Answer:
A
Step-by-step explanation:
The gym membership is going to cost 40 initially plus 22.50 for each month after.
The total cost for the gym can be expressed as 40+22.50m
The martial arts class is going to cost 26 initially plus 16 for each month after.
The total cost for the martial arts class can be expressed as 26+16m
Now we have to combine these to get the total cost for both the gym and the martial arts class:
(40+22.50m) + (26+16m) = 66 + 38.50m (option A)
The Cube Root Of -343 is ( -7)
The diameter of a circle passes through the middle
It is like 9>3. It is a difference between two expressions
Using the slope concept, it is found that the angle between the ladder and the floor will be of 33.69º.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.
In this problem, we have that:
- The vertical distance is the height of h.
- The horizontal distance is of 3m.
Hence:
tan(45º) = h/3.
1 = h/3.
h = 3 m.
If the ladder slides 1 m down, the height will be of 2m, hence the angle will be given as follows:
