Answer 1

Step-by-step explanation:

You can solve this with kinematics or with energy.

Using kinematics, given:

v₀ = 600 m/s

v = 200 m/s

Δx = 0.05 m

Find: a

v² = v₀² + 2aΔx

(200 m/s)² = (600 m/s)² + 2a (0.05 m)

a = -3,200,000 m/s²

Given:

v₀ = 600 m/s

v = 0 m/s

a = -3,200,000 m/s²

Find: Δx

v² = v₀² + 2aΔx

(0 m/s)² = (600 m/s)² + 2(-3,200,000 m/s²) Δx

Δx = 0.05625 m

So the bullet needs to travel an additional 0.00625 m, or 0.625 cm.

Using energy, the work done on the bullet equals the change in kinetic energy.

ΔKE = W

½ mv² − ½ mv₀² = Fd

½ m (200 m/s)² − ½ m (600 m/s)² = F (0.05 m)

(-160,000 m²/s²) m = F (0.05 m)

F/m = -3,200,000 m/s²

½ mv² − ½ mv₀² = Fd

½ v² − ½ v₀² = (F/m) d

½ (0 m/s)² − ½ (600 m/s)² = (-3,200,000 m/s²) d

d = 0.05625 m

Answers

Answer:

Step-by-step explanation:

the y intercept is at 12 and it slopes down

Answer:

B. the slope is -2, and the y-intercept is 12.

Step-by-step explanation:

i cant really explain stuff that well but basically you have to find the slope. you have to subtract 18-12 and you would get 6. then subtract -3-0 and that would be -3.

you then have to divide 6 (-3) and you would get -2. i never knew how to get 12 tho- sorry lol

The tiles are rectangles 20 cm wide and 25 cm high.
The tiles are sold in boxes.
There are 20 tiles in each box.

Answers

Answer:

Step-by-step explanation:

Answer:

B = 56

Step-by-step explanation:

A + B = 90 degrees

(6x - 8) + (5x + 21) = 90

6x - 8 + 5x + 21 = 90

(6x + 5x) + (-8 + 21) = 90

11x + 13 = 90

11x + 13 - 13 = 90 - 13

11x = 77

11x/11 = 77/11

x = 7

Plug into (5x + 21).

5(7) + 21 =

35 + 21 = 56

B = 56

Identify all of the roots of the function f(x) = x^3 - 5x^2-2x+24

Answers

The roots are -2, 3 and 4.

What are roots?

A solution to an equation, usually expressed as a number or an algebraic formula.

Given:

x³-5x²-2x+24

As, x+2 divides the x³-5x²-2x+24 gives quotient x²−7x+12.

Now,

x²−7x+12.

=x²− 4x -3 x+12.

=x(x-4) - 3(x-4)

=(x-4)(x-3)

Hence, the roots are -2, 3 and 4.

For questions 18-20, if l \\ m, find the values of x and y

Answers

Answer:

Step-by-step explanation:

18). l║m and a transverse is intersecting these lines.

(11y - 32)° = (6x + 7)° [Vertical angles]

-6x + 11y = 39 -------(1)

(3x - 16)° + (6x + 7)°= 180° [Same side exterior angles]

9x - 9 = 180

9x = 189

x = 21

Now substitute the value of x in the equation (1)

-6(21) + 11y = 39

11y = 39 + 126

y = 15

19). l║m and a transversal is intersecting these lines.

(8x - 14)° + (5y + 16)° = 180° [Linear pair of angles]

8x + 5y = 178 --------(1)

(8x - 14)° = (5x + 34)° [Alternate exterior angles]

8x - 5x = 48

3x = 48

x = 16

From equation (1)

8(16) + 5y = 178

128 + 5y = 178

5y = 178 - 128

y = 10

20). From the figure attached,

m∠CAB = (5y - 23)°

Since sum of interior angles of a triangle is 180°

m∠CAB + m∠ACB + m∠ABC = 180°

(5y - 23)° + (2x + 13)° + (47)° = 180°

2x + 5y = 143 ------(1)

(5y - 23)° = 3x°

3x - 5y = -23 -----(2)

Equation (1) + Equation (2)

(2x + 5y) + (3x - 5y) = 143 - 23

5x = 120

x = 24

From equation (1)

2(24) + 5y = 143

48 + 5y = 143

5y = 95

y = 19

A pool estimate that 43% of likely voters are in favor of additional restrictions on teen drivers the Poll has a margin of error of plus or minus 4%. Write and solve the absolute value equations to find the minimum and maximum percent of voters that support the restriction

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Estimated number of voters in favor of additional restriction = 43%

Margin of Error = ±4%

Write and solve the absolute value equations to find the minimum and maximum percent of voters that support the restriction:

Minimum percentage of voters = 4% lesser than the estimated number of voters

Maximum percentage of voters = 4% greater than the estimated number of voters

Let number of voters = v

|v - 43%| = ±4%

v = - 4% + 43% = 39% = minimum percentage

v = +4% + 43% = 47% = maximum percentage

39% ≤ v ≤ 47%
