2)

Since distance between the two points $(x_1, y_1)$ and $(x_2,y_2)$ is,

d = $\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Length of PQ = $\sqrt{(1-1)^2+(2-6)^2}$

PQ = 4

Length of PR = $\sqrt{(1+4)^2+(2-2)^2}$

PR = 5

Length of QR = $\sqrt{(1+4)^2+(6-2)^2}$

QR = $\sqrt{25+16}$

= $\sqrt{41}$

= 6.4 yards

Therefore, perimeter of the given triangle = PQ + QR + PR

= 4 + 6.4 + 5

= 15.4 yards

Dennis_Churaev [7]

Answer:

x^2+5x-14

Step-by-step explanation:

you multiply both equations so that you get:

x^2-2x+7x-14

and then you simplify it to:

x^2+5x-14

May anyone please help on these 2,Thank you so much,ill try to mark brainliest answer if i can

Answer:

To the first question the answer would be > because you can change -3/4 to -9/12. Since these are negative numbers -5 is greater than -9.

The answer the second one would be B because I change all the fractions to decimals and 6/11 equals 0.54545454 and goes on and on So it was the greatest number (in decimal form). Also negaitve numbers are the least. :) Hope this helps

Please help me find the length!!

galben [10]

So, this would be a common circle question.

First, 20 degrees from a circle's curcumference would be 20/360, which is 1/18.

This means that the length of the arc of AB should be 1/18 of the circumference.

The formula for the circumference it 2pi*r

2*pi*27=54pi

54pi* 1/18= 6 pi
