Worth 25 points help

Answer:

Step-by-step explanation:

Length (a) = 12-2x

Width (b) = 16-2x

Height (h) = x

Volume = a*b*h = x(12-2x)(16-2x) = 192x-56x^2+4x^3

Use derivative to find max.

dV/dx = 192-112x+12x^2 = 0

x = 7.07, 2.26

You can use second  derivative or take two closest points and find gradient of them to find max x.

Max(x) = 2.26

Step-by-step explanation:

sum the parts of the ratio, 1 + 2 + 3 = 6 parts

Divide 180° ( sum of angles in a triangle ) by 6

180° ÷ 6 = 30° ← value of 1 part of the ratio , then

2 parts = 2 × 30° = 60°

3 parts = 3 × 30° = 90°

The angles in the triangle are 30°, 60°, 90°

Then the triangle is right angled

Answer:

Step-by-step explanation:

Let missing angles be [tex]x[/tex], [tex]2x[/tex].

As the triangle is right-angled triangle.

[tex]x + 2x + {90}^{o} = {180}^{o} [/tex]

[tex]3x = {180}^{o} - {90}^{o} [/tex]

[tex]3x = {90}^{o} [/tex]

[tex]x = {30}^{o} [/tex]

[tex]2x = 30 \times 2 \\ = {60 }^{o} [/tex]

Answer:

Mean - 89

Median - 90.5

Mode - 89 or 92

Q1 - 84.5

Q3 - 96.5

IQR - 12

Step-by-step explanation:

A mean is an average. Just add all numbers then divide by how many numbers there are.

A median is a middle. Just arrange the numbers from smallest to largest and locate the middle value.

A mode is the number that appears most often. Count how many of each number there is.

Q1 is the middle of the lower half of the data.

Q3 is the middle of the upper half of the data.

IQR is the difference between Q3 and Q1. (subtract)

Answer:

A) -25 feet per second

Step-by-step explanation:

The average rate of change [2.5, 4 ]

[tex]=f(4)-+(2.5)/4-2.5[/tex]

[tex]f(4)=60 ft[/tex]

[tex]f(2.5)=97.5 ft[/tex]

[tex]4-2.5=1.5 sc[/tex]

[tex]Answer:-\frac{60-97.5}{1.5}[/tex]

[tex]= -25[/tex]

So option A is your answer

[tex]--------------[/tex]

Answer:

she travels H/3 miles in 1 hour.

Step-by-step explanation:

Heather drove at a constant rate she traveled 162 miles in 3 hours how far did Heather travel in 1 hour

suppose that Heather drove H miles in 3 hours. Then her constant rate (speed) was H/3. That's H/3 mph. So, she travels H/3 miles in 1 hour.

Answer:

To the nearest tenth of a percent, the approximate equivalent monthly depreciation rate is 1.0%

Step-by-step explanation:

From the question, we have a per annum decrease of 12.4%

what this mean is that, yearly, we expect a decrease of 12.4%

To get the monthly decrease value, we have to divide this given value by the number of months in a year which is 12

Thus, we have it that;

12.4%/12

= 1.0%

To the nearest tenth, the monthly decrease percentage is 1.0%

Answer:

[tex] \huge{\boxed{\mathfrak{Answer\hookleftarrow}}}[/tex]

Length = 6 cm

Width = 4 cm

Area = ?

Area of a rectangle = length (l) × width (w)

Area = 6 × 4

Area = 24 cm²

→ The area of the rectangle is 24 cm².

Answer:

equation: 28 = 2h+ h + h or you could say 28 = 4h

h= 7

Step-by-step explanation:

since both lines are the same length they equal each other.

to get h = 7 you have to solve the equation you made.

28 = 4h

28/4 = 4h/4

7 = h
