Answer:
d =5
Step-by-step explanation:
d = [tex]\sqrt{(x2-x1)^2 + (y2-y1)^2}[/tex]
at (1,5), (5,2)
d= [tex]\sqrt{(5-1)^2 +(2-5)^2}[/tex]
[tex]d = \sqrt{16 + 9} \\d=\sqrt{25}\\ d =5[/tex]
Therefore 5 is the distance.
Answer:
C
Step-by-step explanation:
calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (1, 5 ) and (x₂, y₂ ) = (5, 2 )
d = [tex]\sqrt{(5-1)^2+(2-5)^2}[/tex]
= [tex]\sqrt{4^2+(-3)^2}[/tex]
= [tex]\sqrt{16+9}[/tex]
= [tex]\sqrt{25}[/tex]
= 5

Sum of integers from -10 to 50
Answer:
1220
Step-by-step explanation:
This can easily be done as follows,
Take the first term of the series, (a = -10)
Take the last term of the series, (l = 50)
The numbers of terms is n = 50+10+1 = 61
Now,
For sum,
S= n/2 (a+l) =60/2 (50+-10) = 61/2 (50-10) = 61/2*40 = 1220

Jerry ran 4/3 of a mile in 4/18 of an hour. What was Jerry's rate of speed?
⚫️4 miles per hour
⚫️6 miles per hour
⚫️5_1/3 miles per hour
⚫️8/27 miles per hour
Answer:
B, 6 miles per hour
Step-by-step explanation:
1. 4/3 of a mile in 4/18 of an hour, rewrite as (4/3 / 4/18)
2. Dividing fractions is multiplying by the reciprocal, so (4/3 * 18/4)
3. (4/3 * 18/4 = 72/12)
4. 72/12 can be simplified to 6/1 or 6.
5. Answer is B, 6 miles per hour

What number line represents the solution to the inequality below

Answer:
The answer is 3 or x<3.
Finding the area of a triangle is straightforward if you know the length of the base and the height of the triangle. But is it possible to find the area of a triangle if you know only the coordinates of its vertices? In this task, you’ll find out. Consider ΔABC, whose vertices are A(2, 1), B(3, 3), and C(1, 6); let line segment AC represent the base of the triangle.
Part A
Find the equation of the line passing through B and perpendicular to AC .
Answer:
[tex]y : \frac{1}{5} x + \frac{12}{5}[/tex]
Step-by-step explanation:
the slope of the line AC :
[tex]\frac{6-1}{1-2} = \frac{5}{-1} =-5[/tex]
Let y : mx + p be the equation of the line D passing through B and perpendicular to AC.
Where m is the slope and p is the y value of the y intercept point.
The line D is perpendicular to AC means the product of their slopes is −1
Therefore
(−5) × m = −1
Then
[tex]m=\frac{-1}{-5} =\frac{1}{5}[/tex]
We obtain, the equation of D is :
[tex]y : \frac{1}{5} x + p[/tex]
At this point ,we still need the value of p to get the full equation of D.
B(3, 3)∈ D
[tex]3=\frac{1}{5} \left( 3\right) +p[/tex]
[tex]\Longleftrightarrow p=3-\frac{3}{5} =\frac{12}{5} =2.4[/tex]
thus , the equation of D is :
[tex]y : \frac{1}{5} x + \frac{12}{5}[/tex]
Yes it's possible through matrix
Let's find out the area formula for our vertices
That's
[tex]\\ \rm\Rrightarrow \left|\begin{array}{ccc}\rm 2&\rm 1&\rm 1\\ \rm 3&\rm 3&\rm 1\\ \rm 1&\rm 6&\rm 1\end{array}\right|[/tex]
The determinant values modulus is the area
Slope of AC
m=6-1/1-2=-5Perpendicular lines have slopes negative reciprocal to each other
Slope of line B to AC =1/5So

.A bicycle normally sells for $475. The bicycle was discounted 30% for a
sale. After the sale was over, the new price of the bicycle was 25%
higher than the sale price. What was the new price of the bicycle?
Answer:
415.63
Step-by-step explanation:
Multiply the price by the sales tax to find out how much money the sales tax will add.
Answer:
$415.63
Step-by-step explanation:
475
after 30%
475 times .30 = 142 5
475 - 142.5 = 332.5 <- sale price
332.5 times .25 = 83.125
332.5 + 83.125 = 415.625 <- new price

work out value of a
Answer:
a=99
Step-by-step explanation:
First, let's subtract 136 from 180. We get 44, which means that the angle of the other side is 44 degrees.
180-136=44
Next, let's subtract 125 from 180. 180-125 = 55. This means the other angle next to 125 degrees is 55 degrees.
180-125=55
We know that the sum of a triangle's angles is = 180 degrees
We can find the last angle of the triangle by adding 44 & 55, and then subtracting that sum from 180 (the total sum).
44+55=99
180-99=81
For our last and final step, let's subtract 81 from 180 to find the angle NEXT to 81 (a).
180-81=99
a = 99 degrees
