Answer:

B 23°

Step-by-step explanation:

(3x + 1) + (2x - 3) + 9x = 180

14x = 182

x = 13

Write an equation for the exponential function represented in the table below.

Neko [114]

Answer:

$f(x)=-\frac{1}{2}(10^x)$

Step-by-step explanation:

Let the exponential function be $f(x)=a(b^x)$ .

When x=0, $f(0)=-\frac{1}{2}$

$-\frac{1}{2}=a(b^0)$

$a=-\frac{1}{2}$

The function now becomes $f(x)=-\frac{1}{2}(b^x)$

When x=1, f(1)=-5

This implies that:

$-5=-\frac{1}{2}(b^1)\\ \implies b=10$

Therefore the equation for the exponential function represented in the table below is $f(x)=-\frac{1}{2}(10^x)$

patriot [66]

Answer:

s = $\frac{3}{10}$ m

Step-by-step explanation:

Given s varies directly with m then the equation relating them is

s = km ← k is the constant of variation

To find k use the condition s = 9 when m = 30 , thus

9 = 30k ( divide both sides by 30 )

k = $\frac{9}{30}$ = $\frac{3}{10}$

s = $\frac{3}{10}$ m ← equation of variation
