$0.09 per cookie

first, you subtract $2.25 from $5.40 to get $3.15.
then, you divide $3.15 by 35 and you get $0.09.

Hope this helps!(:

Let f(x)=x. The graph of f(x) is transformed into the graph of g(x) by a vertical stretch of 4 units and a translation of 4 uni

Mrac [35]

Answer:

$g(x) = 4x + 4$

Step-by-step explanation:

The given function is f(x)=x.

If we stretch vertically by a factor of 4 and a translation of 4 units up then the new function becomes

$g(x) = 4f(x) + 4$

But f(x)=x

We substitute to obtain the equation of g(x) as

$g(x) = 4x + 4$

The half-life of cesium-137 is 30 years. Suppose we have a

VMariaS [17]

(a) If $y(t)$ is the mass (in mg) remaining after $t$ years, then $y(t) = y(0) e^{kt}=100e^{kt}.$

$y(30) = 100 e^{30k} = \frac{1}{2}(100) \implies e^{30k} = \frac{1}{2} \implies k = -(\ln 2) /30 \implies \\ \\
y(t) = 100e^{-(\ln 2)t/30} = 100 \cdot 2^{-t/30}$

(b) $y(100) = 100 \cdot 2^{-100/30} \approx \text{9.92 mg}$

(c)
$100 e^{- (\ln 2)t/30} = 1\ \implies\ -(\ln 2) t / 30 = \ln \frac{1}{100}\ \implies\ \\ \\
t = -30 \frac{\ln 0.01}{\ln 2} \approx \text{199.3 years}$

Consider the function. f(x)= -2/3x-24 Which conclusions can be drawn about f–1(x)? Select two options. f–1(x) has a slope of -2/

disa [49]

Answer:

(D) $f^{-1}{(x$) has an x-intercept of (-36, 0).$

(E) $f^{-1}{(x)$ has a range of all real numbers.

Step-by-step explanation:

Given the function: $f(x)= -\dfrac23x-24$

$f(x)+24= -\dfrac23x\\$Multiply both sides by $ -\dfrac32\\x=-\dfrac32(f(x)+24)\\f^{-1}(x)=-\dfrac32f(x)-36$

When y=f(x)=0

$f^{-1}(x)=-\dfrac32(0)-36\\f^{-1}(x)=-36$

Therefore, $f^{-1}(x)$ has a x-intercept of -36$

Also, $f^{-1}(x)$ has a range of all real numbers.

Therefore, Options D and E are correct.

Which property is illustrated? 8(a + c) = 8a+ 8c

alekssr [168]

Answer:

Distributive property

Step-by-step explanation:

Here, we want to evaluate the property illustrated

From what we can see, we have that each of the inner values are multiplied by the outside value

This is simply a display of distributivity

We can conclude that we have a right distributive property in place here
