Let f(x)= 100 / −10+ e^ −0.1x . What is f(−6) ?
bija089 [108]

The value of f(-6) is -12.2

Explanation:

Given that the function f(x)=\frac{100}{-10+e^{-0.1\left(x\right)}}

We need to determine the value of f(-6)

The value of f(-6) can be determined by substituting the value for x=-6 in the function and simplify the function.

Hence, let us substitute x=-6 in the function, we get,

f(-6)=\frac{100}{-10+e^{-0.1\left(-6\right)}}

Let us apply the rule -\left(-a\right)=a , we get,

f(-6)=\frac{100}{-10+e^{0.1\left(6\right)}}

Multiplying the numbers, we get,

f(-6)=\frac{100}{-10+e^{0.6}}

The value of e^{0.6}=1.822

Substituting the value of e^{0.6}=1.822 , we get,

f(-6)=\frac{100}{-10+1.822}

Subtracting the denominator, we have,

f(-6)=\frac{100}{-8.178}

Dividing, we have,

f(-6)=-12.228

Rounding off to the nearest tenth, we have,

f(-6)=-12.2

Thus, the value of f(-6) is -12.2

I'm not sure what trig function to use. Someone please help, and please answer sedulously, and not just for points. Thank you in
Alex Ar [27]

Answer:

w = 6.7451

x = 8.0805

Step-by-step explanation:

Find W

Tan(56) = opposite / adjacent

opposite = 10

Adjacent = w

Tan (56) = 10/w

w*Tan(56) = 10

w = 10 / tan(56)

w = 10/ 1.4826

w = 6.7451

Find x

Tan (34) = 10 / (w + x)

Tan (34) = 0.6745

(w + x) * Tan(34) = 10

w + x = 10 / tan(34)

w+ x = 10 / 0.6745

w + x = 14.826

But we found w = 6.7451

6.7451 + x = 14.826

x = 14l826 - 6.7451

x = 8.0805
