Which is closest to the length of diagonal
AC?
Answer:
A. 8 units
Step-by-step explanation:
Coordinates of A = (-2, -2)
Coordinates of C = (5, 2)
Use distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex] to calculate the length of diagonal [tex] \overline{AC} [/tex].
Let,
[tex] A(-2, -2) = (x_1, y_1) [/tex]
[tex] C(5, 2) = (x_2, y_2) [/tex]
[tex] d = \sqrt{(5 -(-2))^2 + (2 -(-2))^2} [/tex]
[tex] d = \sqrt{(7)^2 + (4)^2} [/tex]
[tex] d = \sqrt{49 + 16} = \sqrt{65} [/tex]
[tex] d = 8.1 [/tex] (nearest tenth)
Therefore, the closest to the length of diagonal [tex] \overline{AC} = 8 units [/tex]

Answer:
Step-by-step explanation:f(h(x))= 2x -21
f(x)= x^3 - 6
h(x)=\sqrt[3]{2x-15}
WE need to find f(h(x)), use composition of functions
Plug in h(x)
f(h(x))=f(\sqrt[3]{2x-15})
Now we plug in f(x) in f(x)
f(h(x))=f(\sqrt[3]{2x-15})=(\sqrt[3]{2x-15})^3 - 6
cube and cube root will get cancelled
f(h(x))= 2x-15 -6= 2 x-21

If a ship travels north for 18 miles and east for 12 miles,
to the nearest tenth, approximately how far away is it
from it's starting point?
Answer:
The ship is approximately 21.6 miles away from its starting point
Step-by-step explanation:
∵ The North and the East are perpendicular
→ That means the distance between the starting position and
the ending position shows a hypotenuse of a right triangle which
its legs are the distances due to North and East
∵ The ship travels north for 18 miles
∴ leg1 = 18 miles
∵ The ship travels east for 12 miles
∴ leg2 = 12 miles
→ By using Pythagoras Theorem
∵ (hypotenuse)² = (leg1)² + (leg2)²
∴ (hypotenuse)² = (18)² + (12)²
∴ (hypotenuse)² = 324 + 144
∴ (hypotenuse)² = 468
→ Take √ for both sides
∴ hypotenuse = 21.63330765
→ Approximate it to the nearest tenth
∴ hypotenuse = 21.6 miles
∵ The hypotenuse of the right triangle represents the distance from
the starting position to the ending position
∴ The ship is approximately 21.6 miles away from its starting point

The volume of a box (v) varies directly with its length (l) if one of the boxes has a volume of 325 cubic inches and a length of 13 inches what is the costant of proportionality for the group of boxes
Answer:
The constant of proportionality for the group of boxes is: 25
Step-by-step explanation:
Proportion means that change in one quantity causes change in other quantity. Direct variation means that increase in one quantity causes increase in the other quantity.
Let l be the length and v be the volume
Then according to given statement
V∝l
Removing the proportionality symbol introduces a constant in the equation
[tex]V = kl[/tex]
Putting V = 325 and l = 13
[tex]325 =k(13)\\k = \frac{325}{13}\\k = 25[/tex]
Hence,
The constant of proportionality for the group of boxes is: 25
Writing proportional equations Problem The Green Goober, a wildly unpopular superhero, mixes 333 liters of yellow paint with 555 liters of blue paint to make 888 liters of special green paint for his costume. Write an equation that relates yyy, the amount of yellow paint in liters, and bbb, the amount of blue paint in liters, needed to make the Green Goober's special green paint.
Answer:
The equation that relates the amount of yellow paint, y, and the amount of blue paint,b, in liters [tex]5y-3b=0[/tex].
Step-by-step explanation:
Given that The Green Goober mixes 333 liters of yellow paint with 555 liters of blue paint to make 888 liters of special green paint for his costume.
So,
The amount of yellow paint: the amount of blue paint [tex]= 333: 555[/tex]
If the amount of yellow paint is y and the amount of blue paint is b, then, from the above relation
[tex]y: b = 333: 555\Rightarrow \frac y b = \frac {333}{555} \\\\\Rightarrow \frac y b = \frac {3}{5} \\\\\Rightarrow 5y=3b \\\\\Rightarrow 5y-3b=0.[/tex]
Hence, the equation that relates the amount of yellow paint, y, and the amount of blue paint,b, in liters [tex]5y-3b=0[/tex].
Answer:
5y-3b=0

What is the minimum value of 6x + 8y in the feasible region?
(0, 4)
(6, 4)
(6, 0)
Answer:
(0,4)
Step-by-step explanation:
when you plug in 0 for x and 4 for y, you get
6(0) + 8(4)=32
when plugging in each set of ordered pairs, this set gives the lowest answer
Solve the equation.
–9x + 1 = –x + 17
x = –8
x = –2
x = 2
x = 8
-9x + 1= -x + 17
- 9x + x= 17 - 1
-8x = 16
- x = 16÷8
x = -2
Answer:
-9x + 1= -x + 17
- 9x + x= 17 - 1
-8x = 16
- x = 16÷8
x = -2

There are 2300 ways by which we can select 3 students out of 25 students.
What is Combination?Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements.
Here total number of Students = 25
Number of selection = 3
Now,
Total number of ways by which we can select 3 out of 25 = ²⁵C₃
= 25!/3!.22!
= 25 X 24 X 23 X 22! / 3X2X1 X 22!

a biker can ride a bicycle 18 miles in 3 hours. the messenger estimates that it will take 7 hours to bike 22 miles. here is the messengers work:
step 1: 22-18=4
step 2: 3+4=7
what mistake did the messenger make?
• the messenger did not make a mistake. the estimate is correct
• the 3 and 4 should have been multiplied instead of added.
• the messenger used addition and Subtraction instead of multiplication and division
• the 22 and 18 should have been divided instead of subtracted
• the 22 and 18 should have been averaged instead of subtracted
Answer:
The messenger should use addition and Subtraction instead of multiplication and division
Step-by-step explanation:
It is given that,
A biker can ride a bicycle 18 miles in 3 hours. the messenger estimates that it will take 7 hours to bike 22 miles.
He has done two steps :
step 1: 22-18=4
step 2: 3+4=7
The steps done by the biker are wrong. The correct step should be :
In 1 hour, he should cover (18/3) miles i.e. 6 miles
In 7 hours, he will cover (6×7) miles i.e. 42 miles
It means he should use addition and Subtraction instead of multiplication and division. Hence, the correct option is (c).

An unused roll of paper towels is shown. What is the volume of the unused role
Answer:
1310.4
Step-by-step explanation:
26 x 12= 312 x 4.2= 1310.4
The volume of the unused role is 821.34π cm³
What is the volume?Volume is defined as the space occupied within the boundaries of any three-dimensional solid.
Given that is a figure of unused roll of paper towels, we need to find the volume of the unused role,
The volume of a cylinder with radius r and height h is V = π·radius²·height
To find the same we will subtract the volume of the inner cylinder from the outer,
Volume = 6²π(26) - (2.1)²π(26)
= 26(36π - 4.41π)
= 26(31.59π)
= 821.34π cm³
Hence, the volume of the unused role is 821.34π cm³

The radius of a semi-circle measures 5
units. Find its area.
Answer:
≈39.27 units
Step-by-step explanation:
To find the area of a semi circle, you use the formula for finding the area of a circle, which is [tex]\pi[/tex][tex]r^{2}[/tex], and then you divide that by 2 since it is half of a circle.
In this case, [tex]\pi[/tex][tex](5)^{2}[/tex] ≈ 78.54
