Step-by-step explanation:

Answer and explanation:

Assuming the frog jumps from -10 for all jumps, if the frog decides to make all 4 jumps then :

8 units jump= -2 or -18

4 units jump= -6 or -14

2 units jump= -8 or -12

1 unit jump = -9 or -11

If the frog decides to make one jump then skip the others then:

Either it makes 8 units jump= -2 or -18

Or 4 units jump= -6 or -14

Or 2 units jump= -8 or -12

Or 1 unit jump = -9 or -11

If it decides to make 2 jumps and skip the others then:

Either it makes 8 units jump= -2 or -18

and 4 units jump= -6 or -14

Or 2 units jump= -8 or -12

and 1 unit jump = -9 or -11

Or any other mix of units of jump twice

If it decides to make 3 jumps and skip the others then:

Either it makes 8 units jump= -2 or -18

and 4 units jump= -6 or -14

and 2 units jump= -8 or -12

Or 1 unit jump = -9 or -11

and 4 units jump= -6 or -14

and 2 units jump= -8 or -12

Or any other mix of 3 jumps

If it decides to make no jump at all then the frog would remain at -10

Answer:

D

Step-by-step explanation:

The equation for the line shown in the graph will be y = - x + 10. Then the correct option is D.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

From the equation, the y-intercept is 10. Then the equation is given as,

y = mx + 10

From the graph, the line is passing through (2, 8). Then the slope is given as,

8 = m(2) + 10

8 = 2m + 10

- 2 = 2m

m = - 1

The equation for the line shown in the graph will be y = - x + 10. Then the correct option is D.

The equation T = 4v + 3 is solved for v will be written as v = (T - 3) / 4.

The possible value of the variables that satisfy the equation which is known as the solution of the equation.

The equation is written below.

T = 4v + 3

The degree of the equation is one. Then the equation is given a linear equation.

Solve the equation for v, then we have

T = 4v + 3

Subtract 3 from both sides, then we have

T - 3 = 4v

Divide the equation by 4 into both sides, then we have

v = (T - 3) / 4

The equation T = 4v + 3 is solved for v will be written as v = (T - 3) / 4.

The third number line shows the inequality.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

Aiko is selling books for $12 each. She wants to make more than $180 in book sales.

and, the inequality 12b > 180 can be used to determine the number of books, b.

Now, solving the inequality

12b > 180

b > 180/12

b > 15

Hence, the third number line shows the inequality.

Step-by-step explanation:

48/5x-2 = 40/2x+7

48(2x+7) = 40(5x-2)

96x+336 = 200x-80

-96x           -96x

336 = 104x-80

416/104 = 104x/104

x = 4

The value of x is equal to 4.

we have to determine the value of the x.

Two triangles are similar if they have the same ratio of corresponding sides and equal pairs of corresponding angles.

48/5x-2 = 40/2x+7

48(2x+7) = 40(5x-2)

96x+336 = 200x-80

-96x           -96x

A

Answer:

(5,-2)

Step-by-step explanation:

Answer:

The correct option is A: 4.29 N.

Step-by-step explanation:

The magnetic force is given by:

[tex] F = qv\times B = qvBsin(\theta) [/tex]

Where:

q: is the charge = 7.12x10⁻⁶ C

v: is the speed = c/2 = 1.5x10⁸ m/s

B: is the magnetic field = 4.02x10⁻³ T

θ: is the angle = 90° (the speed is perpendicular to the magnetic field)

Hence, the force on the charge is:

[tex]F = qvBsin(90) = 7.12 \cdot 10^{-6} C*1.5 \cdot 10^{8} m/s*4.02 \cdot 10^{-3} T = 4.29 N[/tex]

Therefore, the correct option is A: 4.29 N.
