Answer:

fraction 1 over 2 (18 × 4) = 36

$\because$ Area of standard triangle

$= \frac{1}{2} \times base\times height.$

Where,

Base of triangle = lenght of rectangle = 18 feet

Height of triangle = width of rectangle = 4 feet

How do you find DE, Round to nearest 10th

Sergeu [11.5K]

Answer: $DE\approx6.0$

Step-by-step explanation:

Observe in the figure given in the exercise that four right triangles are formed.

In this case you can use the following Trigonometric Identity to solve this exercise:

$cos\alpha=\frac{adjacent}{hypotenuse}$

From the figure you can identify that:

$\alpha =53\°\\\\hypotenuse=10\\\\adjacent=BE=DE$

Then, you can substitute values:

$cos(53\°)=\frac{DE}{10}$

The next step is to solve for DE in order to find its value. This is:

$10*cos(53\°)=DE\\\\DE=6.01$

Finally, rounding the result to the nearest tenth, you get that this is:

$DE\approx6.0$

Consider the following function. f(x) = 1/x, a = 1, n = 2, 0.6 ≤ x ≤ 1.4 (a) Approximate f by a Taylor polynomial with degree n

Xelga [282]

Answer:

y - 1 = 0

Step-by-step explanation:

move constant to the left by adding its opposite to both sides y - 1 = 1 - 1

the sum two opposites equals 0

y =1
