The answer for this is A because the longest pencil is going to be 9 cm as it says in the description. Since it says longest you aren’t talking. Area or volume, just the length and 9cm is the only question that will fit, so it’s A

I need this answered, please and thanks

Answer:

P = \frac{28\sqrt{2} }{2} units

A = 24.5 unit^{2}

Step-by-step explanation:

Length of one side

sin 45^{o} = \frac{x}{7}

7sin 45^{o}= x

7(\frac{\sqrt{2} }{2})= x

\frac{7\sqrt{2} }{2} = x

Perimeter = 4(\frac{7\sqrt{2} }{2}) = \frac{28\sqrt{2} }{2}

Area = (\frac{7\sqrt{2} }{2})(\frac{7\sqrt{2} }{2}) = \frac{98}{4} =24.5

Which of the following equations contains the point (8,5) and is perpendicular to the line y=2x-3
Snezhnost [94]

Answer:

y = - \frac{1}{2} x + 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x - 3 ← is in slope- intercept form

with slope m = 2

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{2}, thus

y = - \frac{1}{2} x + c ← is the partial equation

To find c substitute (8, 5) into the partial equation

5 = - 4 + c ⇒ c = 5 + 4 = 9

y = - \frac{1}{2} x + 9 ← equation of line

d1i1m1o1n [39]
This is a sum that needs understanding the starting and the ending number first. then you should understand that between the starting and the ending number there has to be pairs of numbers with a difference of 0.75.
The numbers are:
10.75, 11.50, 12.25, 13.00, 13.75, 14.50.
