Answer:
B, C, D and E are correct options
Step-by-step explanation:
Here, we want to get the correct options;
a. We simply divide the next term by the previous term so that we get the common ratio
That would be 16/-8 = -32/16 = -2
As we can see, the common ratio is -2 which means that the option cannot be correct
b. The 5th term is mathematically;
ar^4 = -8 * (-2)^4 = -8 * 16 = -128
This is correct
c. The 7th term is
ar^6 = -8 * (-2)^6 = -512
5th term is ar^4 = -8 * (-2)^4 = -128
So -512/-128 = 4
As we can see, this option is correct
d. 8th term is 1024
8th term is ar^7
= -8 * (-2)^7 = 1024 which is correct
e. 10th term is ar^9 = -8 * (-2)^9 = 4096
9th term is ar^8 = -8 * (-2)^8 = -2048
This is correct

B.) (y − 2) = 3(x − 1)
C.) (y − 1) = −3(x − 2)
D.) (y + 2) = 3(x + 1)
Please make sure the answer is correct
Answers
Answer:
B
Step-by-step explanation:
First, find the slope by using change in y divided by change in x.
Change in y = 5 - 2 = 3
Change in x = 2 - 1 = 1
This means that the slope is 3/1 = 3.
Then, you put it in the point-slope form so:
(y - 2) = 3(x - 1)

Physical therapists measure strength on a dynamometer, which uses a unit called a foot-pound. Suppose you increase the strength in your elbow joint from 90 foot-pounds to 125 foot-pounds. Find the percent of increase to the nearest percent.
A.
39%
B.
138.9%
C.
28%
Answers
Answer:
A. 39%
Step-by-step explanation:
(125-90)/(90)=(35)/(90)=0.3889 or 39%
To find the percent increase, we need to divide the amount of change by the original amount.
Two snakes race the speed of the first is 24 1/2 inches per minute and the speed of the other is 26 inches per minute how far apart with they be in 3 min? 10 min?
Answers
Answer:
637, 245
Step-by-step explanation:
Speed is the rate of change in the position of an object. The distance between the two snakes after 10 mins is 15 inches.
What is the relation between speed, distance, and Time?We know that sped, distance, and time all are in a relationship to each other. this relationship can be given as,
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given to us
Two snakes race The speed of the first is 24 1/2 inches per minute The speed of the other is 26 inches per minute What is the distance between them after 3 mins?The relative speed between them, as they are moving in the same direction, therefore,
Relative speed = (26-24.5) = 1.5 inches per minute
[tex]\text{Distance between them after 3 mins}= \rm speed \times \rm time[/tex]
[tex]= 1.5 \times 3\ mins\\= 4.5\ inches[/tex]
Thus, the distance between the two snakes after 3 mins is 4.5 inches.
What is the distance between them after 10 mins?The relative speed between them, as they are moving in the same direction, therefore,
Relative speed = (26-24.5) = 1.5 inches per minute
[tex]\text{Distance between them after 10 mins}= \rm speed \times \rm time[/tex]
[tex]= 1.5 \times 10\ mins\\= 15\ inches[/tex]
Thus, the distance between the two snakes after 10 mins is 15 inches.

Answer:
9 is the correct answer all the best
Step-by-step explanation:
(x + 0.5)/6 = 19/12
2(x + 0.5) = 19 (multiply 12 on both sides)
x + 0.5 = 9.5 (divide 2 on both sides)
x = 9 (subtract 0.5 on both sides)
The answer is 9.

Answer:
[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]
Step-by-step explanation:
equation of line formula:
[tex]y = mx + c[/tex]
m = slope
c = y-intercept
1) find m
slope formula:
[tex]m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}} [/tex]
take 2 coordinates from the given graph and substitute the values into the slope formula
i) (-1,0)
[tex]x _{1} = - 1[/tex]
[tex]y_{1} = 0[/tex]
ii) (3,2)
[tex]x_{2} = 3[/tex]
[tex]y_{2} = 2[/tex]
substitute the values into the slope formula
[tex]m = \frac{2 - 0}{3 - ( - 1)} [/tex]
[tex]m = \frac{2}{4} [/tex]
[tex]m = \frac{1}{2} [/tex]
2) find the half equation of the line by substituting the value of m into the equation of line formula
[tex]y = \frac{1}{2} x + c[/tex]
3) find c by substituting either coordinate into the half equation
(3,2)
x = 3
y = 2
[tex]2 = \frac{1}{2} (3) + c[/tex]
[tex]2 = \frac{3}{2} + c[/tex]
[tex]2 - \frac{3}{2} = c[/tex]
[tex] \frac{1}{2} = c [/tex]
[tex]c = \frac{1}{2} [/tex]
4) find equation of line by substituting the value of c into the half equation
[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]

Answer:
( x , y ) = ( -1,1/2)
Step-by-step explanation:
Solve the equation for X
[tex]\left \{ {{x=-5/3+4/3y} \atop {5x+8y=-1}} \right.[/tex]
Substitute the given value of x into the equation 5x + 8y = -1
5(-5/3+4/3y)+8y=-1
Solve the equation for Y
y=-1/2
Substitute the given value of y into the equation x = -5 / 3 + 4 / 3y
x=-5/3+4/3×1/2
Solve the equation for X
x=-1
The system solution is the computer pair
(x,y)=(-1,1/2)
Check if the ordered pair given to the solution of the system of equations
[tex]\left \{ {{3*(-1)-4*1/2=-5} \atop {5*(-1)+8*1/2=-1}} \right.[/tex]
Simplify the equations
[tex]\left \{ {{-5=-5} \atop {-1=-1}} \right.[/tex]
The ordered pair is the solution of the system of equations, since both equations are true
