q= -1
write an equation parallel to y=-3x-1 and passing through the point (4,-8)
Answer:
y = -3x + 4
Step-by-step explanation:
y = -3x - 1
a parallel line is going to look identical to the previous equation except for the last number.
for example,
y = -3x + 10
and
y = -3x - 2
are both parallel lines
now, substitute y and x for the points of the coordinate given.
y = -3x - 1
-8 = -3*4 - 1
-8 = -12 - 1
this equation isn't true.
so change the last number to make it true
-8 = -12 + 4
-8 = -8
so, your new equation is
y = -3x + 4

The electron and proton of a hydrogen atom are separated, on average, by a distance of about 5.3 x 10^-11 meters. Find the magnitudes of the electric force and the gravitational force that each particle exerts on the other.
And pls show work of how you did it :)
Answer:
Electric force = 8.20x10⁻⁸ N
Gravitational force = 3.61x10⁻⁴⁷ N
Step-by-step explanation:
1. The electric force can be found using the following equation:
[tex] F_{e} = \frac{Kq_{e}q_{p}}{d^{2}} [/tex]
Where:
K: is the Coulomb's constant = 9x10⁹ N.m²/C²
[tex]q_{p}[/tex]: is the charge of the proton = 1.6x10⁻¹⁹ C
[tex]q_{e}[/tex]: is the charge of the electron = -1.6x10⁻¹⁹ C
d: is the distance = 5.3x10⁻¹¹ m
Hence, the magnitude of the electric force is:
[tex] |F_{e}| = \frac{9\cdot 10^{9} N.m^{2}/C^{2}*(-1.6\cdot 10^{-19} C)*1.6 \cdot 10^{-19} C}{(5.3 \cdot 10^{-11} m)^{2}} = 8.20 \cdot 10^{-8} N [/tex]
2. The gravitational force can be calculated as follows:
[tex] F_{g} = \frac{Gm_{e}m_{p}}{d^{2}} [/tex]
Where:
[tex]m_{e}[/tex]: is the electron's mass = 9.1x10⁻³¹ kg
[tex]m_{p}[/tex]: is the proton's mass = 1.67x10⁻²⁷ kg
G: is the gravitational constant = 6.67x10⁻¹¹ N.m²/kg²
Therefore, the gravitational force is:
[tex] F_{g} = \frac{6.67 \cdot 10^{-11} N.m^{2}/kg^{2}*9.1 \cdot 10^{-31} kg*1.67 \cdot 10^{-27} kg}{(5.3 \cdot 10^{-11} m)^{2}} = 3.61 \cdot 10^{-47} N [/tex]
As we can see, the gravitational force is much less than the electric force.

Item 14 The endpoints of $\overline{AB}$ are $A\left(7,\ 8\right)$ and $B\left(-2,\ 3\right)$ . Find the coordinates of the midpoint M. Coordinates of midpoint M: ( , )
Answer:
(2.5, 5.5)
Step-by-step explanation:
The formula for calculating the midpoint of two coordinates is expressed as;
M(X, Y) = {(x1+x2/2, y1+y2/2)}
X = x1+x2/2
Y = y1+y2/2
Given the coordinates (7, 8) and (-2, 3)
X = 7-2/2
X = 5/2
X = 2.5
Y = y1 + y2/2
Y = 8+3/2
Y = 11/2
Y = 5.5
Hence the midpoint M of the coordinates is (2.5, 5.5)

Answer:
(x-8)(x+7) in which x = 8, -7 (if needed)
Step-by-step explanation:
Figure out first what two numbers can go to 56. The possible combinations are 1 and 56, 2 and 28, 4 and 14, and 7 and 8. The middle number has to equal the sum of -1. Therefore, 7 and 8 will go to that sum with -8 as one and +7 as another. Your factor should be (x - 8) (x + 7) and when you are finding for the x-values, it should be 8 and -7 when necessary.

(g+2)^5
Step-by-step explanation:
We need to use the binomial theorem/Pascal's triangle here.
(a+b)^5 = (5 choose 0)a^5 + (5 choose 1)a^4*b + (5 choose 2)a^3*b^2 + (5 choose 3)a^2*b^3 + (5 choose 4)a*b^4 + (5 choose 5)b^5.
5 choose 0 = 1
5 choose 1 = 5
5 choose 2 = 10
5 choose 3 = 10
5 choose 4 = 5
5 choose 5 = 1
And 1, 5, 10, 10, 5, 1, is the (5+1) = 6th row of pascal's triangle.
Therefore we get
g^5 + 5g^4*2 + 10g^3*2^2 + 10g^2*2^3 + 5g*2^4 + 2^5
which is
g^4 + 10g^4 + 40g^3 + 80g^2 + 80g + 32
Or, you could do the slow way, by just doing (g+2)(g+2)(g+2)(g+2)(g+2)

It takes 1 hr for cell A to complete a cell cycle and produce two cells.The cell cycle of cell Brakes 2 hrs.How many more cells would be formed from cell A than from cell B in 6 hrs
Answer:
6 cells
Step-by-step explanation:
Cell A = 1 hour to complete cycle and produce 2 cells
Number of cycles completed on 6 hours = 6 cycles
Number of cell produced = 2 * number of completed cycles = 2 * 6 = 12 cells
Cell B = 2 hours to complete a cycle ; 2 cells produced per cycle
Number of cells produced after 6 hours :
Number of cycles in 6 hours = 6/2 = 3 cycles
Number of cells produced = 3 * 2 = 6 cells
Difference in cells produced : (12 - 6) = 6 cells

Solve for x: x ÷ 7 = 16
Answer:
x=112
Step-by-step explanation:
[tex]\frac{x}{7} =16[/tex]
x=16*7
x=112
Answer: x = 112
Step-by-step explanation: To solve this equation for x,
I would first change x ÷ 7 to x/7 to make it easier to visualize.
So we have [tex]\frac{x}{7} = 16[/tex].
Since x is being divided by 7, we multiply both sides by 7.
On the left, hat gives us x and on the right, 16 x 7 is 112.
So we have x = 112.
A Pyramid is placed inside a prism as shown in the pyramid has the same base area B as a prison but half the height H of the prism which expression gives the volume of the pyramid
Answer:
D) V= 1/6 bh
Step-by-step explanation:
The expression that provides the volume of the pyramid is as follows;
As mentioned in the question
It is given that the pyramid put inside a prism
Also the pyramid contains the similar base area but the height is half of the prism
so the base area of the pyramid is b
And, the Height of the pyramid = h ÷ 2
Now as we know that
The volume of the pyramid is
V = 1 ÷3 × base ares × height
= 1 ÷ 3 × b × h ÷ 2
V = 1 ÷ 6 bh
So, the volume is 1 ÷6 bh cube unit.
Answer:
V = 1/6 BH
Step-by-step explanation:
the volume of a pyramid is 1/3 BH , since the pyramid is only half the height of the prism you'll have to multiply 1/3 x 2 = 1/6
