Rewrite 27 as 3 ³.
(3³)[tex]\frac{1}{3}[/tex]
Apply the power rule and multiply exponents, [tex](a^{m})^{n} =a^{mn}[/tex]
3³([tex]\frac{1}{3}[/tex])
The simplified value of exponential expression27(1/3) is about equivalent to 3.
Here, we have,
give that,
the expression is 27^1/3.
We know,
An exponential expression is a mathematical expression that requires raising a variable to a power.
now, we get,
Rewrite 27 as 3 ³.
so, we have, (3³)^1/3
Apply the power rule and multiply exponents, nᵃᵇ= (nᵃ)ᵇ
3³^(1/3) = 3
i.e. we have,
(27)^1/3
= (3^3)^1/3
= 3
As 3*3*3 is 27 so we can write 3^3 ...both power got cancelled hence we got 3 as a answer.
Hence, The simplified value of exponential expression27(1/3) is about equivalent to 3.

What is the y-intercept of the quadratic function
f(x) = (x - 6)(x - 2)?
Answer:
y = 12 → (0|12)
Step-by-step explanation:
f(x) = (x - 6)(x - 2)
y = (x - 6)(x - 2)
y = x² - 6x - 2x + 12
y = x² - 8x + 12
y = 0² - 8*0 +12
y = 12

Given B(17,5), C(11, -3), D-1, 2), and
E(x, -6), find the value of x so that BC || DE.
Answer:
[tex]x=-7[/tex]
Step-by-step explanation:
Remember that:
Two lines are parallel if their slopes are the same.Two lines are perpendicular if their slopes are negative reciprocals.And two lines are neither (a.k.a intersecting) if they are neither parallel nor perpendicular.We want to find the value of x such that [tex]\overline{BC}\parallel\overline{DE}[/tex].
Therefore, the slopes of BC and DE must be equivalent.
So, let's find the slope of BC first.
BC)
We can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let B(17, 5) be (x₁, y₁) and let C(11, -3) be (x₂, y₂). Substitute:
[tex]\displaystyle m=\frac{-3-5}{11-17}[/tex]
Subtract:
[tex]m=-8/-6=4/3[/tex]
So, the slope of BC is 4/3.
DE)
Let D(-1, 2) be (x₁, y₁) and let E(x, -6) be (x, y₂). Substitute:
[tex]\displaystyle m=\frac{-6-2}{x-(-1)}[/tex]
We know that the two slopes must be equal. So, the slope of DE must also be 4/3. Substitute 4/3 for m:
[tex]\displaystyle \frac{4}{3}=\frac{-6-2}{x-(-1)}[/tex]
Solve for x. Simplify the right:
[tex]\displaystyle \frac{4}{3}=\frac{-8}{x+1}[/tex]
Cross multiply:
[tex]4(x+1)=-8(3)[/tex]
Multiply on the right:
[tex]4(x+1)=-24[/tex]
Divide both sides by 4:
[tex]x+1=-6[/tex]
Subtract 1 from both sides:
[tex]x=-7[/tex]
So, the value of x is -7.
And we're done!

Answer: C
Step-by-step explanation:
To adopt a dog from an animal shelter, you must pay $80 for vaccinations, $65 to spay or neuter the dog, and $50 for a wellness exam by a veterinarian.
a. Write an expression in simplest form that represents the amount (in dollars) it costs to adopt x dogs.
An expression is (?) dollars.
The equation with (x) in dogs and (y) in dollars is [tex]y=195x[/tex]
First, you must set up your equation.
[tex]y=80x+65x+50x[/tex]
Then, you must add like terms to simplify the equation
[tex]y=195x[/tex]
Answer:y=195x
Step-by-step explanation:
Which of the equations below will answer the following question? Select all that apply. Explain your answers.
I think of a number, add 7 and then multiply by 4. My answer is 80. What was my number?
x + 28 = 80
4(x+7) = 80
4x + 7 = 80
4x + 28 = 80
Is the line through points p (3,-5) and Q(1,4)parallel to the line through points R( -1,1) and S (3,-3)
Answer:
No
Step-by-step explanation:
To find out if the lines that go through the pairs of points are parallel, we must find the slope of each line. If the slopes are equivalent, then they are parallel. If not, then they are not parallel.
We can use the slope formula to find the slope between two points. The slope formula is:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope between the points (x₁, y₁) and (x₂, y₂).
Lets first find the slope between points P and Q.
[tex]m=\frac{-5-4}{3-1}=\frac{-9}{2}=-4.5[/tex]
So the slope between P and Q is -4.5.
Now lets find the slope between the points R and S.
[tex]m=\frac{-3-1}{3-(-1)}=\frac{-4}{4}=-1[/tex]
So the slope between R and S is -1.
Since -4.5 does not equal -1, the lines are not parallel.

