Answer:
Step-by-step explanation:
y=a*b^x
pass thro' (1, 7.5) n (3, 16.875)
at x=1, y=a*b=7.5
at x=3, y=a^b^3=16.875
dividing, a*b^3/a*b=16.875/7.5
b^2=2.25
b=+1.5 or -1.5
a=7.5/b
a=5 or -5
y=5*(1.5)^x
or
y=(-5)*(-1.5)^x
Distribute the 10 and 15 through the parenthesis
10(x + 4) + 15(x + 1)
10x + 40 + 15x + 15
25x + 55
75m + 800 = 95m + 500
Solve that equation
Which should get you m=15
15 is your answer
Well let's remember csc = hypotenuse/opposite
Let's use the distance formula to find the length of the hypotenuse.
<span><span><span><span>√(0−−8)^</span>2</span>+<span><span>(−6−0)^</span>2
</span></span>√</span><span><span><span><span>(0+8)^</span>2</span>+<span><span>(−6+0)^</span>2
</span></span>√</span><span><span><span><span>(8)^</span>2</span>+<span><span>(−6)^</span>2
</span></span>√</span><span><span>64+36
</span>√</span><span>100
H = 10
so csc = 10/opposite
Now to find the opposite length using distance formula
</span>√(0−−8)^2+(0−0)^2
√(0+8)^2+(0+0)^2
√(8)^2+(0)^2
√64+0
√64
O = 8
So csc = 10/8 or 1.25
