Your function is: f(x)=\frac{1}{2}\cos \Big( \frac{1}{4x}\Big) -1

Domain: $(-\infty, +\infty)-\{ 0 \}$ or $R-\{ 0 \}$

Range: $[-\frac{3}{2}, -\frac{1}{2}]$

Midline: $y=-1$

A basket contains four apples, three pears, two peaches, if we draw one fruit from the basket, what is the probability of gettin
Annette [7]

Answer:

The probability of getting a peach or an apple is 2/3.

Step-by-step explanation:

There are two peaches and four apples, so six fruits we want to know the probability of getting, and there are also three pears, which means we have nine fruits total. The chance of getting an apple or a pear is six out of nine, which simplifies to two out of three.

What is the radius of a circle with an area of 113.04 cubic inches? Use 3.14 for pi.
Ipatiy [6.2K]

Answer: 6 inches.


Step-by-step explanation:

1. You must use the formula for calculate the area of a circle, which is shown below:

A=3.14r^{2}

2. You know the area of the circle, therefore, you can solve for the radius, as following:

3.14r^{2}=A\\r^{2}=\frac{A}{3.14}\\r=\sqrt{\frac{A}{3.14}}

3. Now, you must substitute the value of the area into the equation above. Then, you obtain the following result:

r=\sqrt{\frac{113.04in^{2}}{3.14}}\\r=6in

One angle of a triangle measures 140°. The other two angles are in a ratio of 7:13. What are the measures of those two angles?
nexus9112 [7]
The unknown angles are in a ratio of 7 to 13.

Let 7x represent the smaller measure.Then, 13x represents the larger measure.
7x + 13x + 140 = 180
20x + 140 = 180
20x = 40
x = 2

7x = 7 * 2 = 14

13x = 13 * 2 = 26


The measures are 14 degree and 26 degrees.
