Answer: $7.93$

Step-by-step explanation:

Given

$f(x)$ is an exponential function. Suppose $f(x)$ is $ae^{bx}$

$f(1.5)=5\ \text{and}\ f(7.5)=79$

$\Rightarrow 5=ae^{1.5b}\\\Rightarrow \ln 5=\ln a-1.5b\quad \ldots(i)$

Similarly,

$\Rightarrow 79=ae^{7.5b}\\\Rightarrow \ln(79)=\ln a+7.5b\quad \ldots(ii)$

Subtract (i) and (ii)

$\Rightarrow \ln (79)-\ln (5)=9b\\\Rightarrow \ln (\frac{79}{5})=9b\\\\\Rightarrow b=\dfrac{\ln (\frac{79}{5})}{9}\\\\\Rightarrow b=0.3066$

Insert the value of $b$

$\Rightarrow 5=ae^{0.46}\\\Rightarrow a=5\times 0.6312\\\Rightarrow a=3.156\approx 3.16$

So, the function becomes

$\Rightarrow f(x)=3.16e^{0.3066b}$

$\Rightarrow f(3)=3.16e^{0.3066\times 3}\\\Rightarrow f(3)=7.927\approx 7.93$

Answer:

s=5

Step-by-step explanation:

As you can see, you have a whole block that is 20. Then you have another block that is broken down to 4 squares.

So....

4s=20

divide 4 to 4s

divide 4 by 20

so s=5

4=0.25(w−4.3)<br><br> Solve for w.

Triss [41]

Solving:
$4 = 0.25(w - 4.3)$
Delete the first parentheses by the distributive property, with the distributive property, we multiply the '0.25' first:
$4 = 0.25w - 1.075$
Now, put the numbers with letter (incognito) to the right and numbers without letter to the left, changing the signal when changing sides.
$- 0.25w = - 4 - 1.075$
$- 0.25w = - 5.075$
simplify by (-1)
$- 0.25w = - 5.075\:*(-1)$
$0.25w = 5.075$
$w = \frac{5.075}{0.25}$
$\boxed{\boxed{w = 20.3}}\end{array}}\qquad\quad\checkmark$
