A triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle Thus, the triangle is not acute because 2² + 4² < 5².

<h3>What is the acute angle?</h3>

An acute angle is defined as the measure of an angle that is less than 90 degrees.

The square of the hypotenuse of a right triangle with the given sides would be 2² +4² = 20.

So, that hypotenuse would be √20, about 4.47.

The long side of this triangle is longer than that, hence the angle opposite is larger than 90°. The triangle with sides 2, 4, and 5 is an obtuse triangle.

The triangle is not acute because 2² + 4² < 5²

If the combined area of the white and orange regions is 100π, what is the area of ONLY the orange region?
scoundrel [369]
We know the combined area is 100π, and the combined area includes the white section as well as the orange section.

now, if we take the area of the white circle, and "subtract" it from the combined area, we're in effect, making a whole in the larger circle, and what's leftover is just the orange part, because the white would have been subtracted out,

\bf \textit{area of a white circle}\\\\&#10;A=\pi r^2\quad &#10;\begin{cases}&#10;r=radius\\&#10;-----\\&#10;r=6&#10;\end{cases}\implies A=\pi 6^2\implies A=36\pi &#10;\\\\\\&#10;\stackrel{combined~area}{100\pi }~~-~~\stackrel{white~circle's~area}{36\pi }\implies \stackrel{orange~section}{64\pi }

Which of these statements is true for f(x) = (1/2)^x
Ann [662]
<h3>Answer:  D) The y intercept is (0,1)</h3>

This can be confirmed by plugging x = 0 into the function to find that...

y = (1/2)^x

y = (1/2)^0

y = 1

Recall that any nonzero value to the 0th power leads to 1. So we can say x^0 = 1 as long as x is not zero.

---------------

Extra info (optional section):

  • We can rule out choice A because negative x values work in the domain. For instance, if x = -1, then it leads to y = (1/2)^x = (1/2)^(-1) = 2. The negative exponent will apply the reciprocal operation to the base fraction.
  • Choice B can also be ruled out because the range is y > 0. Or you could note that it is possible to get positive y values smaller than 1/2. Try x = 2 and you'll see it leads to y = 1/4 which is not greater than 1/2.
  • Choice C is false as well. The function f(x) = (1/2)^x is decreasing throughout the domain. A graph visually would show this due to it going downhill when moving from left to right. A table of values is a non-visual way to see we have a decreasing function. The table would show that y decreases when x increases.
