5. (10.607, 14.229)
6. (-1.586, -0.764)
7. (4, 5.211)
8. (-3.5, -2.342)
Step-by-step explanation:
Given:
the attached function definitions and intervals
Find:
the minimum and maximum on the given interval
Solution:
In a couple of cases, the coefficient of x is negative, indicating the basic square root function has been reflected over the y-axis. That will put the maximum at the left end of the interval, instead of the right end, where it would otherwise be.
__
5. minimum: f(3.5) = 5√(3.5+1) +1 = 5√4.5 +1 = 10.607
maximum: f(6) = 5√(6+1) +1 = 5√7 +1 = 14.229
__
6. minimum = f(-2) = √(-(-2)) -3 = √2 -3 = -1.586
maximum = f(-5) = √(-(-5)) -3 = √5 -3 = -0.764
__
7. minimum = f(-6) = 2√(3 -(-6)) -2 = 2√9 -2 = 4
maximum = f(-10) = 2√(3 -(-10)) -2 = 2√13 -2 = 5.211
__
8. minimum = f(0) = (1/2)√(0 +1) -4 = -3.5
maximum = f(10) = (1/2)√(10+1) -4 = (1/2)√11 -4 = -2.342

Andy painted at his house. He used 1/4 of his paint to paint five walls. What fraction of his paint did andy use on each wall if he used the same amount of paint on each?
Answer:
1/20
Step-by-step explanation:
1/4 ÷ 5
1/4 x 1/5
1/20
Hey there!
The answer to your question is [tex]\frac{1}{20}[/tex]
To solve this we must divide [tex]\frac{1}{4}[/tex] by [tex]5[/tex].
To do this, we can multiply [tex]\frac{1}{4}[/tex] by the reciprocal of [tex]5[/tex], or [tex]\frac{1}{5}[/tex].
[tex]\frac{1}{4} * \frac{1}{5}[/tex]
[tex]\frac{1}{20}[/tex]
Therefore, Andy used [tex]\frac{1}{20}[/tex] of a can of paint on each wall of his house.
Hope it helps, have a great day, and stay safe! You've got this!

Answer:
Function A's slope>Function B
Step-by-step explanation:
So first we see that the y-intercept of function A is 2 (we see (0,2) as a point on the graph) and we know that it's linear. So this leaves us with
mx+2=y.
Now we can just plug in to solve for m!
m+2=6
(Subtract 2 from both sides)
m=4
So the slope of function A is 4.
Next we move onto function B.
We can clearly see that the function is decreasing, meaning that function A's slope is greater.
Find the volume of the composite solid.
Answer:
768 m^2
Step-by-step explanation:
Separate the shapes
We can first separate the triangular pyramid from the rectangular prism.
We can calculate them separately.
Calculate
The volume of the triangular pyramid is the base multiplied by the height divided by 3. The base of the pyramid has the same base as the prism so:
8 * 8 = 64
Then we need the height which is 6 so:
64 * 6/3 = 64 * 2 = 128 m^2
Then we calculate the volum of the prism; the formula for that side times side time side:
8 * 8 * 10 = 640 m^2
The total volume is them added up:
128 + 640 = 768 m^2
simplify the expression (2h+1)(8)
Answer:
[tex]16h+8[/tex]
Step-by-step explanation:
[tex](2h+1)(8)[/tex]
Multiply 8 with 2h and 1
[tex]16h+8[/tex]
Consider the Parallelogram
If the perimeter of the parallelogram is 60, what is the length of HG?
Answer:
The length of HG = 11 units
Step-by-step explanation:
We know that opposite sides of a parallelogram are equal.
so
EF = GHand
FG = EHGiven that
FG = 2x+5
so
EH = 2x+5
also
EF = 3x-10
so
GH = 3x-10
Given that the Perimeter of a parallelogram = 60
As the perimeter of a parallelogram is the sum of all the sides, so
FG + EH + EF + FH = 60
substituting FG = 2x+5, EH = 2x+5, EF = 3x-10, GH = 3x-10
(2x+5) + (2x+5) + (3x-10) + (3x-10) = 60
remove parenthese
2x+5 + 2x+5 + 3x-10 + 3x-10 = 60
group similar elements
2x + 2x + 3x + 3x + 5 + 5 - 10 - 10 = 60
10x - 10 = 60
10x = 60+10
10x = 70
divide both sides by 10
10x/10 = 70/10
x = 7
Therefore, the value of x = 7
Thus,
The length of HG = 3x-10 = 3(7) - 10 = 21 - 10 = 11 units
Hence,
The length of HG = 11 units
Name the relationship
A.complementary
B.linear pair
C.vertical
D.adjacent
Answer:
∠a and ∠b are the adjacent angles.
Therefore, option D i.e. adjacent is the correct option.
Step-by-step explanation:
Given the angles
∠a∠bWe know that the two angles are termed as the adjacent angles when they share the:
common vertexcommon sideFrom the given diagram, we are given the angles ∠a and ∠b.
It is clear that angles ∠a and ∠b have a common vertex and common side.
Therefore, the relationship between the angles ∠a and ∠b is 'adjacent'.
In other words, ∠a and ∠b are the adjacent angles.
Please note that the given relation can not be a 'linear pair' because the sum of two angles is NOT a straight line or 180°.
Therefore, option D i.e. adjacent is the correct option.
Consider the function f(x) = 3x and a translation of f(x) named g(x). Janeen created a table for select values of x. Her table is shown below.
A 3-column table has 4 rows. Column 1 is labeled x with entries 0, 1, 2, 3. Column 2 is labeled f (x) with entries 1, 3, 9, 27. Column 3 is labeled g (x) with entries 3, 9, 27, 81.
What can be concluded about the relationship between the two functions? Check all that apply.
The functions have the same base.
The functions have the same range.
The functions have the same exponent.
The functions have the same domain.
g(x) is a translation left 1 unit.
g(x) is a translation right 2 units.
g(x) is a translation up 2 units.

Mrs. Canale’s class is selling frozen pizzas to earn money for a field trip. For every pizza sold, the class makes $5.35 They have already earned $182.90 but they need $750 How many more pizzas must they sell to earn $750? Write and solve an equation for this scenario. If you can, can you show the equation you used.
Answer:
106 pizzas
Step-by-step explanation:
The number of more pizzas required to sell for earning $750 is as follows:
Given that
Already earned amount = $182.90 =x
Need to achieved = $750 = y
So, the remaining amount would be
= y - x
= $750 - $182.90
= $567.10
For every pizza sold, it make for $5.35
So, the number of pizza would be
= $567.10 ÷ $5.35
= 106 pizzas