Solve... 4x + 30 = -6(x - 2)
I got -4.2 but it's wrong!
Answer: x= -9/5 or x = -1.8
Step-by-step explanation:
4x + 30 = -6(x - 2) First apply the distributive property on the left side
4x + 30 = -6x + 12 Add 6x to both sides
+6x +6x
10x + 30 = 12 Subtract 30 from both sides
-30 -30
10x = -18 Divide both sides by 10
x = -9/5 or x = -1.8
Answer:
the answer is -1.8 if you want to use the decimal and -9/5 if you want to use the fraction
Step-by-step explanation:
4x + 30 = -6(x - 2)
4x+30 = -6x + 12
4x + 6x = 12 - 30
10x = -18
divide both side by 10
x = -9/5 or -1 4/5 or -1.8

Kristen has been waiting all summer for her family's annual road trip. This year, they're headed to Yellowstone National Park. Kristen just saw a sign that said the park is 10 miles away, so the drive is almost over. If Kristen's father drives 50 miles per hour, how many more minutes will it take to reach the park?
Answer: It will take 12 minutes to the reach the park.
Step-by-step explanation:
We know that, [tex]\text{Speed }=\dfrac{\text{distance}}{\text{time}}[/tex]
[tex]\Rightarrow\ \text{Time}=\dfrac{\text{Distance}}{ \text{Speed}}[/tex]
Given: Speed = 50 miles per hour
Distance needs to travel = 10 miles
Now, Time required to reach the park = [tex]\dfrac{10}{50}=\dfrac{1}{5}\text{ hour}[/tex]
Since 1 hour = 60 minutes
So, [tex]\dfrac15\text{ hour}=\dfrac15\times 60=12\text{ minutes}[/tex]
Hence, it will take 12 minutes to the reach the park.
The graph represents the gallons of water in a water tank with respect to the number of hours since it was completely filled. The total capacity of the water tank is gallons, and the rate of change is gallons per hour.
Answer:
Total capacity of the water tank is 400 gallons
Rate of change in water level is 20 gallons per hour
Step-by-step explanation:
The graph attached represents the gallons of water in a water tank with respect to the number of hours since it was completely filled.
The total capacity of the water tank is represented by the y-intercept of the graph that is 400 gallons.
Now to calculate the rate of change in water level we will take two points on the given line and find the slope.
There are two points (0, 400) and (5, 300) on the line.
So the slope of the line is (400-300)/(0-5)= -100/5= -20
This minus notation of slope shows that level of water is reducing and rate of change in water level is 20 gallons per hour.

Find the value of the variable.
The required value of variable m is 15.
Gvien that,
A line segment AC is given, On which B is the midpoint,
AB = 3m + 5
and BC = 4m - 10
AB = BC
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
AC is the line segment where B is the midpoint on the line AC. So,
AC = AB + BC
AB = BC
3m + 5 = 4m - 10
m = 15
Thus, the required value of variable m is 15.

Tamara wants to calculate the height of a tree outside her home. Using her clinometer, she measures the angle from 35 feet away from the base of the tree and gets an angle of 62°. Tamara's eye level is 5.5 feet above the ground. How tall is the tree?
Answer:
71.32 feet
Step-by-step explanation:
We set up a trigonometric function to get height of tree
Distance ,x = 35 feet away from tree base
Angle = 62⁰ at eye level
Y = tan(angle) * x
= Y = tan(62⁰) x 35
Y = 1.881 x 35
Y = 65.82 feet
We add Tamara's height to the total height of the tree
= 65.82feet + 5.5 feet
= 71.32 feet is the height of the tree
