write an equation of a line perpendicular to the line 1/2x - 5 , passing through the point (-1 , 7)
y=-2x+5
Calculations ↓First of all we need to determine the slope of the line perpendicular to y = 1/2x - 5 .
The slopes of perpendicular lines are opposite reciprocals.
So we take 1/2 , turn it over , and change it's sign :
[tex]^1/_2\:\:\:--- > ^2/_1\:\:\:--- > 2\:\:\:--- > -2[/tex]
The slope of the line perpendicular to y = 1/2x-5 is -2 .
Since we're also given a point that the line crosses , we can write the line's equation in point - slope form :
y-y₁=m(x-x₁)
y-7=-2(x-(-1)
y-7=-2(x+1)
Now convert to slope intercept :
y-7=-2x-2
add 7 on both sides :
y = -2x+5[tex]\footnotesize\text{hope\:helpful}[/tex]

A password contains exactly 7 letters. How many passwords are possible if letters cannot be used more than once?
A. 8,031,810,176
B. 3,315,312,000
C. 823,543
D.657,800
Answer:
B
Step-by-step explanation:
This is a combination problem. For the first letter, there are 26 possible letters in the alphabet to use. For the second, we cannot use the letter used in the first, so there are only 25 possible letters. Repeat this for the remaining 5 letters.
1st - 26
2nd - 25
3rd - 24
4th - 23
5th - 22
6th - 21
7th - 20
To find the number of possible passwords, simply multiply all these numbers together. 26*25*24*23*22*21*20 = 3,315,312,000. Therefore B is the correct answer.
Answer:

the population of rats in nyc is estimated to be 3000000 currently. the rat population is growing by 1% per month. what is the estimated population of rats in 5 years?
Answer:
5,450,000
Step-by-step explanation:
The population can be modeled by an exponential function with a growth rate of 1% per month. The time of interest, 5 years, is 60 months.
__
population = (initial value) × (1 + growth rate per month)^(months)
p = 3,000,000 × (1.01^60) . . . . . . population in 60 months
p ≈ 5,450,000 . . . . in 5 years
The estimated population of rats in nyc is about 5,450,000 in 5 years.

funar in her famous cookie recipe.
Answer:
203.67
Step-by-step explanation:
all those numbers are confusing, but this is what i get from the picture
triangle area formula = 1/2 base * height
rectangle area formula = L * W
AB = 1/2 base * height, = 1/2 * 9 * 4, = 18
ab is the same as AB =18
C = 8.1 * 4.5 = 36.45
D = 8.1 * 7.2 = 58.32
E = 8.1 * 9 = 72.9
added together = 203.67

Round 0.293263 to the ten thousandths place
Answer:
0.293263 rounded to the ten thousandths place
=0.2933
Answer:
0.2933
Step-by-step explanation:
0.293263 is the decimal you have to round.
0.293263 (the first 2 is in the tenths place)
0.293263 (the 9 is in the hundredths place)
0.293263 (the first 3 is in the thousandths place)
0.293263 (the second 2 is in the ten-thousandths place)
0.293263 (the 6 is in the hundred-thousandths place)
0.293263 (the second 3 is in the millionths place)
They tell you to round the decimal to the ten thousandths place.
The second 2 is in the ten-thousandth place (0.293263).
To round digits you look at the number to its right, if it is 5-9 you round the number up, if it is 0-9 you leave the number as it is.
The number to the right of the number we're rounding (the 2 in the ten-thousands place) is a 6, 6 is a 5-9 number so we round the ten-thousands place digit up 1 number, (from 2 to 3).
And we have our rounded number 0.2933

The size of the angle QUP in the system formed by the equilateral triangle QUR, the equilateral triangle PUT and the square RUTS is equal to 150°.
How to determine a missing angle within a geometrical system
By Euclidean geometry we know that squares are quadrilaterals with four sides of equal length and four right angles and triangles are equilateral when its three sides have equal length and three angles with a measure of 60°. In addition, a complete revolution has a measure of 360°.
Finally, we must solve the following equation for the angle QUP:
m∠QUR + m∠QUP + m∠PUT + m∠RUT = 360
60 + m∠QUP + 60 + 90 = 360
m∠QUP + 210 = 360
m∠QUP = 150

f − 6
There may be 1 or 2 solutions.
f =
or f =
Answer:
3
Step-by-step explanation:
4f-3 = 5f-6
First I would try to get the f's on one side and the other numbers on the other, to do this you woudl have to add 6 to both sides
4f -3 = 5f -6
+6 +6
Making it into: 4f + 3 = 5f
Now to get the 4f on the other side we will have to subtract it from both sides
4f +3 = 5f
-4f -4f
3= f (Remember you do not have to put the 1, making 3 your answer)

Find the volume of the cone shown as a decimal rounded to the tenth. 22m 12m
Answer:
b
Step-by-step explanation:
the volume (V) of a cone is calculated as
V = [tex]\frac{1}{3}[/tex]πr²h ( r is the radius , h is the height )
here diameter = 12 , so r = 12 ÷ 2 = 6 and h = 22 , then
V = [tex]\frac{1}{3}[/tex]π × 6² × 22
= [tex]\frac{1}{3}[/tex]π × 36 × 22
= [tex]\frac{1}{3}[/tex]π × 792 ( cancel 3 and 792 by 3 )
= π × 264
