<u>Intro.</u>

Before we solve the areas of the triangles, let's review the key points.

<u>Key points:</u>

  • Area of triangle: 1/2 x Base x Altitude

<u>Solution (4):</u>

  • 1/2 x 13.5 x 10.6
  • => 1 x 13.5 x 5.3
  • => 71.55 cm²

<u>Solution (5):</u>

  • 1/2 x 7.2 x 4
  • => 1 x 7.2 x 2
  • => 14.4 yd²

<u>Solution (6):</u>

  • 1/2 x 6 x 5.2
  • => 1 x 3 x 5.2
  • => 15.6 ft²

Hoped this helped!

Find the domain and range of the<br>function y = f(x)= √x-2<br><img src="https://tex.z-dn.net/?f=%20%5Csqrt%7Bx%20-%202%7D%20" i
Over [174]

Answer:

3x-x+2=4

Step-by-step explanation:

The domain of f(x)=2^x would be the x values. This would include all values that you can input as x in order to make this problem work. The domain of a function is usually all real numbers. The range of f(x)=2^x would be the y values. This would include all values that would be the output for the y value. An example of this would be if you used 2 as x then the function would read f(x)=2^2. The y would equal 4 which would be included in the range of this function. To find the domain and range of the inverse you would follow the proper steps to get the inverse of the function which would be x=2^y. The domain would be the x values and the range would be the y values. If you put 4 as x which would be your input for the domain you would get 2^4 = 16 for the y which would be the range.

Find a Cartesian equation for the curve.
Galina-37 [17]

r = 3sec( \alpha ) \\ r =  \frac{3}{cos( \alpha )}

x = rcos( \alpha ) \:  \:  \:  \:  \:  \:  \: cos( \alpha ) =  \frac{x}{r}

r =  \frac{3}{ \frac{x}{r} }  \\ r =  \frac{3r}{x}  \:  \:  \:  \:  \:  \: x = 3 \\ line

Solve this .....................​
ycow [4]

Answer:

Step-by-step explanation:  3root5x^2 + 25x - 10root5 = 0

3xroot5 + 25x - 10root5 = 0      [ root x^2 = x]

28x root5 = 10 root5         [ -10root5 turns to 10 root5 when transferred to RHS]

28x root 5/root5 =10

28x=10

x = 10/28

x = 0.35

Hope it helped u,

pls mark as the brainliest
