Step-by-step explanation:

We use (BODMAS) :

Brackets

Order/Index

Division

Multiplication

Addition

Subtraction

15 + 3 × 2

We do multiplication before addition :

3 × 2 = 6

15 + 6 = 21

100 points need answer asap!! The diameter of Circle Q terminates on the circumference of the circle at (3,0) and (-4,0). Write
Colt1911 [192]

Answer:

4(x+0.5)^2+4y^2=49

Step-by-step explanation:

Since the diameter of Circle Q terminates on the circumference of the circle at (3,0) and (-4,0), the diameter lies on the x-axis.

The midpoint of the ends of the diameter gives the center of the circle.

(\frac{3+-4}{2},\frac{0+0}{2}  =(\frac{-1}{2},\frac{0}{2})=(-0.5,0)

The radius of this circle is the distance from the center to one of this points on the circumference.

r=|3-0.5|=3.5

The equation of the circle is given by (x-a)^2+(x-b)^2=r^2

where (a,b)=(-0.5,0) is the center and r=3.5

We substitute to get:

(x--0.5)^2+(y-0)^2=3.5^2

The standard form equation is 4(x+0.5)^2+4y^2=49

A 4.00-kg box sits atop a 10.0-kg box on a horizontal table. The coefficient of kinetic friction between the two boxes and betwe
mamaluj [8]
Newton’s second law for the system of two boxes in the x-direction is given by: 
F - f k = (m + M )a
F - µk (m + M )g = (m + M )a
⇒ a = (F/m + M) - µkg = (150N / (4kg+10kg)) - 0.6(9.8m/s² ) = 4.83m/s²

For the top box, we get fs = ma = 4kg x 4.83m/s² =19.3N

Which of the point-slope equations below are correct for the line that passes through points (-2, -2) and (2, 1)?
Ne4ueva [31]
Find slope first:
m =y2-y1/x2-x1
m = 1--2/2--2
m = 3/4

Select a point, insert your slope, & put it into point slope form:
y-y1 =m(x-x1)

Your final answers are:

y-1=3/4(x-2)
OR
y+2 =3/4(x+2)

Write the coordinates of the vertices of a triangle A'B'C' that results from a translation of triangle ABC two units to the righ
gayaneshka [121]

Answer:

A'(4,-6) , B'(0,1), C'(-2,-2)

Step-by-step explanation:

From the given graph the coordinates of ΔABC area A (2,-2), B(-2,5) and C(-4,2)

If a translation is applied on ΔABC two units to the right and four units down  to create ΔA'B'C'.

Then to find the coordinates of ΔA'B'C' will be we need to apply the translation rule

(x,y)\rightarrow(x+2,y-4)

Now, A(2,-2)\rightarrow A'(2+2,-2-4)=A'(4,-6)

B(-2,5)\rightarrow B'(-2+2,5-4)=B'(0,1)

and C(-4,2)\rightarrow C'(-4+2,2-4)=C'(-2,-2)
