Answer:
[tex]\frac{100}{9}[/tex] is the answer.
Step-by-step explanation:
Well the first thing we would do is simplify all the exponents first inside the parenthesis. So 2^-3 is equal to 1/8. To solve negative exponents you would just divide the number instead of multiply, so 2 divided by 2 divided by 2 is equal to ⅛ or .125
Next would be to do the 2^-9. This would equal 1/512
Now would be to simplify 5^0. Anything to the power of 0 is always one. So now we simplify all the products meaning 7*5*2 and 7*3.
Now we would simplify both fractions.

Using the exponential function 2x + 3, what is the average rate of change between the values 1 ≤ x ≤ 5?
explain your answer step by step
Rate of change of the function: 60
Step-by-step explanation:
The exponential function in this problem is
[tex]f(x)=2^{x+3}[/tex]
The rate of change of a function between a certain interval [tex]x_1 \leq x \leq x_2[/tex] is given by
[tex]r=\frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]
where
[tex]f(x_1)[/tex] is the value of the function calculated in [tex]x_1[/tex]
[tex]f(x_2)[/tex] is the value of the function calculated in [tex]x_2[/tex]
In this problem, the interval is
[tex]1\leq x \leq 5[/tex]
So we have:
[tex]f(x_1)=f(1)=2^{1+3}=2^4=16[/tex]
and
[tex]f(x_2)=f(5)=2^{5+3}=256[/tex]
Therefore, the rate of change is:
[tex]r=\frac{256-16}{5-1}=60[/tex]

Answer:+5 or just 5
Step-by-step explanation:
If m (x) = StartFraction x + 5 Over x minus 1 EndFraction and n(x) = x – 3, which function has the same domain as (m circle n) (x)?
Question:
If m (x) = StartFraction x + 5 Over x minus 1 EndFraction and n(x) = x – 3, which function has the same domain as (m circle n) (x)?
h (x) = StartFraction x + 5 Over 11 EndFraction
h (x) = StartFraction 11 Over x minus 1 EndFraction
h (x) = StartFraction 11 Over x minus 4 EndFraction
h (x) = StartFraction 11 Over x minus 3 EndFraction
Answer:
Option C: [tex]h(x)=\frac{11}{x-4}[/tex] has the same domain as [tex]$(m \circ n)(x)$[/tex]
Explanation:
It is given that [tex]m(x)=\frac{x+5}{x-1}[/tex] and [tex]n(x)=x-3[/tex]
Let us find the domain of [tex]$(m \circ n)(x)$[/tex]
[tex]$\begin{aligned}(m \circ n)(x) &=m(n(x))\\&=m(x-3) \\ &=\frac{(x-3)+5}{(x-3)-1} \\ &=\frac{x+2}{x-4} \end{aligned}$[/tex]
Now, let us equate the denominator equal to zero to determine the domain.
[tex]$x-4=0$[/tex]
[tex]x=4[/tex]
Thus, the function becomes undefined at the point [tex]x=4[/tex]
Hence, the domain of [tex]$(m \circ n)(x)$[/tex] is [tex]$(-\infty, 4) \cup(4, \infty)$[/tex]
Now, we shall find the function which has the same domain as [tex]$(m \circ n)(x)$[/tex]
Option A: [tex]h(x)=\frac{x+5}{11}[/tex]
The function h(x) has the domain of set of all real numbers [tex]$-\infty<x<\infty$[/tex]
Thus, the interval [tex](-\infty,\infty)[/tex] is not the same domain as [tex]$(-\infty, 4) \cup(4, \infty)$[/tex]
Hence, Option A is not the correct answer.
Option B: [tex]h(x)=\frac{11}{x-1}[/tex]
Equating the denominator equal to zero, the function becomes undefined at the point [tex]x=1[/tex]
Thus, the function h(x) has the domain of [tex]$(-\infty,-1) \cup(-1, \infty)$[/tex] is not the same domain as [tex]$(-\infty, 4) \cup(4, \infty)$[/tex]
Hence, Option B is not the correct answer.
Option C: [tex]h(x)=\frac{11}{x-4}[/tex]
Equating the denominator equal to zero, the function becomes undefined at the point [tex]x=4[/tex]
Thus, the function h(x) has the domain of [tex]$(-\infty, 4) \cup(4, \infty)$[/tex] is the same domain as [tex]$(-\infty, 4) \cup(4, \infty)$[/tex]
Hence, Option C is the correct answer.
Option D: [tex]h(x)=\frac{11}{x-3}[/tex]
Equating the denominator equal to zero, the function becomes undefined at the point [tex]x=3[/tex]
Thus, the function h(x) has the domain of [tex]$(-\infty,3) \cup(3, \infty)$[/tex] is not the same domain as [tex]$(-\infty, 4) \cup(4, \infty)$[/tex]
Hence, Option D is not the correct answer.

What is the area of the following circle?
the diameter is 10.
Answer: The area of the circle with a diameter of 10 cm is 78.5 cm2.
Answer: 78.5 units²
Step-by-step explanation: To find the area of a circle, start with the formula for the area of a circle.
Area = πr²
Notice that here, we're given the diameter instead of the radius. It's important to understand that the radius is equal to half of the diameter so the radius of this circle will be equal to half of 10 or 5.
So plugging into the formula, we have (π)(5)².
A common mistake is to plug 10 into the formula but remember that we must plug in the radius and not the diameter.
Multiplying, (5)² is equal to 5 x 5 or 25 so we have 25π.
So the area of the circle is 25π.
Now, remember that π is approximately equal to 22/7 or 3.14 so we can estimate the area of the circle by plugging in 3.14 for π.
So we have (25)(3.14) which is equal to 78.5 units².
Since there were no labels, I just add units to the end.
So the area of the circle is approximately equal to 78.5 units².

Step-by-step explanation:
convert the rate 175 miles per 5 gallons to feet per quart.
Answer: 46200 feet per quart.
Step-by-step explanation:
We know that 1 gallon = 4 quarts
1 mile = 5280 feet
Therefore , 5 gallons = 5 x 4 quarts
= 20 quarts (i)
175 miles = 175 x 5280 feet
i.e. 175 miles = 924000 feet (ii)
Now , 175 miles per 5 gallons = [tex]\dfrac{\text{ 175 miles }}{\text{5 gallons}}[/tex]
[tex]=\dfrac{ 924000 \text{ feet}}{\text{20 quarts}}[/tex] [From (i)and (ii)]
[tex]\dfrac{46200\text{ feet }}{1\text{ quart}}\\\\=46200\text{ feet per quart}[/tex]
Hence, 175 miles per 5 gallons = 46200 feet per quart.
Answer:
175 miles per 5 gallons = 46200 feet per quart.
