Leah's rectangular driveway is 48 feet long and 14 feet wide. With sidewalk chalk, Leah drew a straight diagonal line on her driveway from one corner to the opposite corner.

How long is the diagonal line Leah drew?

25 feet

46 feet

50 feet

62 feet

Answers

[tex]48^2+14^2=x^2\\x^2=2500\\x=50[/tex]

The length of the diagonal drawn by Leah will be 50 feets

Given the Parameters :

Length = 48 feet Width = 14 feets

The length of the diagonal is the value of the hypotenus in a right angles triangle :

Let the length of the diagonal = d

d = √(length)² + (width)²

d = √48² + 16²

d = √2304 + 256

d = √2560

d = 50.5961 feets

Therefore, the closest value for the length of the diagonal in the options given is 50 feets

Use completing the square to rewrite the given function in vertex form. Determine whether the vertex is a maximum or minimum
value. Select the TWO correct answers.
y = x2 + 4x - 10
-
A)
The vertex form is y = (x - 6)2 + 2.
B)
The vertex form is y= 4x + 2)2 - 10.
C)
The vertex form is y = -(x - 2)2 - 6.
D)
The vertex is a minimum value at point (-6,2).
E)
The vertex is a maximum value at point (2.-6).

Answers

Answer:

Step-by-step explanation:

The equation as written doesn’t work. Are you sure it is y = x² + 4x - 10, and not

y = -x² + 4x - 10 ?

y = -(x² - 4x) - 10

y = -(x² - 4x + 2²) + 2² - 10

y = -(x-2)² - 6

the vertex is a maximum at (2,-6)

what is the volume of the rectangular prism

Answers

It is all the numbers multiplied together. 135

Answer:

[tex]\Huge\boxed{D.135 cm^3}[/tex]

Step-by-step explanation:

Hello There!

We can find the volume of the figure by using the formula for volume of a rectangular prism

[tex]V=lwh[/tex]

where l = length, w = width and h = height

we are given all of the dimensions so all we have to do is plug in the values

V = 3 x 9 x 5

3x9=27

27x5=135

so the volume of the rectangular prism is 135 cm³

What is fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given:

It takes an old printer 8 hours to print all the pictures for the yearbook.

A modern printer can do the same job in 5 hours.

If both work together,

it will take,

x(1/8 + 1/5) = 1

x(8 + 5)/40 = 1

8x + 5x = 40

x = 40/13

x = 3.07

x = approximately 3.1 hours.

Therefore, the work will be done in 40/13 hours.

"It is a mathematical statement of an order relationship (greater than, greater than or equal to, less than, or less than or equal to) between two numbers or mathematical expressions."

What is addition property of inequality?

" Let x, y, and z be real numbers.

If x > y, then x + z > y + z."

For given question,

t is a number between 6 and 9.

So, we have an inequality.

⇒ 6 < t < 9

By addition property of inequality,

⇒ 6 + 5 < t + 5 < 9 + 5

⇒ 11 < t + 5 < 14

Therefore, the number t + 5 is in between 11 and 14.
