Answers
Answer:
5 units
Step-by-step explanation:
By distance formula:
[tex]r = \sqrt{(4 - 1) ^{2} + {(7 - 3)}^{2} } \\ \\ r = \sqrt{ {3}^{2} + {4}^{2} } \\ \\ r = \sqrt{9 + 16} \\ \\ r = \sqrt{25} \\ \\ r = 5[/tex]
Answer:
radius = 5 units
Step-by-step explanation:
The radius is the distance from the centre to a point on the circle.
Calculate r using the distance formula
r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (4, 7)
r = [tex]\sqrt{(4-1)^2+(7-3)^2}[/tex]
= [tex]\sqrt{3^2+4^2}[/tex]
= [tex]\sqrt{9+16}[/tex]
= [tex]\sqrt{25}[/tex]
= 5

Answers
Answer:
Resultados están más abajo.
Step-by-step explanation:
Dada la siguiente información:
Costo total= $1,956
Para calculate el valor parcial, debemos usar la siguiente información:
Precio proporcional= costo total* ( 1 - porcentaje de descuento)
50%:
Precio proporcional= 1,956*(1 - 0.5)
Precio proporcional= $978
25%:
Precio proporcional= 1,956*(1 - 0.75)
Precio proporcional= $489
Rob's first four test scores are 80, 85, 100 and 85. What does he have to score on the last test in order to have a test average of 90?
Answers
Answer:
100
Step-by-step explanation:
85 +80+100+85+x(the unknown),/the number of numbers ie 5
350+x/5=90
350+x=90 * 5
350+x=450
x=450-350
x=100
The score on the last test in order to have a test average of 90 is 100.
Given that, Rob's first four test scores are 80, 85, 100 and 85.
We need to find the score on the last test in order to have a test average of 90.
What is an average?By definition, an average is the arithmetic mean of the sum of all the values divided by the total number of values in a given set. An average is calculated for those sets of values which are more or less the same. The term average describes the numeric value that represents a large amount of data. An average can be derived by calculating the ratio of the sum of all the values to the number of units or values.
Let the score on the last test be x.
Now, average=(80+85+100+85+x)/5 =90
⇒350+x=450
⇒x=100
Therefore, the score on the last test in order to have a test average of 90 is 100.

16*8.5*10.5
Answer:
786.5
Step-by-step explanation:
16 x 10.5 = 168 x 2 = 336. 16 x 8.5 = 136 x 2 = 272. 8.5 x 10.5 = 89.25 x 2 = 178.5. 336 + 272 + 178.5 = 786.5
Write an equation of the line and interpret the slope.
Answers
Answer:
y=-100x+700
Step-by-step explanation:
Slope=Rise/Run=Δy/Δx=(y₂-y1)/(x₂-x₁)=(200-600)/(5-1)=(-400)/(4)=-100
So your slope would be m=-100
To find b, the y-intercept, we plug in a given output of y for a given input of x and solve for b:
y=mx+b (Slope-intercept form)
y=-100x+b (Equation so far)
200=-100(5)+b [Plugging in (5,200)]
200=-500+b
700=b
So since the y-intercept is b=700, then the equation of the line is y=-100x+700
