What are the coordinates of the orthocenter of LMN ?
Sauron [17]

Answer:

a (1, 2.5)

Step-by-step explanation:

When talking about the orthocenter, you want to make sure that the point you are looking for is in the exact center.  Since coordinate N of the x value is 1, we can safely assume that your top two choices are either a and b.  B wouldn't work since it is not at the exact center which makes your answer A.

Given cos A = 0.25 find angle A in degrees. Round your answer to the nearest hundredth.
Fantom [35]
We have that
cos A=0.25
so
A=arc cos (0.25)-------> using a calculator----> A=75.5225°
Round to the nearest hundredth-----> A=75.52²

Please someone explain how to solve this piecewise function!!!! Im super confused
Xelga [282]

Answer:

From top to bottom:

0, 1, 2, -8, -8

Step-by-step explanation:

We are given the piecewise function:

g(x) = \left\{        \begin{array}{ll}            0.5x+1 & \text{if } x \leq 2 \\            -8 & \text{if } x > 2        \end{array}    \right.

Row 1:

We want to find g(-2).

Since -2 is less than (or equal to) 2, we will use the first equation. Thus:

g(-2)=0.5(-2)+1=-1+1=0

Row 2:

Likewise, 0 is less than or equal to 2. We will continue to use the first equation:

g(0)=0.5(0)+1=1

Row 3:

2 is not less than 2 but it is equal to 2. So we will continue to use the first equation:

g(2)=0.5(2)+1=1+1=2

Row 4 and 5:

Both 4 and 6 are greater than 2. Thus, we will use the second equation. Therefore:

g(4)=-8\text{ and } g(6)=-8

Lol I just answered the same question minutes ago. Here is the answer I gave him/her.


Total Cost : 1800



12 dollars * 16 hours = 192 dollars earned



0.2 percent * 192 = 38.4 dollars saved



A.She earns 192 dollars every week



B.  she will save 38.4 dollars * 7 weeks = 268.8  dollars in a week.



C.  7 days times 4.3 weeks = 30.1 days. 30.1 days * 38.4 = 1,155.84 dollars every month.



D. it will take her  about 2 months to save the money. To be exact: 1.6 months.



Hope this helped!
