Answer:
h = 9.87 cm
Step-by-step explanation:
Given that,
Base, b = 8 cm
Height = h
Angle,
We need to find the value of h. We can use trigonometry to find h.
So, the height of the triangle is 9.87 cm.
34= 21 +2w
34-21=2w
13= 2w
13:2=w
6.5=w
In a year she will have 1290$ because if she gets paid every 2 months and there are 12 months, 12/2 equals 6 times she gets paid a year. So 215 times 6 is 1290
D is correct. f(-2) the number in the bracket is an input so..
whenever you see an X in the function replace it with -2
f(-2)=2*3^-2
3^-2 is 1/9
1/9 * 2 is simply 2/9
so D is correct
If the y-intercepts are the same, the two equations represent the same line and there are INFINITELY MANY SOLUTIONS
